Abstract

Peatland ecosystems play a crucial role in maintaining the stability of the urban microclimate through the role of vegetation in regulating temperature, air humidity, and light intensity. This study aims to identify vegetation characteristics, analyze differences in microclimate conditions between peatland and non-peatland areas, and examine the relationship between vegetation characteristics and microclimate comfort in the city of Pekanbaru. The study was conducted at four stations: a protected peatland, a cultivated peatland, an urban forest, and an office district. The observed parameters included air temperature, relative humidity, light intensity, and Temperature Humidity Index (THI), while vegetation characteristics included diameter at height (DBH), tree height, and canopy area. Data analysis utilized the Importance Value Index (IVI), the Mann-Whitney U test, and Spearman’s correlation. The results showed that all sites had THI values in the “comfortable” category. Air temperature and relative humidity did not differ significantly between peatland and non-peatland areas, whereas light intensity differed significantly . Canopy area showed a strong but non-significant negative relationship with light intensity , indicating that larger canopy tends to reduce surface light intensity. These results suggest that vegetation, particularly canopy area, plays an important role in maintaining microclimate conditions and urban thermal comfort in Pekanbaru, even though the statistical relationship is not yet significant.

Abstract

Fern morphology is commonly taught using printed textbooks and static two-dimensional images, which limits students’ understanding of its three-dimensional structures, especially given the limited availability of real specimens in schools. The primary objective of this study was to develop a learning media utilizing Augmented Reality (AR) in a flipbook format focused on fern morphology, designed to support students’ learning interest in fern morphology. We employed a Research and Development (R&D) methodology guided by the ADDIE framework: analysis, design, development, implementation, and evaluation. This process produced FLORAVIA, an interactive AR-based flipbook that lets learners view realistic 3D models of fern structures on their smartphones. Participants consisted of one biology teacher and 35 eleventh-grade science students (Class XI IPA 1) at SMA Negeri 12 Surabaya. Data were collected through feedback questionnaires for the teacher and students, while media and subject-matter experts assessed the product using standardized validation sheets, and the data were analyzed descriptively to determine validity and practicality. FLORAVIA achieved a validity score of 85% from the subject-matter expert and 100% from the media expert, both categorized as valid. Furthermore, feedback from the student responses indicated that the media was categorized as practical to highly practical, with users praising its visual appeal, interactivity, and ease of navigation. These results indicate that the AR-based flipbook is a valid and practical resource for biology instruction. Its effect on students’ learning interest and conceptual understanding was not tested and should be examined in further experimental research.

Abstract

The Ijen Geopark area specifically Gombengsari Urban Village is a coffee production hub that generates organic waste (such as leaves, beans, husks, dried stems, and flowers) that has not been effectively utilized as an educational resource. Limited student knowledge regarding conservation and environmental law, combined with the constraints of traditional teaching methods, has driven innovation in digital technology-based learning media. This study aimed to develop an Augmented Reality (AR) Digital Herbarium of Coffee Plants utilizing organic waste in the form of QR-coded keychains to enhance understanding of conservation and environmental law. The research employed the ADDIE R&D model and a quasi-experimental design. Data were collected through expert validation, questionnaires, observation, and pre-and post-tests, then analyzed using the N-Gain score. Verification by media experts yielded a score of 90.48% (highly valid), while verification by educational practitioners reached 80% (feasible). Conservation literacy scores rose from 55.81 to 81.69 (N-Gain 0.57), and environmental law literacy scores increased from 55.13 to 83.88 (N-Gain 0.62); both improvements fell within the moderate category. The AR Digital Herbarium of Coffee Plants serves as a feasible and reasonably effective contextual learning tool, integrating biology, conservation, environmental law, and the utilization of organic waste.

Abstract

The maleo bird (Macrocephalon maleo) is a species endemic to Sulawesi that is threatened with extinction due to habitat destruction and natural predation pressure. The Hungayono area within Bogani Nani Wartabone National Park serves as a crucial nesting habitat for the maleo, yet current population data remain limited. This study aimed to monitor the maleo population and analyze the factors influencing it in the Hungayono area. Research was conducted over  days between August and September , employing both direct (visual) and indirect (vocalizations and tracks) observation methods using the concentration count technique across two habitat types: nesting grounds and roosting sites. Data were analyzed using descriptive quantitative methods to calculate population density and estimate the total number of individuals. The study identified 84 pairs of maleo birds ( individuals) engaged in nesting activities, with a peak population density of  individuals/ha. Observed natural predators included monitor lizards (Varanus salvator) and spotted doves (Spilopelia chinensis), with frequencies of  and individuals, respectively. Key factors influencing the population included the availability of nesting habitat, predation pressure, climatic disturbances, and vegetation conditions. Even though the threat posed by predators is quite significant. The study concludes that the Hungayono area remains a vital reproductive habitat; however, predator management and continuous monitoring are essential to ensure the long-term survival of the maleo population.

Abstract

Environmental pollution caused by heavy metals such as chromium is found in various industrial activities, including the leather tanning industry. One approach to address such pollution is bioremediation using microorganisms. In its application, microorganisms must undergo detailed taxonomic identification to the species level to minimize competition among bacterial strains. This study aimed to investigate the biochemical characteristics, molecular identities, and growth responses of bacterial isolates under chromium stress. An experimental method with a descriptive quantitative design was employed. Four bacterial isolates from heavy-metal-contaminated rhizosphere soil were identified through biochemical tests, 16S rRNA gene analysis, and growth observation. Data were analyzed using the Man-Whitney U test to determine whether Cr(VI) stress significantly affected the growth of the isolates. The results identified four Bacillales isolates: Bacillus sp., Bacillus licheniformis, Bacillus paralicheniformis, and Brevibacillus borstelensis. All isolates grew at 500 ppm, while B. paralicheniformis grew at concentrations up to 1000 ppm. This study provides information on the potential of rhizosphere bacteria as bioremediation agents for chromium-contaminated environments.

