Abstract:

Currently, thermal investigation in hybrid colloidal liquids is noteworthy. It has applications in medical sciences, drug delivery, computer chips, electronics, the paint industry, mechanical engineering and to perceive the cancer cell in human body and many more. Therefore, the study is carried out for 3D magnetized hybrid nanofluid by plugging the novel Cattaneo–Christov model and thermal radiations. The dimensionless version of the model is successfully handled via an analytical technique. From the reported analysis, it is examined that Graphene Oxide-molybdenum disulfide/C2H6O2-H2O has better heat transport characteristics and is therefore reliable for industrial and technological purposes. The temperature of Graphene Oxide GO-molybdenum disulfide/C2H6O2-H2O enhances in the presence of thermal relaxation parameter and radiative effects. Also, it is noted that rotational velocity of the hybrid nanofluid rises for stronger magnetic parameter effects. Moreover, prevailed behavior of thermal conductivity of GO-molybdenum disulfide/C2H6O2-H2O is detected which shows that hybrid nanofluids are a better conductor as compared to that of a regular nanofluid.

Abstract:

Abstrak Tren keamanan pangan menjadi isu sensitif dalam industri pangan saat ini. Pertanian organik dapat menjadi alternatif solusi karena memiliki keseimbangan lingkungan, kesehatan, dan kebermanfaatan bagi petani lokal. Namun, tingginya harga produk serta skala produksi yang masih rendah menjadi faktor yang membatasi pertumbuhan pasar pangan organik di dalam negeri. Penelitian ini bertujuan menganalisis perilaku konsumen pangan organik, menganalisis saluran pemasaran dan memformulasikan alternatif saluran pemasaran pangan organik dalam negeri. Pengambilan sampel dilakukan secara purposive dimana kriteria responden adalah mereka yang mengetahui pangan organik dan berdomisili di lima kota besar pulau Jawa dan Bali. Survei saluran pemasaran dilakukan di Jakarta dan Jawa Barat dengan mewawancarai aktor-aktor di setiap rantai nilai. Hasil penelitian menunjukkan peluang pasar pangan organik cukup besar, karena umumnya responden telah menyadari bahwa pangan organik baik untuk kesehatan. Konsumen pangan organik saat ini termasuk kelompok middle class segment berusia 20-50 tahun, pekerja kantoran dan berpenghasilan di atas Rp 9 juta. Bagi konsumen, label sertifikasi pangan organik lebih penting dari merek. Saluran pemasaran organik sangat bervariasi. Pada pasar B2C pemanfaatan digital marketing dapat meminimalisir risiko finansial petani organik. Sementara pasar B2B dapat dioptimalkan melalui kerjasama perhotelan, restoran, kafe, rumah sakit, dan industri pengolahan makanan sehat, serta didukung kebijakan pemerintah yang selaras. Kata Kunci: Pangan Organik, Perilaku Konsumen, Saluran Pemasaran, Negara Berkembang Abstract The trend of food safety is a sensitive issue in the food industry today. Organic agriculture can be an alternative solution because it has a right balance in terms of the environment, health and benefits for local farmers. However, high prices for organic products and low production scale limit the growth of the domestic organic food market. This research aims to analyze organic food’s consumer behavior, analyze the existing marketing channels and formulate alternative marketing channels for the domestic organic food supply chain. Sampling was carried out by purposive sampling method in which the criteria for respondents were those who know about organic food and live in five big cities in Java and Bali. The marketing channel survey was conducted in Jakarta and West Java by interviewing each actor in the value chain. The results showed that organic food’s market opportunity was quite large, because the respondents were generally aware that organic food was good for health. Organic food consumers are currently included in the middle-class segment, aged 20-50 years, office workers, and income more than IDR 9 million a month. For consumers, certification labels are more important than brands in organic food. On the one hand, organic marketing channels still vary widely. In the B2C market, the use of digital marketing can minimize the financial risks of organic farmers. On the other hand, the B2B market can be optimized through cooperation in hotels, restaurants, cafes, hospitals, and the healthy food processing industry, supported by government policies.

Abstract:

