Bio-briquettes Innovation Co-FES (Coconut Fiber and Egg Shell) as the Eco-Friendly Fuel with Pressure Giving Methods for Indonesian Energy Fuels Challenge

Problems about energy cannot be separated from human life. Therefore, alternative fuels are needed that cheap and eco-friendly for small industry and home industry. One of them is using alternative energy briquettes from biomass waste. So, the purpose of this research is to find ways of making Bio-briquette "Co-FES" from the mixture of coconut fiber and shell eggs, to determine the effect of pressure from pressing process with quality of Bio-briquette, and to determine the ratio of Bio-briquette experiments results with the Indonesian National Standardization (SNI) briquettes. There are there stages to make Bio-briquette from coconut fiber and egg shell. First step is pre-treatment stage, it is stage to prepare a raw material by drying and charing coconut fiber and eggshells. And the next stage by mixing all the raw materials of coconut fiber and egg shells plus a starch adhesive with a ratio of each of 3: 1 and 2: 1. Then, insert the material that has been mixed into the Bio-briquette mold with manual pressure, a pressure of 15 kg / cm2, 30 kg / cm2 and 45 kg / cm2. The third stage is analysis stage includes the analysis of density, analysis of water content, ash content analysis, analysis of the mass loss and calorific value analysis. From the experiments it can be concluded that higher pressure, the density value is also higher. From variable density obtained optimum pressure is at a pressure of 45 kg/cm2 on the material composition ratio of 2: 1 at 0.2654 g/cm3 according to SNI Bio-briquette No. 1/6235/2000 is ≤ 0.4507 g/cm3.
