Abstract

Effective drainage systems are crucial for managing stormwater, preventing flooding, and promoting urban sustainability. However, rapid urbanization and climate change exacerbate drainage challenges in cities like Semarang, where poor infrastructure often struggles with heavy rainfall and tidal floods. Despite proactive efforts, such as participation in the Water as Leverage program, the city's drainage system faces significant challenges, including financial limitations and poor coordination between stakeholders. This study applies the Organization for Economic Co-operation and Development (OECD) Water Governance Principles to analyze the governance framework of Tenggang drainage system, identifying gaps and proposing improvements. A qualitative, descriptive approach was used, collecting primary data through interviews with government and community stakeholders, alongside secondary data from literature and document analysis. The results highlight the need for clearer roles and responsibilities, better coordination across government levels, and enhanced public participation. It was also found that integrating policies across sectors and fostering innovation could significantly improve the system's efficiency and sustainability. Additionally, strengthening transparency, trust, and community engagement is essential for achieving more inclusive governance. This study concludes that aligning Semarang’s drainage management with the OECD principles can lead to a more resilient, efficient, and sustainable system that addresses both current challenges and future water management needs.

Abstract

Construction projects often face challenges in the form of delays and cost overruns due to discrepancies between plans and actual implementation. The Dormitory Building at Airlangga University Campus C in Surabaya was selected as a case study to comprehensively evaluate project performance. The purpose of this study is to evaluate time and cost performance using the Earned Value Management (EVM) method to provide an accurate picture of the deviations that occur and as a basis for project control recommendations. This study uses a descriptive quantitative approach with secondary data in the form of weekly progress reports, basic schedules, and project financial records. The analysis was conducted through the calculation of EVM indicators, which included Planned Value (PV), Earned Value (EV), Actual Cost (AC), Cost Performance Index (CPI), Schedule Performance Index (SPI), and Estimate at Completion (EAC). The results show that the project experienced delays with an average Schedule Performance Index (SPI) value of 0.92, or approximately 8% behind schedule, while the average Cost Performance Index (CPI) value of 1.05 indicates cost efficiency of 5% compared to the initial budget. The Estimated Cost at Completion (EAC) projects a completion cost of IDR 94.8 billion, which is lower than the contract value of IDR 95.6 billion. Therefore, the project is still under control in terms of cost but requires accelerated work to meet deadlines, while the application of EVM has proven to be effective as an early warning tool and a basis for decision-making in construction project management.
