Abstract

Road paving works play a critical role in supporting economic growth and public welfare, as mandated by Government Regulation No. 34/2006. However, the implementation of such projects is often hindered by road damage and the limited availability of heavy equipment and skilled operators. This study aims to identify the types of heavy equipment used, calculate their production capacity, and analyze the duration of major construction phases. The method applied is time study, using primary data collected from field surveys and secondary data from supporting documents such as construction drawings and literature. The results indicate that each type of equipment showed varying levels of productivity deviation between planning and actual implementation. Dump trucks increased in productivity from 2.98 m³ to 3.49 m³, while motor graders decreased from 366.18 m³ to 317.475 m³. Significant increases were observed in the vibrator roller and air compressor, whereas asphalt finisher, tandem roller, and pneumatic tired roller experienced substantial drops in productivity. The asphalt sprayer maintained consistent performance at 4.980 liters/hour. In conclusion, heavy equipment productivity is significantly influenced by equipment type, field conditions, and operational coordination, all of which are crucial to ensuring timely project completion with quality standards met.

Abstract

A dam is a structure designed to ensure the sustainable availability of water supply. One dam that plays a significant role in this regard is the Keuliling Dam, which makes a major contribution to meeting the water needs of the community. Despite offering numerous benefits, the existence of a dam also poses potential risks that must be properly anticipated. As part of mitigation efforts and maintenance planning, analysis of the buffer zone and greenbelt is essential at Keuliling Dam. This study employs a combination of primary and secondary data to support the evaluation process of the buffer zone and greenbelt conditions at the dam. The aim of this analysis is to assess each component based on observation results using a condition index approach. The assessment process begins with identifying damage in each subcomponent, followed by assigning scores according to the level of damage observed. Based on the analysis results, the condition index for the buffer zone and greenbelt is recorded at level 4, which indicates minor damage. This value reflects the current condition of these two components and serves as a critical reference for the planning and implementation of maintenance activities to ensure the dam's functionality is properly maintained.
