This condition causes the Ciliwung River to be polluted because it becomes a place for liquid and solid waste from both household and industrial activities. To find out how much pollution there is in the Ciliwung River, this research was carried out. The purpose of this study was to determine the status of water quality in the Ciliwung River by analyzing data from water quality monitoring results from 2015 to 2020 from 3 (three) Onlimo Stations representing the upstream, middle, and downstream of the Ciliwung River. The parameters analyzed were temperature, dissolved oxygen (DO), total dissolved solids (TDS), electrical conductivity (DHL), pH, and turbidity. The method used in this analysis is descriptive statistics and the STORET method to determine the status of pollution levels in the Ciliwung River. The results of the analysis in this study showed that of the 6 observed parameters, the values of pH, TDS, and DHL met the quality standards. Meanwhile, DO values, temperature, and turbidity still do not meet the Class 2 river water quality standards according to Government Regulation No. 82 of 2001, especially at Pintu Air Manggarai Station and Istiqlal Mosque Station. Analysis of the water quality status of the Ciliwung River shows that the polluted condition is moderate to severe. \u0000ABSTRAK \u0000Sungai Ciliwung merupakan salah satu dari 13 sungai yang ada di wilayah Jakarta dan mengalir di tengah Kota Jakarta melewati banyak pemukiman padat. Kondisi ini mengakibatkan Sungai Ciliwung tercemar karena menjadi tempat pembuangan limbah cair dan limbah padat dari kegiatan rumah tangga maupun industri. Untuk mengatahui kondisi seberapa besar pencemaran yang terjadi di Sungai Ciliwung, maka dilakukan penelitian ini. Tujuan dari penelitian ini adalah mengetahui kondisi status kualitas air di Sungai Ciliwung dengan menganalisis data hasil pemantauan kualitas air tahun dari 2015 sampai 2020 dari 3 (tiga) Stasiun Onlimo yang mewakili hulu, tengah dan hilir sungai Ciliwung. Parameter yang dianalisis adalah suhu, oksigen terlarut (DO), total padatan terlarut (TDS), daya hantar listik (DHL), pH, dan kekeruhan (Turbidity). Metode yang digunakan dalam analisis ini adalah statistik deskriptik dan metode STORET untuk menentukan status tingkat pencemaran di Sungai Ciliwung. Hasil analisis dalam penelitian ini menunjukkan bahwa dari 6 parameter yang diamati, nilai pH, TDS, dan DHL memenuhi baku mutu. Sedangkan nilai DO, suhu, dan kekeruhan masih tidak memenuhi baku mutu air sungai kelas 2 menurut PP No. 82 tahun 2001, terutama di Stasiun Pintu Air Manggarai dan Stasiun Masjid Istiqlal. Analisis status mutu kualitas air Sungai Ciliwung menunjukkan kondisi tercemar sedang menuju berat. ","PeriodicalId":31853,"journal":{"name":"Jurnal Sains Teknologi Lingkungan","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84571953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to obtain preliminary data to assess the feasibility of using the foam fractionation method for the recovery of protein from tofu whey wastewater. Tofu whey in our study had an initial protein concentration of 3115 mg.L-1. The experiment was performed using a column foam fractionation reactor in a semi-batch mode. Combinations of three air flow rates (10, 30, and 60 L.h-1) and three tofu whey concentrations (10, 50, and 100%) were tested. Our results show that initial protein concentration influenced protein recovery, with a protein concentration of approximately 3000 mg.L-1 required. The highest enrichment ratio of 1.0 ± 0.5, which corresponded to 6 ± 4% protein recovery, was achieved at 10 L.h-1 flow rate and 100% whey concentration. Increasing the flow rate to 30 L.h-1 did not change the enrichment ratio (0.9 ± 0.2), but increased the protein recovery to 71 ± 14%.

