Daftar Isi:
- Dependence on fuel oil brought Indonesia to the energy crisis seriously. One way to reduce dependence on fossil energy is to develop alternative renewable energy sources, for example, developing energy from farm waste. One of plantation waste that can be developed as a fuel is coffee peel. Positive value of bio-fuels is having an environmentally friendly nature and availability of raw materials are always available. This research was conducted in laboratory scale, and using robusta coffee peel as row materials. This research process through four phases, there are, raw materials preparation, pyrolysis, making briquettes, and performance test. Control variable in this research is pyrolisis temperature that 450°C. Independence variable, charcoal powder that passes 15 mesh, 25 mesh, 50 mesh, 80 mesh and 120 mesh filter, and variations in the composition of adhesive and charcoal powder 1:1, 1:3, 1:5, 1:8, 1:10. Dependent variable, there are moisture content test, ash content, carbon content, volatile matter, calorific value. The research concluded that coffee peel waste can be used as raw material for making fuel briquettes as an alternative to fossil energy, and obtained optimal conditions for the manufacture of briquettes with coffee peel waste as raw material is pyrolysis temperature of 450 ° C, particel size of 120 mesh, with a ratio of adhesive and charcoal powder 1:8. In that condition, characteristics of the briquettes obtained as follows: water content 6,34%, ash content 7,6%, volatile matter 5,34%, bound carbon content 81,72%, and calorific value of 5626,183kalori/gr. All the above characteristics meet the SNI standards SNI (SNI.01-6235-2000).
