Full textAbstract:
The determination of pollution status is an important process of environmental quality monitoring especially in strategic waters for coastal areas, such as in Lampung Bay. An effective and sensitive Water Quality Index (WQI) method is needed, to accurately determine the environmental pollution status. This study aimed to compare the sensitivity of Storage and Retrieval of Water Quality data System (STORET) and Pollution Index (PI) as a WQI method, a case study from Lampung Bay coastal waters, Indonesia. Water quality analysis i.e. Dissolve Oxygen (DO), pH, salinity, nitrite, nitrate, phosphate and ammonia was conducted spatially (three zones of Lampung Bay; river mouth, aquaculture and bay area) and seasonally (April and October 2015). The study found that nitrate and phosphate values were exceeded the limits of water quality standard (Indonesia Ministry of Environment Decree No. 51/2004) for marine organisms. However it may still support the aquaculture activities. The two WQI methods produced different pollution status of Lampung bay. STORET was found to be more sensitive method. Pollution Index method revealed a status of moderately polluted while STORET showed heavily polluted status. Therefore, this study suggest the use of STORET index, compare to Pollution Index, in an assessment of pollution status at watershed area.

<p>Grenjeng River is one of the irrigation water resources which is currently polluted by waste from industrial, livestock and domestic activities. This study aims to assess the quality and index of water pollution based on physical-chemical and biological parameters in the Grenjeng River, Boyolali Regency. Sampling of river water was carried out in dry and rainy seasons which were taken at three observation stations (upstream, middle stream and downstream). Results from laboratory analysis were compared with water quality standards according to Government Regulation No.82/2001, and quality status was based on the Pollution Index method in accordance with the attachment to Minister of Environment Decree No.115/2003. This study shows that BOD of 53-5.7 mg L<sup>-1</sup>, COD of 49-510.5 mg L<sup>-1 </sup>and total coliforms of 540-2,400,000 mLin dry season have exceeded the quality standard water classes, while in rainy season total coliforms 24,000-240,000 mLhave exceeded the standard water for all water classes. The pollution index of the river water in dry season has reached polluted to extremely polluted levels and the index of the river water in rainy season has reached moderately polluted to polluted levels. This condition shows that the practice of dumping waste into river bodies can directly affect river water quality. The irrigation water source for agricultural must comply with irrigation water quality standards so that is suitable as irrigation water for plants. Environmentally friendly approach is needed to prevent worse pollution, which is done by increasing public awareness and business actors in managing liquid waste by making the integrated wastewater treatment system.</p>

Full textAbstract:
Land use is one of the macro parameters that affects water quality in a watershed. The Cimanuk watershed which is dominated by agricultural land use and settlements has encountered a decline in water quality. There are eight parameters including pH, TDS, TSS, Nitrate, Phosphate, Sulphate, BOD, and COD analyzed to evaluate water quality utilizing the Pollution Index (IP) method. This research has provided a clear understanding of the status of water quality in the Cimanuk watershed based on six monitoring points carried out at the start of the 2018 rainy season. Overall, the IP values obtained ranged from 2.05 to 5.96 with the lightly polluted category at points A, B, C, D, and E, while for point F it was in the moderately polluted category. The key parameters that have the most influence on water quality pollution are Nitrate, Phosphate, Sulphate from fertilization activities in agricultural land, while runoff from settlements contribute to increasing parameters of BOD and COD. These results can be beneficial for sustainable management of water and land resources in the Cimanuk watershed.

This study examined the water quality of Saguling Reservoir as potential raw water for Bandung metropolitan area. Determination of water quality in this study consisted of trophic status determination based on total phosphorus, total nitrogen (ammonia and nitrate), and water clarity. Data were obtained 4 times a year for 16 years (1999-2013). We determined the overall water quality status by comparing data with criteria specified in Ministerial Regulation (Permen) of the Environment Number 28 of 2009 on the Water Pollution Load Capacity of Lakes or Reservoirs. Data from 11 stations were analyzed, which indicated a hypertrophic state with very high pollution. Nanjung Post (upstream of the reservoir) had the highest levels of total P, total N, and chlorophyll a compared with the Muara Ciminyak Post and Muara Intake Post (the middle and downstream regions of the reservoir). Seasonal changes had no effect on the trophic status, regardless of dry, normal, or wet conditions.

