Abstract

Sugar cane disease is a major factor in reducing sugar cane yields. The low intensity of experts to go into the field to check the condition of sugar cane causes the handling of sugarcane disease tends to be slow. This problem can be solved by instilling expert intelligence on sugar cane into an expert system. In this study the method of classification of sugar cane disease was proposed using Extreme Learning Machine (ELM). However, ELM alone is not enough to classify multilabel and multiclass disease case data in this study. Therefore, it is proposed to optimize the weight of hidden neurons in ELM using Particle Swarm Optimization (PSO). The experimental results show that the classification using ELM alone can reach an accuracy rate of 71%. After the weight of hidden neurons from ELM was optimized, the accuracy rate became 79.92% or an increase of 8.92%.

Abstract

Early Blight disease is an important disease of tomato plants caused by the fungus Alternaria solani. This disease attack can cause a decrease in production yields up to 78%. Control efforts using synthetic fungicides continuously can cause new problems for the environment. This research was conducted to determine the effect of fungicide applications with active ingredients Pyraclostrobin+Fluxapyroxad and the addition of biological agent Pseudomonas fluorescens on early blight disease and growth of tomato plants. This study consisted of in vivo and in vitro studies with observation parameters in the form of compatibility of bacteria with fungicides, fungicide inhibition, disease intensity, level of efficacy, and growth of tomato plants. The results showed that the combination of synthetic fungicide and Pseudomonas fluorescens was classified as compatible and effective in controlling Alternaria solani and able to support the growth of tomato plants. Combination treatment can reduce the use of synthetic fungicide by 25% of the recommended dose and is able to give results that are not significantly different from the recommended dose of synthetic fungicide treatment.

Abstract

Rice cultivation often face obstacles, and one of them is bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae (Xoo). The application of endophytic bacteria is one of solutions to overcome this problem. Endophytic bacteria are non-pathogenic bacteria, which live in plant tissues. These bacteria could be isolated from the plant tissues. They may adapt to the plant tissues and produce antibiosis that could increase the plant resistance. Therefore, objectives of the research were to isolate the endophytic bacteria from healthy plant tissues and to identify them through morphology, physiology, biochemistry, and molecular. Method of the research was explorative along with three principal activities, such as isolation, selection, and identification on the potential endophytic bacteria. The isolation of the endophytic bacteria from healthy rice tissues has resulted 53 isolates and five of them have antagonistic ability in vitro against Xoo. Isolate ak9 has the highest antagonistic ability, 7.67 mm, in comparison with other isolates. Results of identification showed that those five potential bacteria have close relations, such as da3 with Bacillus cereus, isolate ak9 with Burkholderia sp., isolate ak30 with Enterobacter sp and isolate da9, as well as ak15 are Corynebacterium sp.

Abstract

Shallot (Allium ascalonicum L.) is one of the vegetable commodities in the form of tubers that have a high economic value. The development of shallot cultivation in Indonesia often experiences obstacles, one of which is an obstacle in the process of shallot cultivation, namely the attack of Plant Disturbing Organisms (OPT). Information about diseases caused by pathogenic bacteria is still very limited. This study aims to determine the symptoms and identification of pathogenic bacteria that cause wilt in shallots. Bacterial isolation was carried out using Nutrient Agar (NA) media and 36 bacterial isolates were collected from shallots. Bacterial isolates were then tested for pathogenicity to determine the ability of bacteria to cause wilt disease in shallots. The results of isolation obtained 10 bacterial isolates that can show symptoms on red onions namely wilted leaves, yellow and soft rotten tubers. Four isolates including positive can show hypersensitivity symptoms, namely M11, N20, N17 and N14. Based on the identification of bacteria in physiology showed 2 groups of different isolates. Biochemical test results of Isolate M11, N20 and show species suspected of B. cepacia. N3 and N14 isolates are suspected to be E. carotavora subsp. carotavora. The bacterial isolates N7, N17, P5 and P7 were suspected to be E. carotavora subsp. betavasculorum. The isolate of N4 bacteria is suspected to be E. cacticida.

