Journal articles on the topic 'Nigerian Pottery'

The pottery narratives of Nigeria majorly linked with the activities of a great British potter Michael Cardew who Established pottery centres in Nigeria, and trained many Nigerians in Pottery. Cardew studied under Bernard Leach (1887 – 1979) who travels extensively and taught pottery around the world.Leach studied pottery under Master Kenzan VI in Japan and returned to England in 1920 to establish his own pottery at St. Ives with Shoji Hamada. The impact in pottery created by Cardew in Nigeria from 1950 is a direct British Pottery influence imparted to him by leach at St. Ives. A British potter and artist, Kenneth C. Murray studied pottery under Bernard Leach at St. Ives in 1929 and returned back to Uyo in Nigeria to produce and teach students pottery. Murray produced pottery wares from the Kiln he built at Uyo and took his students to exhibit the ware along with other art works at Zwember gallery (Britain) in 1937. Chief Adam Joshua Udo Ema also studied pottery in 1949 in Britain and later returned to work as a pottery officer at Okigwe Pottery centre as well as established three pottery centres in Nigeria Namely; Ikot Abasi Pottery centre at Etinan, Pottery centre at Mbiafun Ikono, and pottery centre at Ikot Ntot in Abak. Many other Nigerian studied pottery in Nigeria. Lady Kwalii pottery experience was influenced by Michael Cardew. Her pottery influence seen pottery products exhibited in various parts of the world depicted a coordination of Niger and British Pottery influences. A case study design is considered for methodological approach. Data were taken from primary and secondary sources and analyzed respectively. British influence on Nigeria is indeed outstanding.

Pottery-making in parts of Igboland is discussed from an ethnoarchaeological perspective. In line with a long tradition of descriptive studies, the pottery manufacturing processes are here outlined, but emphasis is laid firstly on studying pottery decorations (techniques and motifs) prevalent in parts of Igboland within their socio-cultural and economic contexts; and secondly, on observing and studying how the Igbo people (potters and users of pots) classify pottery products (traditional pottery classification). A second set of observations concerns functions of pots, their distribution, consumption, life span and eventual disposal. Finally, the paper also looks at the social and cultural setting of pottery production — factors which still favour pottery production in Igboland and those that may lead to its eventual abandonment (including the status of potters in Igbo society and the learning process of pottery manufacture).

ABSTRACTThis study investigates production of refractory studio kiln shelves using Afowa clay. In solving firing problems, kiln was the earliest tool used to revolutionalize pottery productions, while shelves are among the furniture inside the kiln where ceramic green/bisque wares are stacked for firing. Most scholars in Nigeria who have written on kiln focused on construction of kiln, little has been done about kiln shelves production. Firing of pottery wares plays important roles in production of earthen or glaze wares. This paper deals with the production of shelves and suggests possible ways it can be used for stocking the kiln. It x-ray the problems associated with cracks on shelves and how to check them. The researcher also elaborates on different methods of propping shelves (bats) in stocking a kiln. Kiln setting for glaze firing follows a general principle of proper foot-cleaning and non-contact. The mechanical and physical properties of the composites are determined. Findings are made to show that there are improvement in hardness value, strength and compressive strength of the developed composites. Also, this research will impact positively on potters and institutions and will further open up research and creative development. It will hopefully discourage further importation of refractory materials and serves as reference material to potters. Keywords: Production, studio, kiln, Firing and shelves.

AbstractPottery has been defined and redefined by many scholars of history and anthropologist. Pottery is wrapped in the past with no written record; this study intends to work on the historical analysis of form, style and techniques of Pottery tradition, the various pottery associations in Nigeria will be identified and discussed. The study will also examine the symbolic meaning of each of the traditions, it will also project the aesthetic qualities, and the effects of new ideas of pottery of the indigenous Benin people, and how pottery is interpreted/ the study hopes to compile and analyze forms of pottery that will rekindle interest in pottery, and serve as reference point for the future generation.

New archaeological research in Borno by the Johann-Wolfgang-Goethe-Universität, Frankfurt am Main, Germany, has included the analysis of pottery excavated from several sites during the 1990s. This important investigation made us search through our old files for a statistical analysis of pottery from the same region, which although completed in 1981 was never published. The material came from approximately one hundred surface collections and seven excavated sites, spread over a wide area, and resulted from fieldwork in the 1960s and 1970s. Although old, the analysis remains relevant because it provides a broad geographical context for the more recent work, as well as a large body of independent data with which the new findings can be compared. It also indicates variations in both time and space that have implications for the human history of the area, hinting at the ongoing potential of broadscale pottery analysis in this part of West Africa and having wider implications of relevance to the study of archaeological pottery elsewhere.

Mortality and morbidity figures associated with tuberculosis are generally scary. Raw materials involved in the pottery making process contain crystalline silica which has been documented as risk factors to the development of tuberculosis. Unfortunately Nigeria pottery workers have no formal occupational health services. This study determined the knowledge of risk factors and preventive practices against pulmonary tuberculosis among pottery workers in Oye, Nigeria. A descriptive cross sectional study was carried out among 198 pottery workers selected using multistage sampling method. Research instrument consisted of a semi structured interviewer administered pretested questionnaire. Data was analyzed using the SPSS software version 23.0. Results shows that a one hundred and ninety four (98%) of the respondents have ever heard of pulmonary tuberculosis, 178(89.9%) of them don't know whether clay soil contained chemicals that could predispose them to tuberculosis. Only 64.1%, 56.6% and 59.1% had good mean general knowledge, good mean knowledge of prevention and good mean perception scores to tuberculosis respectively. Sixty three (31.8%) said that pottery workers are among those at risk of developing Tuberculosis (TB). Only 51 (25.8%) said they used protective equipment. Predictors of good general knowledge and good perception of TB include age above 24 years, being female, having post primary school education, having spent more than 5 years in pottery business and using protective devices (p<0.005). There is need for recognition and prioritization of all silica-exposed workers for screening and treatment services in anti-TB programmes of the Government.

Recent Investigation of an archaeological site in southwest Nigeria during the Late Stone Age revealed additional information about the cultural development of the area. On Iresi Hills two rock shelters (Ajaye and Cherubim & Seraphim) were investigated in two seasons from 2017 to 2018 during which pottery, ground stone axes and microlithics were excavated. Although there is no clear break in the stratigraphy, the findings show clear demarcation between two cultural layers. The upper layer contains pottery, microlithics and ground stone axes, and ochre while the lower layer is characterized by microlithics only. The site presented a date of about Cal 5653 BP which coincides with a short dry period in the area. Tis paper reports the occupation in Iresi, in southwest Nigeria with a view to fill the gap in the chronology and to interrogate the evidence for Late Stone Age in terms of the culture that existed in between 12000YBP of Iwo Eleru and 2000YBP of Itaakpa and the influence of a change in environment of southwest Nigeria and West Africa in general.

Pottery practice is one of the three-dimensional enterprises of the Urhobo people who inhabit part of the Niger Delta region of Nigeria. The people are also known for the production of massive sculptures in wood and mud. Many of the pottery products of the people are, as is the case with their sculptures, configurations of volumes. The expressiveness of these pots is, in part, determined by the way in which the constituting volumes meet each other. In most literature that is available on this art practice of the people, this structural feature is diminished in importance or not considered as a contributing element to the general aesthetics of the ware. This paper interrogates the structural elements that constitute the pots. This is done by dissembling the pots into their structural components (volumes) and analyzing the manner of their coming together to constitute the pot. The findings show that two basic transitions are used as aesthetic attributes in the pottery products from the study area. The study also reaffirms that the extent to which an object satisfies the purpose for which it is made is a strong determinant of the aesthetic value ascribed to the object by a people.

Túnráyọ̀ Àyìnkẹ́ Àyìnlá of Alámọyọ, Adéta, Ìlọrin in Nigeria is the thrust of this study. Fondly called Àyìnkẹ́ Alámọyọ in the pottery ceramics circle. Túnráyọ̀ is a burnisher extraordinaire and indeed a veteran of several decades. Madame Túnráyọ̀ Àyìnlá is unarguably one of the few Nigeria’s senior citizens still proficient in pottery practice with features in pockets of literature. Prolific as she is, it is sad to note that, her life, practice, and contribution have been masked and left unsung for too long. A vacuum this study attempts to fill; unveiling facts on her family, training, and practice. Finding revealed she is nee Àlíù, putting her training and graduation at ages eight and eighteen; coupled with over sixty (60) years of burnish black glaze culinary wares production. In conclusion, the study put Túnráyọ̀’s proficiency test and its findings hoped to place her on the global front of burnish ceramist.

