Risiko terbesar sistem penyediaan air minum adalah kegagalan menyediakan air minum yang aman bagi masyarakat. Berdasarkan laporan hasil pengujian sampel air produksi IPA X bulan Maret 2016 untuk pemeriksaan parameter wajib diketahui bahwa sampel melebihi baku mutu Permenkes RI No. 492 Tahun 2010 untuk parameter total koliform. Total koliform sebagai indikator pencemaran air oleh patogen menyebabkan air tidak aman dikonsumsi. Proses disinfeksi berperan penting dalam menyisihkan patogen. Kinerjanya dipengaruhi oleh suhu, pH, kekeruhan, dan zat organik. Salah satu cara pengendalian kualitas air produksi melalui pendekatan manajemen risiko menggunakan metode Failure Modes and Effect Analysis (FMEA). Risiko potensial harus terukur agar dapat ditentukan risiko penyebab permasalahan dan tindakan pengurangan risiko yang tepat. Penilaian risiko berdasarkan skala Risk Priority Number (RPN) dijadikan dasar penentuan prioritas tindakan perbaikan. Berdasarkan hasil analisis, risiko kegagalan terbesar yaitu penentuan dosis klor dan zat organik (level risiko tinggi); sisa klor (level risiko sedang); kekeruhan dan pH (level risiko sangat rendah). Usulan perbaikan untuk mengurangi risiko tersebut yaitu dilakukan penentuan dosis klor setiap hari, pengendalian pembentukan disinfectant by products (DBPs) akibat adanya zat organik dalam air dengan menurunkan konsentrasi zat oganik menggunakan granular activated carbon (GAC) atau teknologi aerasi, mengurangi pembentukan DBPs dengan menurunkan dosis disinfektan, menyisihkan DBPs setelah senyawa tersebut terbentuk menggunakan GAC, meningkatkan sisa klor menjadi 0,6 mg/l, melakukan pemantauan kekeruhan dan pH pada sistem pengoperasian filter.

Kebutuhan manusia terhadap air minum yang layak konsumsi semakin lama semakin berkembang sebanding dengan perkembangan penduduk yang kian lama kian meningkat. Untuk dapat memenuhi kebutuhan air minum sehari-hari, banyak industri yang membuka usaha air minum diantaranya adalah adanya depot air minum isi ulang (DAMIU). Pemilihan depot air minum isi ulang sebagai alternatif air minum menjadi risiko yang dapat membahayakan kesehatan jika kualitas depot air minum isi ulang masih diragukan. Penilitian ini menggunakan metode FMEA (Failure Mode and Effect Analysis) untuk mencari prioritas terjadinya kegagalan dalam proses pengolahan air minum isi ulang. Risiko-risiko yang didapat harus memiliki nilai agar terukur sehingga ditemukan prioritas penanganan dan dicari upaya untuk perbaikan. Penilaian tersebut dikenal dengan nilai RPN (Risk Priority Number) yaitu hasil pengalian dari tingkat keparahan (severity), frekuensi kejadian (occurrence) dan tingkat deteksi (detection). Berdasarkan hasil analisa dan identifikasi menggunakan metode FMEA diketahui bahwa kegagalan yang terjadi pada sistem UV dengan 3 prioritas tertinggi yaitu penggunaan UV dengan nilai RPN 100, waktu kontak UV dengan nilai RPN 100 dan penggantian filter awal dengan nilai RPN 64. Pada sistem UV dan ozon, 3 prioritas tertinggi yaitu waktu kontak sistem ozon, waktu kontak UV dan penggunaan UV dengan masing-masing nilai RPN yaitu 100. Sedangkan pada sistem UV, ozon dan RO (Reverse Osmosis) 3 prioritas tertinggi sama seperti dengan sistem UV dan ozon dengan nilai RPN yang berbeda yaitu lama pengoperasian dengan nilai 100, waktu kontak dan kesesuaian penggunaan UV dengan nilai 64.

Water Treatment Plant (WTP) “X” consists of intake, aerator, pre-sedimentation, coagulation, clearator, filter and reservoir. In the production of drinking water, several problems are encountered that threaten the process. These constraints affect the production target in regard to quality. Minister of Health Regulation No. 492 of 2010 about Requirements for Quality of Drinking Water stated every drinking water provider is obliged to guarantee the drinking water it produces is safe for human health, meeting the quality standards of physical, chemical and biological parameters. This study used Hazard Analysis Critical Control Point method. Hazard Analysis is an analytical method to identify the presence of hazards and risks in the supply production chain so the control management can be established. The existence of hazards in production process will cause losses in terms of economics and also customer trust. This method reviewed based on laboratory results of water quality and the existing conditions of operational in production process. The analysis and evaluation of its existing conditions using HACCP method generates information that the biggest source of risk that affects the quality of production is found in the operations of each processing unit and fluctuations of its debit. The corrective actions that can be taken to prevent the occurrence of failures in the production system are improving the performance of the water treatment units, discharge settings according to unit capacity, there must be modification of the flocculation and aeration process, also improvement of workers' insights regarding water quality in accordance with SNI 01-4852-1998.

