Abstract

Palm oil mill solid waste resulting from CPO production process is channeled into pond waste (Cooling Pond I). It is usually thrown to the ground so that it can contaminate the environment. This study was aim to utilize the oil palm waste as briquettes. Briquettes is one of the alternative to replace oil. Research was done by completely randomized factorial design with 2 factors i.e : density of air line (0,4, 0,8, and 1,2 cm) and Height of used cooking oil (2, 2,5, and 3 cm). Parameters observed were heating time, oil volume, and sootness. The results showed that the density of air line had a highly significant effect on the heating time, volume of oil and had no effect on the sootnes. Height of used cooking oil had a significant effect on sootness and had no effect on the heating time and volume of oil. The best treatment combination was L1T2 (0,4 centimeters density of air line and 2,5 centimeters Height of used cooking oil) with equipment heatimg time of 43,90 minute  and 1,79 gr sootness. Key words: Briquettes, density of air line, Height of used cooking oil centration, Oil palm solid waste.

Abstract

Waste Oil is the remains of frying oil that can not be reused. Therefore further processing is needed, one of them is being bar soap. The study was aimed to use waste oil into bar soap with extract of turmeric, aloe vera and papaya. The study was conducted at the Laboratory of Agricultural Engineering and Analysis of was done in Food Chemical Analysis Laboratorium Faculty of Agricultural in May 2014 to July 2014  by using a non-factorial completely randomized design. Parameters measured were water content, free fatty acid(FFA), alcohol insoluble part, and organoleptic test. The results show that turmeric, aloe vera, and papaya extract had no significant effect on water content, free fatty acid(FFA) and alcohol insoluble part. Keywords: Aloe vera, bar soap ,papaya, turmeric, waste oil
