Aprilia Wulandari — 2026-05-04

This study aims to analyze the effectiveness of Game-Based Learning (GBL) using the Genially platform in enhancing students' collaboration skills in physics learning. The research employed a literature review method by examining 23 relevant articles published in national and international journals. The findings indicate that the use of digital educational games, particularly Genially, has a positive impact on students' learning outcomes, motivation, and collaboration skills. Interactive features such as animations, quizzes, and simulations encourage active student participation through communication, teamwork, and collaborative problem-solving activities. Furthermore, Genially supports the development of 21st-century skills by promoting social responsibility, cooperation, and teamwork. Therefore, the integration of Game-Based Learning through the Genially platform is not only effective in improving students' cognitive achievement but also plays a significant role in developing collaborative skills essential for modern education.

PERANCANGAN SIMULASI DIGITAL VAN DE GRAAFF BERBASIS WEB SEBAGAI MEDIA PRAKTIKUM LISTRIK STATIS

Abstract: This research aims to develop a digital simulation of the Van de Graaff Generator as an alternative medium for static electricity practicums while also developing a valid and suitable user guide for physics learning in schools. This development is driven by a research gap, namely the limited availability of physical Van de Graaff Generators in schools and the absence of digital simulations that specifically visualize typical phenomena such as hair standing on end or the movement of paper pieces, and the absence of local simulations that allow flexible adjustment of experimental variables according to curriculum needs. The simulation was designed through a virtual physics experiment using HTML, CSS, and JavaScript and then validated by comparing the results of calculations of electric potential, electric field, and Coulomb force at various distances with theory. The results show that the simulation works stably, interactively, and very accurately, with a 98% agreement level, and is able to display patterns of V, E, and F decreases that are consistent with Coulomb's Law, making it suitable as an alternative physical teaching aid in static electricity learning.

Abstract: This study aims to analyze the management system of medium-scale layer chicken farms, focusing on aspects of feed management, animal health, waste handling, and adaptation to environmental conditions. The research employed a qualitative descriptive approach through a case study and in-depth interviews with an independent farmer. The results showed that although modern technology was not applied, disciplined and adaptive farm management practices maintained a high egg productivity of around 700 eggs per day. The farmer implemented a feeding schedule three times a day, maintained cage hygiene, and regularly conducted vaccinations and preventive treatments. The main challenge was extreme temperatures causing chicken stress and reduced productivity, which was addressed by reducing cage density and increasing water supply frequency. Waste handling was carried out manually with disinfectant spraying to minimize odor and disease risk. In conclusion, medium-scale layer chicken farms have significant potential to support local food security if supported by proper training and appropriate low-cost technological innovations.

PENENTUAN NILAI KALOR JENIS LOGAM MENGGUNAKAN METODE KALORIMETER BERDASARKAN ASAS BLACK

Abstract: This study aims to determine the specific heat values of three types of metals, namely aluminum, brass, and copper, using the calorimeter method based on Black's Principle. The experiment was carried out by heating the metals to a certain temperature and then transferring them into a calorimeter containing water. The equilibrium temperature was recorded to calculate the heat absorbed by the water and the heat released by the metals. The results showed that the average specific heat values obtained were 0.42 cal/g℃ for aluminum, 0.16 cal/g℃ for brass, and 0.13 cal/g℃ for copper. These results are consistent with the theoretical values, although there are deviations caused by heat loss to the environment and limitations of the measuring instrument. Critical analysis identified that the use of an analog thermometer and suboptimal calorimeter insulation were the main factors of inaccuracy. As a recommendation, the use of a digital temperature sensor and the addition of thermal insulation can improve measurement accuracy. This study concluded that the calorimeter method can be used to determine the specific heat of metals with a sufficient level of confidence, provided that interfering factors can be minimized.

Abstract: The design of this sound resonance lab tool was made to compare the speed of sound propagation in the air in two types of pipes, namely small and large diameter pipes. The working principle of the tool is based on the resonance phenomenon that appears when the pipe is dipped in water, then the length of the air column that produces harmonic tones is sought using a frequency generator application at 1250, 1500, and 1750 Hz. The simple and easy-to-use tool design helps expedite the experimental process. From the results of the experiment on a small pipe, for frequencies of 1250, 1500, and 1750 Hz, the length of the air column was obtained as 13.603 cm, 11.33 cm, and 9.73 cm, respectively, with sound speeds of around 340, 340, and 340.5 m/s. In the large pipe, the results were almost the same: air column lengths of 13.6 cm, 11.34 cm, and 9.73 cm with sound speeds of 340, 340, and 340.5 m/s, respectively. From all these measurements, it can be concluded that there is no significant difference between the small and large pipes. The pattern of the relationship between frequency and air column length also remains the same, namely, the higher the frequency, the shorter the length of the resonating air column. Meanwhile, the speed of sound in air remains in a constant range, namely between 340 and 340.5 m/s.

Abstract: This study aims to analyze the effectiveness of Classroom Action Research (CAR) in improving students’ learning outcomes in science learning at the senior high school level based on a review of 50 reputable national and international journal articles. The research method used was a literature review with a qualitative descriptive approach. Data were analyzed based on learning problems, CAR cycle design, research subjects, instruments, data analysis techniques, and research results in each cycle. The findings indicate that the systematic implementation of CAR through planning, action, observation, and reflection stages significantly improves students’ learning outcomes, learning activities, and learning mastery in each cycle. Most studies reported a consistent increase in cognitive achievement and conceptual understanding from cycle I to cycle II. Therefore, Classroom Action Research is proven to be an effective and reflective approach to improving the quality of science learning in high schools.
