Pemanfaatan Biji Kepayang (Pangium Edule Reinw) Menjadi Biodiesel Dan Biopelet Dengan Menggunakan Alat Screw Oil Press Machine

Sari

Energy is a major need in all aspects of life in all countries. The increasing population on earth, the number of needs is also increasing, so that energy consumption also increases which causes the availability of reserves of non-renewable energy such as petroleum depleting. One solution to reduce dependence on fossil energy is the discovery of alternative fuels, one of which is biopellet. The purpose of this research is to get biopelet from seed meal of Kepayang which has a compact structure and does not break easily, to obtain optimum conditions in the form of temperature and screw rotation from raw material of seed meal of kepayang with a cold oil press machine, to obtain the best quality biopellet according to the Indonesian National Standard (SNI 8021-2014), reduce the impact of environmental pollution due to waste from seed meal of kepayang. The number of biopellet samples tested in this research were 12 samples with variations in temperature parameters and screw rotation. Temperature variations in this research were 100ᵒC,150ᵒC,200ᵒC and 10 Hz,15 Hz,20 Hz,25 Hz screw turns at each temperature variation. From the results of the research, it was found that the best variation of biopellet was a sample at a temperature of 200ᵒC with a 25 Hz screw rotation. This variation results in a heating value of 5752.6780 cal/gr, moisture content of 1.8692%, density of 1.4216 gr/cm3, ash content of 2.7523%, volatile matter 75.5818%, and fixed carbon 19.7967% . The heating value, density, moisture content, volatile matter and fixed carbon have fulfilled in SNI 8021 - 2014 standard, but the ash content only have fullfilled in PERMEN ESDM NO.47 standard and several country standards such as England, Japan, France and America.
