Refrigerator has been widely used by the community and can be found in almost every shop, office building and household. The application of refrigeration machines can also be developed in many other equipment and machines, one of which is in the distillation apparatus. Distillation is a method of separating two substances. A distillation machine using a cooling machine in the condenser will be very helpful, especially for distillation. This study aims to determine the effect of cooling on the performance of the cooling machine. Cooling engine performance coefficient of achievement (COP). Load variations are carried out by adjusting the boiler temperature using a thermostat. In this study, data on the temperature and pressure of the refrigerant flowing in the refrigeration system were taken at four points, namely before entering the compressor, before entering the capillary tube and before entering the evaporator . In this study also used four variations of the cooling load given to the box cooler of 110 °C, 125 °C, 140 °C, and 155 °C. Then the temperature and pressure data is processed to get the COP value every time from all variations of the cooling load. The results showed that the increaseing in the cooling load, the smaller the COP value of the cooling machine. In its effect on the length of time the COP value of each variation of the cooling load increases. The highest COP value in this study was obtained at a cooling load temperature of 110 ºC of 10.69 and the lowest was obtained at a temperature of 155 ºC of 9.38.

“…Green diesel mempunyai jumlah atom karbon C15 -C18 yang memiliki titik didih 250⁰C -400⁰C [1]. Apabila ditinjau dari kebutuhan mesin dan kebutuhan proses, temperatur distilasi yang optimal pada green diesel adalah 260⁰C -330⁰C [4]. Salah satu faktor yang mempengaruhi proses distilasi adalah adanya refluks.…”

Green Diesel merupakan salah satu sumber energi alternatif yang dapat diperbaharui dan mampu mengurangi ketergantungan energi nasional terhadap energi fosil. Hal ini dikarenakan green diesel dapat diproduksi dari minyak nabati dan limbah seperti minyak jelantah dengan proses hidrogenasi trigliserida menggunakan reaktor hydrotreating. Secara karakteristik minyak jelantah dapat digunakan sebagai bahan baku pembuatan green diesel karena mengandung trigliserida dan asam lemak bebas. Namun dari hasil green diesel yang diproduksi masih banyak mengandung fraksi selain diesel, sehingga masih perlu dilakukan proses pemisahan. Proses pemisahan yang dilakukan yaitu dengan menggunakan kolom distilasi bubble cap tray. Pada penelitian ini dilakukan 2 kali percobaan yaitu distilasi menggunakan refluks dan distilasi tanpa refluks dengan variasi masing-masing jumlah tray (1,2,3, dan 4 tray) menggunakan 1500 ml crude green diesel dengan temperatur boiler 260 , temperatur kondensor dan refluks 10 . Waktu operasi yang digunakan 90 menit pada tiap variasi. Dari hasil penelitian, diperoleh kondisi optimum proses distilasi green diesel yaitu distilasi dengan refluks pada tray 1. Adapun hasil analisa karakteristik distilat berupa green diesel yaitu densitas sebesar 0,815 – 0,830 gr/cm3, viskositas kinematik sebesar sebesar 2,70 – 2,72 mm2/s, titik nyala sebesar 55 – 57,8oC, nilai kalor sebesar 44,95 MJ/kg atau 10736,4051 Cal/gr, dan cetane number sebesar 100,7 CN. Dari hasil analisa tersebut produk green diesel yang dihasilkan telah memenuhi standar Green Diesel European Standards EN15940:2016/A1:2018.

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.