In 1960s, Indonesia experienced serious rice insufficiency and was one of the largest rice importing countries. The government was encouraged to achieve rice self-sufficiency, i.e. implementing the green revolution (GR) technology through promoting modern agricultural inputs adoption. GR had helped Indonesia to achieve rice self- sufficiency in 1984. However, such technology deals with some problems, e.g. environmental destruction and farmers’ dependence on agrochemical industry. Many consider organic farming system is the solution to address this issue as its practice offers the best way toward sustainable food production and resources use. Demand for organic rice is expected to increase in the future along with the population and income growth. However, prospect of organic rice farming is still uncertain as its adoption is very low. The main challenge is farmers’ unease on yield reduction. Other crucial problems are lack of technical know-how and government supports as well as increase in costs of land conversion and chemical contaminations from conventional farming. It is necessary to conduct more in-depth studies on the factors influencing farmers’ willingness to adopt organic farming. It will be useful for the government to design appropriate strategies and policies to accelerate organic rice farming adoption. AbstrakPada 1960-an, Indonesia mengalami kekurangan beras dan termasuk salah satu pengimpor beras terbesar di dunia. Pemerintah saat itu memprioritaskan pemenuhan beras dengan target swasembada dengan berbagai upaya, seperti penerapan teknologi revolusi hijau (RH) melalui penggunaan input pertanian modern. RH terbukti membuat Indonesia mencapai swasembada beras pada tahun 1984. Namun, teknologi tersebut juga telah menyebabkan dampak negatif, terutama kerusakan lingkungan dan petani sangat bergantung pada industri agro- kimia. Beberapa kalangan menganggap sistem pertanian organik adalah solusi untuk mengatasi masalah ini. Pertanian organik menawarkan cara terbaik untuk produksi pangan dan penggunaan sumber daya secara berkelanjutan dan ramah lingkungan. Permintaan beras organik diperkirakan akan meningkat di masa mendatang seiring dengan pertumbuhan penduduk dan pendapatan. Adopsi pertanian organik masih sangat lambat. Tantangan utama pertanian padi organik adalah kekhawatiran anjloknya hasil panen ketika melakukan konversi. Permasalahan lainnya adalah kurangnya pengetahuan teknis dan dukungan pemerintah, mahalnya biaya konversi dan kontaminasi bahan kimia dari pertanian konvensional. Diperlukan penelitian yang lebih mendalam tentang faktor-faktor yang memengaruhi petani untuk mengadopsi pertanian organik. Dengan demikian pemerintah dapat merancang strategi dan kebijakan yang tepat untuk mempercepat adopsi pertanian padi organik.

Abstract:

The Chilean organic wine industry has comparative advantages with Europe and the United States because of its ideal environmental conditions, resulting in low presence of pests and diseases and lower production cost. Additionally, the wine production process is one of the strictest in the world, so the transformation from conventional to organic wine production can be achieved economically. A survey was conducted of 32 Chilean organic vineyards during 2004. The survey included 18 questions about total surface area, certification, varieties, final market, etc. The survey covered 95% of the land under organic wine production, with a total of 1892 ha, of which 1088 ha have organic certification and 804 ha are in transition to organic production. The major vineyards and valleys with organic wine production are Maipo (33.7%), Colchagua (17.2%), El Maule (14.0%), Curicó (9.9%), and Cachapoal (8.8%). The most important organic red varieties currently under production are `Cabernet Sauvignon' (40.9%), `Merlot' (15.1%), `Syrah' (9.1%), `Carmenere' (7.3%), `Malbec' (3.3%), and `Pinot Noir' (2.5%). The white varieties are `Sauvignon Blanc' (6.4%), `Chardonnay' (5.1%), and `Semillón' (1.0%). The potential for the organic wine industry in Chile is tremendous since organic vineyards represent only 2% of the total vineyard industry.

Abstract:

Inceptisol is one type of land order that is widely spread in Indonesia. Its distribution reaches approximately 52.0 million hectares (Kasno, 2009). Inceptisol is widely used as an intensive farm because its management is less precise, then most Inceptisol fertility rate becomes low. This is often shown by soil acidity, organic matter content, and low nitrogen, to improve such properties one of which can use the addition of organic matter. The problem that often arises is the high cost of organic fertilizer. Seaweed industry waste is a source of organic material that has not been widely utilized. Of the total raw materials processed, there is 65 to 70 percent of industrial products produced by the seaweed industry waste every day (Mandela. 2010). Usually these side products are only left to accumulate at the landfill site. Seaweed industry waste has the potential to be used as a source of soil organic matter because the organic material content of products of seaweed industry reaches 6.4% (Afif, 2011). The addition of nutrients to the application of inorganic materials is considered as an alternative step in increasing crop productivity. Based on the description above, it is necessary to conduct research to utilize the waste of seaweed industry, to get high corn production in Inceptisol. The objectives of this research are: (1) To know the effect of seaweed industrial solid waste on soil chemical properties Inceptisol and (2) growth of maize. The research was conducted in the greenhouse, while for the analysis of soil samples and the waste of seaweed industry was conducted in soil chemistry and soil physics laboratory, Department of Soil Science, Faculty of Agriculture, Brawijaya Universities. The study was conducted from May to August 2016. The soil samples used in this study were taken from Kemirisewu village, Pandaan sub-district, Pasuruan district at a depth of 0-20 cm. The waste of seaweed gel plant is obtained from PT. HAKIKI DONARTA, Pandaan Sub-district, Pasuruan Regency. The basic fertilizers used are Urea, KCl, and TSP. Maize seeds used as indicator plants are hybrid varieties of BISI-2 maize. This study used Completely Randomized Design (RAL) with 4 (four) treatments and 3 (three) replications. Addition of solid waste of seaweed with the dosage of 15 Mg/ha, increased of soil acidity and C-Organic content, besides also can increase Phosphorus and Potassium content available, Nitrogen, Phosphorus, and Potassium plant uptake, and the best growth of maize.

Abstract:

The palm oil industry is one of the major agro-based industries in Malaysia whose production accounts for more than 90% of the world export. The industry, however, also generates enormous quantities of liquid waste with high organic load causing serious pollution problems. In view of the high level of organics, anaerobic pretreatment is usually practised prior to aerobic breakdown. Most of the anaerobic digesters installed at the mills are currently operated under mesophilic conditions. However, the inherently high temperature of the effluent suggests that thermophilic digestion would bring about a much more effective system. This paper reports on results obtained from a pilot plant study on thermophilic anaerobic contact digestion of palm oil mill effluent which has been conducted and includes a microbiological study associated with the investigation.

