Abstract: This study aims to evaluate the comparison between actual and planned labor productivity in the Police Housing Construction Project in Samarinda as a basis for assessing construction Actual productivity data were obtained from field observations, daily reports, and measurement of work volume and duration.
Planned productivity was calculated using the Unit Price Analysis (AHS), project scheduling, and manpower planning.
The results show significant differences between actual and planned productivity in various work categories.
Actual structural productivity ranges from 0.
71 to 1.
20 mA/day, which is lower than the planned productivity of 1.
456Ae3.
21 mA/day.
Finishing works also display substantial deviation, with actual productivity of 27.
52Ae80 mA/day compared to the planned 44Ae135 mA/day.
These discrepancies result in slower progress, increased risk of project delays, and reduced time management efficiency.
Key factors contributing to productivity gaps include field conditions, weather disturbances, material mobilization, worker experience, and coordination effectiveness among subcontractors.
The findings highlight the importance of periodic productivity control and improved field management to meet planned targets.

INTRODUCTION
The success of a construction project is greatly influenced by the workforce's ability to complete work within the established timeframe and volume [Adi & Mulia, 2.
In the Police Dormitory Construction project in Samarinda City, labor productivity is a critical indicator determining the efficiency of work implementation.
In the planning documents, labor productivity has been calculated based on the Unit Price Analysis (AHS), project scheduling, and technical provisions in accordance with PUPR Ministerial Regulation No.

However, the dynamics of construction implementation in the field often result in discrepancies between planning and implementation [Ginting & Lubis, 2.
Actual productivity that is lower than planned is one of the causes of project delays.
Some structural and architectural projects show quite high productivity deviations, ranging from 37Ae60%.
This condition not only affects the efficiency of implementation time but also results in increased operational costs due to extended work durations [Suryani & Fachrudin, 2.
Several factors contribute to low actual productivity in the field, including unpredictable weather conditions, delays in material supplies, mobilization obstacles, and ineffective coordination between sub-projects [Nugraha & Pratama, 2022.
Wijaya & Prakoso, 2.
Given the high deviation, a comparative evaluation of actual and planned productivity is crucial for identifying implementation weaknesses, analyzing the causes of inefficiencies, and providing recommendations for productivity improvements in future projects [Yusuf & Rahman, 2.
Therefore, this study contributes to a comprehensive understanding of workforce effectiveness and project control strategies for the construction of the Police Dormitory in Samarinda City.

RESULTS AND DISCUSSION
In this study, the evaluation focused on the level of alignment between actual and planned productivity and the effectiveness of its implementation.
The evaluation results were used to assess workforce performance, identify obstacles, and improve workforce management.
Actual Productivity Evaluation Results Observations of actual labor productivity were conducted on structural and finishing work.

Structure C Planned productivity ranges from 1,456Ae3.
21 mA/day Finishing C Planned productivity ranges from 44Ae135 mA/day This calculation becomes a contractual reference and the basis for planning the duration of each work item.
Actual vs Planned Comparison The comparison shows significant deviations for all job categories:
Deviation of Structural Work The largest deviations were seen in the casting of plates .

This indicates that the implementation of the structure faced significant obstacles in the field.
Deviation of Finishing Work The finishing deviation is lower, ranging from 31Ae41%, which is relatively more stable than the structure.

Evaluation of Factors Causing Productivity Mismatch Analysis reveals five core factors:
Material Factors C Delays in distribution of ceramics, cement, paint, iron Remote storage locations cause high waiting times Time Management Factors C Effective working hours are only 5Ae6 hours/day due to preparation and rest time Overlapping work between floors Equipment Factors C Manual tools dominate, such as small mixers or simple cutting tools C Lack of equipment during peak hours Labor Factor Differences in skills between individuals C Lack of field supervision Environmental Factors Rainy weather hamper casting work Evaluation of the Impact of Productivity Differences Impact on Time Deviation causes cumulative delays during:
10Ae18 day on structural work 5Ae12 day on finishing work Impact on Costs C Labor cost efficiency decreases C Overtime costs increased to 8Ae12% Risk of increased material costs due to delays Impact on Project Management C CPM schedule must be revised C Need for additional workers on some critical items C Supervision must be more intensive General Discussion From the overall results obtained, it can be concluded that:
Actual productivity is much lower than planned due to dynamic field conditions and far from ideal assumptions.
Evaluation shows that productivity is most influenced by logistics management and field The Spirit of Society Journal Volume 9.

Project efficiency can be increased by rearranging work methods, improving material distribution, and close supervision.
CONCLUSION
Based on the evaluation of labour productivity on the Samarinda City Police Dormitory Construction Project, it can be concluded that there is a significant productivity gap between actual and planned conditions.
Measurement results indicate that actual productivity on structural and finishing work is far below the planned productivity figures prepared based on the Unit Price Analysis (AHS) and the project schedule.
This indicates that implementation in the field is not fully in line with the initial Actual structural productivity only reached 0.
71Ae1.
20 mA/day, compared to the planned productivity of 1,456Ae3.
21 mA/day, while actual finishing productivity was between 27.
52Ae80 mA/day, still below the planned productivity of 44Ae135 mA/day.
This difference reflects a productivity deviation of 40Ae60%, which has the potential to impact overall work time and cost efficiency.
Factors causing deviations in productivity between actual and planned include:
Suboptimal workforce management, especially regarding task division, supervision, and worker absences.
Inconsistent working methods, where implementation in the field does not fully follow planning .
External disturbances, such as weather and material delays that hamper the work rhythm.
Capacity and skills of the workforce, where some workers lack experience so that work speed is below planned standards.
This evaluation confirms that increasing productivity requires improvements in planning, monitoring, and work control.
Project management needs to adopt a strategic approach through improving human resource quality, optimizing the material supply chain, adapting to more efficient work methods, and implementing regular monitoring based on productivity performance indicators.
These steps can minimize the gap between actual and planned productivity, allowing projects to be completed more effectively and on target.
