The effect of used lubricating oil volume as a binder on the characteristics of briquettes made from corn cob and coconut shell.

Abstract

The use of agricultural solid waste is one alternative source of energy substitutes, generally made into charcoal briquettes. In making charcoal briquettes, binder is needed to bind charcoal particles. In this study used vehicle lubricating oil was used as an alternative binder. Charcoal briquettes 600 mesh from corn cobs and coconut shell waste are made on the composition of raw materials of 75% corn coke charcoal, 25% coconut shell charcoal with a total weight of 100 grams. In each mixture, SAE 40 used lubricating oil was given with variations of 5 ml, 10 ml and 20 ml. Then each raw material weighing 16 grams was put into a mold measuring 2.2 cm in diameter and 6.33 cm high and pressurized by using a hydraulic press for 15 minutes until the briquette was formed. The results of the study showed that adding 20 ml of used lubricating oil gave the best characteristics of charcoal briquettes.
