Evaluation of chloride (Cl-) content and electric conductivity (EC) of ground water in aquifer system is one method to identify salt water movement in aquifer system, which occurred as a result of changes in hydraulic equilibrium which cause by temporary variation of natural recharges and pumping of ground water at many layered aquifers.Salt water movement in Jakarta aquifer system is evaluated based on mapping of chloride content at 500 mg/L and EC at 1500 m mhos/cm in many bored well during period of 1990 – 2000. In the beginning chloride content and EC is in value only and with the addition of attribute data, namely coordinate, it could be used as input data. By using software namely SURF, the above input data is simulate to have a contour map of chloride and EC. Overlapping of the contour map to Jakarta base map will result in thematic map of chloride and EC distribution which represent salt water movement at Jakarta aquifer system.

Water pollution in the big cities in Indonesia, especially in DKI Jakarta has shown serious problems. One of the potential sources of water pollution is domestic wastewater that is wastewater from kitchens, laundry, bathing and toilets. These problems have become more serious since the spreads of sewerage systems are still low, so that domestic, institutional and commercial wastewater causes severe water pollution in many rivers or shallow ground water. Based on the fact that the progress of development of sewerage system is still low, it is important to develop low cost technology for individual house hold or semi communal wastewater treatment such as using anaerobic and aerobic submerged biofilter. This paper describes the pilot plan study of individual household wastewater treatment using anaerobic and aerobic submerged biofilter using plastic fiber media. The raw wastewater in this experiment was from household wastewater. Results of experiment shows that under operating condition 12-24 hours hydraulic retention time, the treated water was physically very clear, and according on chemical analysis the removal efficiency of BOD is 73.24 – 94.92 %, COD 65.80 – 90.76 %, total suspended solids (TSS) 95.60 – 97.69 %, and detergent (MBAS) 56.80 – 88.51 %, respectively. Compared to attempt by using charcoal media, the quality of treated water did not show difference significantly. Kata Kunci : Limbah domestik non toilet, biofilter anaerob-aerob, media serat palstik.

Anaerobic treatment of wastewater with high organic and salt content but low pH (TOC, 14 g/l; salt, 150 g/l; pH,2.7) generated during an “ume boshi” manufacturing process was investigated. Five-fold-diluted “ume boshi” effluent was treated by a draw-and-fill method at a volumetric TOC (total organic carbon) loading rate of 3.0 g/l/d with a TOC removal efficiency of 75%. Five-fold-diluted “ome boshi” effluent was also treated in an anaerobic fluidized-bed reactor (AFBR) at a maximum volumetric TOC loading rate of 3.0 g/l/d, which gave almost the same results as the draw-and-fill method. However, ten-fold-diluted “ome boshi” effluent could be treated in the AFBR at a maximum volumetric TOC loading rate of 11 g/l/d with a TOC removal efficiency of 85%. The methane content in the evolved gas was high, being 70%. The red pigment in the “ome boshi” effluent was completely decolorized by the anaerobic treatment.

A rotating biological contactor (or RBC) is a type of fixed media filter which removes both organic matter and ammonia from water. It can be added to a packaged plant for more efficient ammonia removal, replacing the aerator in both location and function.The RBC consists of a series of rotating discs. These discs are coated with a biological slime like the slime on rocks in a healthy stream. This slime is rotated through the air and and then through the wastewater so that it picks up oxygen in the air and breaks down B.O.D. in the wastewater. Since the discs rotate through the air, there is no need to pump air into the wastewater. And since the slime stays on the discs, there is no need to recycle sludge. The present study describes basic consideration of rotating biological contactor (RBC) system for wastewater treatment. The design of an RBC system must include the following consideration sach as organics and surface loading criteria, staging of RBC units, peripheral velocity, temperature, effluent characteritics and secondary clarifier. The RBC system have some advantages : smaller basin, less upset, high loading rate, nitrification/de-nitrification, high tolerance, low OM Cost, durable constructions, odorless, no noise, and stable sludge characteristics.

