The Faculty of Nursing of Universitas Indonesia in Depok uses groundwater as the source of clean water in a large amount: 2.115.240 liters in 2018 and 22.010.960 liters in 2019. One of the alternatives for reducing groundwater use is to utilize surface water in the surrounding area of the campus, such as Lake Agathis. For the lake water to be used as the source of clean water, it needs to be processed first using a clean water provision system (CWPS). The CWPS is designed to contain two slow sand filter units, with the media consisting of 60 cm-thick silica sand and 40 cm-thick granular activated carbon in each unit. The CWPS is also equipped with one unit of shore intake, two units of suction well, one transmission duct, one unit of disinfectant and reservoir, and two filter media cleaning units. Based on a literature review from several journals and the results from this experiment, the designed slow sand filter with the previously determined thickness can reduce iron contents by 95,07%, manganese contents by 97,09%, and fecal coliform contents by 99%. The designed CWPS can serve the needs of clean water of the faculty described before with a debit of 3,8 L/s until the year 2042.

Organochlorine pesticide is one of the pesticide that has high persistency and toxic. One of the attempt to degrade organochlorine pesticide using cheaper and easier way is using the slow sand filter technology. The research aimed to test the slow sand filter and to obtain the best filter media combination for degrading organochlorine pesticide. The experiment was conducted at the Laboratory of Pesticide and Toxicology, Laboratory of Plant Protection Biotechnology and Laboratory of Chemical and Soil Fertility, Faculty of Agriculutre, Padjadjaran Univeristy from December 2016 – May 2017. The experimental design used the observative and descriptive design with 8 treatments and repeated twice. P1 (activated carbon and gravel), P2 (sand and gravel), P3 (silica sand and gravel), P4 (activated carbon and zeolite), P5 (sand and zeolite), P6 (silica sand and zeolite), P7 (activated carbon, silica sand and zeolite), P8 (activated carbon, sand and gravel). The result showed that all treatments of slow sand filter were able to degrade organochlorine pesticide and the best filter media combination was from P7 with ability to degrade the pesticide level by 82,86%.Key words: slow sand filter, activated carbon, silica sand, sand, gravel, zeolite

Studies were conducted to evaluate the adsorption–desorption isotherms of a common dry cleaning solvent, perchloroethylene (PCE), in soils, peat moss, and granular activated carbon. The results obtained followed the Freundlich Isotherm, and the organic carbon content of the media was the most significant controlling factor in the adsorption–desorption process. The peat moss exhibited the highest residual saturation concentration for pure PCE amongst all the media tested. The desorption studies indicated that PCE had medium mobility in soil and was not significantly affected by moderate changes in pH. Key words: adsorption, desorption, Freundlich Isotherm, granular activated carbon, peat moss, perchloroethylene, soils.

The abundant peat water in Buluh Cina Village, Siak Hulu Subdistrict, Kampar is a natural potential that can be used for cooking and bathing purposes by processing peat water into clean water that is suitable for consumption. The purpose of this service activity is to treat peat water into clean water. The method used in this service activity is using coagulant and filtration technology. The optimal filtration and coagulant media used for peat water treatment consists of biosand filters with two media namely pumice and quartz sand. The dedication results reduce turbidity and color of peat water and reduce organic content, so that peat water is processed into clean drinking water. The lowest pH value before filtering is equal to 5.93 and the highest pH is found before filtering which is 6.23. This means that before filtering peat water is weak acidic. The lowest sample results after filtration with a slow sand filter that is equal to 6.42 and the highest pH after filtration of 7.5, which means that water is weakly basic. A good pH limit for water is 6.5 to 8.5 so this service proves that slow sand filters are considered effective enough to optimize water pH. Total dissolved solids (TDS) is one of the parameters for determining water quality, TDS shows the amount of solute solids in water. The result of peat water TDS is that the lowest TDS value before filtration is 46 mg / L and the highest TDS is found before filtering which is 49 mg/L. The lowest sample results after filtration with slow sand filter is 49 mg / L and the highest TDS after filtering is 83 mg/L.

Pekauman Ulu Village is one of the villages crossed by the Martapura river, where the water is used by  the people of this village for their daily activities. Pekauman Ulu Village is a densely populated area which is flooded every year. The water is very turbid with an unpleasant smell,  and consuming this water often makes some people get diarrhea. Thus, a simple technology is needed to treat this river water into clean water. This activity aims to build  Slow Sand Filter (SSF) units as a means of providing clean water for people in Pekauman Ulu Village. The activity is conducted in three parts: initial dissemination, training, and evaluation. Based on the survey done to the people joining the training, 95.25% of the people said that they were satisfied with the water being treated by SSF. As for the performance of the SSF itself, turbidity measurement of water samples showed that the turbidity of water filtered by the SSF unit reduced from an average of 41.7 NTU to 2.3 NTU.  It can be concluded that this community development program has successfully addressed the need for clean water for people in Pekauman Ulu Village.

Slow sand filter processing is done by separating raw contaminant water which is passed slowly on sand. Fluctuating raw water quality resulted in the schmutzdecke layer not growing optimally. Therefore, it is needed media that help the performance of the sand filter. One of the media used is geotextile. The geotextile is useful as a medium to optimize the growth of microorganisms in the schmutzdecke layer. Geotextiles have similar surface structures such as sand filters as well as their pores. The purpose of this study was to determine the effectiveness of adding geotextiles in reducing turbidity parameters, number of coli and COD. This study used slow sand filter reactor with a continuous flow system of 0.3 m3 / m2.jam for 7 days. Based on the research, the addition of geotextile media is quite effective and can improve the performance of slow sand filter. Percentage of turbidity removal reached 94.27%, coli 99.40% and COD 92.85%. COD values tend to be dynamic as raw water conditions. Geotextiles is quite helpful in growing a layer of schmutzdecke because the structure resembles sand so as to increase the number of bacteria bed filters.
