This research aims to: 1) To determine the differences in students' learning motivation and understanding of concepts in global warming material between learning that uses a guided inquiry model through outdoor learning and learning that takes place conventionally. 2) To determine the magnitude of the increase in learning motivation and understanding of concepts in global warming material between learning that uses a guided inquiry model through outdoor learning and learning that takes place conventionally. This research includes research with a quantitative approach. The method used is Quasi Experimental Design. This research used a pretest-posttest with two groups, namely the experimental group and the control group. Data analysis techniques use preliminary tests of normality, homogeneity, and use hypothesis analysis with the T test and Gain test assisted by SPSS.24. The results of this research show that: 1) In the first follow-up test, namely the t test on students' conceptual understanding data, a significance value of 0.00 < 0.05 was obtained, so that Ha was accepted and H0 was rejected. For learning motivation data, a significance value of 0.00 <0.05 was obtained, so that Ha was accepted and H0 was rejected. It can be concluded that there are significant differences in students' conceptual understanding and learning motivation. 2) There is an increase in understanding of concepts with an average N-Gain score in the experimental class of 64.657 or 64.6% with medium criteria, while in the control class it is 27.32 or 27% with low criteria. The N-Gain calculation of learning motivation for the experimental class received a score of 68.550 or 68.5% with medium criteria, while for the control class it was 3.96 or 3% with low criteria. From these results it can be concluded that the guided inquiry model through outdoor learning is effective in increasing students' learning motivation and understanding of concepts in global warming material compared to conventional learning.

Advances in technology have a huge impact on the development of physics, the tracker application is one example of technological developments in the field of physics that can solve problems in analysing videos of the motion of an object recorded using a smartphone. One of the motion phenomena that can be analysed using the tracker application is the oscillatory motion of an elastic pendulum. The purpose of this research to know the analysis of elastic pendulum motion in the form of oscillation trajectory and period using tracker application. The method used in this research is experimental method. The results of the analysis obtained from this research are that the oscillation trajectory of the elastic pendulum does not move the same or irregularly when oscillating, and the period that occurs in the oscillation of the x and y axes against time (t) is relatively constant.

Abin Hernandi, Resti Warliani, Asep Irvan Irvani — Mon, 30 Sep 2024 00:53:50 +0000

Critical thinking skills are a thinking skill that is very necessary, one of which is in learning physics. This research explores the importance of critical thinking skills for students and how the Talking Stick model can improve these skills. This research data was obtained from secondary data using the Systematic Literature Review (SLR) research method. The research stages were carried out in accordance with the PRISMA diagram rules, namely identification, screening and included. Through these stages, the final result was 21 articles obtained through the database in the Publish or Perish software. The data obtained was then analyzed using the content analysis method. Based on the results of the analysis, it was found that students' critical thinking skills could improve through the Talking Stick learning model with an average percentage increase of 58.91% with the highest increase being 65,38%. In order to obtain better results of students' critical thinking skills, the support and cooperation of teachers and all related parties is very necessary to play an active role in enriching students' learning experiences in order to improve students' critical thinking skills in physics learning. So it can be concluded that the talking stick learning model can improve students' critical thinking skills.

Allan Asrar, Zulpadrianto Z — Tue, 05 Nov 2024 12:21:16 +0000

This study aims to develop PjBL (Project-based Learning) based teaching materials in the context of magnetic electricity learning and measure its impact on improving students' experimental abilities. The development method of these teaching materials follows the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The analysis stage includes the needs of teaching materials, student characteristics, and learning material analysis. The design of teaching materials involves creating flowcharts and interactive multimedia storyboards. Development involves realizing the product design in the form of e-modules and validating the product by experts. The implementation stage is carried out to test the learning outcomes using e-modules on students. Evaluation is conducted to assess the effectiveness of teaching materials based on the analysis results at the implementation stage. This research shows that PjBL-based teaching materials are effective in improving students' understanding of concepts and experimental skills. These findings provide a significant contribution to higher education development by strengthening project-based learning approaches to facilitate deeper understanding and practical skills in the field of magnetic electricity.

Analysis of Students' Science Process Skills in Physics Material in Online Learning

Salwa Rufaida, Riskawati Riskawati, Sindi Sindi — Tue, 05 Nov 2024 00:00:00 +0000

This study aims to analyze the science process skills possessed by students during online learning on physics material. The type of research used is descriptive research with a quantitative approach. In this study, instruments of physics science process skills will be distributed to 30 students of class XI who are in the top 10 at three high schools in Gowa Regency that are still implementing the online learning system to date, namely SMA Aksara Bajeng, SMA Handayani Sungguminasa, and SMAN 19 Gowa. Science process skills instruments are shared online. The data obtained were analyzed using descriptive analysis. The results showed that in general the science process skills possessed by the dominant students were in the low category with the highest frequency of 13 people, 12 people in the medium category, 4 people in the very low category and 1 person in the high category. Meanwhile, for each indicator of science process skills, of the 7 indicators, there are 4 indicators that are in the low category and 3 indicators are in the medium category. So it can be concluded that the students' science process skills on physics material in dominant online learning are still relatively low.

Sitti, Jumardin Jumardin, Nurul Fuadi — Sun, 08 Dec 2024 12:45:53 +0000

The preparation of solid hydroxyapatite (HAp) with variations in calcination temperature has been carried out. This study aims to determine the crystal size, dislocation density and crystallinity levels of HAp using XRD. HAp is made by mixing cuttlefish shell powder with a solution of KH₂PO₄, NaOH and Aquades then drying it for 24 hours. Extraction of CaCO₃ from cuttlefish shells using the calcination method at various temperature variations, namely 600 ⁰C, 800 ⁰C and 1,000 ⁰C. XRD test to determine the crystal size value, crystal defects and crystallinity of HAp material. XRD data shows that HAp solids form crystals with smaller sizes (50.97 nm, 48.64 nm and 36.52 nm) when the calcination temperature increases, dislocation density increase (0.38 nm^-2.10^-4, 0.42 nm^-2.10^-4 and 0.74 nm^-2.10^-4) as the calcination temperature increases and the crystallinity value decreases (46.31%, 39.06% and 37.93%) based on changes in calcination temperature.
