Malang is a city in East Java with the level of development of rapid settlement areas, the region has grown in areas of land rainwater. The consequence of this development is the emergence of some new inundation in urban areas, one of them in Subdistrict Lowokwaru. Carrying amount inundation problems that occurred during 2018 in the Subdistrict Lowokwaru 4 times. Largely due to the drainage conditions are not maintained and are filled with trash and sediment. The conditions resulted in reduced sewer capacity and are not able to drain rainwater discharge and wastewater. Evaluation of the drainage system in subdistrict Lowokwaru includes analysis of technical and economic. On the technical aspects, hydrology and hydraulic analysis are carried out and evaluates sewer capacity. Economic aspects discuss the funding costs and maintenance operations of the drainage system management, as well as discuss the analysis of feasibility studies by calculating Benefit Cost Ratio and Net Present Value. The analysis showed that there are 21 sewers in condition without sediment that capacity is insufficient and 23 sewers in conditions with sediment are not met or sewer capacity is not technically eligible. It is necessary for a handling plan as an attempt to deal with the sewer capacity to drain the runoff discharge. The evaluation of economic aspects shows that the activity of handling inundation problems in the drainage system in Subdistrict Lowokwaru is feasible. This can be seen from the value of the B / C ratio is 1.83 (greater than 1) and the NPV value is positive

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.

Sistem pematusan dengan luas total 1520 ha yang dilayani oleh Rumah Pompa Greges mempunyai 1 saluran primer yaitu saluran primer Kali Greges. Kali Greges dengan panjang 4-5 km dan lebar 12-22 meter merupakan muara dari 17 saluran sekunder. Selain rumah pompa Greges yang melayani Kali Greges, terdapat 3 rumah pompa lainnya yaitu rumah pompa Dupak Bandarejo melayani saluran sekunder Kali Dupak, rumah pompa Asem Jaya melayani saluran tersier Kali Asem Jaya, serta rumah pompa Tidar di saluran tersier Petemon Kali yang tidak dioperasikan lagi. Variabel studi yang digunakan yaitu kapasitas pompa, debit aliran ke saluran primer, dan debit aliran ke saluran sekunder. Metode yang digunakan yaitu melakukan perhitungan hidrolika untuk mengetahui debit saluran rencana dan debit eksisting. Dilakukan juga perbandingan kapasitas pompa saat ini dan kapasitas awal serta dilakukan analisis terhadap Standard Operating Procedure (SOP) pengoperasian pompa. Hasil evaluasi ini menunjukkan kondisi eksisting 5 segmen saluran sekunder yaitu Kali Tembok Gede, Kali Semarang, Kali Margo Rukun, Kali Demak Timur, dan Kali Dupak tidak mampu melayani debit limpasan air hujan yang disebabkan karena adanya sedimen. Selain itu, juga tidak adanya SOP pengoperasian pompa secara tertulis, yang menyebabkan terjadinya genangan dengan luas total genangan 5,71 ha dengan lama waktu genangan maksimum 240 menit dan tinggi genangan maksimum 40 centimeter pada tanggal 16 April 2016 yang merupakan salah satu genangan terbesar di catchment area sistem pematusan Greges.

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

IPAM Karangpilang’s water quality has fluctuated and there are several parameters whose quality is not in accordance with the quality standard. Therefore, IPAM Karangpilang II needs to carry out quality control to maintain the quality of drinking water products according to the applicable quality standards. This research aims to analyze the application of the quality control system for drinking water products at IPAM Karangpilang II and look for the causes of decreasing production water quality at IPAM Karangpilang II. So that alternative improvements can be determined to maintain drinking water quality at IPAM Karangpilang II. Quality control method in this study using Statistical Process Control (SPC). Analysis were using primary data on drinking water quality starting from March to April 2019. Measurement parameters used include pH, Total Dissolved Solid (TDS), Turbidity, and Organic matter. Determination of a process controlled using control chart and then implemented using a fishbone diagram to determine the factors that result in decreased production of water quality. Control charts are in a statistically uncontrolled condition on the pH parameters in the clearator and filter units, Total Dissolved Solid (TDS) parameters on the clearator unit, turbidity parameters in the pre-sedimentation unit, clearator and filter, and organic matter parameters in pre-sedimentation and filter units. While in the production of water control chart in a state of uncontrolled statistically in the turbidity. Based on the fishbone diagram, factors that cause the control chart to be in an uncontrolled condition are that the overflow rate clearator does not appropriate with design criteria, technical errors such as clogging of the tube settler on the clearator, congestion coagulant pump stagnation, tube settler replacement in the clearator, seldom using coagulant dosage , decrease in the quality of raw water in the parameters of organic matter and raw water conditions that fluctuate due to the rainy season
