Abstract

Gemuk adalah sebuah kombinasi minyak pelumas dan agen pengental (thickener). Pengentalan memberikan sifat kaku dari gemuk lumas, sebagai pengukur resistansi terhadap deformasi oleh gaya yang bekerja. Pengental (thickener) di gemuk lumas dibuat dengan mereaksi 12-hydroxystearic acid (HSA) dan lithium hydroxide untuk menghasilkan gemuk lumas, yang memiliki resistansi tinggi terhadap air. Kebutuhan 12-HSA dinilai signifikan sebagai pengental gemuk lumas. Produk ini tidak dibuat di Indonesia, sehingga industri gemuk masih bergantung kepada produk impor. Minyak jarak adalah bahan baku untuk pembuatannya, namun sangat banyak diproduksi di Indonesia. Produksi ini diinisiasi untuk mengurangi upaya impor dari 12-HSA dan menggantikan produk impor tersebut. Berdasarkan hasil yang didapatkan, dapat disimpulkan bahwa formula produk bio-grease berbahan minyak jarak menunjukkan kinerja pelumas yang setara dengan kinerja produk dengan 12-HSA impor. Terkadang menghasilkan produk unggul dibandingkan dengan salah satu yang berbahan 12-HSA impor jika perlakuan yang sesuai ditetapkan. Kinerja pelumas akan meningkat dengan penambahan agen kompleks yang juga didapatkan dari minyak jarak. Pemanfaatan minyak jarak di kajian ini menghasilkan peningkatan Domestic Content Level (DCL) di dalam produk bio-grease sebesar lebih dari 95%.

Abstract

The objective of this study is to develop a lubricant formula for the gasoline engine that has been converted to compressed natural gas (CNG-fueled). The lubricant specification is SAE 15W40 API SL. This study was conducted in six stages, namely; i). lubricant formulation, ii). laboratory scale production, iii). Laboratory analysis, iv). pilot scale production and laboratory analysis, v). test performance through bench test or a road test, vi). final data analysis and evaluation. A laboratory test of physical and chemical properties of lubricants refers to the Indonesian National Standard (SNI), followed by road tests up to the mileage of 10,000 kilometers. The result showed that the lubricant formula obtained can work well to 10,000 kilometers.

Abstract

Friction affects the efficiency of a mechanical system. This paper discusses the influence of Tungsten Disulphide (WS2) as a friction modifier (FM). Friction and wear characteristics of base oil as a result of the addition of 0.1% and 0.5 % weight of WS2 were studied. WS2 nanoparticles were mixed with base oil using magnetic stirrer at 50oC for 60 minutes, then were homogenized in an ultrasonic homogenizer for 1 hour. Friction and wear characteristic of these mixtures were tested using four-ball and HFRR test-rig. The results show that the addition of both 0.1% and 0.5% WS2 nanoparticles increased by around 40% the anti-wear characteristic of mineral base oil group I and 12% for other groups of base oils. The increase in friction coefficients was in a range of 7.5% to 35% as a result of the addition of additives.
