Indonesia is the largest exporter of palm oil with 85 - 90% of the world's total palm oil production. The consumption of palm oil in Indonesia is increasing every year, thus the waste are also increase. Waste cooking oil contains carcinogenic substances which causes various diseases. Biodiesel is an environmentally friendly substitute fuel for diesel made from vegetable oil as raw material. Used cooking oil can be used as raw material for biodiesel production, but it needs to be purified before further processing. Chicken egg shell contains 90% of CaCO3 can be used as a biosorbent of used cooking oil. Durian skin contains 50% - 60% of cellulose also has the potential as a biosorbent. This research was conducted to investigated the effectiveness of the combination of chicken egg shell biosorbent with durian skin for the purification process of used cooking oil as a raw material of biodiesel. Biosorbent was produced by carbonization process in a furnace at a temperature of 550oC for durian skin and 9000C for chicken egg shells. The results show that the acid number of used cooking oil has met the parameters of the SNI 3741: 2013, namely 0.43 mgKOH / gr and FFA levels of 0.0024% with a yield of 62.76%. The purified cooking oil was then continued with the transesterification process to produced biodiesel. The biodiesel obtained had the cetane numbers B100 of 33.8 and B30 of 45.2.

Biodiesel is an alternative fuel which is generally produced from the transesterification process between vegetable oil and methanol, ethanol, or butanol with the help of a catalyst which aims to speed up the reaction. The raw material for making biodiesel, namely renewable vegetable oil, also sees Indonesia as a tropical country so that biodiesel can be produced on a large scale and is environmentally friendly. Vegetable oil can be classified into two, namely edible oil (food) and non edible oil (non-food). The research was conducted using non-edible vegetable oil, namely kemiri sunan oil, which was carried out using a two-stage transesterification method. This research was conducted to determine the optimization of the ratio of oil and methanol (1: 4; 1: 5; 1: 6), temperature (55⁰C, 60⁰C, 65⁰C) and reaction time (15 minutes, 30 minutes, 45 minutes) in making biodiesel from kemiri sunan oil, where the experimental results obtained the highest yield value of 82.79%. In the experiment, analysis of density, viscosity, moisture content and cetane number was also carried out. The results showed that the viscosity and cetane number obtained did not meet SNI for biodiesel.

Homogenization is the process of uniform particle size in an effort to maintain the stability of a mixture which is formed from 2 incompatible phases or so-called emulsion.Emulsion is a complex system consisting of a liquid phase which is spread over another immiscible liquid phase which is usually through mechanical shear. All emulsions are thermodynamically unstable due to contact between oil and water molecules. However, emulsions can be stabilized rapidly in the presence of emulsifying or thickening agents such as Tween 20 and Tween 80. Apart from the addition of emulsion stabilizing surfactants, the speed of stirring also has an effect in stabilizing the emulsion. This research was conducted to determine the effect of stirring speed and addition of surfactants Tween 20 and Tween 80 on the stability of soybean oil emulsion. The results of density, viscosity, stability, and microscopic tests showed that the emulsion was treated with the addition of tween 80 with a stirring speed of 30.
