Abstract

The construction of warehousing and supporting facilities at Juwata Airport has several obstacles that cause delays in the implementation of the work, so a work control method is needed, namely the earned value method by assessing the cost and time performance of project implementation such as Cost Variance (CV), Schedule Variance (SV), Schedule Performance Index (SPI), and Cost Performance Index (CPI) as well as the estimated cost and time of project completion. The purpose of this research is to calculate the amount of cost needed to complete the project of Warehousing Development Package and Supporting Facilities of Juwata Airport on time according to the plan schedule. The method used is the Earned Value Method in evaluating cost performance and time performance. The analysis carried out uses 3 (three) indicators, namely ACWP (Actual Cost of Work Performance), BCWP (Budgeted Cost of Work Performance) and BCWS (Budgeted Cost of Work Scheduled). By using the earned value method, the final project cost estimate obtained from the EAC is Rp. 15,019,062,678.43 and the estimated time / Time Estimate (TE) at week 26 shows 239 calendar days so that the completion time is 28 days late from the contract schedule. And the solution to the delay is to accelerate the work with an additional cost of Rp. 68,970,000. Future research should explore optimization strategies to enhance efficiency in cost estimation and project scheduling.

Abstract

Yos Sudarso Road in Baubau City is a major urban corridor that has experienced a decline in traffic performance due to intensive activities in commercial, tourism, and port areas, resulting in high side friction caused by on-street parking and vehicle maneuvering. These conditions reduce the effective road capacity and degrade the level of service. This study aims to estimate the cost required to improve road performance as a basis for practical and applicable traffic management recommendations. The research employs a quantitative approach by identifying improvement alternatives, calculating work volumes, and estimating costs based on the 2022 Indonesian Public Works Unit Price Analysis (Analisa Harga Satuan Pekerjaan, AHSP) for Road and Bridge Works and the 2024 Baubau City Standard Unit Cost (Harga Satuan Pokok Kegiatan, HSPK). The results indicate that traffic management measures in the form of one-side on-street parking arrangement and installation of no-parking traffic signs require a total cost of IDR 57,000,000.00. This cost is relatively economical and effective in improving road capacity and traffic performance without physical road widening.

Abstract

Road construction in hilly regions of Indonesia presents complex technical and financial challenges due to extreme topographical variations. This study examines the integration of technical design analysis with the Indonesian Standard Unit Price Method (AHSP) to improve cost estimation accuracy and risk management. Using the Batauga–Sampolawa road project in South Buton Regency as a case study, the research analyzes how longsection and cross-section designs influence earthwork volumes and subsequent cost structures. Results indicate that hilly topography necessitates significant slope stabilization measures and unbalanced cut-fill volumes, directly impacting cost distribution. Through AHSP-based cost projection for 2025, the study identifies critical risk factors including fuel price volatility, material classification uncertainties, and equipment productivity in steep terrain. The research demonstrates that an integrated design-cost approach enables more realistic budgeting and proactive risk mitigation in hilly road projects. Recommendations include the adoption of digital terrain modeling, AHSP adjustment factors for hilly conditions, and contingency planning for geotechnical uncertainties.