Smoke-haze episodes caused by vegetation and peat fires affect parts of Indonesia every year with significant impacts on human health and climate. The forest fires 1997/1998 were by far the largest in Indonesian history, burning between 5 and 8 million hectares before they were stopped by the monsoon rains in December 1997. Fires sprang up again in 1998 on Kalimantan when monsoon rain paused. Peat forests and peatlands are in particular severely affected. In the 1997/1998 haze event, 2.1–2.5 million hectare of peat swamp forest burnt in Indonesia. The remaining ash contains high concentrations of sulphur and sulphuric compounds which eventually leach into the groundwater, thus polluting groundwater and drinking water. The thicker the peat layer is and the higher the number of fires in the respective area the more sulphuric compounds will leach into the groundwater. Risk areas for the sulphur loads of the ash are identified.

The growth of industrial world is an undeniable problem in the environment where industrial behavior often ignores impacts on the environment, such as water, soil, air pollution and social inequality in the environment. The purpose of this study is intended to determine the role of green accounting in reducing environmental pollution and to examine the extent to which the application of green accounting in Indonesia in supporting sustainability. This study uses an interpretive approach which focus on the subjective nature of social world and tries to understand it. Green accounting has difficulty measuring the value of costs and benefits of externalities arising from industrial processes. It is not easy to measure the loss to people around and the ecological environment caused by air pollution, liquid waste, ammonia tube leakage, nuclear tube leakage or other externalities. Unfortunately, in its application, often some companies do not report bad news they are facing, so reporting on environmental costs is not effective.

Full textAbstract:
Attention towards microplastic (MP) pollution in various environments is increasing, but relatively little attention has been given to the freshwater-riverine environment. As the biggest city in the eastern Indonesia region, Makassar can be a potential source of MP pollution to its riverine area. This study aimed to determine the spatial trends, seasonal variation, and characteristics of MPs in the water and sediment of Tallo River, as the main river in Makassar. Water samples were collected using a neuston net and sediment samples were collected using a sediment corer. The samples collected contained MPs with an abundance ranging from 0.74 ± 0.46 to 3.41 ± 0.13 item/m3 and 16.67 ± 20.82 to 150 ± 36.06 item/kg for water and sediment samples, respectively. The microplastic abundance in the Tallo River was higher in the dry season and tended to increase towards the lower river segment. Fragments (47.80–86.03%) and lines (12.50–47.80%) were the predominant shapes, while blue (19.49–46.15%) and transparent (14.29–38.14%) were the most dominant color. Polyethylene and polypropylene were the common MP polymers found in the Tallo river. Actions to prevent MP pollution in the Makassar riverine area are needed before MP pollution becomes more severe in the future.

The problem of environmental pollution especially urban water pollution becomes major issue in Indonesia. The cause of water pollution is not only from industrial factory waste disposal but also other causes which become pollution factor. One cause of water pollution is the existence of agricultural activities with the use of the amount of pesticides that exceed the threshold. As regulated in Government Regulation No. 82/2001 on Water Quality Management and Water Pollution Control, it is necessary to manage water quality and control water pollution wisely by taking into account the interests of current and future generations as well as the ecological balance. To overcome the problem of water pollution due to agricultural activities, it is necessary to conduct research on phytoremediation technique by utilizing eceng gondok plant. It is excepted that using this phytoremediation technique can reduce the problem of water pollution due to the use of pesticides on agricultural activities.

