Abstract

This study aims was determine the level of eligibility of Project Based Student Sheets (LKPD) on Electrolyte and Non-Electrolyte Solution Materials which are developed based on the results of expert assessments and students' responses based on the results of field trials. This form of research and development (R&D) adopts the Borg and Gall development model. The subjects of this study were project-based LKPD which were tested on 15 students in the initial field trials and 34 students in the main field trials, all of which were grade X students of SMA Muhammadiyah 1 Pontianak. Data collection instruments used were the questionnaire of eligibility and student questionnaire responses. The results of data processing showed that the LKPD that was developed was very feasible to use in learning in terms of the percentage of content, presentation, language and graphics worthiness of 94.4%; 97.8%; 86; and 83.9%. The results of the calculation of the percentage of questionnaire responses of students in the initial field trials was 81.7% and in the main field trials was 82.6%. This shows that the students' response to the Project Based LKPD on Electrolyte and Non-Electrolyte Solution Materials is included in the very high category.Keyword : LKPD, project based learning and Electrolyte and Non-Electrolyte Solution

Abstract

This research aimed to produce practical guiding products that are suitable for use and to know the students' responses to the products developed. Research & Development (R&D) was used as a form of research which was referred to the 4D model by Thiagarajan, but the implementation of the model just limited a 3D level. Subject tested the students of Chemistry Education FKIP Untan who had taken kinetics chemistry courses. Data collection tools used were validation sheets and student response questionnaires on the product developed. The results of the expert judgement obtained interpretation is very feasible in terms of aspects of content feasibility, presentation feasibility, linguistic feasibility, and graphic feasibility with consecutive total scores is 97%, 95%, 96%, and 96%. Students' responses to the results of small group trials were 81% with high interpretation and in large group, trials were 81% with very high interpretation.

Abstract

This study were aims to determine whether there are differences in learning outcomes of students before and after being taught using videoscribe media and  influence the using of videoscribe media on learning outcomes of students of atomic structure material class X IPA SMAN 2 Sungai Raya. This research is a pre-experimental study with One Group Pre-test and Post-test Design. The subjects in this study were class X IPA 2, amounting to 32 students. Normality test data of the initial test results and the final test using the Shapiro-Wilk test with sig values. test = 0.05 results in initial test scores not normally distributed with sig scores. 0.001 and the final test value is normally distributed, Sig is greater than 0.05 with a significance value of 0.223. Wilcoxon signed rank test results show that the Asymp.Sig. (2-tailed) value is less than 0.05, 0.000 <0.05. It can be said there is an increase in student learning outcomes after being given treatment. N-Gain calculation results obtained a value of 0.38 which shows learning using videoscribe media on atomic structure material gives an increase in the medium category in students.Keywords: videoscribe, learning outcomes, atomic structure

Abstract

Morus alba L species, usually known as mulberry, have a distinctive color, namely blackish purple. This color is caused by the presence of anthocyanin compounds which are color pigments. Anthocyanin compounds have the potential to be used as indicators of acid base. This study aims to determine the pH, solubility and shelf life trails of acid-base indicator films from chitosan-based mulberry fruit extracts. The method used is extraction by maceration, through immersion of mulberry fruit that has been refined using 96% ethanol solvent. Determination of the pH route using an acetate buffer solution with a pH of 1-14. The solubility of acid-base indicator film can be seen by immersing the indicator film in water for 24 hours, weighing it to a constant and comparing it to film that is not immersed in water and calculated the value of FS% (film solution). The shelf life of the indicator film was observed using a microscope to find out whether there was mold growth on the surface of the film. The results of the study showed that the pH of the acid-base indicator film strain of mulberry fruit extract, namely, pH 1-3 were red, and pH 10-14 were green. Based on data analysis, the percentage of the solubility of the acid-base indicator film of mulberry extract was 40.18%, which means that the indicator film with mulberry extract was hydrophilic so that it was easily dissolved in water compared to without the mulberry extract of 22.2% which had lower solubility values. Durability for 30 days was observed in the absence of growth of microorganisms / fungi on the surface of the indicator film.
