Abstract:
This project’s primary goal is to teach individuals about proper waste segregation. The incorrect sorting and disposal of garbage pose urgent problems, leading to contamination and inefficiencies in recycling operations. Innovative solutions supporting adequate waste segregation and disposal procedures are crucial to addressing these challenges. This study introduces an Arduino Uno-based sound sensor system to promote appropriate garbage disposal practices and enhance waste sorting efficiency. This method facilitates proper trash disposal by simplifying waste categorization into two types—metal and non-metal—and utilizing sound prompts. The study employed an applied experimental research design with four phases to develop and evaluate the product. Physical components, including cardboard, copper, and glue, were utilized alongside automation provided by an Arduino Uno R3, capacitive and inductive proximity sensors, a piezo buzzer, a servo motor, and wire. The researchers used essential software to configure the Arduino Uno to manage the system components. The evaluation included self-observation through trial and error and questionnaires from eight participants. Statistical analysis utilized the t-test for means and frequency distribution for descriptive analysis. Results indicate significant improvements in waste sorting convenience, particularly in public spaces, facilitated by the Arduino Uno-based sound sensor system. This study advances waste management technology by offering a practical approach to promoting appropriate trash disposal practices. The researchers’ findings suggest designing trash bins to accommodate a large volume of garbage efficiently. Increasing the bin size provides adequate capacity for waste collection, reduces the frequency of emptying, and improves overall convenience.
