Abstract: Effectiveness of LKPD Based on Chemical Representation Using the Discovery Learning Model in Improving Science Process Skills in Chemical Equilibrium Material . This research aims to describe the effectiveness of chemical representation-based LKPD with discovery learning models in improving KPS in chemical equilibrium material. The population in this research is all students in class XI Science at SMAN 14 Bandarlampung for the 2022/2023 academic year. The sample was selected using purposive sampling technique. The sample in this research was class XI IPA 6 as the experimental class and XI IPA 5 as the control class. The design in this research is The Matching-Only Pretests-Posttest Control Group Design . The data analysis technique used is the difference test between two means with the Independent Samples t-Test. The research results show that the average KPS n-gain is in the high category in the experimental class and medium in the control class. The results of data analysis showed that there was a significant difference in the average KPS n-gain between the experimental class which applied LKPD based on chemical representation with the discovery learning model and the control class which used LKPD which was not based on chemical representation with the discovery learning model . Based on the research results, it can be concluded that the LKPD based on chemical representation with the discovery learning model is effective in increasing students' KPS in chemical equilibrium material.Keywords: LKPD based on chemical representation, discovery learning model, chemical equilibrium, science process skillsDOI: 10.23960/jppk.v13.i1.2024.12

Abstract: Enhancing Students' Analyzing Skills on Reaction Rate Topics Using the Guided Inquiry Learning Model. This study aims to describe the effectiveness of the guided inquiry learning model on reaction rate material in improving analysis skills. The population in this study were all students in grade XI at SMA Negeri 13 Bandarlampung in the 2023/2024 academic year, using purposive sampling technique obtained grade XI 6 as the experimental class and grade XI 7 as the control class. This study used the matching only pretest and posttest control group design. The data obtained were analyzed by calculating the average n-gain score of the pretest and posttest analysis skills. Apart from that, hypothesis testing was also carried out using an independent t-test. The research results showed that the n-gain of analytical skills in the experimental class was in the high category, and the average posttest score for analytical skills in the experimental class was higher than in the control class. Based on the research results, it is concluded that the guided inquiry learning model on reaction rate material is effective in improving analyzing skills.Keywords: guided inquiry learning model, reaction rate, analyzing skills.DOI: 10.23960/jppk.v13.i1.2024.16
