Abstract

AbstractCollaboration skills is one of the most important skills in the 21st century. Collaboration is an effort to achieve common goals that have been determined through the division of tasks / works, not as a work group but as a work unit, all of which are directed towards achieving the goals. This study aims to describe the collaboration skills of XI students at SMA Islam BAWARI Pontianak on reaction rate material. Indicators of collaboration skills are contributions, time management, problem solving and working with others. This research uses a descriptive method. The subject of the research was the XI grade students of SMA Islam BAWARI Pontianak in the academic year 2019/2020 which consisted of 35 students. The instrument used was the student collaboration skills assessment sheet and interview guidelines. The results show that the collaboration skills of XI grade students based on the categories of highly skilled, skilled, and moderately skilled skills are 31.4%, 40% and 28.6%. Each indicator show that the level of collaboration skills of contribution, time management, problem solving, and working with others are respectively 74.3% (skilled), 67.8% (skilled), 73.6% (skilled) and 71.4% (skilled).Keyword:  Collaboration Skills,  Contributions, Time Management, Problem Solving,  Working With Other

Abstract

This study aims to determine whether there is as significant difference achievement between those who are tought using Sikakimi Media and without between those who are tought using Sikakimi Media who are the topic structure material and to determine the effect size of Sikakimi on students achievement. To achievement the aims, a quasy experimental design was conducted to classes from populations which consists of four classes whwre choosen as samples though random sampling technique. The samples were X IPA 1 class as experimental group and X IPA 3 as countrol group. Acoording to research design, with classes were given a set of test before and after treatment. To achieve the first aim, data were tested using U-Man Whitney test and to achieve the second data were tested using glass test. Acoording to U-Man Whitney data analysis, probality velue was 0,001 which meant there was a significant difference in achievement between both classes. Acoording to glasses test, the effect size score was 0,76 which mean Sikakimi had 27,64% in the medium category.

Abstract

The purpose of this research is to describe the ability of scientific literacy junior high school students in natural science subjects. The methodology of this research is descriptive qualitative. The total of students who involved in this qualitative research from SMP Negeri 2 Pontianak and SMP Negeri 10 Pontianak are 124. The value of scientific literacy skill used written tests which are given to the students by multiple choice and essay tests. The answers of the students are analyzed by the aspects of scientific literacy. Based on the analysis, the average percentage results of each aspect of scientific literacy are content knowledge in explaining scientific phenomena (27.25%), procedural knowledge in interpreting data and evidence scientifically (53.34%), epistemic knowledge in interpreting data and evidence scientifically (17.4%), and epistemic knowledge in evaluating and designing scientific inquiry (33.23%). Based on the grades achieved by students, it is divided into three categories of grades, high, medium, low. Based on the results of research the average scientific literacy ability of students included in the low category with a percentage of 73.02%. This proves that a small proportion of students have scientific literacy skills.

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

The aims of this research were to determine the feasibility of Development Electronic Worksheet (e-worksheet) based on Project Based Learning on geometry molecule by the results of expert judgments and student responses on the results of field trials. The form of this research is research and development (R&D) which adopts Kemp's development model. The subject of this research was Electronic Worksheet (e-worksheet) based on Project Based Learning on geometry molecule which was tested at 27 students of SMAN 10 Pontianak. The instruments of data collections were the feasibility questionnaire and student response questionnaire. The results of data processing showed that the e-worksheet that developed was suitable for use in learning in terms of the percentage of content material, presentment, linguistic, and media respectively 96.6%; 96.8%; 90.2% and 86.1%. The result percentage of the calculation student questionnaire responses to the material aspects was 83.33%, 79.31%  to linguistic aspects and graphical aspects was 89.50%. Based on the average of the three aspects of student responses, it was found that the percentage of e-worksheet based on Project Based Learning on geometry molecule subject was 84.04%, which was included in the very high category.

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.
