The purpose of this study was to describe the application of the think-pair-share method with article analysis to improve students' higher order thinking skills. This type of research is pre-experimental with research subjects, namely students who take the Physics Learning Strategy course, academic year 2020/2021, at one of the universities in Mataram, totaling 27 people. The research design used was One Group Pre-test and Post-test Design. The instrument used in this study was a test of higher order thinking skills. The level of higher order thinking skills of students is calculated as a percentage, with 5 categories. The increase in score is calculated using N-gain, with 3 criteria. The results showed that the level of high-order thinking skills of students at the pre-test was 49 with a very low category, while at the time of the post-test it was 83 in the good category. The N-gain score is 68 with moderate criteria. Thus, the application of the think-pair-share method with article analysis can improve students' higher-order thinking skills in the Physics Learning Strategy course.

Student worksheets (LKPD) is the most significant aspect on the learning activities because it consists of the student’s learning process of gaining knowledge, primarily growing the critical thinking ability. The aim of the study is giving information about the development of critical thinking with LKPD process in physics subject. The method is Research and Development (RnD)-ADDIE which is limited on the development stage. Based on the evaluation result through validity which involve expert validity from the lecturer and the teacher, Content Validity Index (CVI) is 0,95 that means very suitable. The CVI result indicates that the LKPD process could be used to grow the physics critical thinking. The LKPD process has not arrived at implementation yet, hopefully the reseacher on the same field could apply till the implementation stage so that we could say LKPD process could grow the physics critical thinking.

Method has been carried out. Research is done on mild steel zincalume type with immersion treatment (NaCl 3.5%) for 10 days, and 30 days and without immersion. Mild steel is laser irradiated (Nd-YAG 1064 nm, 7 ns) with energy of 120 mJ, and the data is taken with an accumulation of 3, delay time of 0.5 µs. Elements identification is done by taking data from up to 75 μm from the surface. The results of the analysis with LIBS showed immersion for 10 days, the corrosion rate and hardness of mild steel increased with 30 days immersion. The increase in the corrosion rate of mild steel is indicated by decreasing the value of dissolved oxygen intensity, the electrochemical reaction is fast. The decrease in the corrosion rate is indicated by the increase in the intensity value of Zn and Al elements associated with the formation of a passive film on the metal surface as a protective layer to protect further corrosion attacks.

This study aims to train students' critical thinking skills during the learning process using CCM-CCA assisted by virtual experiments. The material used for research in optics. This type of research uses a quantitative approach. The subjects in the research were 30 physics education students at a university in NTB. The ability to think critically during the learning process is trained with student worksheets equipped with instruments for critical thinking. Learning is carried out for 3 meetings. The results showed that there was an increase in students 'critical thinking skills from the low category with an average score of 38 to the high category with an average score of 75. This fact shows that CCM-CCA learning assisted with virtual experiments can train and even improve students' critical thinking skills in Optical material.

Inetractive learning media is a medium that can help students and teachers in learning. This study aims to see the role of science teachers in the use of instructional media. This type of research is qualitative non-experimental. The population of this study were students of SMPN 2 Singai Aur Pasaman Barat. Sampling using purposive sampling. Data were collected through a questionnaire with 2 indicators. Based on data analysis using statistical data in the form of percentages and relative frequencies, it was found that the indicator of teacher control of the media used had a score of 94.61% and the media indicators used were good, efficient, and could attract the attention of students in the learning process 88.31% so that it could be concluded that the role of science teachers in the use of interactive learning media has a score of 91.46% with a good category.

This research is a development research that aims to produce a modern physics learning tool with guided inquiry model assisted by virtual media. The development of this learning tool is carried out using the 4D model which consists of 4 development stages, namely the definition stage, the design stage, the develop stage, and the deseminate stage. The definition stage is carried out to identify problems, the design stage is carried out in the form of designing a guided inquiry learning device, and the dissemination stage is carried out in the form of distributing learning tools to physics education lecturers. The learning tools developed were syllabus, leasson plan, student worksheet, and tests of students' scientific creativity and science process skills. The use of learning tools with a guided inquiry model assisted by virtual media aims to help students' scientific creativity and science process skills. However, in this paper, it is focused on the validation test process through validation tests on developing the tools that are made. The final result of this research is to produce a product development of instructional models assisted inquiry model with virtual media that is valid and suitable for use.

The research has been done using geoelectric resistivity method to estimate the volume of Manganese (Mn) carrier rock in Empol sub-village, Central Sekotong Village, West Lombok NTB. Measurements was conducted with the Wenner configuration using a Resistivity Meter G-Sound GL - 4100. Data was modeled and calculated using three software, there are Res2Dinv 3.5, Surfer 10, and Rockwork 15. The rocks that regarded as carrier mangaan is pyrolusite manganese (Mn02). The description and distribution of MnO2 can be determined from the results of 2-dimension modeling using Res2Dinv. Mn02 was detected in almost all resistivity line with value around 0,023 m up to 9,8 m. From the 3-dimension visualization processed using RockWorks 15 software, we obtained volume of pirolusit about 38,199 m3 of area 160,000 m2 and 100 m of thickness.

This study aims to examine the concept of the nature of science (NOS) and attitudes towards teaching the NOS. The research used the View on Science Education (VOSE) instrument that was developed by Chen (valid and reliable) which online distributed to students of Physics Education Program from Surabaya State University and IKIP PGRI Pontianak, as well as students of Science Program from IAIN Ponorogo. The survey research method was conducted to determine the profile of students’ views on the NOS and science education. Respondents who filled out the research questionnaire were 102 students. Based on the survey results, the VOSE profile was obtained that the Science-Physics students had difficulty conceptualizing the general picture of VOSE because in some aspects of NOS it appeared that students experienced confusion.Science-Physics students have a positive attitude towards teaching NOS in terms of tentativeness, aspect of the nature of observation, as well as aspect of theory and law.However, Science-Physics students have negative attitudes towards teaching NOS in the aspect of the scientific method. Thus, the implication of this research requires that Science-Physics students learn and further research about the concept of NOS in order to have a correct understanding.
