Abstract

A flipbook with augmented reality based on ethnoscience, supported by Heyzine and Assembler, contains nanotechnology content for high school students. It is an interactive learning media in the form of an electronic book that contains photos, text, and animated content designed to assist students in learning the material through the visuals offered. Page flipping has a transition effect that helps students read each page and increases their learning use. Applied visual arts ethnoscience exemplifies the combination of community culture and science. Augmented reality is utilized to show objects in 3D and realistically related to the ethnoscience of applied fine arts in the Cirebon area, such as the scissor-grip home, megamendung batik, ceramics, masks, kujang, and paintings. The goal of this research is to develop digital teaching materials that can adjust to evolving technologies in order to increase educational quality. The data was collected using a quasi-experimental one-group pretest-posttest design for a total of 30 students, which was then processed using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) using descriptive statistics. This study found that students had good perceptions of the presence of a flipbook media with AR based on ethnoscience. Ethnoscience-based digital learning media can be used as interactive learning media because they provide precise visualizations of the concepts and conditions encountered during the learning process.

Abstract

The fabrication of slow-release urea fertilizer beads using chitosan and chitosan-biochar as coating materials has been accomplished. The beads were synthesized by solidifying chitosan-urea and chitosan-biochar-urea hydrogels in a NaOH solution. Characterization of the chitosan-urea composite beads (BKU) and chitosan-biochar-urea beads (BKBU) was conducted through Fourier-transform infrared (FTIR) spectroscopy, along with water intake (swelling) and nitrogen release tests in aqueous media at time intervals of 24, 72, 120, and 168 hours. The FTIR spectra of BKU and BKBU beads displayed functional group peaks associated with biochar (hydroxyl and carboxylate), chitosan (amine and hydroxyl), and urea (amine and carbonyl), along with others supporting group. Water intake rates were 72% for BKU and 81% for BKBU, which impacted nitrogen release patterns. BKU exhibited a faster nitrogen release compared to BKBU, indicating that BKBU is more suitable for use as a slow-release fertilizer due to its more gradual nitrogen release mechanism

Abstract

Although natural rubber has many good qualities, its commercial uses are limited by its low chemical reactivity and low heat stability. A derivative with better stability, Cyclic Natural Rubber (CNR), has to be chemically modified to increase its usefulness and broaden its range of applications. Investigating the effects of two different methods, the melt processing and solution system on the FTIR spectra of Cyclic Natural Rubber (CNR) graft copolymerization with Glycidyl Methacrylate (GMA) was the aim of this work. Additionally, an evaluation of the effect of Dicumyl Peroxide (DCP) and Benzoyl Peroxide (BPO) initiators on grafting results was carried out. According to FTIR spectrum analysis, the carbonyl ester (C=O) peak at roughly 1721 cm⁻¹, indicating effective grafting, was more pronounced in the melt processing approach than in the solution procedure. This implied that melt processing resulted in higher grafting efficiency. The absorption bands in the C-H stretching region (2860-2921 cm⁻¹) and the C=C stretching area (1672 cm⁻¹) show that the underlying structure of CNR has not degraded. The carbonyl index values for each composition showed that BPO performed better than DCP in the melt treatment method, however DCP as an initiator in the solution system produced a higher grafting efficiency than BPO.

Abstract

In dealing with the Merdeka Curriculum revisions, teachers must not only be capable and competent in developing instructional modules that match the needs of students. Teachers must also be able to apply them effectively during the learning process. This offers a big difficulty to teachers. This study intends to investigate the preparation of chemistry teachers and the challenges they confront when adopting teaching modules based on the Merdeka Curriculum. In this instance, numerous attempts can be taken to improve chemistry teachers' readiness to confront the issues they face. This form of research is descriptive and takes a qualitative approach. The data collecting subjects are three chemistry teachers from a senior high school in Banda Aceh City. The research data was obtained using semi-structured interviews. The data analysis technique uses the Miles and Huberman method. According to the study's findings, chemistry teachers are unprepared to adopt Merdeka Curriculum-based teaching modules. Teachers recognize the Merdeka Curriculum's essential concepts but lack confidence in constructing teaching modules on their own. Chemistry teachers face challenges in implementing teaching modules based on the Merdeka Curriculum, including a lack of training provided by schools to enhance teachers' understanding and skills regarding the structure and implementation of the independent curriculum in the chemistry learning process. To overcome this issue, schools could organize Merdeka Curriculum training or workshops to help teachers enhance their skills. Furthermore, the implementation of the Merdeka Curriculum demands efforts for coordination among teachers, school principals, and the school's educational office.

Abstract

The combination of D-mannose and D-glucose with β-1,4-glycosidic bonds with a ratio of 1.6:1 forms a straight chain polymer of glucomannan. Glucomannan flour is widely used in industry to make paper, adhesives, food ingredients, cosmetics, and cleaners. An organic mask preparation from glucomannan flour enriched with moringa leaf powder has been made from suweg tubers from Pidie Jaya, which is expected to be widely used, one of which is as a cosmetic ingredient. The purpose of this study was to determine the glucomannan content in suweg tubers from Pidie Jaya and to obtain the best formula of an organic mask based on panelist preferences. Glucomannan flour was extracted with 60% ethanol solvent and the glucomannan content test was carried out using the DNS method. The formulation of organic mask preparations includes glucomannan flour, moringa leaf powder, and H2O with different concentration ratios, namely F1 (50% glucomannan flour: 50% moringa leaf powder), F2 (75% glucomannan flour: 25% moringa leaf powder) and F3 (25% glucomannan flour: 75% moringa leaf powder). Then the physical properties were tested including pH test, homogeneity test, spreadability test, drying time test, and organoleptic test. The results of the study obtained a glucomannan content of 26.39%. The results of organoleptic testing showed that users preferred organic mask preparations from glucomannan flour enriched with moringa leaf powder formula F1 (50% glucomannan flour and 50% moringa leaf powder) both in terms of color, texture, odor/aroma, and general preference.

Abstract

The objective of this work is to enhance students' conceptual understanding by creating instructional materials based on the DARTs (Directed Activities Related to Texts) approach. The DARTs approach was selected because it may engage students in deep comprehension of scientific materials by assigning tasks including rearranging texts, filling in the blanks, and sequencing information. This study use the ADDIE model along with the research and development methodology. Thirty-five science education students enrolled in history and philosophy of science courses served as the study's subjects. Data collection instruments included concept understanding exams, student response questionnaires administered following instruction, and material and media expert validation questionnaires. According to the analysis's findings, the validator considered the instructional materials feasible in the following areas: the technical aspect received an average score of 3.6 with fairly good criteria, the construction aspect received an average score of 4 with a good category, and the didactic aspect received an average feasibility value of 3.9 with a good category. With very feasible criteria, the media expert's feasibility was 90%. The student response questionnaire yielded 94.05 in the material aspect, 91.22 in the presenting aspect, 92.29 in the graphics aspect, and 96.90 in the language aspect. The very practical category includes all four elements. The pretest and posttest were used to gauge the students' conceptual knowledge; the moderate criteria yielded an N-Gain score of 0.47. This demonstrates how incorporating DARTs approach into teaching materials for history and philosophy of science improves students' conceptual comprehension.
