Abstract

Pemenuhan kebutuhan air bersih merupakan peran yang sangat penting bagi Instalasi Pengolahan Air Minum (IPA) X. Seiring berjalannya waktu, terjadi penurunan kualitas air baku yang berpotensi mengganggu kinerja unit pengolahan. Indikasi permasalahan tersebut terlihat dari hasil observasi awal di unit filtrasi, yaitu nilai kekeruhan setelah proses backwash lebih tinggi dibandingkan sebelumnya, sehingga menunjukkan adanya ketidakefektifan proses pengolahan. Untuk itu perlu dilakukan penilaian risiko kegagalan pada unit IPA. Dengan menggunakan metode Failure Mode and Effects Analysis (FMEA), penelitian ini bertujuan untuk mengidentifikasi sumber potensi kegagalan pada unit produksi IPA X serta menganalisis tingkat risiko kegagalannya. Penelitian ini dilakukan di IPA X dengan menggunakan data primer dan data sekunder. Parameter kualitas air yang dianalisis adalah kekeruhan, pH, TDS, amonium, mangan, besi, sisa klor, dan Escherichia coli. Proses analisis dimulai dengan melakukan studi literatur dan pengumpulan data, kemudian dilanjutkan dengan analisis diagram fishbone untuk mengidentifikasi akar permasalahan. Setelah itu, dilakukan penilaian risiko kegagalan untuk memperoleh nilai Risk Priority Number (RPN). Hasil penelitian menunjukkan bahwa potensi kegagalan tersebar pada seluruh unit pengolahan, dengan faktor dominan berasal dari faktor material dan metode. Berdasarkan analisis FMEA, nilai RPN tertinggi terdapat pada unit sedimentasi yaitu parameter waktu detensi yang tidak ideal dengan nilai RPN sebesar 480 sehingga rekomendasi perbaikan disusun melalui pendekatan hirarki pengendalian risiko, yang diprioritaskan pada administrative controls berupa pengendalian debit aliran, pengurasan lumpur sesuai jadwal, dan pemantauan parameter operasional berkala. Pengendalian ini tidak dimaksudkan sebagai tindakan korektif akibat menurunnya kualitas air produksi, melainkan upaya optimalisasi untuk mempertahankan kinerja unit sedimentasi.

The urgency of clean water demand plays a crucial role in the production performance of Water Treatment Plant (WTP) X. A progressive decline in raw water quality has the potential to disrupt treatment unit performance, as indicated by preliminary observations at the filtration unit, where turbidity levels after backwashing were higher than before, suggesting ineffective treatment. Therefore, a failure risk assessment of the WTP production units was required. Using the Failure Mode and Effect Analysis (FMEA) method, this study aims to identify potential failure sources in the production units of WTP X and to analyze their associated risk levels. The research using primary and secondary data. The water quality parameters analyzed included turbidity, pH, total dissolved solids (TDS), ammonium, manganese, iron, residual chlorine, and Escherichia coli. The analysis began with a literature review and data collection, followed by a fishbone diagram to identify root causes, and an FMEA assessment to determine the Risk Priority Number (RPN) for each failure mode. The results indicate that potential failure modes are distributed across all treatment units, with material and method factors as the dominant causes. The highest RPN of 480 was recorded at the sedimentation unit, linked to non-ideal detention time. Improvement recommendations were developed using a risk control hierarchy, prioritizing administrative controls, including flow rate regulation, scheduled sludge removal, and periodic monitoring of operational parameters. These measures are intended not as corrective actions in response to declining water quality, but as optimization efforts to sustain the sedimentation unit's operational performance.
