Abstract

Abstract This study aims to develop an e-LKPD based on Guided Discovery Learning and to determine the feasibility and student response to the e-LKPD. The development model used is the ADDIE model (analysis, design, development, implementation, evaluation) which is limited only to the development stage in the form of student response testing. The research was conducted from June to March 2023 at Bengkulu 1 Public High School. The research sample was taken by purposive sampling technique, namely class XI IPA 4, totaling 28 people for small group trials. The research instruments were interview sheets, student needs questionnaires, validation sheets, and student response questionnaire sheets. The resulting data consists of qualitative data in the form of suggestions from the validator and students as well as quantitative data on the results of validation sheets and student response questionnaires. Validation sheets and student response questionnaires use a Likert scale. The results showed that the chemical e-LKPD based on Guided Discovery Learning was declared very feasible by media and material experts with a media aspect percentage of 93.57% and a material aspect of 89.12%. Student responses to the e-LKPD were in the very good category with an average percentage of 91.13%, from the results of the study it could be concluded that the chemistry e-LKPD on Guided Discovery Learning-based reaction rates was very suitable for use as teaching materials.

Abstract

This study is a research and development of ICARE-based chemistry e-modules that aims to determine the feasibility of e-modules, student responses, and improvement of student learning outcomes. The development model used is analysis, design, development, implementation, evaluation (ADDIE). The research was conducted at SMA Negeri 2 Seluma from January to August 2022. The subjects of this study were X IPA 2 and X IPA 3 students in the 2022/2023 school year who were selected based on simple random sampling techniques with a population of 3 classes, which were then tested for normality and homogeneity so that normal and homogeneous classes were obtained, namely X IPA 2 class for small group tests and X IPA 3 for large group tests. The instruments in this study were interview sheets, validation sheets, student response questionnaires, and tests. From the results obtained (1) ICARE-based chemistry e-modules were declared very feasible by media and material experts with a percentage of 98.88% media aspects and 91.25% material aspects, (2) Student responses to ICARE-based chemistry e-modules were in the very good category with an average percentage of 90.23%, and (3) After using ICARE-based chemistry e-modules on redox reaction material, there has been an increase in student learning outcomes as measured by an average N-gain score of 0.69 on moderate criteria. The results of the development of ICARE-based chemistry e-modules are very feasible to use in the learning process and proven to improve student learning outcomes. Keywords: e-module, development, ICARE, learning outcomes

Abstract

This study aims to determine the differences in the activities and learning outcomes of students who apply the somatic, auditory, visual, intellectual (SAVI) learning model assisted by android-based teaching materials and practicum. This study uses a quasi-method with research samples of experimental class I used android-based teaching materials and experimental class II applying practicum. The method of data collection was carried out by conducting tests in measuring learning outcomes while the observation sheet of student activities in measuring learning activities. The results of observing the learning activities of students in the experimental class 1 and 2, respectively, are 69% and 74%, both in the active criteria. The cognitive learning outcomes of experimental class 1 and 2 students are 75.76 and 79.61, both in good criteria. There is a significant difference between learning activities and student learning outcomes who are taught by the application of the SAVI learning model assisted by android-based teaching materials and practicum. The results of the study can be concluded that in general the activities and learning outcomes of students with the application of the SAVI learning model with practicum are higher than those with the help of android-based teaching materials.
EFEK PEMBERIAN EKSTRAK AIR DAUN PLUKENETIA VOLUBILIS (SACHA INCHI) TERHADAP KADAR TRIGLISERIDA PADA MENCIT DIABETES MELLITUS Dewi Handayani; Zakiyah, Nesfitri Aufa; Amir, Hermansyah

Abstract

This research aims to determine the content of secondary metabolites and the effect of administration and effective dose of water extract of Plukenetia Volubilis (sacha inchi) leaves on triglyceride levels in diabetic mice. The research design is experimental with the pre-post test method and control group design. The samples used were 21 male white mice which were divided into 7 groups, namely the normal group, the positive control group (given glibenclamide), the negative group (only alloxan), and the treatment group (treated with sacha inchi leaf water extract) with different doses that is dosis dosis 0,26 g/kgBB, 0,525 g/kgBB, 0,525 g/kgBB (boiled water), 1,05 g/kgBB. Taking glucose and triglyceride data was checked 3 times within 10 days using a glucometer and lipid pro. The data analysis used the Analysis of Variance (ANOVA) method with the Statistical Package For Social Science (SPSS) Statistic IBM 23. This research began with testing of phytochemical compounds to determine secondary metabolism. Phytochemical test results with aqueous extract of Plukenetia Volubilis leaves contain tannins, alkaloids, saponins, and flavonoids. During 10 days of testing blood glucose and triglyceride levels on mice induced by alloxan, the effective dose was reduced on day 7 with a dose of 4 (1,05 g/kgBB). Based on the results of this research , it can be concluded that Plukenetia Volumbilis (Sacha Inchi) leaf water extract was detected to reduce blood glucose levels in mice and reduce blood triglyceride levels in mice for a certain time.