Niger Delta region is very rich in oil and gas deposits, clay, agricultural land, fisheries, extensive forest and other resources. They are nine states which make the region namely, Abia, Akwa Ibom, Bayelsa, Cross River, Delta, Edo, Imo, Ondo and Rivers. The most oil producing communities among them are Akwa Ibom, Bayelsa, Edo, Delta and Rivers State. Clay is equally found in abundance in all the states like crude oil is found in Niger Delta communities. The available clay mineral in the region has the capacity to transform the nation’s economy if properly utilized. Clay is the basic material for pottery or ceramics production. It is also used to ease the penetration of pipes in drilling of crude oil. This paper looks at the practice of pottery in Niger Delta Area with a focus on pottery practice in both Akwa Ibom and Rivers States. Indigenous and contemporary pottery or ceramics practices in these communities indeed have played vital role in the economic, social religious and cultural ways of life of the people. Clay products such as dinnerware and sanitary wares and others are highly sought for and they have the capacity to boast the national economy as experienced in other nations such as Japan, Italy, Britain, United States of America, India and China among others. Data were collected from both primary and secondary sources and were subsequently assessed. The result shows that proper utilization of clay found in Niger Delta has the potential to create numerous job opportunities for the teaming population of youths in the region. The availability of abundant clay in the region, if well harnessed could adequately compete with crude oil exploitation for economic purposes in the region.

Frit is an essential material required in the composition of low temperature glazes. Unfortunately, up till the year 2020 appropriate furnace for local production of frit is scarce in Nigeria. This may be due to the prohibitive prices of customary refractory materials, exorbitant cost for construction of a standard frit furnace, and the epileptic power supply to run a frit producing plant. Consequently, previous attempts to produce frit locally ended up in losses and products froth with impurities. In this work, the continuous-flow frit kiln with a sloping floor design was modified and a prototype was constructed using locally sourced refractory. The working section was lined with highly corrosion resistance monolith produced with a ramming mass composed of zircon and kaolinite. It has a volume of 10.62 litre. The furnace runs on butane gas, it is fed with pre-treated precursor in granules form and capable of continuous production of 30 kg of frit per hour (kg/h) at 1100 oC. With the appropriate burner, the furnace achieved the optimum operation temperature of 1100oC within two hours. The design is suitable for private studio, research and educational institutions. It can also be scaled up for industrial uses.

To what extent birds provide the ecosystem service of pest control in subsistence farms, and how this service might depend on retained natural habitats near farmlands is unexplored in West Africa. To fill this knowledge gap, we placed plasticine mimics of insect pests on experimentally grown crops on the Mambilla Plateau, South Eastern Nigeria. We recorded bird attacks on the mimics and the proportion of mimics removed by birds. We also determined the influence of distance of crops from forest fragments on both attack and removal rates. We placed 90 potted plants of groundnut (Arachis hypogea) and bambara nut (Vigna subterranea) along 15 transects running 4.5 km from forest edge into open grassland. Each plant had six of the 540 mimics in total placed on their leaves. We inspected the potted plants weekly for 12 weeks to record (i) the presence of bird beak marks on mimics, and (ii) the number of missing mimics. Once a week we collected all the mimics from the plants and counted the number of assumed beak marks. After counting we replaced the mimics on the plants, mark free. We found a strong positive correlation between the abundance of insectivorous birds and the mean number of missing mimics and/or bird attack marks on mimics. However, this positive effect of insectivorous bird abundance on prey mimic attack/removal became less strong the farther they were from a forest fragment. We found increased predation rates and abundance of insectivorous birds closer to forest fragments. Our data suggest that pest predation may be a key ecosystem service provided by insectivorous birds on Nigerian farmlands. Farmlands that are closer to forest fragments may experience a higher rate of pest control by insectivorous birds than those further away, suggesting that retaining forest fragments in the landscape may enhance pest control services in sub-Saharan subsistence farms.

Kaolin of sedimentary origin in the Abeokuta area, southwestern Nigeria was studied to determine its mineralogy and geotechnical properties as well as possible industrial applications. Samples of kaolin were collected from different mine sites in the Abeokuta area. Geotechnical test was also performed to determine the grain size parameters and plasticity of the kaolin samples. Samples were also subjected to mineralogical and morphological analysis using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Results revealed that kaolin samples have clay, silt and sand fraction ranging from 7.3 -53.93%, 29.56 – 53.72% and 1.8 to 29.56% respectively. XRD and SEM results revealed that minerals in kaolin are kaolin, quartz, rutile and anatase. Industrial and geotechnical appraisal revealed that some of the samples with high content and low quartz content can be used in production of ceramics and paper while cannot be used in some industrial application such as pottery and production of ceramics due to the grain size geotechnical properties and mineralogy.

The objective of the research was to determine the antifungal activities of Guiera senegalensis L. and Mangifera indica L. leave extracts against most frequently occurring sorghum pathogen of the loose smut (Sporisorium cruentum) in Nigeria. Methanolic extracts from Guiera senegalensis L. and Mangifera indica L. were tested at concentrations of 250, 125, 62.5, and 31.2mg/ml as potential sources of antifungal agents for Sporisorium cruentum. All extracts exhibited moderate to good activities on the tested fungi with minimum inhibitory concentrations (MICs). The test organism was sensitive to the G. senegalensis extracts, with 14mm and 10mm in diameter at 250mg/ml and 125mg/ml, respectively. The test organism was sensitive to M. indica leaf extract with 12mm in diameter at 250mg/ml. The results showed that both extracts exhibited inhibitory effects at different concentrations against the test organism. Therefore, it is concluded that extracts of G. senegalensis and M. indica could be used in controlling the fungal pathogen of sorghum loose smut (Sporisorium cruentum). Keywords; antifungal activities, Sporisorium cruentum, Guiera senegalensis, Mangifera indica

This study assessed an electronic wallet (e-wallet) system and determinants of cassava farmers? participation in off-farm activities in Abuja, Nigeria. A sample of 67 cassava farmers was selected through a multi-stage sampling technique from six selected agricultural extension blocks. Primary data were used. Data were collected using a well-structured and well-designed questionnaire. The analytical tools used were descriptive statistics and maximum likelihood estimates using the logistic regression model. The results indicated that an electronic-wallet is an innovative, motivational mobile phone technology, the first in sub-Saharan Africa to distribute mobile phones to farmers which bring fertilizers, improved seeds, financial services, and agricultural information tips to farmers, and this increases yields and output. The electronic wallet system targeted 20 million farmers with an intention to distribute 10 million mobile phones to farmers in 4 years. In 2014, 1,000 agro-dealers and fourteen million five hundred farmers were registered on the electronic wallet system respectively. Also, one million two hundred farmers have also received inputs via the electronic-wallet system. The electronic-wallet system added an estimated 30-40 billion dollars to Nigeria?s Gross Domestic Product in 2014. Furthermore, the result shows that the age of most sampled cassava farmers fell between 36 and 50 years. About 94% of sampled cassava farmers were male. Off-farm income has the potential to improve the income of farmers. These types of activities undertaken by cassava farmers off the farms include: teaching, tailoring, hunting, pottery, blacksmithing, petty trading, etc. Farmers? age, farming experience and number of off-farm activities were significant variables influencing farmers? participation in off-farm activities at P ? 0.01; P ? 0.10; and P ? 0.01 respectively. The coefficient of Nagelkerke (R2) value was 0.751.This shows that the explanatory variables explain the level of participation of cassava farmers in off-farm activities at 75% level of confidence. The coefficient of Cox and Snell determinant (R2) value was 0.547. Off-farm employment is an alternative strategy and has potentials to improve the income and well-being of farmers. The study recommends that government and nongovernment organizations should introduce innovations, motivations, interventions, policies that improve crop production and support the off-farm sector in order to create job opportunities so that poor households can participate and benefit directly.