In the past, village people of Karangwangi, Cianjur District, West Java Province did not face any problem of water supply, including supply from the Cikawung River. Of late, however, they are experiencing problems with water sources, particularly water supply from the Cikawung River. Since pesticides have been intensively used in the local agroecosystems, such as irrigated rice fields and monoculture vegetable gardens, the Cikawung river water is polluted. In addition, the consequences of increase in conversion of forests and traditional mixed-gardens into agricultural and settlement areas have dramatically affected hydrological balances. On this background, this research was carried out to elucidate the local knowledge of the Karangwangi people on the status of pollution of water of the Cikwaung river. This research used a mix of qualitative and quantitative methods with descriptive qualitative analysis. Qualitative data collection technique used was deep interviews with informants chosen purposely with snowball sampling. Quantitative data collection technique was interview with respondents using questionnaires and measurement of physical, chemical and biology parameters of Cikawung River water. Results of this research confirm that village people of Karangwangi have considerable local knowledge on water categorization, pollution and pollution indicators of Cikawung River

Full textAbstract:
Microplastic is generally defined as synthetic polymers which size less than 5 mm. Based on the latest research, microplastics pollutions have many impacts on the environment and human. Jatiluhur, as one of the biggest freshwater reservoir in Indonesia, has potential to be polluted by microplastics because the water source of this reservoir streamed from Citarum watershed. Citarum River is one of the most polluted river in Indonesia. To find the occurrence of microplastics and to facilitate future policies in order to overcome microplastic pollution which occurs in Jatiluhur Reservoir, a study of microplastic abundance is conducted. Primary data is obtained by using the volume reduced sampling method. Manta trawl is pulled beside a boat for 5 -15 minutes for each sample and flow meter installed onto the mouth of manta trawl to determine the towing distance in surface water. Microplastic abundance in surface water presented in the form of microplastics amounts per unit surface area. Furthermore, microplastic characteristics analyzed with visual analysis, particle density analysis, and polymer analysis using FTIR. Based on seven sampling locations, microplastics have found in Jatiluhur Reservoir ranging from 0.71×104 – 4.59×105 particles/km2. The most type of microplastic found is fragmented polyethylene.

The water quality of Lake Tondano is affected by various anthropogenic activities on the water body and catchment area. The purposes of this research were (i) to identify a pollution load based on the study of bioindicators and physicochemical parameters and (ii) to identify the trophic level of the Lake Tondano. The research data were collected by direct water sampling and analyses of a secondary data. The plankton identification was conducted in a laboratory. The data were analyzed to determine biodiversity index (ID) using the Shannon Weiner formula. A comparison between physicochemical parameters and the standard in the government regulation number 82, the year of 2001 and the value of diversity index were used to determine the pollution level. The trophic level was calculated with the Carlson Formula. The results showed that the diversity index (H') in Lake Tondano was 1.904 (phytoplankton), 1.712 (zooplankton) and 2.086 (benthos) which indicated a low to mid-level pollution. Based on the government regulation, the Eris station had inappropriate water quality for the present utilization (Class II). The trophic state was categorized as eutrophic towards hypertrophic condition indicated by domination of the phytoplankton and large covers of the water hyacinth.

The problem of water pollution is complex. There are many factors that influence the successfull of efforts for water pollution control. The construction and operation of septage treatment facility (IPLT) is an efforts for controlling pollution from domestic activities. The successfull of IPLT management cannot be assessed from physical aspect of the building only. Other aspects such as quality of effluent, sludge supply, idle capacity, the rate of surface loading and volumetric loading, human resources, organization, standard operating procedures (SOP), the tariff and others should be consider for decision making to manage IPLT better. The purpose of this study is to describe the application of factor analysis method to solve a complex problem of IPLT through identifying the main causes and formulate solutions. Factor analysis is one of decision with multicriteria. The primary data research in 2014 used as reference for analyzing. The conclusion of this study is the factor analysis is able to classify 12 indicators into 3 factors without reducing the meaning of the constituent indicator, thus simplifying the decision making process. Significant factors that affecting the successfull of IPLT performance in controlling water pollution are : continuity of sludge supply, clarity of roles and responsibilities, availability, novelty, accesibility and simplicity of SOP.

