Abstract

Lake Perintis is a strategic lake as a tourist spot that has unspoiled environmental conditions that have the potential to find various types of macroscopic fungi, especially Basidiomycota fungi. Macroscopic fungi are a group of cellulose degrading fungi which have a very important role for the environment. This study used a quantitative descriptive method with field sampling using an exploratory survey method. This method aims to make direct observations in all research locations in order to obtain more in-depth data. This study aims to determine the diversity of types of Basidiomycota fungi found in Lake Perintis. By using the field note form to identify the fungi in the Perintis lake location. The results showed that Lake Perintis has a type of Basidiomycota fungi consisting of 2 class, 5 ordo, 10 family, 18 genus and 21 species.

Abstract

The study aims at identifying the properties and number of macroscopic fungi species from the Ascomycetes and Basidiomycetes divisions within the Mas Popaya Raja Natural Reserve Island of Dunu Village, Monano Sub-district of Gorontalo Utara. Information on the results of this research can be used as fungi inventory data for the Agency for the Conservation of Natural Resources Conservation Section II of Gorontalo. This research employs an explorative survey method to directly observe the existence of macroscopic fungi within the natural reserve. The study is implemented in sequence, initial observation within the natural reserve to determine the sampling points, followed by identification of those macroscopic fungi based on the morphology of those fungi. Qualitative descriptive method is used to analyze the data by describing the properties of those macroscopic fungi in their habitats. This study has shed light on ten types of macroscopic fungi available in this natural reserve namely: Aleuria aurantia, Xylaria papyrifera, Microporus xanthopus, Lentinus sajor-caju, Ganoderma lucidium, Ganoderma applanatum, Rigidoporus sp, Maramius androcaseus, Lichenomphalia umbellifera, Scleroderma sinnamariense. The fungi found were dominated by the Basidiomycota division of the Agariomycetes class.

Abstract

The community of Ulapato B Village possesses significant potential in developing eco-friendly products based on organic waste management, supported by the availability of raw materials. However, this potential has not been optimally utilized due to limited knowledge and technical skills. The Community Partnership Program (PKM) aims to enhance community capacity through the application of Biohack Eco-Enzyme innovation as an environmentally friendly product that can be utilized in the fields of health, agriculture, and the creative industry. The activities carried out include education, training in eco-enzyme production, hands-on mentoring, and product application. Evaluation results indicate a significant improvement across various assessed indicators, including community knowledge in waste management (85%), understanding and practical skills in eco-enzyme production (75%), utilization of eco-enzyme in health (75%), agriculture (80%), and creative industry (70%). These achievements demonstrate that the Biohack Eco-Enzyme innovation is effective in enhancing awareness, skills, and the utilization of organic waste into value-added products. This program not only contributes positively to waste reduction and environmental quality improvement but also opens opportunities for the sustainable development of a creative economy based on local resources

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.
