Utilization of Gendruwo waste (Sterculia foetida Linn.) as briquettes

Abstract

Gendruwo plant (Sterculia foetida Linn.) or more commonly known as Kepuh is a plant species in Indonesia that origination from East Africa, Asia and Australia. This plant can be used as biofuel raw material in the form of biodiesel and bio-oil. Gendruwo plant seeds contain vegetable oil which consists of fatty acids namely stercylat acid (C19H34O2). The seeds that have been extracted into biodiesels leave the residue or waste in the form of gendruwo seed pulp. From the analysis, the remaining extract or debris can still be used as fuel because it contains the remaining fatty acid compounds. These gendruwo dregs can be used as coal substitute briquettes. Gendruwo seed waste briquettes have quality advantages than coal briquettes or coconut shell briquettes because they have longer coal resistance, which are environmentally friendly and also produce a better heat.
