The effect of natural antibiotics Moringa oleifera seeds powder in cellulose acetate membranes as biofouling reducer agent was investigated. Mixed matrix membranes (MMM) were synthesized by adding 100 mesh M. oleifera seeds powder with variation of three concentrations (1 wt%, 2 wt%, and 3 wt%), into a mix polymer solution of CA (cellulose acetate) and two different solvents, i.e., DMF (dimethylformamide) and DMAc (dimethylacetamide). The synthesized membranes morphology was observed under scanning electron microscopy and from the images can be seen that the membranes made of DMAc formed rather large macrovoid as compared to DMF-based membranes. The microstructure affected the water flux through the membranes, in which the DMAc membranes provided a higher flux value and served as high-throughput microfiltration membranes. Antibacterial properties of MMM were tested using Escherichia coli adhesion onto membrane surfaces. The results showed that M. oleifera has been proven to eradicate E. coli activity on the membrane surfaces due to interaction between bacterial cells and phenolic compounds from M. oleifera, through absorption processes involving hydrogen bonds.

Food safety is an effort to prevent the possibility of products being contaminated by biological, chemical, and physical contaminants. Food contamination is undesirable for both producers and consumers. This contamination occurs in micro small enterprises such as canteens. This activity focuses on Kantin Pertama at the Faculty of Medicine, Mulawarman University. This Community Service Program aims to provide education about hygiene and sanitation to the MSME (Micro, Small, and Medium Enterprises) at Kantin Pertama. This will ensure better quality and safety of the food and beverages produced in Kantin Pertama. The Community Service Program is carried out from December 19, 2023, to January 31, 2024, using three methods: first, socialization and discussion; second, observation and interviews; and third, problem-solving with assistance. Observation and interviews are conducted to identify issues occurring in the First Canteen. Then, problem-solving is carried out through assistance. The project was progressing smoothly. After completing the Class A1 food service questionnaire, we obtained a total score 62. However, after implementing the solution, the total score increased to 66, meeting the score range of 65-70.

Food is a necessity for humans, yet cases of food poisoning and infectious diseases related to food continue to rise. Contributing factors include poor personal hygiene, inadequate food handling, and unclean equipment. Food vendors often lack educational backgrounds in hygiene and sanitation, which affects the quality of the dishes they serve. This community service initiative emphasizes the importance of implementing hygiene and sanitation practices in the Kopikir Ika canteen at Mulawarman University. The methods used include socialization, observation, and education for the canteen operators. The results show increased awareness and understanding of the operators regarding the importance of hygiene and sanitation, as well as the steps taken to improve cleanliness standards in the canteen and the quality of the food products served.
