Abstract
Dalam industri pembangkitan listrik, kepatuhan terhadap regulasi lingkungan terkait kualitas buangan air limbah sangat penting, terutama parameter ammonia. Pembangunan fasilitas Ammonia Recovery Plant (ARP) di PLTU Paiton berfungsi sebagai intermediate treatment dari Wastewater Treatment Plant (WWTP) untuk menangani air limbah dengan kandungan ammonia tinggi. Kegagalan operasional ARP dapat mempengaruhi kualitas buangan dari WWTP, yang dipantau sesuai izin pembuangan dari Kementerian Lingkungan Hidup dan Kehutanan (KLHK) RI. Dari tahun 2020 hingga 2023, terdapat 79 fault work order di sistem MAXIMO CMMS untuk memperbaiki masalah ARP, beberapa di antaranya menyebabkan ARP tidak beroperasi lebih dari 1 bulan. Penelitian ini bertujuan untuk mengidentifikasi risiko kritis kegagalan operasional ARP dan menentukan solusinya. Penelitian dimulai dengan identifikasi risiko kegagalan operasional kemudian dilanjutkan analisa menggunakan metode Risk Failure Modes and Effects Analysis (RFMEA) untuk menentukan risiko kritikal dari operasional ARP. Analisis dilanjutkan dengan Fault Tree Analysis (FTA) untuk menentukan basic event dari kegagalan tersebut. Sebanyak 34 mode kegagalan diidentifikasi, dan dari analisis RFMEA diperoleh 4 mode kegagalan kritis yaitu inaccurate pH reading, valve leaks, WWFD pipeline leaks in the Feed Pre-Adjust Systems, and acid injection failure in the Chemical Injection Systems. Kemudian dilakukan penyusunan mitigasi terhadap risiko kritikal tersebut dalam bentuk Risk Control Options (RCO) antara lain engineering control seperti pembuatan kanister untuk probe pH, subtitution control seperti penggantian bahan flexible joint, dan administrative control seperti revisi plant operating instruction serta penambahan pengaturan default inverter untuk teknisi. Hasil penilaian ulang skor risiko menunjukkan penurunan dari 12 poin menjadi 4 poin, yang menunjukkan bahwa analisis ini dapat digunakan sebagai acuan untuk menentukan prioritas perbaikan atau modifikasi pada sistem ARP untuk menjaga keberlangsungan operasional. Analisis ini juga dapat dikembangkan untuk sub-sistem lain dengan proses yang lebih komprehensif untuk membantu pendekatan pengambilan keputusan berbasis risiko dalam manajemen operasional perusahaan.

In the electricity generation industry, compliance with environmental regulations regarding wastewater discharge quality is crucial, especially concerning ammonia parameters. The construction of the Ammonia Recovery Plant (ARP) at PLTU Paiton serves as an intermediate treatment for the Wastewater Treatment Plant (WWTP) to handle wastewater with high ammonia content. Operational failures of the ARP can affect the discharge quality from the WWTP, which is monitored according to the disposal permit from the Ministry of Environment and Forestry (KLHK) of Indonesia. From 2020 to 2023, there were 79 fault work orders in the MAXIMO CMMS system to address ARP issues, some of which caused the ARP to be non-operational for more than a month. This study aims to identify critical risks of ARP operational failures and determine solutions. The research begins with identifying operational failure risks and then continues with analysis using the Risk Failure Modes and Effects Analysis (RFMEA) method to determine the critical risks of ARP operations. The analysis is followed by Fault Tree Analysis (FTA) to identify the basic events of these failures. A total of 34 failure modes were identified, and RFMEA analysis revealed 4 critical failure modes: inaccurate pH reading, valve leaks, WWFD pipeline leaks in the Feed Pre-Adjust Systems, and acid injection failure in the Chemical Injection Systems. Mitigation measures for these critical risks were then developed in the form of Risk Control Options (RCO), including engineering controls such as creating a canister for the pH probe, substitution controls such as replacing flexible joint materials, and administrative controls such as revising plant operating instructions and adding default inverter settings for technicians. The re-evaluation of the risk score shows a decrease from 12 points to 4 points, indicating that this analysis can be used as a reference for prioritizing repairs or modifications to the ARP system to maintain operational continuity. This analysis can also be extended to other sub-systems with a more comprehensive process to support risk-based decision-making in company operational management.
