Abstract

Oil is a basic necessity in every county, palm oil is an oil that is in high demand so the palm oil industry has an impact on world deforestation. One raw material that can be substituted is sunflower seeds, with a high antioxidant content obtained from vitamin E and selenium, amount 41.08 mg/100 gr. So we eill get a sunflower seeds oil product that is rich in antioxidants, which is beneficial for health. Extraction of sunflower seed oil was carried out using the Microwave Assisted Extraction (MAE) extraction method with N-Hexane solvent. This study will use the factorial design level 23 method to determine the most influential process variables to produce optimum operating conditions in making sunflower seed oil with Quicker Method analysis where the changing process. The variables extraction are temperature (T), time (W), and solvent volume (V), and the most influential process variables were obtained, amount extraction time of 9 minutes, temperature of 60°C, and solvent volume of 500 mL producing an oil yield of 53.6%, viscosity of 53.76 cSt, density of 0.919 g/cm3, water content of 0.23% b /b, FFA of 0.32% w/w, and IC50 value of 87.613 is classified as a strong antioxidant.

Abstract

This study aims to determine the effect of water content on free fatty acid levels in nyamplung (Calophyllum inophyllum L.) seed oil. Nyamplung fruit seeds have a relatively high oil content ranging from 40%-73%, which can be used as a biodiesel raw material. Nyamplung seed oil has a high FFA content that ranges from 15%-30%. The process of extracting nyamplung seed oil is done by the soxhletation method because it is considered the most efficient and uses nhexane solvent, which has non-polar properties and can increase oil yield (more than 50%). This study will use the factorial design level 2 method to determine the most influential process variables to produce optimum operating conditions in making nyamplung seed oil with the lowest FFA content. The variables used in this study are moisture content (8% and 12%), particle size (15 mesh and 25 mesh), and the ratio of materials and solvents (1:1 and 1:3). The analysis results showed that water content had the most significant influence on free fatty acid content with a value of 0.25 and the lowest free fat content of 13.30%.
