Abstract

Purpose: This study examines the influence of bureaucratic leadership style, work culture, and work discipline on employee performance at the Riau Islands Provincial Secretariat, with work motivation as an intervening variable. Research Methodology: Using a quantitative approach, 165 employees were selected as respondents from a population of 279 employees. Data were analyzed using structural equation Modelling (SEM) with AMOS 24.0. Results: The findings show that bureaucratic leadership style and work discipline significantly influence employee performance, whereas work culture has no significant direct effect. All three factors–leadership style, work culture, and discipline—positively and significantly affect motivation, which in turn strongly influences performance. Furthermore, motivation successfully mediated the relationships between leadership style, work culture, discipline, and employee performance, strengthening the overall causal model. Conclusions: Employee performance is primarily shaped by effective leadership, strong discipline, and supportive motivation, with work culture playing an indirect role. Motivation is a central driver that enhances the impact of leadership and discipline on performance outcomes. Limitations: This study is limited to a single public sector organization, with cross-sectional data that may not capture long-term dynamics. Future studies should incorporate other variables, such as teamwork, compensation, and organizational trust. Contribution: This study contributes to the public management literature by demonstrating the mediating role of motivation in linking bureaucratic leadership, culture, and discipline with performance, offering insights for policy and managerial practices in government institutions.

Abstract

Water is a fundamental need for all living things, especially humans, to support survival. Tamangil Nuhuten Village, located in South Kei Besar Sub-district, Southeast Maluku Regency, faces great challenges in meeting the clean water needs of its residents. This study was conducted to evaluate the clean water distribution scheme through technical and economic approaches. The methods used included field surveys, water distribution simulation using EPANET 2.2 software, infrastructure development cost analysis, and a comprehensive assessment of construction time requirements. The results of the analysis show that the hilly topography of the village is the main obstacle in water distribution. To overcome this obstacle, a gravity-based distribution system is recommended. Based on EPANET 2.2 simulation, this system is able to fulfill the community's clean water needs efficiently. The total cost of building the distribution network is estimated at Rp8,202,383,000.00 with a construction time of six months. Furthermore, this research provides an in-depth analysis of the required time allocation for each construction phase to ensure project feasibility and efficiency. This research is expected to be a reference for the government and related parties in designing a water distribution system that is effective, sustainable, and in accordance with the needs of the Tamangil Nuhuten Village community.
