Abstract

Endophytic bacteria have been reported to produce metabolite as antifungal compound. This study was aimed to obtain endophytic bacteria which are able to produce metabolite to control Fusarium sp., a potential seedborne fungi on maize. Endophytic bacteria were screened by hypersensitive test on tobacco leaves and antagonistic test. Endophytic bacteria isolates with high growth inhibitor activity were selected and examined for their metabolite compound. Thre isolates, i.e. Lactobacillus sp. isolate EF14III, Pseudomonas sp. isolate ER1I, dan Aeromonas sp. isolate ER10I has the potential to inhibit Fusarium sp..  Metabolite compound of Pseudomonas sp. isolates ER1I was able to decrease the infection Fusarium sp. by 65.0% in blotter test and decreased infection of Fusarium sp. up to 59.5% and 60.5% in growing on test using water agar and sterile soil, respectively.  Cyclohexanone with concentration of 9.68% produced by Pseudomonas sp. isolat ERI1 may play a role as antifungal compound.

Abstract

The yard in Medan Denai Subdistrict is actually still quite extensive, but most of it is not used for vegetable crops so it is not possible to plant other crops such as vegetables. The main problems that occur in the target community are 1) there are not many activities of the Aisyiyah mothers group related to community empowerment, 2) the yard environment in Medan Denai District is largely untapped for vegetable crops, 3) most members of Aisyiyah do not have knowledge , insight and skills in intensifying the land area to be more productive and provide added value to the community, and 4) the potential of human and natural resources in Medan Denai Subdistrict has not been utilized optimally. To achieve the stated objectives, several methods are used, namely: 1) counseling, which is conducted by gathering organizational leaders and pilgrims to participate in counseling on women's empowerment, managing land and verticulture cultivation technology, with resource persons from the Implementation Team, 2) technology transfer by procuring verticultural installations with various models, as well as preparing other facilities that support this activity, 3) demonstration and training carried out by simulating verticulture cultivation practices using equipment and materials prepared by program implementers, 4) verticulture cultivation practices to produce products , and 5) periodic accompaniment to foster and assist partners until they successfully carry out verticultural cultivation until they achieve optimal results. The results of the Kemuhammadiyaan Coaching program show that the Coaching program provides great benefits for program participants because it can increase the insight, knowledge and skills in using the land so that it becomes more productive.

Abstract

Soybean plants (Glycine max) are the third most important food commodity crop after rice and corn. Soybean production continues to be improved in meeting community needs, but efforts to increase soybean production still face problems, namely green ladybird pest (N. viridula L.). One alternative to control soybean pod sucking insects that are relatively safe, inexpensive, and easily obtained is the use of vegetable insecticides. Vegetable insecticides do not quickly cause pest resistance, are synergistic, and their use can be combined with other pest control techniques. One of them is by using Tagetes erecta plants combined with cow urine as a vegetable insecticide. The use of repellents generally does not directly kill insects, but rather serves to reject the presence of insects, mainly due to the pungent smell. The use of cow urine as a mixture of biopesticides contains growth stimulants and contains repellents for several types of insect pests. This study aims to determine the effectiveness of Tagetes erecta in reducing the population of N.viridula pests in soybean plants (Glycine max L.Merr). Non Factorial RAK with 5 levels of treatment and 5 replications. Hopefully with this study farmers can take advantage of tagetes erecta and cow urine waste that can be used as natural pesticides and can be used as a control for Hama Nezara viridula which is environmentally friendly and economic.

Abstract

Salah satu faktor utama penyebab penurunan produksi jagung adanya serangan OPT (Organisme Penganggu Tanaman) baik itu hama maupun penyakit yang disebabkan oleh mikrooragnisme terutama cendawan patogen. Cendawan patogen dapat menginfeksi langsung tanaman jagung ataupun menginfeksi benih jagung. Cendawan patogen yang terbawa pada benih dapat mengubah bentuk dan warna benih, hilangnya daya kecambah dan vigor benih, selain itu cendawan patogen yang terbawa pada benih yang tumbuh berpotensi menyebabkan penyakit pada saat perkecambahan atau tanaman dewasa, sehingga tanaman menjadi sakit dan mengurangi hasil produksi. Penelitian ini menggunakan metode standar ISTA (International Seed Testing Association). Isolasi cendawan patogen terbawa benih dilakukan dengan metode blotter test yaitu menginkubasi benih di atas kertas saring lembab, selanjutnya cendawan patogen yang muncul didentifikasi. Cendawan patogen yang diperoleh diuji patogenisitasnya terhadap benih jagung. Hasil deteksi dan identifikasi cendawan pathogen terbawa benih jagung lokal diperoleh cendawan Fusarium sp. yang paling tinggi persentasenya menginfeksi benih jagung varietas lokal asal Sumatera Utara yaitu sebesar 78,75% untuk benih jagung varietas lokal asal Deli serdang, 14,5% untuk benih jagung varietas lokal asal Langkat dan 59,5% untuk benih jagung varietas lokal asal Karo.

Abstract

Soil-borne soil pathogens are pathogens that inhabit the soil and can survive for years in the soil, making them very difficult to control. Control with pesticides and fungicides harms the ecosystem, so other controls are needed such as soil solarization. This study aims to determine the growth response of soil-borne pathogens and soil microbial populations to soil solarization treatment. The study used a completely randomized design with 4 treatments consisting of solarization on soil media, solarization on soil and compost media, without solarization on soil media, and without solarization on soil media and compost on plastic trays. Each treatment was repeated 4 times. The soil-borne pathogens used were Sclerotium rolfsii and Rigidoporus lignisus. Each pathogen was planted in each planting medium with a depth of 5 and 10 cm. Then each tray is covered with 0.1 mm thick transparent plastic. Then given solarization treatment for four weeks. At the end of the observation, sclerotia and R. lignosus were grown on PDA media to be tested for pathogen survival and the solarization efficacy against pathogen growth was calculated. Soil samples from each treatment were also taken to calculate the soil microbial population. The results showed that soil solarization was able to suppress the growth of R. lignosus by 80-100% and S. rolfsii by 100%. Meanwhile, the microbes found in the soil solarization treatment consisted of groups of bacteria and fungi, respectively 7.67×104–1.90×107 CFU.mL-1 and 1.00×104–5.82×105 CFU.mL-1.