Abstract:

Southern organic fruit production is limited by a lack of regionally appropriate, scale-neutral, and market-focused research and technology. There has been limited research, outreach, and cooperation among universities on organic fruit crops in the southern region. Organic research and outreach activities, based on producer input, must be focused on the most limiting areas of the organic system in order to allow southern producers to receive the economic and environmental benefits that organic agriculture can provide. With funding from USDA-SARE and USDA-SRIPMC, researchers at the University of Arkansas have collaborated with scientists, extension specialists, growers, and representatives of the organic industry in Arkansas, Georgia, Kentucky, North Carolina, South Carolina, and Tennessee to create a Southern Region Organic Fruit Working Group (SROFWG). The SROFWG conducted in-state focus group meetings through which barriers to production and marketing, and opportunities for organic fruit in the region were identified. Prioritized research and outreach needs that were identified in the focus groups included use and understanding of organic fertilizers and nutrient management; methods, knowledge and awareness of pest disease and weed control including orchard floor management; information on transition to organic; consumer awareness and market development and the economics of organics. The planning activities of the SROFWG support the development and submission of grants for cooperative and collaborative research and outreach programs to sustain and expand organic fruit production in the southern region.

Abstract:

Abstract The aim of this study was to investigate the influence of residual glycerine (5 and 10% w/w) from the biodiesel industry, used as a co-substrate, on biogas production from maize silage. The experiments were conducted in a laboratory-scale, single-stage anaerobic digester at 39ºC and hydraulic retention time (HRT) of 60 d. Addition of 5% residual glycerine caused organic load rate (OLR) to increase to 1.82 compared with 1.31 g organic dry matter (ODM) L-1d-1 for maize silage alone. The specific biogas production rate and biogas yield were 1.34 L L-1d-1 and 0.71 L g ODM-1 respectively, i.e. 86% and 30% higher than for maize alone. Increasing the residual glycerine content to 10% increased OLR (2.01 g ODM L-1d-1), but clearly decreased the specific biogas production rate and biogas yield to 0.50 L L-1d-1 and 0.13 L g ODM-1 respectively. This suggested that 10% glycerine content inhibited methanogenic bacteria and organics conversion into biogas. As a result, there was accumulation of propionic and valeric acids throughout the experiment.

Wakah Village Community Empowerment Through Utilization of Cassava Peel Waste (Manihot esculenta)ABSTRACTDesa Wakah has cassava and several horticultural products as its main commodity. There is a homemade production "Gethuk Anyar" which produces “Gethuk Singkong”, a kind of traditional foods, on a large scale. As the consequences, this production brings cassava peel waste approximately up to 80 kg per day. This waste has not been used optimally, thus it causes foul odors, garbage buildup, and a polluted environment as well. Based on that problem, the researchers conduct some training programs on the utilization of cassava peel waste into several products namely: compost, liquid organic fertilizer, and fermented food for animal. This activity was carried out between March and April 2020 with 30 participants from the Karang Taruna (youth) group. Those programs consist of providing materials, facilitating discussions, and conducting workshops with a participatory approach. The result of the programs shows that Wakah community was able to utilize cassava peel waste into three agricultural supporting products; those are: compost, liquid organic fertilizer, animal fermented food. In addition, the value of participants’ understanding and skill in processing the waste was up to 85% and it meets the standard research target. Moreover, the community is also committed to develop products independently. The synergy between Wakah community, the local government and the industry workplace is expected to increase community empowerment activities in processing cassava peel waste into some useful products.Key Words: fermentation, cassava peel, organic fertilizer.

Abstract:

