Abstract

Development of atlases needs to be developed through teaching material based on local potential. This study aims to (1) Determine the steps for developing teaching materials atlas kingdom plantae morphology of mangrove plants based on local potential at PPLH Puntondo Takalar; and (2) Test the level of validity, practicality, and effectiveness of teaching materials atlas kingdom plantae morphology of mangrove plants based on potential at PPLH Puntondo Takalar. The ADDIE research model (Analysis, Design, Development, Implementation, and Evaluation). The development model is used in this type of research and development. Validity, practicality, and effectiveness are evaluated during the product development process. Twenty six (26) students of class XI IPA MA Muhammadiyah Salaka were used as research objects. Product validity is assessed using media validation sheets, practicality the product is assessed using responses from students and educators, and the effectiveness of the product is assessed. The level of data validity is 3.6, meaning it is very valid. The practicality level of the answer is 92%, which means it is very practical. the results of the research, the Magic Box teaching materials should be used because they meet the valid, useful, and effective requirements.

Abstract

In Basic Physics instruction, particularly in laboratory experiments involving direct current (DC) circuits, the need for accurate, real-time, and efficient power measurement tools is critical. Traditional instruments often fall short in delivering such performance, leading to errors and delays in data analysis. To address this issue, this study developed and implemented an Internet of Things (IoT)-based power measurement tool utilizing Arduino NodeMCU, capable of real-time data transmission and processing through Wi-Fi connectivity. The integration of current and voltage sensors enables more accurate and accessible DC power measurements for educational purposes.This research employed a quantitative approach using a one-group pretest-posttest quasi-experimental design. A total of 12 students enrolled in the Basic Physics Laboratory course participated in the study. The effectiveness of the tool was evaluated through pretest and posttest assessments, student response questionnaires, and observational data. Normality testing (Shapiro-Wilk) showed that both pretest (p = 0.262) and posttest (p = 0.284) scores were normally distributed. A paired sample t-test revealed a significant improvement in students’ conceptual understanding (t = -8.20, p = 5.14 × 10⁻⁶). The average normalized gain (N-Gain) score was 0.565, indicating a medium level of improvement, with 75% of students falling in the medium category and 25% in the high category. Student feedback also reflected a positive perception of the tool, with an average response score of 84.5 out of 100. These results suggest that the IoT-based measurement tool not only enhances the accuracy and efficiency of data collection in Basic Physics experiments but also improves students’ conceptual understanding and engagement. The innovation aligns with modern educational goals by integrating digital technology into science instruction, preparing students for real-world scientific and technological challenges.
