Abstract

This study aims to analyze the maintenance strategy of railway lines in West Sumatra using the Life Cycle Cost (LCC) approach to determine the most economically efficient and sustainable maintenance option. The main issues raised are the high cost of reactive maintenance and the risk of operational disruption due to track damage. The research method involved collecting construction, operational, and maintenance cost data from railway operators, as well as LCC-based scenario simulations to compare preventive and reactive maintenance strategies. The results of the analysis show that the preventive maintenance strategy results in lower total life cycle costs, compared to the reactive strategy. In addition, the preventive strategy also supports operational sustainability by minimizing the risk of service disruption and improving user safety. SWOT analysis shows that LCC implementation has great potential to improve budget efficiency and support local economic growth, although challenges such as data limitations and natural disaster risks need to be mitigated. This research concludes that an LCC-based approach can be the basis for designing more effective, efficient and sustainable railway maintenance policies. Recommendations include prioritizing preventive maintenance, using monitoring technology, and strengthening supporting policies.

Abstract

One of the problems of urban household waste management is caused by the limited availability of data generated and waste characteristics obtained through standardized methods of collection and measurement. This condition is a challenge for local governments in developing data-based waste management plans. This Community Service Activity (PKM) aims to disseminate methods of collecting and measuring urban household waste to technical apparatus and the community in order to increase technical understanding and participation in waste data collection. The implementation method is carried out through technical guidance involving Lubuklinggau City Environmental Service staff as surveyors and 250 community members as volunteers. Volunteers collected and sorted household waste at the source level for three consecutive days with the assistance of surveyors. The results of the activity showed that the dissemination of the method was able to support the improvement of technical understanding of the apparatus and community involvement in the collection and measurement of household waste in a structured manner. This activity contributes to strengthening collaboration between local governments and the community and can be an initial reference for the implementation of more systematic and sustainable household waste data collection in similar activities in the future.

Abstract

Railway bridge maintenance in Indonesia faces severe budgetary constraints, resulting in inadequate upkeep of aging infrastructure and heightened safety risks. This study evaluates existing maintenance policies, estimates associated costs, and proposes optimization strategies by combining policy analysis, cost-benefit evaluation, and evaluative methods. Focusing on bridges in the Jakarta area, the research uses technical data on bridge age and structural conditions to project a 2025 maintenance cost of Rp7.09 billion. The cost-benefit analysis confirms financial feasibility, as the Net Present Value (NPV) remains positive across multiple discount rate scenarios. The study recommends risk-based regulatory revisions for old bridges and disaster-prone areas, the use of predictive technologies such as IoT, AI, and drones to reduce inspection costs, and innovative financing through public–private partnerships and endowment funds. Additional measures include climate-resilient design standards, prefabricated components, and academic collaboration for cost-effective innovation. Findings demonstrate that risk-based asset management, technological integration, and multi-stakeholder coordination are essential to achieving sustainable and financially viable maintenance. The proposed framework not only supports Indonesia’s railway resilience and safety but also offers a replicable model for other emerging economies facing similar fiscal and infrastructure challenges.Keywords: railway bridge maintenance, cost-benefit analysis. Pemeliharaan jembatan kereta api di Indonesia menghadapi keterbatasan anggaran yang parah, yang mengakibatkan perawatan infrastruktur yang menua tidak memadai dan meningkatkan risiko keselamatan. Penelitian ini mengevaluasi kebijakan pemeliharaan yang ada, memperkirakan biaya terkait, dan mengusulkan strategi optimisasi dengan menggabungkan analisis kebijakan, evaluasi biaya-manfaat, dan metode evaluatif. Dengan fokus pada jembatan di wilayah Jakarta, penelitian ini menggunakan data teknis tentang usia jembatan dan kondisi struktural untuk memproyeksikan biaya pemeliharaan tahun 2025 sebesar Rp7,09 miliar. Analisis biaya-manfaat menegaskan kelayakan finansial, karena Nilai Bersih Sekarang (NPV) tetap positif di berbagai skenario tingkat diskonto. Studi ini merekomendasikan revisi regulasi berbasis risiko untuk jembatan tua dan daerah rawan bencana, penggunaan teknologi prediktif seperti IoT, AI, dan drone untuk mengurangi biaya inspeksi, serta pembiayaan inovatif melalui kemitraan publik–swasta dan dana abadi. Langkah-langkah tambahan meliputi standar desain yang tahan iklim, komponen prefabrikasi, dan kolaborasi akademik untuk inovasi yang hemat biaya. Hasil penelitian menunjukkan bahwa manajemen aset berbasis risiko, integrasi teknologi, dan koordinasi multi-pemangku kepentingan sangat penting untuk mencapai pemeliharaan yang berkelanjutan dan layak secara finansial. Kerangka kerja yang diusulkan tidak hanya mendukung ketahanan dan keselamatan perkeretaapian Indonesia tetapi juga menawarkan model yang dapat ditiru untuk ekonomi negara berkembang lainnya yang menghadapi tantangan fiskal dan infrastruktur serupa.Kata kunci: pemeliharaan jembatan kereta api, analisis biaya-manfaat.
