Karakterisasi dan Aplikasi Briket Arang dari Cabang Tiga Jenis Kayu Mangrove

Abstract

Charcoal briquettes are one of the alternative energy sources to reduce dependence on fossil fuels, including to meet the needs of the global market. This study aimed to evaluate the characteristics of charcoal briquettes made from branches of three mangrove species and analyze the influence of the presence of bark and different species of mangrove wood branches on the properties of charcoal briquettes. Charcoal briquettes are made from branches of three mangrove species, namely Rhizophora mucronata, Bruguiera gymnorrhiza, and Bruguiera sexangula. The production process begins with converting branch wood (with bark and without bark), followed by carbonization by pyrolysis method, mixing with starch adhesive, and manufacture of cylindrical charcoal briquettes measuring 5 cm by 15 cm. The results of the study showed that mangrove wood branches are very suitable for use as raw materials for charcoal briquettes. The resulting charcoal briquettes have met SNI 01-6235-2000 standards for moisture content and calorific value. Statistically, there are no significant differences in the properties observed among charcoal briquettes, either due to the presence of bark (with and without bark) and the type of mangrove wood. The results show that mangrove wood branches can meet the industry standards of charcoal briquet-making and the utilization of mangrove forests as a source of raw materials will be sustainable because only branches alone can be utilized.
