    Abstract
    Telah dilakukan pengamatan disipasi panas pada suatu sistem. Dalam penelitian ini digunakan Arduino Nano sebagai mikrokontroler kalibrator pengukur curah hujan berbasis web yang akan di teliti disipasinya melalui penerapan pompa otomatis, sensor DHT 22 sebagai pendeteksi perubahan temperatur mikrokontroler dalam keadaan standby selama 5 menit dan beroperasi selama 55 menit. Energi lisrik diperoleh dari pengukuran tegangan dan arus menggunakan multimeter dan Energi panas diperoleh dari perubahan temperatur yang terdeteksi sensor DHT 22. Hasil pembacaan sesnsor suhu ditampilkan dari mikrokontroler ke PC ke dalam aplikasi PLX-DAQ sebagai interface. Dari hasil pengamatan dan perhitungan, diperoleh data persentase disipasi energi listrik menjadi energi panas mengalami 4 tahap yaitu pada saat standby 8,9%, akhir standby sampai beroperasi 1,0%, transisi 0,2%, dan stabil ideal 0,1%-0%. Setelah 20 menit sampai selesai beroperasi menunjukkan keadaan stabil ideal. Hal ini disebabkan lepasan panas mikrokontroler dan energi yang di serap ambien sudah sama.
     
    The heat dissipation of a system has been observed. In this study, the Arduino Nano as a microcontroller of web based rainfall gauge calibrator will be analyzed through the application of an automatic pump, the DHT 22 sensor as a detector for temperature changes on the microcontroller on standby for 5 minutes and operate for 55 minutes. Electrical energy can be obtained from voltage and current measurements using a multimeter and heat energy can be obtained from temperature changes detected by the DHT 22 sensor. The temperature sensor readings are displayed from the microcontroller to the PC into the PLX-DAQ application as an interface. From the results of observations and calculations, the data obtained on the percentage of electrical energy dissipation into heat energy has 4 stages, that is on standby 8,9%, from the end of standby to operate at 1,0%, transition 0,2%, and ideal stable 0,1%-0% . After 20 minutes until finished operating shows an ideal stable state. This is due to the microcontroller heat dissipation and energy absorbed by the ambient is the same.
