Re-design of Facilities at PT. Apindowaja Effective Persada with Group Technology Approach

Introduction

PT. Apindowaja Effective Persada is a manufacturing company that specializes in producing spare parts for machines in the palm oil industry. Located in Medan, North Sumatra, the company produces a wide range of spare parts, including mainshafts, cones, cone guides, pulleys, hydraulic cylinders, intermediate gears, gearboxes, protect nuts, screw worms, and others. Despite its focus on producing high-quality spare parts, the company faces several challenges in its production process. One of the main issues is the similarity of the form and process of spare parts production, which leads to high moments of material transfer and irregularity in production flow. This results in a decrease in operational efficiency and reduces the effectiveness of the flow of materials in the factory.

The Need for Re-design

The current machine settings at PT. Apindowaja Effective Persada use the process (process layout) approach, which is based on the similarity of functions. However, this approach has several limitations. The similarity of the form and process of spare parts production causes high moments of material transfer and irregularity in production flow. This results in a decrease in operational efficiency and reducing the effectiveness of the flow of materials in the factory. To overcome this problem, the company needs to re-design the location of the facilities, especially in the production department.

Group Technology Approach and Blocplan Method

One approach that can be applied to re-design the facilities at PT. Apindowaja Effective Persada is the Group Technology (GT) approach. This approach focuses on grouping products based on the similarity of their processes and characteristics. By implementing group technology, it is expected to reduce the moment of material transfer and increase the flow of production processes. In addition to the GT approach, the company also implements the Blocplan method. This method serves to redesign the factory layout by considering the closeness between various production facilities. With this method, companies can minimize distance between work stations and speed up the overall production process.

Implementation of Rank Order Clustering (ROC)

In re-designing the location of the facility, the Rank Order Clustering (ROC) method is used to identify product groups based on processing frequencies. By using a ROC, companies can group similar spare parts, so that the arrangement of machinery and production equipment can be done more effectively. The ROC method is a useful tool for identifying product groups and arranging machinery and production equipment in a way that minimizes material transfer and maximizes production flow.

Results of the Re-design

From the results of the calculations carried out, it is known that the rearrangement of the facility of the facility results in a decrease in the moment of transfer of materials to 39.6%. In addition, the application of the Blocplan algorithm shows the value of closeness between facilities of 0.45. This value indicates that the new layout is more efficient and provides better flow of materials in the factory.

Positive Impact on the Production Process

The layout of the proposal produced through this approach not only reduces the moment of displacement, but also shortens the time of the process of working on the entire spare parts. This certainly has a positive impact on company productivity and can increase competitiveness in the market. With better settings, employees can work more efficiently, and stopping time production can be minimized.

Conclusion

In conclusion, the re-design of the facility with the Group Technology approach supported by the ROC and Blocplan methods at PT. Apindowaja Effective Persada is the right solution to improve production efficiency and effectiveness. With this step, companies can meet market demand more optimally, as well as improve service quality to customers. The implementation of the GT approach and the ROC and Blocplan methods has shown significant results in reducing material transfer and increasing production flow. This approach can be applied to other manufacturing companies that face similar challenges in their production process.
