Abstract

The reading and writing habits of SMAN 2 Percut Sei Tuan students are relatively low. Therefore, students' literacy and high order thinking abilities are also relatively low. The implementation of scientific literacy-based learning strategies in the form of making summaries at the end of the learning process is expected to improve students' literacy and high order thinking skills. The instruments used are tests in the form of varied multiple choices and essays totaling 8 and 2 questions. The results of data analysis show that students' initial abilities on the 9 of HOTs-Literacy indicators are very low with an average value of 28.49. The summarizing treatment at the end of the learning process succeeded in improving the ability of HOTs-Literacy students in indicators (1) identifying information and data, (2) using information and data, (3) producing explanatory models, (4) distinguishing questions that can be researched scientifically, (5) formulating hypotheses, (6) making predictions, (7) analyzing data, (8) interpreting data, (9) drawing or presenting conclusions, respectively 63.7 ; 66.7; 68.4 ; 64.0 ; 70.9 ; 70.8; 79.2 ; 81.4 and 86.3 %.

Abstract

Students' scientific literacy abilities are relatively low; apart from that, students are not yet accustomed to solving HOTS-based chemistry science literacy questions, especially in content, context, and science competency. This research aims to analyze the distribution of students' scientific literacy abilities in content, context, and competency. The instruments used are reasoned multiple-choice tests and essays. This research used quantitative descriptive research with a sample of all class XI Science students at SMA Negeri 2 Percut Sei Tuan for the 2023/2024 academic year. The results of data analysis show that the distribution of students' scientific literacy abilities in the content aspect is 71.33% in the content domain in the medium category, the procedural domain 57.11%, and the epistemic domain 56.99% in the low category. The distribution in the context aspect of the health domain was 66.08% in the medium category; the natural resources domain is 48.25%, and the environmental domain is 42.66%, which is in the deficient category. Moreover, the distribution in the domain competency aspect of explaining scientific phenomena is 55.13% in the low category; the domain of evaluating and designing investigations is 44.64%, and the domain of interpreting data and evidence scientifically is 46.68% in the deficient category.

Abstract

Many students do not have good problem solving skills in solving problems in everyday life, especially in chemistry learning. Therefore, analysis of students' problem solving abilities is needed to determine the level of problem solving abilities in chemistry learning, especially in colloidal systems material in everyday life. The purpose of this study is to describe how students use cooperative learning, specifically contextual learning, to solve problems. The goals of this study will be accomplished since the data collected will take the shape of words or utterances derived from the outcomes of interviews and Polya's problem-solving abilities. The use of this innovative learning media is supported by a contextual learning model. The type of research used in this study is qualitative research with a descriptive approach. This research procedure includes: (1) preparation stage; (2) implementation stage and (3) Final Stage. The problem solving ability of class XI students of SMAS Pertiwi Medan is at the "very good" level with a total of 24 students and a percentage of 39% of the total 62 students. The difficulty in answering problem solving ability test questions that students often experience is not understanding the story content of the test questions given.

Abstract

Polarity is an essential concept in chemistry, but many students struggle to grasp it, necessitating the use of a simple learning medium. This study aims to examine the polarity levels of extracts from ten imported fruits, including Fuji apple, kiwi, strawberry, Sunkist orange, grape, pear, date, blueberry, cherry, and dragon fruit, using a static electricity-based device. The device was created using simple materials, making it practical for use in chemistry lessons. Its working principle is based on the deflection of liquid droplets, which are influenced by static electric charges on mica. The results showed that most extracts experienced varying degrees of deflection. Strawberry, pear, and kiwi exhibited strong deflection due to the presence of polar compounds, while apple, cherry, and grape demonstrated moderate deflection. Blueberry could not be tested due to its high viscosity. This study presents a straightforward learning tool to help students better understand the polarity of covalent compounds, providing an accessible approach to learning complex chemistry concepts.

Abstract

In the 21st century, education is becoming increasingly important to ensure students have learning and innovation skills, skills in using information technology and media, and can work and survive using life skills. One of the life skills that students must have now is HOTs-literacy. This research aims to (1) to find out learning media used in learning process; (2) to design a prototype that will be developed to produce a learning media based on HOTs-literacy; (3) to find out whether the learning media that has been developed meets the criteria; (4) to find out student responses to the media. The method used in this research is 4D model. The result: Based 5 validators it was found 86.6% with a very high Percent Interpretation and a œEligible level of eligibility of the media and for the student responses get 95.71% with œvery interesting level. This shows that the HOTS-Literacy-based learning media using iSpring on acid-base material that has been developed is very attractive to students, so it can be used as a supporting medium in learning chemistry.

Abstract

The FSLC (Formulate Share Listen Create) model is a cooperative learning approach. This study compares the FSLC model with crossword media to a conventional PowerPoint-based model and examines the correlation between students' learning outcomes and interest. The sample included 25 purposively selected students per class for experimental and control groups with similar backgrounds. Using a pretest-posttest control group design, the experimental class learned electrolyte and nonelectrolyte solutions via FSLC with crossword puzzles, while the control class used PowerPoint. Results showed higher average interest (86.60 vs. 80.40) and outcomes (83.30 vs. 79.70) in the experimental group, with F_calculated > F_table. A strong correlation was found between interest and outcomes in the experimental class (r = 0.931 > r_table = 0.396), with a determination index of 11%, indicating a positive relationship.

Abstract

This research aims to compare the effectiveness of sulfuric acid and hydrochloric acid catalysts in the esterification of frankincense cinnamic acid (STYRAX paraleoncomud PERK). Esterification of sulfuric acid catalyst is carried out with ethanol and for hydrochloric acid catalyst with methanol. Esterification was carried out by refluxing a mixture of 1:20 cinnamic acid - ethanol and methanol, with 3 mL of each catalyst at a temperature of 60oC for one hour. The results were rinsed with 3 x 50 mL distilled water and dried with anhydrous sodium sulfate. The results were filtered and verified for functional groups using FTIR and composition analysis using GC “ MS. The results of FTIR interpretation show a decrease in absorption intensity (-OH) at 3500 cm-1 as a functional group that reacts compared to the ester results as an indication of the ongoing esterification reaction. The resulting ethyl cinnamate has a high conversion of 84.42%. Methyl cinnamate also has a distinctive ester aroma but is clearer and based on GC-MS, the content of methyl cinnamate is relatively low, namely 34.40%, the remaining cinnamic acid is 37.28%, and various side products of 28.32%. Thus, the catalyst that provides better conversion is sulfuric acid, but it requires further purification by examining the appropriate absorbent and bleaching agent. The brown color of the ester product catalyzed by sulfuric acid is thought to occur due to the oxidation of the cinnamic acid double bond by the catalyst.
