Abstract

Surfactants are surface active ingredients that function to reduce the surface tension of a liquid. In general, surfactants are synthesized from petroleum and natural gas derivatives, but they can cause environmental pollution and are not renewable, so an alternative raw material is needed, namely palm oil. One type of surfactant that can be produced from palm oil is methyl ester sulfonate (MES). This study aims to obtain the optimum process conditions and the characteristics of the MES surfactant produced from palm oil methyl ester with the sulfonating agent Na2S2O5. The preparation of methyl esters was carried out in two stages of esterification and transesterification reactions using methanol as a source of alcohol with H2SO4 as an acid catalyst and NaOH as a base catalyst. Sulfonation was carried out at temperatures of 80, 90 and 100 0C, the ratio of methyl ester to Na2S2O5 was 1:0.5; 1:0.75; 1:1 and 5 hours reaction time.

Abstract

Biodiesel, which is generally defined as monoalkyl esters from plant and animal fats, is an alternative fuel that has the potential to be used as a substitute for diesel fuel because of its characteristics. Used cooking oil or used cooking oil haD the potential to be processed into biodiesel and this study aims was to produce waste cooking oil into biodiesel from the results of the pre-treatment process of used cooking oil with bagasse waste, to find out the optimum result of the oil pretreatment proces and the raw material used was used cooking oil from the Rocket Chicken Food Court restaurant. Waste from sugarcane bagasse was useful as an adsorption process for the purification of used cooking oil which was able to reduce free fatty acid levels, water content, and impurities levels for the biodiesel process. The optimum particle size of bagasse waste for used cooking oil pretreatment was 30 mesh, with the analytical data was 1.93% of free fatty acid, 0,0018 % for water content and 0,03% of firt level. The results of the Biodiesel analysis from the pre-treatment process were the viscosity was 5.7 Cst, the density was 860 kg/m3 and the acid number was 0.8 mg KOH/g oil. This result was accordance to the indonesian national standard No. 04-7182-2006.

Abstract

Refined Bleached Deodorized Palm Oil (RBDPO) is an oil produced from fresh fruit of the oil palm (Elais guineensis Jacq.) by going through an oil refinery process. RBDPO consists mostly of C16 palmitate fat of 44% which can be applied to shortening products. Shortening is a product derived from RBDPO oil, shortening is a processed product of semi-solid oil emulsions. This study aims to determine the process of making shortening, to find out the results of the analysis of shortening quality, to find out the optimum ratio for making shortening. The ratio of solid fat:RBDPO used in the manufacture of this shortening is 100:0, 80:20, 60:40, 40:60, 20:80, 0:100. Optimum results in the manufacture of shortening based on physical and chemical analysis, obtained with a ratio of 80% solid fat: 20% RBDPO with a moisture content of 0.29%, free fatty acid content of 0.54% and a peroxide value of 0.115 mek O2/kg.

Abstract

Renewable energy is energy that comes from renewable sources including geothermal, wind, bioenergy, sunlight, water flow and waterfalls as well as the movement and temperature differences of the ocean layers. One of the renewable energies that must continue to be developed is biomass energy derived from organic materials. The results of biomass conversion can be in the form of biogas, bioethanol, biodiesel, charcoal and so on. One of the alternative energies that can replace fossil energy sources is bioethanol. Raw materials that can be used as bioethanol are empty oil palm bunches and cassava. This study aims to determine whether the production of bioethanol from empty oil palm bunches and cassava produced is in accordance with Bioethanol Quality (SNI 7390-2012). This study consists of 5 processes, namely: preparation of raw materials, pretreatment of empty oil palm bunches, hydrolysis, fermentation, distillation. The final analysis results of bioethanol production with a density of 0.8896-0.911 gr/ml, brix content of 3-4%, pH level of 3-4, bioethanol yield of 15% - 30%. The optimum bioethanol yield is at 100% cassava variable with density data of 0.8896 gr/ml, brix content of 4%, pH level of 4, and yield of 30%. The results of the bioethanol quality test are not in accordance with the SNI 7390-2012 Standard.