One industry that has a high demand for clean water is the can industry. This water is widely used especially for the production process. The existing problem is the limited availability of water sources and the uncertainty of supply continuity as well as the increasing operational costs. One alternative solution to the problem of water demand is to optimize the recycled water from the wastewater treatment plant and maintain the capacity of the processed water from the Reverse Osmosis (RO) unit for process needs in the industry. The wastewater recycling treatment process is divided into two stages, namely the production wastewater treatment plant process with chemical and filtration processes, and the recycled water treatment process with the RO process. The RO process water is used for the can washing process. In maintaining the capacity and quality of RO production water, several efforts have been made including; replacing lamella units, cleaning RO membranes, increasing pH values, reducing conductivity values, replacing membranes and others. So, with the maintenance and optimization of RO unit production capacity, the can washing production process will be maintained and also increased. Currently, the installed RO water production capacity is 200 m3/day. One way that has a dominant influence in maintaining this capacity is to replace the lamella unit, which serves to improve the quality of RO raw water, so as to extend the service life of the RO membrane. \u0000  \u0000ABSTRAK \u0000Meningkatnya kebutuhan industri akan air bersih sejalan dengan tingkat pertumbuhan penduduk saat ini.

POME wastewater can produce Greenhouse Gases (GHG) and high levels of organic materials such as COD, BOD, and total nitrogen, which have impacts on the environment. This study aims to analyse the environmental impacts of POME wastewater treatment using the Life Cycle Assessment (LCA) method based on SNI ISO 14040:2016. The LCA analysis was aided by SimaPro v 9.3.0 software using the IMPACT 2002+ calculation method. The research focuses on measuring the environmental impacts of the POME waste treatment process in a 1 ton CPO production unit, with impact categories including global warming, water eutrophication, and respiratory organics. The research limitation is set to \"gate to gate\" due to the input being limited to the waste treatment process of the production plant. It was found that the environmental impacts generated are as follows: Global warming (8.47E+08 kg CO2eq/day) with contributions from biogenic CH4, N2O, fossil CH4, and fossil CO2 emissions; water eutrophication (33,622.8 kg PO4eq/day) with contributions from COD and total nitrogen emissions; and respiratory organics (253,197.7 kg C2H4eq/day) with contributions from biogenic CH4 emissions. In this case, the sludge pit process has the highest contribution to each impact category, accounting for 37.8%. The high percentage of contribution from the sludge pit to the impact category is known due to the biological process of organic matter decomposition, which generates methane biogas. Therefore, a recommended approach that can be implemented to manage POME waste sustainably is to construct an anaerobic digester to capture the released biogas and utilize it as an energy source for biogas power plants. This action is environmentally, economically, and socially viable.\u0000 \u0000ABSTRAK \u0000Salah satu potensi limbah yang dapat dihasilkan oleh Proses Produksi CPO adalah Palm Oil Mill Effluent (POME).

The wastewater treatment process is based on biological processes with bacteria as the decomposition medium often produces activated sludge. The level of activated sludge in the system (wastewater treatment unit) must be controlled and reducing it by removing it from the system is necessary when it exceeds normal limits. However, directly discharging activated sludge into the environment without prior separation can impact environmental pollution. In this study, activated sludge (simulated with CaCO3) was tried to be separated from water using the plate-frame filter press method. Various variables are the concentration of activated sludge in the form of CaCO3 solid dissolved in water with a concentration of 1–4% w/w, and the type of filter used was cotton cloth and drill cloth. This study aimed to determine the performance of the solid-liquid separation process in the form of a CaCO3 solution using the plate-frame filter press method based on the resulting solids removal efficiency (CaCO3). The results showed that filter performance using cotton cloth produced better performance than drill cloth, with a solute efficiency of 56.00%, obtained at a CaCO3 concentration of 4% w/w.