LKPD (Student Worksheet) based on discovery learning is intended to provide learning knowledge directly in the process of meaningful learning activities so as to direct students to find learning concepts. This study aims to determine the level of feasibility, practicality and effectiveness of LKPD based on Discovery Learning to train students' critical thinking skills on respiratory system material. Researchers used the R&D (Research and Development) method using a 4-D development model (Define, Design, Development and Desemminate) developed by S. Thiagarajan, Dorothy S. Semmel, and Melvyn I. Semmel in 1974. The test subjects in the study consisted of 36 students from class XI IPA SMA PAB 4 Sampali. The results showed that the feasibility value of developing LKPD from material experts was 86.1% with the very feasible category and LKPD experts by 75% with the feasible category. Then the percentage of practical scores for LKPD development from biology teachers and students of science XI was 82.14% and 83.47% respectively with the practical category. The effectiveness of LKPD development based on individual completeness from the pre-test and post-test students obtained an average N-Gain score of 62.14, so the use of the method has been effective because the N-Gain normality value obtained between 0.30 < g < 0.70 with the "effective" criterion. Then for the N-Gain score value of 0.62, this value is in the medium category because the N-Gain score is between 0.3-07 with the category "medium N-Gain". From the overall results including valid, practical and effective categories, it can be concluded that LKPD based on Discovery Learning on the equipment system material is suitable for use and distribution to PAB 4 Sampali High School.

This study is based on students’ inability to solve problems in psychotropic material, which is caused by students' low reasoning power and tendency to memorize the material. To address these issues, consider using PBL-based e-pocket book media used for this study. The purpose of this study is to develop e-pocket book media based on PBL that are feasible, practical, and effective in improving students' problem-solving skills and motivating them to learn. The research was conducted in November 2022 - May 2023. The RnD research method was used in conjunction with the ADDIE development design. Interview guidelines, learning observations, expert assessment sheets, teacher and student response questionnaires, and student motivation questionnaires in learning were used to assess learning. The qualitative data analysis was obtained from media and material expert advice, teacher and student response questionnaires, student motivation questionnaires, learning observations, and interviews. The validation result of media experts yielded a quantitative 96% very feasible category while material expert validation yielded a 92% very feasible category. The results of the teacher's response questionnaire were 91%, while the student response was 89% in the very practical category. A questionnaire on student motivation in learning after using e-pocket book media was also obtained by 86%. Furthermore, the results of the independent sample t-test, show the result where Tcount>Ttable. It can be concluded that PBL-based e-pocket book media is very feasible and practical to use in learning and can improve students' problem-solving abilities on psychotropic material and motivate students in learning.

The mathematics learning process at high school level often faces challenges in terms of difficulties in understanding concepts. Conventional learning media is not interesting and interactive enough so it is less effective in understanding the material. This research aims to produce learning media using PowerPoint on the subject of statistics for class X. The development model used is the R&D model with the ADDIE development pattern, which consists of five stages: analysis, design, development, implementation and evaluation. The data collection technique used was a questionnaire. Data collection instrument that will obtain quantitative and qualitative data. Qualitative data was obtained from suggestions and input, while quantitative data was obtained from questionnaire calculations. The data analysis technique used is validation data analysis and learning media practicality data. The results of research validation analysis by three validators, namely media experts, material experts and learning experts using a Likert scale, show that the average validation of learning media is in the very feasible category. Apart from that, the results of the analysis of student response questionnaires, which involved thirty-two students, showed that the learning media obtained an average that fell into the very practical category. The conclusion of this research is that the interactive PowerPoint learning media on the subject of statistics, the material focusing on single data, has been tested and proven to be very feasible and very practical.”
