Abstract

This study aims to develop an interactive digital module based on STEM by utilizing the Canva and Heyzine Flipbooks platforms as supporting media. The benefits of this study are to contribute to the development of STEM-based learning concepts, especially in renewable energy materials. This research was conducted at SMA Negeri 59 Jakarta in the even semester of 2025. This research method used Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The results of this study indicate that the developed product is declared very feasible to use, with an assessment from media experts of 89% (very feasible), material experts 86% (very feasible), and learning experts 96% (very feasible). The product trial results also showed a high level of feasibility, namely 96% (very good) from teachers and 85% (very good) from students. Thus, the interactive digital module based on STEM on renewable energy material is suitable for use as a physics teaching material in high school.

Abstract

This research aims to develop a digital module based on the Meaningful Learning approach to enhance high school students’ critical thinking skills in two-dimensional kinematics as self-paced learning material that supports 21st-century learning demands. The study employed a Research and Development (R&D) method using the Dick and Carey model. The product developed is an interactive digital module containing contextual and meaningful learning activities designed to improve students’ critical thinking skills. Expert validation results showed that the module was highly feasible, with scores of 86.3% for the media aspect, 95.83% for the content aspect, and 96.3% for the learning aspect. Limited trials involving 28 students obtained a positive response rate of 95.13%, while trials involving two educators resulted in a score of 93%, both categorized as strongly agree. Preliminary findings from the use of the digital module indicate an improvement in students’ critical thinking skills, as evidenced by an increase in the average pretest score from 57.62 to 74.52 on the posttest, with an n-gain score of 0.43 categorized as medium. Therefore, the developed digital module is strongly feasible as self-paced instructional material for fostering students’ critical thinking skills through meaningful learning experiences.

Abstract

Elektroda pensil grafit tipe B memiliki karakteristik dapat menghantarkan listrik lebih mudah dibandingkan tipe F dan H. Pada penelitian ini akan dikaji dan dianalisis sifat dasar dari konduktivitas listrik beberapa variasi pensil grafit tipe B, dianmtaranya B, 2B, 4B, 6B dan 8B. Penelitian ini menggunakan pendekatan kurva karakteristik arus-tegangan yang dimodelkan melalui pencocokan persamaan garis lurus untuk mendapatkan komponen 1/R yang digunakan dalam penentuan konduktivitas listrik sampel uji melalui hukum ohm. Pengukuran konduktivitas listrik dilakukan dengan memasukkan dimensi dari bahan berupa diameter dan panjang sampel uji menggunakan jangka sorong. Hasil penelitian menunjukkan bahwa konduktivitas listrik pada elektroda pensil grafit tipe 8B memiliki konduktivitas listrik yang terbaik diantara seluruh sampel uji yaitu 341.94 S/m. Penelitan ini menunjukkan bahwa semakin tinggi ukuran nomor pada elektroda pensil tipe B, semakin baik konduktivitas listriknya sehingga bahan elektroda tersebut mudah menghantarkan listrik. Ukuran nomor dan tipe yang terdapat pada elektroda pensil grafit menunjukkan konsentrasi grafit yang terdapat pada bahan tersebut sehingga semakin besar nomor pada tipe pensil grafit tipe B maka kandungan grafit akan semakin banyak yang menyebabkan sifat konduktivitas listrik dari bahan pensil semakin meningkat
