Abstract:

Research on the variation of contact time of the candlenut shell charcoal purification process used cooking oil has been done. This research aims to determine the ability of candlenut shells in used cooking oil purification. The time variation used is 30, 40, 50, and 60 minutes. The results showed that the activation results candlenut shell charcoal meet SNI 06-3730-1995, while the results of purification used cooking oil at a time of 60 minutes can result in a reduction in free fatty acids amounting to 98.0 %, a reduction of 85.6% peroxide grade, and reduction in water content of 72.1 % of the samples tested. Results purification used cooking oil is in compliance with the maximum standards of quality cooking oil that net in SNI 01-3741-1995.