\u0000ABSTRAK\u0000Air limbah sebelum dibuang ke lingkungan harus memenuhi baku mutu sesuai dengan persyaratan yang berlaku. Di dalam proses pengolahan air limbah yang berbasis proses biologis dengan bakteri sebagai media pengurainya, seringkali menghasilkan lumpur aktif (activated sludge). Kadar lumpur aktif yang ada di dalam sistem (unit pengolahan air limbah) harus terkontrol kadarnya, dan ketika melebihi batas normal, maka perlu kurangi dengan cara dikeluarkan dari sistem. Tetapi pembuangan lumpur aktif secara langsung ke lingkungan tanpa pemisahan terlebih dahulu dapat berdampak kepada pencemaran lingkungan. Pada penelitian ini, lumpur aktif (disimulasikan dengan CaCO3) dicoba dipisahkan dari air menggunakan metode plate-frame filter press.  Variabel yang divariasikan adalah konsentrasi lumpur aktif (activated sludge) berupa padatan CaCO3 yang dilarutkan di dalam air dengan konsentrasi sebesar 1–4% drill, dan Jenis filter yang digunakan adalah berupa kain katun dan kain drill. Tujuan penelitian ini adalah untuk mengetahui performa dari proses pemisahan padat-cair berupa larutan CaCO3 menggunakan metode plate-frame filter press berdasarkan efisiensi penghilangan padatan (CaCO3) yang dihasilkan. Hasil penelitian menunjukkan bahwa performa fllter dengan menggunakan kain katun menghasilkan performa yang lebih baik dibandingkan dengan menggunakan kain drill, dengan efisiensi solute mencapai 56,00%, yang diperoleh pada konsentrasi CaCO3 sebesar 4% berat.","PeriodicalId":31853,"journal":{"name":"Jurnal Sains Teknologi Lingkungan","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82438044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The various functions of the lake by the community in the Lake Batur area are now more utilized as a medium for fish cultivation in floating net cages (KJA), food crops, fruits, and various vegetables. Now they are concerned because the increase in KJA has exceeded its carrying capacity, so the waste it produces causes water quality problems, which threatens the sustainability of the KJA cultivation marked by mass fish deaths that occur every year. It is necessary to conduct a study about this phenomenon to determine the aspirations or opinions and understanding of environmental conditions in sustaining farming activities. Aspirations have been obtained by interviewing the Lake Batur farming community. The study results show that the community believes that the current environmental conditions of Lake Batur are still good and can provide decent and profitable results for both KJA fisheries and agricultural businesses.  In principle, the community is aware of the economic dependence of its life on the existence of Lake Batur. The community does not want the balance of Lake Batur to be disturbed and if it is disturbed, the community is willing to cooperate with the government to restore it in any way, including monetary contributions. \u0000ABSTRAK \u0000Danau Batur, danau terbesar di Bali, memiliki bermacam-macam fungsi, antara lain  bahan baku air bersih, obyek wisata, budidaya perikanan, air untuk pertanian, fungsi lingkungan, dan transportasi. Berbagai fungsi danau tersebut oleh masyarakat di kawasan Danau Batur kini lebih dimanfaatkan sebagai media budidaya ikan di keramba jaring apung (KJA), tanaman pangan, buah-buahan, dan aneka sayuran. Saat ini masyarakat kawatir, karena peningkatan KJA telah melampaui daya dukungnya sehingga limbah yang dihasilkannya menyebabkan masalah kualitas air, yang justru mengancam keberlanjutan budidaya dengan KJA tersebut yang ditandai dengan kematian masal ikan yang terjadi setiap tahun. Berkenaan dengan fenomena tersebut maka dirasakan perlu dilakukan kajian untuk mengetahui aspirasi atau pendapat dan pemahaman terhadap kondisi lingkungan dalam menopang kegiatan usaha tani. Aspirasi telah diperoleh dengan cara wawancara kepada masyarakat petani Danau Batur. Hasil kajian menunjukkan bahwa masyarakat berpendapat kondisi lingkungan Danau Batur saat ini masih baik dan dapat memberikan hasil layak dan menguntungkan baik untuk  usaha perikanan KJA maupun usaha pertanian. Pada prinsipnya masyarakat sadar akan ketergantungan ekonomi kehidupannya terhadap keberadaan Danau Batur. Masyarakat tidak ingin keseimbangan Danau Batur terganggu dan jika terganggu, masyarakat bersedia bekerja sama dengan pemerintah untuk memulihkannya dengan cara apapun, termasuk kontribusi uang.","PeriodicalId":31853,"journal":{"name":"Jurnal Sains Teknologi Lingkungan","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83973159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
