Abstract

Peningkatan permintaan cabai di Indonesia diiringi dengan tantangan produksi, salah satunya adalah penyakit antraknosa yang disebabkan oleh Colletotrichum sp. Penyakit ini menurunkan hasil dan kualitas buah, dan umumnya dikendalikan dengan fungisida kimia. Penggunaan fungisida kimia menimbulkan risiko terhadap kesehatan dan lingkungan, sehingga diperlukan alternatif pengendalian hayati. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak bawang putih sebagai agen hayati terhadap Colletotrichum sp. secara in vitro dan membandingkannya dengan fungisida propineb. Penelitian menggunakan rancangan acak lengkap faktorial (RALF) dengan dua faktor, yaitu jenis perlakuan (ekstrak bawang putih dan fungisida kimia) dan konsentrasi (5%, 10%, dan 15%). Parameter yang diamati meliputi diameter koloni, persentase hambatan, intensitas serangan pada buah, serta karakteristik makro dan mikroskopis jamur. Hasil menunjukkan bahwa ekstrak bawang putih 15% mampu menghambat pertumbuhan jamur sebesar 38.73% dan intensitas serangan sebesar 21.33%, sedangkan fungisida propineb 5% menunjukkan hambatan tertinggi sebesar 78.43% dan intensitas serangan terendah sebesar 2.67%. Hasil ini menunjukkan bahwa ekstrak bawang putih memiliki potensi antijamur. namun efektivitasnya masih lebih rendah dibandingkan propineb.

Abstract

Rice (Oryza sativa L.) is one of the important food commodities consumed by the Indonesian people. One of the reasons for the decline in rice production is infection by the pathogen Xanthomonas oryzae pv. oryzae (Xoo) which causes bacterial leaf blight (BLB) and it’s seed-borne pathogen. The purpose of the experiment is to to evaluate the effectiveness of seed soaking using Paenibacillus sp. to control BLB in rice plants. Efforts to control BLB and improve rice plant growth were carried out by seed treatment using biocontrol agent has potential as biological control for BLB in rice plants by producing antibiotic. This experiment used a Completely Randomized Design with 4 treatments (control, Paenibacillus sp., Bacillus sp. BTH22, Paenibacillus polymyxa) and 5 replications. Data analysis was performed using analysis of variance (ANOVA) at a 5% significance level using IBM SPSS Statistics version 22 software. If the analysis results showed significant differences between treatments, an Honestly Significant Difference (HSD) test was performed at the 5% level. The research results showed that seed soaking using Paenibacillus sp. was able to reduce the incubation period of HDB disease by up to 11 days, with the lowest disease attack intensity being 10.21%, the highest seed germination rate being 91.25%, and an efficacy level of 53.32%.

Abstract

Rice is a major food commodity in Indonesia that is currently experiencing a decline in production due to several factors, one of which is bacterial leaf blight (BLB) caused by the bacterium Xanthomonas sp. The use of chemicals in controlling this disease has many limitations, so alternatives are needed, such as antagonistic microbes. This study aims to evaluate the effectiveness of Bacillus sp. BTH22 and Trichoderma sp. individually and in consortium in suppressing BLB disease in rice plants in vitro and in vivo. The study was conducted at the Plant Health Laboratory of  Universitas Pembangunan Nasional “Veteran” Jawa Timur and Green House of Kebun Bibit Wonorejo from March to June 2025. The methods used included in vitro diffusion well test and in vivo disease intensity observation with a completely randomized design consisting of 5 treatments, namely control and spraying of antagonistic microbes Bacillus sp. BTH22 and Trichoderma sp. alone or in consortium with 4 replicates. Data analysis used analysis of variance (ANOVA) and post-hoc HSD tests at a 5% significance level. The results show that the treatment with the Bacillus sp. BTH22 and Trichoderma sp. consortium was the most effective, with an inhibition zone of 13 mm, which is classified as strong, and the lowest disease intensity of 30.02% at 55 HST with a suppression rate of 69.98%. These results indicate that the consortium of the two antagonistic microorganisms has high potential as an effective and sustainable biological control agent for BLB based on the observed parameters of inhibition zone and disease attack intensity.

Abstract

This study investigated the effects of Streptomyces sp. encapsulated in sodium alginate beads on the growth and health of shallot (Allium cepa L.) plants. Different sodium alginate concentrations (2%, 2.5%, and 3%) and application timings (7 days before transplanting and at transplanting) were tested. The mass and diameter of the beads showed slight decreases over storage time, indicating some shrinkage but maintaining structural integrity to protect the bacteria. Encapsulation efficiency was highest at 3% sodium alginate, which also correlated    with    increased    bead     stability.     Viability     tests     revealed that Streptomyces maintained high colony-forming units (CFU) across the treatments, confirming the protective effect of the encapsulation. Application of beads significantly reduced Fusarium wilt disease intensity and improved bulb weight. Treatments with higher sodium alginate concentrations and earlier application times showed the most pronounced benefits. These findings demonstrate that beads using optimal sodium alginate concentration and timing enhance microbial viability and biological control efficacy, contributing to healthier and more productive shallot cultivation.

