Abstract

The objective of this study is to ascertain the pathogenic and antagonistic fungi that induce disease in avocado plants (Persea americana Mill), identify the antagonistic fungi with the greatest antagonism potential among a variety of antagonistic fungi, and elucidate the mechanism by which antagonistic fungi inhibit the growth of pathogenic fungi. From January to May 2023, this study was conducted in vitro at the Microbiology Laboratory, State University of Malang, employing a completely randomized design (CRD) comprising six replications and four interventions. The identification of mold was accomplished through macroscopically and microscopically descriptive analysis, followed by a comparison with the mold identification key book. The antagonism process was executed utilizing the dual culture method on the PDA medium, and the electron microscope (SEM) was employed to witness the antagonism mechanism. The research findings revealed that T. harzianum spp. and T. viride were identified as antagonist fungi, whereas C. aotearoa and C. gloeospoiroides were identified as pathogenic fungi. The antagonistic fungus T. viride exhibited the greatest degree of antagonism, impeding the growth of C. gloeospoiroides by 77.8%. Observed antagonism occurs when the hyphae of the antagonistic mold ensnare, entangle, and pierce those of the pathogenic mold, causing harm to the region surrounding the pathogenic mold's hyphae and subsequently impeding its growth

Abstract

Indonesia has two of the three amphibian orders, Gymnophiona and Anura. Frogs in Indonesia have ten families. In West Java, there are 28 Anura species from six families. In general, frog habitats are very diverse and can be found in urban areas. However, the distribution in the IPB Dramaga campus, especially in the lake ecosystem is still unknown. Therefore, this research aims to determine the diversity and distribution of the Anura order in the Lake Ecosystem of IPB Dramaga. The method used is the Visual Encounter Survey (VES). The research locations are the three lakes ecosystem at IPB Dramaga (SDGs, Inspirasi Lake, LSI). This research recorded eight species, including Duttaphrynus melanostictus, Ingerophrynus biporcatus, Fejervarya cancrivora, Limnonectes macrodon, Hylarana erythraea, Amnirana nicobariensis, Microhyla achatina, and Polypedates leucomystax. Species D. melanostictus and F. cancrivora are distributed throughout the lake. This study recorded that the Shannon-Wiener diversity in the IPB Dramaga Lake ecosystem (SDGs, Telaga Inspirasi, LSI) was in the medium category (1.28–1.71). Brillouin Diversity Index is in the high category (1.18– 1.50). The evenness index (0.82–0.92) was close to even. Simpson's Dominance Index (0.21–0.30) and Margalef's Species Richness (1.17–1.91) were low.
