Analysis of Energy Potential of Biomass Electricity from Leaf Waste by Using Briquette Method

摘要

This research is persuaded by two conditions, particularly the lack for expanding electrical energy and the production of abundant leaf litter in urban forests that involve rapid handling. The case study was conducted in an urban forest area at the University of Indonesia Depok campus which has an area of 320 hectares with leaf waste data for three months of research of 103,885 kg. This research aims to obtain a substantial potential electrical energy that can be brought about by the waste leaf by transforming it through the method of briquettes and employed as feed for power generation. The briquette sample is carried out with a mix of charcoal blend of leaves and adhesive. The potential of biomass electricity is influenced by parameters such as the calorific value, the efficiency of the prime mover, and the efficiency of the generator. From the research, it was found that waste briquettes with a mixture of charcoal and adhesive 3: 1 provided heat energy of 3,179.29 cal/kg, and the potential of electric energy achieved from 1 kilogram of leaf waste briquettes was 0.37 kWh/kg. The potential for energy provided is substantial enough, so it can be applied as an alternative fuel for biomass power plants.
