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

Sustainable agriculture is not only limited to eliminating the use of agricultural inputs in the form of inorganic substances but in the form of utilizing local natural resources. The use of vermicompost and refugia plants is an alternative in organic farming. The purpose of this study was to determine the use of vermicomposts and refugia plants as inputs for organic farming in lowland rice. The study was carried out on a paddy pond in the village of Kuluran, Kali Tengah, Lamongan. The study used a randomized block design with treatment giving 20 tons ha-1 kascing and refugia plants on (P0) without chemical fertilizers, (P1) with the addition of 562.5 kg ha-1 NPK, (P2) adding 375.0 kg ha-1 NPK, (P3) addition of 187.5 kg ha-1 of NPK and (P4) addition of 750.0 kg ha-1 of NPK. All treatments were repeated 3 times. The results showed that the application of vermicompost treatment of 20 tons ha-1 and refugia plants without organic fertilizer gave the highest yield at the final plant height (118.61, cm) and the production of wet rice (13.28 tons ha-1).

Abstract

With the large need for organic fertilizer in fulfilling agricultural cultivation, vermicompost is a fast and appropriate way to utilize local natural resources in meeting the needs of organic biological agents. This study aims to determine the effect of giving organic fertilizer kascing with biological dimensions and chemical fertilizers (Urea, KCl, KNO3 Merah, and Phonska) with indicators of shallot plants. The study was conducted using a randomized block design, with the treatment of giving biological fertilizer with a dose of 30 tons/ha combined with chemical fertilizer with a dose (Urea 200 tons/ha; KCl 200 tons/ha; red KNO3 200 tons/ha, and Phonska 200 tons / ha Ha). The treatments P0 (without chemical fertilizer), P1 (25% of the dose of chemical fertilizer), P2 (50% of the dose of chemical fertilizer), P3 (75% of the dose of chemical fertilizer) and P4 (100% of the dose of chemical fertilizer). The results showed the availability of P-soil and C-organic soil after treatment were not significantly different. Observation of plant height also shows unreal results. While the number of tubers and production results obtained P2 gives the highest yield and is significantly different from other treatments.

Abstract

Community service, concerning the development of organic Pamelo Tourism Village based on biopesticides, has been carried out in Tambakmas Village, sub-district Sukomoro, Magetan Regency. Pamelo (Citrus maxima) has potential to be developed due to its ability to grow in tropical area and its raising production. Tambakmas Village in sub-district Sukomoro, Magetan, is one of the Pamelo production areas. Stem rot, caused by Botryodiplodia theobromae which is often happened to Pamelo trees in Tambakmas village, might reduce the quality and quantity of the harvest. However, the use of chemicals to prevent stem rot must be avoided to preserve the environment. Therefore, the development of Pamelo Organic Tourism Village requires biopesticide-based organic agriculture to restrain the disease. The socialization of biopesticide-based organic pamelo cultivation has been carried out to the Pamelo farmer group in Tambakmas Village from May to July 2019, it was integrated disease control including weeding, pruning, preparing and sterilizing the soil, and application of biopesticides. The severity of stem rot disease in Pamelo trees on the observation land with integrated disease control was examined and compared to the trees on the farmers' land without integrated disease control. Results of the observation land with integrated disease control showed that the disease severity slowly decreased by 16.20%. In contrast, disease severity that happened in the land without integrated disease control increased by 5.8%. Besides, the Pamelo trees that were treated with biopesticide developed a wound healing from the stem rot disease and exhibited growth of shoots on the treated region.

