Abstrak

Sistem pendinginan pada mesin berfungsi sebagai pelindung mesin dengan cara menyerap panas. Panas mesin dihasilkan dari pembakaran bahan bakar dalam silinder. Panas tersebut merupakan suatu hal yang sengaja diciptakan untuk menghasilkan tenaga, namun jika dibiarkan akan menimbulkan panas yang berlebihan (over heating effect). Untuk mencegah over heating dan menjaga suhu kerja mesin maka digunakan radiator. Seberapa efektif radiator yang digunakan dapat diketahui menggunakan suatu alat yang dinamakan radiator tester. Karena itu Dalam penelitian ini dirancang Alat Uji Radiator (Radiator Tester) Skala Laboratorium Yang Dilengkapi Dengan Pengatur Putaran Mesin Dan Regulator Wind Blower L300 diesel. Penelitian dilakukan dengan cara pengujian di lapangan menggunakan mobil L 300 diesel dengan mencatat rpm dan kecepatan udara yang berhembus ke radiator. Adapun proses perancangan radiator tester mesin L 300 diesel skala laboratorium yaitu: pembuatan kerangka dudukan mesin, pembuatan radiator tester system pendingin mesin dengan memasang alat thermometer pada selang masuk dan keluar radiator, pembuatan alat mekanisme pengatur putaran mesin, pembuatan alat mekanisme regulator wind blower dan penginstalan alat uji radiator dengan pengatur putaran mesin dan wind blower. Hasil pengujian rpm dan kecepatan udara di lapangan di aplikasikan pada radiator tester skala laboratorium. Dari hasil pengujian yang dilakukan menunjukkan adanya peningkatan nilai efektivitas radiator tanpa hembusan udara luar dengan putaran mesin 1000 rpm dengan nilai rata-rata yaitu 0,483. Sebaliknya ada penurunan efektivitas radiator ketika diberikan hembusan udara luar 2,3 m/s dengan putaran mesin 1500 rpm yaitu 0,63. Kata kunci : Efektivitas , Radiator, Temperatur, Aliran udara (Cooling system in the engine functions as the protector of the machine by absorbing the heat. Heat engine is produced by fuel in the cylinder. The heat is deliberately created to generate energy, but it will cause excessive heat if it is left unchecked (over heating effect). In order to prevent overheating and keep the machine temperature, then it uses radiator. How effective radiator is used can be seen by using a tool called a radiator tester. Therefore, this research was Designed A Trial Radiator (Radiator Tester) Labotatory Scale Which is Completed by Round Handler’s Machine and Regulator Wind Blower on Diesel Engine L 300. This research was done by testing the car L 300 diesel in the field then noted rpm and air speed that blew into the radiator. The process of designing a radiator tester L300 diesel engine laboratory scale were making the framework platform machine, making radiator tester cooling system machine to set up a thermometer in the radiator hose in and out, making a mechanism round handlers machine, making a regulatory mechanism wind blower and installing a trial radiator with round handlers machine and wind blower. The rpm test result and air speed on the field was applied to the radiator tester laboratory scale. From the results of the tests, it showed that there was an increase in value of the effectiveness of the radiator without external airflow to engine speed 1000 rpm and the average value was 0.483. Whereas, there was a decrease on the effectiveness of the radiator when given outside air flow 2.3 m/s at 1500 rpm engine speed, which was 0.63. Keywords: Effectiveness, Radiators, Temperature, Air Flow)
