Abstract

Used cooking oil is oil left over from frying that can no longer be used for frying because it has decreased
nutritional value and has a negative impact on health. Used cooking oil can still be used as an example as a
raw material for making soap after being treated with used cooking oil. This study aims to make soap from
used cooking oil as raw material after being adsorbed using activated carbon from oil palm shells. The stages
of this research are 1). Making activated carbon from oil palm shells, 2). Applying activated carbon from
palm oil shells to used cooking oil, 3). Making soap from used cooking oil that has been adsorbed with
activated carbon from oil palm shells and 4). Testing the quality of soap, namely moisture content, soaping
number and foam quantity. The results showed that the characteristics of the soap produced with an average
water content of 7.5% (SNI 196-206 Max 15%), Sapling Number 196.90 mg / gr (SNI 196-206 mg/gr) and the
amount of foam 1, 58 ml. Soap made from used cooking oil as raw material that has been adsorbed using
activated carbon from oil palm shells in accordance with SNI 196-206 mg/gr.
