Abstract

The application of teaching materials and teaching resources in learning is appropriate and needs to be paid attention to. The research carried out aims to develop a student worksheet (LKPD) based on scientific literacy on the sub-material of environmental pollution with the topic of water pollution which can increase students' understanding of environmental pollution. This research uses research and development (R&D) methods with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). LKPD testing was carried out at SMP Negeri 01 Raja Ampat in grade seven involving 12 students. Based on the research findings, data analysis was carried out with results of 96.43% from material experts and 85.83% from media experts and fulfilling the very feasible category. For the regarding the results of the effectiveness test, student learning outcomes were found to be in the high category with a value of n ≥ 0.7. Meanwhile, the results of the practicality test through student responses showed that 12 students were positively interested in using LKPD in terms of scientific knowledge with a percentage result of 95%. Therefore, it can be concluded that LKPD can be used in learning.

Abstract

Smartphone integration for high school students has significant potential in physics learning. This research aims to analyze smartphone sensor data in the context of physics experiments carried out at traveling carnivals. This research uses experimental methods to compare smartphone sensor data collected via the Phyphox application with video analysis data obtained using Tracker software. The research results show the effectiveness of smartphone sensors in several carnival games, including simple leg swings, bicycle spins, kora-kora vehicles, and merry-go-rounds. Smartphone sensors can show graphs of simple harmonic motion, angular velocity, and centripetal acceleration on the game vehicle. However, limitations arise in the case of Ferris wheels and mini Ferris wheels, where smartphone sensors show reduced effectiveness caused by the instability of passenger seats during the ride. This research suggests avenues for further exploration by computing physical quantity values derived from smartphone sensor data, offering insights into potential improvements and applications in dynamic environments such as theme parks.
