    Abstract
    Hospital as installation of medical services can not be separated from the existence of a number of pathogenic microbes. The presence of microbial pathogens may cause nosocomial infections are still scarce, but predicted quite high given the state of hospitals and public health is not so good relative. When the device is on, then power supply will provide voltage to each series block contained in the module. In this module port B is set as output 16x2 LCD. Port C to turn on the UV lamp through SSR driver circuit. The output voltage on port D as a push button. After the time is up, then the UV lamp will die together buzzer sounds and hour meter will stop record UV lamp life time.According to the data obtained for data retrieval time of 1 hour and 30 times the average experiment over 3553 seconds, 47 seconds storage, error of 1,30%, a standard deviation of 1,24 seconds. For the second measurement 3 hours and 10 times the average experiment for 10675 seconds, 125 seconds deviation, error 1,15%, standard deviation of 0,84 seconds. For the third measurement 6 hours 10 times the average time for 21315 seconds, 285 seconds deviation, error 1,31%, standard deviation of 2,88 seconds
     
    Rumah sakit sebagai instalasi pelayanan medis tidak mungkin lepas dari keberadaan sejumlah mikroba patogen.Keberadaan mikroba patogen tersebut dapat minimbulkan infeksi nosokomial.Di Indonesia data mengenai kejadian infeksi nosokomial masih langka, tetapi diperkirakan cukup tinggi mengingat keadaan rumah sakitdan kesehatan umum relativ belum begitu baik.Ketika alat on maka power supplyakan memberikan tegangan ke setiap blok rangkaian yang ada pada modul ini. Pada modul ini port B diatur sebagai keluaran LCD 16x2.Keluaran pada port C untuk menyalakan lampu UV melalui rangkaian driver SSR.Tegangan keluaran pada port D sebagai tombol pushbutton. Setelah waktu tercapai maka lampu UV akan mati secara bersama-sama buzzer bunyi dan hourmeter akan berhenti mencatat life time lampu UV.Sesuai dengan data yang di dapat untuk pengambilan data waktu 1 jam 30 kali percobaan rata-rata waktu selama 3553 detik, penyimpangan 47 detik, error 1,30%, standard deviasi 1,24 detik. Untuk pengukuran kedua 3 jam 10 kali percobaan rata-rata waktu selama 10675 detik, penyimpan 125 detik, error 1.15%, standard deviasi 0,84 detik. Untuk pengukuran ketiga 6 jam 10 kali rata-ratawaktu selama 21315 detik, penyimpangan 285 detik, error 1,31%, standarddeviasi 2,88 detik.