A field potted experiment was carried out in Asaba area of Delta State, Nigeria to evaluate sources and rates of organic manures (poultry and farmyard) on growth responses of Gongronema latifolium in an acid soil environment. It was a factorial experiment laid out in a randomized complete block design replicated 3 times. Data on plant height, number of leaves/branches, leaf area and stem girth were collected at 3, 5, 7, 9, 11 and 13 Weeks after sowing (WAS) and subjected to analysis of variance. The results that the effects on growth parameters of the crop were not significant and that higher application rates significantly increased plant height, number of leaves/branches and stem girth of G. latifolium. Application rates of 15 and 20 t/ha of both poultry and farm yard manures increased plant height from 10.45 cm to 12.52 cm and 8.12 cm and 10.68 cm respectively. The overall result indicated that the higher rate of organic manure, the better the response of growth indices of G. latifolium, though interaction effect was not significant. Poultry manure produced higher values of growth indices than farm yards manure, hence was recommended for increased productivity of G.latifolium in the study area.

Tomato plays an important nutritional role in human diet. Although, Nigeria is the largest producers of tomato in Africa, its production is threatened by the invasive polyphagous insect pest belonging to the genus Liriomyza. An experiment was conducted to enumerate the level of damage of the agromyzid fly Liriomyza spp on the tomato variety, UC82B. Infestations were observed on potted tomato plants and studied from December 2016 to March, 2017. The experimental treatment consisted of both screen house and field trials. The experiment was laid out in a Randomized Complete Block Design with four replicates. Data were collected on the number of tomato leaves mined by larvae of the pest every week after transplanting (WAT) and on the total weight of tomato fruits harvested. Using t-test statistical analysis, results revealed that tomato plants grown in the field were the most infested by the insect pest from 5 to 10 WAT having significantly higher (P < 0.05) mean population of the pest when compared to the screen house which had little or no infestation. However, there was no significant difference in the leaf damage by Liriomyza spp from 2 to 4 WAT. Tomato fruits harvested at the end of the experiment were weighed and observation showed that the screen house gave more fruit yield (90.80±6.10g) compared to the field experiment (24.20±2.27g) which was significantly lower due to leaf miner flies’ damage on tomato leaves. Therefore, appropriate control measures of the insect pest are recommended where screen houses may not be accessible.

Earthworms are one of the most important soil organisms in tropical ecosystem as they influence mineralogical, structural and microbial composition of soil. The study investigated the effect of interaction between two Nigerian earthworms Eudrilus Eugeniae and Irridodrilus sp and Ageratum species (AG) on soil physicochemical properties in potted experiment. The treatment consisted of 1000g subsoil treated with ageratum (AG); Ageratum + soil inoculated with Eudrilus Eugeniae (AE), Ageratum + soil inoculated with Irridodrilus sp (AI) and control soil not treated (CO). The results of the study showed remarkable differences between the treatments in soil physicochemical properties. The pots inoculated with Eudrilus Eugeniae (AE) relative to other treatments produced high quality ion exchange as evidence from the high (CEC) recorded, enhanced soil aggregation 73% compared to 52% recorded in AI, stabilization of soil aggregates and enhanced availability of nutrient elements by 150% compared to 120% observed in AI. High level of soil pH (9.15) was recorded in AE. AG induced 62% increase in soil erodibility and only 9% increase in availability of soil nutrients. AG was found to be toxic particularly to Irridodrilus whose percentage survival was 0% relative to 67% of Eudrilus Eugeniae whose weight loss was 27%. Ageratum is a bio-pesticide and bio-fertilizer of which its production is simple and cost effective and the efficacy for soil management will require the presence of active soil organisms like earthworms to process Ageratum adequately as was found in this study. The primary materials used in this study are abundantly available and within the reach of farmers. The production and application is eco-friendly, promotes sustainable soil productivity, soil conservation and environmental health. This technology will discourage the use of chemical pesticides and fertilizers in the study area if well integrated in crop production activities.

Spent Engine oil (SEO) is a common environmental pollutant generated after engine services. Disposing SEO is a serious environmental issue in Nigeria as generators end up disposing it in water drain systems, rivers, open vacant plots and agricultural lands. Thus, the need to assess the impact of such disposal on environmental components becomes imperative. Using a completely randomized design, a control and seven treatments of SEO (T0: 0 ml, T1: 5 ml, T2: 10 ml, T3: 15 ml, T4: 20 ml, T5: 25 ml, T6: 50 ml, T7: 75 ml) were applied to potted soil for cowpea planting. Plant height, leave number, yield, heavy metal load and hazard quotient were assessed. Baseline heavy metal analysis showed the SEO contained lead and cadmium at 0.003 mg/kg and 0.462 mg/kg respectively. There was significant reduction in plant height (T0: 50.72 cm, T3: 37.36 cm, T7: 24.33 cm), number of leaves (T0: 25.91, T3: 21.57, T7: 17.67), seed weight (T0: 24.40 g, T3: 16.38 g, T7: 5.03 g) and plant weight (T0: 171.60 g, T3: 136.60 g, T7: 54.70 g) in contaminated soil with increasing SEO concentration (P<0.05). Cowpea grown on contaminated soil accumulated cadmium in seeds (T0: 0.000 mg/kg, T3: 0.057 mg/kg, T7 0.119 mg/kg) and in roots (T0: 0.000 mg/kg, T3: 0.079 mg/kg, T7: 0.263 mg/kg) with hazard quotient ranging from 0.084 to 0.216. This study revealed that increasing environmental pollution through indiscriminate SEO increases the possibility of health risk by elevating hazard quotient and this should therefore be discouraged.

Leaf-blight disease of Colocasia caused by Phytophthora colocasiae Raciborski has been a serious impediment to cocoyam production in Nigeria. Disease severity and susceptibility of the two most cultivated local varieties “Ugwuta” (Colocasia esculenta var. antiquorum) and “Nkashi Colocasia esculenta var. esculenta) were investigated. Disease severity was visually estimated as the percentage leaf surface affected by blight, lesion or lesion-related chlorosis for each leaf of a plant using a seven-point scale of 0, 5, 10, 25, 50, 75 and 100% in three locations: Ede-Oballa, Nsukka Urban and Obukpa. Susceptibility was assessed on 2 months old potted plants of each variety inoculated with a 7-day old culture of P. colocasiae. Diameters of lesions on inoculated leaves were recorded from the 3rd - 8th day after inoculation. Data on severity were subjected to ANOVA and susceptibility of the varieties was compared with t-test. Results revealed significant LSD=4.96 (0.05) and varying degrees of leaf blight severity among varieties and locations. Variety antiquorum had significantly higher severities of 42.08, 46.40 and 47.42% at Ede-Oballa, Nsukka Urban and Obukpa respectively, compared to 34.85, 36.55 and 28.19% recorded by var. esculenta at these locations, respectively. Similarly, var. antiquorum had greater lesion diameter ranging from 0.65±0.07 cm - 3.70±0.14 cm and average diameter of 2.4±0.16cm compared to var. esculenta which had 0.41±0.14cm - 3.12±0.19 cm and average diameter of 1.80±0.16. This research has shown that varieties and locations affect the severity and susceptibility of Phytophthora leaf blight disease. This could be a guide to farmers having known that var. esculenta is less severe to Phytophthora leaf blight disease.

While strategizing towards achieving improved soil fertility for sustainable tropical crop production, timely application of fertilizers on regular basis alone is not the University of Technology, Ogbomoso, Oyo State, Nigeria best approach, particularly on polluted soils. However, seeking for reliable natural, biological and environment friendly means of ensuring effective riddance of toxic elements or heavy metals from tropical agricultural soils is equally a worthwhile technology. An open-field potted experiment was conducted during early raining season of 2016 (March-July), at the Teaching and Research Farms of Oyo State College of Agriculture and Technology, Igboora, to investigate the effect of spent engine oil polluted soil conditions on performance and heavy metal accumulation potentials of Ceratothecasesamoides. Spent engine oil was applied at different concentrations (0.0ml, 50.0ml, 100.0ml, 150.0ml, and 200.0ml to each pot containing 7kg soil. Four pots per treatments were used. The trial was arranged in Completely Randomised Design (CRD), replicated three (3) times. Data were collected on growth parameters (number of leaves, plant height, stem girth, leaf length and leaf breadth). The data were subjected to analysis of variance (ANOVA) and Duncan Multiple Range Test (DMRT) was used to the means. Pre and post-cropping soil analyses were carried out, for determination of nutrient concentrations. Also, after the termination of the experiment, plant samples were collected from each of the pots for oven-drying followed by determination of nutrient concentrations (including the heavy metals). Oil pollution significantly affected growth and heavy metal accumulation of the test-crop. Growth decreases with increasing rate of lubricant application, while the heavy metal concentrations in the test-crop increased with increasing concentrations of the applied spent engine oil. Thus, Ceratothecasesamoides is a wild plant which could be easily exploited for its heavy metals hyper-accumulative or phyto-extractive potentials, so as to reclaim heavy metals polluted soils from toxicity, for sustainable crop production.

