Abstract

PT. Weiss Tech has received a project order for the fabrication and installation of coffee packaging production machines from PT.XYZ, scheduled to start on June 19, 2023, with a deadline of June 24, 2024, spanning 54 weeks. The project has been ongoing for 16 weeks with an update indicating that only 20% of the planned progress has been achieved, which suggests that it may not be completed on time. To evaluate the project's performance, the EVM  method will be used to identify critical tasks and reduce the project duration using the Precedence Diagram Method with the help of MS Project software. The evaluation shows negative values for CV and SV variances, as well as performance index SPI<1 and CPI<1, indicating poor project performance. The critical tasks identified include electrical & instrument installation, machine & utility installation, trial work, assembly, quality control, polishing, milling, turning, cutting, and design. Design work has been identified as the most influential on the critical path. By rescheduling the project plan, positive values for CV and SV have been achieved. With the SPI value of 1.13 and CPI value of 1, it can be concluded that future project performance will be completed faster and within budget.

Abstract

Machines are the main element in manufacturing companies, and the role of machine performance is vital in the production process. Downtime problems caused by machine damage can significantly affect company productivity. This research implements the support vector machine (SVM) method for predicting Dry 8 production machine line maintenance, which aims to reduce downtime and increase productivity. The SVM method is known for its high accuracy and low error rate. The evaluation process used four kernel functions: linear, radial basis function (RBF), polynomial and sigmoid. The linear kernel function performed best with 99.8% accuracy, 83% precision, recall, and f1-score. These results show that the SVM method can be a viable solution to improve the efficiency of machine maintenance. Keywords: Confusion Matrix, Machine Learning, Predictive Maintenance, Support Vector Machine

Abstract

In the face of fierce global competition, construction industry companies such as PT XYZ require efficient production machinery to increase productivity. This study aims to evaluate the effectiveness of batching plant machines at PT XYZ using the Overall Equipment Effectiveness (OEE) method and identify improvements through Analytical Hierarchy Process (AHP). The batching plant machine often experiences downtime, especially on line five, which hampers production performance. The OEE method was used to measure three main aspects: availability, performance, and quality, with an average OEE result of 91.34%, which indicates good performance but still below the company's internal standards. Fishbone diagram analysis identified the main causal factors of downtime, while AHP was used to prioritize improvements. The AHP results showed that developing a Standard Operating Procedure (SOP) was the best strategy to reduce downtime, with a weight of 39.8% and consistency of 2%. This research suggests the implementation of SOPs to improve machine effectiveness and maintain optimal productivity at PT XYZ.

Abstract

The distribution of sulfuric acid raw materials is still conducted conventionally and faces challenges regarding the quantity of supply for each product. Therefore, this research was conducted to help create a mathematical model for the distribution of sulfuric acid using the Goal Programming method with the assistance of LINGO 18.0 software. Goal Programming serves to minimize deviations from limits and targets based on priorities in order to maximize profit and achieve the optimal quantity of sulfuric acid in the distribution of sulfuric acid raw materials, as well as to supply several fertilizers containing sulfuric acid. The research results indicate that the annual sales revenue target of 982,937,304 USD was achieved without any deviations. Most of the optimal production targets for products X1 to X8 were also met, with deviation variables showing no shortfall in production quantities for these products. However, for product X2, there remains a production shortfall of 60,096.15 tons to reach the target of 405,823 tons.
