Abstract

Bacterial wilt disease is a serious threat to cayenne pepper plants because it can cause a significant reduction in production. Although Bacillus sp. has been applied using liquid formulations, the results have not been optimal. Therefore, bioencapsulated formulations in the form of Beads have been tested as an alternative to increase their effectiveness. These Beads were made using sodium alginate cross-linked with CaCl2 through an extrusion technique. The application of Beads with the K2W1 treatment combination showed the lowest disease intensity level, which was 55.5%, and the effectiveness of inhibition reached 44.5%. From the results of this study, it can be concluded that the beads formulation is significantly potentian in inhibiting bacterial wilt disease on chili plant

Abstract

Biological agent Bacillus sp. Based on the results of previous research, direct use of isolated microorganisms BCZ14, BCZ16, and BCZ20 was able to suppress Fusarium wilt disease. However, Bacillus sp. formulations in suspension form are less effective when applied in the field. This research focuses on analyzing the viability of three isolates of Bacillus sp. against several combinations of bioencapsulation coating materials. The experimental design used was a completely randomized design with a combination of treatment of three isolates and three types of coating materials, namely sodium alginate (B1), carrageenan (B2), and chitosan (B3) each 2%. Each treatment combination was repeated five times. Based on the experiments that have been carried out, the bioencapsulation formulation using 2% chitosan coating material was able to maintain the viability of the three isolates of Bacillus sp. BCZ14, BCZ16, and BCZ20. The population density of the three isolates of Bacillus sp. persisted consistently from the first week to the last week of observation. Therefore, the 2% chitosan coating material can be said to be able to maintain the viability of Bacillus sp. within six weeks.

Abstract

Cayenne pepper (Capsicum frutescens L.) is a horticultural crop in Indonesia that often has many obstacles. The main obstacle that is often faced is wilt disease caused by the fungus Fusarium oxysporum. Bacillus spp. bacteria have the potential to control the fungus F. oxysporum. The purpose of this study was to determine the ability of Bacillus spp. bacteria in controlling fusarium wilt disease. This research was conducted from August to November 2023 at the Plant Health Laboratory and screen house of the Faculty of Agriculture, National Development University "Veteran" East Java. The study used a Factorial Complete Randomized Block Design with three replications and nine treatments so that there were 27 experimental units. The observation variables included incubation period, disease intensity, plant height, number of leaves, first flower appearance and fruit wet weight. The research data were analyzed using ANOVA analysis of variance procedure to determine whether there is an effect of each treatment. If it is known that there is a significantly different effect from the treatment, it will be continued with the DMRT test at the 5% level. The results showed that the combination of Bacillus spp bacteria and dosage had an effect on the incubation period and disease intensity. The results showed that the combination of Bacillus spp bacteria and doses had an effect on vegetative phase parameters, namely plant height and number of leaves. However, the combination of Bacillus spp and dosage showed that the generative phase parameters did not significantly affect the first flower appearance and fruit wet weight

Abstract

The use of biological agents such as Bacillus sp. bacteria has begun to be widely used by farmers as a new form of control. Bacillus sp. needs to require special methods in its application because it has certain living conditions, and Bacillus sp. is vulnerable to environmental pressures. Bioencapsulated formulation in the form of granules is considered effective as a form of bacterial application in soil because it is able to protect Bacillus sp. and maintain survival. This study aims to determine the best concentration of sodium alginate in maintaining the viability of Bacillus sp. at the in vitro stage and to see changes in the size of the beads. The beads were made using extrusion method by combining Bacillus sp. suspension and sodium alginate suspension at 1%, 1.5%, and 2% concentration. The concentration of sodium alginate was not a major factor in changes in bead size and viability test results experienced significant changes in each observation. 1.5% and 2% concentrations can reach the highest viability value of 3x106 CFU/mL and decreased during 1 month of observation. Changes in bead size and viability were caused by the alginase enzyme produced by Bacillus sp.

Abstract

Corruption obliteration presently focuses on three main issues: prevention, obliteration, and asset recovery. Eradicate corruption not only focuses on preventing and eradicating but also improves the terms of punishing the perpetrators and is also associated with seeking to recover state financial losses from the proceeds of corruption crimes. The provisions in question are of great hope for systematic and comprehensive anti-corruption measures, which feature not only criminal prosecution of corruption crimes but also the protection of national finance, that is, the obligation to return state funds from the perpetrators of criminals. Corruption crimes can be used for national development. Therefore, normatively it would not be excessive if the provisions of Article 18 of Constitution no. 31 of 1999 in conjunction with Constitution no. 20 of 2001 regarding the Obliteration of deceits of corruption can be an effective legal instrument for compensating the State for losses caused by corruption crimes.

Abstract

The use of biological agents such as Bacillus sp. Bacteria have started to be widely used by farmers as a new form of control. Bacillus sp. needs to require a special method in its application because it has certain living conditions, and Bacillus sp. is susceptible to environmental stress like other microorganisms. Apply Bacillus sp. as a biological control agent in the field, it needs to be formed into a formulation to be more effective and efficient when applied. Liquid formulations often used cannot maintain the viability of bacteria in the soil. The bioencapsulation formulation in the form of microcapsules is considered more effective in maintaining the viability of bacteria in the soil. This study aims to determine the effect of concentration on the encapsulation efficiency of Bacillus sp. inside the microcapsule. Beads are made using the extrusion method by combining a sodium alginate suspension of 1%, 1.5%, and 2% concentration and a bacterial suspension and dropping it into a calcium chloride solution. The encapsulation efficiency test was carried out once by extracting the bacteria on the beads, growing them in the growth medium, and then observing them. The results of the encapsulation efficiency test with a concentration of 1%, 1.5%, and 2% had values of 1%, 0.36%, and 1.35%, respectively. The difference in the results of this encapsulation efficiency indicates that there is an effect of sodium alginate concentration on the value of encapsulation efficiency.

Abstract

Wheat is one of the most popular commodities and is often consumed by the Indonesian people. In 2019, wheat was consumed at least 30.5 kg/year by the Indonesian people. The import of wheat in large quantities allows the risk of carrying OPTK, especially fungi with OPTK category A1, so detection and identification of wheat seeds entering Indonesia is needed. This study aims to detect and determine the fungi found in wheat seeds from Canada (Canada I and Canada II) using the Washing Test method at the Surabaya Agricultural Quarantine Center. The Washing test method is a washing method to release fungi on the surface of seeds using sterile distilled water and a centrifuge. The stages of this method are as follows sampling of wheat seeds from Canada, detection using the washing test method, and microscopic identification. The results of detection and identification on wheat seeds did not find the target pest but other fungi were found in Canada I sample, namely Cladosporium variabile, Cladosporium sp., Puccinia sp., Puccinia graminis and in Canada II sample Cladosporium variabile, and Puccinia graminis. Further quarantine measures for imported wheat grains are exemptions with the issuance of a plant exemption certificate (KT-9). Service procedures at the BBKP Surabaya laboratory are carried out in accordance with Law No. 21 of 2019, MOA No. 25 of 2020 and ISO 17025 with 2P quarantine measures (Inspection and Exemption).
