Colchicine Colchicine-Induced Phenotypic Alterations in Dendrobium 'Transient White Rika' and 'Florenza': Valuable Material for Genetics-Based Learning Modules
No full textThis study investigates the phenotypic alterations in Dendrobium 'Transient White Rika' (RKA) and 'Florenza' (FLO) orchids resulting from colchicine-induced polyploidy during in vitro cultivation. Colchicine, a known mitotic inhibitor, was applied at varying concentrations (0 ppm, 4000 ppm, 5000 ppm, 6000 ppm) to induce chromosome doubling and assess its impact on the vegetative and generative phases of the orchids. A factorial Randomized Block Design (RBD) was employed to analyze the effects of these treatments. The study revealed significant variations in leaf length and color, particularly at higher colchicine concentrations. Morphological changes were most pronounced at 6000 ppm, where the leaf length decreased, and flower morphology exhibited unique features compared to the control. The study also observed a reduction in stomatal density as colchicine concentration increased, correlating with an enlargement of leaf epidermal cells. These findings indicate that colchicine treatment can effectively induce phenotypic changes in Dendrobium orchids, contributing to the development of hybrids with superior ornamental qualities. However, the study also notes that the response to colchicine is variable, with certain parameters like the number of new shoots and leaf width not showing significant changes. The results underscore the potential of colchicine-induced polyploidy in orchid breeding, though further research is necessary to optimize treatment protocols and ensure the stability and viability of the resulting hybrids. These findings may serve as valuable material for genetics-based learning modules in biology.Penelitian ini menyelidiki perubahan fenotipik pada anggrek Dendrobium 'Transient White Rika' (RKA) dan 'Florenza' (FLO) akibat poliploidi yang diinduksi kolkisin selama budidaya in vitro. Colchicine, yang dikenal sebagai penghambat mitosis, diaplikasikan pada berbagai konsentrasi (0 ppm, 4000 ppm, 5000 ppm, 6000 ppm) untuk menginduksi penggandaan kromosom dan menilai dampaknya terhadap fase vegetatif dan generatif anggrek. Rancangan Acak Kelompok (RAK) faktorial digunakan untuk menganalisis pengaruh perlakuan ini. Studi ini mengungkapkan variasi yang signifikan pada panjang dan warna daun, terutama pada konsentrasi colchicine yang lebih tinggi. Perubahan morfologi paling menonjol pada 6000 ppm, dimana panjang daun berkurang, dan morfologi bunga menunjukkan ciri-ciri yang unik dibandingkan dengan kontrol. Studi ini juga mengamati penurunan kepadatan stomata seiring dengan peningkatan konsentrasi colchicine, berkorelasi dengan pembesaran sel epidermis daun. Temuan ini menunjukkan bahwa perlakuan kolkisin dapat secara efektif menginduksi perubahan fenotipik pada anggrek Dendrobium, sehingga berkontribusi terhadap pengembangan hibrida dengan kualitas hias yang unggul. Namun penelitian ini juga mencatat bahwa respons terhadap kolkisin bervariasi, dengan parameter tertentu seperti jumlah tunas baru dan lebar daun tidak menunjukkan perubahan signifikan. Hasil ini menggarisbawahi potensi poliploidi yang disebabkan oleh kolkisin dalam pemuliaan anggrek, meskipun penelitian lebih lanjut diperlukan untuk mengoptimalkan protokol pengobatan dan memastikan stabilitas dan kelangsungan hidup hibrida yang dihasilkan.

Tea Grounds and Coffee Grounds Support Sustainable Growth of Mustard Plants
No full textThe concept of organic farming is an effort to maintain optimal levels of environmentally friendly production. Therefore, this research aims to determine the effect of adding tea dregs and coffee dregs to compost media alone or mixed as additional nutrients on the growth of mustard greens (Brassica juncea L.). This research used a Completely Randomized Design (CRD) consisting of 4 treatments with 3 replications, namely compost without tea dregs and coffee dregs as control (P0). The research data were analyzed using Analysis of Variance (ANOVA) and Least Significant Difference Test (LSD) at a significance level of 5%. The results of the research obtained were that giving tea dregs and coffee dregs to the mustard plant planting medium obtained positive results. Single application of tea dregs had a significant effect on plant height (9.80 cm) and number of leaves (7.5). The treatment with tea dregs also had a significantly different effect from the control and other treatments. Meanwhile, coffee grounds alone contributed to a plant height of 7.1 cm and a number of leaves of 3.75, where the results obtained were not significantly different from the control and other treatments. However, overall, both single and mixed treatments had no significant effect on plant root length. The results of the ANOVA analysis for growth with the mustard plant height parameter obtained a value of Fcount of 4.496 > Ftable, namely 3.49, the parameter number of leaf blades Fcount 8.757 > Ftable, namely 3.49, and the root length parameter Fcount 0.367 < Ftable 3.49
Evaluation of Higher-Order Thinking Skills of Middle School Students on Vibration and Wave Topic Using Rasch Measurement
No full textHigher-order thinking skills (HOTS) are crucial in science education, yet students often struggle to master them, particularly in complex topics such as vibrations and waves. This study aimed to evaluate the HOTS performance of 165 eighth-grade students from five schools in Purbolinggo Sub-district, East Lampung, using a two-tier multiple-choice test analyzed through the Rasch Measurement Model. The test consisted of 12 items, each with a content question and a reasoning tier, adapted from Treagust (1988) and validated through expert judgment. Rasch analysis indicated that most students demonstrated low HOTS ability, especially in the creating domain (C6), involving generating novel ideas or solutions. In contrast, analyzing (C4) and evaluating (C5) were relatively easier but still reflected limited mastery. The highest difficulty appeared in questions requiring divergent thinking and complex synthesis. Item fit statistics showed good instrument validity (person reliability = 0.93; item reliability = 0.83). These findings highlight the importance of implementing learning strategies that foster creativity and synthesis, such as problem-based learning or project-based approaches. The study was limited to one geographic area, which may restrict generalizability. Future research should explore broader contexts and incorporate qualitative data to deepen understanding of HOTS development in science
