Abstract

Increased population growth is the main cause of increased waste in the environment, especially in water. Increased population growth is the main cause of increased waste in the environment, especially in water. Ammonia, nitrite, and nitrate are forms of inorganic nitrogen, which if they exceed water quality standards, can pollute the environment and are toxic to aquatic biota. However, the toxicity of nitrogen compounds in water can be controlled by microorganisms through nitrification and denitrification processes. In this study, two types of bacteria were used as biological agents in the bioremediation process, Pseudomonas aeruginosa and Bacillus subtilis, which grown anaerobically in media that has been added by KNO3 as a pollutant for 8 days. The results obtained showed that B. subtilis survived for 7 days before entering the cell death phase on the 8th day, while Pseudomonas aeruginosa survived for 5 days and entered the cell death phase on the 6th day. Meanwhile, based on its ability to reduce nitrate, B. subtilis can reduce it up to 99.42%, while P. aeruginosa can reduce it up to 98.26% in 8 days.

Abstract

The problem of failure to thrive in children due to insufficient nutritional intake over a verylong period of time will cause a problem known as stunting. The problem of stunting is a chronicproblem that has become a concern for the Indonesian government. Socialization to provideinformation to the community, especially in Sanding Village, Petir District, Serang-Banten, isneeded in efforts to prevent stunting. It is hoped that with socialization, the community, especiallythose who become parents, can increase their role in monitoring the growth and development oftheir children. This community service activity was carried out in Sanding Village, Petir District,Serang Banten in February 2023 by giving questionnaires (pre-test and post-test) to thecommunity who were participants in the socialization. Participants who attended were 88%housewives with 44% of the most dominant education being junior high school, and 74% fathersworking as laborers with 60% having high school education. During the socialization, 19 (68%)of the participants who came knew what stunting was, but after the socialization, 27 (96%) almostall participants already understood what stunting was. The results of the questionnaire alsoprovided information that the 28 people who attended the socialization activity alreadyunderstood the causes and efforts to prevent stunting.