ABSTRACTSurabaya River is a source of raw water for the needs of the community in Surabaya and its surrounding areas, including for industrial and the Surabaya water supply company. Along with the rapid growth of settlements and the development of the industrial sector, the Surabaya River pollution level has increased so that the quality of the water does not meet the quality standards required as raw water for drinking water. The most potential parameter that causes the level of pollution is organic pollutants. The concentration of some water quality parameters including organic pollutants in the Surabaya River has exceeded class I water quality standards based on Government Regulation (PP) No. 82 of 2001, namely for allotment of raw water for drinking water. The purpose of this study was to improve the raw water quality such as parameters of suspended solids (TSS), organic substances, detergents and manganese (Mn) through the application of biofilter technology. The study was conducted by operating a biofilter pilot plant consisting of a lamella-type settling tank and a biofilter reactor filled with wasp-type nesting media. The results showed that the biofilter process used can reduce the concentration of TSS, organic matter, detergents and Mn in raw water. In general, the longer the hydraulic residence time (HRT) in the biofilter pilot plant, the greater the efficiency of removing TSS, organic matter, and detergent in raw water. The experiments results at the conditions of the shortest total HRT of 81 minutes, including HRT of 36 minutes in the settling tank and HRT of 45 minutes in the biofilter reactor, could obtain TSS removal efficiency of 46.92%, 15.97% for organic matter, and 55% for detergent, where the concentration of these parameters meets the quality standards for drinking water.Keywords: biofiltration, HRT, drinking water, water qualityABSTRAKSungai Surabaya merupakan sumber air baku untuk kebutuhan masyarakat di wilayah Surabaya dan sekitarnya, termasuk untuk kebutuhan industri dan air baku PDAM kota Surabaya. Seiring pesatnya pertumbuhan pemukiman dan perkembangan sektor industri, mengakibatkan tingkat pencemaran Sungai Surabaya semakin tinggi sehingga kualitas airnya tidak memenuhi ketentuan baku mutu yang dipersyaratkan sebagai air baku air minum. Parameter yang paling potensial menyebabkan tingkat pencemaran tersebut adalah polutan organik. Konsentrasi beberapa parameter kualitas air termasuk polutan organik di sungai Surabaya telah melebihi baku mutu air kelas I berdasarkan Peraturan Pemerintah (PP) No 82 tahun 2001, yakni untuk peruntukan air baku air minum. Tujuan dari penelitian ini adalah untuk melakukan peningkatan kualitas air baku seperti parameter padatan tersuspensi (TSS), zat organik, deterjen dan mangan (Mn) melalui penerapan teknologi biofilter. Penelitian dilakukan dengan mengoperasikan pilot plant biofilter yang terdiri dari bak pengendap tipe lamella dan reaktor biofilter yang diisi dengan media plastik tipe sarang tawon. Hasil penelitian menujukkan bahwa proses biofilter yang digunakan dapat menurunkan konsentrasi TSS, zat organik, deterjen dan Mn di dalam air baku. Secara umum semakin lama waktu tinggal di dalam pilot plant biofilter, efisiensi penghilangan TSS, zat organik, dan deterjen di dalam air baku semakin besar. Hasil percobaan pada kondisi total waktu tinggal terpendek (total HRT) 81 menit, meliputi HRT di bak pengendap 36 menit dan HRT di reaktor biofilter 45 menit, didapatkan efisensi penghilangan TSS 46,92 %, zat organik 15,97 %, dan deterjen 55 %, dimana konsentrasi parameter-parameter tersebut memenuhi baku mutu untuk air minum.Kata kunci: biofiltrasi, HRT, air minum, kualitas air

Abstract:

ABSTRACT Organic waste from food and beverage can be degraded by microbes. The sludge from food industries still contains nutrition such as carbohydrates, proteins, and fats. One attempt to process and utilize the sludge is to reuse it as the growth medium for Black Soldier Fly (BSF) maggot, which is known to have high nutritional value for fish or livestock feed. This research used ice cream industrial sludge as maggot feed. The problem of using the ice cream industrial sludge for maggot feed is the odour that pollutes the environment. Biosorption is a technique for deodorizing waste sludge using organic materials. This research was conducted to obtain the most effective ratio of biosorbents from fermented manure (PKN), compost (K), and calcium carbonate animal shells (Ca) to remove odours by reducing N-ammonia and sulfide in ice cream industrial sludge using biosorption techniques. The effect of biosorbent used for BSF (Black Soldier Fly) maggot feed on maggot growth was also observed. The most effective biosorbent composition in reducing odor, N-ammonia, and sulfide of the sludge was K:Ca:Sludge (1:1:3) with adsorption time of 48 hours and the percentage reduction of 85.0%. However, the number and size of maggot with PKN:K:Sludge (1:1:3) growth media were higher than K:Ca:Sludge (1:1:3). The ratio of PKN:K:Sludge (1:1:3) was proven to increase maggots' growth to provide benefits for farmers in increasing maggot production both in number and size. Keywords: Black Soldier Fly maggot, biosorbent, biosorption, organic waste, waste deodorization ABSTRAK Limbah organik dari industri makanan dan minuman dapat didegradasi oleh mikroba. Sludge dari limbah industri makanan masih mengandung bahan-bahan nutrisi seperti karbohidrat, protein, dan lemak. Salah satu usaha untuk mengolah dan memanfaatkan sludge tersebut adalah dengan menggunakannya kembali sebagai media pertumbuhan maggot Black Soldier Fly (BSF) yang diketahui sangat tinggi kandungan nutrisinya untuk bahan pakan ikan atau ternak. Penelitian ini menggunakan limbah organik dari industri es krim sebagai pakan maggot. Masalah yang ditimbulkan dari pemanfaatan limbah sludge industri es krim untuk pakan maggot adalah bau yang mengganggu dan mencemari lingkungan. Biosorpsi merupakan salah satu cara untuk menghilangkan bau (deodorisasi) pada limbah sludge. Penelitian ini bertujuan untuk mendapatkan rasio biosorben pupuk kandang fermentasi (PKN), kompos (K) dan kalsium karbonat dari cangkang hewan (Ca) yang paling efektif dalam menghilangkan bau dengan menurunkan N-amonia dan sulfida pada limbah sludge industri es krim melalui teknik biosorpsi. Pengaruh biosorben yang digunakan untuk pakan maggot BSF juga diamati terhadap pertumbuhan maggot. Rasio K:Ca:Sludge (1:1:3) dengan waktu adsorpsi 48 jam merupakan rasio yang lebih efektif untuk menurunkan bau, N-amonia, dan sulfida pada sludge dengan presentase penurunan 85,0%. Akan tetapi, jumlah dan ukuran maggot hasil panen dengan media pertumbuhan PKN:K:Sludge (1:1:3) lebih besar dibandingkan dengan K:Ca:Sludge (1:1:3). Rasio PKN:K:Sludge (1:1:3) terbukti dapat meningkatkan pertumbuhan maggot sehingga memberi manfaat bagi peternak dalam meningkatkan produksi maggot baik secara jumlah dan ukurannya.

