Abstract

ABSTRACT: The research aims to determine the effect of PGPR application on the incidence of fusarium wilt disease and tomato plant production. The research was carried out using a Randomized Group Design (RAK) with one treatment factor, namely the PGPR dose. Treatment was made in five levels, namely D0 (control/no PGPR), D1 (5 cc PGPR/liter air), D2 (10 cc PGPR/liter air), D3 (15 cc/liter air) and D4 (20 cc PGPR/liter air air). The results of in vitro PGPR testing provided an inhibitory response to Fusarium growth with an average of 47.32% on PDA media and 63.12% on NA media. The PGPR dose treatment tested did not have a significant effect on plant height, number of leaves, production characteristics and disease intensity, except for the average number of branches per tree, root length and root weight. Giving a dose of 20 cc/liter is the best dose to increase root character and number of branches.

Abstract

ABSTRACT: The mangrove endophytic bacterial isolate Scyphiphora hydrophyllacea has antimicrobial capabilities and also has other bioactive compounds to be developed in the field of biotechnology. The aim of this study was to identify the endophytic bacterial isolate SH 14 obtained from the S. hydrophyllacea mangrove based on 16S rDNA sequence analysis. Molecular-based identification of bacteria, namely DNA amplified by Polymerase Chain Reaction (PCR) using primers 27F and 1492R and has a gene amplification of 1481 bp. Sequence data analyzed using the BLAST program showed that isolate SH 14 had a homology level of 99.43% with Brevibacillus brevis. This similarity value is a reference in determining bacterial identification, where bacteria are categorized as the same species if they have a similarity of 99%.

Abstract

ABSTRACT:The coastal ecosystem of Samai Island is a complex interaction between various organisms, including gastropods, and their environment. Gastropods are members of the mollusk phylum, which are invertebrates. This study aims to analyze the correlation between the structure of the gastropod community and physicochemical parameters. The research was conducted on the coast of Samai Island, Fakfak Regency, West Papua Province. Using the transect line method at four sampling stations. The results, showed that the highest gastropod density was found at Station IV (80.2 ind/m2), while the lowest was recorded at Station I (21.8 ind/m2). The gastropod diversity index ranged from 2.36 to 3.14, indicating a medium category at Stations II, III, and IV, and a high category at Station I. The evenness index was high at all stations, with values ranging from 0.61 to 0.87, and there was no dominant species at any station. The physico-chemical parameters of the water at the research location include water temperature ranging from 29.5°C to 30.4°C, salinity between 33.19‰ and 33.94‰, dissolved oxygen (DO) between 5.35 mg/L and 5.74 mg/L, and water pH ranging from 8.41 to 8.65. These parameters influence the structure of the gastropod community along the coast of Samai Island, Fakfak.

Abstract

Zooplankton play an important dual role in marine ecosystems as food webs connectors and sensitive indicators of water quality. This study examines the composition, abundance, and relationship of zooplankton communities with oceanographic parameters in the coral reef ecosystem of Manokwari Waters. Samples were collected from three observation stations: Kaki Island, Lemon Island, and Marampa Port, using a 25 μm plankton net. Morphological identification resulted in six classes of zooplankton, namely Hexanauplia, Gastropoda, Bivalve, Malacostraca, Branchiopoda, and Ostracoda, for a total of 23 species. The class Hexanauplia dominates in all locations, with the most abundant species being Undinula vulgaris (10 individuals), Calanus sinicus (7), and Eurytemora pacifica (6). Cluster analysis based on the Bray-Curtis similarity index with the Average Linkage method shows the similarity of zooplankton communities between Marampa Port and Lemon Island. Kaki Island forms a separate cluster, indicating differences in species composition spatially. The highest abundance was recorded in the Hexanauplia class with an abundance index of >2,500 cells/L in some species. Canonical Correspondence Analysis (CCA) revealed a positive correlation between DO and Bivalvia (+0.99), temperature with Gastropoda (+0.92), and salinity with Hexanauplia (+0.28). Environmental factors such as temperature, DO, pH, and depth have been shown to influence the spatial distribution and diversity of communities. These findings reinforce the dual role of zooplankton as a fundamental food source for benthic organisms such as the soft coral Sarcophyton sp. and as an effective bioindicator for monitoring the health of tropical coastal ecosystems.

Abstract

ABSTRACT: Blood disease is a significant problem in Kepok banana cultivation, resulting in substantial economic losses. Blood disease is caused by the pathogenic bacteria Rastolnia syzygii subsp. celebecensis, a soil-borne disease. Soil microbes play a crucial role in the biocontrol process because they can produce certain enzymes or metabolites that can suppress disease-causing pathogens in plants. One approach is the use of fungi as antagonistic biological agents that can protect plants from disease attack. The presence of fungal biological agents in the rhizosphere of Kepok banana plants infected with blood disease requires isolation and identification of soil fungi to obtain data on the diversity of indigenous rhizosphere fungi in Kepok banana plants infected with blood disease in Bremi, North Manokwari District. The results of the isolation and identification of rhizosphere fungi in Kepok banana plants infected with blood disease yielded six (6) fungal isolates with high disease virulence and eleven (11) fungal isolates with moderate disease virulence. The fungal isolates obtained from the rhizosphere of high disease virulence were identified as Trichoderma sp1., Rhizoctonia sp., Aspergillus sp1., Aspergillus sp2., Trichoderma sp2., and Trichoderma sp3. Fungal isolates obtained from the rhizosphere of moderate disease virulence were identified as Fusarium sp1., Fusarium sp2., Penicillium sp1., Aspergillus sp1., Aspergillus sp2., Trichoderma sp1., Trichoderma sp2., Trichoderma sp3., Fusarium sp3., Penicillium sp2., and Penicillium sp3.
