Abstract

Streptomyces sp. and Trichoderma sp. are biological agents that have high potential to produce secondary metabolites to reduce losses of agricultural products caused by pests. This study aims to determine the multientomopathogenic potential of Streptomyces sp. and Trichoderma sp on EKG and GN media on feeding behavior of Spodoptera litura pests in vitro. 10 S. litura (2nd instar) were placed in a box then the larvae with each entomopathogenic treatment. Besides, feed as much as 5 grams for each box every day for 7 days. Observations were made by weighing the difference in daily feed weight for 7 days. Effect of treatment on feeding activity of Spodoptera sp. on the 7th day after application showed that EKGST 5: 1 treatment had the highest value due to the activity of the chitinase enzyme from Streptomyces sp. and Trichoderma sp. Calculation of the ability of chitin hydrolysis by the enzyme chitinase is done by calculating the diameter of the clear zone that is formed then reduced by the diameter of the blotting paper containing supernatant secondary metabolites. Chitinase testing was carried out to determine the ability of secondary metabolites produced by Streptomyces sp. and Trichoderma sp. in hydrolyzing chitin. The widest zone is produced by multientomopathogenic Streptomyces sp. and Trichoderma sp. in EKGST 5: 1 treatment 3cm. Damage to the digestive tract due to the chitinase enzyme causes a decrease in the ability to absorb nutrients that have an impact on the reduced activity of Spodoptera litura.

Abstract

Chili (Capsicum sp.) is a vegetable commodity that is widely grown throughout the world after tomatoes are a member of the Solanaceae family, which have very many types, ranging from not spicy to very spicy. Chili originates from South America and Central America, Peru and Mexico and then brought by the Portuguese to Europe and Asia then spread throughout the world. Chili contains many compounds that are good for health, vitamin C, vitamin A, vitamin E, folic acid, flavonoid, phenol, capsaicin which can be used to treat malnutrition in society and non-infectious diseases such as heart disease, diabetes, cancer. The content of the nutrition depends on the genotype, environmental conditions, and the fruit ripening phase at harvest. In Indonesia, there are many local varieties or landraces of chili that have adapted well to the local environment. Local varieties are good genetic resources for developing new superior varieties of chili that have the quantity, quality, and resistance to environmental stress.

Abstract

Chili (Capsicum annum) is one of the horticultural commodities that has an important role in human life and Indonesian chili plants have important economic value and occupy second place after beans. Meanwhile, in East Java, chili commodity production in 2013-2017 reached 440 tons and one of the highest contributors was Ringinsari, Kandat, Kediri. However, the increase in chili commodities in the village has so far been strongly influenced by the presence of the fungi pathogen is Fusarium oxysporum f.sp.capsici that cause wilt disease, can reduce production on average up to 75 % and cause the plant to die. The control of that pathogen generally uses chemical control that hurts humans and the environment so until now it have not been satisfactory. Depend of that it needs alternative control using endophytic bacteria that are formulated in organic fertilizer as biological control. Endophytic bacteria are group of bacteria that live in plant tissues without causing negative effects, including not causing plants to get sick and having a mutual relationship with their host plants. Endophytic bacteria can be found in various plants including agricultural crops and can be isolated from all parts of the plant, namely roots, stems, leaves, and seeds. Endophytic bacteria produce secondary metabolites and compounds that can be used to induce plant health and growth. Endophytic bacteria produce fenol, flavonoid that increase plant resistance to diseases and pests, improve plant health, phytohormones increase plant growth. The method stages of research are propagation of endophytic bacteria, manufacture of suspension of endophytic bacteria, mixing of suspension of endophytic bacteria into organic fertilizer, data analysis using analysis of variance and 5% BNT test. The results are Incubation period is slower, disease intensity decreases, and plant height increases.

Abstract

Corn (Zea mays) has an important role in the food supply in Indonesia, as the second commodity after rice and the second source of carbohydrates after rice which is a derivative of rice and is still considered feasible to meet national needs. The increase in national corn production is strongly supported by several corn production center provinces such as East Java and one of the districts that have the potential to support corn production in East Java is Jombang, but the reality the production experiences several obstacles, one of which is the presence of plant pest organisms (OPT). namely the fungus Peronosclerospora maydis caused by downy mildew. In the control of disease so far in the field, many use fungicides that are harmful to humans and the environment. The solution to reduce the use of fungicides is to utilize endophytic bacteria from eggplant and it has been formulated with organic fertilizer so that it is easier to apply to corn plants, this solution is expected to control disease rates, reduce losses, and improve corn plant health. The method used in community service in Mentaos, Gudo, and Jombang were situation analysis, problem identification, socialization that was attended by 25 farmers, and application of endophytic bacteria from eggplant plants in organic fertilizer formulas. The results obtained are that the people of Mentaos, Gudo, and Jombang were able to apply the endophytic bacterial formula in organic fertilizer with the sprinkle technique. The results show that the community can apply the endophytic bacterial formula, corn plants become healthy, and disease intensity is low.

Abstract

The babadotan plant is a weed plant that can be used as a vegetable insecticide because the chemical compounds contained in bandotan are saponins, flavanoids, polyphenols, coumarine, 5 percent eugenol, HCN and essential oils. The priority for agricultural development is food security, where food is followed by an increase in the amount of production to support the increasing population rate. National food availability can be influenced by several factors such as the presence of pests and the effectiveness of control. The presence of pests in crop cultivation areas can cause significant loss of agricultural production. S. frugiperda damages corn plants with a heavy attack rate, the larval population is between 2-10 per plant. This study aims to determine the use of babadotan as a vegetable pesticide to control S. frugiperda pests. This research was carried out in December 2021-January 2022 at the Plant Health Laboratory of the Faculty of Agriculture UPN "Veteran" East Java. This study used a non-factorial Completely Randomized Design (CRD), namely, S. frugiperda larvae and Babadotan Vegetable Pesticides with 3 doses of 200gr/l (P1), 300gr/l (P2), 400gr/l (P3) and Control (P0). The results showed that the application of the babadotan plant extract was effective in controlling the S. frugiperda caterpillar by giving a total mortality value of 100% in the P3 treatment (400 g/l concentration). Symptoms of larval poisons are marked by changes in color, namely at first the caterpillar is green to brown to black and there is mucus around the anus before it dies.
