Abstract

Pesawat Atwood merupakan alat klasik yang digunakan untuk memverifikasi hukum gerak Newton. Fenomena gerak lurus beraturan (GLB) terjadi saat massa seimbang dan percepatan bernilai nol, sementara gerak lurus berubah beraturan (GLBB) muncul akibat perbedaan massa yang menghasilkan percepatan konstan. Penelitian ini mengimplementasikan transformasi digital melalui integrasi sensor inframerah (IR-LED), mikrokontroler Arduino Uno, dan otomatisasi pengolahan data berbasis Python. Sistem yang dikembangkan memiliki kemampuan untuk merekam interval waktu secara real time dengan kecepatan sampling 500 Hz, yang memungkinkan perhitungan percepatan dan kecepatan yang sangat akurat. Metode penelitian ini menggunakan pendekatan Research and Development (R&D) dengan hasil pengukuran menunjukkan bahwa sistem digital memberikan nilai error relatif lebih rendah dibanding metode manual. Salah satu manfaat utama penelitian ini adalah meningkatkan akurasi verifikasi hukum gerak Newton dan mendukung pengembangan instrumen pengukuran berbasis digital dalam pendidikan sains. Selain itu, temuan penelitian ini dapat digunakan sebagai dasar untuk penelitian tambahan tentang otomatisasi eksperimen fisika.

Abstract

Risky play presents a paradox in early childhood education (ECE): while it offers significant benefits for children’s growth and development, it raises concerns among parents and teachers. This study aims to explore the perceptions of parents and educators regarding risky play in early childhood. A survey approach was employed using a mixed-methods concurrent embedded design, combining quantitative and qualitative descriptive analyses. The study involved 112 participants, comprising early childhood education teachers and parents in Java. Data were collected through questionnaires and interviews to gather insights into parental knowledge about risky play, the types of risky play, their concerns, and their expectations. Quantitative findings revealed that 77% of parents are familiar with risky play, while 30% are not. Parents expressed the highest concern for water-related activities (90.9%), followed by sliding activities (88.4%). Injuries were identified as a significant concern, with 56.6% worried about physical harm and 14.8% about peer influence. Additionally, parents and teachers highlighted the importance of receiving information on risk management in risky play. The findings of this study can inform the development of risk management programs tailored for early childhood education, ensuring a balance between developmental benefits and safety considerations