Abstract

Herbicides are a substance or chemical compound used to inhibit growth or kill plants. Herbicides are toxic to weeds or pests as well as cultivated plants. The impact of using the herbicide paraquat causes some microbes to become more resistant and has the potential to be used as a paraquat biodegradation agent. Indigenous yeast is one of the microbes that can be used as a biodegradation agent because it is resistant to the environment. For this reason, This research aimed to investigate the indigenous yeast isolated from the potato field in Sumberbrantas village, Batu City as a bioremediation agent for paraquat herbicide residues.The sampling was carried out in the potato field of Sumberbrantas, Batu City, which in routine maintenance uses a herbicide with active paraquat (1,1 dimethyl -4, 4-bipyridinium dichloride).The isolation results obtained 6 isolates of indigenous yeast which had the potential as biodegradation agents for paraquat. Treatment of yeast isolates MB 1, MB 3, MB 4, MB 6, MB 7, MB 8 at concentrations of 250, 500, 1,000 and 2,000 paraquat were able to survive with a growth percentage of 75-100%. At a concentration of 5,000 Isolated yeast decreased with a growth percentage of 50-75% and MB 1 isolate with 10,000 ppm concentration still survive with a growth percentage of 1-25%. The highest biodegradability ability of yeast was in MB 1. The identification of MB 1 isolates based on molecular characters have similarities in the basic structure of 98.89% with Geotrichum silvicola UFMG 354-228S isolates with accession number NG_0606221.1.

Abstract

Purple blotch caused by Alternaria porri is the primary disease in shallots, causing yield losses of 30-100%. The use of endophytic fungi as biocontrol agents has several advantages, including adaptability to host plants, selective targeting of pathogenic fungal cell walls without harming plant cells, and environmental friendliness. This study aims to select endophytic fungi producing hydrolytic enzymes with the highest inhibitory effect against A. porri. Endophytic fungi were isolated from the Batu Ijo local variety of shallots in Dau District, Malang, then evaluated for antagonism and for their ability to produce hydrolytic enzymes. This study obtained 42 isolates, consisting of 25 fungi and 17 yeasts. The endophytic fungi with the highest inhibitory activity were identified as Trichoderma asperellum (71.4%) and Pichia onychis (70.04%). T. asperellum produced cellulase at concentrations of 16.78 µg/ml and chitinase at 3.85 µg/ml, while P. onychis produced cellulase at concentrations of 11.47 µg/ml and chitinase at 1.56 µg/ml. Microscopic observation of A. porri hyphae showed that both endophytic fungi caused lysis with hyphal fragmentation, discoloration, and deformation. The endophytic fungi T. asperellum and P. onychis were proven to inhibit A. porri in vitro through their ability to produce hydrolytic enzymes that caused A. porri hyphal lysis.

Abstract

The apple farming group is one of the built of Department of Plant Pests and Diseases, Agricultural Faculty, Brawijaya University. In 2019, this departmen received a request from apple farmers in Madiredo Village, Pujon District to held an assistance programs of apple cultivation and environmentally pest control. This is related with the increasing of fruit rot and other diseases which is caused a decrease of apple production especially in Malang Regency. In general, apple farmers still rely on disease control using chemical fungicides which can have a negative impact on the environment and create resistance to pathogenic fungi. Therefore, this research was carried out to explore and study the potential of biological agents in apple production centers in Malang Regency, specifically in Poncokusumo, Pujon, and Batu District on conventional fields and mixed fields. This research was held observationally through fields surveys and farmer interviews, took soil samples and disease samples then then isolating, identifying and testing for antagonism at laboratory. Based on interviews and observation of symptomology, two dominant diseases were found, namely fruit rot disease (Gloeosporium sp.) and marsonina leaf spot disease (Marssonina coronaria). The results of exploration of the rhizospheric apple plants obtained isolates on conventional fields in Kec. Pujon has the highest abundance of fungal colonies compared to other regions. Based on the results of the antagonism test for pathogenic fungi and biological agents, it was found that the isolate codes KH.C, KK.A, JK.B, JK.J, and BK.B had the highest percentage of inhibition or the most effective in controlling the pathogen Gloeosporium sp. So in the next, the species can be identified molecularly.
