Abstract

Gunung Mutis National Park (TNGM), located in South Central Timor Regency, East Nusa Tenggara, contains a diverse range of highland herbaceous vegetation with the potential to be used as a learning resource. However, the lack of locally contextualized learning media poses challenges for Biology Education students in identifying herbaceous species during field studies. This research aims to develop an electronic atlas (e-atlas) based on herbaceous vegetation identification in TNGM as an interactive digital learning medium. This study employed the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), involving 25 students and 3 expert validators. Data were collected through validation questionnaires, learning outcome tests, student questionnaires, and lecturer reflections, then analyzed using descriptive quantitative methods. The results indicate that the e-atlas is valid in terms of content and design, practical in application, visually engaging, and effective in enhancing students' understanding of herbaceous species. A total of 12 species from 8 families were documented and included in the e-atlas, complete with scientific information. This e-atlas has the potential to serve as a contextual learning medium based on local resources, promoting ecological literacy and improving botany education in conservation areas.

Abstract

Biology education, particularly in the topic of biodiversity, faces challenges in improving student learning outcomes. One effective approach is problem-based learning (PBL), which promotes active student involvement in solving real-world problems. This study examines the impact of PBL on Student Learning Outcomes in biodiversity at the high school level. A quasi-experimental design was conducted at SMA Negeri 5, involving two classes selected through purposive sampling: an experimental class using PBL and a control class taught using conventional methods. Learning outcomes were assessed via pretests, posttests, N-Gain analysis, and ANCOVA. The results showed a significant improvement in the experimental class. The average pretest score for the experimental class was 45.63, while the posttest score increased to 80.1, resulting in an N-Gain of 0.37 (moderate). In contrast, the control class had a pretest score of 45.31 and a posttest score of 75, with an N-Gain of 0.49. Despite the control class showing a slightly higher N-Gain, the PBL model was more effective in improving learning outcomes, with 93.75% of students in the experimental class achieving mastery compared to 65.63% in the control class. ANCOVA results revealed a p-score of 0.002, confirming that PBL significantly enhances student learning outcomes.

Abstract

The utilization of lignocellulosic biomass as an alternative energy source and industrial material is still constrained by the limited availability of efficient cellulase-producing microorganisms. Mahogany forest soil, which contains leaf litter rich in cellulose, has the potential to serve as a habitat for cellulolytic bacteria with unique characteristics. This study aimed to isolate and characterize cellulolytic bacteria from mahogany forest soil in South Central Timor Regency, East Nusa Tenggara. The research employed an exploratory laboratory design with purposive sampling to collect soil samples beneath mahogany leaf litter at a depth of 0–20 cm. Bacterial isolation was conducted using the serial dilution method and cultivation on Carboxy Methyl Cellulose (CMC) medium. Characterization was performed based on colony morphology and Gram staining, while cellulolytic activity was assessed using the Congo Red method. Data were analyzed descriptively and quantitatively through colony counts using the plate count method and the determination of cellulolytic index values. The results revealed two bacterial isolates, namely AT1 (Gram-positive bacillus) and AT2 (Gram-positive coccus). Both isolates were able to produce clear zones, with cellulolytic indices of 1.96 and 1.26 mm, respectively. Isolate AT1 exhibited higher potential as a cellulase-producing bacterium. These findings highlight the potential of local cellulolytic bacteria as a promising source of cellulase enzymes for biotechnological applications.
