Abstract

sistem safety level air pada mini plant horizontal separator 3 fasa pada workshop instrumentasi, dimana terdapat separator yang dikendalikan ketinggiannya agar tidak terjadi pengurangan tekanan. Sensor yang digunakan dalam sistem safety level ini adalah sensor photodioda. Untuk memudahkan proses safety ini, digunakannya microcontroller ATMega 8535. Dengan adanya safety otomatis ini apabila level air pada dengan set point highhigh yang terukur photodioda tidak menerima cahaya atau cahaya yang akan masuk terhalang, maka photodioda mengeluarkan nilai tegangan rata-rata ± 4,647 V dengan ADC 237 akan menyalakan alarm dan membuka selenoid valve. Nilai tegangan yang keluar dari photodioda Dari pengujian sensor untuk keadaan set point Low-Low photodioda tidak menerima cahaya atau cahaya yang akan masuk terhalang, maka photodioda mengeluarkan nilai tegangan rata-rata ± 4,196 V dengan ADC 205, akan menutup selenoid valve, agar level water tetap terjaga. Dari data yang diperoleh didapatkan penggolongan safety berdasarkan safety integrity level (SIL) yaitu SIL 1 ============================================================================================= Safety water level system in the horizontal separator plant mini microcontroller-based 3 phase in instrumentation workshop, where there is a separator which is controlled height in order to avoid a reduction in pressure. The sensors used in the system's safety level is photodiode sensor. To facilitate this process safety, the use of microcontroller ATMega 8535. With this automatic safety when the water level in the high-high set point measurable photodiode do not receive light or the light will enter obstructed, then the photodiode issued an average voltage value ± 4,647V with ADC 237 will turn on the alarm and open the solenoid valve. Rated voltage is out of the photodiode From the test sensor to the circumstances set point Low-Low photodiode do not receive light or the light will enter obstructed, then the photodiode issuing value of the average voltage ± 4.196 V with ADC 205, will close the solenoid valve so that the water level is maintained. From the data obtained safety classification obtained by the safety integrity level ( SIL ) is SIL 1
