To resolve this, lesson study for learning community (LSLC) can be applied. There is a learning community that have role to improve teacher competence in every learning process so learning models implementation can be optimally implemented according to the syntax. The purpose of this research is to know the influence of guided inquiry learning (GIL) model based on LSLC in topic basic laws of chemistry to students grade X SMA N 9 Padang learning outcomes. The research subject was students of class X3 as experiment class and X4 as control class. The research method is quasi-experiment with pretest-posttest control group design. The research instrument is pretest-posttest questions and analyzed with n-gain test, normality test, homogeneity test, and hypothesis test. Based on data processing, the average n-gain of experiment class is higher than control class 0,6&gt;0,3 and conclude there was an increased learning outcome in experiment class. Based on hypothesis test use t-test, tcount&gt;ttable 2,99&gt;1,667 so can be conclude there is an influence of implementation GIL model based on LSLC to student learning outcomes.</p> 2022-05-15T00:00:00+00:00 ##submission.copyrightStatement## https://ejournal.unesa.ac.id/index.php/journal-of-chemical-education/article/view/43678 Penerapan Teknologi Pembelajaran dalam Permainan Kartu UNO Kimia Unsur di Lingkungan Pondok Pesantren 2022-05-15T16:38:39+00:00 Siti Aisyah sitiaiisyahh090@gmail.com <p>Penelitian ini bertujuan untuk menerapankan teknologi pembelajaran dalam permainan kartu uno kimia unsur dilakukan di lingkungan pondok pesantren yaitu MA An Nur Banyuates, Kabupaten Sampang, Jawa Timur.

The purpose of this research is to assess the success rate of the Project Based Learning (PjBL) model in empowering student creativity in class XI IPA SMA N 11 Muaro Jambi for the subject of buffer solutions, as well as to determine the extent of the correlation between the PjBL model and student creativity. This research method employs a mix method based on a sequential explanatory design. Purposive sampling was used to assign the research subjects to class XI IPA 2. The research data were examined both substantively and correlatively. The findings revealed a proclivity for the PjBL model to be successfully taught for three consecutive meetings, with an average achievement of 44.14 ±3.51; 64.04 5.13; 75.25±3.70, which falls into the good category. The success of this model is also related to the trend of increasing student learning creativity at each meeting, as evidenced by their respective average scores of 21.32±6.54;&nbsp; 46.14±7.92;&nbsp; 63.89±9.99. This finding is supported by a positive correlation between the success of the PjBL model and students' creativity in studying buffer solutions, with a value of r xy = 0.66 (the strong category) and a coefficient of determination of 43.56% (medium criteria).</p> 2022-05-15T00:00:00+00:00 ##submission.copyrightStatement## https://ejournal.unesa.ac.id/index.php/journal-of-chemical-education/article/view/45593 THE INFLUENCE OF THE NATURAL PRODUCT CHEMISTRY LABORATORY ON DECISION MAKING SKILLS 2022-05-15T16:38:40+00:00 Aliefman Hakim aliefman@unram.ac.id Abdul Wahab Jufri awahabjufri@unram.ac.id Jamaluddin Jamaluddin jamal.fkip@gmail.com Devi Ayu Septiani dedev22.deviayuseptiani@gmail.com Baiq Nila Sari Ningsih 6110220044@email.psu.ac.th Supriadi Supriadi supriadi_fkip@unram.ac.id <p><em>The study of secondary metabolites is the core of Natural Product Chemistry. The process of isolating secondary metabolites from Sasambo plants, which are medicinal plants used by indigenous tribes in West Nusa Tenggara province, Indonesia, has the potential to be integrated into the Natural Product Chemistry Laboratory. Students learn how to extract, fractionate, purify, and identify the structure of secondary metabolites through Natural Product Chemistry Laboratory activities. With various alter-native actions related to the process of isolating secondary metabolites, these laboratory exercises can be utilized to help stu-dents improve their decision-making skills. This study aims to investigate the impact of Natural Product Chemistry Laboratory Based on Medicinal Plants Sasambo (NPCL-MPS) on students' decision-making skills. This is quasi-experimental research with nonequivalent control group pretest-posttest research design. The participants are 63 students who enrolled in 6th semester students of the chemistry education department at one of the state universities in West Nusa Tenggara, Indonesia, for the 2019/2020 academic year, which were divided into experimental and the control classes. The findings show that the NPCL-MPS does positively influences students' decision-making skills.</em></p> 2022-05-15T00:00:00+00:00 ##submission.copyrightStatement## https://ejournal.unesa.ac.id/index.php/journal-of-chemical-education/article/view/45633 Penerapan Model Kooperatif dan Direct Instruction untuk Melatihkan Keterampilan Komunikasi Siswa pada Materi Asam Basa di SMA Negeri 1 Bangsal Mojokerto 2022-05-15T16:38:40+00:00 Firda haqiqi firdahaqiqi@mhs.unesa.ac.id Rusmini Rusmini rusmini@unesa.ac.id <p>Telah dilakukan penelitian tentang penerapan multi model untuk melatihkan keterampilan komunikasi siswa.
