Abstract

The low level of scientific literacy in Indonesia has prompted efforts to improve the quality of science education, particularly through the promotion of science process skills. Practical activities such as experiments and hands-on investigations are indicators of science skill–based learning. However, their implementation is often limited by the lack of adequate laboratory equipment. This study introduces a simple, low-cost experimental kit designed to facilitate the teaching of heat and its transfer processes, specifically for the senior high school level. The study describes the kit construction, provides conceptual explanations of the underlying physics, and examines student participation during learning activities conducted with the Discovery Learning model. A case study approach was employed, with qualitative data collected through classroom observations and informal interviews. The findings indicate that students actively engaged throughout the learning process, from assembling the kit to conducting group experiments. They were able to directly observe heat transfer phenomena through conduction, convection, and radiation. This hands-on experience enhanced their conceptual understanding, as reflected in their ability to confidently explain experimental results during class discussions. The study concludes that the Simple Heat Transfer Kit can serve as an effective alternative medium for teachers to implement science skill–based learning, thereby improving both student participation and conceptual comprehension, particularly on the topic of heat transfer.

Abstract

Renewable Energy based Hands-on experimental kits are essential for enhancing student engagement and conceptual understanding in physics education. This study evaluates the feasibility of a Solar-Powered Direct Current (SP-DC) experimental kit, focusing on its effectiveness, relevance, and endurance as perceived by users. A quantitative design was employed using a closed-ended questionnaire comprising 14 items. Participants (n=79) consisted of undergraduate students from Universitas Kristen Indonesia (n=36) and high school students from SMA N 11 Jakarta (n=43). Prior to completing the questionnaire, students engaged in assembling the SP-DC kit and measuring current and voltage. Data were collected between June 2022 and June 2023 and analyzed using the Rasch model through Winstep version 5.9.00. Fit validity was determined by item and person statistics (MNSQ, ZSTD, PTMEA), while descriptive analysis included item measures and score distributions. Findings confirmed that all questionnaire items met Rasch model validity criteria, with PTMEA correlations above 0.7. In terms of effectiveness, participants reported favorable perceptions of ease of use and assembly, though aspects such as portability and storage required improvement. Relevance was demonstrated through the kit’s role in supporting understanding of series and parallel circuits, motivating interest in renewable energy, and strengthening connections between theory and practice. Endurance analysis revealed that the kit was generally durable and safe, though operational robustness could be enhanced. The SP-DC experimental kit is a feasible educational tool that supports effectiveness, curricular relevance, and endurance. These results suggest the kit’s potential for broader application in both secondary and higher education.

Abstract

Statistical mechanics is the study of physics that relates macroscopic and microscopic parameters, often studied only with a theoretical approach, so it is relatively difficult to understand.  For this reason, simple practical activities are needed to be connected with statistical mechanics, one of which is a viscosity experiment to determine the Boltzmann factor. This research was conducted to evaluate the viscosity value, coefficient of determination (R2), Reynolds number, activation energy and Boltzmann factor obtained from the experiment of dropping marbles in a tube containing cooking oil at a temperature variation of 303K-333K. Viscosity is calculated based on the observed terminal velocity of the ball using Stokes' Law. The magnitude of the activation energy is analyzed using the Arrhenius equation and the probability of fluid particles flowing was calculated using the Boltzmann factor. The results showed that the viscosity of cooking oil decreased with increasing temperature, with viscosity values ranging from 44-79 cP. The Reynolds number is evaluated in the range <2300 confirming laminar flow and suitable for Stokes' law. The activation energy of viscous flow was obtained as 11.489 kJ/mol with a coefficient of determination R² = 0.87712 which indicates a strong correlation between temperature and viscosity. The estimated number of moving particles based on the Boltzmann factor is evaluated to be 1.05% - 1.58%. This research validates that the hands-on approach can explain that the increase in kinetic energy of molecules at high temperatures reduces the viscosity of the fluid, thereby increasing the probability of fluid particles flowing.

