ENGLISHApart from supporting irrigation systems, The Sani River has become a source of raw water for a water treatment company called PDAM Tirta Bening to provide clean water to the community. The purpose of this study was to investigate the water quality of the Sani River and formulate priority strategies for improving water quality according to the conditions of the Sani River. This research uses the descriptive-analytic method. Data were obtained from the document of Pati Regency Environmental Service, interviews, field observations, and questionnaires. To determine water quality, this study compared the test result with the water quality standards. Meanwhile, Analytic Hierarchy Process (AHP) became a tool to formulate strategic priorities. The result was TSS in the downstream, BOD, COD, and total phosphate from upstream to downstream, fecal coliform in the middle and downstream, and total coliform in the downstream conditions have exceeded water quality standard. The concentration of Dissolved Oxygen from upstream to downstream was <4 mg/L so it did not comply with the standard. The alternative strategies to improve included increasing community participation, increasing collaboration among stakeholders, supervision and law enforcement, environmental quality monitoring, and river normalization. INDONESIASungai Sani berfungsi dalam irigasi dan sumber air baku untuk PDAM Tirta Bening.

 Abstract. Banjir Kanal Barat is a river in the Garang watershed, Semarang City, Central Java, Indonesia. Its function is as a source of water for the community. The level of pollution in this river is already high. The purpose of this study is to provide advice to governments, communities and related stakeholders to realize integrated river management, and fisheries-based food security is achieved. This research method is: analyzing the water quality of the Banjir Kanal Barat river, and analyzing the amount of faecal and total coliform bacteria content in the Banjir Kanal Barat river, and analyzing how to overcome the decline in the quality of waters of the Banjir Kanal Barat river due to faecal and total coliform bacteria pollution. The results showed that the water quality at the research location was still in the quality standard. The content of coliform dan faecal bacteria at the study site exceeds the quality standard, this is due to the influence of domestic waste from households. The thing that needs to be done is counseling the existence of a clean and healthy life, especially for people who are still throwing domestic waste into the river. The existence of water purification equipment is also very necessary to overcome this problem. Water quality management can be done with policy analysis. Regulations related to water quality management can be analyzed and then given solutions and recommendations related to these rules so that policies can be taken that are sustainable, integrated, and coordinated between various parties in managing river water quality and food security. Keywords: food security, water quality, river, faecal coliform, total coliform

Abstract Ecosystem services provided by river ecosystems rely on healthy ecosystem structure and ecological processes. The Beijing-Tianjin-Hebei urban is a typical water-deficient area. As an important part of the urban-rural integration construction, evaluating the health status of the Beiyun River Basin and discovering the weak links in the water environment is the basis for improving the health of the basin. In this study, Analytic Hierarchy Process was used to establish an evaluation index system for the Beiyun River Basin from 5 aspects including water quality, biology, habitat, hydrology, and social functions, and to assign weights to the index layer. The evaluation results showed that the health evaluation results of the Beiyun River Basin in 2019 are “sub-healthy”, and the overall health status is gradually worsening from northwest to southeast. In the middle reaches of the region, the evaluation result is "healthy", followed by the upstream, and the downstream is the worst. The results showed that areas with less human interference are in better health. The factors that affect the overall health evaluation status in the basin are the level of nutrition, biodiversity, and vegetation coverage. For the comprehensive management of the Beiyun River, the improvement of water quality and habitat ecological restoration is the key to the health of the upstream ecosystem health status. The improvement of the health status of the downstream should focus on equal emphasis on water quality and quantity, restoration of biodiversity, and improvement of the quality of the riparian ecological environment.

Many companies recently have been choosing information technology (IT) outsourcing in response to complicated information systems and various internal requirements. In order to monitor and maintain a high quality of IT outsourcing vendors’ services, it is necessary to develop a system to evaluate IT outsourcing customer satisfaction. The system can be used as a tool for choosing IT outsourcing providers. Through the literature reviews and expert interviews, we propose the evaluation system of the IT outsourcing customer satisfaction. Using AHP (analytic hierarchy process) technique, attributes associated with customer satisfaction in IT outsourcing environments are then rated in terms of their importance. The customer satisfaction evaluation system is applied to IT outsourcing service receivers in Korea to demonstrate its practical implications.

Information attacks are a constant threat to every organization. To protect their sensitive information, organizations implement general information technology controls. An example of such controls includes system change controls (or change management controls), which are critical in ensuring the integrity, completeness, and reliability of financial information. The literature points to various evaluation methods of these controls to determine which ones to implement. The literature further shows how traditional assessment methods do not necessarily promote an effective evaluation, prioritization, and, therefore, implementation of system change controls in organizations. Alarming facts within the literature trigger analyses and identification of additional methods to assist organizations in protecting their sensitive and critical information. This research proposes a quantitative approach to assist management in evaluating system change controls using the Analytic Hierarchy Process. Through a case study, the approach is proven successful in providing a way for measuring the quality of system change controls in organizations.

Abstract Maintenance preventive (PM) on equipment is a very important issue for an effective manufacturing system, since the improper MP might cause many problems affecting productivity, precision, flexibility and quality of the products negatively. On the other hand, analysis of MP equipment among many alternatives can be a multicriteria decision making (MCDM) problem. In this study, an integrated approach which employs analytic hierarchy process (AHP) and preference ranking elements, is proposed for the MP equipment of 3D printer machine. The AHP is used to analyze the structure of the equipment problems and to determine weights of the criteria, and this method is used to obtain final ranking. Proposed approach is applied to a problem of 3D printer machines to be established a MP strategy.
