Abstract

This community service discusses the importance of introducing science and technology to students at primary school age. The age range of primary school students is between seven and twelve years old, where children's development is continuous. During this time, students begin to recognise new objects around them and explore the world with natural curiosity. Children's talents develop in various aspects, including religious and moral beliefs, physical-motor, cognitive, verbal, social-emotional, and artistic abilities. the sample in this community service is elementary school students of Molotabu Village.  The survey results showed that as many as 78% of primary school students were able to identify the pictures that constitute science and technology, demonstrating their understanding of these basic concepts. Next, students are engaged in simple experiments using materials that are easily found around them. These experiments aim to give students hands-on experience in testing their hypotheses or ideas about how things work. In the simple experiment, about 60% of the students managed to carry it out well.

Abstract

Water sampling skills are essential competencies for chemistry students because the accuracy of sampling procedures determines the representativeness and reliability of water quality analysis data. However, students still have limited understanding of sampling-point selection, the use of sampling equipment and containers, labeling, preservation, and field measurement of water quality parameters. This community service activity aimed to strengthen students’ competence in water sampling through a learning-by-doing approach. The program employed educational and training methods, including theoretical instruction, equipment demonstrations, field practice, discussion, and evaluation using pretest and posttest instruments. The evaluation covered four indicators: basic principles of water quality and monitoring, sampling-point selection and procedures, equipment use, labeling and sample preservation, and measurement of pH, temperature, turbidity, and dissolved oxygen. The evaluation results showed that the students’ average understanding increased from 58.75% before the training to 84.00% after the training, representing an increase of 25.25%. The highest improvement was found in equipment use, labeling, and sample preservation, with an increase of 27%. Descriptively, these findings indicate that the learning-by-doing approach strengthened students’ understanding and practical skills in water sampling and handling. Similar training should be continued through periodic practice and the development of a student-based water quality monitoring group.
