Abstract

In today’s digital era, physics education demands more contextual and technology-integrated approaches to bridge abstract concepts with real-world experiences. This study aims to develop an innovative approach in physics learning by utilizing smartphone sensors to analyze the vertical motion dynamics of an elevator based on Newton’s Laws. The experiment was conducted in a five-story elevator at BRIDA Surakarta using the Phyphox application, which employs the smartphone’s built-in accelerometer and barometer. The modes "acceleration without g" and "elevator" were used to record real-time data of acceleration, velocity, and altitude. Data was collected through ten trials—five upward and five downward motion cycles. The recorded data revealed maximum acceleration values of ±8 m/s², aligning with the typical operational range of elevators (6–10 m/s²), while the altitude change was approximately ±18 meters, corresponding to the actual height of the building. The elevator’s motion was clearly segmented into three phases: initial acceleration, constant velocity, and deceleration. In each phase, passengers experienced distinct physical sensations—from feeling pressed down, to normal, to weightless—which closely correlated with the recorded acceleration data. These findings strongly validate the application of Newton’s Laws in non-inertial systems and the alignment between subjective sensations and quantitative measurements. Beyond reinforcing conceptual understanding through firsthand experience, this approach encourages active student engagement and enables experimentation without reliance on conventional physics laboratories. The study affirms that smartphone-based technologies hold great potential in democratizing access to scientific instrumentation and enhancing the quality of STEM education in a contextual, inclusive, and applicable manner.

Abstract

Pembelajaran materi energi alternatif ramah lingkungan di SMP masih sering bersifat teoritis sehingga siswa kurang memahami konsep transformasi energi dan penerapannya dalam kehidupan sehari-hari. Penelitian ini bertujuan mengembangkan kompor lipat berbahan bakar oli sebagai media pembelajaran fisika SMP pada materi energi alternatif ramah lingkungan serta menilai kelayakan, kepraktisan, dan keefektifannya. Metode penelitian yang digunakan adalah penelitian dan pengembangan (research and development/R&D) dengan model 4D yang meliputi tahap Define, Design, Develop, dan Disseminate. Penelitian dilaksanakan di SMP Muhammadiyah Program Khusus Kottabarat Surakarta. Subjek penelitian terdiri atas 30 siswa pada uji coba terbatas dan 32 siswa pada uji coba lapangan. Instrumen yang digunakan meliputi lembar validasi ahli materi, ahli media, dan ahli keselamatan; angket respons guru dan siswa; serta tes hasil belajar (pretest–posttest) pada materi energi alternatif. Data dianalisis secara deskriptif kuantitatif dengan menghitung skor kelayakan, kepraktisan, dan peningkatan hasil belajar menggunakan N-gain. Hasil validasi ahli menunjukkan skor rata-rata 3,58 (kategori sangat layak). Rata-rata respons guru dan siswa berada pada rentang 3,42–3,75 (kategori praktis–sangat praktis). Rata-rata skor hasil belajar meningkat dari 48,13 (pretest) menjadi 80,31 (posttest) dengan nilai N-gain 0,62 (kategori sedang), sehingga penggunaan kompor lipat berbahan bakar oli efektif meningkatkan pemahaman siswa tentang energi alternatif dan transformasi energi. Media ini juga berpotensi menumbuhkan ketertarikan dan kepedulian siswa terhadap pemanfaatan energi alternatif ramah lingkungan melalui kegiatan eksperimen yang kontekstual.
