Abstract
Diesel engines is generally used for industrial and agricultural machines. Few people care about the engine temperature so it is forced to reach temperature of 100oC, which causes overheating of the diesel engine and has an impact on the performance itself. This also uses a hopper cooling system which is certainly not effective, because it's necessary to see that the water in the reservoir is still or not, also not equipped with an engine temperature display so it's difficult to ascertain the temperature inside. This study aims to monitor and control the temperature of cooling water. Operation of temperature control uses a telecontrol system that is connected to network (Internet of Things) so diesel temperature control can be done remotely. Monitoring of temperature and water level in the reserve tank using Web Mobile. In addition, there is a temperature sensor that is used to measure the temperature of the cooling water so that users can monitor the temperature of the diesel engine on Web Mobile. The test results obtained, the temperature sensor has an average temperature reading error of 0.031004%. Diesel engines with controlled solenoid valve cooling systems can produce ideal temperatures compared to when the solenoid valve is open (using the radiator continuously) or when the solenoid valve is Closed (without using a radiator). When the solenoid is controlled the engine temperature can be ideal because the solenoid valve opening and closing system has the lowest temperature of 56.34oC and the highest temperature of only 80.85oC.

Di jaman seperti sekarang ini, kehidupan manusia tidak terlepas dari piranti teknologi canggih baik berbentuk elektronik maupun tekologi lain
Kekurangan tandon ini adalah kurang efektif karena harus selalu mengecek apakah air masih ada atau sudah habis, jika air pendingin pada water jacket dalam block mesin sampai kehabisan mesin diesel mengalami suhu berlebih dan mengeluarkan asap pada cerobong apabila tidak ditangani secara cepat dapat menimbulkan over heating

Summary
Solenoid valve berfungsi menghentikan atau meneruskan aliran fluida,dimana pengaturannya dilakukan oleh arus listrik (kebanyakan tegangan kerja solenoid valve adalah 100 dan 200 VAC dan kebanyakan tegangan kerja pada tegangan DC adalah[12] dan 24 VDC). Solenoid valve terdiri dari sebuah kumparan yang berbentuk silinder dimana pada bagian tengahnya terdapat sebuah inti besi yang disebut dengan plunger. Apabila kumparan dialiri arus listrik maka kumparan menjadi elektromagnet sehinggga akan mengangkat/menarik plunger ke tengah kumparan dan akibatnya akan membuka katup. Apabila aliran listrik dimatikan maka medan magnet kumparan akan hilang dan plunger akan turun karena tekanan dari pegas sehingga menutup katup
