Secara alami air memang sudah ada pada minyak. Pada tahap penetralan untuk pemurnian minyak kelapa sawit, air juga terbentuk akibat reaksi antara kaustik soda dengan asam lemak bebas. Tujuan penelitian ini adalah untuk mengetahui pengaruh kadar air pada pada proses pemucatan minyak kelapa sawit terhadap warna minyak dan terhadap asam lemak bebas. Penelitian dilakukan pada temperature operasi 70 °C dengan menggunakan pompa vakum (30-40 cmHg). Bahan pemucat yang digunakan tanah bentonite sebanyak 1,5% dari berat total keseluruhan minyak. Dilakukan dengan bantuan pengaduk dalam membantu penyerapan zat warna selama 30 menit oleh tanah bentonite. Hasil penelitian menunjukkan bahwa Kandungan air dalam minyak sangat berpengaruh terhadap warna minyak yang dihasilkan pada proses pemucatan. Bertambahnya kadar air, maka sangat berpengaruh terhadap warna minyak . Pengaruh kadar air juga terlihat terhadap asam lemak bebas (bilangan asam). Semakin tinggi kadar air minyak maka semakin besar harga bilangan asam minyak .   Water naturally exists in oil. In the neutralization stage for refining palm oil, water is also formed due to the reaction between caustic soda and free fatty acids. The purpose of this study was to determine the effect of water content on the bleaching process of palm oil on the color of oil and on free fatty acids. This study was carried out at an operating temperature of 70°C using a vacuum pump (30 - 40 cmHg). The bleaching material used by bentonite soil was 1.5% of the total weight of the oil. It was carried out with the help of a stirrer to help the dye absorption for 30 minutes by bentonite soil. The results showed that the water content in the oil greatly affected the color of the oil produced in the bleaching process. The increase of the water content greatly affected the oil color. The effect of water content was also seen on free fatty acids (acid numbers). The higher the water content of the oil, the greater the number of oil acid.

Improper of usage and storage of cooking oil can increase the water content on cooking oil. It can decrease of cooking oil quality and fried food that resulted from this cooking oil which then can cause health problems. This study aimed to determine of the waste cooking oil quality after it was adsorbed with charcoal from eggshell palm oil (Elaeis gunieensis). The quality was determined based on the free fatty acids, the peroxide value, and the water content of the waste cooking oil before and after adsorption. Determination of free fatty acids was used titration method while determination of water content was used gravimetric method. The result showed that the cooking oil quality contained 0.014% of free fatty acids, 1 meq.O2/kg of peroxide value, and 0.0003% of water content. The waste cooking oil quality without adsorption process was 0.042% of free fatty acids, 26 meq.O2/kg of peroxide value, and 0.0011% of water content. After adsorption process with 5, 10, 15, 20, and 25 gram of charcoal from eggshell palm oil into 100 mL of waste cooking oil, it was found that 15 gram of eggshell weight was the best adsorbent. In was condition, the free fatty acid was 0.0006%, the peroxide value was 2 meq.O2/kg, and the water content 0.0005%. It showed that the waste cooking oil quality become better after adding of charcoal of eggshell palm oil as the adsorbent.

Palm oil mill boiler ash is one of the substances that can be used as an adsorbent. The adsorbent can absorb certain components of a fluid phase, which before being applied needs to be activated using chemicals so that the effectiveness of the absorption is increasing. The use of adsorbents in CPO is quite effective in maintaining its quality. Several previous studies have studied the application of adsorbents in maintaining the quality of CPO. The purpose of the study was to utilize palm oil mill boiler ash as an adsorbent of several types of activators and to determine the effect of effective activator types in application to the quality of CPO oil. This study used a non-factorial completely randomized design with adsorbent activation treatment using H3PO4 and NaCl with a concentration of 10% and soaked for 24 hours. There are 3 parameters observed in the adsorbent application to CPO, namely free fatty acids, water content, and dirt content. The results showed that the adsorbent activated with H3PO4 was an effective adsorbent with a decrease in its free fatty acids up to 0.43%, water content decreased to 0.07%, but an increase in CPO impurities content of 0.24%. While the adsorbent activated using NaCl showed free fatty acids 0.22%, water content decreased by 0.03% and dirt content also increased by 0.24%. Keywords:   adsorbent activator, crude palm oil, boiler ash, H3po4, Nacl