Plumeria spp., native to tropical America, are popular small trees grown widely in tropical areas of the world and as potted plants elsewhere. P. rubra and P. obtusa cultivars and hybrids are most common. A rust disease of a Plumeria sp. (likely P. rubra based on pointed leaf tips, leaves more than 18 cm (7 inches) long, and high rust susceptibility) was observed in November 2008 and again in June 2009 on homeowner plants in Baton Rouge, LA. A survey of five Baton Rouge retail nurseries in September 2009 revealed that 87% (90 of 103) of the plumeria plants were heavily infected with rust. Early symptoms included numerous 1-mm chlorotic spots on adaxial leaf surfaces followed by leaf chlorosis, necrosis, and abscission. Uredinia were numerous, mostly hypophyllous and yellowish orange. Urediniospores were catenulate, orange en masse, verrucose, globose, ovoid, ellipsoidal or angular, and measured 21.8 to 41.9 × 16.4 to 32.8 μm (average 29.4 × 22.6 μm). The rust was identified as Coleosporium plumeriae Pat. (= C. plumierae) (3). Teliospores were not found during this study. Pathogenicity tests were performed by spraying urediniospores (20,000/ml of deionized water) on three healthy Thai hybrid plumeria plants. Five leaves of each plant were misted with water and covered with plastic bags and three to five leaves were inoculated. Plants were held at 27°C for 27 h in a dew chamber and then moved outdoors. Typical rust symptoms and uredinia with urediniospores developed in 10 days on all inoculated leaves while noninoculated leaves remained healthy. Characteristics and spore measurements matched those of the rust from original infected plants. Additional plumeria rust inoculations were made to other Apocynaceae family members that included Allamanda cathartica, Catheranthus roseus (Madagascar periwinkle), Mandevilla splendens, Nerium oleander, and Vinca major. Catheranthus roseus was very susceptible to C. plumeriae with chlorotic leaf spots developing on the six inoculated plants after 8 days and uredinia with urediniospores appearing after 11 days. None of the other plant genera were susceptible to the rust. Plumeria rust was also observed on plumeria trees in urban landscapes in peninsular (Penang) and Bornean (Kota Kinabalu, Sabah) Malaysia in December 2007. To confirm identity, ~1,000 bp of nuclear rDNA 28S subunit from each (Lousiana, Penang, and Kota Kinabalu) was sequenced with rust-specific primers (1) and shared 100% identity (GenBank No. GU145555-6). Plumeria rust was first found on the island of Guadeloupe (3) and then spread to Central and South America. It has been known from Florida since 1960 under the synonym C. domingense (2), but has not been reported elsewhere in the continental United States. In more recent years, plumeria rust has spread to Hawaii, many Pacific islands, India, China, Taiwan, Thailand, Australia, and Nigeria (4). To our knowledge, this is the first report of plumeria rust from Louisiana and Malaysia and of susceptibility of another member of the Apocynaceae, Madagascar periwinkle, to C. plumeriae. Voucher material from Louisiana and Malaysia has been deposited in the Mycology Herbarium of Louisiana State University (LSUM). References: (1) M. C. Aime. Mycoscience 47:112, 2006. (2) Anonymous.

FAKTOR-FAKTOR YANG MEMPENGARUHI MORTALITAS PADA PASIEN DENGAN FRAKTUR COSTA: Literature Review Anna Tri Wahyuni1), Masfuri2), Liya Arista3)1,2,3 Fakultas Ilmu Keperawatan Universitas Indonesia ABSTRAK Cedera paling umum yang terjadi pada trauma tumpul adalah fraktur costa (patah tulang iga/rusuk) dimana mekanisme cedera berpotensi mengancam jiwa. Pasien fraktur costa yang menunjukkan tingkat keparahan trauma lebih dari 90% melibatkan kepala, perut dan ekstremitas. Nyeri yang dirasakan akibat dari fraktur costa berkontribusi pada gangguan pernafasan, peningkatan resiko pneumonia dan gagal nafas yang meningkatkan angka morbiditas dan mortalitas. Pedoman penanganan fraktur costa sangat dibutuhkan untuk terjadinya komplikasi. Studi literature ini bertujuan menganalisis faktor-faktor yang mempengaruhi mortalitas pada pasien fraktur costa. Metode penulisan artikel ini menggunakan literature review yang didapat melalui 5 online database yaitu Sage Publishing, Science Direct, SpringerLink, Pub Med dan Google Scholar. Kriteria inklusi jurnal terkait meliputi: free fulltext, berbahasa Indonesia atau Bahasa asing lainnya, metode penelitian prospective, retrospective, case-control, cohort dan terbit antara tahun 2004-2021. Kata kunci yang yang digunakan dalam pencarian adalah “Respiratory depression OR Respiratory failure AND fraktur ribs AND Mortality”. Dari pencarian artikel diperoleh hasil akhir sebanyak 7 artikel yang relevan dan dilakukan proses review. Artikel tersebut menunjukkan hasil bahwa angka mortalitas dipengaruhi oleh faktor usia, skor keparahan cedera, jumlah patah tulang rusuk, dan implementasi penanganan infeksi. Faktor usia, tingkat keparahan cedera dan jumlah tulang rusuk yang patah menentukan tinggi rendahnya angka mortalitas pasien fraktur costa. Penanganan yang tepat dan manajemen nyeri yang sesuai dapat mempengaruhi penurunan angka morbiditas dan mortalitas pasien dengan fraktur costa. Pengembangan intervensi perawatan pasien fraktur costa terkait manajemen nyeri dan kontrol infeksi menjadi penelitian menarik selanjutnya.Kata kunci : Depresi pernafasan, gagal nafas, fraktur iga, angka kematian, angka kesakitanABSTRACT The most common injury in blunt trauma is a rib fracture, where the mechanism of injury is potentially life-threatening. Patients with rib fracture whose severity of the injury is greater than 90% are associated with damage to the head, abdomen, and extremities. Pain from rib fractures contributes to respiratory failure, increasing the risk of pneumonia and respiratory failure, which increases morbidity and mortality. Recommendations are needed for the treatment of complicated rib fractures. This literature study aims to analyze the factors that influence mortality in rib fracture patients. The method of writing this article uses a literature review sourced from 5 online databases, namely Sage Publishing, Science Direct, SpringerLink, Pub Med, and Google Scholar. The inclusion criteria for related journals included: free full text, in Bahasa or another foreign language, prospective, retrospective, case-control, cohort study method, and published between 2004 and 2021. Keywords used in the search were: "respiratory depression OR respiratory failure AND rib fractures AND death." From the article search results, we obtained 7 relevant articles which are the final results and a review process is carried out. The article showed that mortality was influenced by age, injury severity score, number of rib fractures, and infection control practices. The mortality rate of patient with rib fracture is determined by Factors such as age, severity of injury, and number of rib fractures. Appropriate care and adequate pain management can help reduce morbidity and mortality in patients with rib fractures. Another interesting research is the development of interventions in the treatment of rib fracture patients related to pain management and infection control.Key words: respiratory depression; respiratory failure; rib fracture; mortality; morbidity.

