The road project serving as access to Lambo Dam in Rendubutowe Village, South Aesesa District, Nagekeo Regency, East Nusa Tenggara, uses various types of heavy equipment. The analysis method was carried out by recalculating productivity based on field data and references. Productivity calculations were related to the work volume in order to obtain daily productivity and the required duration. Therefore, theoretical calculation knowledge derived from previous studies was needed. Heavy equipment productivity was then analyzed to determine time efficiency. The subgrade work and pavement layer work on the road project to Lambo Dam, located in Rendubutowe Village, South Aesesa District, Nagekeo Regency, East Nusa Tenggara, had a road length of 6.3 km and a road width of 6 m. However, the observation was limited to a 1 km section from Station (Sta) 0+500 to Sta 1+500. The results obtained were productivity and duration for excavation work using an excavator and dump truck, each at 1785.6 m³/day in 4.52 days. Embankment work using an excavator and dump truck each had a productivity of 892.8 m³/day for 3.82 days, a bulldozer of 43,200 m³/day in 0.07 days, and a Vibro Roller of 168 m³/day in 20.27 days. Base course work used an excavator and dump truck with a productivity of 892.8 m³/day in 2.02 days, a motor grader of 23,372.8 m2/day, and a Vibro Roller of 168 m³/day for 10.71 days. Surface course work used a concrete Mixer truck with a productivity of 43.4 m³/day for 36.72 days. Heavy equipment productivity is influenced by the number of units used; the insufficient use of excavators causes dump truck productivity to be less than optimal in transporting excavation and embankment materials. Likewise, Vibro Rollers are needed in more than one unit so that the project can be completed faster

Coal hauling activities are an important part of mining operation because they affect production continuity, cycle time efficiency, and operational safety. This study aims to analyze the requirements of road support equipment on the coal hauling road from Sector 4 to the new Coal Processing Plant (CPP) at PT. Asmin Bara Bronang, Central Kalimantan. Based on road geometry, traffic density, California Bearing Ratio (CBR), and Unsurfaced Road Condition Index (URCI). The research method used was applied research with a quantitative approach. Primary data ware collected through field measurements consisting of road geometri observations, traffic density observations, Dynamic Cone Penetrometer (DCP) testing to obtain CBR values, and road surface condition assessment using the URCI method. Secondary data were obtained from the company records. The results showed that the hauling road has a total length of 9.1 km with an average width of 16 m, and grade values ranging from -7.68% to 10.52%, which are still below the maximum standard of 12%. Traffic density reached 184 dump trucks/day, for coal hauling and 62 units/day for construction material transportation, indicating high traffic intensity. CBR values ranged from 7% to 100%, showing variations in subgrade bearing capacity. The URCI value ranged from 72,50 to 91.00, indicating fair to good road conditions. Based on the analysis of road conditions and maintenance area requirements, the recommended support equipment for maintaining the hauling road consists of 1 motor grader unit, 1 compactor unit, 1 bulldozer unit, and 1 water truck unit.

Roads in Manokwari City still need a lot to be improved, especially on the Pegaf city boundary road - South Manokwari district, because this road connects the border between the City and the district.... This study aims to calculate the productivity of heavy equipment working on road improvement work, Analyzing the balance of road improvement work tools and knowing the total cost and time required in road improvement projects. So that this research is expected to be useful for optimizing the performance of road sections and being able to provide solutions to problems that occur and can provide an overview of the process of using heavy equipment that is effective and efficient. Productivity is the ability to produce something, so it can be said that heavy equipment productivity is the ability of heavy equipment to produce something per unit of time.
