Abstract

The implementation of Merdeka curriculum has not long been established as the national curriculum, so many schools still lack teaching materials with limited textbooks.  This research aimed at developing STREAM (Science, Technology, Religion, Engineering, Art, and Mathematics) based Pancasila student profile strengthening project module on Chemical Bond lesson, and it was conducted with validity test by media and material experts, teacher practicality test, and student response test.  Research and Development (RnD) method was used in this research with Design and Development Research (DDR).  This research was conducted at State Senior High Schools 14 and 1 Pekanbaru.  The research findings showed that the validity scores were 82.6% by media experts with very valid category and 87.45% by material experts with very valid category.  The result of teacher practicality test showed that the mean was 93.84%, and it was on very practical category.  The last test was student response test, the result was 83.58%, and it was on very valid category.  The research findings showed that STREAM-based P5 teaching module developed was very valid, practical, and interesting for students.

Abstract

Misconceptions about ionic bonding bond and related concept have been revealed by many studies. One source of student misconceptions is high school chemistry textbooks. This research aims to analyze the ionic bonding conceptions contained in Class X high school chemistry textbooks in the city of Pekanbaru. This research uses document analysis techniques. The research sample was 5 high school chemistry books for class X in Pekanbaru City. Misconception are grouped according to Hershey (2004), namely Oversimplifications, Overgeneralizations, Obsolete Concepts and Terms, Misidentifications, and Flawed Research. Most textbooks suffer from Overgeneralizations of the concepts of  chemical stability, ionic bonds, and properties of ionic compound.

Abstract

Chemistry learning oriented to local natural resources around students presents real situations that can help students to understand the concepts of learning material being studied. This research aims to identify the chemical concepts involved in the process of palm oil production for developing contextual chemistry learning materials based on local natural resources. This research used descriptive quantitative research. Data were collected from field observation, literature study and documentation study. The relevance of chemical concepts and the context of palm oil processing were assessed by the validators. Based on the finding, there are 3 chemical concepts related to the palm fruit processing into crude palm oil (CPO), namely: classification of matter,change of matter, and separation of mixture. The relationship between both of these three chemical concepts and the context of palm oil processing has been declared highly valid with a score of 3.75 by the validators. Therefore, the processing of palm fruit into CPO can be used as a learning resource for contextual chemistry learning material in the implementation of Merdeka curriculum at phase E.

Abstract

The purpose of this study was to describe the effect of POE (Predict, Observe, and Explain) learning model on: 1) self efficacy, 2) student learning outcomes, and 3) self efficacy and student learning outcomes on basic laws of chemistry. This study used a quantitative approach with an experimental design of the quasi-experiment type, and with a non-equivalent control group design. The population in this study were class X students of SMAN 1 Ngunut, while the samples were class X-E as the experimental class and class X-F as the control class with the sampling technique was purposive sampling. The research instrument in the form of a questionnaire was used to measure student self-efficacy and test questions were used to measure student learning outcomes. Data analysis used prerequisite tests (normality test and homogeneity test), and hypothesis tests use independent sample t-test and manova test. The results showed that: 1) there is an effect of the POE learning model on self-efficacy with a sig value. (2-tailed) 0.000 <0.05, 2) there is an effect of the POE learning model on student learning outcomes with a sig value. (2-tailed) 0.000 <0.05, and 3) there is an effect of the POE learning model on self efficacy and student learning outcomes on the material of basic laws of chemistry with a sig value. (2-tailed) 0.000 <0.05.

Abstract

Pterocarpus indicus is a tropical wood type containing tannin compounds which potentially to be used as biomordants in woven fabrics dyeing. This research is the first work to determine the color cha racteristics of Timorese woven fabric after using tannin from Pterocarpus indicus bark as a biomordant. This research aims to determine the tannin content and colour properties of Timor woven fabric after using tannin as a a natural mordant. Pterocarpus indicus bark samples were prepared and extracted via hot extraction. The tannins in Pterocarpus indicus stem bark were qualitatively and quantitatively analyzed using FT-IR and UV-Vis Spectrophotometer respectively, then applied as a color binder for woven threads. The color properties of woven fabrics with tannin were compared to woven fabrics treated with Al2(SO4)3 mordant at a concentration of 15%. Color fastness to washing are tested using the Staining Scale Standard. Pterocarpus indicus bark tannin is a brown powder. Qualitative and quantitative tests show that Pterocarpus indicus bark contains tannins with a total concentration of 0.0436%. FTIR spectra exhibited functional groups absorption by the aromatic C-H, O-H, C=C, C-C, C-O-C, and C-O. The use of 15% tannin and curcumin dye produces a yellow-brown woven fabric with a fairly good color fastness value to washing. Pterocarpus indicus bark contains tannin which has potential as a biomordant for natural Timorese weaving dyeing.

Abstract

Teachers experience difficulties in designing teaching modules in the independent curriculum and teachers need differentiated teaching modules. This research aims to develop an Merdeka Curriculum Teaching Module Based on Problem Based Learning on Acid and Base Material and determine the feasibility of the teaching module and the teacher's response to the teaching module. The research method used is Research and Development (R&D) with the ADDIE model limited to the development stage. The subject of this research is the Independent Curriculum teaching module based on Problem Based Learning on acid base material. The research instrument used was a questionnaire. This questionnaire is used to validate the product and test teacher responses using a Likert scale. The data collection technique used was indirect communication techniques by providing questionnaires. Data from product validation results were analyzed using Gregory with validation results from the material aspect of 1 and the media aspect of 1 with the high validity category. Then a trial was carried out with a response test carried out on 2 chemistry teachers. The teacher response test results obtained a percentage of 100%. This shows that the Merdeka Curriculum teaching module based on problem-based learning on acid-base material meets appropriate for use as a teaching tool.

Abstract

The purpose of this research is to produce an Alare application that is feasible to use to train students' critical thinking skills in the sub-material of factors that affect the reaction rate. The feasibility of the Alare application is reviewed from three aspects, namely validity, practicality, and effectiveness. This research used the Research and Development (R&D) method with the Sukmadinata development model. The limited trial was conducted in class XI IPAS of Senior High School 20 Surabaya with 16 students. The research data shows that (1) Alare application is declared valid as indicated by the mode of content validity and construct validity of 4 with the valid category, (2) Alare application is declared practical as indicated by the average results of student response questionnaires, which are supported by student activity observations, amounting to 89.2% with very practical criteria, (3) Alare application is declared effective based on the increase in the acquisition of pretest and posttest scores of critical thinking skills and also the completeness of students' learning outcomes. The value of students' critical thinking skills based on the N-gain score increased because the medium-g and high-g criteria were obtained. The completeness of students' learning outcomes in both individual and classical completeness is significantly complete with a percentage of 100%. Based on this, it can be concluded that the Alare application is feasible to use to train students' critical thinking skills on reaction rate material.
