Abstract
Kebutuhan air minum meningkat seiring dengan pertambahan jumlah penduduk. Depot air minum isi ulang saat ini hadir di kalangan masyarakat untuk memenuhi kebutuhan air minum. Harga yang ditawarkan lebih murah daripada air minum dalam kemasan, namun kualitasnya tidak sebaik air minum dalam kemasan. Hal ini dapat membahayakan kesehatan masyarakat yang mengkonsumsinya jika dalam air minum isi ulang tersebut terdapat bakteri coliform. Keberadaan bakteri coliform mengindikasikan adanya bakteri patogen lain dalam air. Pada tahun 2020 masih ditemui 7 dari 9 depot air minum isi ulang di Kecamatan Genteng kualitas produknya belum memenuhi baku mutu kualitas air minum untuk parameter mikrobiologi. Risiko tidak memenuhi baku mutu ini dapat muncul karena kegagalan selama proses produksi di depot air minum, meliputi aspek teknis dan non teknis. Tujuan dari penelitian ini adalah mengetahui sumber penyebab kegagalan kualitas air minum pada depot air minum serta menentukan tindakan perbaikan peningkatan kualitas produksi air minum yang efektif.
Identifikasi dan analisis risiko kegagalan terhadap kualitas produksi air minum isi ulang dilakukan dengan metode Failure Mode and Effect Analysis (FMEA). Metode ini merupakan salah satu metode manajemen risiko untuk mengidentifikasi kegagalan potensial dalam suatu proses produksinya yang dapat digunakan untuk membantu menentukan tindakan perbaikan guna mengurangi atau menghilangkan kegagalan selama proses produksi. Identifikasi akar penyebab kegagalan dilakukan dengan cara mencari korelasi antara hasil kuesioner mengenai kondisi lingkungan dengan nilai total coliform air produksi. Selanjutnya nilai yang signifikan dari uji korelasi disusun menggunakan diagram fishbone sebagai akar penyebab kegagalan. Setelah itu setiap akar penyebab kegagalan dilakukan penilaian berdasarkan severity (tingkat keparahan), occurrence (tingkat frekuensi terjadinya kegagalan), dan detection (tingkat deteksi kegagalan. Kemudian untuk mengetahui risiko terbesar dilakukan perhitungan Risk Priority Number (RPN) yang merupakan hasil perkalian dari ketiga penilaian sebelumnya.
Sumber kegagalan terbesar sebagai prioritas perbaikan pada DAMIU berturut-turut berdasarkan nilai RPN adalah waktu kontak lampu UV terhadap air saat pengolahan (75), backwash filter awal (48), dan pemahaman operator tentang unit pengolahan dan cara perawatan (36). Usulan perbaikan yang diberikan ialah menyalakan lampu UV selama jam operasi DAMIU, melakukan pencucian filter awal setiap satu bulan sekali, mengikutkan operator DAMIU pada pelatihan Higiene Sanitasi DAMIU yang diadakan oleh Dinas Kesehatan untuk meningkatkan pengetahuan operator DAMIU.

The need for drinking water increases with the increase in population. Refill drinking refill stations are currently available in the community to meet drinking water needs. The price of this water is cheaper compared to the bottled water; however, the quality is poor. This can endanger the health of the people who consume this water if coliform bacteria are found in this. The presence of coliform bacteria indicates the presence of other pathogenic bacteria in the water. In 2020, there are 7 out of 9 refill drinking water refill stations in Genteng District that did not meet the drinking water quality standards for microbiological parameters. The risk of not meeting the standards is due to failures during the production process at the drinking water refill stations, including technical and non-technical aspects. The purpose of this study is to determine the cause of the failure the production processes of drinking water at drinking water refill stations and to determine effective corrective actions to improve the quality of drinking water production.
Identification and analysis of failure risk on the quality of refill drinking water production are conducted using the Failure Mode and Effect Analysis (FMEA) method. This method is one of the risk management methods to identify potential failures in a production process that can be used to help determining corrective actions in order to reduce or eliminate failures during the production processes. Identification of the main cause of failure was carried out to find out a correlation between the results of the questionnaire regarding environmental conditions and the value of total coliform of produced water.
Then, the significant value of the correlation analysis is compiled using a fishbone diagram as main cause of failure. After that, each main cause of failure is assessed based on severity (severity), occurrence (frequency of failure occurs), and detection (failure detection level). After that, in order to find out the biggest risk, the Risk Priority Number (RPN) is calculated as a result of the multiplication of the three previous assessments.
The biggest sources of failure as priority for DAMIU improvement based on the RPN value are the contact time of the UV lamp to the water during processing (75), the initial backwash filter (48), and the understanding of the operator to the treatment unit and treatment methods (36). The suggestions for improvement are to turn on the UV lamp during DAMIU's operating hours, wash the initial filter once a month, and the operator must participate in the DAMIU Sanitation Hygiene training held by the Health Office to enhance the knowledge of DAMIU operator.