Microplastics are harmful to the ecosystem and need to solve immediately. Detection of microplastic contamination is the first step to reduce plastics pollution. Estuarine in Puger has a high potential for microplastic pollution related to the multifunction of waters as ports, tourism, fish market, fish processing, and human settlements. However, there are no studies related to microplastic contamination in the area. The objectives of this research were to determine microplastic contamination in the estuarine located in Puger District, Jember Regency, Indonesia. The research results were the first evidence to inform the society and local government about the actual condition of plastic pollution, especially in the aquatic ecosystem. The sampling sites were determined by purposive sampling. Fifty liters of water from each station (with three repetitions) were taken using a 24V water pump and then filtered using stainless steel filter (mesh 5 mm and 0.2 mm). The filtered samples were placed in a sterile bottle sample, stored at 4 ± 20C. Microplastics were counted and categorized according to size, color, and type under a microscope stereo. Microplastic abundance was calculated based on the number of microplastic particles identified per liter of sample water (particle/liter). The result showed that the study area was contaminated by microplastics throughout site sampling, with abundances varying from 0.03 particles/liter to 0.19 particles/liter. The highest microplastic abundance found near the fishery market. The microplastics also vary in size, color, and type. According to characterization, the sources of microplastic contamination come from human-based activities.

Full textAbstract:
Shrimp farming has contributed a large share in Indonesia’s aquaculture portfolio for at least a decade, and a national plan to increase shrimp production by 250% has been recently laid out. However, boosting shrimp productions could lead to unintended consequences in environmental and socio-economic negative impacts. The rapid development of vannamei farming in Java has increased coastline land clearings and demands of fertilizers, feeds, and chemicals to sustain the farming activities. Such pressures will eventually lead to a reduced environmental capacity and the farming efficiency itself. This study aimed to study the environmental impacts and business performance of intensive shrimp farming in Indonesia. The study was conducted in Aquaculture Business Center (ABC) in Karawang for four months, from July to October 2020. In-situ and ex-situ measurements of water quality parameters were done at six sampling stations directly post-harvest water discharge. The measured parameters consisted of temperature, pH, dissolved oxygen, ammonia (NH3), nitrite (NO2), nitrate (NO3), phosphate (PO4), alkalinity, and salinity. Pollution Index (PI) was used as the primary method to determine the environmental impacts of the shrimp farming. The R/C Ratio was used to analyze the business performance of the company. The results showed that the water quality index in the ABC area was categorized as lightly polluted in station 1 (PIj 4.52) and station 5 (PIj 4.37), moderately polluted in station 2 (PIj 6.24), station 3 (PIj 6.72), and station 4 (PIj 6.13) and heavily polluted in station 6 (PIj 111.06). The determined R/C ratio was 1.10, meaning that the shrimp farming is classified as economically profitable. Although the shrimp farming’s economic performance value is very good, the water conditions affected by waste from the shrimp pond culture will reduce the R/C ratio in the future if not properly managed.

The nitrate concentrations in shallow groundwater of the Yogyakarta City and its surroundings has increased to about twenty times in the period 1985-2018. The objective of this study was to analyse the distribution of nitrate concentrations in water well around the Code River, Yogyakarta. Flownets mapping was performed to find out the distribution and direction of potential groundwater pollution. Nitrate concentration was analysed by taking 18 groundwater samples scattered in the upstream, midstream and downstream areas of the Code River. The results of this study indicate that nitrate concentrations in the water well of upstream and downstream areas could still be used as a source of drinking water and recreation-irrigation-livestock. Meanwhile, the nitrate concentration in water well of the midstream area of the Code River, Yogyakarta City, mostly (80% of the sample) did not meet all classes of water quality standards. Human activities in the densely populated settlements were the main factors that influence nitrate pollution. Furthermore, groundwater flow in the study area leads from north to south and towards the Code River. This condition indicates that the nitrate concentrations in the groundwater can be a source of a pollutant for the Code River.

