This study aims to find out whether there is an influence of the Problem Based Learning-Computational Thinking (PBL-CT) model on analytical thinking skills in terms of students' interest in Natural Sciences subjects. This research was conducted at the Kalam Kudus Christian Middle School in Malang in the 2022/2023 academic year. The design used in this study was a non-equivalent group design quasi-experiment. Retrieval of data using ten essay questions which are made according to indicators of analytical thinking ability and students' interest in science is measured by using a questionnaire.  Data analysis was carried out by the Two Way Anova parametric test. Based on the results of the analysis carried out, the results were obtained: (1) there were differences in analytical thinking skills between students who were taught using the Problem Based Learning and Problem Based Learning - Computational Thinking (PBL-CT) learning models with a significance <0.05. (2) there is no difference in the ability to think analytically between students who have a high, medium, and low interest in learning science as shown by a significance value of 0.748 > 0.05. (3) there is an interaction between Problem Based Learning - Computational Thinking (PBL-CT) on students' analytical thinking skills in terms of students' interest in natural science subjects with a significance value of <0.05

21st century learning has had a huge impact on students and teachers. Students must be guided to be able to think critically to overcome various kinds of problems that occur. Furthermore, teachers as education play an important role in honing problem solving skills in their students. The problem solving learning model is a learning model that directs students to solve problems in the learning process. In addition, the problem solving learning model is not fully capable of being applied by science teachers. Although, in the 2013 curriculum in Indonesia a teacher is required to be able to apply the problem solving model in conducting science learning. Not only that, the limited experience of teachers in applying variations of these learning models is still the main obstacle in learning science. So, teachers in Indonesia must have extensive experience in adopting problem solving learning models. This study aims to determine the effectiveness of the problem solving learning model in learning science in Indonesia. This research is a kind of meta-analysis research. The research sample came from analyzing national and international journals published from 2010-2022. The selection of data used as samples was carried out very strictly and thoroughly. Searching for this research sample through Google Scholar, Eric, Hindawi, Sage, Springer, Proquest, IEEE, DOAJ, and Wiley. The sample selection technique is a purposive sampling technique. In this technique, the data that is used as a sample must have a relationship with the research variable. In searching for sample keywords, namely problem solving learning models in learning science (Biology, Chemistry and Physics) in various schools in Indonesia. Data analysis is descriptive statistical analysis with the OpenMEE application. Data analysis was performed by calculating effect size, standard deviation (SD), average value (mean), and N-gain. The results of this study concluded that the application of the problem solving learning model was very effective in learning science in Indonesia. This learning model is able to increase student learning outcomes with an average score of 86 students in the experimental class and 65.5 in the control class, the effect size value is 1.39 in the high category and N-Gain is 0.55.

Humans have the ability to think and always try to improve their knowledge. Human nature is naturally full of curiosity so humans are always looking for answers to their curiosity. Humans seek answers to their curiosity through knowledge, and through knowledge will lead to its own satisfaction according to the demands of the times. The knowledge gained is not only knowledge, but is emphasized on knowledge and truth. Learning everything by studying the right scientific foundation is one of the efforts made by humans to obtain the truth. This study aims to determine the nature of the philosophy of education in the development of science based on local wisdom. The surrounding nature gives birth to local wisdom that is unique and is a potential in the development of science. Science or science which includes physics, chemistry, biology using scientific steps, scientific thinking, and using scientific frameworks. This is the beginning of the philosophy of science used to study, uncover, and solve scientific problems for human life. This study discusses the importance of a person in developing science based on local wisdom as a means of maintaining natural resources, culture, customs that exist in people's lives.

In the era of globalization, the world of education has made very significant progress in all fields. All have been based on the use of information and communication technology in the teaching and learning process. Technology acts as a tool to help students and teachers in conveying information more effectively. However, students have not been able to master technology-based learning materials. So, teachers must facilitate and monitor student performance so that they can more easily and quickly master the material. The professional quality of teachers in Indonesia is still relatively low. This is because the human resources of the Indonesian people are still lagging behind compared to other countries. The quality of teachers in Indonesia needs to be improved by using a learning approach. Learning approach based on Technology Pedagogical Content Knowledge (TPACK). This TPACK approach makes it easier for teachers to master technology that is by learning content so that students are motivated and active in learning. This study aims to determine TPACK-based learning in supporting the quality of teachers in Indonesia. This research uses the type of library research. Research samples from literature studies sourced from Google Scholar and Eric Journal. The criteria for the data to be sampled are articles published in 2015-2022. The data that was used as a sample amounted to 15 articles that were following the research variables. Data analysis is qualitative data analysis. The results show that from 15 articles that have been analyzed, TPACK-based science learning is very helpful for science teachers in Indonesia. TPACK-based science learning enhances the professionalism of teachers in teaching science material. Furthermore, the TPACK approach greatly helps teachers' professional performance to be more effective and efficient in mastering technology for learning facilities

The Order for Termination of Investigation or hereinafter referred to as SP3 is the authority given attributively to criminal investigators. This paper intends to provide an analysis in terms of normative law regarding the validity of the termination of an investigation carried out based on reconciliation between the suspect and the complainant in the case of ordinary offenses. Research is a main means in developing a science and technology with the aim of revealing the existence of a truth both systematically, methodologically, and consistently through the research process as well as conducting analysis and construction of the data that has been processed and then concluded. Article 109 Paragraph (2) of Law Number 8 of 1981 concerning the Criminal Procedure Code (KUHAP) states that there are three conditions to stop an investigation of a criminal act. First, there is not enough evidence. Second, the act committed by the suspect is not a crime. Third, the investigation was stopped for the sake of law. The fact that the revocation of the police report resulted in the case being discontinued or terminated, as evidenced by the issuance of an Investigation Termination Order or SP3.
