Abstract

The amount of waste in urban areas, especially in Yogyakarta City, is growing, which shows the need for better and cleaner waste management. Traditional trash bins need people to touch them directly, which can make them less clean and uncomfortable to use. This study focuses on creating an automatic trash bin that opens and closes without touching, using an ultrasonic sensor. This system is being developed for the Yogyakarta City Environmental Agency (DLH). The system uses an ultrasonic sensor to sense when something is near, a microcontroller to control everything, and a servo motor to open and close the bin automatically. The research process includes reading previous studies, designing the system, building a prototype, and testing how well it works. The test results show that the system can accurately detect objects within a certain distance and operate the opening and closing function smoothly and quickly. Using this automatic trash bin can help make public spaces cleaner, more comfortable for users, and support the development of technology-based waste management solutions in Yogyakarta City.

Abstract

This study aims to redesign the production facility layout at PT. MMP in order to improve material flow efficiency and reduce material handling costs. The methods applied in this research are Activity Relationship Chart (ARC), From-To Chart (FTC), and Blocplan. Data were collected through direct observation, interviews, and documentation related to production processes, inter-department distances, and material movement frequencies. The results indicate that the existing layout is inefficient due to long material transfer distances. By redesigning the layout using the Blocplan method, a more optimal facility arrangement was obtained with reduced travel distances and improved production flow. The material handling cost analysis shows a decrease from Rp177,000 in the ARC layout to Rp64,000 in the Blocplan layout. Therefore, the Blocplan method is proven to be more effective in improving facility layout efficiency and reducing operational costs.
