Abstract

Lettuce (Lactuca sativa L.) is a horticultural commodity with good commercial value. Lettuce production is insufficient for consumer needs because of the excessive use of inorganic fertilizers, which reduce soil fertility. This research aims to decide rhizobacteria in the rhizosphere of sugarcane roots and their influence on increasing the growth of lettuce plants. The methods used are observational methods for taking composite soil samples. Macroscopic observations of bacterial colonies include the shape, elevation, edges, and color of the colonies produced. Through gram staining and physiological tests, including catalase, motility, carbohydrate fermentation, and indole tests, performed microscopic character observations. Field tests as PGPR were carried out on lettuce plants with treatment P0, P1, P2 and P3. The parameters observed were plant height, number of leaves, wet weight, dry weight, and root length. Based on the results of the research, the PGPR of sugarcane roots has rhizobacteria such as Corynebacterium sp, Terrabacter, Saccharococcus, Aeromicrobium, Paracoccus, Ancylobacter, Planococcus, and Azotobacter. PGPR affects the growth of lettuce plants, especially on plant height, number of leaves, and root length. Treatment P3 (PGPR 7.5 ml/L) and treatment P1 (2.5 ml/L) obtained the best concentrations, yielding optimal results on all test parameters. Treatments P0 and P2 did not have a significant effect on the growth of lettuce plants.

Abstract

Education has undergone significant changes in modern times. Students are experiencing a decline in their thinking skills, particularly in the areas of creativity and critical thinking. This is due to the monotonous nature of their learning, which has resulted in less developed thinking patterns. The EDP model aims to improve creative problem-solving skills, equip students with the ability to overcome difficulties through careful planning, and encourage learning through failure. This study describes the B-ProDe TEct (Brainstorming, Problem Solving, Design Prototype, Try, Evaluate of Conflicts) learning model, which integrates Brain-Based Learning (BBL) principles into Engineering Design Process (EDP). The model has been demonstrated to enhance creative thinking skills and improve science learning outcomes in junior high school students. The study utilizes a mixed methods research approach, combining both quantitative and qualitative methods. This approach enables a more comprehensive analysis of the research question. The practicality scores from each school, derived from the feasibility test, were 87.08%, 83.25%, and 86.67% respectively, resulting in an overall average of 85.67%. The study evaluated the effectiveness of the B-Pro DeTEct learning model on a group of 30 students. The N-gain was 0.37 at the third session and 0.55 at the fourth session, with an average N-gain of 0.46. These results suggest a moderate increase in cognitive learning outcomes before and after using the model. The study concludes that the model is valid, practical, and successful in enhancing creative thinking skills.

Abstract

Cyclosorus parasiticus (L.) Farw. from Mount Gumitir dominates the understory ferns vegetation along the roadside of a pine-mixed coffee plantation. Previous studies reported the metabolite profile with the flavonoid and alkaloid content. Current observations based on morphological structure of the specimens collection indicated a high variations, therefor molecular identification was required to support the phylogenetic data of the species. The aim of the study was to identify the Cyclosorus parasiticus sample originate from Gumitir using DNA barcode. We used three primers, i.e. ribulose 1,5-biphosphate carboxylase (rbcL), maturase K (matK), and Internal transcribed spacer 2 (ITS2) for molecular identification. The result showed that Cyclosorus parasiticus from Gumitir has a highest similarity with Christella latipinna (NC070300) from China with a value of Percent Identities value of 99.11% based on the ITS2 marker. The rbcL data in this study might contribute to supporting the molecular genus concept from recent Thelypteridaceae phylogeny.
