Abstract

Penelitian ini merupakan studi kasus deskriptif terapan pada sistem proteksi transmisi Subsistem Kelistrikan Bintan dengan menggunakan data historis periode 2020–2025, dokumen operasi dan pemeliharaan, observasi lapangan, serta penilaian teknis personel yang memiliki kompetensi pada bidang proteksi, operasi, dan pemeliharaan transmisi. Sistem proteksi transmisi memiliki peran penting dalam menjaga kontinuitas penyaluran tenaga listrik. Kinerja ketersediaan sirkuit transmisi diukur menggunakan indikator Circuit Availability Factor (CCAF), yang dipengaruhi oleh durasi forced outage, maintenance outage, dan planned outage. Penelitian ini bertujuan mengevaluasi kondisi pemeliharaan existing dan kinerja ketersediaan sirkuit, menentukan mode kegagalan kritis beserta akar penyebabnya, serta menyusun rekomendasi strategi pemeliharaan berbasis Reliability Centered Maintenance (RCM). Failure Mode and Effects Analysis (FMEA) digunakan untuk memprioritaskan mode kegagalan berdasarkan nilai severity, occurrence, detection, dan Risk Priority Number (RPN), sedangkan Fault Tree Analysis (FTA) digunakan untuk menelusuri akar penyebab mode kegagalan prioritas. Hasil penelitian menunjukkan bahwa nilai CCAF meningkat dari 99,20% pada tahun 2020 menjadi 99,58% pada tahun 2025, sedangkan total durasi outage menurun dari 560 jam menjadi 294 jam. Mode kegagalan dengan RPN tertinggi adalah kegagalan rangkaian trip sebesar 80, diikuti kegagalan komunikasi intertrip sebesar 64, ketidaksesuaian setting proteksi sebesar 60, gangguan catu daya DC sebesar 60, dan kegagalan binary output sebesar 60. Hasil FTA menunjukkan bahwa akar penyebab dominan berkaitan dengan kontinuitas rangkaian trip, kanal komunikasi proteksi, pengelolaan setting, kondisi catu daya DC, dan perangkat keluaran relai. Berdasarkan analisis RCM, rekomendasi pemeliharaan meliputi penguatan in-service measurement, pelaksanaan failure-finding task, pengujian fungsi rangkaian trip dan intertrip, verifikasi setting, pemantauan catu daya DC, serta pengelompokan kegiatan dalam jadwal shutdown terencana. Strategi tersebut diproyeksikan menurunkan total outage dari 294 jam menjadi 249 jam dan meningkatkan CCAF dari 99,58% menjadi 99,64%. Hasil validasi rekomendasi memperoleh tingkat penerimaan sebesar 85,71%. Hasil proyeksi tersebut belum merupakan hasil implementasi aktual sehingga masih memerlukan uji coba lapangan untuk membuktikan dampaknya terhadap durasi outage dan nilai CCAF.

This study is an applied descriptive case study of the transmission protection system in the Bintan Power Subsystem using historical data from 2020 to 2025, operation and maintenance documents, field observations, and technical assessments conducted by personnel competent in transmission protection, operation, and maintenance. The transmission protection system plays an important role in maintaining the continuity of electricity delivery. Circuit availability performance is measured using the Circuit Availability Factor (CCAF), which is influenced by the duration of forced outages, maintenance outages, and planned outages. This study aims to evaluate existing maintenance practices and circuit availability performance, identify critical failure modes and their root causes, and formulate maintenance recommendations based on Reliability-Centered Maintenance (RCM). Failure Mode and Effects Analysis (FMEA) was employed to prioritize failure modes based on severity, occurrence, detection, and Risk Priority Number (RPN), while Fault Tree Analysis (FTA) was applied to identify the root causes of priority failure modes. The results indicate that the CCAF increased from 99.20% in 2020 to 99.58% in 2025, while the total outage duration decreased from 560 hours to 294 hours. The failure mode with the highest RPN was trip circuit failure, with an RPN of 80, followed by intertrip communication failure (64), protection setting discrepancies (60), DC power supply failure (60), and binary output failure (60). The FTA results indicate that the dominant root causes were associated with trip circuit continuity, protection communication channels, protection setting management, DC power supply conditions, and relay output devices. Based on the RCM analysis, the recommended maintenance actions include strengthening in-service measurements, performing failure-finding tasks, testing trip and intertrip circuit functions, verifying protection settings, monitoring DC power supplies, and grouping maintenance activities into planned shutdown schedules. The proposed strategy is projected to reduce the total outage duration from 294 hours to 249 hours and increase the CCAF from 99.58% to 99.64%. The validation results indicate an acceptance level of 85.71%. Since these results are projections rather than actual implementation outcomes, field trials are still required to verify their actual effects on outage duration and CCAF.
