The objective of this study is to improve the quality of used cooking oil by rice husk ash(RHA). Several variabels that will effect of recovery used cooking oil such as of weight and contact time variation of RHA. Subsequently, the used cooking oil was filtered to analysis the change of colour intensity, free fatty acids (FFA), peroxide value (PV), cholesterol, triglycerides, LDL and MDA were observed.RHA adsorbent surface characteristic were analyzed with SEM, functional groups Si-O-Si with FTIR and the content of silica in RHA by XRF. The results showed that the variation of the optimum recovery condition in weight of RHA is 20 g and contact time for 4 weeks it could reduce the value of the absorbent colour is 69.80,%, FFA is 74.42%, PV is 69.22%, cholesterol is 17.09% , triglycerides is 46.63 %, LDL is 33.24%, and MDA is 24.02% respectively. Based on the data obtained, it can be concluded that all the parameter tests under the requirements of SNI and the US National Cholesterol Education Program (NCP) -E2001 (maximum) and adsorbent RHA can improve the quality of used cooking oil.
