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.
