- The use of cooking oil repeatedly in the processing of food can lead to health disorders, including liver and kidney damage. Waste cooking oil or used cooking oil if disposed of can lead to environmental pollution. One solution to overcome the problem is to recycle waste cooking oil into biodiesel, which can be used as an alternative fuel. Biodiesel from vegetable raw materials is very advantageous because it can be renewed. In this research, waste cooking oil is reacted with an alcohol using an alkaline catalyst. The separation process of products is done by using ultrafiltration membranes. Membrane separation with ultrafiltration products can accelerate the separation time of the biodiesel byproducts. Membrane was made by annealing method with a composition sellulose acetate 25%, 30% formamide and 45% acetone. The separation of the product using ultrafiltration membranes obtained maximum product + 1848 mL, with the composition of the raw materials is waste cooking oil is 2000 mL, 400 mL of methanol and 14 g NaOH. Results of analysis of the resulting biodiesel product is the density of 0.874 g / m, the viscosity of 3.5 cs, a refractive index of 1.477 and a pH of 7. The analysis shows that the separation of the product by the ultrafiltration membrane approach the standard UNI 10635.
