Abstract

This research examines the development of a responsive website front end for shoe laundry services using the SCRUM method. In the context of the development of information technology, especially the internet, web-based websites are important for human life, but there are still some people who do not understand the development process. This research aims to introduce and implement the principles of responsive website design, as well as facilitate understanding and skills in website development to shoe laundry businesses. The SCRUM method was chosen to ensure website development in accordance with user needs and rapid market dynamics. The results include the development of a responsive and user-friendly front end website using HTML, CSS, JavaScript, and ReactJS. This project provides benefits to the campus as an example of the application of technology in the industrial world and increases the researcher's knowledge in web development and the SCRUM method.

Abstract

This study aims to design, develop, and test a prototype of an automatic trash bin based on HC-SR04 ultrasonic sensors and Arduino Uno R3 microcontrollers to improve cleanliness, efficiency, and awareness of waste management at the LP3I Polytechnic in Medan. This system is designed to detect the presence of users at a distance of less than 30 cm using an ultrasonic sensor, which then triggers the SG90 servo motor to automatically open the trash can lid and display information on capacity status and full warnings via a 16x2 LCD screen. After a 2-second delay, the lid will close again to prevent the spread of odors and maintain environmental hygiene. The prototype was developed through a research approach that included direct observation in the campus area, literature studies from reliable sources, and system design with hardware and software integration. Testing was conducted at strategic locations such as rest areas and campus corridors for 10 days, involving 100 trials with 10 daily tests per location. The test results showed a system effectiveness rate of 92%.