Abstract

This study aims to explain and explore government policies and the competitiveness of processed cocoa to the welfare of cocoa farmers in East Java. The research method uses quantitative descriptive analysis with the Revealed Comparative Advantage (RCA) method, and the approach of the Minister of Agriculture of the Republic of Indonesia Number: 67 / Permentan / ot.140 / 5/2014 concerning the quality and marketing of cocoa beans. The population of this research is Smallholder Cocoa Farmers in 9 regions of East Java with 45 respondents through indicators: the performance of cocoa farming, cocoa farming income in meeting the needs of spending on the production of facilities and infrastructure for cocoa farming, basic expenditure, education, social, communication, recreation, transportation, home care, and health costs. The results showed that the comparative advantage of East Java cocoa based on the results of the calculation of competitiveness (RCA), for processed cocoa commodities valued> 1 in 2015 - 2017 which means that processed products of East Java have competitiveness, then in 2018 the results of the RCA showed a value < 1, which means that East Java processed cocoa products do not yet have competitiveness in the national market. Through the Government Policy approach (Permentan no: 67 / Permentan / ot.140 / 5/2014) shows that all cocoa farmers in Blitar, Mojokerto, Trenggalek, Ponorogo, Pacitan have implemented cocoa cultivation following the implementation of cocoa post-harvest handling guidelines. Whereas in Malang, Nganjuk, Madiun, Jombang regencies have not consistently applied guidelines for handling post-harvest cocoa. The level of welfare of cocoa farmers shows that Blitar, Mojokerto, Trenggalek, Ponorogo, Pacitan districts consistently have a high level of welfare compared to Malang, Nganjuk, Madiun, Jombang districts that have not consistently improved the welfare of Cocoa farmers.

Abstract

Taman Sari Village, Licin District is a developing village with an IDM value of 0.695. This means that efforts are needed to improve the level of the village economy as well as community welfare so that it becomes a developed and independent village. The determination of the IDM Value is determined using indicators and scoring. Viewed from the aspect of social security (IKS) there are still some weaknesses both in terms of health dimensions, human resources in the health sector; and from the educational dimension, namely the unavailability of advanced education, and in terms of variable access to knowledge. From the social aspect there are no obstacles, so too from the aspect of religion, and tolerance, and public space. But from the environmental aspect, especially the optimization of agricultural land is very limited so it still needs to be improved.

Abstract

Cultivation of urban vegetables using the aquaponic system can be taken into consideration in future agriculture because fish manure and fish food residues can become nutrients for plants after being modified by probiotics. The study aims to analyze the ability of various probiotics in decomposing fish droppings into nutrients available for growth of kale plants (Ipomoea aquatica) in aquaponic cultivation systems. The study was conducted at the Greenhouse UPN Veteran in East Java using a completely randomized design with four treatments: 1) without probiotics (A1), 2) A2, 3) A3, and 4) A4, and each treatment was repeated three times. Control is carried out by planting kale on soil media. The results showed 1). Kale plants planted with aquaponic systems have poor growth compared to those planted using soil media. 2). Probiotics used in the treatment for catfish farming do not affect kale plants. 3) The use of Probiotics (A2, A3, and A4) affects the growth of fish weight better than without the administration of probiotics (A1)

Abstract

One alternative for suppressing disease and promoting plant growth is to use the formula for biological agents. The research aims to determine the best formulation of Pseudomonad fluorescent Pf-122 and to determine the right application time in stimulating the growth of chili plants. The formula is made by mixing bacterial active ingredients with semi-natural media of rice crab by hydrolyzing using pineapple and papaya, as well as organic fertilizer. The study used 2 treatment factors. The first factor is the type of formula consisting of control using only Pf-122 (F0), Pf-122 + K (rice crab) (F1), Pf-122 + KN (rice crab by hydrolyzing using pineapple) (F2), Pf-122 + KP (rice crab by hydrolyzing using papaya) (F3). The second factor is application time; watering five days before planting and watering while planting. The results showed that plant growth, namely plant height, number of leaves, root length, and root weight did not differ statistically significantly from all treatment types of application. When viewed from the time of application of the formula, there is also no difference in the growth of chili plants. However, when viewed from the average value, the control without formula tends to show a lower growth value compared to that given the formula. In the generative growth phase, which is when the flowers appear, the chili plants are given a formula faster than without the formula. Application for all types of formulas, the time of occurrence of flowers is not significantly different. The number of Pf-122 populations in the rhizosphere decreases and increases are unstable in all formula applications. The high Pf-122 population in the rhizosphere does not show high chili growth either