The development of anthropogenic and tourism activities causes the ecological impact on water quality. The profile of water quality and sediment are the representation of environmental condition of ecosystems, then they could be indicators of pollution, fertility, suitability, and environmental carrying capacity on marine life. This study aimed to characterize the environmental indicator based on the quality profile of Menjangan Besar waters, Karimunjawa, Central Java. Data collection using a purposive sampling method based on water and sediment characteristics in Menjangan Besar waters. The research location is divided into three stations, namely: station A: the waters of fish cage activity; station B: floating guesthouse activity; and station C: seaweed marine culture. Variable on water quality profile consists of N-NO3 (mg/L) and PO4-P (mg/L), chlorophyll-α (mg/m3), and bacterial (CFU/mL), and other water quality support, while the variables on sediment quality profile consist of Phosphorus (mg/g) and PO4-P (mg/g), organic (%), C-organic (%) and bacterial (CFU/g), and sediment grain size. The calculation data analysis method of water and sediment total bacteria profile used Total Plate Count (TPC) by following SNI 7545.1 (2009), while analysis for nitrification bacteria (Nitrosomonas and Nitrobacter) using Most Probable Number (MPN). Data analysis of sediment grains size used two methods, i.e. (i) dry mechanic method by using sieve shaker, and (ii) wet mechanic method by using a pipette. Data analysis of nitrate and phosphate using Brucine Sulfanilik method. Mapping of the spatial distribution of measurement data for water nutrient contents (NO3-N and PO4-P), bacteria, and Chlorophyll-α in the waters using ArcGIS software application tool. The results showed that nitrification bacteria content in the water column is lower than in the sediments layer. Total bacteria content in both the water column and sediment layer varies between stations. Total bacteria in station A is higher than the other stations. The water nutrient content (Nitrate and Phosphate) is still above the quality standard for Marine Biota (Kepmen LH No. 51/2004). The condition of the fertility of Menjangan Besar waters is oligotrophic tend to mesotrophic, in the sense that the waters quality is low to medium conditions, and not yet dangerous for marine biota.

Heavy metals have been reported to accumulate in sediment of Citarum River. The measurement of total heavy metals may not be able to provide information about the exact dimension of pollution, thus the determination of different fractions assumed great importance. This study was performed to determine chemical fractions of heavy metals (Cu, Ni, Cr, Pb and Cd) in sediment collected at 8 locations from Citarum River. The sequential extraction procedure was used to extract heavy metals in water-soluble, acid-soluble, MnO occluded, organically bound, FeO occluded and residual fraction in sediment. Bioavailability and potential ecological risk level of heavy metals were evaluated based on bioavailability factor (BF) and risk assessment code (RAC) method. The results showed that Cu, Ni, Cr were mostly in residual form, indicate those from geological sources. Cu had low bioavailability and no risk in all sediment samples of Citarum River. Ni and Cr each was found to have risk at 2 locations. Pb and Cd were found dominantly in non-residual fraction, suggest those from anthropogenic sources. BF and RAC analysis of Pb and Cd suggest that there is a potential risk to the aquatic environment.

Full textAbstract:
Wells as a source of water that is commonly used by people in Indonesia are very dependent on the conditions of the surrounding environment. The presence of environmental pollution by waste will be very dangerous, especially if the waste contains heavy metals such as Cr(VI). The highly soluble nature of Cr(VI) allows the process of infiltration from the river into the well water. This study aims to analyze the content of Cr(VI) in the well water of residents around the Citarum River. Samples were taken from two areas that have the criteria for the level of pollution and the environment which is dense with industrial activity, with a total of ten wells spread over the area. The concentration measurement was carried out using an atomic absorption spectrophotometer at a wavelength of 357.9 nm. The results showed that the levels of Cr(VI) ion at Location 1 were in the range of 0.014 – 0.022 ppm so that it could still be used for daily activities because it was below the threshold value. At Location 2, there are six wells whose water is still suitable for use because the value of the Cr(VI) ion content is still below the threshold value. Meanwhile, the water in the other four wells contains Cr(VI) ion level that exceeds the threshold value, so it can be said that it is not suitable for daily use.

