The Influence of Cast Ring Diameter toward Bagasse Biopellet Heat Value, Moisture, and Ash Content

Abstract

Bagasse is the dry residue of sugarcane extraction that can be used as an alternative energy, it is as the material of bio-pellet. Before it is casted into bio-pellet, the bagasse is dried by 600o C of temperature. Bio-pellet tested in this research is casted by horizontal pelletizer machine in determined time. The experimental research was conducted to bio-pellet to find out the effects of cast ring diameter toward heat value and water and ash contents. This research used experimental method with three variations of cast ring diameter. The data is obtained from the testing to variances of bio-pellet size. Result of the research shows that cast ring diameter influencing the three variables in bagasse bio-pellet. The significant influence shown by the smallest size of cast ring diameter. The small bio-pellet has minimum water and ash content, but it has optimum heat value. It shows that the quality of bagasse bio-pellet has met the SNI standard, but not with the quality of the ash content.