Abstract:

In this paper, the treatability of strong wastes originating from an organic chemicals industry was studied. Literature data were evaluated to assess the applicability of conventional and advanced methods of treatment to highly concentrated wastewaters. A detailed treatability study was conducted on the wastewater, which was provided from a small-scale polyester manufacturing plant. The manufacturing process involved only esterification reactions, generating a wastewater with a COD content of over 200,000 mgl−1. The applicable treatment methods to be tested were determined as biological treatment of activated sludge process with low organic loading and chemical oxidation with H2O2. Results of the biological treatability study indicated that 80% COD removal could be obtained with 10 days retention time, provided that the system was fed with a 1/100 diluted raw wastewater. Chemical oxidation of raw wastewater with H2O2 in acid conditions and using ferric chloride as catalyst yielded 70% COD removal. However, the dosage required to obtain this efficiency was about 1 kg H2O2 per m3 of wastewater. With these applications the wastewater was treated to yield a COD of lower than 2000 mg/l. Results of the study were discussed and evaluated considering complexity and cost of treatment.

Abstract:

Introduction Organic solvents are chemically different compounds with one common feature: they dissolve fats, oils, resins, cellulose acetate and cellulose nitrate, which makes them widely used in industry. Most often organic solvents are used in paint and lacquer industries, in production of pesticides, plastics, explosives, rubber, cellulose, air conditioners, in pharmaceutical industry and in leather industry. The aim of this research was to analyze the working environment and professional hazards in paint and lacquer manufacturing industry and evaluate effects of chronic exposure to mixture of organic solvents on nervous system of exposed workers. Methodology The exposed group consisted of 50 workers professionally exposed to these noxae, while the control group consisted of 30 workers who have never been exposed to these noxae. Results Examination of working environment in departments of paint and lacquer manufacturing revealed presence of white spirit and toluene above allowed levels. Exposed workers more frequently complained of fatigue, hand numbness, enhanced excitation, and concentration difficulties, forgetfulness and headaches, than workers from the control group. Electroneurographic examination of n. medianus showed reduced motor and sensitive conduction velocity among exposed in comparison to workers from the control group. Reduced motor and sensitive conduction velocity was correlated with duration of exposure to these noxae. Terminal latency of n. medianus was statistically, significantly longer in the exposed group than in the control group. Workers in the exposed group have statistically significantly longer reaction time in response to acoustic and visual stimuli. Discussion Segmental demyelination and axonal degeneration, as forms of damage to peripheral nerves, were identified as responsible for peripheral neuropathy associated with occupational exposure to organic solvents. Conclusion Results of this study show possible neurotoxic effects of noxae detected in the phase of analysis of working conditions and working environment of examined workers.

Abstract:

Introduction. Work in pharmaceutical-chemical industry is characterized by exposure to numerous hazards, both physical (microclimate, illumination, noise) and chemical (organic solvents). Organic solvents can cause damage to many organic systems and have carcinogenic, teratogenic and mutagenic effects. Objective. The aim of this study was to analyze patterns of chronic morbidity of workers employed in pharmaceuticalchemical industry during 2002. Method. The study was conducted in the pharmaceutical- chemical industry "Zdravlje" Leskovac in 2002. A total of 143 workers in workplaces with special working conditions - exposed to chemical hazards as well as 40 workers from control group took part in the study. The physical examinations of the participants were performed at the Department of Occupational Health in Health Center, Leskovac. Results. Heart diseases were the most frequent both among exposed workers (17.8%) and in control group (33.3%). Respiratory diseases were at the second place (16.9% in the exposed group, and 7.4% in control group). Arterial hypertension was diagnosed in 14.7% workers occupationally exposed to hazards, and in 12.5% workers from control group (p>0.05). Chronic bronchitis was diagnosed in 17.5% of the exposed workers and in only 5.0% of controls (p>0.05). The highest prevalence of diseases in both groups was observed among workers aged 40-49 years, with 20-29 years of exposure working time. 73.4% of the exposed workers and 85% of control workers were capable of work (p>0.05). Conclusion. Workers occupationally exposed to hazards in pharmaceutical-chemical industry have higher prevalence of various diseases compared to non-exposed workers, which can be the result of work, working conditions and work activity. Preventive measures should be directed towards the decrease of occupational hazards and unfavorable working conditions and increase of work protection. Regular physical examinations of workers are of prime importance for the prevention of occupational morbidity, traumatism and invalidity. .

