Abstract

Air minum yang layak konsumsi memerlukan proses disinfeksi untuk mencegah kontaminasi mikrobiologis. Salah satu metode disinfeksi yang paling banyak digunakan di Indonesia adalah klorinasi karena efektif dalam membunuh mikroorganisme patogen. Proses klorinasi dilakukan dengan penambahan klorin dalam konsentrasi tertentu sehingga menyisakan sisa klor pada jaringan distribusi sebagai indikator keberhasilan disinfeksi. Berdasarkan penelitian yang sudah dilakukan pada Perumda Tugu Tirta Kota Malang di tahun 2018, dari 249 District Meter Area (DMA) yang diuji, hanya 126 DMA yang memenuhi syarat siap minum. Sebanyak 85 DMA tergolong kurang siap minum dan 38 DMA tidak siap diminum secara langsung. Salah satu DMA yang belum memenuhi syarat tersebut adalah DMA Supit Urang I.
Penelitian ini dirancang untuk menganalisis proses klorinasi yang dilakukan, penyebaran sisa klor, dan merencanakan dosis klor pada jaringan distribusi Zona Supit Urang I Perumda Tugu Tirta. Data primer diperoleh melalui pengambilan sampel di kran pelanggan pada jaringan distribusi. Parameter yang diukur meliputi kadar sisa klor menggunakan Free Chlorin Checker, suhu menggunakan termometer digital, serta pH menggunakan pH meter portabel. Data sekunder meliputi debit pemakaian air harian, proses klorinasi yang dilakukan, dan data jaringan distribusi. Analisis dilakukan dengan memanfaatkan perangkat lunak EPANET 2.2 untuk memodelkan pola sebaran sisa klor berdasarkan data lapangan dan data sekunder, dengan validasi menggunakan metode Root Mean Square Error (RMSE).
Proses klorinasinya dilakukan dengan cara menginjeksikan gas klor langsung ke dalam reservoir dengan dosis gas klor sebanyak 0,065 kg/jam. Pola penyebaran konsentrasi sisa klor menunjukkan penyebaran sisa klor belum merata dan masih belum memenuhi baku mutu yang ditetapkan oleh Peraturan Menteri Kesehatan Nomor 2 Tahun 2023. Dimana pada titik terdekat pelanggan didapatkan nilai sisa klor sebesar 0,69 mg/L dan pada titik terjauh sebesar 0,57 mg/L. Upaya yang dilakukan untuk menurunkan konsentrasi sisa klor dengan cara penyesuaian penurunan dosis klor menjadi 0,057 kg/jam pada reservoir Zona Supit Urang I.

Drinking water that is safe for consumption requires a disinfection process to prevent microbiological contamination. One of the most widely used disinfection methods in Indonesia is chlorination because it is effective in killing pathogenic microorganisms. The chlorination process involves adding chlorine at a certain concentration, leaving a residual chlorine in the distribution network as an indicator of successful disinfection. Based on research conducted by Perumda Tugu Tirta in Malang City in 2018, out of 249 District Meter Areas (DMA) tested, only 126 DMA met the criteria for being ready to drink. A total of 85 DMA were classified as less ready to drink, and 38 DMAs were not ready to be consumed directly. One of the DMAs that did not meet the requirements was DMA Supit Urang I.
This study was designed to analyze the chlorination process, the distribution of residual chlorine, and to plan the chlorine dosage in the distribution network of Zone Supit Urang I at Perumda Tugu Tirta. Primary data were obtained by sampling at customer taps within the distribution network. The measured parameters included residual chlorine levels using a Free Chlorine Checker, temperature using a digital thermometer, and pH using a portable pH meter. Secondary data included daily water consumption, the chlorination process carried out, and distribution network data. The analysis was conducted using EPANET 2.2 software to model the pattern of residual chlorine distribution based on field and secondary data, with validation using the Root Mean Square Error (RMSE) method.
The chlorination process is carried out by injecting chlorine gas directly into the reservoir with a chlorine gas dose of 0,065 kg/hour. The distribution pattern of residual chlorine concentration shows that the distribution of residual chlorine is not evenly distributed and still does not meet the quality standards set by the Minister of Health Regulation Number 2 of 2023, which is in the range of 0,20-0,50 mg/L. Where at the point closest to the customer, the residual chlorine value was found to be 0,69 mg/L and at the furthest point it was 0,57 mg/L. Efforts were made to reduce the residual chlorine concentration by adjusting the chlorine dose reduction to 0,057 kg/hour in the Supit Urang I Zone reservoir.
