Abstract

The development of technology and mobility has encouraged humans to innovate and create environmentally friendly means of transportation and can reduce dependence on fuel oil which will eventually run out. Currently, transportation equipment using electrical energy is starting to appear as an alternative energy source, including electric bicycles. In this research, electric bicycles were produced equipped with generators and rectifiers to produce additional electrical energy. The generators utilizes the rotation of the front wheels to produce electrical energy which is then channeled through the rectifier and stored in the battery. This research aims to determine the benefits of using generators and rectifiers as additional charging systems for BLDC-based electric bicycles by conducting direct road test of electric bicycles. The result show that the use of a generator and rectifier can increase the distance traveled by up to 2 km. An electric bicycle with a capacity of 24V x 14 Ah can over a distance of 13 km without a generator and 15 km with a generator.

Abstract

Efficient facility layout plays a critical role in improving operational performance, learning effectiveness, and occupational comfort in vocational education workshops. This study examines the redesign of a motorcycle engineering and business workshop at a public vocational high school in Indonesia using the Systematic Layout Planning (SLP) method. The existing layout exhibited inefficient material flow, excessive travel distances, and poor spatial organization, leading to fatigue among students and reduced instructional productivity. A qualitative descriptive case-study approach was employed, supported by direct observation, process mapping, and activity relationship analysis. The SLP procedure was applied through the development of Operation Process Charts, Activity Relationship Charts (ARC), Activity Relationship Diagrams (ARD), and block layout alternatives. The proposed layout demonstrates a substantial reduction in inter-facility travel distance and improved logical sequencing of learning activities. The findings confirm that SLP is an effective and adaptable approach for optimizing educational workshop layouts, contributing to improved operational efficiency and a safer, more conducive learning environment.

Abstract

This study aims to evaluate and improve book inventory management at Al-Madinah Bookstore through the application of ABC and VED analysis methods. The ABC method is used to group books based on sales contribution and frequency of use, thus prioritizing the management of the most valuable books. Meanwhile, the VED method is used to classify books based on their level of importance for the continuity of store operations, namely Vital (V), Essential (E), and Desirable (D). This study uses a qualitative approach with descriptive methods to understand the phenomena in the field, while the data is presented and analyzed quantitatively to provide a statistical overview. The analysis results show that the ABC category is divided into 29% category A, 33% category B, and 37% category C, while the VED classification shows 10% of books are Vital, 63% Essential, and 27% Desirable. The ABC method helps prioritize stock control based on sales value, while VED ensures the availability of vital books based on user importance. The synergistic use of these two methods has proven effective in optimizing inventory, minimizing storage costs, and reducing the risk of shortages of important books, thus supporting the Books tore's business sustainability.

Abstract

Transportation is an essential element in daily life, especially for students with high mobility. This study aims to analyze the choice of transportation modes used by Pahlawan University students on their way to campus. This study highlights student characteristics, factors influencing mode choice, and modeling of transportation mode choice. The method used is a quantitative approach through the distribution of online questionnaires to 100 active student respondents in the 2024–2025 academic year. Data were analyzed using descriptive analysis and binary logistic regression with the help of SPSS software. The results show that the most commonly used mode of transportation is private vehicles, especially motorcycles. The study found that 'pocket money' (allowance) is a significant factor influencing transportation mode choice. The binary logistic regression model provides a robust statistical picture of student mode preferences in the local context of Bangkinang. This research is expected to serve as a reference in making transportation policies on campus and provide input for the development of an efficient transportation system that meets student needs.