Abstract:

PurposeThis study investigates organic wine consumption and analysed the motives, preferences and basic characteristics of German consumers of organic and non-organic wines.Design/methodology/approachThe comparative study is based on data from a representative survey conducted with 2,000 consumers in Germany. Two segments of wine drinkers were created according to their consumption of organic wine. Consumers of organic and non-organic wine were compared by analysing the differences in wine-related behavioural factors and socio-demographic variables.FindingsThe study reveals that consumers of organic wine differ significantly from those who do not drink organic wines. Socio-demographic factors (e.g. age and social class) and behavioural attributes (e.g. frequency of wine consumption and involvement with and preference for other organic products) demonstrate the differences between the two consumer groups.Originality/valueTo our knowledge, no findings exist to date regarding differences between consumers of organic wine and consumers of non-organic wine. Therefore, these results fill a research gap and provide valuable inputs both to the wine industry as well as to the scientific community dealing with organic food preferences.

Abstract:

A series of batch treatability screening tests were conducted to identify technologies suitable for removal of ethylenediamine (EDA) and aquatic toxicity in a wastewater discharge from a synthetic fiber plant. Air stripping, cation exchange resin, activated silica, macroreticular resin, granular activated carbon and bio-hydrolysis were evaluated. Only cation exchange resin and bio-hydrolysis reduced effluent toxicity to the required limit. Continuous flow bench-scale activated sludge treatability tests were conducted over a four month period under simulated warm and cold weather operating conditions. The results confirmed that activated sludge treatment alone could consistently provide greater than 95 percent BOD reduction and complete EDA hydrolysis, nitrification and toxicity reduction. Toxicity reduction could be accomplished at high organic loading (F/M > 1.0/day) but hydrolysis of EDA caused an effluent NH3-N concentration of greater than 300 mg/L. A lower organic loading (F/M <0.30/day) was therefore selected to provide nitrification for compliance with the 25 mg/L NH3-N pretreatment limit. Alternatively, a high rate activated sludge system (F/M > 1.0/day) coupled with high pH air stripping of ammonia was considered in “desktop” evaluations. A detailed process design and cost estimate were developed.

Full text

Abstract:

Regulation of organic farming allows the use of a limited range of fertilisers and soil amendments to meet nutritional needs of the plants. Before advocating alternative strategies for fertility management, performance should be evaluated. An open field experiment was conducted to study the effects of different fertilisation scenarios on tomato (Solanum lycopersicum Mill, cv. San Marzano) production and soil chemical properties. Fertilisation scenarios were based on combinations of amendments (composts and biochar) with organic and/or mineral fertilisers to balance plant nutrient requirements. Amendments were produced from agricultural and food-industry wastes available in the region. Most of the soil parameters did not vary by the end of experiment; only available phosphorus slightly increased in the treatments where organic fertilisers were applied. All treatments significantly increased yields over control and biochar alone. Different compost types showed promising results for tomato production and quality, whereas biochar did not. The study demonstrated that recycling of nutrients from on-farm or food-industry wastes might be a good strategy to increase productivity and sustainability of Mediterranean organic agriculture when integrated fertility management is adapted. However, more studies are needed to evaluate their effect in long-term experiments.

Abstract:

The accuracy of soil and plant analytical results are occasionally called into question by laboratory clientele. Although laboratories generally conduct internal quality assurance procedures, there are few external performance testing programs for the industry. In 1994, a proficiency testing program was initiated for soil and plant samples for agricultural laboratories in the western United States to provide an external quality control for the lab industry. The program involves the quarterly exchange of soil and plant samples on which soil salinity, soil fertility, and plant nutrition analyses are conducted. One hundred laboratories are annually enrolled in the program from 24 states and Canadian provinces. Results of 3 years of the program indicate soil nitrate, soil pH, extractable potassium, soil and organic matter are reproducible within 10% between laboratories. Soil-extractable phosphorus (by five methods), soil-extractable boron, and soluble chloride were only reproducible within 15% to 20% between laboratories. Plant nitrogen and phosphorus results were consistent across samples, laboratories, and methods. Variability in plant nitrate increased with decreasing tissue concentrations. Overall accuracy and precision of reported results, based on the use of NIST certified reference botanical samples, were excellent for N, P, K, Ca, and Cu. Generally, for any given analysis, the results of ≈10% of the laboratories exceed two standard deviations from the mean. Overall, significant improvement was noted in the laboratory industry proficiency through the course of the program.

Abstract:

Herein, the benefits which extrusion can provide for the automated continuous synthesis of organic compounds are highlighted. Extrusion is a well-established technique that has a vital role in the manufacturing processes of polymers, pharmaceuticals and food products. Furthermore, this technique has recently been applied to the solvent-free continuous synthesis of co-crystals and coordination compounds including metal-organic frameworks (MOFs). To date, a vast amount of research has already been conducted into reactive extrusion (REX), particularly in the polymer industry, which in many cases has involved organic transformations, however, it has not received significant recognition for this. This review highlights these transformations and discusses how this previous research can be applied to the future of organic compound manufacture.

