Synthesis of Fe and Zn Organic Fertilizer From Palm Oil Waste

Indonesia has been placed as the world's first producer of crude palm oil and crude palm oil. In producing crude palm oil (CPO) and palm kernel oil (PKO), the palm oil industry relies heavily on processing fresh fruit bunches (FFB) at palm oil mills (POM) and is traded Internationally. However, this process also produces solid organic waste [ i.e. empty bunches (EFB)], which reach up to 25 %% of FFB. The analysis shows that the application of empty bunches as organic fertilizer has not been able to increase the amount of nutrients in palm oil leaves and increase palm oil production. Application of palm oil mill effluent which is able to increase the amount of nutrients in palm oil, especially nitrogen and phosphate, and a positive impact to increase the production of oil palm plantations, especially on productivity (tons / ha).

Restructuration Fatty Acid Oil Castor Being Cocoa Butter Substitute Through Dehydration Reaction Castor Oil and This Interesterification with Coconut Oil

The purpose of this research to restructuring its acid fatty oils castor result of dehydration with coconut oil through the process interesterification to produce cocoa butter substitute (CBS). Coconut oil is obtained from coconut milk by heating it slowly over low heat. The resulting coconut oil has a FFA is 1.667%, a peroxide is 10.229 MekO2 / Kg and an iodine is 7,7080 gI2/100g, which meets the second quality standard according to SNI 01-3741-2002. The restructuring was carried out by interesterification of dehydrated castor oil with coconut oil with a ratio (50:50); (60:40); (70:30); (80:20) dan(90:10)with a NaOCH3 catalyst. The results showed that the interesterification of dehydrated castor oil with coconut oil with a ratio (50:50) was the most optimal ratio with a melting point of 33 oC which corresponds to cocoa oil (32 oC-35 oC) and contain omega-6 fats (linoleic acid).
