Abstract

The increasing domestic demand for coal necessitates greater efficiency in logistics systems and supply chains, particularly for mining companies such as PT. Mahakam. This study aims to design a queue system simulation model to optimize the company’s logistics performance by applying queueing theory and utilizing the ARENA simulation software. The research evaluates key variables such as waiting time, queue length, and the utilization rate of unloading facilities, in an effort to address demurrage issues arising from logistical inefficiencies. A mixed-method approach combining quantitative and qualitative data analysis was employed, using both primary and secondary data collected from PT. Mahakam’s logistics operations between January and June 2024. Simulation results indicate that logistics effectiveness can be improved through adjustments in the number of operators, enhancement of unloading equipment, and more structured management of the distribution flow. This research is expected to serve as a foundation for developing simulation-based logistics models in the coal industry and to contribute to the practical application of queueing theory in industrial settings.

Abstract

Flowing concrete, in accordance with ASTM C 1017 is defined as concrete with a slump flow value greater than 19 cm. However, the use of flowing concrete also presents several challenges, particularly in terms of workability and the need for environmentally friendly materials. Various studies have been conducted on the use of substitute or additive materials in concrete mixtures. This study focuses on flowing concrete mixed with Petung bamboo fibers (Dendrocalamus Asper) to determine the effect of varying bamboo fiber percentages on the slump flow value. The study utilizes Petung bamboo fibers as an additive material. The bamboo fibers, cut into lengths of 5 cm and evenly distributed, were mixed into the flowing concrete. The fiber content variations used were 0%, 3%, 3.5%, 4%, and 4.5%, with a superplasticizer (SP) dosage of 1.5% of the cement weight. The slump flow test results indicate that the higher the percentage of bamboo fiber added, the lower the slump flow value.

Abstract

PT. XYZ is a trading company engaged in the multinational distribution of packaging products. To support the sustainability of its operations and performance, PT. XYZ is required to select vendors that can optimally meet its needs. However, in practice, the company does not yet have a standardized method or clear criteria for vendor selection, relying solely on price considerations. This condition may lead to inaccurate decision-making, which can negatively affect company performance. This study aims to evaluate the paper packaging vendor selection process at PT. XYZ using the Analytical Hierarchy Process (AHP) method. The results indicate that price is the most dominant criterion in the decision-making process, with a weight of 0.377. Among the five vendor alternatives analyzed, Vendor B was identified as the most suitable choice, with the highest priority weight of 0.232. These findings are expected to serve as a reference for the company in adopting a more structured and objective vendor selection process in the future.
