Abstract. The disposal of laundry wastewater into the septic tank and the condition of the septic tank in the IPLT Balai PIALAM service area which does not meet the quality standards caused the fecal sludge product from the IPLT Balai PIALAM difficult to dry because of the high water content and it still emits pungent smell. IPLT Balai PIALAM has carried out the process of increasing the operating unit and dewatering process unit but has not yet obtained optimum dewatering results. Therefore, it is necessary to optimize the chemical conditioning process to increase dewatering efficiency. Chemical agent used in the process are alum, lime, and a combination of alum and lime. The purpose of this study is to analyze the effect of increasing the dose of chemical agent that can increase the efficiency of sludge dewatering in IPLT Balai PIALAM as well as assess the type and optimum dosage of chemical agent that used in the chemical conditioning process. The parameters used in this study are water content, TSS, TS, SRF, and CST in faecal sludge. The result of chemical conditioning optimization based on the study is the type of the most optimum chemical agent which is the combination of alum and lime ratio of 1:2 with an optimum dose of 14 g/L that can reduce the water content in the sludge from 90,14% to 64,68%, TSS from 73.000 to 6.915, TS from 102.950 to 13.620, CST from 90,29 to 22,4 seconds, and SRF value from 6,69 x 1010 to 1,23 x 1010 m/kg.
