Abstract

This study aims to determine the effect of service quality on member satisfaction at KSPPS BMT Insan Madani Indragiri Hulu. Service quality is an important factor that affects the level of satisfaction of members in using sharia cooperative services. This study uses a quantitative approach with a survey method. Data was collected through the distribution of questionnaires to 151 members of KSPPS BMT Insan Madani who became research samples. The independent variable in this study is service quality, while the dependent variable is member satisfaction. Data analysis was carried out using simple linear regression to find out the extent to which service quality affects member satisfaction. The results of the study show that the quality of service has a positive and significant effect on member satisfaction. These findings show that the better the quality of service provided, the higher the level of member satisfaction will also increase. This research is expected to be an input for KSPPS BMT Insan Madani in improving the quality of its services in order to achieve optimal member satisfaction.

Abstract

Water resource management faces complex challenges in decision-making, particularly in selecting effective strategies to restore polluted river water quality. Kali Surabaya, as a strategic water source, has experienced quality deterioration due to domestic and industrial pollution, compounded by climate change pressures. Recent assessments indicate mild pollution with several parameters not meeting quality standards. Given resource constraints and rising demands for class I and II raw water, a systematic approach is necessary to determine the optimal recovery strategies. This study employs the Analytic Network Process (ANP) method integrated with the Benefit, Cost, Opportunity, and Risk (BCOR) framework to evaluate interrelated criteria and sub-criteria, identifying strategic priorities specifically in the Kali Tengah segment, which faces considerable pollution pressure. Based on literature review, water quality data, and expert questionnaire results, the primary criteria identified for strategy selection show Benefit (0.4127) as the highest priority, followed by Opportunity (0.23118), Cost (0.1292), and Risk (0.0695). The recommended strategies with optimistic scenario values include establishing communal industrial wastewater treatment (10.8102), applying nanobubble technology (0.6534), and periodic flushing (0.1396). Considering sustainability aspects (economic, social & environmental), this integrated approach aims to enhance long-term water quality management efforts
