Abstract

Abstrak.Anggrek merupakan tanaman hias yang memiliki nilai ekonomi yang tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh dan konsentrasi optimal zat pengatur tumbuh (ZPT) 2,4-dichlorophenoxy acid (2,4-D) dan  Thidiazuron (TDZ) terhadap pertumbuhan tunas aksiler anggrek Dendrobium Red Emperor Prince. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor perlakuan yaitu konsentrasi 2,4-D dan TDZ ((0,0), (0,4), (0,5,3), (1,2), (1,5,1) dan (2,0)) dan posisi nodus (atas, tengah dan bawah) sebanyak 6 ulangan. Data dianailisis dengan menggunakan two-way ANOVA dan uji lanjut menggunakan DMRT 5%. Hasil penelitian menunjukan bahwa konsentrasi (0 ppm,4 ppm) mampu menginduksi tunas aksiler dan (1,5 ppm dan 1 ppm) mampu menginduksi akar anggrek Dendrobium Red Emperor Prince lebih baik. Kata kunci: 2,4-D, TDZ, induksi tunas aksiler, Dendrobium Red Emperor PrinceAbstract. Orchids are ornamental plants that have high economic value. This study aims to determine the effect and optimal concentration of plant growth regulators (ZPT) 2,4-dichlorophenoxy acid (2,4-D) and Thidiazuron (TDZ) on the growth of axillary shoots of the Dendrobium Red Emperor Prince orchid.

Abstract

This study investigates the integration of the traditional Goyang Karawang dance (GoKar) into biology education, particularly in teaching the human musculoskeletal system. Using a qualitative case study approach informed by ethnobiological and ethnopedagogical frameworks, data were collected through performance observations, interviews with dance artists and high school biology teachers, and document analysis. The analysis focused on the biomechanics and socio-cognitive meanings of core GoKar movements. Findings reveal that the dance involves coordinated actions of key muscle groups and joints, such as agonist-antagonist pairs and postural control centered in the hip and shoulder areas. Simultaneously, each movement expresses cultural values of grace, confidence, and balance, reflecting Sundanese philosophies of harmony. These embodied elements connect scientific anatomical knowledge with students’ lived cultural experiences. The research contributes to culturally responsive pedagogy by offering an experiential learning model that supports conceptual understanding while reinforcing local wisdom as a valid epistemic resource. This integration aligns with the goals of Indonesia’s Merdeka Curriculum and the Profile of Pancasila Students, promoting critical thinking, autonomy, and appreciation of cultural diversity. Overall, the study offers a transdisciplinary approach to science education that is inclusive, contextual, and pedagogically meaningful.

Abstract

This study aims to evaluate the effectiveness of the Science, Technology, Engineering, and Mathematics Project-Based Learning (STEM-PjBL) model in enhancing students' critical thinking skills through the contextual integration of bir pletok, a traditional beverage known for supporting digestive health. A systematic literature review (SLR) was conducted using the PRISMA 2020 protocol, analyzing 30 scientific articles that met defined inclusion criteria. The analysis revealed that STEM-PjBL significantly improves students' critical thinking, particularly in the domains of analysis, evaluation, and inference. Incorporating bir pletok as a learning context provided authentic, culturally relevant experiences that bridged scientific concepts with local wisdom. Key factors influencing learning success included the use of technology, personalized learning strategies, and the integration of indigenous knowledge. These findings contribute both theoretically and practically to the design of holistic and contextual 21st-century learning models that are sustainable and culturally responsive.

Abstract

Penelitian ini bertujuan untuk mengetahui respon kedelai varietas Deja 2 pada kondisi cekaman kekeringan dengan parameter akumulasi malondialdehid (MDA), kandungan katalase (CAT) dan struktur anatomi akar. Penelitian ini dilakukan dengan eksperimen melalui kultur in vitro biji menggunakan media ½ MS (Murashige & Skoog) yang diberi PEG (Polyethylene Glycol) 6000. Variabel bebas pada penelitian ini adalah konsentrasi PEG meliputi 0%; 2,5%; 5%; dan 7,5%. Variabel terikatnya adalah kuantitas akumulasi MDA, kandungan CAT dan karakter anatomis akar kedelai Deja 2. Variabel terkendali meliputi jenis dan cara penggunaan PEG, kondisi lingkungan, dan karakteristik benih yang digunakan. Pengujian MDA menggunakan metode dari Gechev dengan pembacaan spektrofotometer 532 nm dan 600 nm. Pengujian kandungan katalase dilakukan dengan metode Aebi dan Lester dengan pembacaan spektrofotometer 240 nm. Hasil penelitian menunjukkan bahwa akumulasi MDA meningkat seiring meningkatnya konsentrasi PEG sampai konsentrasi 5%, dan menurun pada konsentrasi 7,5%. Kandungan CAT juga meningkat bahkan sampai pada PEG 7,5%. Perlakuan PEG tidak memberikan pengaruh signifikan pada luas akar, panjang stele dan tebal korteks melainkan pada tebal struktur epidermisnya.

Abstract

Nowadays, the ability to think critically and motivation in learning is something that must be owned by students. One of the learning models that can improve both is learning cycle 7E combined with e-worksheet. The purpose of this research is to develop e-worksheet based on learning cycle 7E to improve critical thinking skills and learning motivation of grade XI high school students as seen from the results of feasibility and practicality tests. This research is a Research and Development (R&D) study with the ADDIE model which is applied until the development stage only. The feasibility of the product was assessed by one material expert lecturer and one media expert lecturer and the practicality of the product was assessed by 5 biology teachers. The results obtained based on the product quality assessment, obtained a value from a material expert lecturer with an ideal percentage of 83.9% in the feasible category, a media expert of 83.3% which is in the feasible category, and the results of the practicality test by the teacher obtained an average ideal percentage of 94.5%. Therefore, e-worksheet based on learning cycle 7E can be used to improve critical thinking skills and student learning motivation.

Abstract

Problem-solving ability is one of the higher-order thinking skills that students must possess, as it enables them to apply scientific knowledge to real-life situations. This study aimed to investigate the effect of problem-based learning (PBL), based on coastal abrasion cases, on improving students’ conceptual understanding and problem-solving ability. A quasi-experimental method with a pretest-posttest control group design was employed. The research was conducted in two classes: the experimental class used PBL, while the control class applied Discovery Learning. The sample consisted of 60 students. Instruments included tests designed to measure both conceptual understanding and problem-solving ability. Data were analysed using ANOVA. The results showed that the significance value was less than 0.05. This indicates that students who received PBL instruction achieved significantly higher scores in conceptual understanding and problem-solving ability than those taught using Discovery Learning. These findings suggest that PBL based on real-world issues, such as coastal abrasion, is effective in enhancing students’ scientific thinking and problem-solving skills