Nowadays raw water resources for drinking water are less and less available, especially in Jakarta. For example, the condition of most rivers in Jakarta is extremely polluted by wastewaters, such as domestic and industrial wastewater. Some of industrial wastewater straightly discharged into the rivers are classified as toxic and hazardous wastewater. Therefore all rivers in Jakarta are not feasible to be used as the raw water for clean water treatment processes. Even ground water is not already safe to be used as the raw water for drinking water, because it has commonly been contaminated by seepage of septic tanks and polluted surface waters. Because of that, many people living in Jakarta tried to find other alternatives. Commercially sold mineral water is one good option for supplying drinking water need, but the prices are relatively expensive for most of people.There were more than 1,000 refill drinking water depots growing in the last ten years. They are one of the best answers to many people, but the quality of drinking water is still debatable. In other word, there is not a standard regulation for the water treatment processes, so the depots cannot guarantee that the produced water already fulfill the quality standard of drinking water. In order to give a good service for community living in Jakarta, it is very important to evaluate all aspects of technology, management and services.

TINJAUAN TEKNOLOGI PENGOLAHAN LEACHATE DI TEMPAT PEMBUANGAN AKHIR (TPA) SAMPAH PERKOTAAN
Authors: Purwanta Wahyu 
Published: June 2020

Leachate is defined as a liquid, which flows through waste and extracts suspended material or their suspension. In most landfill, leachate is consist of liquids that go into the landfill, which originated from outside the landfill, such as surface drainage, rain water, ground water, water from spring water and other liquids which produced from waste decomposition. The existence of pollutant material or minerals in water body that is originated from leachate will propose the growth of microorganisms, which are harmful for human health and reduce the aesthetic. Leachate handling could be done with several methods, such as: utilization of hydrolic characteristics by ground water adjustment, thus the leachate flows would not go into the direction of ground water. Another way of leachate handling are: landfill isolation, in order to prevent the inflow of external water and the outflow of leachate water; site selection of an area, which has a good capability of pollutant neutralization; leachate recirculation to be redirected to the solid waste pile; flowing the leachate to domestic waste treatment system and leachate processing with a certain system. Some processing techniques that are often to be used are: physical-chemical processing, such as coagulation-flocculation-settling; aerobic processing (activated sludge, stabilization pond or aeration pond); anaerobic processing, such as stabilization pond and utilization of sorption characteristics, such as active carbon. The aerobic stabilization pond system is suitable for Indonesian condition due to the availability of sunlight, simple, relatively cheap and their capability of BOD reduction above of 90% and COD reduction of above 80%.Kata Kunci : Leachate, TPA sampah, teknologi pengolahan.

Tarupa village’s a subdistrict located in a tidy and peat area. The community living in tarupa use surface water of river as the main clean water resource. The surface water is influenced by the tide of sea water. The surface water taste is very salty (TDS12000ppm). The use of rain water as the second alternative is very limited, i.e it is only in rainy season. To deal with the chronic problem, such as the lack of clean water supply, it needs an appropriate water treatment technology. The suitable water treatment system is a combination of conventional and advanced technology. Desalination, such as Reverse Osmosis must be involved to reduce salinity of the raw water. A complete process includes the pretreatment and advance treatment. The pretreatment are oxidation and some common filtrations. The advance treatment is a molecular filtration using a membran which the principal is reverse osmosis pressure. If the pilot water treatment plant is avalaible in Tarupa in Takabonerate, the clean water supply will not be a serious problem.

Clean water supply is still a very difficult problem for small villages, especially in County Ende, NTT. Three villages, ie Detukeli, Ndetundora I and Ndetundora II, are the examples. The real problem is the settlement living in the area which do not have enough potential of water resources.There are some potential surface water resources, but they are located more than 3 km from the village settlement. One of the potential rivers is so separated by a big hill, that the people have to walk for a long distance to reach the clean water resource. To solve the problem, it is very important to develop a transmition piping, including the distribution net and a hidram water pumping system. To construct a complete water supply system needs a lot of investation. For only Village Detukeli as an example, it needs approximately almost 2 thousand million rupiahs.
