This study aims to investigate the effect of the discussion experimental method on understanding the concept of physics in grade VII students of SMP Negeri 9 Palu. This research was a quasi experimental study using the equivalent prestest-postest design. The sample was selected using purposive sampling technique and resulted in class VIIC as the experimental class and class VIID as the control class. The instrument used was a test of understanding the concept of physics in the form of essays totaling 10 questions that had been validated through expert validity. The results of data analysis obtained that the mean pretest score of students' understanding of physics concepts in the experimental class was 19.25, the standard deviation was 2.92, while the mean posttest score was 31.33 with a standard deviation of 3.76. For the control class, the mean pretest score was 18.95 with a standard deviation of 2.32, while for the posttest mean score was 25.14 with a standard deviation of 3.58. Data analysis was performed using the two-party t-test statistical technique with a significant level of α = 0.05. Obtained the value of t count = 5.83 and t table = 2.02, with an ideal score of 40. This means that the value of t count is outside the area of acceptance Ho. These results indicate that there is a difference between the experimental class and the control class. It can be concluded that there is an effect of the discussion experimental method on the understanding of the physics concept of grade VII students of SMP Negeri 9 Palu.

The instrument used is a test of physics learning outcomes in the form of multiple choice that has been tested and data analysis techniques. Based on the results of data processing, for the experimental class, the average final test score was 8.80 with a standard deviation of 3.30. For the control class, the average final test score was 6.10 with a standard deviation of 3.11. The results of hypothesis testing obtained tcount = 3.43 and ttable = 2.02. This means that the value of tcount is outside the H0 acceptance region. These results provide an opportunity to state that there are differences in physics learning outcomes between the control class and the experimental class. Thus, it can be concluded that there is an effect of the time token type of cooperative learning model on the physics learning outcomes of seventh grade students of SMP Negeri 1 Banawa Tengah.

This study aimed to know the effect of the Two Stay Two Stray (TSTS) type cooperative learning model on physics learning outcomes. This type of research was a quasi-experimental design with a non-randomized pretest-posttest control group. The population of this study were all students of class X SMA Negeri 5 Palu. The sampling technique used in this study was purposive sampling with the research sample being class X MIPA 3 as the experimental group and class X MIPA 4 as the control group. The instrument used is a test of learning outcomes in the form of multiple-choice questions. The increase in the average N-Gain in the experimental class was 50.88% while in the control class it was 22.68%. Based on the hypothesis test t-test (one party) obtained tcount = 2.88 and t0.975 (67) = 2.00 at the real level = 0.05. This means that the value of tcount is outside the acceptance area of H0. So it can be concluded that there is an effect of student learning outcomes using the Two Stay Two Stray (TSTS) type cooperative learning model on physics learning outcomes in class X SMA Negeri 5 Palu

The purpose of this study was to determine whether there is an effect of the recitation method in the cooperative learning model to improve the learning outcomes of heat and its transfer. This type of research was quasi-experimental. The sampling technique was purposive sampling. The samples of this research were students of class VII A and VII B of SMP Negeri 3 Bulagi. Class VII A is the experimental group and class VIIB is the control group. The learning outcome test instrument was a multiple-choice test. Based on the results of data processing, the N-gain value in the experimental group was obtained at 45.97%, which was in the medium category. Then for the control group, the N-gain value was obtained at 33.43%, which was also in the medium category. These results indicate that the learning outcomes of physics in the experimental group are higher than those in the control group. The results of statistical calculations from the average difference test using t-test (two-tailed) obtained tcount > ttable (tcount = 4.22 and ttable = 2.02) at a significance level of 5% and dk = 45, thus H0 is rejected and H1 is accepted. So, it can be concluded that there is an effect of the recitation method in the cooperative learning model to improve the learning outcomes of heat and its transfer.

This study aims to identify students scientific reasoning ability in Palu city and the correlation between studentsâ€™ scientific reasoning abilities and their cognitive aptitude within the context of physics education. In this study, we adopted a descriptive quantitative research method where the respondents consist of four high schools in Palu city, namely SMAN 1, SMAN 7, SMAN 6, and SMAN 4 Palu. An instrument by Lawson (LCSTR) was adapted for this study and it consist of 12 items two tier multiple-choice that contains conservation of mass and volume, proportional thinking, control of variables, probabilistic thinking, correlational thinking, and hypothetical deductive reasoning. Meanwhile, for the cognitive understanding test, we utilized a static fluid concept comprehension test. The findings of this research using SPSS to analyzed find that Pearson correlation coefficient is 0,54 that revealed significant correlations between studentsâ€™ scientific reasoning abilities and their cognitive aptitude in the context of physics learning. These correlations provided valuable insights into how these components influence each other and impact studentsâ€™ performance and achievement in physics. The studyâ€™s result has implications for educators as a reference in the selection of models and methods of physics learning appropriate to train and develop students scientific reasoning skills.

Solar thermal power generation using thermoelectric technology offers promising potential for renewable energy use in Palu, Indonesia, providing a clean and sustainable source of electricity for low-power electronic devices. This approach not only reduces greenhouse gas emissions but also supports sustainable regional development by offering an alternative to fossil fuels, thus strengthening long-term energy resilience. Additionally, utilizing renewable energy can foster local economic opportunities and decrease energy import costs. This study employs a thermoelectric generator (TEG) that converts heat focused through water lenses into electrical power via the Seebeck effect. The system’s performance depends on the temperature difference created between the heated and cooled sides of the thermoelectric module. Experimental results showed a voltage range of 0.1 V to 0.33 V, producing a current of about 0.001 A, with an output power of 1.0 × 10⁻⁴ W to 3.3 × 10⁻⁴ W. Though the current output supports low-power devices, further optimization is required to enhance efficiency. This research underscores the viability of water lens-based thermoelectric systems as an eco-friendly energy solution in solar-rich regions, presenting a potential pathway for sustainable energy generation.
