Pengaruh Suhu Dan Waktu Torefaksi Terhadap Kualitas Pelet Kulit Batang Sagu Serta Emisi Gas Co Dan Co2 Dari Hasil Pembakarannya

Sago bark is biomass waste produced from the sago processing which not been utilized optimally. The lignin content in sago bark is quite high, around 32.29%, which has the potential to be used as biomass pellets. The water content and calorific value of sago bark pellets still do not meet standards, through the torrefaction process the quality and quality of the pellets can be improved. This research aims to analyze the physical characteristics of pellets based on variations in temperature and torrefaction time, combustion characteristics, CO and CO2 emissions produced and to determine variations in the best pellet torrefaction. The method in this research is to vary the temperature and time of pellet torrefaction over a temperature range (280℃, 300℃ and 320℃) for (20 minutes, 30 minutes and 40 minutes), then burn the pellets using a TLUD type gasification stove and test emissions using CO Meters. The research results show that the temperature and time of torrefaction influence the results of the physical characteristics, combustion characteristics and emissions produced. The physical characteristics of the best torrefaction pellets at KPA5 (300℃, 30 minutes) are hydrophobic pellets with a water content of 2.39%, ash content of 4.98%, volatile matter 60.38%, fixed carbon 32.25%, calorific value of 4855 cal. /g and a density of 0.96 gr/cm3, this value meets pellet standards based on SNI 8675:2018. The combustion characteristics of KPA5 include ignition time, combustion time, combustion rate and combustion efficiency of 60 seconds, 3450 seconds, 0.1467 gr/second and 0.04 with a combustion temperature of 564℃. The CO and CO2 gas emissions of the KPA5 sample were 43.86 ppm and 979.91 ppm respectively. The CO2 gas emission test results have met quality standards based on PERMENKES No. 2 of 2023.

Keywords: Sago bark pellet, torrefaction, physical characteristics, combustion characteristics, CO and CO2 gas.
