Laju Produksi dan Karakterisasi Polutan Organik Lindi dari TPA Kaliwlingi, Kabupaten Brebes Purwanta, Wahyu; Susanto, Joko Prayitno
Jurnal Teknologi Lingkungan Vol. 18 No. 2 (2017)
Publisher : Center for Environmental Technology - Agency for Assessment and Application of Technology

Salah satu hasil proses biodegradasi sampah di TPA adalah lindi yang merupakan polutan organik yang berbahaya bagi lingkungan karena berpotensi mencemari tanah dan air tanah. Penelitian ini bertujuan untuk mengetahui kuantitas dan kualitas lindi dari sampah di TPA Kaliwlingi Brebes melalui uji lisimeter. Kuantitas lindi penting untuk memperkirakan spesifikasi disain unit pengolahan termasuk metode pengolahannya. Sedangkan karakteristik lindi penting untuk menentukan efisiensi pengolahan atau target kadar polutan yang diinginkan agar sesuai standard baku mutu. Dari pengamatan diperoleh kuantitas lindi per massa sampah rata-rata mencapai 1.060 liter/kg, sedangkan nilai pH lindi rata-rata 7,6 atau cenderung alkaline. Dari data pengamatan, semakin tinggi kadar air akan semakin besar kuantitas lindi yang dihasilkan. Karakterisasi lindi terhadap parameter BOD5, COD, NH3-N dan TKN menghasilkan nilai yang bervariasi. Nilai rata-rata serta rentang minimal-maksimal yang didapat; BOD5 90,7 mg/l (65 mg/l-130 mg/l), COD 9.679,7 mg/l (6.300 mg/l-12.200 mg/l), NH3-N 134,4 mg/l (80 mg/l-190 mg/l) dan TKN 672,5 mg/l (540 mg/l-890 mg/l). Rasio BOD5/COD sebesar 0,01 menunjukkan tingkat low biodegradability dalam materi organiknya, hal ini disebabkan waktu pengamatan yang relatif singkat dan proses degradasi biologis masih berlangsung.Nilai rasio BOD5/COD yang diperoleh belum menunjukkan nilai yang representatif untuk sampah di TPA Kaliwlingi. Hasil dari karakterisasi lindi untuk beberapa parameterÃ‚Â menunjukkan bahwa biomassa atau sampah yang diteliti tergolong usia muda dan masih dalam proses dekomposisi.Kata kunci : karakterisasi, produksi, organik, lindi, TPA sampah

Waste to energy now become one of the technology solution that is in many developed Ã‚Â countries, in an effort to reduce greenhouse gas emissions from waste. Urban organicÃ‚Â waste is a potential source of greenhouse gases. Methane gas is an energy sourceÃ‚Â that can be used as fuel. It is difficult to find land for Landfill alocation in the major citiesÃ‚Â and often becomes a difficult social problem. Structured Landfill Cell is used to treat theÃ‚Â waste at the landfill, with the aim to use land more scalable, easier waste managementÃ‚Â and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia inÃ‚Â landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cellsÃ‚Â have been filled with garbage. Each cell contains 12,000 m3 soliswaste. ObservationsÃ‚Â carried out on gas productivity of two cells that have been filled, with a dry treatment onÃ‚Â cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. TheÃ‚Â instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, withÃ‚Â the content of CH4 around 40 to 50% in the first month and gradually decreased to reachÃ‚Â 18 to 25% in the fourth month. Carbondioxyde going up and down following condition ofÃ‚Â CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2Ã‚Â and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increaseÃ‚Â with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24Ã‚Â ppm, allegedly associated with the low protein content in the trash. Sewage treatmentÃ‚Â system is proven to increase CH4 gas, yet still needed modifications of structure andÃ‚Â the gas collector pipe system so that productivity can be improved.Key Words : Solidwaste, Metana, Cell System

Integrated watershed management, which aims at restoration of a soundhydrologic regime in the watershed considering water resources utilization,appropriate landuse, water quality control and environmental conservation, is becoming crucially important in Indonesia. Because, the land degradation of watershed in Indonesia more increases every time. There is a growing concern that many parts of the Indonesia watershed will continue to face problems of watershed degradation. The basic problem in most watershed area, especially in Java, is too many people being concentrated on too small land base. Besides that, the causes of watershed degradation are complex and interrelated, such as too much emphasis being placed on economic growth in the management of natural resources, and the continuing presence of poverty, population growth, infrastructural and industrial development. Thus, the exisiting environmental problems and their overall impacts are not only biophysical in nature, but also social.The integrated watershed approach stresses the interaction of all activities that take place throughout the watershed. The strategy of watershed management approach uses new paradigm with people of participation and using community development in operational, practices and bottom up approach.

