Abstract

The development of biomass has been assumed as an important issue in the past several decades and would remain to be attractive in the future due to its clean, renewable, and carbon–neutral properties. Biomass is one of the most important renewable energy resources in the world. In recent decades, the utilization of biomass has dramatically increased. There were many reasons. First, biomass is a renewable resource, because of the availability of biomass is unlimited, and its regenerative process runs well. Second, the extraction of biomass energy can be carried out more flexibly. The biomass can be burned directly without high technology. Biomass bio-briquettes are often used as an energy source for cooking purpose and in some industries. The bio-briquettes are produced by densification of waste biomass using various processes. In this the study manual densification of bio-briquettes was tested by three different binding agents; cassava flour, sago flour, and starch flour. The objective of this study was to compare different binding materials in the production of Empty Fruit Bunch (EFB) bio-briquettes between binders. The 2% is used as a binder in a mixture with EFB fibre. The ratio of the use of water as a diluent between the fibre and the adhesive is 1 : 5. Samples of solid cylindrical shape diameter 4 cm and 5 cm high and density sample is 0.8 g/cm3. The pressure is used to generate samples specified in the mold volume. The volume of the cylinder is 62.8 cm3. The adhesive cassava with a percentage of 2% is able to provide power to the sample mechanically by a drop test at a height of 1.20 m. The result show that the sample binder cassava have fuel calorific value average is 3661 cal/g, binder of starch 3584 cal/g and sago 3537 cal/g. Results indicated that sample binder cassava flour have fuel calorific value higher than other samples.
