Analysis of the Coefficient of Labor Unit Prices in the Field by Comparing SNI Analysis in the Structure of Government Buildings

Introduction

In the implementation of construction projects, labor and materials are vital components that determine the success of the project. The quality of the workforce and good material will produce a satisfying final result. One important factor in the calculation of construction costs is the work unit coefficient. This coefficient reflects labor efficiency in completing a type of work. The work unit coefficient is a crucial factor in determining the cost of labor in construction projects, and it is essential to have accurate and realistic values to ensure the success of the project.

Background of the Study

The Indonesian National Standard (SNI) provides a standard for the work unit coefficient, which is widely used in the construction industry. However, the SNI coefficient may not reflect the actual working conditions in the field, which can lead to inaccurate cost calculations. This study aims to analyze the coefficient of work units for the work of a brick and plastering pair on the government building project using the Time and Motion Study Analysis method.

Research Methods

This study uses the Time and Motion Study Analysis method with the following steps:

Field Observation: Researchers directly observe the process of implementing the work of the pair of brick and plastering in the field.
Recording of work time: The time needed by workers to complete one type of work is recorded carefully.
Data analysis: Working time data obtained is analyzed and calculated to get the work unit coefficient.

Research Result

Field research shows that the coefficient of work units on government building projects is different from those listed in SNI. The following are the results of the comparison of the work unit coefficient between the field and SNI:

Type of Work	Field Coefficient	SNI Coefficient
Bata 1 Bata 1 Bata Floor 1	Workers: 0.381, Magicians: 0.171	Workers: 0.400, Magic Cions: 0.180
Pair of brick 1/2 brick 1st floor	Workers: 0.274, Magicians: 0.114	Workers: 0.300, Magic Cone: 0.120
Plastering 1st Floor	Workers: 0.261, Magic: 0.101	Workers: 0.280, Magicians: 0.110
Bata 1 Bata Pair 2 Floor 2	Workers: 0.362, Magicians: 0.152	Workers: 0.400, Magic Cions: 0.180
Pair of brick 1/2 brick 2nd floor	Workers: 0.262, Magicians: 0.112	Workers: 0.300, Magic Cone: 0.120
Plastering 2 Floor	Workers: 0.262, Magicians: 0.105	Workers: 0.280, Magicians: 0.110

Analysis and Conclusion

The results showed that the work unit coefficient obtained from the field was lower than the coefficient listed in SNI. This is caused by several factors, including:

Work efficiency: Workers in the field may have a different level of efficiency with SNI assumptions. Factors such as experience, motivation, and working conditions can affect efficiency. Effective Work Time: Researchers found that effective work time in the field is different from those listed in SNI. SNI sets an effective work time of 5 hours per day, while in the field effective work time reaches 7 hours per day. Working conditions:* Working conditions in the field, such as material accessibility, equipment, and environmental factors, can affect work time and worker efficiency.

Implication of the Study

The difference in the work unit coefficient between the field and SNI has an important implication in the calculation of construction costs. The use of inappropriate coefficients can result in inaccurate cost calculations, so as to harm the project owner or contractor.

Recommendation

Based on the results of the study, the following recommendations can be applied:

Revision of the SNI Coefficient: Pay attention to the field conditions and adjust the SNI coefficient to be more realistic and reflect the actual working conditions. Training and Coaching: Providing training and coaching to workers to be more skilled and improve work efficiency. Evaluation and Monitoring: Performing periodic evaluations and monitoring of the implementation of work in the field to identify the factors that affect work efficiency.

Conclusion

This research is expected to provide useful information for construction industry players in determining the coefficient of work units that are more accurate and realistic, so as to produce appropriate construction costs. The study highlights the importance of considering the actual working conditions in the field when calculating the work unit coefficient. By using the Time and Motion Study Analysis method, this study provides a more accurate and realistic value for the work unit coefficient, which can be used to improve the accuracy of construction cost calculations.

Limitation of the Study

This study has several limitations, including:

The study only focuses on the work of a brick and plastering pair on the government building project.
The study only uses the Time and Motion Study Analysis method to collect data.
The study does not consider other factors that may affect the work unit coefficient, such as material quality and equipment availability.

Conducting a more comprehensive study that includes other types of work and projects.
Using other data collection methods, such as surveys and interviews.
Considering other factors that may affect the work unit coefficient, such as material quality and equipment availability.
