Abstract

This study aims to examine the marketing strategy of clean water services implemented by the Community Self-Help Group (KSM) Banyu Bening in Taman Kedaung Housing, South Tangerang, with a particular focus on building consumer trust in potable water quality. The research adopts a descriptive qualitative approach, with data collected through in-depth interviews, field observations, and documentation. In practice, KSM Banyu Bening conducts regular water quality testing through a local public health laboratory as a form of quality assurance and as a communication tool to inform the community. The findings reveal that the effectiveness of the marketing strategy is driven by transparency in communicating test results, the intensity of direct interaction with customers, and the utilization of community-based media for continuous information dissemination. This approach has proven effective in enhancing consumer trust and strengthening customer loyalty toward the clean water service. The study offers practical insights for developing trust-based marketing strategies in community-managed clean water services.

Abstract

Climate change mitigation requires higher education institutions to identify and control carbon emission sources generated by their operational activities. Previous studies in university environments have generally focused on carbon footprint quantification without systematically analyzing the root causes of emissions and identifying priority improvement actions. Therefore, this study proposes the integration of Carbon Footprint assessment with the Seven Tools approach within a Statistical Process Control (SPC) framework to identify dominant emission sources, analyze root causes, and formulate emission reduction strategies. The study employed a quantitative descriptive method using one-year operational data consisting of electricity consumption and fuel usage. Carbon emissions were calculated based on IPCC emission factors and subsequently analyzed using selected Seven Tools, namely histogram, Pareto diagram, and fishbone diagram. The results indicate that electricity consumption (Scope 2) contributed 1,112,996.46 kg CO₂/year or 98.23% of total emissions, whereas fuel consumption (Scope 1) accounted for only 20,066.67 kg CO₂/year or 1.77%. Fishbone analysis revealed that the dominant causes originated from human behavior, inefficient equipment, lack of energy management procedures, and dependence on fossil-based electricity. The novelty of this study lies in applying Seven Tools, traditionally used for quality improvement, to carbon emission management in higher education institutions. The findings provide practical guidance for energy management programs and demonstrate that electricity efficiency and renewable energy adoption could potentially reduce institutional carbon emissions by more than 20–30%.
