Abstract

The effect of giving a High Voltage to the concentration of free fatty acids in Crude Palm Oil has been observed. This research was done to use 20 KV high voltage source originating from a simple circuit FBT (Flyback Transformer) using duty cycle and the frequency used was 50% and 3 Hz respectively. In its application, this is done by passing the high voltage to two positive and negative electrodes dipped in palm oil with time variations of 0, 1, 2, and 3 hours. The test results show that the giving of high voltage variations in the duration of 0, 1, 2, and 3 hours gives a change in the content of free fatty acids in CPO oil that is equal to 5.16%, 5.42%, 3.24%, and 2.89% respectively. These results provide knowledge about a new method that can be developed for applications to reduce levels of free fatty acids contained in CPO oil for consumption needs such as vegetable oils which are healthier because they are low in free fatty acids. 1 INTRODUCTION Palm oil has been one of the results of the agricultural industry that has high economic value. This is because this oil has been successfully utilized into various products such as edible oils, soaps, cosmetics and fuels (Misra & Murthy, 2011). However, the presence of free fatty acids in palm oil is a negative value on the use of CPO itself (Cornelius J.A. & Agric., 1966) CPO oil which has a high content of free fatty acids has poor quality and provides various disadvantages so the process of reducing free fatty acid levels needs to be done (Atinafu & B Bedemo, 2011). The existing method and commonly used to reduce the content of free fatty acids is the thermal method. The thermal method that is commonly used in palm oil processing factories still has many weaknesses, including the high operational costs and the ability to reduce free fatty acid levels themselves. Thus, alternative methods for reducing free fatty acids are needed. High voltage electricity has been widely applied in various
