UJI KARAKTERISTIK MINYAK BIJI KESAMBI (Schleichera Oleosa) ASAL NOEMUTI TTU SEBAGAI BAHAN BAKAR ALTERNATIF

Abstract

Research was conducted on the Characteristic Test of Kesambi Seed Oil (Schleichera oleosa) from Noemuti, TTU as an Alternative Fuel. The purpose of this study was to determine the characteristics and feasibility of kesambi seed oil by the continuous extraction method or soxhletation using n-hexane as a solvent. The obtained oil extract is purified through a degumming process, a neutralization process to separate fatty acids and phosphides, and a bleaching and deodorizing process using an adsorbent. Observations were made in the form of oil yield and physical and chemical properties of kesambi oil. The results obtained are: an oil yield of 69%; the physical properties are clear yellow in color; specific gravity of 0.85 gram/mL; refractive index of 1.56, melting point of 5–31°C; and chemical properties are acid number of 4.18 mgKOH/gr.sample; saponification number of 34.5 mgKOH/gr.sample; peroxide number of 1.7 meq O₂/Kg sample. From the results obtained, it can be concluded that pure kesambi oil from Noemuti, TTU can be used as biodiesel if viewed from its characteristics.