Abstract

The use of a fungicide containing the active ingredient mancozeb in shallot fields to control moler disease, if not managed in terms of dose and frequency, it has the potential to harm soil in physical, chemical and biological ways. One method for repairing this damage is too use local microbes. This research attempts to determine the types of bacteria in soil treated to mancozeb fungicide through a morphological and physiological characterization process. Soil samples were collected from the shallot producing region of Balongrejo District, Nganjuk Regency. The method in this research is to isolate soil samples at a depth of 0-20 cm. Bacteria were isolated and multiplied using the streak plate technique on nutrient agar medium. Identification was performed on macroscopic and microscopic morphological features well as physiological characters based on the method of Schaad et al. (2001). Bergey's Manual of Determinative Bacteriology Ninth Edition was then used to identify the isolated bacteria. The research results showed that 14 bacterial isolates were isolated, 5 isolates suspected to be the genus Bacillus, 7 isolates suspected to be the genus Corynebacterium, 1 isolate suspected to be Lactobacillus, and 1 isolate unidentified. All indigenous bacterial isolates were able to reduce the concentration of mancozeb fungicide through measurements using a UV-Vis spechtrophotometer with a wavelength of 268 nm. The highest degradation percentage was bacterial isolate I8 (75%) and the lowest was bacterial isolate I7 (19%).

Abstract

The main objective was to determine the effectiveness of this technique in establishing endophytic colonies and its impact on plant vegetative growth. The experiment was conducted in the laboratory and greenhouse using a Completely Randomized Design (CRD) approach. We tested four levels of conidial density: control (no conidia), 1×10⁶, 1×10⁷, and 1×10⁸ conidia per mL, with each replicated five times. Parameters we observed included root and stem colonization success, plant height, and leaf number. Data were analyzed using ANOVA followed by a HSD test at the 5% level. The results showed that B. bassiana is able to enter and develop internally within root and stem tissues. Interestingly, the highest colonization occurred at the lowest concentration (1×10⁶ conidia per mL), with 83.3% in roots and 66.7% in stems. Although statistically, differences in concentration did not always have a significant effect on plant height and leaf number, numerically, inoculated plants showed better growth than controls, especially at 28 days after planting. From these findings, we conclude that soil application of B. bassiana is quite effective in establishing endophytic colonies without disrupting vegetative growth. In other words, this method is worth considering as part of a more environmentally friendly and sustainable pest management strategy.

Abstract

The fall armyworm (Spodoptera frugiperda) poses a problem for corn plants (Zea mays L.). The use of endophytic bacteria Bacillus sp. as an entomopathogen is expected to control the S. frugiperda pest. This study aims to determine the effective concentration of the bacteria and the active compounds produced by Bacillus sp. strain Bth 22 in controlling S. frugiperda. The research was conducted from August to October 2024 at the Plant Health Laboratory of the Faculty of Agriculture, UPN "Veteran" East Java, and the Airlangga Research Hub in Surabaya. The study was designed using a completely randomized design (CRD) with bacterial concentration treatments of 0% (control), 10%, 15%, 20%, 25%, 30%, and 35%, repeated five times. Observational parameters included mortality rate, number of pupae and imago formed, as well as the mechanisms and compounds produced by Bacillus bacteria based on HPLC and FT-IR tests. The application of Bacillus sp. Bth-22 affected the mortality parameters, the number of pupae formed, and the number of imago formed. The Bacillus sp. Bth-22 bacteria produced metabolites in the form of hydrocarbon derivatives and amide group compounds, disrupting metabolism and digestion, leading to the mortality of S. frugiperda. Keywords: Entomopathogen, Metabolite compounds, Spodoptera frugiperda, Zea mays

Abstract

Low-quality seeds can negatively affect the success of agricultural practices by reducing yield and increasing susceptibility to pathogen infection. Pathogens may infect seeds starting from the field, during transportation, and throughout storage. The utilization of Bacillus sp. as a biological control agent has been extensively studied due to its ability to produce secondary metabolites with antifungal properties. This study aimed to determine the effective concentration level of secondary metabolites of Bacillus sp. Bth-22 in suppressing Colletotrichum sp. infection on chili pepper (Capsicum frutescens L.) seeds using the blotter test method. The experiment was arranged in a completely randomized design (CRD) with a single factor consisting of concentration levels (10%, 15%, 20%, 25%, and 30%), sterile distilled water, and the chemical fungicide propineb as controls. The results showed that treatment with various concentrations of secondary metabolites of Bacillus sp. Bth-22 significantly affected the infection level, with concentrations of 30% (G) at 36%; 25% (F) and KP (B) at 38.6%; 20% (E) at 40%; 15% (D) at 42.6%; and 10% (C) at 44%, compared with the negative control. In addition, treatments also suppressed infection levels, with 30% (G) at 43.3%; 25% (F) and KP (B) at 39.3%; 20% (E) at 37%; 15% (D) at 33.6%; and 10% (C) at 31%. Furthermore, application of Bacillus sp. Bth-22 secondary metabolites induced abnormalities in fungal hyphae, such as curling, twisting, and bending, indicating antifungal activity of the bioactive compounds produced by Bacillus sp. Bth-22.

Abstract

Shallot (Allium ascalonicum L.) is a key horticultural crop in Indonesia, but its productivity is constrained by moler disease caused by Fusarium sp. Chemical fungicides have limited effectiveness and raise environmental concerns, necessitating eco-friendly alternatives such as Bacillus spp. This study aimed to evaluate the potential of Bacillus spp. in suppressing moler disease and promoting shallot growth and resistance. A factorial Completely Randomized Design (CRD) was employed under in vitro and in vivo conditions, with two factors: Fusarium sp. inoculation (with and without) and Bacillus spp. treatments (control, Bcz 14, and Bcz 20). Results demonstrated that Bacillus spp., particularly isolate Bcz 20, significantly reduced disease intensity by up to 73.91% and delayed symptom development. Moreover, Bacillus spp. enhanced plant growth and induced the accumulation of flavonoids and saponins. These findings indicate that Bacillus spp. function as effective biological control agents and plant growth promoting rhizobacteria (PGPR), offering a sustainable strategy to improve shallot productivity while reducing reliance on chemical fungicides.
