Pengaruh Tekanan Pembriketan Dan Holding Time Terhadap Karakteristik Ketahanan (Durability) Briket Biomasa

Abstract

Abstract :
Densification of agricultural residues and wood waste into fuel briquettes could provide a relatively high-quality alternative source of fuel, especially where solid woodfuel resources were scarce. The important properties of briquettes affected the fuel-quality were their physical and chemical attributes. This research was conducted to know the effect of briquetting pressure and holding time on durability characteristic of biomass briquette. Biomass used was Kalimantan’s wood sawdust. Briquette was conducted by using a hydraulic machine press and briquette die was in form of cylinder with the inner diameter of 3 cm. Binder used was 10 % molasses and particle size of biomass sawdust 50 mesh. The variation of briquetting pressure used was 200 kg/cm2, 400 kg/cm2, 600 kg/cm2, 800 kg/cm2, and 1000 kg/cm2, whereas variation of holding time used was 5 s, 10 s, 20 s, 40 s, and 60 s. The testing of durability characteristic of briquette biomass was conducted based on standard of ASAE S269.4 DEC 96.From result of durability testing was founded that only parameter of the briquetting pressure had significant effect on durability rating biomass briquette.