Berdasarkan Western Trauma Association (WTA) sekitar 10% kematian pada orang dewasa muda disebabkan oleh cedera patah tulang rusuk yang melibatkan kepala, perut dan ekstremitas. Sebaliknya, pasien lanjut usia dengan patah tulang rusuk memiliki setidaknya 20% kematian yang secara langsung menyebabkan gagal napas progresif dan pneumonia (Brasel et al., 2017). Risiko pneumonia meningkat sebesar 27%, dan kematian meningkat sebesar 19% untuk setiap fraktur costa lebih dari 2 pada kelompok lanjut usia (Wanek & Mayberry, 2004). Pasien dengan trauma dada atau fraktur costa harusnya dilakukan pemantauan ketat sejak masuk rumah sakit, 24 jam pertama merupakan identifikasi awal adanya komplikasi yang menyebabkan depresi pernafasan. Menurut penelitian Coary, et.al (2020) fraktur costa adalah cedera paling serius pada 55% pasien berusia di atas 60 tahun yang menyebabkan kematian karena 90% dari patah tulang rusuk menunjukkan cedera tambahan pada pemeriksaan sistemik. Trauma langsung dan hipoventilasi yang diinduksi nyeri menyebabkan komplikasi pernafasan sehingga menjadi beban morbiditas dan mortalitas. Komplikasi yang sering terjadi adalah pneumotoraks diikuti hemothoraks, kontusio paru dan flail chest.Nyeri adalah suatu pengalaman sensorik yang multidimensional dengan fenomena yang berbeda dalam intensitas (ringan,sedang, berat), kualitas (tumpul, seperti terbakar, tajam), durasi (transien, intermiten,persisten), dan penyebaran (superfisial atau dalam, terlokalisir atau difus) (Bahrudin, 2018). Induksi nyeri pada pasien dengan fraktur costa menyebabkan pasien kesulitan bernafas dimana keparahan memar paru yang mendasarinya signifikan dengan terjadinya hipoksemia atau gangguan pernafasan. Hal ini menyebabkan pasien cenderung membatasi pergerakan dan menjadi tirah baring lama. Kondisi tirah baring lama menyebabkan tubuh mengalami penurunan berbagai fungsi secara sistematis, yang disebut dengan sindroma dekondisi dan rentan terjadinya infeksi (Hashem, Nelliot, & Needham, 2016; Hunter, Johnson, & Coustasse, 2014; Phelan, Lin, Mitchell, & Chaboyer, 2018 dalam Ananta & Fitri, 2020).Fraktur costa atau patah tulang rusuk secara klinis penting disebabkan tiga hal yaitu: sebagai penanda penyakit serius cedera intrathoraks dan perut, sebagai sumber rasa sakit yang signifikan, dan sebagai prediktor untuk kerusakan paru, terutama pada pasien usia lanjut. Organ perut yang paling sering terluka adalah hati dan limpa. Pasien dengan patah tulang rusuk kanan, memiliki 19% hingga 56% kemungkinan cedera hati, sedangkan patah tulang sisi kiri memiliki 22% hingga 28% kemungkinan cedera limpa (Wanek & Mayberry, 2004). Kematian pada orang dewasa dan lansia cenderung terjadi kemudian (≥72 jam setelah masuk) dan biasanya sebagai akibat dari kegagalan multi-organ yang dipicu oleh insufisiensi pernapasan dan pneumonia sehingga tingkat kematian secara keseluruhan, tanpa memandang usia, diperkirakan antara 10 dan 12% (Wanek & Mayberry, 2004). Tingkat mortalitas untuk pasien trauma usia lanjut yang mengalami patah tulang rusuk lebih besar daripada mereka yang tidak mengalami cedera toraks (Coary, et.al, 2020). Penelitian yang dilakukan Marini, et.al, (2021) menyatakan indikator penyebab kematian pada pasien fraktur costa dengan atau tanpa trauma kepala dan cedera organ adalah usia, jenis kelamin, ISS (Injury Severe Score), dan GCS (Glasglow Coma Scale).Berdasarkan uraian diatas maka peneliti ingin menganalisis faktor-faktor yang mempengaruhi angka morbiditas dan mortalitas pada pasien dengan fraktur costa untuk meningkatkan pemahaman tentang penanganan fraktur costa serta mengidentifikasi dari beberapa artikel terkini dalam mengurangi mortalitas. METODE PENELITIAN Metode penulisan artikel ini menggunakan literature review yaitu studi yang berfokus pada hasil penulisan yang berkaitan dengan topik, tema atau variabel penulisan.dan dipakai untuk menghimpun data atau sebuah sintesa sumber-sumber yang berhubungan dengan topik penelitian (Nursalam, 2017). Didapatkan 5 database yang dilakukan melalui pencarian elektronik dari yaitu Sage Publishing, Science Direct, SpringerLink, Pub Med dan Google Scholar. Kriteria inklusi telaah jurnal ini adalah free fulltext, berbahasa Indonesia atau bahasa asing lainnya, dengan metode penelitian prospective, retrospective, case-control, cohort dan terbit tahun 2004-2021. Kata kunci yang yang digunakan dalam pencarian adalah “Respiratory depression OR Respiratory failure AND fraktur ribs AND Mortality”. HASIL DAN PEMBAHASAN Berdasarkan hasil studi literature terdapat banyak faktor yang mempengaruhi terjadinya depresi pernafasan pada pasien fraktur costa yang dapat menyebabkan kematian. Terdapat 17.500 artikel yang muncul setelah dilakukan telusur berdasarkan kata kunci dalam google scholar, 10.000 artikel tidak masuk kriteria inklusi, 350 artikel duplikat dengan database yang lain. Kemudian sisanya disaring kembali berdasarkan hasil abstrak, metode dan hasil temuan sesuai topik peneliti yang diinginkan dan diperoleh 7 artikel yang relevan dan tersedia dalam bentuk fulltext. Beberapa penelitian terkait pencegahan depresi pernafasan pada fraktur costa berfokus pada manajemen nyeri baik secara farmakologis maupun non farmakologis. Penanganan dan pemantauan yang ketat dapat mengurangi komplikasi yang menyebabkan terjadinya depresi pernafasan. Berikut faktor-faktor yang mempengaruhi angka morbiditas dan mortalitas pada fraktur costa menurut Coary, et.al (2020) yaitu: (1) Usia, pasien berusia > 65 tahun memiliki kematian 2-5 kali lebih tinggi dibandingkan usia dibawahnya pada kondisi fraktur costa lebih dari dua. Pasien dengan komorbid sering menjadi faktor penyulit ditambah dengan kondisi paru-paru yang buruk (misal: perokok). Faktor pemulihan menjadi terhambat disebabkan osteoporosis, sistem pernafasan yang buruk, gangguan pertukaran gas dan tergambar dari lama rawat inap. (2) Jumlah patah tulang, dari beberapa penelitian meta-analisis diperoleh hasil jumlah absolut fraktur tulang rusuk yang berjumlah >2 maka dua kali lebih mungkin meninggal dunia dibandingkan pasien dengan 1-2 patah tulang rusuk. (3) Posisi anatomi patah tulang, Fraktur costa bilateral memiliki resiko kematian lebih tinggi dimana segmen flail chest menghasilkan gerak paradox yang menyebabkan pergerakan dinding dada mengarah kedalam saat inspirasi sedangkan tulang rusuk yang sehat bergerak keluar sehingga ventilasi tidak adekuat dan terjadi depresi pernafasan dan kematian. Berbeda dengan penelitian yang dilakukan Brasel et al., (2006) faktor yang paling mempengaruhi kematian adalah faktor usia ditandai dengan Injury Severity Score (ISS) jika dikaitkan dengan peningkatan terjadinya pneumonia. Analisis yang menyatakan komorbiditas mempengaruhi kematian hal ini disertai dengan faktor usia bukan karena faktor komorbiditas murni. Komorbiditas yang biasanya menyertai fraktur costa menurut penelitian adalah komorbiditas yang spesifik seperti gagal jantung kongestif, aritmia, gagal ginjal, penyakit hati, kanker metastatik dan penyakit neurologis.Pada penelitian Bulger et al dalam Wanek & Mayberry, (2004), membandingkan pasien yang berusia minimal 65 tahun keatas dengan usia 18-64 tahun dengan metode cohort pada kasus fraktur costa pada kelompok >65 tahun memiliki dua kali mortalitas dan morbiditas yang tinggi. Risiko pneumonia meningkat sebesar 27%, dan kematian meningkat sebesar 19% untuk setiap fraktur tulang rusuk tambahan pada kelompok lanjut usia.Nyeri adalah keluhan yang paling dirasakan oleh pasien dengan fraktur costa. Oleh sebab itu penanganan manajemen nyeri untuk mengontrol nyeri terus-menerus dan mencegah depresi pernafasan harus diberikan terapi yang agresif dengan pendekatan multimodalitas. Penelitian yang dilakukan oleh Peek, et.al, (2019) dengan membandingkan pemberian analgesik dengan 4 metode yaitu analgesia epidural, analgesia intravena, blok paravertebral dan blok intercostal, diperoleh hasil berdasarkan systematic review dan meta-analysis analgesia epidural signifikan mengurangi rasa sakit dibandingkan intervensi yang lain. Intervensi keperawatan sendiri menekankan pada terapi non farmakologis untuk kontrol nyeri pada pasien fraktur. Terapi nonfarmakologis dengan guided imagery dapat mengurangi intensitas dan skala nyeri pada pasien fraktur. Guided imagery mempengaruhi hampir semua fisiologis sistem kontrol tubuh yaitu pernapasan, denyut jantung, tekanan darah, tingkat metabolisme dalam sel, mobilitas dan sekresi gastrointestinal, fungsi seksual, dan bahkan respon imun (Rossman, 2000). Intervensi ini juga dapat mempercepat penyembuhan pasien dan mengurangi hari rawat inap (Forward et.al, 2015) Gambar 1. Algorithma fraktur costa (Brasel K.J, et.al, 2016).Western Trauma Association (WTA) menyatakan algorithma penanganan fraktur costa sebagai suatu observasi atau pemantauan ketat pada fraktur costa lebih dari 2 patah tulang (Brasel et.al, 2017). Berdasarkan algoritma diatas maka pasien dengan patah tulang rusuk >2 dengan usia lebih dari 65 tahun jika pada observasi kurang dari 24 jam menunjukkan peningkatan pada depresi pernafasan maka segera pindahkan ke ICU dan pertimbangkan penggunaan ventilator dan operasi rib fixaxion. Penggunaan terapi analgesia epidural digunakan untuk kontrol nyeri dilanjutkan batuk efektif, tehnik relaksasi nafas dalam dan mobilisasi dini (Brasel et.al, 2017). Analisis terkait studi literatur untuk memperkuat hasil analisis terdapat pada masing-masing artikel dibawah ini. Tabel 1. Artikel terkait faktor-faktor yang mempengaruhi terjadinya depresi pernafasan pada pasien dengan fraktur costa.Study citationMetode penelitian Desain PenelitianSampel dan Jumlah sampelHasil temuanA multidisciplinary clinical pathway decreases rib fracture–associated infectious morbidity and mortality in high-risk trauma patientsTodd,et.al,(2006)prospective cohort study Non eksperimental150 pasien dari Februari 2002-Oktober 2004 dengan > 45 tahun dan>4 patah tulang rusuk.Diperoleh hasil usia, skor keparahan cedera, dan jumlah patah tulang rusuk, jalur klinis menurunkan mekanisme hari tergantung ventilator, lama rawat inap, morbiditas infeksi, dan mortalitas dengan (interval kepercayaan 95% [CI] P<0.01).Predicting outcome of patients with chest wall injuryPressley, et.al, (2012)retrospectively reviewedNon eksperimental649 pasien (Juni 2008 hingga Februari 2010) termasuk usia, jumlah patah tulang, cedera bilateral, adanya kontusio paru, klasifikasi memar, LOS, masuk ICU, ventilasi mekanikSebuah sistem penilaian sederhana memprediksi kemungkinan bahwa pasien akan memerlukan ventilasi mekanik dan perawatan yang berkepanjangan. Skor 7 atau 8 memprediksi peningkatan risiko kematian, penerimaanke ICU, dan intubasi. Skor 5 memprediksi lama tinggal yang lebih lama dan periode ventilasi