"Physics Spring Fun": Implementasi Kit Alat Peraga Elastisitas Pegas untuk Meningkatkan Pemahaman Konsep Fisika Siswa di SMK Sasmita Jaya 2, Pamulang Barat, Tangerang Selatan

Abstract

Kegiatan Physics Spring Fun merupakan program Pengabdian kepada Masyarakat (PkM) yang bertujuan meningkatkan pemahaman konseptual siswa terhadap elastisitas pegas dan Hukum Hooke melalui pembelajaran berbasis eksperimen menggunakan kit alat peraga. Kegiatan dilaksanakan di SMK Sasmita Jaya 2, Pamulang Barat, Tangerang Selatan, sebagai respons terhadap kondisi pembelajaran fisika yang masih dominan teoritis dan terbatas dalam pemanfaatan kegiatan praktikum. Metode pelaksanaan menerapkan pendekatan experiential learning dan student-centered learning melalui tahapan pretest, penyampaian konsep, demonstrasi dan praktikum menggunakan kit, serta posttest. Selama praktikum, siswa terlibat langsung dalam pengamatan, pengukuran gaya dan pertambahan panjang pegas, pengolahan data, analisis hubungan antarvariabel, dan penarikan kesimpulan berdasarkan Hukum Hooke. Hasil evaluasi menunjukkan adanya peningkatan pemahaman konsep siswa, ditunjukkan oleh kenaikan rata-rata nilai dari 46,96 pada pretest menjadi 64,78 pada posttest, atau meningkat sebesar 38%. Selain peningkatan hasil belajar, kegiatan memberikan pengalaman empiris yang mendukung pengembangan keterampilan proses sains, kemampuan berpikir analitis, serta sikap ilmiah siswa. Hasil tersebut menunjukkan bahwa penggunaan kit alat peraga elastisitas pegas efektif sebagai media pembelajaran kontekstual yang menghubungkan konsep teoritis dengan fenomena fisik melalui pengalaman eksperimen langsung. Program ini diharapkan dapat menjadi alternatif inovatif dalam penguatan pembelajaran fisika yang interaktif, aplikatif, dan berbasis inkuiri di tingkat SMK.

ABSTRACT

Physics Spring Fun is a community service program designed to improve students’ conceptual understanding of spring elasticity and Hooke’s Law through experiment-based learning using an instructional spring elasticity kit. The program was conducted at SMK Sasmita Jaya 2, Pamulang Barat, South Tangerang, in response to physics instruction that remains predominantly theoretical and provides limited opportunities for practical experimentation. The implementation adopted experiential learning and student-centered learning approaches through a series of activities consisting of a pretest, conceptual instruction, demonstration and hands-on experimentation using the kit, and a posttest. During the practical activities, students were directly engaged in observing spring behavior, measuring applied force and spring elongation, processing experimental data, analyzing relationships among variables, and drawing conclusions based on Hooke’s Law. The evaluation results indicated an improvement in students’ conceptual understanding, as reflected by an increase in the mean score from 46.96 on the pretest to 64.78 on the posttest, representing a 38% improvement. In addition to improving learning outcomes, the program provided empirical learning experiences that supported the development of students’ science process skills, analytical thinking abilities, and scientific attitudes. These findings demonstrate that the use of a spring elasticity instructional kit can serve as an effective contextual learning medium that connects theoretical concepts with physical phenomena through direct experimental experience. The program is expected to provide an innovative alternative for strengthening interactive, applicable, and inquiry-based physics learning at the vocational high school level.
