Abstract

The increasing use of machines from various sectors causes the need for supporting materials for machine maintenance such as lubricants to also increase. To support sustainable development, biodegradable lubricants are needed of called biolubricant. Biolubricant is a lubricant based on vegetable oil as an alternative to petroleum in the hope that it is environmentally friendly and can develop biolubricant research. The purpose of this study was to obtain the optimum yield percentage, the characteristics of the biolubricant and to determine the kinetics of the synthesis reaction. This biolubricant was prepared by reacting jatropha oil with ethanol in a mole ratio of 1:1, 1:3 and 1:5 with the aid od a SO42-/TiO2-SiO2 catalyst with a mass of 1%, 1,5%, and 2%. The result of the study showed that the highest percentage yield was found in the mole ratio of 1:5 and 1% catalyst (BL 3), which was 83,2%with a density value of 0,95 gr/ml. The best biolubricant characteristics are getting viscosity as 40oC, namely 85 mpa.s and 100oC, namely 11 mpa.s, flash point value is 252oC, and pour point value is -11oC. in the GC-MS analysis test for biolubricant synthesis, there is a fatty acid content of Ricinoleic Acid which is reacted with ethanol to produce Ricinoleic Methyl Ester compound with the percentage of biolubricant formed 74,87%.

Additional Information:	Meningkatnya penggunaan mesin dari berbagai sektor menyebabkan kebutuhan pendukung bahan untuk perawatan mesin seperti pelumas juga meningkat. Untuk menunjang lingkungan yang mendukung pembangunan berkelanjutan, maka diperlukan pelumas biodegradable atau disebut biolubrikan. Biolubrikan merupakan pelumas berbahan dasar minyak nabati sebagai alternatif pengganti minyak bumi dengan harapan ramah lingkungan dan dapat mengembangkan penelitian mengenai biolubrikan. Tujuan penelitian ini adalah mendapatkan persen yield optimum, karakteristik dari biolubrikan dan mengetahui kinetika reaksi sintesis. Biolubrikan ini dibuat dengan cara mereaksikan minyak jarak pagar dengan etanol pada perbandingan rasio mol 1:1, 1:3 dan 1:5 berbantu katalis SO 2- /TiO2-SiO2 dengan massa 1%, 1,5% dan 2%. Hasil dari penelitian menunjukan bahwa persen yield tertinggi terdapat pada rasio mol 1:5 dan katalis 1% (BL 3) yaitu sebesar 83,2% dengan nilai densitas 0,95 gr/ml. Karakteristik biolubrikan terbaik yaitu mendapatkan viskositas pada 40°C yaitu 85 mpa.s dan 100°C yaitu 11 mpa.s, nilai flash point 252°C, dan nilai pour point -11 °C. Pada uji analisa GC-MS sintesis biolubrikan terdapat kandungan asam lemak senyawa Ricinoleic Acid yang direaksikan dengan etanol menghasilkan senyawa Ricinoleic Methyl Ester dengan persentase hasil biolubrikan yang terbentuk 74,87% Kata Kunci: Biolubrikan, Esterifikasi, Transesterifikasi, Flash Point, Viskositas
