Abstract
This community service activity aimed to provide an enjoyable science learning experience for junior high school students at MBS Tangerang Regency through training on making hand-cranked ice cream. The initiative was motivated by the importance of using concrete and engaging learning media to help students grasp science concepts relevant to daily life. The activity involved delivering information, conducting demonstrations, hands-on ice cream making, and evaluating the experience via questionnaires. Students were directly involved in every stage, from ingredient preparation and the production process to observing the physical changes that occurred. The results showed that the students participated enthusiastically and responded positively to the use of hand-cranked ice cream making as a learning medium. This practical activity helped students understand science concepts—specifically changes in the state of matter, heat transfer, and the freezing process—in a more concrete and contextual manner. The activity also encouraged students to actively observe, collaborate, follow procedures, and relate scientific concepts to their everyday lives. Thus, hand-cranked ice cream making serves as a simple, practical, interactive, and enjoyable alternative learning medium for junior high school science education.
