Virgin Coconut Oil atau minyak kelapa murni mengandung asam lemak rantai sedang yang mudah dicerna dan dioksidasi oleh tubuh sehingga mencegah penimbunan di dalam tubuh. Penelitian ini mencoba memproduksi minyak kelapa murni/VCO dengan cara fermentasi dan menggunakan berbagai variasi konsentrasi starter kultur kering BAL. Penggunaan kultur kering BAL memiliki beberapa keuntungan antara lain bisa disimpan dalam waktu yang lama pada suhu dingin, mudah diaplikasikan serta efesiensi biaya. Tujuan dari penelitian ini adalah untuk mengetahui jumlah persentase Free Fatty Acid (FFA) pada proses fermentasi minyak kelapa murni. Karena semakin rendah nilai FFA yang dihasilkan semakin tinggi pula kualitas minyak yang dihasilkan. Penelitian ini menggunakan Rancangan acak lengkap dengan 1 faktor yaitu konsentrasi kultur kering BAL, dengan perlakuan penelitian sebagai berikut: A1 = 5 gram kultur kering BAL; A2= 10 gram kultur kering BAL; A3 =15 gram kultur kering BAL; A4 =20 gram kultur kering BAL. Berdasarkan hasil penelitian  mengenai kadar asam lemak bebas pada minyak kelapa murni (VCO), terlihat bahwa hasil rata-rata kadar asam lemak pada perlakuan A1-A4  berkisar antara 0,12 % sampai dengan 0,28 %. Namun pada A4 (Kultur Kering BAL 15 gram), kadar ALB pada minyak kelapa murni (VCO) masih tinggi atau tidak memenuhi standar SNI yaitu > 0,2 %.

The clove leaves are part of the clove plant which rarely used, and if you look at them, the clove leaves have active compounds that can be functioned as antibacterials. Meanwhile, Virgin Coconut Oil or called VCO, is processed from coconut milk as the essential ingredient, and if it is not processed correctly, VCO will usually have a short shelf life or can be damaged quickly. This study aims to determine the quality of VCO by adding clove leaves in its processing. Based on the results of the study, it can be seen that the quality of VCO with the addition of clove leaves for the indicator of water content and the free fatty acid number is not following the Indonesian National Standard (SNI). In contrast, the indicator for the VCO peroxide number with a mixture of clove leaves has good quality according to the SNI standard. Based on the results of the study, it can be seen that the quality of VCO with the addition of 100 grams of clove leaves for indicators of water content and fatty acid numbers, namely 2.9% and 0.69%, is high or above the SNI standard limit. In comparison, the quality of VCO with the addition of 100 grams of clove leaves with indicators a peroxide value of 0.7 mg ek/ kg or less than 2 mg ek/kg has good quality based on Indonesian National Standard. Keywords: Quality, VCO

<p>An accurate kinetic data has been considered as main substance in hydrolysis reaction. This research was conducted at the laboratory of processing of Indonesian Palm Crops Research Institute (IPRI) during June-July 2015. The objective of the research was to obtain the optimum condition of hydrolysis of VCO and the data of reaction kinetics (the reaction rate constant (k), the activation energy (Ea), and the reaction kinetics equation). Virgin coconut oil hydrolysis was done in two stages, the first step was the determination of the ratio of VCO:water (1:3; 1:6; 1:9; 1:12), the second step was the evaluation of reaction temperatures (60°C, 70°C, and 80°C). The determination of the optimum condition was based on the result of free fatty acid content and the values of the reaction rate constant. The free fatty acid content was measured by acid-base titration, meanwhile the reaction rate constant was determined by the equation –ln(1-XA)=kt. The results showed that the hydrolysis of VCO using ratio of VCO:water 1:12 produced higher content of FFA (0.11%) compared than others. The ratio of VCO:water 1:12 was then used to obtain the optimum temperature of hydrolysis. The optimum temperature of hydrolysis was 80°C with 0.14% of FFA, the reaction conversion was 0.88, and the reaction rate constant was 0.27 hour-1. The water consentration and reaction temperature influenced the FFA content, reaction conversion, and the reaction rate constant. The best condition of VCO hydrolysis using 1% of hydrochloride acid catalyst was on ratio of VCO:water 1:12, reaction temperature 80°C for 8 hours. The relationship between the reaction rate constant and temperature, follow Arrhenius equation k = 1,62 x 1015 e -25831/RT. Free fatty acid and glycerol are extensively used as raw materials in the manufacture of products such as detergents, cosmetics, surfactants, and pharmaceuticals.</p><p align="center"><strong>ABSTRAK</strong></p><p>Hidrolisis dapat berjalan baik apabila menggunakan data kinetika yang tepat untuk mendapatkan produk yang diinginkan.