Fruit stalk of chili pepper (Capsicum annum L.) so far is still an untapped waste. The content of active compounds in fruit and fruit stalk of chili pepper (C. annum L.) is known to have good antioxidant activity. The purpose of this study was to evaluate the extract of fruit stalk of chili pepper in inhibiting the oxidation of crude palm oil (CPO). In this study, the extraction of fruit stalk of chili pepper (C. annum L.) was carried out with n-hexane (from now on referred to as CHE) solvent and with ethanol solvent (from now on referred to as CEE). CHE and CEE were analyzed for total phenolic and flavonoid analyzes. Next, an evaluation of antioxidant activity was carried out using the DPPH method. The effectiveness test of adding the two extracts to the quality of CPO was carried out for ten days using a Completely Randomized Design (CRD) analysis. The parameters observed were peroxide numbers, free fatty acids, and iodine numbers. Data were analyzed by ANOVA and followed by a Least Significance Different (LSD) test. The results show that the total phenolic value is 0.257 mg QE/g dry weight in CEE and 0.003 mg QE/g dry weight in CHE. Total flavonoid values are 0.155 mg QE/g dry weight in CEE and 0.003 mg QE/g in CHE. IC50 values for DPPH test extract are 223.72 μg/mL in CEE and 953.77 μg/mL in CHE. The test results of the effectiveness of the two extracts against CPO show thin CEE, and CHE significantly (P <0.05) influences to CPO free fatty acids, peroxide number, and iodine number. Both extracts can protect CPO from oxidation. CEE is more effective in maintaining CPO quality for ten days with free fatty acid values (2.1%), peroxide value values 0.48 meq/kg, and iodine number 54.8. Furthermore, this result meets the CPO quality standard, according to SNI-01-2901-2006.

The processing of oil palm fresh fruit bunches (FFB), together with loose fruits, in the current mill operation contributes to oil loss and high free fatty acids (FFA), affecting crude palm oil quality. Fruit detachment induced by ethephon and ethylene may mitigate the current processing issues. This study shows that a 0.50% (v/v) ethephon application by the evaporation method induced the highest fruit detachment of 30.8 ± 1.1% after 24 h at room temperature, with the FFA content in the extracted crude palm oil at 0.34 ± 0.09%. Ethephon application was effective on bunches between 14 and 28 kg, and fruit detachment was higher in ripe and underripe bunches at 24.1 ± 0.9% and 23.2 ± 0.1%, respectively. A significant fruit detachment of 47.2 ± 2.4% was achieved when the bunches were also stripped mechanically, but the FFA content increased almost 4-fold, from 1.0 ± 0.2% to 3.8 ± 1.2%. The application of ethylene gas at 750 ppm yielded 29.4 ± 1.9% fruit detachment. The findings present the possibility of using ethylene as an indirect method for minimizing oil loss without increasing the FFA content in future crude palm oil production systems.

Quality is the overall characteristics and characteristics of a product or service whose ability to satisfy needs, both expressed and implied (Irwan & Haryono, 2015). In this era of increasingly competitive industrialization, every business person who wants to win the competition in the industrial world will pay full attention to quality. QCC is a new concept to improve the quality and productivity of industrial/service work. It is evident that one of the success factors of industrialization in Japan is the effective implementation of QCC. In this research journal, the quality of crude palm oil (CPO) levels is decreasing. There are 3 types of defects, namely levels of FFA (Free Fatty Acids), levels of Moisture (Water) and levels of Dirt (Stool). Of these three, the most dominant are FFA levels and Moisture levels. Free fatty acid content (FFA) of 158 samples tested contained 150 samples of free fatty acids (FFA) which were outside the company standard. Then followed by moisture content with a total defect of 45 samples from 158 test samples. At the level of dirt (Dirt) there are absolutely no samples that are outside the company's standards.
