Abstract

The development of fuel infrastructure in remote areas remains a critical challenge for Indonesia's energy access equity, particularly in regions with limited petrol station coverage relative to population density and vehicle growth. This study aims to analyze the financial feasibility of the construction of petrol stations in Terjun Jaya Village, Betara District, West Tanjung Jabung Regency. The method used is a project feasibility study with a quantitative descriptive approach. The analysis includes aspects of investment costs, revenue projections, and financial indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), Break Even Point (BEP), and Profitability Index (PI). The results of the study show that this petrol station project is financially feasible with a Net Present Value of IDR 7,155,058,232, an Internal Rate of Return of 11.24%, a Payback Period of 4 years and 1 month, and a Profitability Index of 1.62%. The project shows robust market potential supported by regional vehicle population data indicating 176,435 total vehicles in the area requiring regular fuel access. The implications suggest that strategic petrol station development in underserved rural areas can achieve both financial sustainability and significant social impact by improving energy access equity while generating attractive returns for investors.

Abstract

This research aims to model the flood overflow of the Cisanggarung River in Cilengkrang Village using HEC-RAS software. A quantitative method was used with a focus on hydrological and hydraulic analysis. The hydrological analysis includes rainfall calculation, Thiessen Polygon method, frequency analysis, rainfall intensity, Nakayasu method, and planned discharge calculation. Hydraulic analysis was performed using HEC-RAS to model flood overflow. The research results show that the annual rainfall in the study area varies significantly, with the highest recorded rainfall of 1290 mm in 2020. The planned discharge of the Cisanggarung River was calculated at 2137 m³/second. HEC-RAS modeling revealed that the river cross-section capacity is inadequate to contain flood discharge, especially in the upper part near the settlement. Flood distribution occurs at several points along the river with varying levels of elevation. This research provides important information for flood disaster mitigation planning in the Cilengkrang Village area and its surroundings and demonstrates the effectiveness of using HEC-RAS in river flood modeling.
