Abstract

The Bengkulu Health Polytechnic of the Ministry of Health (Poltekkes Kemenkes Bengkulu), located at Jl. Indragiri No. 3, Padang Harapan, Bengkulu City, has experienced continuous growth in student enrollment, resulting in increasing demand for classrooms and laboratory facilities. This study aims to design a new building structure that complies with Indonesian National Standards (SNI) and to evaluate the economic feasibility of the proposed construction project. The research employed reinforced concrete structural design based on SNI 1727:2020 and SNI 2847:2019, combined with an economic feasibility analysis using Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (BCR), Payback Period (PP), and sensitivity analysis. The results indicate that the proposed structural dimensions satisfy the required structural safety criteria, while the economic evaluation yields an NPV of IDR 6.75 billion, an IRR of 10.8%, a BCR of 1.32, and a payback period of approximately 12 years and 4 months, confirming the project's feasibility. Sensitivity analysis further indicates that the project remains feasible under construction cost increases of up to 20%, although higher interest rates approaching 10% reduce its economic margin.

Abstract

Urban flooding represents a systemic risk emerging from the interaction between hydrological hazards, spatial transformation, and infrastructure vulnerability, demanding a management paradigm that transcends conventional engineering responses. This study develops a non-empirical conceptual framework for optimizing risk-based infrastructure management to strengthen urban flood resilience. The framework integrates infrastructure asset lifecycle management, disaster risk theory, and urban governance into a multilayer analytical model that explains causal relations among planning, implementation, maintenance, and adaptive capacity. A systematic literature synthesis and thematic-critical analysis were employed to construct stable conceptual propositions and evaluate internal coherence across disciplines. Findings indicate that preventive planning, adaptive asset management, institutional coordination, and participatory monitoring operate as interdependent mechanisms that reduce system fragility and enhance operational learning. The proposed model provides an analytical structure for evaluating infrastructure effectiveness without dependence on a single empirical context while preserving methodological rigor. This study contributes theoretically by linking risk governance with lifecycle infrastructure management and methodologically by offering a replicable conceptual synthesis for resilient urban systems.
