Abstract

In the learning process, students have used various teaching materials, such as modules, printed books, and Student Worksheets (LKPD). In addition, the learning process is also supported by the application of the problem-based learning model. One of the materials studied in grade XII of high school is biotechnology innovation. In the material, teachers use a problem-based learning model. This research aims to produce a LKPD based on problem based learning on valid biotechnology innovation materials in phase F of high school/MA. This type of research is a development research using a 4D model which includes four stages, namely define, design, develop, and disseminate. However, in this study, the disseminate stage was not carried out. The research instrument is in the form of a validation sheet used to test the validity carried out by three validators. The results of the study showed that the validity test by biology lecturers and teachers obtained an average score of 84.84% which is included in the very valid category. Thus, it can be concluded that the LKPD based on problem-based learning on the biotechnology innovation material phase F SMA/MA developed, is feasible to use.

Abstract

The effect of light on stomata has been extensively studied, but studies that specifically observed the effect of light intensity on the size and number of stomata in monocot plants at the Sempaja Arboretum, Samarinda, are still very limited, including monocot plants, and have the potential to be a contextual learning resource for biology education in schools. The purpose of this study is to determine the effect of light intensity on the number and size of stomata in monocot plants in the Sempaja Arboretum. This research was carried out from February to May. This study used a Non-Factorial Group Random Design, with 3 different light intensities (morning, noon, and evening). Based on the results of statistical tests (ANOVA and Duncan's follow-up tests), not all species show statistically significant differences in size and number between times (morning, noon, evening). Some species such as Sri Rejeki (Aglonema sp) and Turmeric (Curcuma longa) show statistically insignificant changes. In other species such as Virginia Flower (Commelina virginica), Palm (Arenga pinnata), and Golden Ivory Betel (Epipremnum aureum), the difference in stomata size between times is more pronounced and significant.

Abstract

The development of the Industrial Revolution 5.0 requires students, particularly prospective biology teachers, to acquire 21st-century skills, including numeracy literacy, which serves as the foundation for critical thinking, analytical reasoning, and problem-solving. This study aims to analyze the numeracy literacy profile of Biology Education students based on the Minimum Competency Assessment (AKM). The research employed a quantitative descriptive method involving 88 first- and third-semester students of the Biology Education Study Program at the University of Timor, selected using purposive sampling. The research instrument consisted of a numeracy test that referred to the content, context, cognitive processes, and numeracy literacy levels of the AKM. The findings reveal that students’ numeracy literacy is still categorized as Requiring Special Intervention. This condition is influenced by memorization-oriented learning, low learning motivation, and limited integration of numeracy in biology instruction. These results highlight the importance of implementing innovative and contextual learning strategies integrated with numeracy literacy so that prospective biology teachers can not only meet the minimum AKM standards but also develop pedagogical competencies relevant to the challenges of the 21st century.

Abstract

This study aims to determine the mechanism of action, antibacterial activity, and effect of ethanol concentration of Chinese betel leaf extract (Peperomia pellucida) on the growth of Propionibacterium acnes. The method used was disc diffusion with 96% ethanol solvent as well as determination of the number of test bacteria through the cup counting method, with the absorbance value adjusted to the McFarland standard of 0.5. The concentration of the extracts tested was 10%, 20%, 30%, 40%, and 50%. The data was analyzed using the One Way ANOVA test with the help of SPSS. The results showed that the ethanol extract of betel leaves of china had antibacterial activity against Propionibacterium acnes, characterized by the formation of an inhibition zone. At 10% of the activity is moderate, while at the concentration of 20%, 30%, 40%, and 50% of the activity is moderate. Standard conformity tests show that McFarland Kit's standard solution (Himedia) has an absorbance value of approximately 0.08–0.1 at a wavelength of 625 nm. The suspension of the test bacteria that was diluted to the absorbance value resulted in a number of Propionibacterium acnes cells of 1.2 × 10^7 CFU/mL. This shows that the number of test bacterial cells used is not entirely the same as McFarland's standard solution of 0.5. Thus, the ethanol extract of betel leaves has the potential to be an antibacterial agent against Propionibacterium acnes.

Abstract

Microgreens are young plants harvested when they are 7–14 days old after planting (DAP) with a nutrient content 40 times higher than mature plants, especially vitamins and phytonutrients. This study aims to determine the effectiveness of various growing media on the growth of sunflower microgreens. The study used a Randomized Block Design (RBD) with one factor of growing media (M1: sandy soil, M2: charcoal husk, M3: cocopeat, M4: rockwool) and three replicates, then the sampling process on each thinwall was 10 plants. The observation data were analyzed using a one-way Analysis of Variance (ANOVA) test to determine the differences between treatments. If the ANOVA results showed significance (< 0.05), then a further Honest Significant Difference (HSD) test was conducted at a significance level of 5% to identify treatments that were significantly different. Comparisons between treatments were presented in bar graphs. The results showed that cocopeat growing media provided the best growth response with an average plant height of 13.53 cm and wet weight of 32.8 g, which was significantly superior to other media. The superiority of cocopeat is supported by its physical and chemical properties, which are able to retain moisture, provide nutrients, and support root development. Thus, cocopeat is recommended as an effective growing medium for sunflower microgreen production.

Abstract

The distribution of seagrass ecosystems along the coast of Pemenang District, North Lombok Regency, plays an important ecological and economic role. However, this ecosystem is vulnerable to damage due to human activities. The purpose of this study was to analyze the spatial distribution and extent of seagrass cover based on its cover density level. This study used remote sensing methods through the interpretation of Sentinel-2A images. The analysis process included image merging, image cropping, water column correction using the Lyzenga algorithm, image classification using supervised and unsupervised methods, and field validation at 60 observation points. The results showed that seagrass meadows were widespread along the coast and Gili islands (Gili Trawangan, Gili Meno, and Gili Air), with a total area of ​​685.26 ha. Seagrass cover density was classified into three categories, namely high (33.69%), medium (45.02%), and low (21.29%), with a mapping accuracy level of 73.33%. Based on the Decree of the Minister of Environment No. 200 of 2004, most seagrass meadows were categorized as damaged. Factors influencing this condition include domestic waste, tourism activities, ship anchors, human movement (madak), and turtle grazing activity. Seven seagrass species were identified, with Cymodocea rotundata being the most dominant. These findings emphasize the importance of regular monitoring and ongoing management to maintain the sustainability of seagrass ecosystems in the Pemenang coastal area.
