This paper analyzes the exhaust emission, noise, and performance of 110cc motorcycles experimentally through PCCS exhausts compared to standard exhausts. This study adopts an experimental method involving three tests: exhaust emission testing based on the SNI 09-7118.1-2005 standard, noise measurement using the static test procedure according to the UN-R 41-04 standard, and performance evaluation conducted with an inertial dynamometer. Implementing the PCCS exhaust system on a 110 cc automatic motorcycle positively impacts exhaust emissions, noise levels, and engine performance. Compared to the standard exhaust, the PCCS significantly reduces CO and HC emissions by 78.99% and 55.99%, respectively, while maintaining noise levels within regulatory limits in urban conditions. In terms of performance, the PCCS delivers higher torque and power output, particularly in the 3500–5500 RPM range, which aligns with typical riding conditions. These improvements are attributed to the system’s efficient exhaust flow and reduced backpressure. The PCCS exhaust presents a promising solution for enhancing environmental sustainability, performance, and rider comfort in small-displacement motorcycles.

Sustainable development programs in community life can enhance the welfare of the people in Malang City, especially in Rukun Warga 10, Tanjungrejo Village. Applying the community-based economic empowerment model sustainably can yield a significant positive impact. This research aims to illustrate how to manage used cooking oil waste as a community-based initiative that benefits both the economy and the environment. The focus of this research is the Kios Berkat Jelantah (Betah) Gempol Marga Bakti (Gemati) program, with an emphasis on descriptive data analysis. The results show that active collaboration between various parties, such as local communities, village officials, and educational institutions, encourages community participation in collecting and processing the used cooking oil into value-added products like soap and candles. This program has a positive impact on environmental preservation and provides new economic opportunities for local residents.
