Abstract

Fraktur adalah patah tulang yang disebabkan oleh trauma atau tenaga fisik. Permasalahan fraktur dapat menjadi besar jika tidak ditangani dengan baik. Untuk itu penyembuhan fraktur menggunakan Pulsed Electromagnetic Field (PEMF) menjadi salah satu solusi. Penelitian ini bertujuan merancang alat terapi fraktur berbasis medan elektromagnetik. Alat terapi fraktur yang dibuat menggunakan kumparan Helmholtz untuk menghasilkan medan magnet dengan variasi jumlah lilitan kawat 50 – 400 lilitan, variasi kuat arus 0,12 – 0,19 A, variasi jarak antara kumparan 5 – 25 cm, dan variasi diameter 19,8 cm dan 22 cm. Berdasarkan data yang diperoleh dapat membuktikan bahwa medan magnet berbanding lurus dengan arus dan jumlah lilitan namun berbanding terbalik terhadap jarak antara kumparan dan besar diameter kumparan. Hasil penelitian menunjukan bahwa nilai medan magnet 150 µT berhasil diperoleh dengan nilai arus 0,15 A, jumlah lilitan kawat sebanyak 300, jarak antara kumparan 10 cm, dan diameter kumparan helmholtz 19,8 cm.

Abstract

This study aims to discover: 1) the results of the development of Smartphone-based interactive e-modele in Fabric Decorating Techniques Courses to improve the learning outcomes in PKK Department FT UNM, 2) whether the feasibility of the smartphone-based interactive e-modele learning media developed meets valid criteria, 3) whether the feasibility of smartphone-based interactive e-modele learning media developed meets practical criteria, 4) whether the feasibility of the smartphone-based interactive e-modelelearning media developed meets effective criteria. The method used in this study is Research and Development (R&D). The research subjects were 32 students and 2 lecturers in PKK Department FT UNM. Data collection techniques used were tests, questionnaires, and e-modele validation. The module development process employed the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) e-development model. The analysis phase includes an analysis of the needs for learning resources, curriculum, and materials. The design stage includes creating the e-modele framework, determining the layout and reference book, and preparing the e-modele assessment instrument. The development stage includes e-modele development, expert validation and e-modele revision. The implementation stage is the trial stage of the e-modele, which had been validated and revised for students. The evaluation stage is the stage of analyzing the strengths and weaknesses of the e-modele that had been tested. The quality of the module is determined by three criteria: validity, practicality, and effectiveness. This e-modele is declared as valid based on an assessment from the material expert with an average of 87% (very valid) and an assessment from the media expert with an average of 91% (very valid). Moreover, the e-modele is declared as practical for use by students based on the results of the students’ response questionnaire with an average of 83% (Very practical). Furthermore, based on the test results before and after using the e-modele, it is declared as effective for use by students based on the results of the pretest and p osttest with an average score of 71% (effective).
