Analysis of the Remaining Construction Material using Pareto's Principle and Fishbone Diagram: A Case Study of the Parsoburan Puskesmas Weight Rehabilitation Project in Pematangsiantar City

Introduction

In the world of construction, material plays a crucial role in determining the total cost of the project. With contributions ranging from 40 to 60% of the total cost, the use of efficient material is the key to achieving project success. However, during the construction process, it is often found that the remaining material that can be detrimental in terms of cost and efficiency. One concrete example is a severe rehabilitation project at Parsoburan Health Center, Pematangsiantar City, where many remaining materials such as bricks, reinforcement iron, mild steel, broken stones, and sand are produced.

The Importance of Understanding the Cause of the Remaining Material

The importance of understanding the cause of the remaining material is the focus in this research. By applying Pareto's Principle, which focuses on identifying 20% of the main causes that produce 80% of the problem, as well as Fishbone Diagram to identify the causal factors, we can find effective solutions to reduce the remaining material. This approach is essential in the construction industry, where the use of efficient material can significantly impact the project's success and reduce unnecessary costs.

The Results of the Residual Analysis of the Material

Based on the analysis using Pareto’s Principle, it was found that the construction material that left the most cost was concrete iron and Span Deck Metal Type Rib. The cost of the remaining material for concrete iron reaches Rp 17,156,970.00, while for the Span Deck Metal Type RIB is Rp 2,296,976.88. This shows that the main focus in reducing the remaining material must be directed to these two types of material. The high cost of these materials can be attributed to various factors, including the complexity of the construction process and the lack of efficient material management.

The Cause of the Remaining Material

Through the use of fishbone diagrams, deeper analysis of the factors that cause the remaining material reveals several main categories, namely:

Method (Method): The work process that is not standardized can cause inaccuracies in the use of material. This can be attributed to the lack of clear guidelines and procedures for material usage, leading to confusion and errors among construction workers.
Manpower (labor): Lack of training or experience workers can contribute to errors in the use and calculation of material. This can be addressed by providing regular training and workshops for construction workers to improve their skills and knowledge.
Machine (machine): Inadequate or inadequate equipment can cause material damage during the construction process. This can be addressed by investing in new and efficient equipment, as well as regular maintenance to ensure that equipment is in good working condition.
Material (material): Poor quality material can also be a cause of high material remaining. This can be addressed by sourcing high-quality materials and ensuring that they are properly stored and handled.
Measurement (measurement): The inappropriate measurement process often results in waste of material. This can be addressed by implementing a more accurate and efficient measurement process, such as using digital measuring tools.

Solution to Reduce the Remaining Material

To minimize the remaining material produced during the project, several strategic steps can be implemented:

Good material planning: Creating a more mature and detailed program related to material requirements thereby reducing the possibility of over-ordering or waste.
Intensive team coordination: Improve communication between teams in the field and planning so that information related to the use of materials can be delivered accurately and on time.
Careful checking and measurement: Making more thorough and periodic measurements of the material to ensure efficient use.

Conclusion

The rest of the construction material in the Parsoburan Puskesmas rehabilitation project shows how important effective material management is. By applying the Pareto and Fishbone Diagram analysis, we can identify the source of the problem and take concrete steps to reduce waste. Thus, the efficiency of material use can be increased, which will ultimately support the success of the project and reduce unnecessary costs.

Recommendations

Based on the findings of this research, the following recommendations are made:

Implement a more efficient material management system, including good material planning and intensive team coordination.
Provide regular training and workshops for construction workers to improve their skills and knowledge.
Invest in new and efficient equipment, as well as regular maintenance to ensure that equipment is in good working condition.
Source high-quality materials and ensure that they are properly stored and handled.
Implement a more accurate and efficient measurement process, such as using digital measuring tools.

By implementing these recommendations, construction projects can reduce the remaining material and increase the efficiency of material use, ultimately supporting the success of the project and reducing unnecessary costs.
Frequently Asked Questions (FAQs) about the Analysis of the Remaining Construction Material using Pareto's Principle and Fishbone Diagram

Q: What is Pareto's Principle and how is it used in construction projects?

A: Pareto's Principle, also known as the 80/20 rule, states that 20% of the causes produce 80% of the problems. In construction projects, this principle is used to identify the main causes of the remaining material and focus on solving those problems first.

Q: What is a Fishbone Diagram and how is it used in construction projects?

A: A Fishbone Diagram, also known as a Cause-and-Effect Diagram, is a tool used to identify the causes of a problem. In construction projects, it is used to identify the causal factors of the remaining material and develop solutions to address those factors.

Q: What are the main categories of causes of the remaining material in construction projects?

A: The main categories of causes of the remaining material in construction projects are:

Method (Method): The work process that is not standardized can cause inaccuracies in the use of material.
