Track: Senior Capstone Design Competition / FYP Competition

Abstract

This project aims to fabricate a scale model prototype of a machine that will serve as a waste collector and compactor for solid wastes that can efficiently prevent floods and preserve cleanliness. It will be an additional solution to reduce manual cleaning and the conventional use of nets to trap floating solid waste, which is unsafe for workers collecting garbage in canals. The proponents have considered different factors and options to determine the best possible features and the most feasible and reasonable design option. Trade-off analyses such as Technique for Order Preference by Similarity to Ideal Solution (TOPIS) using Entropy and CRITIC (The Criteria Importance Through Intercriteria Correlation) and sensitivity analysis were also used to determine the best design option. Among all the 18 design options considered by the proponents, the fabricated prototype was based on Design Option 11 with Closeness Coefficients (Ci) of 0.75 (Entropy) and 0.66 (CRITIC). It utilized mild steel as the body frame material, the semi-automated mechanism, and an electric linear actuator compactor system. This design project has accomplished the set objectives through testing, iterations, and statistical analyses. Furthermore, recommendations regarding the project's future improvements were provided, especially on its functions and features. These recommendations' main objective is to enhance the product's performance, durability, space utilization, holistic functionality, and lifespan.
