Abstract

Pengolahan Air Minum (IPAM) merupakan instalasi yang berperan dalam memenuhi kebutuhan air bersih dengan memanfaatkan air baku untuk pengolahan air bersih sehingga dalam produksi dilakukan secara terus-menerus. Dalam pendistribusiannya, kualitas air produksi yang didistribusikan perlu memerhatikan nilai kualitas dari pasokan air yang diperoleh sebagai upaya menjaga dan mempertahankan kepercayaan konsumen. Peralatan sistem produksi yang digunakan harus prima serta mendapat perawatan dan pemeliharaan secara berkala. Selain itu, proses penambahan bahan kimia dan proses disinfeksi harus dilakukan secara efisien. Penelitian dilakukan menggunakan metode Fault Tree Analysis untuk memberikan representasi grafis tentang kegagalan peralatan, kesalahan manusia, dan faktor eksternal berperan dalam menyebabkan kejadian kerusakan. Terdapat dua tahapan analisis yaitu tahap analisis kualitatif dan tahap analisis kuantitatif. Pada tahap analisis kualitatif didapatkan faktor risiko dari penurunan sistem produksi IPAM X berupa faktor risiko air baku, pembubuhan bahan kimia, proses pengolahan dan sistem produksi. Sedangkan pada tahap analisis kuantitatif dilakukan dengan melakukan perhitungan consequence dan likelihood yang menunjukkan terdapat risiko pada penurunan kualitas air sistem produksi IPAM X. Hasil menunjukkan kualitas air produksi yang diolah oleh IPAM X pada parameter kekeruhan, total coliform dan pH telah memenuhi standar ketentuan PERMENKES No. 2 Tahun 2023 kecuali pada parameter TDS dan sisa klor. Kategori risiko pada kajian ini yaitu severe pada sub faktor disinfeksi dan unit sedimentasi. High pada sub faktor bahan kimia dan kualitas air baku, dosis pembubuhan, prasedimentasi. Major pada sub faktor injector. Significant pada sub faktor sistem backwash. Moderate pada sub faktor blower. Trivial dengan sub faktor kuantitas dan filter. Mitigasi sebaga upaya minimasi risiko dilakukan dengan kategori severe pada sub faktor disinfeksi dan sedimentasi yaitu melakukan evaluasi proses disinfeksi, pelatihan dan pembaruan SOP, monitoring ketat, perbaikan sistem disinfeksi, melakukan audit internal dan eksternal serta komunikasi dengan otoritas. Pada sedimetasi dengan meningkatan ukuran atau konfigurasi unit sedimentasi, mengatur dan mengecek debit menggunakan alat flow meter secara berkala pada inlet bak, perbaikan komponen yang aus

Drinking Water Treatment Plant (IPAM) is an installation that plays a role in meeting clean water needs by utilizing raw water for processing so that production is carried out continuously. In its distribution, the quality of the distributed production water needs to pay attention to the quality value of the water supply obtained as an effort to maintain and maintain consumer confidence. The production system equipment used must be excellent and receive regular care and maintenance. In addition, the process of adding chemicals and the disinfection process must be carried out efficiently. The research was conducted using the Fault Tree Analysis method to provide a graphical representation of equipment failure, human error, and external factors playing a role in causing damage events. There are two stages of analysis, namely the qualitative analysis stage and the quantitative analysis stage. At the qualitative analysis stage, the risk factors for the decline in the IPAM X production system were obtained in the form of raw water risk factors, chemical affixation, processing and production systems. Meanwhile, the quantitative analysis stage is carried out by calculating the consequence and likelihood which shows that there is a risk of a decrease in the water quality of the IPAM X production system. The results show that the quality of production water treated by IPAM X in the parameters of turbidity, total coliform and pH has met the standard provisions of PERMENKES No. 2 of 2023 except for the parameters of TDS and residual chlorine. The risk category in this study is severe in the disinfection sub-factor and sedimentation unit. High in the sub-factors of chemicals and raw water quality, dosage, pre-sedimentation. Major in the injector sub-factor. Significant in the backwash system sub-factor. Moderate on the blower sub-factor. Trivial with quantity and filter sub factors. Mitigation as a risk minimization effort is carried out with a severe categories on the disinfection and sedimentation sub-factors, namely evaluating the disinfection process, training and updating SOPs, strict monitoring, improving the disinfection system, conducting internal and external audits and communicating with the authorities. In sedimentation, increase the size or configuration of the sedimentation unit, adjust and check the discharge using a flow meter tool periodically at the inlet of the basin, repair worn components
