Abstract

PLTU PT PJB UP Gresik merupakan salah satu pembangkit listrik tenaga uap yang berada di area Jawa dan Bali. Pada steam drum unit 4 PJB Gresik ini berfungsi untuk menghasilkan uap, maka dari itu kualitas air harus dijaga supaya uap yang dihasilkan berkualitas baik. Penerapan metode hazard and operability analysis (HAZOP) pada tugas akhir ini bertujuan untuk menganalisis bahaya yang terjadi pada steam drum unit 4 PLTU PJB Gresik serta menerapkan manajemen risiko untuk mengetahui risiko dalam menghadapi bahaya yang terjadi. Setelah dilakukan analisis, risiko bahaya tinggi terjadi pada plant steam drum. Hal ini dikarenakan hasil risk matrix pada steam drum menunjukkan risiko tinggi pada kondisi Ekstrem dengan nilai 16. Equipment pada steam drum yang memiliki nilai risiko tinggi adalah drum level bernilai 4. Penyebab drum level pada steam drum mengalami kegagalan dikarenakan kualitas air yang masuk tidak sesuai (air laut masuk), overheating sehingga terjadi perubahan temperature cukup tinggi. Karena tingkat bahaya dari steam drum dapat memicu terjadinya ledakan sehingga diterapkan emergency response plan untuk meminimalisir dampak yang terjadi. ================================================================================== PT PJB UP Gresik power plant is one of the steam power plant in the area of Java and Bali. Steam drum unit 4 PJB Gresik is serves to generate steam, and therefore the water quality must be maintained in order to produce the good quality of vapor. Application of the method hazard and operability analysis (HAZOP) in this thesis is aims to analyze the dangers that occur in the steam drum unit 4 PJB Gresik power plant and apply the risk management to find out what are the risks in the face of the dangers. After doing the analysis, the high hazard’s risk is likely to occur in the plant of steam drum. This is can occurs because the risk matrix results in the plant of steam drum is indicates the high risk in extreme conditions with a value of 16. The instruments in the plant of steam drum that has a high risk score is drum level that each of the instruments has a value of 4. Cause of drum level on steam drum failure are quality of incoming water (sea water) and overheating. Because the highest danger in the steam drum can cause a leakage and trigger an explosion, then given the emergency response plan to minimize the impacts.