yang lebih lama. Factors Affecting Pneumonia Occurring to Patients with Multiple Rib FracturesByun & Kim., (2013).retrospectively reviewedNon eksperimentalData rekam medis 327 pasien laki-laki rata-rata usia 53 tahun dengan fraktur costa akibat kecelakaan dari Januari 2002- Desember 2008.Faktor yang mempengaruhi pneumonia pada pasien dengan fraktur tulang rusuk multipel dalam analisis multivariat termasuk usia (p=0,004), ISS (p＜0,001), dan skor tulang rusuk(p=0,038). Penggunaan antibiotik tidak berhubungan dengan kejadian pneumonia (p=0,28).Determinants of Mortality in Chest Trauma PatientsEkpe & Eyo, (2014)Retrospective and prospective Non eksperimental149 pasien dengan trauma thoraks 121 laki-laki, 28 perempuan dari Januari 2007-Desember 2011Variabel bebas, umur, jenis kelamin dan jenis cedera dada tidak terbukti berkorelasi dengan mortalitas dengan nilai P >0,05. Namun adanya cedera organ ekstra toraks terkait, skor MEWS saat masuk tinggi> 9, cedera pada interval presentasi lebih dari 24 jam, dan cedera dada yang parah ditandai dengan keterlibatan dada bilateral yang berkorelasi positif dengan mortalitas dengan nilai P <0,05.The number of displaced rib fractures is more predictive for complications in chest trauma patientsChien et.al, (2017)retrospectively reviewedNon eksperimentalJanuari 2013 -Mei 2015 diperoleh data di rumah sakit dengan total pasien 3151. Pasien yang dirawat dengan trauma dada dan patah tulang rusuk, termasuk cedera otak, limpa, panggul atau hatiJumlah patah tulang rusuk yang bergeser bisa menjadi prediktor kuat untuk berkembangnya penyakit paru-paru komplikasi. Untuk pasien dengan kurang dari tiga patah tulang rusuk tanpa perpindahan tulang rusuk dan paru-paru awal atau cedera organ lainnya, manajemen rawat jalan bisa aman dan efisien.Is the number of rib fractures a risk factor for delayed complications? Flores-Funes, et.al, (2020)Retrospective case–control studyNon eksperimentalPasien yang dirawat dengan diagnosis patah tulang rusuk antara 2010 dan 2014, diperoleh 141 pasien.Tidak ada perbedaan dalam karakteristik dasar pasien (usia, jenis kelamin dan Indeks Komorbiditas Charlson) antara kedua kelompok. Perbedaan ditemukan pada jumlah fraktur pada kelompok tanpa komplikasi p>0,05 (tidak signifikan) pada kelompok dengan komplikasi, (p=0,05) dan pada penurunan kadar hemoglobin (p=0,01). Hari rawat inap bervariasi pada setiap kelompok tetapi tanpa signifikansi statistik (p=0,11). Kesimpulan: Jumlah fraktur iga yang paling baik memprediksi munculnya komplikasi (delayed pleuro-pulmonary) dan perdarahan yang lebih besar) adalah patah tulang rusuk 3 atau lebihPredictors of mortality in patients with rib fracturesMarini, et.al, (2021) Retrospective review Non eksperimental1188 pasien patah tulang rusuk dan cedera tambahan yang dirawat selama Januari 2013-Desember 2014; 800 laki-laki dan 388 perempuan Usia, GCS, jenis kelamin laki-laki, dan Injury Severity Score (ISS) tetapi tidak jumlah patah tulang rusuk dan/atau Pulmonary contusion merupakan prediksi kematian. Peningkatan mortalitas pada pasien patah tulang rusuk dimulai pada usia 65-80 tahun tanpa peningkatan lebih lanjut. Jumlah patah tulang rusuk bukan faktor independen peningkatan mortalitas terlepas dari usia. Severe traumatic brain injury adalah penyebab kematian paling umum pada pasien usia 16-65 tahun, dibandingkan dengan komplikasi pernapasan pada pasien berusia 80 tahun atau lebih. Banyak penelitian yang telah dilakukan untuk menentukan faktor prediktor kematian pada pasien fraktur costa. Dari 7 artikel di atas terdapat berbagai bukti yang mempengaruhi kematian akibat fraktur costa dengan metode penelitian yang berbeda.Penelitian Chien, et.al, (2017) dan Flores-Funes, et.al, (2020) menunjukkan hasil yang hampir sama dimana jumlah fraktur costa yang >2 akan meningkatkan angka morbiditas dan mortalitas dikarenakan faktor komplikasi pada paru. Berbeda dengan penelitian yang dilakukan Marini, et.al, (2021) yang menyatakan jumlah dari fraktur costa tidak memprediksi peningkatan mortalitas terlepas dari usia. Menurut peneliti faktor usia menjadi prediktor utama dalam menentukan angka mortalitas pada pasien dengan fraktur costa, dimana peningkatan mortalitas pada pasien patah tulang rusuk dimulai pada usia 65-80 tahun ke atas.Penelitian yang dilakukan Todd et.al,(2006) menghasilkan hipotesa bahwa usia, skor keparahan cedera, dan jumlah patah tulang rusuk, dan implementasi jalur klinis signifikan dengan penurunan lama perawatan di unit perawatan intensif, lama rawat inap di rumah sakit, infeksi pneumonia, dan mortalitas. Maka semakin lanjut usia, tingkat keparahan yang tinggi dan jumlah patah tulang rusuk bilateral atau >2 dapat meningkatkan angka morbiditas dan mortalitas pasien dengan fraktur costa.Penelitian Pressley et.al, (2012) dilakukan dengan melakukan analisis dengan menggunakan trauma dada scoring system dimana skor >7 memprediksi peningkatan risiko kematian, penerimaan ke ICU, dan intubasi. Penilaian scoring system ini dapat digunakan untuk memprediksi kemungkinan pasien akan memerlukan ventilasi mekanik dan perawatan yang berkepanjangan sehingga dapat memperparah penyakit, menimbulkan infeksi oportunistik dan menyebabkan resiko mortalitas.Penelitian Ekpe & Eyo, (2014) menggunakan system MEWS (modified early warning signs) untuk menganalis faktor prognosis pada pasien dengan trauma dada. Sebagai variabel bebas, umur, jenis kelamin dan jenis cedera dada tidak terbukti berkorelasi dengan mortalitas dengan nilai P >0,05. Namun adanya cedera organ ekstra toraks terkait, skor MEWS saat masuk tinggi> 9, dimana interval presentasi lebih dari 24 jam dengan cedera dada yang parah ditandai dengan keterlibatan dada bilateral, berkorelasi positif pada mortalitas. Berbeda dengan penelitian sebelumnya Byun & Kim., (2013) dimana faktor umur berpengaruh pada terjadinya infeksi pneumonia dan meningkatkan angka mortilitas dengan atau tanpa diikuti tingkat keparahan pada trauma dada.Berdasarkan analisis diatas terdapat persamaan hasil penelitian dimana rata-rata metode penelitian yang dilakukan dengan menggunakan retrospective review non eksperimental. Peneliti mengamati data rekam medis dari beberapa rentang waktu dengan kriteria inklusi menderita patah tulang rusuk lebih dari dua. Namun, terdapat kriteria yang berbeda-beda pula dimana peneliti memasukkan trauma tambahan seperti brain injury dan cedera pada organ yang lain. Jumlah sampel antara penelitian satu dengan yang lain juga berbeda dari ratusan hingga ribuan data yang dianalisis. Hal ini menyebabkan hasil penelitian yang diperoleh sedikit berbeda antara satu dengan yang lain.Manajemen fraktur costa berfokus pada manajemen nyeri yang adekuat, batuk efektif, relaksasi nafas dalam dan mobilisasi dini (Brasel et al., 2017). Berdasarkan beberapa penelitian manajemen nyeri pada pasien orthopedic terutama pasca operasi adalah dengan guided imagery. The American Holistic Nurses Association menyatakan guided imagery adalah modalitas holistik yang membantu klien dalam menghubungkan pengetahuan batin mereka pada pemikiran, perasaan, dan tingkat penginderaan, mempromosikan penyembuhan bawaan mereka dengan kemampuan bersama-sama memandu klien mengatasi stres; resolusi konflik; masalah pemberdayaan diri; dan persiapan medis-bedah (Integrative & Review, 2016). Oleh sebab itu, guided imagery tepat jika digunakan pada managemen nyeri non farmakologis yang diterapkan dalam intervensi keperawatan.Dalam teori keperawatan Jean Watson tentang Transpersonal Caring mendefinisikan hubungan manusia yang bersifat caring, bersatu dengan orang lain dengan menghargai klien seutuhnya termasuk keberadaannya di dunia (Alligood, 2014). Watson menyatakan kepedulian transpersonal caring adalah dasar dari teori kepedulian manusia dimana fokus dari kepedulian transpersonal adalah pada peduli, penyembuhan, dan keutuhan, bukan pada penyakit, sakit dan patologi yang mencakup 10 faktor karatif dalam konsep utamanya (Integrative & Review, 2016). Sesuai dengan teori Watson, Guided Imagery (GI) menggabungkan kedua sains (melalui praktik berbasis bukti) dan seni (melalui aplikasi untuk berlatih) untuk mengobati rasa sakit pasien menggunakan imaginasi terbimbing dan teknik relaksasi nafas dalam. Kombinasi dengan terapi obat, GI menyediakan rezim pengobatan holistik untuk manajemen nyeri untuk menenangkan pikiran dan merilekskan tubuh mereka, memberikan kesempatan bagi klien untuk menciptakan lingkungan penyembuhan internalnya sendiri (Integrative & Review, 2016).Intervensi keperawatan untuk batuk efektif dan mobilisasi dini termasuk poin penting dalam manajemen perawatan pasien fraktur costa. Batuk efektif adalah suatu metode batuk dengan benar dan pasien dapat mengeluarkan dahak secara maksimal untuk mengeluarkan sekret dari saluran pernapasan bawah (Potter dan Perry, 2006). Mobilisasi sendiri dapat menghasilkan outcome yang baik bagi pasien seperti meningkatkan pertukaran gas, mengurangi angka Ventilator Associated Pneumoia (VAP), mengurangi durasi penggunaan ventilator, dan meningkatkan kemampuan fungsional jangka panjang (Green, Marzano, Leditschke, Mitchell, & Bissett, 2016 dalam Ananta & Fitri, 2020). Oleh sebab itu, kedua intervensi ini perlu diteliti lebih lanjut guna mengembangkan riset terkait manajemen pasien fraktur costa. SIMPULAN Pasien dengan usia lanjut dengan patah tulang rusuk atau fraktur costa biasanya menunjukkan tingkat kelemahan, multi-morbiditas, dan kompleksitas medis yang tinggi (Coary, et.al, 2020). Hal ini tentu menjadi penghambat dalam faktor penyembuhan tulang dan dapat meningkatkan angka mortalitas. Pemaparan hasil analisis menggambarkan faktor usia, cedera tulang rusuk atau costa bilateral lebih dari 2, terjadinya komplikasi dan cedera pada organ lain menyebabkan pasien harus dirawat di ruang ICU lebih lama karena resiko infeksi dan komplikasi yang dapat meningkatkan angka morbiditas dan mortalitas.Terlepas dari faktor usia, tingkat keparahan cedera dan jumlah tulang rusuk yang patah menentukan haluaran pasien yang lebih baik. Penanganan fraktur costa yang tepat yang berfokus pada kontrol kerusakan, manajemen nyeri, fiksasi seleksi, dan kualitas hidup mempengaruhi penurunan angka morbiditas dan mortalitas pasien dengan fraktur costa. Kedudukan dan peran perawat spesialis dalam tugas mengatur asuhan klien dengan kompleksitas tinggi menjadi sangat penting (Masfuri, et.all, 2019) SARAN Penelitian klinis terkait implementasi keperawatan berbasis kasus masih jarang dilakukan. Implementasi keperawatan pada pasien dengan fraktur costa terkait manajemen nyeri dan kontrol infeksi menjadi penelitian yang menarik untuk dilakukan karena hal ini menjadi indikator faktor yang mempengaruhi angka mortalitas pasien dengan fraktur costa.

