Abstract

Along with the increase in the food and household industries, demand for raw materials for cooking oil continues to increase, causing shortages and increasing prices of cooking oil. This causes cooking oil to be used repeatedly. Cooking oil that has been used repeatedly is called used cooking oil which contains many carcinogenic compounds that can be harmful to health. Therefore, this research aims to purify used cooking oil using palm fiber carbon to improve the quality of used cooking oil. Nipa palm fiber contains hemicellulose and cellulose so it has the potential to be used as a carbon source using the calcination method and carrying out proximate tests such as ash content, vapor content and bound carbon content. Next, it is applied in the process of purifying used cooking oil using the adsorption method. After that, several properties of used cooking oil were tested, such as density, flow rate, acid number and saponification number. The results obtained in this research for the proximate test of palm fruit fiber at a temperature of 250-400℃ have met the SNI 06-3730-2021 standard. Nypa palm fiber carbon in used cooking oil was proven to reduce the density value to 0.81 g/mL, flow rate 4.17 mL/s, acid number 3.6 mg/KOH and saponification value 427 mg/KOH.

Abstract

The high demand for cooking oil causes scarcity and increases the price of cooking oil in the market. Despite the scarcity, people still use it by heating it repeatedly. Cooking oil that has been used repeatedly is called used cooking oil which contains saturated fatty acids which will have a negative impact on health if reused. Therefore, this study aims to clarify used cooking oil by using carbon from moringa peels to improve the quality of used cooking oil. Moringa fruit peel contains cellulose and hemicellulose so that it can be used as a carbon source using the calcination method and tested for approximation such as tests for ash content, vapor content and bound carbon. Furthermore, carbon is applied in the clarification of used cooking oil by adsorption method. After the used cooking oil has been clarified, the properties of the used cooking oil are tested, such as density, flow rate, acid number and saponification number. The result of this research is that the resulting Moringa peel carbon at 250 - 350oC complies with the SNI 06-3730-2021 standard. The application of Moringa peel carbon in used cooking oil has been shown to reduce the density value to 0.886 g/mL, an acid number of 4.476 mg/KOH, and succeeded in increasing the value of the flow rate to 0.735 and the saponification number to 351.751 mg/KOH.
