Abstract

This study addresses a persistent gap in science education—the limited integration of spiritual values and environmental stewardship into classroom practice. The research investigates how Project-Based Learning (PjBL) can promote students’ eco-literacy attitudes within the framework of Islamic science education. Employing a library research design and content analysis, the study examines books, journals, and related scholarly works focusing on PjBL, eco-literacy, and Islamic educational values. The findings reveal that PjBL enhances conceptual understanding and fosters active, contextual, and ethically informed scientific inquiry guided by Islamic principles. It also promotes eco-literacy through three interrelated dimensions: cognitive (knowledge of ecological systems), affective (concern for nature), and conative (environmental responsibility and action). The study concludes that integrating PjBL with Islamic values provides a coherent pedagogical framework that strengthens students’ scientific, moral, and ecological competencies. This approach is recommended for Islamic higher education institutions seeking to develop educators who are scientifically proficient, environmentally aware, and spiritually grounded

Abstract

Actinomycetes show promise as biological control agents, reducing fungicide use in agriculture due to their bioactive compounds and ecological resilience. This study focused on the initial screening and ecological bioprospecting of actinomycetes from the Hungayono karst ecosystem in Gorontalo by determining their antagonistic activity against the pathogenic fungi Fusarium oxysporum and Neocosmospora solani, as well as their tolerance to the fungicides thiram and benomyl. Potential isolates were identified using molecular methods. Samples were collected from three locations. Rhizosphere soil samples were obtained from plant species: Alocasia macrorrhizos, Ficus microcarpa, and Acrostichum aureum L. Antagonistic activity against root-pathogenic fungi and tolerance to fungicides were used as initial screening criteria to assess their potential as biological control agents. This study successfully isolated 9 actinomycete isolates. The results showed that only 33% of the isolates exhibited inhibitory activity, with isolate RzAH-07 showing a moderate inhibition zone (5.22 mm) against Fusarium oxysporum and weak inhibition (4.18 mm) against Neocosmospora solani, while also demonstrating tolerance to the fungicide benomyl up to 1000 ppm. RzAH-07 was selected as the top candidate due to its two key advantages. Phylogenetic analysis based on 16S rRNA gene sequences indicates that RzAH-07 is closely related to the genus Streptomyces, with a similarity percentage ranging from 98.35% to 99.14% based on GenBank data.

Abstract

Actinomycetes are soil microorganisms that play a crucial role in nutrient cycles and interactions, particularly in nutrient-limited environments such as karst ecosystems. This study aimed to evaluate the preliminary functional potential of actinomycetes isolated from the plant rhizosphere in the Hungayono karst ecosystem, Gorontalo, as phosphate solubilizers and producers of indole acetic acid (IAA). The study employed a quantitative descriptive approach with soil sampling at a depth of 10–15 cm using purposive sampling. Isolation was performed using the spread plate method on Starch Casein Agar medium, followed by qualitative and quantitative testing of phosphate solubilization and IAA production capabilities. Identification of selected isolates was conducted through 16S rRNA gene-based phylogenetic analysis. The results showed that 11 actinomycete isolates were obtained from 4 host plants, of which two isolates exhibited low-index qualitative phosphate solubilization activity. However, quantitative results indicated that some isolates that did not form clear zones still produced measurable amounts of soluble phosphate, suggesting differences in method sensitivity. The highest phosphate-solubilizing activity was exhibited by isolate RzPO-09. In addition, four isolates were capable of producing IAA at varying levels, with the highest production observed in isolate RzPH-07 at 0.896 ppm. Phylogenetic analysis showed that isolate RzPO-09 (PZ458677) is closely related to the genus Pseudonocardia, while RzPH-07 (PZ458434) is closely related to the genus Streptomyces. Overall, the isolates obtained show initial functional potential; however, further validation is required through optimization of culture conditions, genetic characterization, plant growth tests, and testing both in greenhouses and in the field to ensure their practical feasibility.

Abstract

Background: This research was initiated in response to the noticeable lack of environmental awareness among students in coastal regions, despite the area's abundant natural resources, and the absence of innovative, contextually relevant science learning tools. The research aims to develop a digital edutourism-based e-module at Kilo 5 Beach in Luwuk, designed to enhance students' conceptual understanding and foster environmental appreciation. Methodology: The research employs a Research and Development (R&D) approach, specifically the 4D development model (define, design, develop, and disseminate), though only three stages were executed: a preliminary study, design and validation by subject matter and media experts, and effectiveness testing with educators and students. Effectiveness was evaluated using pre- and post-tests, with data analyzed through the N-Gain formula and t-tests. Findings: This e-module is validated as educational resource. Expert validation confirmed the e-module's validity, with average scores exceeding 9%, indicating no revisions were needed. Practicality assessments revealed positive feedback from both teachers and students, with scores in the excellent category (above 90%), demonstrating the e-module's high practicality. The e-module's effectiveness was further evidenced by an increase in students' understanding, reflected in an N-Gain value of 0.6316 (medium category) and a significant t-test result (0.00<0.05). Contributions: This research provides empirical support for the use of educational tourism–based e-modules as contextual digital learning tools to improve environmental awareness and conceptual understanding among coastal junior high school students. It advances the 4D development framework by embedding local ecotourism contexts into science learning materials and evaluating their validity, practicality, and learning impact. The findings offer a transferable instructional approach that links formal science education with local environmental resources to support place-based and sustainability-focused learning.

Abstract

Several pathogenic bacteria such as Staphylococcus aureus, Escherichia, Pseudomonas aeruginosa and other pathogenic bacteria have developed resistance to many marketed antibiotics. Staphylococcus aureus is already resistant to several types of antibiotics such as penicillin, erythromycin, cefoxitin, levofloxacin, and clindamycin, Escherichia is resistant to several antibiotics such as Penicillin G, Cefotaxime, Tetracycline, Ampicillin, and Amoxicillin, Pseudomonas aeruginosa has been resistant to antibiotics that target ribosomes, such as tobramycin and tigecycline. The problem of resistance of several pathogenic bacteria can be overcome by finding new metabolite compounds from Actinomycetes microorganisms that have antibiotic potential by exploring extreme areas, one of which is in the karst area, especially in plant roots. Root sampling was carried out by taking samples + 20 cm on each type of plant found. Isolation of Actinomycetes bacteria was carried out using the plate method. Antibacterial activity testing was carried out using the line method. The morphological form of the spores was seen using a SEM (Scanning Electron Microscope). The results of the study found 2 isolates of isolated plant roots containing Actinomycetes bacteria. 2 isolates showed morphological characteristics of mycelium, oval and round in shape and had various colors. The results of the antibacterial activity test showed that each isolate could inhibit several types of pathogenic bacteria, seen from the clear zone with different diameters and the results of SEM (Scanning Electron Microscopy) showed that 2 isolates had the same character and shape of spores as Actinomycetes, namely the genus Streptomyces.

Abstract

This study focuses on observing the structure of mangrove vegetation in Popalo Village, North Gorontalo Regency. Scientists found that the condition of mangrove forests in the area is not uniform, with some areas still well maintained, especially near rivers and beaches, while other areas, especially near settlements, have been damaged due to land conversion into ponds. This type of research is descriptive quantitative using a survey method. The most dominant type of mangrove found is Rhizophora. In addition, this study also shows that environmental factors such as temperature, air acidity, and salt levels greatly affect the growth and development of mangroves. Overall, the results of this study highlight the importance of better conservation and management efforts for mangrove forests in Popalo Village to maintain the sustainability of coastal ecosystems.