Abstract:

Amelioration and/or reclamation of saline and non-saline soils is based on the application of high quantities of agrochemical products or high volumes of water, which causes an injury in soil or downward displacement of nutrients to the lower layers in soils. Research was conducted to evaluate the effect of application of citric industry waste on saline and non-saline soil. The waste has an electrical conductivity (EC) of 2.7 dS/m and pH of 3–4.2, 35% is organic material that is readily decomposed. This experiment was carried out on field conditions using applications of three different volumes, T1 = 3200, T2 = 6400, and T3 = 9600 m3·ha–1·m–1 and a control, no-waste, (T0), using just irrigation water (EC = 2.5 dS·m–1). The same treatments were added to non-saline soil. Effect of citric industry waste application in both saline and non-saline soils was similar. In all the treatments, EC was decreased with respect to T0 and soil before application (BA), the largest decrease was found in T3. pH decreased in the top soil layer much more than in the bottom layers. Ions were decreased in all soil profile. Organic matter (OM) was increased in the profile in treatment T1 with respect to treatment T0, as well as in the top soil layers in T2 and T3, but no changes were detected in the remainder of the layers in treatments T2 and T3. We can suggest that the waste studied can be used in the amelioration of saline and non-saline soils.

Abstract:

World experience indicates that the problems of ensuring sustainable development of agriculture have become an urgent need, therefore, the concepts of traditional technology for cultivating crops should be substantially revised not only from the standpoint of environmental management, but also to improve the economic situation in the industry. Greening of agriculture contributes to natural restoration of soil fertility, maintaining the balance of nature, on which agricultural economy largely depends. A growing quantity of farms in the USA, China, Russia, India, Japan and the EU countries conduct their farming in harmony with nature. The ultimate goals of their activities are ecologically balanced farming, animal husbandry and this agriculture industry technology acts as an alternative to traditional (industrial) farming. Development of organic agriculture involves the search and implementation of new technologies from a science-based position and due to the laws of optimal environmental management. In the article, the authors substantiate the need to enhance introduction of organic farming methods in order to ensure sustainable development and sustainable use of natural resources. Based on the study of foreign agriculture experience, the authors developed a number of key measures for the development of organic agriculture in Russian conditions.

Abstract:

Corn (Zea Mays) is the most cultivated cereal in the world and this is a staple food for human beings that is why in recent years they are looking for alternatives to improve their production. On the other hand, whey is a residual effluent from the dairy industry generally eliminated in sewage, however, due to its high organic load it can be used to produce different biofertilizers. The objective of this study was to evaluate the effect on the production of the corn crop when applying a biofertilizer obtained by anaerobic fermentation of whey and bovine manure. The study was conducted between October 2018 and February 2019, in the experimental area of the Calaspam association, located in Majes, Arequipa-Peru. A complete randomized block experimental design was used in a 2×4 factorial scheme composed by three biofertilizer treatments (6.9 and 12 LBF/water) and a control treatment with three replicates applied with an average flow rate of 1.5 Lha-1. Morphological, post-harvest and economic indicators were determined, as well as the chlorophyll content. Results indicate that biofertilizer treatments improved the indicators studied. The third treatment shows higher values in all the indicators compared to the other treatments, being the values of yield (79,29±7,33 103 kgha-1) and marginal return rate (85,73%) the most outstanding. It is concluded that the biofertilizer obtained from bovine manure and whey has a positive effect on corn production and its application is economically viable.

Abstract:

We conducted a comprehensive review of air emissions resulting from burning wood residues in industrial boilers and potential methods to control these emissions. This report compares average emissions with similar data published by the U.S. Environmental Protection Agency for the burning of fossil fuels coal, oil, and natural gas in industrial boilers. As compared with coal or oil combustion, wood combustion in boilers generally leads to lower emissions of trace metals, hydrochloric acid, sulfur dioxide (SO2), and nitrogen oxides (NOx); higher emissions of carbon monoxide, polyaromatic hydrocarbons, and total volatile organic compounds; and comparable emissions of particulate matter and polychlorinated dibenzo-dioxins and -furans (PCDDs/Fs) (both of which are highly dependent on the efficiency of the ultimate particulate matter control device). Most importantly, wood combustion is carbon dioxide-neutral, a distinct advantage over fossil fuel combustion. Firing wood in stoker units with sulfur-containing fuels, such as coal and oil, leads to a reduction in expected SO2 emissions because of the high carbon and alkali content of most wood ash, and cofiring wood with coal also has some benefits for NOx reduction. This report also discusses the generation and types of combustion ashes resulting from wood burning in mostly combination boilers in the United States and Canada, and provides an overview of ash management practices and the salient characteristics of such ashes relative to their trace metal, organic, and PCDD/F contents.

Abstract:

Repeated food scandals in China have prompted growing consumer consciousness on food safety and health. Organic food, considered to be of higher quality, is being increasingly demanded by Chinese consumers. This study examines preferences for organic labels to provide insight on the sustainable development of the Oolong tea industry. Research was conducted using the choice experiment (CE) method in Fujian and Guangdong Provinces. The results demonstrate that place of origin, organic label, and brand attributes are all significant factors affecting the purchase of Oolong. Also, people demonstrated significantly positive attitudes toward organic labels and preferred Oolong tea from Fujian Province to those from Guangdong Province and Taiwan. Increasing trust can enhance consumer preference and willingness to pay (WTP) for organic labels. Contrary to previous studies, people have a higher WTP for Chinese organic labels than Japanese and American ones. This is probably because respondents are more familiar with domestic Oolong tea and trust more in Chinese organic certification. This provides an opportunity for domestic producers to tailor their organic food labels and better satisfy consumer demands. These findings suggest that the Chinese government should take more responsibility for reducing food-related fraud and thus improve consumer trust regarding organic food.

