Abstract

Motorcycle riders are basically required to drive with awareness of orderly behavior on the road. However, the fact is that many motorbike accidents are still caused by negligence, one of which is drowsiness while driving. This research aims to develop a fuzzy logic-based drowsiness prevention tool for motorcyclists. This tool goes through 4 stages of testing, namely power supply, sensor, microcontroller and actuator. The results of testing are that the power supply on this tool functions well, the tools on the motorbike and helmet function well according to the program designed on the microcontroller, the pulse sensor designed for motorbikes does not function as it should, so for temporary research the Max sensor is used 30100 as a pulse reader, buzzer, vibrator and relay in this tool functions well and is more accurate compared to previous research according to the fuzzy rules that have been programmed. The use of sensors on the wrist has proven to be effective in detecting pulse, so that the accuracy of sleepiness readings is in line with pulse readings, namely 100%, which is a follow-up to previous research. Fuzzy logic on the device influences the microcontroller to work accurately according to what has been programmed.

Abstract

This study explored the entrepreneurial interest in e-commerce among vocational high school students in the Motorcycle Engineering and Business program, with a focus on motorcycle spare parts sales. A descriptive quantitative approach was applied through a survey method involving 80 students. A questionnaire was employed to assess the level of entrepreneurial interest as well as the influencing factors, both intrinsic and extrinsic. The findings indicated that students’ interest in e-commerce entrepreneurship was at a moderate level, with intrinsic factors accounting for 56.98% and extrinsic factors for 43.02%. Motivation emerged as the most dominant intrinsic factor (14.51%), followed by perception, enjoyment, experience, and character. On the extrinsic side, the family environment exerted the strongest influence, followed by school and community. These results underscored the need to strengthen students’ digital entrepreneurial interest through contextual learning, hands-on activities, and supportive environments. The study also reinforced the relevance of Self-Determination Theory in explaining how intrinsic motivation influenced students’ entrepreneurial intentions in the digital economy.
