Abstract

This community service activity aims to internalize the values of Teuku Umar's struggle as an inspiration for students in achieving their dreams. This activity is based on the problems faced by traditional dayah, coupled with the existence of skeptical assumptions from the community that can affect the motivation and self-confidence of students. The approach used is a participatory educational approach by actively involving students and fostering good communication. This activity consists of two main sessions, namely interactive seminars and training on planning goals. The results of the study showed that the values of Teuku Umar's struggle could be internalized by students of Dayah Darul Faizin and also the building of students' self-confidence increased after the training, motivating them to continue fighting despite their limitations. This activity received a positive response from all participants, including teachers, and was considered useful in shaping the character of students.

Abstract

This study evaluated the effectiveness of coagulants and flocculants in improving clarifier water quality, with a focus on pH, iron (Fe) concentration, and turbidity levels. In accordance with Indonesia’s Ministry of Health Regulation No. 32/2017 on environmental health standards for water, clarifier water samples were analyzed before and after treatment. The results show that the treated water complied with the specified standards, with pH levels ranging from 6.5 to 8.5, Fe concentrations below 1 mg/L, and turbidity under 25 NTU. The application of aluminum sulfate as a coagulant and polymer as a flocculant effectively reduced Fe concentrations and turbidity while adjusting the pH to acceptable levels. These findings confirm the critical role of coagulation and flocculation in industrial water treatment processes and demonstrate their potential for enhancing water quality in clarifier systems.
