Balance Of Plant (BOP) merupakan sebuah plant penunjang dalam sebuah pembangkit listrik khususnya di PLTGU. Dalam BOP terdapat beberapa plant untuk kebutuhan steam turbin diantaranya, Water Intake Plant (WIP), Desalination plant, Water Treatment Plant (WTP), dan Waste Water Treatment Plant (WWTP).Water Intake adalah salah satu bagian dari Balance of Plant (BOP). Di water intake ini terdapat proses seperti penyaringan sampah, penyuplai pendingin kondensor. Di dalam water intake terdapat main cooling water pump, screen wash pump , dan traveling screen. Pada water intake untuk proses stop pada screen wash pump dan travelling screen masih menggunakan metode manual. Untuk proses stop harus dilakukan melalui human mechine interface atau bisa melalui breaker. Dalam prosesnya operasinya terdapat beberapa kendala, yaitu sering terjadinya kelalian saat melakukan stop pada travelling screen dan screen wash pump. Oleh sebab itu perlu dilakukan modifikasi yaitu otomatisasi proses stop travelling screen dan screen wash pump mengikuti squence dari main cooling water pump. Saat main cooling water pump shutdown maka trevelling screen dan screen wash pump juga akan berhenti. Proyek akhir ini membahas tentang pengotomatisan proses stop pada travelling screen dan screen wash pump pada saat shutdown main cooling water pump dan diharapkan dapat mecegah terjadinya rugi-rugi daya.

Balance Of Plant ( BOP ) is a supporting plant in a power plant , especially in the power plant . In BOP there are several steam turbine plant for the needs of them , Water Intake Plant ( WIP ) , Desalination plant , Water Treatment Plant ( WTP ) , and the Waste Water Treatment Plant ( WWTP ) . Water Intake is is one part of the Balance of Plant ( BOP ) . There are at water intake screening process such as garbage , condenser cooling suppliers . In the play there is a water intake cooling water pump , screen wash pump , and a traveling screen . At the water intake to stop the process of screen wash pump and traveling screen is still using manual method. To stop the process should be done through a human or a machine interface could be through the breaker. In the process of operation there are some constraints , namely the frequent occurrence of negligence while performing the stop on the traveling screen and screen wash pump . Therefore it is necessary to modify that process automation stop traveling screen and screen wash pump follow squence from the main cooling water pump. When the main cooling water pump shutdown then trevelling screen and screen wash pump will also be stopped . The final project is about pengotomatisan stop on a traveling screen process and screen wash pump on shutdown of the main cooling water pump and hopefully prevents the occurrence of power loss