Abstract:

The treatment of dyeing and printing wastewater from the textile industry by oxidation was studied. The reaction was carried out in a two-litre high pressure reactor. In order to promote the oxidation of organic pollutants present in the wastewater, experiments were conducted using various catalysts including metal salts, metal oxides, and porous alumina supported metals. All catalysts tested were able to enhance the conversion of organic compounds in wastewater, shorten the reaction time, and lower the reaction temperature. The alumina supported catalyst has an advantage over other catalysts in that it can be easily separated from the treated wastewater by filtration and recycled. The conditions in preparing the catalyst supported by porous alumina were experimentally optimised.

Abstract Two experiments were conducted to determine the effects of trace mineral source and level for grow-finish pigs. In Exp. 1, 2,168 pigs (initial BW = 23.0 kg) were used in a 117-d trial. There were 5 treatments based on inorganic (sulfates and oxides) or organic (Alltech Bioplex, Lexington, KY) minerals supplemented at different levels as follows: 1) Industry inorganic (120 mg/kg Zn, 100 mg/kg Fe, 40 mg/kg Mn, 10 mg/kg Cu); 2) 100% NRC inorganic (60 mg/kg Zn, 60 mg/kg Fe, 2.2 mg/kg Mn, 4 mg/kg Cu); 3) 33% NRC organic (20 mg/kg Zn, 20 mg/kg Fe, 0.7 mg/kg Mn, 1.3 mg/kg Cu); 4) 66% NRC organic (40 mg/kg Zn, 40 mg/kg Fe, 1.5 mg/kg Mn, 2.6 mg/kg Cu); and 5) 100% NRC organic (60 mg/kg Zn, 60 mg/kg Fe, 2.2 mg/kg Mn, 4 mg/kg Cu). Selenium level was 0.30 mg/kg for all treatments. Treatment 1 had 14 replicates and the other treatments had 18 replicates. Pigs were weighed approximately every three weeks and carcass data was collected at the end of the trial. Data was analyzed with SAS MIXED procedure. There was no evidence for differences (P > 0.10) for overall ADG, ADFI, G:F, and final BW. Pigs fed 66% NRC organic had the highest (P < 0.05) percentage lean and loin depth. In Exp. 2, 1,188 pigs (initial BW = 25.9 kg) were used in a 120-d trial with two treatments: 1) Industry inorganic and 2) 66% NRC organic, with the same mineral levels as Exp. 1 and 24 replicates per treatment. There was no difference (P > 0.10) in growth performance. Similar to Exp. 1, pigs fed 66% NRC organic had higher (P < 0.05) percentage lean and loin depth. In conclusion, lower levels of organic trace minerals resulted in improved carcass characteristics without compromising growth performance.

AbstractGreen marketing in Kosova evolved as a means for enterprises to adjust to increased market competitiveness. The objective of the study was to identify how consumers’ environmentally friendly behaviour drove the demand for new eco-value market offerings. Concurrently, the study aimed to prove how domestic producers of non-alcoholic beverages used their capabilities to deliver new eco-value market offerings. The research is based on a survey conducted in Kosova. Analysis focused on statistical correlation testing of consumers’ green marketing awareness, behaviour toward the environment, information search, trust in advertising and labels displaying health benefits of beverages and attitudes towards a willingness to pay more for organic non-alcoholic beverages compared with non-organic ones. Significant findings were the positive influence of family and media in shaping consumers’ environmentally friendly behaviour and, in contrast, consumers’ mistrust in the marketing activities of producers as a consequence of misleading advertising.

Abstract:

ABSTRACT The efficacy of 28 individual or blended disinfectants against avian Salmonella enterica serovar Enteritidis and Escherichia coli strains was determined. An in vitro test in the presence and absence of serum as source of organic material was conducted. Povidone-iodine (releasing 1% available iodine), 1% potassium permanganate, 70% ethanol, 2% chlorhexidine digluconate and three commercial formulations based on quaternary ammonium compounds + formaldehyde or cresol derivates were the most effective against all strains tested and reduced bacterial counts by more than 106 times (6-log10) regardless of the presence of organic matter. These commercial compounds as well as ethanol and chlorhexidine among the individual substances tested might be helpful in the adoption of environmental control measures against these two enterobacteria in poultry industry.

One of the tourism products developed and a mainstay of the Bondowoso Regency Government is the organic tourism village in Lombok Kulon. However, the limitation of adoption of integrated information technology is the reality in the management of organic tourism village objects. The purpose of this study is to: a). identify the driving and inhibiting factors faced by the manager of the Lombok Kulon organic tourism village to adopt information technology for the development of an organic tourism village, b). formulate a business process design for the development of e-Tourism organic tourism village in Lombok Kulon in accordance with the conditions of supporting resources. This research was conducted by survey method to members and managers of organic tourism villages. The results showed that in the technological aspects, organizational aspects, and environmental aspects provided a strong impetus for technology adoption. This is evident from the recapitulation of the decision to adopt technology. Nevertheless, the inhibiting factor for the adoption of information technology is the assumption of members and managers that the technology to be applied in developing e-Tourism is a technology that is quite difficult.
