Abstract

The shell of picungfruit seedscontainsa quite high amount ofactivated carbonwhich isnot yet been optimally utilized. This research aims to utilized theshell of picung fruit seeds asmain ingredientinthe making of charcoal briquettes and to get the best concentration of tapioca adhesive.The method of this research used Completely Random Design (CRD) whichconsist of5treatment and eachtreatment was repeated 3 times.The treatmentofP1 was 97%: 3%, P295%: 5%, P393%: 7%, P491%: 9%,P589%: 11%. continued with Duncan New Multiple Range Test (DNMRT) at 5% level. Result of the analysis showed that the variation range of tapiocaadhesive of charcoal briquettes was significantly effected on moisture, ash, combustion rate level, and the level of the substance evaporation, and the heat  value. Based on this research, the best treatment was ratio of charcoal and tapioca adhesives, wich were P1 (97% : 3%), average content of moisture 2.92%, ash 3.52%, combustion rate 43×10-3, substance evaporation 15.32%, and heat value 6.554 cal/g. Keywords: Briquettes, tapioca starch, seedsshellpicung fruit

Abstract

Bio-charcoal briquette is one of the biomass fuel. Biomass used in this research were rice straw and rice husk. The aim of this research was to obtain the best composition of bio-charcoal briquettes using rice straw and rice husk that meet the standard quality of briquette. The research used Completely Randomized Design with five treatments and three replications. The treatments were ratio of rice straw and rice husk 90:10, 75:25, 50:50, 25:75, and 10:90. Data obtained were analyzed using Analysis of Variance and followed by Duncan’s Multiple Range Test at 5% level. The result showed that ratio of rice straw and rice husk in each treatment significantly affected moisture, ash, density, bulk density, calorific value, fuel, and volatile matter. The best treatment was a bio-charcoal briquettes which made from ratio rice straw and rice husk 10:90 with moisture content 9.4543%, ash content 30.2718%, density content 1.0110 g/cm3, crushing strength content 0.0120 kg/cm2, calorific value 3794.3530 cal/g, fuel content 0.0081 g/second, and level of volatile matter 0.0198%.Keywords : Bio-charcoal briquette, rice straw, rice husk
