Abstract

Utilization of biogas sludge waste from cow dung into briquettes is an alternative to reduce the use of fossil fuels. In the manufacture of briquettes made from biogas sludge, molasses is used as an adhesive which is a by-product of a sugar factory. In this study, variable compression briquettes with variations of 10, 15, 20, and 25 mm were used and further testing was carried out on the moisture content, ash content, and calorific value of the briquettes. The effect of briquette compression on the water content of the best briquettes according to the SNI standard (less than 8%) is at 10 mm compression variation with a moisture content value of 6.03%. Meanwhile, the effect of pressing briquettes on the ash content and calorific value is still above the SNI standard and requires further study.

Abstract

Waste’s dynamic problem will always be present in humans life and even get increasing each day. Waste generated from various kind of human activities and it will cause serious problem if it is not handled properly. One among many waste types which mostly produced from humans daily activities is organic waste and the concrete example is vegetable trash. Vegetable trash generated in large amount everyday that the treatment of this trash is important to be carried out. Also, vegetable trash is a source of biomass which can be converted into renewable energy source, that is biogas. This research aims to collected literature references (review) of vegetable trash conversion into biogas by adding with cow dung and draw conclusion about optimum composition of mixture of cow dung and vegetable trash which obtain highest methane gas (CH4) concentration. Cow dung is known as potential biogas raw material for its high cellulose content after digested in cow’s stomach that its is easier broken down by methane composing bacteria in methanogenenis process to produce methane gas (CH4). The variables used in this research are mass ratio between cow dung (KS) and vegetable waste (SS) variation of 100:0; 75:25; 50:50; 25:75; and 0:100 with addition of EM4. Literature review give conclusion that optimum composition mixture in biogas production process is 70% cow dung and 30% vegetable trash.
