ABSTRAKBunker merupakan suatu ruang bawah tanah tempat seismometer dioperasikan. Suhu, kelembaban udara serta arus dan tegangan salah satu faktor yang dapat mempengaruhi kinerja seismometer. Monitoring dan kontrol terhadap faktor-faktor tersebut dapat mengurangi resiko kerusakan serta memperpanjang life time dari seismometer. Metodologi penelitian dilakukan dengan melakukan pengukuran terhadap suhu dan kelembaban menggunakan sensor SHT11 dengan kontrol ruang bunker menggunakan kipas DC. Pengukuran arus dan tegangan menggunakan sensor ACS712. Sensor tegangan yang dikontrol berdasarkan waktu pada Real Time Clock. Pengolahan hasil pengukuran menggunakan ATMega 2560 dan ditampilkan pada LCD. Monitoring terhadap keseluruhan sistem menggunakan komunikasi SMS. Pengujian sistem dilakukan dalam ruang bunker seismometer Sekolah Tinggi Meteorologi Klimatologi Dan Geofisika. Hasil penelitian menunjukan bahwa sistem yang dirancang dapat bekerja dengan baik.Kata kunci: bunker seimometer, sensor SHT11, sensor acs712, SMS. ABSTRACTBunker is a basement room where seismometers operated. Temperature, humidity as well as current and voltage of among the factors that can affect the performance seismometers. Monitoring and control of these factors can reduce the risk of damage and extend the life time of a seismometer. The Method of this research was conducted by measuring the temperature and humidity using SHT11 sensor to the control room using a fan DC bunker. Current and voltage measurements using sensors ACS712. Sensor voltage is controlled based on the Real Time Clock time. Processing of measurement results using ATMega 2560 and displayed on the LCD. Monitoring the whole system using SMS communication. Tests performed in a bunker system seismometers School of Meteorology Climatology and Geophysics. The results of research showed that the designed system can work properly.
