Abstract

To improve students' interest and learning outcomes in science, it is necessary to apply an innovative learning model assisted by interactive media so that the learning process in the classroom becomes more interesting, so that it can increase students' interest in learning which will later affect student learning outcomes. One innovation that can be applied to improve students' interest and learning outcomes is to use an innovative learning model, namely the TGT (Team Game Tournament) cooperative learning model assisted by interactive wordwall media. This study aims to describe the differences in students' interest in learning science, students' learning outcomes, interests and learning outcomes of science simultaneously in students who are taught using the TGT type cooperative learning model assisted by interactive wordwall media with students who are taught using the TGT type cooperative learning model. This type of research is a quasi-experimental researchs. This study uses a quantitative approach. The design of this study uses the Nonequivalent Pretest Posttest Control Group Design. The results of this study indicate that: a significance value of less than 0.05 was obtained, a significance value of less than 0.05 was obtained, a value of less than 0.05 was obtained, so it can be concluded that there are differences in interest and learning outcomes simultaneously in groups of students who are taught using the TGT type cooperative learning model assisted by interactive wordwall media with students who are taught using the TGT type cooperative learning model.

Abstract

This study aimed to examine the effect of a Problem-Based Learning (PBL) model integrated with ethnoscience on students’ energy literacy and learning outcomes compared to conventional PBL. A quasi-experimental design was employed using a non-equivalent control group with pre-test and post-test. The population consisted of all 67 Grade X students at SMA Negeri Satu Atap Lembongan, who were divided into experimental and control classes based on their existing class groupings. The experimental group received instruction using the ethnoscience-integrated PBL model, while the control group was taught using standard PBL. Data were collected using validated instruments assessing energy literacy (knowledge, attitudes, and behavior) and cognitive learning outcomes. Results of analyzed using MANCOVA showed that the experimental group experienced significantly higher gains in both energy literacy (p < 0.05) and learning outcomes (p < 0.05) compared to the control group. The findings suggest that integrating ethnoscience into PBL provides contextual relevance and enhances the effectiveness of science instruction. This model can serve as a culturally responsive approach to improve students' scientific understanding and engagement.

Abstract

Activated carbon is an amorphous carbon material predominantly composed of free carbon atoms with high adsorption capacity. The amorphous structure in activated carbon affects its adsorption capacity; the higher the percentage of amorphous carbon, the greater the adsorption capacity of the activated carbon. Activated carbon can be obtained from rice husk waste containing 30-40% C in cellulose, hemicellulose, and lignin. Therefore, this study was conducted to observe activated carbon's phases, morphology, elemental composition, and particle size. Activated carbon was synthesized using a physics-chemical activation method, which began with washing the rice husk samples, followed by air drying, carbonizing into charcoal, and grinding it finely. The rice husk charcoal powder was then physically activated at a temperature of 500℃. The physically activated product was then chemically activated using 6M HCl with a charcoal-to-activator ratio of 1:10 (m/V), stirred at 250 rpm for 1 hour, and then allowed to settle for 24 hours. It was then washed and dried to produce activated carbon powder. XRD test results showed diffraction peaks at 2θ = 22.23° without sharp or pointed peaks, indicating that the activated carbon has an amorphous structure. SEM test results showed the morphology of rice husk-activated carbon with spherical particle shapes and a particle size distribution of 20-70 nm. EDX test results showed that the rice husk activated carbon is predominantly composed of C, O, and Si with respective percentages of 54.31%, 40.04%, and 2.49%.

Abstract

Misconception is a mismatch between the concept that a person believes and the scientific concept according to experts. The occurrence of misconceptions can affect one's knowledge of the next concept. This study aims to describe the profile of students ' misconceptions and find out the difficulties experienced by students on the material heat and temperature. This survey research was conducted on class X MA students totaling 24 students. Data were obtained through a web-based four tier diagnostic test consisting of 10 questions. Students' answers were categorized into 3 categories, namely understanding the concept, misconceptions, and not understanding the concept. The results showed that students had misconceptions with an average percentage of 41%. Students have the most misconceptions in the sub-material of the effect of heat on temperature changes with a percentage of 66%. Based on the results of the interviews, it was found that the average student had difficulty in several sub-materials, namely the concepts of specific heat, temperature, expansion, and the effect of heat on changes in temperature and phase. This research needs to be followed up to overcome students' misconceptions on heat and temperature.
