Abstract/Executive Summary

This study aimed to develop and evaluate a universal motorcycle exhaust filtration prototype utilizing banana pseudo-stem fiber (Musa spp.) and coconut shell (Cocos nucifera)–derived activated carbon as sustainable and biodegradable materials. A quasi-experimental pretest–posttest design was employed to compare carbon monoxide (CO) and hydrocarbon (HC) emissions before and after the installation of the prototype. Emission testing was conducted at an authorized facility using a certified gas analyzer to ensure accuracy and reliability of results. Findings revealed a substantial reduction in CO emissions, from 6.595% to 2.21%, indicating a statistically significant decrease based on the Wilcoxon signed-rank test (p < 0.05). Hydrocarbon emissions also decreased from 767.5 ppm to 342.5 ppm, indicating a considerable reduction; however, the change was not statistically significant (p > 0.05), suggesting that while the decrease is meaningful in magnitude, it is not yet sufficient to confirm a consistent effect under the conditions of the study. Overall, the study demonstrates that agricultural waste materials can be utilized to develop an eco-friendly and functional exhaust filtration system that contributes to improved air quality and promotes sustainable environmental practices.
