Pemanfaatan Karbon Aktif Kulit Buah Kelor (Moringa oleifera) dan Tepung Tapioka sebagai Adsorben Penjernihan Minyak Jelantah

Abstract

The waste cooking oil is waste frying oil that is no longer suitable for consumption. However, in conditions of scarce oil and rising prices, some people still consume waste cooking oil. So that waste cooking oil is safe to consume, in this study purification of waste cooking oil was carried out by adding activated carbon from the mixture of Moringa fruit peel and tapioca flour. Moringa fruit peel was carbonized at 250⁰C for 60 minutes. The resulting carbon is activated with NaOH. The purification process is carried out by mixing activated carbon and tapioca flour into waste cooking oil. The results show that using activated carbon separately from flour can improve the physical properties of waste cooking oil. These results were obtained from density and flow rate tests. However, the acid and saponification numbers do not change. Different results were obtained when carbon was mixed with tapioca flour. The density and flow rate of the oil is no different from the oil before it is mixed with flour and carbon. However, the oil looks clearer and cleaner, visually.
