Abstract

Coral reefs are the main ecosystem of coastal waters and tropical seas, and their preseance is very dominant in coastal waters and small islands of the Indonesia archipelago. Coral reefs have a very large role, therefore damage to the coral reef ecosystem can result in disruption of all marine and coastal life in the region.CPCe (Coral Point Count With Excel Extensions) is used to observe coral reefs. The data used are the results of photos taken using the UPT (Under Photo Transect) method from 2 observation stations in the waters of Popaya Island (Mas Popaya Raja Nature Reserve). The photos consisted of 51 photos for each station. Photos taken with the assumption that they can represent each station used. Each photo processed in CPCe used 30 random points. The results showed that the highest percentage of coral cover was found at station 1 at 59,8% while the lowest percentage of coral cover was found at station 2 with a value of 35,75%. This shows that the level of damage that occurs in the waters of Popaya Island is higher at station 2.

Abstract

This study aimed to describe Actinomycetes from the rhizosphere of plants in the Gorontalo karst area as Plant Growth Promoting Rhizobacteria (PGPR). The research method is based on a quantitative descriptive method. Soil samples from the rhizosphere were collected using a purposive sampling technique from 8 plant species at two locations in the Gorontalo karst region, namely the Tanjung Kramat Hills. The characteristics of PGPR in this study focused on phosphate solubilization ability, Indole Acetic Acid (IAA) production, antagonism against the fungus Fusarium oxysporum, and tolerance to fungicides. Potential PGPR isolates were analyzed for phylogenetic relationships based on 16S rRNA gene sequences. The results showed that there were 6 actinomycetes isolates (RzHKC-01, RzKO-02, RzO-03, RzAK-04, RzPK-05, and RzOC-06) from 8 plant species in the Gorontalo karst region. One actinomycetes isolate, RzPK-05, showed potential as a PGPR with the ability to solubilize phosphate and produce IAA at 0.165 mg/L and 0.133 mg/L, respectively. Isolate RzPK-05 exhibited antagonistic properties against Fusarium oxysporum with an inhibition rate of 82.24% and was tolerant to fungicides such as Captive, Benlate, and Thiramo up to a concentration of 100 mg/L. Molecular analysis based on the 16S rRNA gene and phylogenetic tree reconstruction indicated that the RzPK-05 isolate is closely related to the genus Streptomyces with 100% similarity.

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.