The economic rise as much as 5.5% in East Java region in the first quarter of 2018 compared to the first quarter of 2017, was due to the main supporting factor of an increase in the number of industries. An increase in industry has the potential to cause environmental pollution, especially in water bodies as evidenced by an index of water quality conditions for East Java rivers that now stands on Class II. Currently, PT. X in East Java is working on the expansion of its company. This study aims to identify the risks of wastewater treatment of PT. X using the fishbone analysis method and determine the priority of failures that must be handled using the FMEA method.For research purposes, two types of data are used, namely secondary and primary data. Secondary data includes flow chart of wastewater treatment, wastewater quality report and standard operating procedures. Meanwhile, the primary data for the quality of wastewater treatment was obtained through sampling, which was carried out at each wastewater treatment unit as well as the results of questionnaire with direct interviews. From those two types of data, an analysis of the potential occurrence of risk arises by using a fishbone analysis diagram. The risk results obtained through fishbone analysis are then processed using the Failure Mode and Effects Analysis (FMEA) method to obtain a Risk Priority Number (RPN). Then, the results of risk analysis from fishbone analysis are assessed into a priority of failures, expressed in Risk Priority Number (RPN).Based on the analysis of research data, it was concluded that the problem that occurred in wastewater treatment was inefficient wastewater treatment. The inefficient process was caused by the WWTP design conditions that were greater than the inlet discharge. Based on the results of data processing using the FMEA method, it was found that the largest RPN value was 125

Drinking water is human essential need. However, there are so many contaminants contained in drinking water sources. One of the solutions to overcome this issue is using technology to produce clean drinking water which called mineral water. Mineral water industries come to understand that maintaining quality is the fundamental principle to increase sales. One of the mineral water industries in Indonesia is company X. Yet it does not have a thorough management and supervision method to control the product quality. The quality management and supervision method is used only on several aspects of production and after acquiring customer complaints. This emerges the need of company x to form an applicable, comprehensive, and standardized management system. To produce high-quality mineral water, company X can apply HACCP method. HACCP (Hazard Analysis Critical Control Point) is a system used for measuring risks and determine the control system that focused on prevention. There are five primary principles in HACCP method. Accordingly from this analysis, maintaining the unit performance, adding more detailed SOPs, and employee knowledge enhancement are the main focused of HACCP method in company X. Therefore, HACCP is a suitable method to monitor company X production system and increase the product quality

Kalimas River is a water body that passes through the city of Surabaya. The study was conducted on the Kalimas River (Segment of the Bridge Achievement Bridge) with a length of approximately 6 km. Based on the results of the water quality test of the Kalimas River (Prestasi Park-Petekan Bridge Segment) in 2016, it was found that there were several parameters that did not meet the class II water quality standards, namely BOD, COD, DO, TSS, and Phosphate. According to the Surabaya City Regulation2014-2034, the Kalimas River will be used as atourist spot and river transportation service center, so the river water must meet the quality standards for water recreation areas, which is Class II water quality.Due to these problems, the research on controlling water quality is very important. This study uses the Six Sigma method with DMAIC concept. Six Sigma is a continuous improvement effort to determine variations in the process, in order to improve the capability of that process in producing products and minimizing defects. As a characteristic of Six Sigma, DMAIC consists of five stages, which are define–measure–analyze–improve–control. Some parameters that will be used are BOD, COD, DO, TSS, pH, nitrogen, phosphateand total coliform. The first stage is “define”,in which the water quality of the Kalimas River will be measured in the form of BOD, COD, DO, TSS, pH, Nitrogen and Phosphate. Then the “measure” stage will be calculated as Deffect per Million Opportunities (DPMO) and sigma levels. In the “analyze” stage, the Root Cause Analysis (RCA) method is used to determine the root of the problem. “Improve” stage will determine potential solutions or action plans that can be applied. Then the “control” stage is conducted by making a plan to control the implementation of the action plan. The results of analysis at the six points show that there are several parameters that do not meet the Class II water quality standards, namely DO, BOD, COD, TSS, phosphate and total coliform. After calculating the Deffect per Million Opportunities in the“measure”stage, the value of the sigma level is 2.75. In the“analyze”stage, RCA method was used to find the root cause of the Kalimas River (Prestasi Park-Petekan Bridge Segment), and found the root cause was the inclusion of wastewater into rivers and river management systems

The processing of fecal sludge in the IPLT is an advanced processing activity because the sludge in the septic tank has not been properly disposed of into the environment. After all, it still contains high organic loads. IPLT Kota Batu is the object of research. It aims to determine the environmental impact caused by the treatment of sludge in the IPLT Kota Batu with the Life Cycle Assessment Method then provide an alternative in reducing the impact with the Analytic Hierarchy Process Method. Life Cycle Assessment is a method for analyzing the environmental impact of a product throughout the life cycle. Stages of life cycle assessment (LCA) are goals and scope, life cycle inventory, life cycle impact assessment, and interpretation data. An alternative selection is then made to reduce the environmental impact using the Analytic Hierarchy Process (AHP) Method. AHP is describing a complex problem into a result that is represented in a multi-level structure. AHP stages are input goals, criteria, alternatives, weighting, and priority scale, producing the recommended answer or decision. From the LCA method, it was found that the emission load released into the environment in the treatment of sludge was in the form of CO2 emissions, energy emissions, and potentially disappearing species fractions of 3.948,935 kg CO2/year, 1.100.334,84 MJ, and 3.624,647 PDF.m2.y. The use of this method can find out that the treatment of sludge in the IPLT Kota Batu has an environmental burden and impacts the phenomenon of global warming, non-renewable energy, and aquatic eutrophication. The best alternative to reduce emissions in the treatment process of sludge in the IPLT Kota Batu is to perform maintenance treatment on a scheduled basis.
