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

<p>Abstrak</p><p>Proses penggorengan akan menyebabkan perubahan mutu minyak akibat reaksi hidrolisis, oksidasi dan proses termal. Penelitian ini bertujuan untuk mengetahui perubahan mutu  minyak kelapa dan minyak sawit selama penggorengan. Minyak kelapa dan minyak sawit masing-masing digunakan untuk menggoreng kentang pada suhu 170°C selama 15 menit. Minyak tersebut digunakan untuk 3 kali penggorengan. Pada akhir penggorengan dilakukan pengambilan sampel minyak untuk dievaluasi kadar air, kadar asam lemak bebas, bilangan peroksida dan bilangan TBA (Tiobarbituric acid). Hasil penelitian menunjukkan bahwa sebelum penggorengan minyak kelapa dan minyak sawit memiliki kadar air yang hampir sama, tetapi kadar asam lemak bebas, angka peroksida dan TBA minyak kelapa lebih rendah dibanding minyak sawit. Selama penggorengan minyak kelapa dan minyak sawit menunjukkan pola perubahan kadar air yang hampir sama. Pada 1 kali dan 2 kali penggorengan kadar asam lemak bebas, angka peroksida dan angka TBA minyak kelapa dan minyak sawit cenderung berfluktuasi. Pada 3 kali penggorengan minyak kelapa memiliki kadar asam lemak bebas,  angka  peroksida  dan  angka  TBA  yang  lebih  rendah  dibandingkan  minyak  sawit.  Hasil  yang  diperoleh menunjukkan   bahwa   minyak   kelapa  lebih   stabil   terhadap   reaksi   oksidasi   dibanding   minyak   sawit   selama penggorengan.</p><p> </p><p>Pattern of Coconut Oil and Palm Oil Quality During Frying</p><p>ABSTRACT</p><p> </p><p>Frying was a process which affected the quality of oil due to hydrolysis, oxidation and thermal reactions. The aim of the research was to study the quality pattern of coconut oil and palm oil quality during frying. The oils were utilized to fry french fries at 170°C for 15 minutes and then used in frying process for 3 times. Samples of oil were taken at the end of each frying period and analyzed for its moisture, free fatty acid, peroxide and TBA (tiobarbituric acid) values. The results showed that, coconut oil and palm oil having similary moisture content before and during frying. Otherwise free fatty acid, peroxide and TBA values at coconut oil lower then palm oil. During 1 and 2 times of frying period these two oils showed fluctuation in free fatty acid, peroxide and TBA values. During 3 times of frying, coconut oil contained free fatty acid, peroxide and TBA value lower than palm oi. Thus, we consider that coconut oil was more stable to oxidation compared to palm oil during frying</p>

Mandar coconut oil is one of the coconut processed products, which has become superior product in West Sulawesi especially in Majene regency. Unfortunately, the Mandar coconut oil can’t be used more than a month because the water content and free fatty acid content of the oil have exceeded the maximum standard of SNI, so it can adversely affect on health. On the other hand, the existence of rice husk in Indonesia itself especially in West Sulawesi has not received attention and is limited to a few needs such as for ash or livestock feed, and the rest is thrown away. This research aims to determine the effect of rice husk ash addition on the increasing of Mandar coconut oil quality. Completely randomized design was used in this research with 6 rice husk ash concentration variation levels i.e. 0%, 5%, 10%, 15%, 20% and 25%. The result shows that the addition of rice husk ash with 10% to 25% can reduce the water content of the oil until the quality standard of SNI is full filled. The highest reduction of water content was reached with 25% of rice husk ash concentration with 81% of reduction percentage. While, the addition of rice husk ash with 15% concentration can reduce the free fatty acid content of Mandar coconut oil until 32%.

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
