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.

Coconut oil in West Kalimantan is still largely a traditional coconut oil because it has not gone through a refining process. To improve the quality of traditional coconut oil, the addition of activated charcoal can be used as an adsorbent so as to improve the quality of coconut oil. Activated charcoal can be made from materials that contain high carbon, one of which is a coconut shell. The purpose of this study was to determine the effect of adding activated charcoal to improving the quality of traditional coconut oil and the concentration of adding activated charcoal that produced the best characteristics of coconut oil. The research design used was a Randomized Block Design with one factor (coconut shell active charcoal concentration) 6 levels of treatment (0%, 1%, 2%, 3%, 4%, 5%) with 4 replications. The data obtained were analyzed using ANOVA (ɑ = 5%) if there was an influence followed by BNJ test (ɑ = 5%). The results showed that the addition of coconut shell activated charcoal with a concentration of 1% -5% to traditional coconut oil can significantly reduce free fatty acid levels. In addition, the addition of activated charcoal affects the sensory attributes of color and aroma to be better than the control (without the addition of activated charcoal). The best traditional coconut oil produced in this study is traditional coconut oil added with coconut shell activated charcoal with a concentration of 5% with chemical and sensory characteristics as follows: water content 0.138%, free fatty acid content 0.428%, saponification number 231, 9 mg KOH / g, color value 4,88, and aroma value 3,68.Keywords: adsorbent, activated charcoal, coconut oil, refining, coconut shell
