Abstract

The Architecture, Engineering, Construction, and Operations (AECO) industry has shown high interest in the use of Building Information Modeling (BIM) for Facility Maintenance Management (FMM). The opportunity to use BIM for the operational activities of building facilities is very large, but the use of BIM in FM is still far behind compared to the implementation of BIM at the design and construction stages. This research is intended to test the tile floor maintenance method and create visualizations in animative form and apply them in virtual learning with evaluation based on the Technology Acceptance Model (TAM). The results of the student t-test statistical test showed that there was a very significant effect of the Ceramic Floor Care Method Learning Media on increasing user knowledge in 5 aspects (learning objectives, knowledge, materials, service quality, and appearance). The test results by media experts on the aspects of language, display, and service quality obtained the "very feasible" category, while the test results by material experts on the aspects of learning objectives, material delivery, and material selection also obtained the "very feasible" category to be applied in learning/ training. It is hoped that the results of this research can trigger the formation of an open access BIM object library.

Abstract

Distribution is a crucial component of a company’s operations that significantly impacts total costs. PT Ngadi Makmur, a company engaged in fertilizer distribution, faces challenges in optimizing distribution costs to enhance efficiency and competitiveness. This study aims to optimize fertilizer distribution costs using the North West Corner (NWC) transportation method. The method is chosen for its simplicity in providing an efficient initial solution for distribution problems. The research utilizes fertilizer distribution data from PT Ngadi Makmur, including transportation costs, shipment quantities, and demand at each destination. The analysis is conducted by applying the NWC method to obtain an initial solution, further refined using the stepping stone method to achieve optimal results. The findings reveal that the NWC method provides an initial solution close to optimal, resulting in a 12% reduction in distribution costs compared to the company’s previous traditional methods. This optimization not only reduces operational expenses but also enhances the speed and accuracy of deliveries. The study recommends implementing other, more advanced transportation methods, such as the Vogel method, for further development. Through this optimization, PT Ngadi Makmur can improve efficiency and support sustainable business practices in the competitive fertilizer market.
