Abstract

In the current era of development, infrastructure is one of the main priorities of various countries, including Indonesia, in order to improve people's mobility. One of the initiatives. The Indonesian government is the Solar Street Lighting (PJU-TS) project, which is implemented by PT. Z as a provider. This study aims to determine the best partner for PT. Z in the Solar Street Lighting (PJU-TS) project in the North Sumatra region using the Analytical Hierarchy Process (AHP) method. PT. Z faces challenges in ensuring that the selected partner is able to meet important criteria such as price, financial capability, experience, and responsibility, considering that several previous partners failed to complete the project on target. Through the AHP method, this study analyzed three partners participating in the tender by conducting pairwise comparisons of each criterion. The results showed that responsibility was the main criterion in selecting a partner, followed by financial capability and experience. Based on the AHP calculation, PT. Organisasi Satu Solusi is a suitable partner to execute this project, as it excels in three main criteria: financial (0.219), experience (0.030), and responsibility (0.076).The AHP method has proven to be effective in facilitating a more structured and accurate decision-making process, providing PT. Z with a tool to select the right partner, thereby reducing the risk of delays and errors in the project. Keywords: Analytical Hierarchy Process, Partner Selection, PJU, Responsibility

Abstract

Occupational Safety and Health (OHS) is an important element in the industry to ensure safe and healthy working conditions for workers. PT. X implements OHS through the use of risk assessment forms, especially in the packaging area of ​​the Cold Cutting department. The purpose of this study is to evaluate the risk assessment form used by the company and adjust it to the Job Safety Analysis (JSA) method. The results of the evaluation indicate that the risk assessment form used by the company is not fully detailed in identifying the risks in each job, compared to the JSA method. Therefore, it is recommended that the company adopt a more general and standardized JSA format to improve clarity and understanding, especially for parties outside the company. The implementation of this proposal is expected to improve the effectiveness of risk management and occupational safety, while reducing the potential for accidents in the workplace, thereby increasing the company's overall productivity and operational efficiency.

Abstract

Inventory is one of the key elements in a company's operational success. In an effort to manage inventory well, companies often use systems to track, record and manage their stock. However, it is not uncommon for there to be a discrepancy between the amount of inventory recorded in the system and the actual amount in the storage warehouse. The purpose of this research is to determine the factors that cause discrepancies that occur in the physical data in the Carton Box storage warehouse with the data in the system. The approach method used in this research is the DMAIC method (Define, Measure, Analyze, Improve, Control) as a determinant of the main causal factors in the nonconformity. There are 4 factors that influence stock taking discrepancies during the March 2024 period, Of these 4 factors, the human factor is the factor that most influences stock taking discrepancies. The reason is because the physical pallet and transcript are different, there was an error in inputting data when making the travel document, there was an error in inputting the transcript document, the quantity of goods had not been upgraded and the placement of goods was not appropriate. The main cause seen from the largest percentage is because the physical pallet and transcript are different with the highest percentage being 36%. Keywords: Cartonbox, DMAIC,  Stockopname, Supply

Abstract

In the cigarette paper industry, pallet packaging plays a crucial role in the supply chain. It helps protect cigarette paper from physical damage and environmental factors during transportation and storage. PT BM  faces several challenges, one of which is inefficiency in inventory management, leading to unnecessary costs in production and distribution processes. This study applies the Economic Order Quantity (EOQ) method to determine the optimal order quantity of raw materials, ensuring a smooth production process. The calculation results show that implementing the EOQ method leads to more efficient total inventory costs compared to the company's previous ordering policy. For local pallets, the optimal order quantity changed from 3,600 sets ordered 12 times per year (costing Rp 43,200,000.00) to 514,208 sets ordered only 3 times per year (costing Rp 10,800,000.00). A similar improvement was observed for export pallets, where the order quantity changed from 3,600 sets ordered 24 times per year (costing Rp 52,200,000.00) to 338,327 sets ordered only 3 times per year (costing Rp 6,525,000.00). Additionally, the total inventory cost using the EOQ method was recorded at Rp 38,333,333.33 for local pallets and Rp 36,912,500.00 for export pallets. Keywords: EOQ, Inventory, Pallet Packaging

Abstract

Project delays are a major threat in project management that can result in increased costs and decreased operational efficiency. Therefore, an appropriate planning method is needed to optimize the schedule and reduce the risk of delays. This study aims to analyze the critical path and determine the optimal time in the H₂S Analyzer Upgrade project using the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT). CPM is used to identify critical activities, namely contracts (A), field surveys (B), specifications (C), H₂S Analyzer (F), tubing & tubing connections (G), sample conditioning systems (H), accessories (I), electrical & instrument cables (J), bulk materials (K), and spare parts for one year of operation (L). The results of the analysis show that the CPM method estimates the project duration of 235 days. Meanwhile, the PERT method provides an estimate of completion in the range of 221 to 251 days, with a probability of project success being completed in 221 days of 0.14%, and in 251 days of 99.86%. The implementation of this method improves the accuracy of project scheduling and supports efficiency in resource management. The results of this study recommend combining CPM and PERT with other optimization techniques, such as crashing, to improve project time and cost efficiency.
