Abstract

The energy source of the converted electric motorcycle is from the battery. The type of battery used is lithium-ion with a capacity of 72 V/20 Ah. The purpose of this research is to increase the efficiency of electrical power consumption required by the driving motor from previous research, where the electrical power consumption of the converted electric motorcycle with a v-belt power transmission at a driving speed of 50 km/h is 724 Watts. It is only able to cover a distance of 99 km. The method used in this research is to test the electrical power consumption of the converted electric motorcycle with a synchronous belt power transfer. The results of the test show that the converted electric motorcycle with a synchronous belt power transfer consumes only 305 Watts of electrical power at a speed of 50 km/h. This means that the efficiency of electrical power consumption increases by 120% compared to the v-belt power transfer, and the driving distance at a speed of 50 km/h is 235 km.

Abstract

The bicycle manufacturing industry is a sector that continues to experience growth as public awareness of the importance of a healthy, environmentally friendly lifestyle increases, and interest in cycling grows. In the production process, the Welding Division plays a crucial role as it is responsible for assembling the main components of bicycles, namely the frame. This study focuses on demand forecasting in this division so that the company can determine production targets more accurately. The single moving average method was chosen as the forecasting technique because it is suitable for limited data conditions, both for production and sales needs. The researchers divided this method into three variations: forecasting with a 2-month, 3-month, and 4-month period. The analysis results showed that the 2-month single moving average method provided the most accurate results with a mean absolute percentage error of 28%, which is lower than the other methods. Overall, the average production in the Welding Division reached 54,050 units.

Abstract

This study aims to analyze the optimization of work process time in the welding division using the Critical Path Method (CPM). This method is used to identify the critical path and calculate the slack variable for each production activity. The data used are the sequence of activities, dependency relationships, and production process time in 2024. The analysis process is carried out through the preparation of a network diagram, forward pass and backward pass calculations, and determining the slack value. The results show that the critical path is found in the series of activities A–B–C–D–E–F–G–H with a total duration of 17 minutes. All activities have a slack value of 0, so any delay has the potential to delay the entire process. These findings confirm that the production process in the welding division has been running optimally. The company is advised to maintain the existing work pattern and ensure the appropriate duration of each activity to maintain production efficiency.

Abstract

Traffic accidents remain a global challenge, with WHO reporting high mortality rates among individuals aged 5–29 years. In Indonesia, accident trends also show a consistent increase, with an average rise of 6.90% per year from 2019 to 2023, predominantly involving motorcycle riders. This condition highlights the importance of cognitive factors, situation awareness (SA), which plays a role in recognizing, understanding, and predicting events while riding. This study aims to investigate the SA levels of motorcycle riders based on riding experience, age, and time of day using Situation Present Assessment Method (SPAM). This study involves laboratory research and uses primary data in quantitative. The findings indicate that younger and less experienced riders exhibit lower SA levels, and that SA performance at night is lower than in the morning. These results recommend the need for safety training programs that focus on SA development, the preparation of simulation-based educational modules, and the establishment of minimum SA standards for obtaining a driving license.

Abstract

This study aims to accurately forecast short-term electrical energy demand in a Jabodetabek industrial facility to support sustainable manufacturing and precise utility management. To address the highly dynamic and non-stationary nature of energy consumption, this research applied Holt’s Double Exponential Smoothing method. A 24-month historical dataset, spanning from January 2024 to December 2025, was analyzed to generate a six-month operational projection. Model performance was rigorously evaluated using Mean Absolute Deviation (MAD), Mean Square Error (MSE), and Mean Absolute Percentage Error (MAPE). The forecasting demonstrated outstanding predictive accuracy, yielding a MAPE of 1.26%, a MAD of 20,79, and an MSE of 690.40. The projection indicates a consistent linear escalation, with energy demand expected to reach 2.020,72 MWh by mid-2026.These findings confirm that Holt’s algorithm effectively captures underlying linear trends without seasonal behaviors. Integrating this precise mathematical model into standard procedures provides crucial early warning signals for capacity planning, mitigates utility shortages, and strongly supports the strategic mandate of green operations.
