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

This research employed a research and development (R&D) form which refers to the stages of development according to Borg & Gall. The science literacy-based e-LKPD was tested to 9 students of SMPN 3 Pontianak in the initial trial. In the main trial, the e-LKPD was tested to 36 students from three schools which are SMPN 2 Pontianak, SMPN 3 Pontianak and SMPN 4 Pontianak. The instruments for data collection were the feasibility assessment sheet and students’ response questionnaire. The result of data analysis showed that e-LKPD in terms of content, presentation, language and media with 96.8%; 98.2%; 94.4%; and 88.8% respectively. All of these percentages are categorized as very high criteria. The averaged percentage of students’ response on the initial trial and the main trial are 81.6% and 83.9% which categorized as very high criteria. Therefore, e-LKPD is feasible to be used in learning projects based on science literacy on environment pollution topic.Keywords: Science literacy, project based learning.

Abstract

The aims of this research were to determine the difference of students learning outcomes using Sicetar (Siapa Cepat dan Benar) card media and to determine its effect toward student learning outcomes on solubility and solubility product constant for the eleventh grade students at SMA Negeri 10 Pontianak. This research used Quasi Experimental Design and cluster random sampling technique was use as research form and reasearch sample respectively. The instrument used are pretest, posttest, observation sheets and interview guidelines. Based on the posttest data analyses using U-Mann Whitney test, Sig values obtained at 0,001 < 0,05. The result showed that there is difference learning outcomes between students who were taught by using Sicetar card media in the solubility and solubility product constant with students who learn without using Sicetar card media. Sicetar card media gave effect  on student learning outcomes by 28,81%  and with Effect Size value of 0,81 in 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.