Pottery production has been recognized as one of the ancient Tiv practices that have survived to this day. Therefore, whenever remains of pottery objects are identified at an archaeological site within the Tivland, they usually contain tangible information regarding the group that made and used them. This research is an ethnoarchaeological investigation of pottery tradition in Usambe community. The researcher uses ethnographic information on pottery production and usage in the area to infer about the cultural formation process, growth and advancement of the Tiv people that made and used clay wares found in fragments on the hills of Usambe. The results, however, align with the position of various scholars of Tiv tradition that the hills located in the present Usambe community are among the hills inhabited by the Tiv people during their exodus into the Benue Valley of Nigeria.

AbstractHoney and other bee products were likely a sought-after foodstuff for much of human history, with direct chemical evidence for beeswax identified in prehistoric ceramic vessels from Europe, the Near East and Mediterranean North Africa, from the 7thmillennium BC. Historical and ethnographic literature from across Africa suggests bee products, honey and larvae, had considerable importance both as a food source and in the making of honey-based drinks. Here, to investigate this, we carry out lipid residue analysis of 458 prehistoric pottery vessels from the Nok culture, Nigeria, West Africa, an area where early farmers and foragers co-existed. We report complex lipid distributions, comprisingn-alkanes,n-alkanoic acids and fatty acyl wax esters, which provide direct chemical evidence of bee product exploitation and processing, likely including honey-collecting, in over one third of lipid-yielding Nok ceramic vessels. These findings highlight the probable importance of honey collecting in an early farming context, around 3500 years ago, in West Africa.

