This study aims to improve problem-solving skills and learning achievement by applying the Karplus Learning Cycle Model on students of class VC of SD N 2 Padokan Bantul, totaling 20 students. This research was a classroom action research and was carried out in two cycles. Data collection techniques were test and non-test. Students? problem-solving skills data were collected using pretest and posttest as well as observation sheets, while science learning achievement of students was taken using pretest and posttest. The data were analyzed using descriptive analysis techniques. The results showed that problem-solving skills and learning achievements of the students in class VC SD N 2 Padokan can be improved through learning with the Karplus Learning Cycle Model. Each stage of the Karplus Learning Cycle Model can improve aspects of problem-solving skills and student learning achievement. The Exploration stage increases the aspect of understanding the problem. The Explanation phase enhances the aspects of planning a solution. The concept application stage improves aspects of solving problems and evaluating problem-solving. Improved problem-solving skills are proven through test results, where the average N gain of class in the first cycle was 0.37 with the moderate category, up to 0.70 with the high category in the second cycle. This is also strengthened from the results of observations, where the average scores of the class increase from the first cycle of 67.61% with a pretty good category to 91.66% with a very good category in the second cycle. The increase in student learning achievements is evidenced through the results of the test, where an increase in the number of students who reached KKM 75 from the first cycle as much as 90% to 100% in the second cycle.

Learning tools are things that must be prepared by educators before carrying out learning activities. Learning tools serve as guidelines and guidelines for teachers in implementing a systematic and integrated learning process. This study aims to find out how to develop and the feasibility of Inquiry-based science learning tools with Tri N teaching for seventh grade junior high school students. This research includes research and development (Research and Development) using the 4D development model consisting of Define, Design, Develop, and Dessiminate. However, the Dessiminate stage was not carried out on this development due to time and cost limitations. The instrument in this study was a questionnaire covering several aspects of the study. The quality of the RPP is assessed by expert lecturers and the quality of the LKPD is assessed by media experts, material experts, student experts, and peer reviewers. Quality value data obtained were analyzed using qualitative and quantitative descriptive analysis based on an ideal assessment. The results showed that Inquiry-based science learning tools with Tri N teaching for seventh grade junior high school students were deemed fit for use in science learning with the assessment of RPP products based on expert lecturers obtaining an idealized percentage of 79.16% and LKPD product assessments based on media experts with a percentage of ideals of 85.23%, material experts 96.42%, student expertise 96.42%, while peer reviewers 85.24%.

The objective of this study was to determine the effect of the Problem Based Learning (PBL) model on science learning outcomes of class VII students of SMP in terms of problem solving skills. This research was a quasi-experimental research design, using pretest posttest. Descriptive results showed that the tendency of science learning outcomes with PBL models was obtained on average in the experimental class of 22.67 including very high categories, and classes taught by the lecture method were 17.47 in the high category. Whereas for problem solving skills students taught with PBL obtained an average of 78.54 which included high and class categories taught by the lecture method of 70.38 which included the high category as well. Based on the test of the Anakova obtained Fcount = 10.723 with p = 0.002. From the data obtained, the hypothesis was accepted and significant. Comparatively there were very significant differences in science learning outcomes of class VII students between PBL learning model and the expository model in terms of students' very significant problem solving skills.

This study aims to explore ethnoscience at the stage of dyeing woven fabrics, recommending science teaching materials related to Buton woven fabrics, especially in natural dye additives, and inviting the public to preserve the culture of woven fabrics. Ethnoscience is the science that is used to understand how people's original knowledge in the process of dyeing woven fabrics can be constructed into scientific scientific knowledge. The dyeing of the weaving threads is still done traditionally by using materials obtained from nature. The research was conducted in the Colorful Weaving Village. This research is a qualitative descriptive research through the process of data reduction, data presentation, drawing conclusions, and verification. The research data collection was carried out through observation, interviews, and documentation. Triangulation of sources by comparing the results of interviews with journal sources and websites. The results showed that at the stage of dyeing Buton woven fabrics, they contained junior high school science concepts, namely plant classification, natural dye additives, substance particles, molecules, simple planes, energy changes, solution concentration, and physical changes that could be used in contextual science learning. in school.
