Abstract
Salah satu parameter penting dari performa suatu mesin diesel adalah specific fuel oil consumption (SFOC). Spesific fuel oil consumption memiliki definisi sebagai berapa banyak jumlah bahan bakar yang dibutuhkan untuk menghasil 1kWh energi listrik, dan normalnya bergantung pada daya aktual mesin (Lundh, 2016). Jenis dinamometer yang tersedia di pasaran di Indonesia sangat terbatas dan hanya bisa digunakan untuk mengukur torsi kendaraan bukan torsi mesin, dan dengan harga satu unit yang cukup mahal sehingga relatif belum terjangkau bagi lembaga riset yang baru berkembang. Penelitian ini dilakukan dengan dua metode, yaitu metode rekayasa dan metode eksperimen. Alat ukur ini menggunakan komponen, yaitu rem cakram dengan diameter 180mm, caliper nissin, master rem nissin, load cell 100 kg, sensor putaran mesin IR-08H. Penggabungan sensor menggunakan mikrokontroller Arduino UNO dan kemudian ditampilkan dalam display LCD 4x20 dan akan dicatat menggunakan Microsoft Excel. Terdapat beberapa indikator yang akan ditampilkan dalam display lcd dan data excel, diantaranya adalah, waktu pengujian, beban mesin, putaran mesin, torsi, daya, dan nilai sfoc. Dari data pengujian didapatkan bahwa nilai akurasi yang dimiliki load cell 100 kg sebesar 99.74%, dan nilai akurasi dari sensor putaran mesin sebesar 99.64%, dan nilai akurasi untuk keseluruhan alat sebesar 99.69%. Alat ini memiliki beberapa kelebihan, diantaranya adalah pembacaan nilai daya dan specific fuel oil consumption secara otomatis dan dapat memantau indikator pengujian pada tampilan lcd.

One of the important parameters of the performance of a diesel engine is specific fuel oil consumption (SFOC). Specific fuel oil consumption has the definition of how much fuel is needed to produce 1kWh of electrical energi, and normally depends on the actual power of the engine (Lundh, 2016). The types of dynamometers available on the market in Indonesia are very limited and can only be used to measure vehicle torque instead of engine torque, and with the price of one unit which is quite expensive so it is relatively unreachable for newly developing research institutions. This research was conducted in two methods, namely engineering methods and experimental methods. This measuring instrument uses components, namely disc brakes with a diameter of 180mm, caliper nissin, master brake nissin, 100 kg load cell, engine speed sensor IR-08H. Combining sensors using an Arduino UNO microkontroller and then displayed on a 4x20 LCD display and will be recorded using Microsoft Excel. There are several indikators that will be displayed in the LCD display and excel data, including the test time, engine load, engine speed, torque, power, and sfoc value. From the test data, it was found that the accuracy value of 100 kg load cell was 99.74%, and the accuracy of the engine speed sensor was 99.64%, and the accuracy value for the whole device was 99.69%. This tool has several advantages, including the reading of the value of power and specific fuel oil consumption automatically and can monitor the test indikators on the LCD display