Aims: To investigate the effect of Heavy metals on the growth of Zea mays (Z. mays) and Sorghum bicolour (S. bicolour). Study Design: Laboratory-experimental design was used in this study. Place of Study: The heavy metal polluted soil samples were collected from Crush Rock Industries Ishiagu, Ebonyi State, Nigeria, while control soil samples were obtained from the Zoological Garden of the Department of Applied Biology and Biotechnology, Enugu State University of Science and Technology. Methodology: The seeds of the two plants were collected from the Enugu State Ministry of Agriculture. The experimental setup consisted of 16 contaminated potted soils, 8 each for Z. mays and S. bicolor. Another 8 potted soils not contaminated with heavy metals served as control. Fourteen days after germination, the following growth parameters were measured (in cm); plant heights, number of leaves, stem girth, and leaf area. Results: The polluted soil sample was slightly acidic; (pH was 6.34±0.29). It had a higher cation exchange capacity (21.80±0.33), Cd (25.18±0.34), Cr (10.20±0.21), Cu (28.54±0.49), Pb (9.92±0.36), but lesser soil organic carbon (0.87±0.10). Plant samples cultivated in contaminated soil showed the least favourable vegetative growth. Conclusion: Comparing the results obtained from the control sample, it was deduced that these heavy metals have adverse effect on the vegetative growth of Z. mays and S. bicolor.

Background: The organoleptic evaluation of herbal drugs is as old as science, but the authentication of herbs on the basis of their fluorescence characteristics is difficult and sometimes impracticable because humans are limited by their sense of colour recognition.Aim: This article undertakes a computer-aided examination of some powdered herbal materials with a view to characterising them calourimetrically, thus providing a reliable organoleptic clue for their authentication, against possible misidentification.Setting: Research was conducted in Ogbomoso, Nigeria.Methods: Seventeen herbal materials (i.e. stem bark, root/root bark, vines, fruit calyx, leaf sheath and seed) used for two traditional powdered drugs were collected and pulverised into powders. Their colours were digitised by scanning the surface of the powders in petri dishes using a CamScanner installed on a Samsung Galaxy Tablet 10.1 Model 7500, and were qualitatively and quantitatively analysed by uploading the images into the online Cool Hypertext Preprocessor (Cool PHP) software tool, setting the number of colours at five, thus giving consideration to only five dominant colour shades in each image, all expressed as hexadecimal codes. The codes were uploaded into Chir.ag/art, another online tool, to read off the colour names. The relative mean percentage, frequency and relative colour intensity (RCI) of each colour shade were calculated, and the colour with the highest RCI was taken as the first or typical colour of each herb.Results: Nine of the 62 colours observed, namely Lucky, Sandrift, Cannon Pink, Potters Clay, Mandalay, Ferra, Domino, Russet and Roti, were highly restricted in distribution, each being the first or typical colour in only one species of the herbs (i.e. Enantia chlorantha, Garcinia kola, Hibiscus sabdariffa, Khaya senegalensis, Sarcocephalus latifolius, Sorghum bicolor, Theobroma cacao, Uvaria chamae and Zanthoxylum zanthoxyloides respectively). These colours were therefore substantially diagnostic of those herbs. Another nine colours among the most frequently observed colours and the number of species that had them were Pesto (9), Shadow (8), Driftwood (8), Barley Corn (5), Domino (4), Roman Coffee (4), Cape Palliser (4), Himalaya (4) and Husk (4); these were less diagnostic of the herbs in question. Based on the distribution of these colours, a diagnostic PHP colour chart was constructed for the authentication of the powdered medicinal herbs.Conclusion: Powders of the 17 medicinal herbs analysed have been characterised colourimetrically with each species being unambiguously diagnosed. The study has therefore circumvented the subjectivity of the human sense of colour recognition in medicinal herb authentication.

Introduction: Despite the efforts of Governments and non-governmental organizations in sponsoring ceramic water purifier (CWP) filter project across the globe, some rural communities in Ekiti State, Nigeria are yet to benefit from it. One of the major technical difficulties hindering the making of CWP filter cells in many places was the adaptation to the sand, clay and sawdust mixture necessary to obtain the correct filter properties. Aim: In this study, some salient properties of clay from orudi, arade and oturo deposits at Isan Ekiti were assessed in the light of their usefulness for making the ceramic water filter cells. Methodology: The particle size distribution analysis and consistency tests were carried out on the crude clay. Also the shrinkage, effects of percentage constituents of burnout on porosity, filtration rate and quality of filtrate were measured, using standard methods. Results: Results show that arade has the appropriate technical properties for making the filter cell. The chosen clay sample has its deposit less than 2 kilometers to the point of making. About 56% of its particles are less than 0.075mm equivalent spherical diameter (ESD). A composition of ratio 50:50 by volume mixture of clay to sawdust has the porosity of 54. 55% while that of ratio 40:60 is 55.56%. Samples made of these batches were capable of reducing the water turbidity Neflometric Turbidity Unit (NTU) of contaminated water by 95%. The 50:50 samples have the higher capacity of reducing total coliform count by 50.28% as against 25.07% for 40:60 samples. Conclusion: Given appropriate facilities and training, with the abundant clay at arade deposit, the pottery center is a place where CWP filter cell factory could be established.

Screen house trials for the assessment of Neem-fortified cassava peels for control of plant-parasitic nematodes and yield improvement of sugarcane (Saccharum officinarum) were conducted in Moor plantation, Ibadan, Southwest Nigeria. Cassava peel powder (CPP) solely and in combination with Neem Leaf Powder (NLP) or Neem Seed Powder (NSD) at 100gCPP/10 Litre soil, 90gCPP+30gNSP/10 Litre soil, 80gCPP+20gNSP/10 Litre soil, 70gCPP+30gNSP/10 Litre of soil, 90gCPP+10gNLP/10 Litre soil, 80gCPP+20gNLP/10 Litre soil, 70gCPP+30gNLP/10 Litre soil were incorporated into potted naturally infested soil in the screen house, at 14 d before planting. All treatments significantly (p<0.05) reduced plant-parasitic nematode population. Soil treatment with Cassava Peel Powder in combination with Neem Leaf Powder at 70gCPP+30gNLP/10 Litre of soil recorded the most effective control for soil and root nematodes associated with sugarcane in the two screen house trials. The soil amendment also supported the good vegetative growth and yield of sugarcane, which is an indication of its capability to improve soil fertility.

Pot experiments were conducted at the Faculty of Agriculture, Kogi State University, Anyigba, Kogi State in the Southern Guinea savannah ecological zone of Nigeria to evaluate the influence of seed size on plant performance with reference to seedling emergence, seedling growth, development and yield components and yield of groundnut (Arachis hypogea). The treatment consisted of three different seed sizes: small, medium and large seeds apportioned to a Randomized Complete Block Design (RCBD) with ten replications. For seed size, the seeds were initially graded into small, medium and large seeds based on visual assessment for length and diameter and from each group 100-seed weight was determined thus 100-seed weight became the parameter for measuring seed size as used in this experiment. The analyzed data showed no significant effect of seed size on groundnut canopy height, leaf number, leaf area, stem girth, days to first flower, number of pods / plant, pod weight, and shelling percentage, but significantly influenced mean days to seedling emergence, days to 50 percent flowering, 100-seed weight and taproot length. The significant effect of seed size on days to seedling emergence, days to 50 percent flowering, 100-seed weight and taproot length could significantly influence farmers’ opinion in the choice of seeds used in planting a field; as this could determine crop maturity, grain yield/ha while length of tap root could affect depth of root forage for nutrients and water, thus crop survival. Despite the non-significant effect of the treatment (seed size) on most parameters investigated, generally crop performance increased with seed size and vice versa, thus sowing of larger seeds is recommended for better groundnut performance.
