Abstract

Natural antibiotics may offer a solution to the growing issue of pathogenic bacterial resistance caused by the widespread use of synthetic antibiotics. This study investigates the diversity and potential of Actinobacteria from the rhizosphere of Pinus in the Selorejo Bedengan Forest, Malang City, which has been exposed to synthetic agricultural chemicals for an extended period. Soil samples were collected and analyzed for various environmental factors, including pH, moisture, organic matter, and light intensity. A total of seven Actinobacteria isolates were identified, belonging to the genera Streptomyces and Nocardia. The diversity of these isolates was assessed using the Shannon-Wiener index, yielding a moderate diversity value (H' = 2.74). Antibacterial activity was tested against Escherichia coli and Shigella dysenteriae using the pitting method. The results indicated that isolates AC5 and AC7 exhibited inhibition zones of ≥11 mm and ≥12 mm, respectively, categorizing them as having strong antibacterial activity. These findings highlight the significant potential of local Actinobacteria as candidates for the production of natural antibacterial compounds to combat pathogenic bacteria. This research not only supports the development of more environmentally friendly antibiotic alternatives but also encourages the sustainable use of local microbial resources.

Abstract

The Waitatiri Watershed (DAS) in Central Maluku is one of the tropical ecosystems that supports biodiversity, including fungi and lichens. Fungi play a significant role in organic matter decomposition, while lichens serve as bioindicators of air and environmental quality. However, information regarding the diversity of these organisms in the Waitatiri watershed remains limited. This study employed purposive random sampling to explore fungi and lichens in the Waitatiri watershed. Samples were collected from substrates such as living tree trunks, deadwood, bark, rocks, and soil. Initial identification was conducted using digital applications, followed by detailed identification based on relevant scientific literature. Data were analyzed descriptively to describe species types, distribution, and ecological roles. The study identified 10 fungal species from the phylum Basidiomycota and 7 lichen species from the phylum Ascomycota were identified, with foliose thalli and crustose thalli growing on living tree trunks, dead bark, and rocks. The presence of crustose lichens indicates relatively good air quality in the region. The diversity of fungi and lichens in the Waitatiri watershed highlights its importance as a local biodiversity habitat. Their ecological roles as decomposers and environmental bioindicators emphasize the need for watershed ecosystem conservation to ensure environmental sustainability. Further research is required to explore the ecological and economic potential of the identified species and support conservation efforts.

Abstract

Galangal (Kaempferia galanga L.) is a medicinal plant known for its antimicrobial properties. Its rhizome contains bioactive compounds such as alkaloids, flavonoids, tannins, phenols, quinones, steroids, and triterpenoids, which have been reported to inhibit the growth of Staphylococcus epidermidis, Propionibacterium acnes, and Candida albicans. This study aimed to evaluate the antimicrobial activity of the ethanol extract of galangal rhizome from the Purbalingga accession. The antimicrobial activity was assessed using the disc diffusion method to determine the inhibition zone diameter (IZD), while the minimum inhibitory concentration (MIC) and minimum killing concentration (MKC) were determined using solid agar dilution. Extract concentrations of 10%, 30%, 50%, 70%, and 90% were tested for IZD. Clindamycin was used as a positive control for S. epidermidis and P. acnes, while nystatin was used for C. albicans; 10% DMSO served as the negative control. MIC values were evaluated at concentrations of 1.25%, 2.5%, 5%, and 10%. The ethanol extract inhibited the growth of S. epidermidis at a concentration of 10%, with an IZD of 8.38 mm. The inhibition zones for P. acnes and C. albicans were 8.42 mm and 9.24 mm, respectively. The MIC was 10% for S. epidermidis and 2.5% for both P. acnes and C. albicans. The MKC for P. acnes and C. albicans was determined to be 5%. The ethanol extract of K. galanga rhizome from the Purbalingga accession exhibits antimicrobial potential against S. epidermidis, P. acnes, and C. albicans, suggesting its potential use in antimicrobial applications

Abstract

This classroom action research was conducted in 2024 at SMA Negeri 42 Maluku Tengah, specifically in grade X Biology, focusing on the Plantae topic. The study was motivated by the low student engagement and learning outcomes, which were evident from several factors, including lack of enthusiasm during lessons, minimal participation in learning activities, the perceived irrelevance of the material to daily life, and overall poor academic performance. To address these issues, a combination of the Culturally Responsive Teaching (CRT) approach and the Role Playing model was implemented. This strategy aimed to enhance students' comprehension by connecting the material to real-world experiences, thereby improving their academic performance. Conducted in two cycles, the study revealed a significant improvement, with student motivation reaching 98% and learning outcomes achieving 100%. Students with higher motivation demonstrated better academic results as they were actively engaged in the learning process and could relate the material to their everyday experiences. The findings suggest that integrating the Culturally Responsive Teaching (CRT) approach with the Role Playing model effectively enhances student motivation and learning outcomes in Biology, particularly in the Plantae topic.

Abstract

Coastal areas have high biodiversity, which is essential in supporting sustainable development. However, low biodiversity literacy among coastal communities challenges conservation efforts and sustainable resource utilization. Reorienting interdisciplinary-based education is a necessary strategy to improve people's understanding of coastal ecosystems, including coral reefs, mangrove forests, and seagrass beds. Therefore, this paper aims to analyze the potential of coastal resources as a pillar of sustainable development, identify interdisciplinary approaches that can support biodiversity literacy, and design interdisciplinary strategies in reorienting education. Various scientific fields, such as Marine Science, Agricultural Science, Education Science, Social and Political Science, Legal Science, and Education Management science, can contribute to building a holistic and community-based educational approach. Knowledge in the form of local wisdom can support coastal area management. For example, the Sasi tradition in Maluku is vital in preserving marine biodiversity by regulating the sustainable use of natural resources according to the ecosystem cycle. Through synergies between academia, government, and communities, adaptive education programs can be implemented to equip communities with sustainable marine resource management skills. This approach is in line with the Sustainable Development Goals (SDGs), particularly goals 14 (Marine Ecosystems), 4 (Quality Education) and 13 (Addressing Climate Change). With proper policy support, education in coastal areas is expected to create an environmentally aware generation, adapt to global challenges, and actively preserve marine ecosystems for sustainable prosperity.

Abstract

Diseases caused by bacteria can usually be combated by administering antibiotics and using antiseptics. However, there are some groups of pathogens, such Escherichia coli as well as Staphylococcus aureus, which are highly resistant to the antibiotics amoxicillin, penicillin, tetracycline and chloramphenicol. One of the efforts to control these bacteria is by using bioactive compounds derived from plants. Banana plants contain secondary metabolite compounds flavonoids, saponins, and tannins that can act as anti-infective agents, including muli banana (Musa acuminata Linn.). Banana plant roots as natural ingredients can be an alternative to antiseptics because they contain antibacterial compounds with milder side effects than long-term use of alcohol-based antiseptics that can reduce skin moisture. This study was conducted to determine the efficacy of banana muli root extract (M. acuminata Linn.) as an antibiotic and antiseptic. The hypothesis in this study is that the root extract at a certain concentration is thought to have effectiveness as an antibiotic (E. coli) and antiseptic (S. aureus). In this study, the Kirby-Bauer method was applied by agar diffusion and the results of the inhibition zone test were formed around the paper disc. The results showed that the optimum efficacy of muli banana root extract (M. acuminata Linn.) as an antibiotic (E. coli ATCC 25922) was at a concentration of 95% (2.96 mm) and as an antiseptic (S. aureus ATCC 25923) at a concentration of 75% (9.1 mm).