Full textAbstract:
Saguling Reservoir is one of the Citarum Cascade reservoirs located in the upstream area at an altitude that is 643 meters above sea level in West Java, Indonesia. The Saguling Reservoir functions as a hydroelectric power plant (PLTA), a water supply provider for irrigation, and flood control. This research aims to determine the capacity of the water pollution loading accordance with reservoir operating patterns that consist of dry, normal and wet years, based on Government Regulation No. 37 of 2010 concerning Dams. The pollution load in the reservoir is limited by the Total-P concentration that is caused by the fishery’s activities in the water body, especially concerning the Floating Net Cage (KJA) systems. The analysis of water quality status and optimization of reservoir management was carried out by Discrete Markov discharge classification which conducted in 1998-2018. A trophic status analysis of the Saguling Reservoir showed that the waters have entered the hypereutrophic criteria. This study also reveals that the Saguling Reservoir has the lowest pollution load capacity in the dry year, with values of 5,212.7 ton P per year, followed by 6,003.7 ton P per year during normal years, and 6,423 ton P per year during wet years. These results indicate that the value of the carrying capacity of the Saguling Reservoir will be smaller during the dry years. Therefore, based on this research, the ideal number of KJA that can be accommodate by Saguling Reservoir during the dry, normal and wet years, respectively, 22,141 units, 25,500 units, and 27,284 units. Meanwhile, the actual current number of KJA is 35,482 units, which has exceeded the reservoir’s carrying capacity, especially in the dry years.

Full textAbstract:
A list of marine isopods recorded from Indonesia has been compiled from the literature published between 1857 and 2012 as well as from Museum Zoologicum Bogoriense’s collections and current expeditions. To date, 225 marine species from 97 genera and 19 families have been recorded from Indonesia with two parasitic families Cymothoidae and Bopyridae showing the largest number of species: 63 and 41, respectively. As for the sampling sites, waters surrounding Java, Maluku and Sulawesi have been investigated most intensively with 55, 51, and 40records, respectively. The most comprehensive publication of marine isopods in Indonesia has been that by Nierstrasz (1931). In terms of role as bioindicators, Sphaeroma and Dynamenella have been discovered to survive in polluted waters in Jakarta Bay, suggesting their potential use as bioindicators of water pollution. Future research on basic taxonomy of isopods in Indonesia as well as their ecological functions are recommended.

There are still many people in Jakarta who throw their garbage into the river, resulting Jakarta city never being absent from the problems of river water pollution and flooding. Pesanggrahan River and Grogol River are some of the big river surrounded by high popullation area. All waste originating from the Pesanggrahan River and the Grogol River is dumped into the Bantar Gebang Landfill. This study aimed to reduce waste entering landfills are by making use of waste that still has economic value.The method used in decision making from various alternatives of the river waste utilization are utility theory and compromise programming. It takes planning to find out the composition and generation of solid waste from those rivers and to determine the potential use of river waste and the action to minimize and handle the river waste. Utilization of river waste that can be applied based on the composition of most waste is open windrow composting and plastic shredding. It is important to concern about river waste since Indonesia has various polluted river, especially by solid waste. By implementing a good river waste utilization, the waste that enters the landfill will be reduced and in line with reduced pollution to the aquatic environment.

Full textAbstract:
Saguling reservoir in West Java Province is becoming increasingly polluted by heavy metals. The purpose of this study was to determine the level of four heavy metals such as Cd, Cr, Cu, and Pb concentration at Saguling Reservoir at ’2 sampling location. Water samples were collected during rainy and summer 2008-2017 to determine the spatial distribution seasonal and temporal variation of different heavy metal contents. Mean metals concentrations in summer seasons were Cd, Cr, Cu, and Pb higher than rainy season. Mean concentration of Cd, Cu, Cr, and Pb in water samples were accordance water quality standard in both season. Heavy metal pollution that occurs in the Saguling reservoir must be monitored because this reservoir is planned to be a source of raw water for Bandung City.
