Abstract
Laporan ini menyajikan evaluasi komprehensif terhadap proses operasional dan upaya penanganan masalah di Pembangkit Listrik Tenaga Uap (PLTU) PT Cirebon Power Services, yang mengoperasikan boiler dengan teknologi supercritical berkapasitas 1x660 MW. Kegiatan magang difokuskan pada pemahaman proses utama yang meliputi Hypochlorination Plant, Water Treatment Plant, dan Main Plant. Secara spesifik, studi pemecahan masalah diarahkan pada penanganan pembentukan kerak (scaling) dalam sistem perpipaan akibat tingginya padatan terlarut dalam air laut sebagai bahan baku utama. Akumulasi endapan kalsium karbonat dan kalsium sulfat berpotensi menghambat aliran serta menurunkan efisiensi termal. Oleh karena itu, dilakukan studi komparasi mengenai kecenderungan pembentukan kerak sebelum dan sesudah pengaplikasian injeksi agen antiscalant pada kondisi normal dosing. Metodologi penyelesaian masalah ini mengintegrasikan prediksi kecenderungan scaling menggunakan metode Stiff and Davis Stability Index (S&DSI) serta optimasi kinerja antiscalant melalui simulasi perangkat lunak Winflows Design Simulator versi 4.06. Evaluasi kelayakan sistem juga divalidasi melalui perhitungan neraca massa dan neraca energi pada unit-unit pembangkit, yang mencakup turbin tekanan tinggi, turbin tekanan menengah, turbin tekanan rendah, serta kondensor. Hasil analisis indeks saturasi dan simulasi tersebut selanjutnya memberikan proyeksi komparatif yang sangat krusial sebagai landasan penentuan strategi mitigasi. Penerapan dosis antiscalant yang paling optimal diharapkan mampu mencegah presipitasi mineral secara menyeluruh, sehingga keandalan fasilitas perpipaan tetap terjamin dan operasi produksi listrik dapat berjalan pada tingkat efisiensi maksimum.

This report presents a comprehensive evaluation of the operational processes and troubleshooting efforts at the PT Cirebon Power Services Steam Power Plant, which operates a supercritical boiler with a capacity of 1x660 MW. The internship focused on understanding the main processes, including the Hypochlorination Plant, Water Treatment Plant, and Main Plant. Specifically, the problem-solving study addressed scaling in the piping system caused by high levels of dissolved solids in seawater, which serves as the primary feedwater source. The accumulation of calcium carbonate and calcium sulfate deposits has the potential to obstruct flow and reduce thermal efficiency. Therefore, a comparative study was conducted on scaling trends before and after the application of antiscalant injection under normal dosing conditions. The problem-solving methodology integrated scaling trend predictions using the Stiff and Davis Stability Index (S&DSI) method and antiscalant performance optimization through simulation using Winflows Design Simulator software version 4.06. The system’s feasibility was also validated through mass and energy balance calculations for the power plant units, including the high-pressure turbine, intermediate-pressure turbine, low-pressure turbine, and condenser. The results of the saturation index analysis and these simulations subsequently provided critical comparative projections that serve as the foundation for determining mitigation strategies. The use of the optimal antiscalant dosage is expected to completely prevent mineral precipitation, thereby ensuring the reliability of the piping system and allowing electricity production to operate at maximum efficiency.
