Abstract

Kepuh (Sterculia foetida L.) merupakan tanaman non-pangan penghasil minyak yang bisa dijadikan bahan baku pembuatan biodiesel. Penelitian ini bertujuan untuk mengetahui karakteristik biji, kandungan minyak, hubungan kekerabatan dan kualitas biodiesel dari biji kepuh (Sterculia foetida L.) di Kabupaten Badung, Kota Denpasar dan Rote. Penelitian dilakukan pada Desember 2016 – Mei 2017. Metode yang digunakan adalah pengamatan terhadap karakteristik biji, menganalisis kandungan minyak dan kualitas biodiesel dari minyak kepuh (Sterculia foetida L.). Kandungan minyak tertinggi diperoleh dari Kabupaten Badung dan Kota Denpasar yaitu di Monang-Maning 1 sebesar 41,13%, sedangkan terendah dari Rote di Oemasi 4 sebesar 14,80%. Hubungan kekerabatan antara karakteristik biji dan kandungan minyak terbentuk 2 kelompok dengan indek similaritas 93,5%. Kualitas biodiesel di Kabupaten Badung dan Kota Denpasar memiliki angka asam yaitu 0,34 mg-KOH/g dan Rote yaitu 0,44 mg-KOH/g, angka iodin di Kabupaten Badung dan Kota Denpasar yaitu 44,41 dan Rote yaitu 48,53. Angka penyabunan di Kabupaten Badung dan Kota Denpasar yaitu 187,93 dan Rote yaitu 194,94, angka setana di Kabupaten Badung dan Kota Denpasar yaitu 64,02 dan Rote yaitu 61,92. Kadar air di Kabupaten Badung, Kota Denpasar maupun Rote 0,2 dan viskositas di Kabupaten Badung dan Kota Denpasar 12,23 cSt dan Rote 9,22 cSt. Kualitas biodiesel diperoleh telah memenuhi ketentuan SNI 2015, kecuali viskositas.

Abstract

Indonesia is a tropical country with an area of coconut plantation of 3.7 Ha. The fruits of this plant have been used as materials in the production of Virgin Coconut Oil (VCO). Such oil is known to contain higher Medium Chain Fatty Acid (MCFA) or Medium Chain Triglycerides (MCTs) than original frying oil. The MCTs of this oil is very useful to avoid obesity, to reduce total cholesterol as well as to function as anti-microbes. These have been considered as a cheap solution to solve health related problems. The main objective of this research was to produce VCO catalyzed by pure culture of Lactobacillus plantarum isolated from a commercial VCO (Vici’O) combined with enzymes extracted from pineapple fruits. The study was conducted at the laboratory of Microbiology, Faculty of Mathematics and Sciences, Udayana University. The study was started with isolation and identification of Lactobacillus sp. from a commercial VCO. The VCO production method combined the two starters of Lactobacillus isolates (at concentrations of 0 to 10% v/v) and pineapple juice with various volumes (0 to 60 mL). In the first stage of the project, 3 potential Lactobacilli isolates (Sp1, Sp2, and Sp3) were successfully isolated and were confirmed to be Lactobacillus sp. In the main experiment, combination of 10% v/v Lactobacillus starter and 60 mL pineapple juice produced the highest VCO yield (43,17% v/v) with improved organoleptic properties, lower water content, lower saphonification, and lower peroxide than that specified by SNI No 7381: 2008.
