Abstract

The large amount of liquid waste generated from urban activities can provide negative impacts, such as disease spread, environmental damage, and others. Therefore, treatment efforts before disposal into the environmental are crucial. One method of treating liquid waste that can be used is the trickling filter. The trickling filter method used in this research utilizes natural fibers, namely coconut fiber, as the packing media, replacing sand or plastic as the packing media in conventional trickling filters. Treatment of municipal liquid waste (domestic waste) using coconut fiber trickling filters is one application of biofilm technology in wastewater treatment, where a biological layer (biofilm) like mucus will grow on the surface of the media. This biological layer will meet the wastewater and degrade the pollutant compounds presentin the wastewater, resulting in water with lower biological oxygen demand (BOD) values than before. Theresult if water that is safe for disposal into the environment. This trickling filter reactor can degrade pollutants with degradation efficiency of BOD 91.3%, nitrate 50.25%, and ammonia 37.5% at the optimal flow rate of this study (0.256 L/min).

Abstract

This community service activity is aimed at increasing face-to-face (offline) student practice and knowledge about the practice of preventing post-Covid 19 symptoms. The activity was held at the 69 State Elementary School (SDN) in Gampong Kopelma Darussalam Banda Aceh. The target of this socialization activity is students who spend most of their time playing and studying. The students of SDN 69 are mostly a group of sixth grade students. This service activity began with communication with the teachers at SDN 69 to agree on a time for socialization. Furthermore, at the meeting, brochures were also distributed containing information about the materials needed for the process of making hand sanitizers, manufacturing procedures, theoretical basis, and tricks in making hand sanitizers. Direct practice is carried out with demonstrations of the manufacturing process to finished products accompanied by direct discussions with students. This activity has been able to increase knowledge, insight, and can also improve students' attitudes in Gampong Kopelma Darussalam Banda Aceh, so that it has the opportunity to inhibit the spread and transmission of post-Covid 19 symptoms in Banda Aceh.