Abstract

Microbial resistance to antibiotics in skin infections has created a need for new sources of antibacterial compounds. Physalis angulata L. leaves contain various bioactive compounds, making them potential source of endophytic bacteria capable of producing antimicrobial substances. This study aimed to isolate, characterize, and identify the bioactive compounds produced by endophytic bacteria from ciplukan leaves and evaluate their antimicrobial activity. Methods included direct plating for isolation, phenotypic characterization, and antimicrobial testing of single isolates and combinations of endophytic bacteria against Staphylococcus aureus, Cutibacterium acnes, Pseudomonas aeruginosa, Escherichia coli, dan Candida albicans. Bioactive compounds were identified using Gas Chromatography–Mass Spectrometry (GC-MS). Six endophytic bacterial isolates were obtained. The bacterial consortium supernatant produced larger inhibition zones than single isolates, showing the highest activity against C. acnes (13.9 mm), S. aureus (13.6 mm), E. coli (10.6 mm), and P. aeruginosa (9.8 mm). GC-MS analysis identified Bis(2-ethylhexyl) phthalate (39.33%) and 1,4-Benzenedicarboxylic acid, bis(2-ethylhexyl) ester (11.25%) as the dominant compounds likely responsible for the antimicrobial activity. These results indicate that endophytic bacteria from ciplukan leaves have potential as natural antibacterial agents. This study contributes scientific knowledge that can serve as a basis for developing natural antibacterial compounds derived from ciplukan leaf endophytic bacteria.

Abstract

This research is motivated by students' inability to present learning outcomes and their lack of active participation in biology classes. This study aims to determine the effect of the Search, Solve, Create, and Share (SSCS) learning model on the visual representation ability and collaboration skills of 11th-grade students. The quantitative method used a Quasi-Experimental Design with a pretest-posttest control group. The population included all 11th-grade students at SMA Negeri 01 Blambangan Umpu. The sample, selected via Cluster Random Sampling, was divided into experimental and control classes. Data were collected using essay tests for visual representation ability on the immune system, alongside observation sheets and questionnaires for collaboration skills. Data analysis was conducted using the Multivariate Analysis of Variance (MANOVA) test. The results showed a significance value of 0.000, concluding that the SSCS model significantly affects students' visual representation and collaboration skills. The implication of this research provides a practical contribution to the development of science by offering an effective innovative learning model reference to optimize students' cognitive and social competencies.

Abstract

Staphylococcus aureus is a pathogenic bacterium that causes skin infections and can be transmitted via the hands; therefore, antiseptic soaps containing natural active ingredients are needed as alternatives to synthetic antibacterial agents. Kedoya leaves (Dysoxylum gaudichaudianum) contain flavonoids, alkaloids, tannins, and steroids with antibacterial potential, but their use in liquid soap formulations has not been widely studied. This laboratory experimental study aimed to formulate a hand antiseptic liquid soap containing ethanolic kedoya leaf extract at concentrations of 0.5%, 1%, and 2%, and to evaluate its physical quality and antibacterial activity against S. aureus, using a soap base without extract as the negative control and Dettol liquid soap as the positive control. Physical quality was assessed by organoleptic, foam height, and pH tests, while antibacterial activity was determined by the disc diffusion method and analyzed using one-way ANOVA followed by the LSD test. All formulas met the SNI 06-4085-1996 requirements (foam height 67–72 mm; pH 8.8–8.9). The inhibition zone increased with extract concentration: 15.3 mm (0.5%), 18.7 mm (1%), and 20.6 mm (2%), with significant differences among concentrations (p < 0.05). According to the Davis and Stout criteria, the 0.5% and 1% formulas showed strong inhibition, whereas the 2% formula showed very strong inhibition, although still lower than the positive control (25.2 mm). This study provides initial evidence that kedoya leaves, a local plant of Southeast Sulawesi, can be developed as a natural antibacterial active ingredient in hand antiseptic liquid soap, with the 2% formula being the most promising for further development.

Abstract

Cow manure is a livestock waste product with high lignocellulose content that poses a potential environmental pollution risk if not managed properly. This study aimed to determine the effect of adding bioactivators, specifically cellulolytic fungal isolates (Penicillium sp. and Curvularia sp.), Aspergillus sp., and EM4 on the quality of compost made from cow manure and rice husks over a 35-day composting period. A Completely Randomized Design (CRD) was employed with five treatments and four replicates: P0 (control without bioactivator), P1 (EM4), P2 (Aspergillus sp. + FS2 + FS3), P3 (Aspergillus sp.), and P4 (EM4 + FS2 + FS3). Parameters observed included physical and chemical parameters. The results obtained were analyzed using analysis of variance (ANOVA). The results indicated that the addition of bioactivators accelerated the decomposition process and produced compost with superior physical characteristics compared to the control. Treatment P2 yielded the best physical quality compost, characterized by the finest, most crumbly texture and a uniform black color. Chemically, all treatments met the SNI 19-7030-2004 standards; notably, P0 exhibited the highest N content (1.60%) and the lowest C/N ratio (16.96), indicating optimal chemical maturity. This is likely attributed to the indigenous microorganisms in the cow manure being already optimally adapted to the substrate, thereby eliminating the need for an additional acclimatization phase.
