Abstract

A bicycle control system has been made using the PWM principle to adjust the motor speed byusing a distance sensor as a safety system on the highway. The background of this research,electric bicycles have still not installed a safety system that directly connects motor speed usingthe principle of Pulse Width Modulation (PWM). The control system that is designed are addedan ultrasonic sensor on the front of the bicycle that serves to measure the distance of the rider'sbicycle with other vehicles. Variation of the specified distance is equal to ? 1 meter, ? 2 meters,? 3 meters, and > 3 meters, so the risk of accidents on the highway can be decreases. Thepurpose of this research is design and build a control system using the PWM principle toregulate the rotation speed of the motor and safety systems on electric bicycles. The results ofthis research are in barrier-free condition, electric bicycles can drove with average maximumspeed of 28 km/hour. The speed of an electric bicycle that is affected by the front ultrasonicsensor at a high speed at a distance of 3 meter, 2 meter and 1 meter, respectively; 20.6km/hour; 15.5 km/hour; and 5 km/hour. The right ultrasonic sensor has succeed to activatingthe buzzer at a distance of ? 100 cm.

Abstract

Energy is a fundamental force driving transformative processes across various domains. It is perpetual and adheres to the law of energy conservation, remaining indestructible. However, the challenge lies in the finite nature of conventional energy sources, which convert energy for intended purposes and cater to diverse needs, often escalating the overall cost. Among the commonly employed energy sources, batteries play a pivotal role. This study explores the viability of avocado seeds as potential electrolytes in dry batteries. The objectives are to assess the effectiveness of avocado seeds as electrolytes and to investigate the impact of solution concentration and composition on the generated electrical energy. A dry element battery, known for converting chemical energy into electrical energy through Redox (Reduction-Oxidation) electrochemical reactions, serves as the experimental focus. Using a quantitative approach with laboratory experiments, five treatments were administered, featuring different ratios (1:1, 1:2, 1:3), a negative control with avocado seeds, and a positive control with salt. The bio-battery effectiveness assessment revealed that the P4 composition (negative control with avocado seeds) exhibited the highest initial voltage of 3.4 V and an extended runtime of 156 hours. In summary, this research underscores the potential of avocado seeds as electrolytes in dry batteries, supported by observations of voltage levels and ignition times.
