Development of a responsive light-based electronic punching bag as a training medium for karate punches and kicks.

Perkembangan teknologi dalam bidang olahraga mendorong adanya inovasi media latihan yang lebih modern dan interaktif, termasuk pada cabang olahraga beladiri karate. Proses latihan pukulan dan tendangan pada karate umumnya masih menggunakan media konvensional sehingga diperlukan alat latihan yang mampu meningkatkan fokus, kecepatan reaksi, dan ketepatan gerak atlet. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan samsak elektronik berbasis lampu responsif sebagai media latihan pukulan dan tendangan beladiri karate yang layak digunakan dalam proses latihan. Penelitian ini menggunakan metode   (R&D) dengan model pengembangan 4D yang meliputi tahap define, design, develop, dan disseminate. Teknik pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi, serta angket penilaian. Analisis data menggunakan validitas Aiken’s V dan persentase kelayakan produk. Hasil penelitian menunjukkan bahwa samsak elektronik berbasis lampu responsif memperoleh nilai validitas Aiken’s V antara 0,75–1,00 dengan kategori valid. Pada uji coba skala kecil diperoleh persentase sebesar 89% dengan kategori sangat baik, sedangkan pada uji coba skala besar memperoleh persentase sebesar 91% dengan kategori sangat baik. Hasil tersebut menunjukkan bahwa produk dinyatakan layak digunakan sebagai media latihan pukulan dan tendangan beladiri karate. Berdasarkan hasil penelitian dapat disimpulkan bahwa samsak elektronik berbasis lampu responsif mampu menjadi media latihan yang inovatif, interaktif, dan modern untuk membantu meningkatkan fokus, kecepatan reaksi, serta ketepatan pukulan dan tendangan atlet karate.

The advancement of technology in sports has encouraged the development of more modern and interactive training media, including in the martial art of karate. Karate striking and kicking exercises are generally still conducted using conventional training equipment, creating a need for training media that can improve athletes’ focus, reaction speed, and movement accuracy. Therefore, this study aimed to develop a responsive light-based electronic punching bag as a training medium for karate strikes and kicks that is feasible for use in training sessions. This study employed a Research and Development (R&D) method using the 4D development model, consisting of the Define, Design, Develop, and Disseminate stages. Data were collected through observations, interviews, documentation, and assessment questionnaires. Data analysis was conducted using Aiken’s V validity test and product feasibility percentage analysis.

The results showed that the responsive light-based electronic punching bag achieved Aiken’s V validity scores ranging from 0.75 to 1.00, indicating that the product was valid. The small-scale trial obtained a feasibility percentage of 89%, categorized as very good, while the large-scale trial achieved 91%, also categorized as very good. These findings indicate that the product is feasible for use as a training medium for karate strikes and kicks.

Based on the results, it can be concluded that the responsive light-based electronic punching bag is an innovative, interactive, and modern training medium that can help improve the focus, reaction speed, and accuracy of karate athletes’ strikes and kicks.
