Abstract

KKN is a form of student activity that involves serving the community. The purpose of this service activity is to socialize the creation of a waste bank by increasing public awareness of the importance of not littering. In addition, the waste bank is useful for all the people of Lubuk Dalam Village so they don't throw garbage or burn garbage, because from the garbage they can make money, crafts, etc., so they can boost the economy of the people in Lubuk Dalam Village. The method of implementing the activities was carried out through outreach to several schools and organizations in Lubuk Dalam Village. Through the "BERKAH" waste bank socialization activity in Lubuk Dalam Village, the community can also find out how to manage waste into goods of economic value. Garbage, which has been seen as trash by the general public, is something that causes an unpleasant, dirty, and disgusting smell. But with the existence of socialization activities regarding waste management, the smelly and dirty waste, if managed properly, can have economic value, as is currently being carried out by one of the waste banks, namely the "BERKAH" Waste Bank in Lubuk Village

Abstract

Riau Province has three main rivers: the Kampar, Rokan, and Siak Rivers, which play important roles in water transportation and infrastructure development. River water environments can accelerate the corrosion of metallic materials, including galvanized steel. This study aims to analyze and compare the corrosion rates of galvanized steel in the water media of the three rivers using the weight loss method based on the ASTM G31 standard. The experiments were conducted with immersion time variations of 168, 336, 504, and 672 hours. The observed parameters included mass loss, pH changes, and specimen surface morphology. The results showed that the highest corrosion rate occurred in Kampar River water, reaching 55.888 mpy after 672 hours of immersion, while the lowest corrosion rate was found in Rokan River water at 1.0052 mpy after 168 hours. The chemical characteristics of river water significantly affect the corrosion resistance of galvanized steel.
