Abstract

Bird’s eye chili is a type of plant with a very high market price. The low production of bird’s eye chili is influenced by factors such as water supply and seedling density, both of which affect plant growth and yield. This study aims to investigate the effects of water volume and seedling density per planting hole and their interaction on the growth and yield of bird’s eye chili. The study was conducted at the agricultural instrument standardization agency (BSIP) in Gorontalo Province from May to September 2024. The study used a factorial randomized bloch design (RBD). The first factor was water volume with three levels, and the second factor was seedling density with two levels. The parameters observed included plant height, leaf area, flowering age, number of fruits, and fruit wight. The data were analyzed using ANOVA followed by duncan’s multiple range test (DMRT) at a 5% significance level. Water volume significantly affected plant height, flowering age, and the weight of the first harvest fruit. In addition, No. interaction was found between water volume and seedling density for any of the observed parameters.

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.
