Peningkatan Kualitas Biobriket dari Tandan Kosong Kelapa Sawit Melalui Torefaksi dengan Penambahan Co-Firing dari Tempurung Kelapa dan Sludge CPO sebagai Perekat

Abstract

Indonesia is one of the world's leading producers of crude palm oil. This large production, however, creates a huge quantity of waste, one of which is empty palm fruit bunches. These empty fruit bunches have a high potential for use as a renewable energy source, such as in the creation of briquettes employing the torrefaction process with co-firing addition, with the goal of increasing their heating content. Furthermore, the goal of this research is to determine the best composition of co-firing with variation adhesive addition for increasing heating value and to compare the heating value, ash content, and volatile matter content of various compositions of co-firing. The study began with the preparation of raw material samples of empty palm fruit bunches and coconut shells. Torrefaction at 300°C for one hour is utilized. The torrefaction results are produced into briquettes with a variety of compositions of empty palm fruit bunches and coconut shells. CPO sludge is also used as an adhesive with concentrations of 20% and 30%. The briquettes produced with an addition co-firing from coconut shells fulfilled SNI requirements such as heating value, moisture content, volatile matter, and ash content. The best briquette quality is composed of 40% empty palm fruit bunches and 40% coconut shell, with a heating value of 6241.26 cal/g, 3.15% moisture, 5.8% ash, and 9.9% volatile matter.
