This research is a descriptive quantitative research, with a one group control posttest only research design, to analyze students' critical thinking skills in chemistry learning with an independent curriculum when viewed from gender differences. The population in this study is students senior high school in Jakarta, and the samples used in this study were 58 students consisting of 34 male students and 22 female students who were taken by random technique. Instrument test in this study was multiple choice questions consisting of 15 questions, which consisted of 3 sections according to Bloom's taxonomy, namely questions number 1-5 on C4, numbers 6-10 on C5 and numbers 11-15 on C6. The test instrument used is valid through the revision results according to the expert validator's input. The instruments used to obtain information regarding critical thinking skills were analyzed descriptively and the average male score was 56.67 (N=34), while for female it was 57.27 (N=22). Based on these data, the difference in critical thinking ability when viewed from gender differences is only 0.60 on a scale of 100 (Sig. <0.05). Furthermore, further test results show that there are differences in the critical thinking abilities of male and female students when learning chemistry in the independent curriculum.","PeriodicalId":17697,"journal":{"name":"Jurnal Pendidikan Kimia","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81926777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrolysis is a process that can decompose plastic waste and produce methane gas, liquid, and solid products. This study aimed to investigate the factors that affect methane gas production and the amount of methane gas produced during the pyrolysis of various plastics, including a black plastic bag and plastic with aluminium foil. The results showed that the aluminium foil plastic produced more methane gas than the black bag, with optimal gas content at 7.74% for the aluminium foil plastic and 3.48% for the black bag. The type of plastic, time, and temperature all significantly affected the yield of methane gas produced. In addition, the interaction between variables in plastic type, time and temperature greatly affects the yield of methane gas (CH4) obtained, because the type of plastic F count (2904) is higher than F table 0.05 (4.00), at temperature F count (5449) is greater than F table 0.05 (2.76), when F count (746) is greater than F table 0.05 (2.76). In conclusion, the snack foil produced more methane gas than the black bag because it was made of low-density polyethylene and contained aluminium ions that catalysed the decomposition of the material, resulting in an increase in the amount of methane gas produced.","PeriodicalId":17697,"journal":{"name":"Jurnal Pendidikan Kimia","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74807604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses the Systematic Literature Review (SLR) method using online article databases, namely ERIC and Google Scholar, which are limited to the last 5 years. The articles reviewed were 15 articles according to the topic. The results of the review show that the practicum e-module is in line with the curriculum in chemistry learning. Not to mention, practicum guides that go hand in hand with the times are very essential to be developed so that students can adapt well and learning becomes efficient with the current developing era. So, it is important to develop an electronic integrated practicum guide that creates balance between hard skills and soft skills in the curriculum concept. The validity of the chemistry practicum e-module from various applications in the implementation of online and offline practicum can be accepted by teachers and students, so that the teaching and learning process in proving theories in terms of practicum can be prepared. Especially in the future pandemic crisis, it is necessary to develop students' scientific literacy in terms of content, competence, context, and attitudes that are focused on preparing the next generation of scientific literacy through a culture-based curriculum to produce more contextual learning.","PeriodicalId":17697,"journal":{"name":"Jurnal Pendidikan Kimia","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80041921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research is a development research that aims to develop hydrocarbon chemical media. The development method used is ADDIE (Analysis, Design, Development, Implementation, Evaluation) which is modified by the researcher so that in this development research, only four stages are carried out, namely analysis, design, development and evaluation. The validation of the developed hydrocarbon chemical media was managed on a Likert scale of 1-4 by five expert validators, namely chemistry lecturers and teachers. The results of the analysis from the validation by expert validators on the feasibility of hydrocarbon chemical media according to the BSNP (National Education Standards Agency) modified with SETS eligibility are the content feasibility aspect of 3.58 (89.50 %); language feasibility aspect 3.68 (92.00%); presentation feasibility aspect 3.49 (87.25%); aspects of the feasibility of graphics 3.41 (85.25%); the feasibility aspect of implementing SETS 3.41 (85.25%). The average score of validation by the five validators is 3.54 with valid criteria and a presentation of 86.80% in a very feasible category. Based on the results of the validation of the hisrocarbon chemic media, it was concluded that the hydrocarbon chemical media was in accordance with the feasibility of the BSNP (National Education Standards Agency) modified with SETS eligibility and showed that the SETS-based hydrocarbon chemic media (chemistry comic) was very suitable to be used as a learning medium on hydrocarbon material.","PeriodicalId":17697,"journal":{"name":"Jurnal Pendidikan Kimia","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89452981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
