Development of Plant Bioplastic Learning Media Equipped with QR Codes to Improve Students\u27 Understanding of Biodiversity Material
Get PDFIn the Merdeka Curriculum, students are required to explore knowledge and skills from their own experiences. So far, teachers have been using picture, video, and PowerPoint media. Students\u27 understanding of biodiversity is lacking because they do not have direct experience in classifying plants. Therefore, it is necessary to develop plant bioplastic media equipped with QR codes as an effort to improve students\u27 understanding. The purpose of this research is to analyze the validity, practicality, and effectiveness of plant bioplastic learning media equipped with QR codes. This research uses the Research and Development (R&D) method with the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The research was conducted at SMA N 1 Bawang in the Academic Year 2023/2024. The research design used during the implementation phase was the Non-Equivalent Pretest Posttest Control Group Design. The validity of the media and materials was determined using validation questionnaires. The practicality of the media was determined based on teacher and student response questionnaires. The effectiveness of the media was determined based on student test results and student worksheets. Validity and practicality were analyzed descriptively, while effectiveness was analyzed quantitatively. The results of the validator assessment stated that the plant bioplastic media was highly valid. Teachers found the media to be very practical, and all students rated the media as practical or very practical. The Mann-Whitney test revealed that the learning outcomes of the experimental class were significantly higher than those of the control class. The number of students with medium and high N-gain in the experimental class was greater than that in the control class, namely 59% > 39%. Plant bioplastic media equipped with QR codes is valid, practical, and effective in improving students\u27 understanding of biodiversity

The results of the study indicate that the feasibility of the E-Module, according to subject matter experts, is rated at 85.83% (very valid), media experts at 82.79% (very valid), and learning experts at 92.75% (very valid). Faculty responses achieved an average percentage of 91.72% (highly feasible). Student responses were divided into three stages: individual trials at 93.05% (highly feasible), small group trials at 89.58% (highly feasible), and large group trials at 91.97% (highly feasible). Based on the N-Gain test, a value of 0.69 was obtained, which falls into the moderate category. Therefore, the developed TPACK-based E-Module is deemed suitable and sufficiently effective for use as a learning medium for biology students
Antioxidant Candidates in Deep Eutectic Solvent Extract of Choline Chloride-Oxalic Acid from Sago Bark (Metroxylon sagu L. Rottb)
Get PDFWaste deposits from sago (Metroxylon sagu L. Rottb.) starch extraction from sago trunks in Palopo City, Luwu Regency, North Luwu Regency and East Luwu Regency which are part of the Tana Luwu region are quite abundant. Many studies on the utilization of liquid waste from this process have been published. In contrast, the utilization of solid waste has not been widely carried out. In addition, studies on the identification of compounds from the extraction of sago bark waste using environmentally friendly solvents such as deep eutectic solvent (DES) are still minimal. The DES used was DES Choline Chloride-Oxalic Acid with a mole ratio of 1:2. The success of DES synthesis was confirmed by FT-IR. Extraction was carried out using the sonication method for 30 minutes at 50 W, room temperature, with a ratio of 80 mesh sago bark to DES of 1:10 (g/ml). The extract was filtered with filter paper with a pore diameter of 2.5 µm. Screening of compounds in the filtrate through GC-MS analyses. DES was successfully synthesized while still showing the main functional groups. GC-MS analysis of the filtrate showed that there were 8.36% squalene-like compound; 5.37% n-hexadecanoic acid-like compound and other compounds (with solvent exception) contained ≤1%
Optimization of Barium Sulfate Crystal Control with Additives and Stirring using Response Surface Methodology
Get PDFKristal barium sulfat merupakan padatan kristal yang melekat kuat pada permukaan material, sehingga pertumbuhan kristal barium sulfat perlu dikendalikan. Beberapa cara untuk mengurangi pembentukan kristal barium sulfat adalah dengan menambahkan zat aditif dan mengatur kecepatan pengadukan serta waktu pencampuran. Pada penelitian ini, untuk menentukan variabel penambahan zat aditif, kecepatan dan waktu pencampuran menggunakan model Box Behnken Design dengan Response Surface Methodology. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi zat aditif ZnCl2 dengan beberapa konsentrasi zat aditif 0, 12, 24 ppm, kecepatan pengadukan 0, 240, 480 rpm dan waktu pencampuran 25, 75, 125 menit terhadap berat kristal barium sulfat yang diperoleh. BaSO4 3000 ppm terbentuk dengan mereaksikan antara larutan BaCl2 dengan Na2SO4 pada suhu 50ºC. Hasil penelitian menghasilkan model matematika yang dapat memprediksi kondisi optimum untuk perolehan berat kristal barium sulfat. Kondisi optimum yang diperoleh dari berat kristal barium sulfat adalah 0,22727 gram dengan konsentrasi ZnCl₂ sebesar 24 ppm, kecepatan pengadukan 48,48 rpm, dan waktu pencampuran selama 25 meni

Applying Augmented Reality in Color and Aesthetic Education: An Empirical Study on Enhancing Learning Outcomes of Students in a Five-Year Junior College Beauty Program
Get PDFThis study aimed to investigate the impact of integrating Augmented Reality (AR) technology into color and aesthetics education on the learning effectiveness of students enrolled in a five-year junior college beauty program. The research was conducted at a vocational college in northern Taiwan, targeting 58 first-year female students (aged 16–17) from the Department of Cosmetic Application and Management. All participants were enrolled in a required color and aesthetics course and had no prior experience using AR technology in educational settings, allowing for an objective assessment of AR as a novel instructional tool. A mixed-methods approach was adopted, combining paired-samples t-tests to analyze pre- and post-test data with qualitative methods such as student interviews and project work analysis. The results demonstrated that AR-created immersive and multisensory learning environments enabled students to visualize and simulate color combinations under varying lighting and material conditions, deepening their understanding of color theory and coordination. Moreover, the interactive features of AR fostered real-time collaboration and stimulated creative thinking and problem-solving. Compared to traditional teaching methods, AR-integrated instruction significantly enhanced students\u27 motivation, professional skill development, and overall satisfaction. These findings confirm the feasibility and pedagogical value of using AR in beauty education, offering both theoretical insights and practical evidence for its implementation in vocational and interdisciplinary curricula
