Abstract
PT Geo Dipa Energi (Persero) Unit Dieng mengoperasikan PLTP berkapasitas 60 MW, di mana brine pump berperan penting dalam pengelolaan brine untuk injeksi reservoir guna menjaga keberlanjutan dan efisiensi sistem. Pada fasilitas uji pompa, terdapat pressure transmitter pada sisi discharge
pompa dan vibrasi (DE & NDE) pada motor sebagai sistem monitoring tanpa sistem proteksi otomatis tambahan, sehingga rentan terhadap risiko kerusakan akibat tekanan tinggi maupun vibrasi berlebih. Pada laporan ini perancangan sistem proteksi berbasis Siemens TIA Portal menggunakan logika ladder diagram pada PLC dan visualisasi HMI WinCC. Sistem proteksi pressure melakukan scaling input analog 0–25 bar dengan delay konfirmasi 5 detik, menghasilkan indikasi: Normal, High Pressure, dan Overpressure sedangkan pada sistem proteksi vibrasi menghitung nilai RMS velocity dari sensor 0–20 mm/s dengan delay konfirmasi 5 detik, menghasilkan indikasi : Acceptable, Satisfactory, Unsatisfactory, dan Unacceptable. Sistem yang dirancang berhasil memberikan peringatan dini yang akurat pada HMI, sehingga meningkatkan keamanan operasional, mencegah kerusakan peralatan, serta mendukung keberlanjutan operasi PLTP Dieng.

PT Geo Dipa Energi (Persero) Dieng Unit operates a 60 MW geothermal power plant (PLTP), where the brine pump plays an important role in brine management for reservoir injection to maintain the sustainability and efficiency of the system. In the pump test facility, there is a pressure transmitter on the pump discharge side and vibration sensors (DE & NDE) on the motor as a monitoring system without an additional automatic protection system, making it vulnerable to the risk of damage due to high pressure and excessive vibration. In this report, a protection system based on Siemens TIA Portal is designed using ladder diagram logic in a PLC and WinCC HMI visualization. The pressure protection system performs analog input scaling of 0–25 bar with a 5-second confirmation delay, producing the following indications: Normal, High Pressure, and Overpressure, while the vibration protection system calculates the RMS velocity value from a 0–20 mm/s sensor with a 5-second confirmation delay, producing the following indications: Acceptable, Satisfactory, Unsatisfactory, and Unacceptable. The designed system successfully provides accurate early warnings on the HMI, thereby improving operational safety, preventing equipment damage, and supporting the sustainability of PLTP Dieng operations.
