Optimalisasi Anggaran Pemeliharaan Gedung Publik Berbasis Life Cycle Cost (Lcc) Terintegrasi Konvensional-Digital

Abstract

The high maintenance budget requirements for traditional market buildings, as part of the city's public buildings, in managing maintenance costs efficiently throughout the building's lifespan. The research objective is to optimize the maintenance budget thru a Life Cycle Cost (LCC) approach that integrates conventional maintenance cost calculations (independent calculations and AHSP) and estimates from digital applications (APK), resulting in the most cost-effective scenario option over the lifecycle. The method used is a quantitative-qualitative combination: preparing a budget for each method, mapping work items (crosswalk), and then calculating real-based LCC with a 20-year horizon (r≈2.639%), including PV O&M (2%×C₀/year) and periodic costs/replacements according to maintenance policies. The definition and application of LCC follow the total cost of ownership framework from the initial phase to maintenance, with conventional and digital integration in the study object, Traditional Market Building X. The results show consistent NPV comparisons for LCC. Maintenance cost calculations using a digital application (APK) resulted in the lowest total LCC compared to AHSP and manual calculations, primarily because the smaller C₀ reduced PV O&M and periodic/replacement costs based on the percentage of components. In this case study, the value of APK is recorded as approximately Rp39.28 million, which is less than AHSP (approximately Rp67.63 million) and Manual (approximately Rp120.71 million). The research findings confirm that the integration of conventional and digital methods in calculating the LCC value is effective as a basis for making maintenance budget decisions, thus providing transparent technical and economic justification for local governments and traditional market managers to optimize and improve efficiency.
