Abstract

Fenomena difraksi dapat terjadi pada biomaterial misalnya terjadi pada pewarnaan bagian tubuh hewan tertentu (natural coloration). Penelitian ini bertujuan untuk menunjukkan fenomena difraksi yang melibatkan rambut sebagai biomaterial dan menentukan diameter rambut menggunakan konsep difraksi. Penelitian ini menggunakan rambut sebagai penghalang (obstacle) dan LASER merah. Hasil penelitian menunjukkan bahwa fenomena difraksi dapat dihasilkan dengan menggunakan LASER dan rambut. Sementara itu, hasil pengukuran diameter terhadap sampel rambut yaitu berkisar pada 6×10-5m sampai 18×10-5 m.  Penelitian ini menunjukkan bahwa pola difraksi dapat dibentuk dengan peralatan sederhana dan konsep difraksi dapat dimanfaatkan untuk melakukan pengukuran tak langsung.

Abstract

The accelerating development of digital technology has shaped a rapidly evolving information landscape, significantly impacting the realm of education. The integration of digital technology in education necessitates a positive outlook and a strong digital literacy. The research adopts a Research and Development (R&D) approach and employs the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model for development. Data collection tools in this study include observation sheets, expert validation sheets, student response questionnaires, and digital literacy tests. The data analysis combines qualitative and quantitative techniques, including a t-test. The findings of this research indicate that the utilization of e-modules based on CPS only succeeded in enhancing the indicators of communication skills through digital media and the responsible and positive use of digital media, among all the digital literacy indicators.
