“…Biji kemiri sunan mengandung minyak sekitar 45-50% (Pranowo et al, 2013) dengan produktivitas pohon kemiri sunan dapat mencapai 250 kg biji/pohon/tahun (Syakir & Karmawati, 2014). Pada minyak kemiri sunan terdapat sekitar 50% asam α-eleostearat yang bersifat racun, sehingga menjadikan minyak kemiri sunan tidak dapat dikonsumsi (Nurjanah et al, 2019). Oleh karena itu pemanfaatannya sebagai bahan baku pada pembuatan biodiesel akan sangat menguntungkan.…”

Kemiri sunan oil is non-food oil. Kemiri sunan oil can be a potential raw material for biodiesel synthesis. Kemiri sunan oil has relatively high free fatty acid content so that before the transesterification stage, it is necessary to lower the levels of free fatty acids through an esterification reaction. In esterification, the moisture content in oil and fat as raw material for biodiesel affects the conversion rate of free fatty acids into biodiesel, so this needs to be studied. The purpose of this study was to study the effect of the moisture content in kemiri sunan oil on the conversion of free fatty acids into biodiesel at the esterification stage. The moisture content in kemiri sunan oil was varied through the evaporation step at 105°C for 1, 1.5 and 2 hours' time variations. Kemiri sunan oil with various moisture content was further esterified at 60°C, the mole ratio of oil to methanol was 1:6, the reaction time was 1.5 hours, and 1%(v/v) was catalyzed by 98% sulfuric acid. The results showed that the less moisture content in kemiri sunan oil, the less free fatty acid content was present in the biodiesel from the esterification results. This shows that the less moisture content in kemiri sunan oil at the esterification stage, the higher the conversion of free fatty acids to methyl esters or biodiesel. The highest conversion of free fatty acids into biodiesel of 91.89% was achieved when esterification was carried out on kemiri sunan oil with the lowest moisture content, namely 0.15%.

Commercial biodiesel of oil palm is controversial as the palm oil is classified as food oil and palm plantation utilizes fertile land. One potential type of vegetable oil as biodiesel raw material is kemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) oil. This research aimed to prepare a heterogeneous solid catalyst in the form of an impregnated SiO 2 by CaO catalyst (CaO/SiO 2 ), to study the effect of the esterification stage on free fatty acid (FFA) content of oil, and to test the activity of the CaO/SiO 2 catalyst during the trans-esterification stage for biodiesel formation. CaO/ SiO 2 catalysts were prepared by sol-gel method made from natural materials (egg shells and rice husk). The FFA content of kemiri sunan oil was determined through various esterification stages namely 1; 1.5; and 2 hours in the presence of H 2 SO 4 catalyst. While the trans-esterification stage was carried out under reaction temperature of 60 °C, oil to methanol ratio of 1:9, reaction time of 2 hours and CaO/SiO 2 catalyst content of 3%. The results showed that the esterification stage for 1; 1.5; and 2 hours reduced the FFA content from 12.5% (without esterification) to 0.65%; 0.58%; and 0.54% respectivaly. Biodiesel made from kemiri sunan oil which was synthesized with the addition of CaO/SiO 2 catalyst at optimal conditions of trans-esterification stage fulfilled SNI 7182-2015: Biodiesel based on density, viscocity, moisture content, iodine number, and cetane number.

Biodiesel is an alternative fuel substitute for fossil fuel, which is produced from the trans-esterification and esterification process of vegetable oil and animal fats. One of the potential materials to be processed to biodiesel is kemiri sunan (Reutealis trisperma), due to its high oil content and inedible amount of toxic. Study based on literature review has been done to identify and analyze the effect of catalysts to the yield of biodiesel from kemiri sunan (Reutealis trisperma) oil. The acquired data on the catalyst used on the experimental trials was categorized as KOH with concentrations of 0.2%, 0.4%, 0.5%, 0.6%, 1.0%, 1.5% and 2.0% and NaOH with concentrations of 0.5%, 0.75%, 1.0%, 1.25%, 1.5% and 2.0%. Based on the data analysis, it was found that the biodiesel that meets the Indonesia National Standard (SNI) requirements was the biodiesel treated with 0.2% KOH and processed in two stages of trans-esterification. Further experimental studies on the multi stages trans-esterification and catalyst treatments are still needed to explore the potential of kemiri sunan for biodiesel production.