Abstract

Indonesia sebagai salah satu negara dengan penduduk terpadat di dunia, menghadapi tantangan permintaan pasokan energi yang terus meningkat. Hal ini mendorong urgensi transisi energi fosil ke energi terbarukan, dimulai dengan penumbuhan kesadaran terhadap yang berkelanjutan. Sejalan dengan itu, program pengabdian kepada masyarakat (PKM) ini bertujuan untuk menumbuhkan kesadaran energi terbarukan pada siswa SMA. Keterbatasan alat peraga menjadi salah satu penyebab hambatan dalam penumbuhan kesadaran akan energi terbarukan, yang dikonfirmasi oleh hasil observasi awal di SMAN 19 Bekasi. Sebagai bentuk solusi dari permasalahan yang dialami, pada tanggal 21 Agustus 2025 Prodi Pendidikan Fisika FKIP UKI menyelenggarakan PKM berupa pelatihan perakitan dan pengoperasian kit panel surya mini di SMAN 19, yang terdiri dari kit aplikasi panel surya dan kereta panel surya. Peserta dalam PKM ini adalah 43 orang siswa kelas XII konsentrasi teknik. Evaluasi kegiatan dilakukan untuk mengetahui keberhasilan kegiatan, yang dilakukan melalui observasi keberhasilan peserta dalam merakit dan mengoperasikan kit panel surya, serta survei kepuasan peserta. Instrumen evaluasi berupa kuisioner dengan skala likert 1-5. Indikator yang digunakan untuk mengukur tumbuhnya kesadaran terhadap energi terbarukan yaitu: kesesuaian kegiatan PKM untuk meningkatkan wawasan dan keterampilan, ada dorongan minat terhadap teknologi energi terbarukan, serta tumbuh inspirasi secara pribadi untuk merakit teknologi terkait energi terbarukan. Hasil observasi menunjukkan bahwa seluruh kelompok (100%) berhasil merakit dan mengoperasikan kit panel surya. Sementara hasil survei menunjukkan masing-masing 78,33% siswa setuju bahwa kegiatan pelatihan mendorong minat dan memberi inspirasi merakit peralatan terkait energi terbarukan,serta  76,68% pelatihan menambah wawasan dan keterampilan. Lebih lanjut, program ini berpotensi berkelanjutan karena guru berkomitmen untuk menggunakannya dalam pembelajaran sains di masa mendatang. Model program ini berpotensi direplikasi di sekolah lain guna mendukung agenda nasional dalam meningkatkan literasi energi terbarukan.

Abstract

Statistical mechanics bridges macroscopic fluid properties with microscopic molecular dynamics, yet its experimental estimation remains a challenge in physics education. To overcome this learning obstacle, Boltzmann Factor estimation could be performed with a simple Hands-on approach, one of which is the viscosity of a falling ball. This study validates the falling ball thermo-viscosity method for estimating activation energy and Boltzmann Factor in the Francis wall-correction model to resolve the wall effect with narrow tube (λ = 0.69). It uniquely applies Federal Racing Matic SAE 10W-30 oil bridging macroscopic kinetics with statistical microscopic parameters. The experiment was conducted by dropping a marble into the fluid at a fixed distance with a temperature variation between 308 K – 328 K. Compensation for the wall effect of the tube was carried out through Francis correction. Reynolds number indicated deviation from Stokes’ regime, resulting in an apparent rather than true viscosity. From the plot of approximation viscosity vs invers temperature, Arrhenius Law extracted  value is 35.66 ± 6.35 kJ/mol. Meanwhile relative Boltzmann Factor were close to the industrial data. Pearson's r (0.97) and values of R2 (0.94) indicate high methodological validity. Despite geometric limitations causing ~25% deviation in viscosity, the temperature-dependent trend remains enabling accurate activation energy estimation and extraction of the relative Boltzmann factor. These results support the falling ball viscosity method as a simple alternative experimental approach for quantitatively visualizing the abstract theory of classical particle distributions.