Pollution in the rivers is generally caused by domestic and industrial waste.Some treatments to solve it can be done individually or collectively. Theeffort can be physical, chemical, or biological treatments chosen by itsform, character, kind, quality, quantity. PT Van Melle Indonesia is a candycompany which produces a high biological waste with COD concentration10000-30000 mg/litre. This paper reports activated sludge reactorperformance to decrease the waste’s organic content. The reactor is abiological waste water treatment, as a sequence of earlier anaerob processwhich still has a high COD (700-4000 mg/litre). A continued reactoroperation done with retention time variation 24 hours, 18 hours, 12 hours,and 6 hours show reduced COD varied 80-90%. The highest efficiencywas 97.59% from the 24 hours retention time, and the lowest efficiencywas 89.5% from the 6 hours retention time.

ABSTRACTThe concentration of dissolved oxygen (DO) be the most attention parameter because can reflect the water quality and the health of aquatic ecosystems. Along the main flow of Citarum river conditions are already heavily polluted due to waste input both household and urban waste, industrial waste, agricultural waste and livestock also, this conditions causes disruption for organism that are inside, one of them is fish. The purpose of this study was to determine changes in water quality due to pollution through the distribution pattern of the DO concentration by performing simulations using models Streeter & Phelps and their effects on fish life in the Citarum River. The results showed the high value of BOD in Citarum River led to a DO decrease, which indicates that this river has been under pressure utilization that exceeds the carrying capacity. This condition affects the presence of fish in Citarum river,where there has been a reduction the types of fish. Only fish that are resistant to low DO conditions that can survive in Citarum river.Keywords: dissolved oxygen, Streeter Phelps model, Citarum RiverABSTRAKKonsentrasi oksigen terlarut (DO) menjadi parameter yang paling banyak mendapat perhatian karena mencerminkan kualitas air dan kesehatan suatu ekosistem perairan. Sepanjang aliran sungai utama Citarum kondisi perairannya sudah tercemar berat diakibatkan masukan limbah, baik itu limbah rumah tangga dan perkotaan, limbah industri, juga limbah pertanian dan peternakan, kondisi ini menyebabkan gangguan bagi organisme yang ada di dalamnya salah satunya adalah ikan. Tujuan penelitian ini adalah mengetahui perubahan kualitas perairan akibat pencemaran melalui pola sebaran konsentrasi DO dengan melakukan simulasi menggunakan model Streeter & PhelpsÃ‚Â dan pengaruhnya terhadap kehidupan ikan di Sungai Citarum. Hasil penelitian menunjukkan tingginya nilai BOD di Sungai Citarum menyebabkan penurunan DO, yang mengindikasikan bahwa sungai ini telah mengalami tekanan pemanfaatan yang melebihi daya dukungnya. Kondisi ini berpengaruh pada keberadaan ikan di Sungai Citarum, dimana telah terjadi pengurangan jenis-jenis ikan. Hanya ikan-ikan yang tahan terhadap kondisi DO rendah yang bisa bertahan hidup di Sungai Citarum.Kata kunci: oksigen terlarut, model Streeter Phelps, Sungai Citarum.

Mercury (Hg) which is contained in aquatic ecosystem can enter and be accumulatedÃ‚Â to organismÃ¢â‚¬â„¢s body, like on petek fish (Leiognathus equulus). The research aimed toÃ‚Â see mercury concentration in aquatic ecosystem, to see mercury concentration in organÃ‚Â of petek fish by AAS (Atomic Absorption Spectrophotometer) and its histopathology response in organs of petek fish. The research was done at Ancol, Jakarta Bay onÃ‚Â October-December 2004. There are 16 samples of water and fish from 3 stations.The analysis result of water quality is compared by standard quality of sea water forÃ‚Â sea organism life (Kepmen LH No. 51, 2004), mercu ry concentration in fish organ isÃ‚Â compared by maximum mercury concentration in fish body by classification of PalarÃ‚Â (2004). Ancol water quality is still on normal condition. Mercury concentration in waterÃ‚Â and petek fish organs had low concentration. Gill and lever contaminated by mercuryis only in station 1 fish, but it is still on normal concentration. Histopathology of petekÃ‚Â fish gill is not abnormal, while the lever is necrosis. Water and petek fish is not a goodÃ‚Â indicator to detect mercury in aquatic ecosystem.Keywords: mercury, petek fish, water, lever, gill, histopathology, accumulation,indicator

Soap is defined as compound of fats, fatty acids and caustics soda. Thesecompounds work to reduce surface tension and increase its cleansing ability. The term “detergent” usually refer to synthetics compounds, but has broader ability, not only reducing surface tension and increasing its cleansing ability but also has softening and emulsifying ability.Unfortunately, detergent in certain concentration can harm to aquatic organism such as plankton, mussel, mollusk and fish. In bioassays test, high detergent concentrations induced mortality in gill cells and reduced filtration rate of the mussel. In some report cited said that concentrations above 0.2 mg/L of anionic detergent already elicited detrimental, and sub-lethal effects in all test organisms.Therefore, in upper Citarum Catchments Area which has detergent concentration significantly above 0.2 mg/L could harm to sessile invertebrate organisms. And in the long period it may influence the diver and abundance of aquatic organisms.
