Abstract

The objective of this research was to assess the efficacy of three different decomposers in producing compost of high quality that meets the compost maturity standards (SNI 19-7030-2004). The experimental study was conducted with three treatments, each replicated five times, resulting in a total of fifteen composting holes. The research was conducted in South Batu Kuta Village, Narmada District, West Lombok Regency, from October to December 2019. The treatments included D1 (EM4 decomposer), D2 (Promi decomposer), and D3 (Phosphate Solubilizing Bacteria (PSB) decomposer). Various parameters, such as color, smell, temperature, pH, C-Organic, Total N, and C:N ratio, were assessed. The findings demonstrated that all three decomposers effectively decomposed the compost, yielding a high-quality product suitable for various plant applications. The compost produced by EM4, Promi, and PSB decomposers exhibited characteristics such as a blackish color, soil-like smell, a temperature ranging from 29.2°C to 29.8°C, a pH ranging from 6.83 to 6.87, organic carbon content ranging from 12.87% to 14.73%, total nitrogen content ranging from 0.83% to 0.87%, and a C/N ratio ranging from 14.35% to 14.60%. These results align with the compost maturity standards specified in SNI 19-7030-2004.

Abstract

Many microbial populations are found in the rhizosphere, including in the soil layer that follows the plant root system. Rhizosphere soils contain more bacteria, fungi and actinomycetes than non-rhizosphere soils. One of the antibiotic producing bacteria has been isolated from the rhizosphere. The purpose of this study was to isolate and characterize the biochemistry of antibiotic producing bacteria and to evaluate their superiority in inhibiting other types of bacteria. Three microbial isolates were isolated from the rhizosphere of winged bean (K) and banana (P1 and P2) plants. All isolated isolates were tested for antagonism with E. coli, Bacillus, and Pseudomonas bacteria on Nutrient Agar (NA) media to determine antibiotic-producing bacteria. Furthermore, identification and characterization of colony morphology and a series of antagonism and pathogenicity tests were carried out. The three isolates had irregular colony forms (isolates K and P1) as well as oval shapes (isolate P2), flat surface, glossy texture, milky white or cream color, and irregular edges. The antagonism test showed that isolates P1, P2, and K could inhibit the growth of bacterial colonies E. coli, Bacillus, and Pseudomonas, respectively. In the pathogenicity test, the three microbial isolates did not show symptoms of necrosis in tobacco leaves after 2 days of observation.
