<![CDATA[River sedimentation reduces channel capacity and increases flood risk, making river normalization essential for restoring hydraulic performance. The success of such projects depends substantially on the productivity and operational efficiency of heavy equipment operating under waterlogged conditions. This study aimed to determine the productivity of the Pindad Excava200 pontoon excavator in the Masangan River Normalization Project, Pasuruan Regency. A quantitative applied research design was employed. Primary data were collected through direct field observations of bucket capacity, cycle time, work efficiency, operating hours, equipment condition, and fuel and lubricant consumption, while secondary data were obtained from project documents, equipment specifications, relevant literature, and the 2026 Analisis Harga Satuan Pekerjaan (AHSP). Productivity was calculated for sediment dredging and finishing operations using the observed operational parameters. The results showed that the excavator achieved a productivity of 52.35 m³/hour, equivalent to 418.80 m³/day, during dredging and 67.79 m³/hour, equivalent to 542.32 m³/day, during finishing. Fuel consumption was 0.357 L/m³ for dredging and 0.268 L/m³ for finishing, whereas lubricant consumption was 0.010 L/m³ and 0.007 L/m³, respectively. In conclusion, finishing operations were more productive and resource-efficient than dredging operations because of their shorter cycle times and simpler operational sequences. These findings may support more accurate equipment planning and resource allocation in comparable river normalization and hydraulic engineering projects.]]>
