Abstract
Pembangkit Listrik Tenaga Surya (PLTS) merupakan salah satu teknologi energi terbarukan yang berperan penting dalam mendukung transisi energi berkelanjutan. Oleh karena itu, operasional PLTS harus dijaga agar tetap aman dan andal guna menjamin keberlangsungan pasokan energi serta keselamatan sistem dan personel. Penelitian ini bertujuan untuk melakukan penilaian risiko pada sistem PLTS di Renewable Energy Integration Demonstrator of Indonesia (REIDI) menggunakan metode Hazard and Operability Study (HAZOP) dengan pendekatan Fuzzy Risk Matrix serta merumuskan rekomendasi mitigasi yang mencakup faktor rekayasa dan faktor manusia. Penilaian dilakukan terhadap 5 node yaitu fotovoltaik, inverter, komunikasi, grounding, dan baterai yang meliputi 70 parameter operasional. Hasil analisis menunjukkan bahwa 3 parameter (4,29%), yaitu PPV Cluster 1, Komunikasi Inverter (COM-INV), dan Komunikasi Sensor Temperatur dan Radiasi (COM-SENS), termasuk kategori Very High dengan skor crisp 21,17. Selanjutnya, 1 parameter (1,43%), yaitu BESS-SOC, termasuk kategori Medium dengan skor crisp 8,00, 2 parameter (2,86%), yaitu PPV Cluster 3 dan Resistansi Desain Grounding (GND-R), termasuk kategori Low dengan skor crisp 4,50, dan 64 parameter (91,43%) termasuk kategori Very Low dengan skor crisp 1,72. Hasil uji korelasi Spearman menunjukkan koefisien korelasi sebesar 0,6779 dengan nilai signifikansi p < 0,05, yang menunjukkan adanya hubungan positif yang signifikan antara hasil penilaian risiko menggunakan HAZOP konvensional dan Fuzzy Risk Matrix. Berbeda dengan HAZOP konvensional yang menghasilkan risk score diskrit, pendekatan FRM menghasilkan nilai crisp yang bersifat kontinu sebagai hasil proses inferensi fuzzy dan defuzzifikasi untuk menentukan tingkat risiko (risk ranking). Berdasarkan hasil penilaian risiko, rekomendasi mitigasi yang diusulkan meliputi penyusunan program preventive maintenance, logbook pemeliharaan, dan prosedur penanganan gangguan, perbaikan atau penggantian inverter yang mengalami gangguan, evaluasi arsitektur komunikasi inverter, pemulihan sistem komunikasi antara Weather Station dan EMS Panel, serta evaluasi sistem kendali BESS yang mencakup konfigurasi Battery Management System (BMS), Energy Management System (EMS), dan logika operasi charging/discharging. Implementasi rekomendasi tersebut diharapkan dapat meningkatkan keandalan, keselamatan, dan kontinuitas operasional sistem PLTS di REIDI.

Photovoltaic (PV) power plants are one of the renewable energy technologies that play an important role in supporting the transition toward sustainable energy. Therefore, SPP operation must be maintained in a safe and reliable manner to ensure the continuity of energy supply as well as the safety of the system and personnel. This study aims to assess the risks associated with the SPP system at the Renewable Energy Integration Demonstrator of Indonesia (REIDI) using the Hazard and Operability Study (HAZOP) method with a Fuzzy Risk Matrix (FRM) approach, as well as to formulate mitigation recommendations that incorporate both engineering and human factors. The risk assessment was conducted on five nodes, namely photovoltaic, inverter, battery, communication, and grounding, comprising a total of 70 operational parameters. The results indicate that three parameters (4.29%), namely PPV Cluster 1, Inverter Communication (COM-INV), and Temperature and Irradiance Sensor Communication (COM-SENS), were classified as Very High risk with a crisp score of 21.17. Furthermore, one parameter (1.43%), BESS State of Charge (BESS-SOC), was classified as Medium risk with a crisp score of 8.00, two parameters (2.86%), namely PPV Cluster 3 and Grounding Design Resistance (GND-R), were classified as Low risk with a crisp score of 4.50, while the remaining 64 parameters (91.43%) were classified as Very Low risk with a crisp score of 1.72. The Spearman correlation test yielded a correlation coefficient of 0.6779 with a significance level of p < 0.05, indicating a significant positive relationship between the risk assessment results obtained from the conventional HAZOP method and the Fuzzy Risk Matrix. Unlike the conventional HAZOP method, which produces discrete risk scores, the FRM approach generates continuous crisp values through fuzzy inference and defuzzification processes to determine the risk ranking. Based on the risk assessment results, the proposed mitigation measures include establishing a preventive maintenance program, maintenance logbooks, and fault-handling procedures; repairing or replacing malfunctioning inverters; evaluating the inverter communication architecture; restoring communication between the Weather Station and the EMS Panel; and evaluating the Battery Energy Storage System (BESS) control system, including the configuration of the Battery Management System (BMS), Energy Management System (EMS), and the charging/discharging operating logic. The implementation of these recommendations is expected to improve the reliability, safety, and operational continuity of the Solar Power Plant at REIDI.
