Abstract

Low organic carbon and soil nitrogen content is one of the factors limiting Edamame productivity. This research aimed to determine the dose of cow manure and legin that produces the best growth and yield of Edamame soybeans. The experiment was carried out in Sinabun Village, Sawan District using a complete factorial randomized block design, with two factors, namely the dose of cow manure and legin. The research showed that a single dose of cow manure had no significant effect on the growth performance, yield, and soil fertility of edamame soybeans. Treating legin at a dose of 7.5 g.kg-1 seed can increase plant height growth and pod weight per plant.

Abstract

The research aimed to determine the effects of the potato and banana extract supplements in fresh form and flour with different measurements on the growth of plantlet orchid Dendrobium sp in vitro. Factorial Random Planning (RAL) consists of two factors: type of additive and measurement against 16 combinations of treatments, and five repetitions. In total, there are 320 samples of plants. Observations included the percentage of live plantlets, the start time of the shoots, the shoot height, the number of leaves, the root initiation time, the root number, and the root length. The results of the study showed that there was an interaction between the type of additive and the mark against the percent of living plantlets at age 4, 8, and 12 weeks, the height of shoots at age 8 and 12, the root initiation times, the count of roots and the length of the root. The growth percentage ranges from 80-100%, except for the potato flour additive 200 g/l of 45%. Potato and banana additives in the form of flour can increase the start time of the shoots faster than in the fresh form.

Abstract

This research aimed to observe the growth and production response of the Inpari 32 hybrid rice variety to the application of aloe vera liquid organic fertilizer and inorganic P fertilizer compared to the absence of the combination of these two fertilizers. The research method used was comparative, comparing rice field plots treated with a combination of inorganic P fertilizer (Phonsgreen) at a dose of 150 kg/ha and aloe vera liquid organic fertilizer (P1) at a dose of 6 liters/ha with rice field plots without the combination of the two fertilizers (P0). Parameters observed included plant height, number of tillers, number of productive tillers, panicle length, number of grains per panicle, grain weight per clump, and weight of 1000 grains. The results showed that aloe vera liquid organic fertilizer and inorganic P fertilizer could increase milled dry grain production by up to 29.9%.

Abstract

This research aims to determine the use of shallot skin liquid organic fertilizers on the growth of eggplant plants and determine the application of different doses to eggplant plants. The method used in this research used a factorial Randomized Block Design (RAK) with two factors where the first factor was eggplant variety M1: Mustang F1, M2 : LagunaF1, and the second factor was the dose of Liquid Organic Fertilizer (POC) shallot skin V0 : no POC shallot skins, V1 : 20 ml/L POC of shallot skins, V2 : 40 ml/L POC of shallot skins, V3 : 60 ml/L POC of shallot skins, V4 = 80 ml/L POC of shallot skins. The results showed that shallots skin POC on both varieties did not provide significant interaction. Shallots skin POC independently affected plant height and number of leaves, with the highest results in the V4 treatment with an average of 26.00 cm and 21.84 strands. While in the parameters of the result, the V4 treatment showed the highest results in fruit weight, namely 243.99 g. Onion skin POC can increase eggplant plant growth with the highest dose of 80 ml/L..

Abstract

This study aimed to determine the effect of biourin on the growth and yield of sweet corn (Zea mays Saccharata Sturt). This research was conducted at the Bengkulu Agricultural Instrument Standards Implementation Center (BPSIP). This research was carried out using a Completely Randomized Design (CRD), with four treatments of biourin liquid organic fertilizer. P0: Control (NPK fertilizer), P1: 50 ml/l water, P2: 100 ml/l water, P3: 150 ml/l water each treatment was repeated seven times.  The results of this study showed that the provision of goat biourin had no significant effect on the parameters of plant height (14 and 28 hst), the number of leaves (14, 28, and 42 hst), stem diameter (14, 28 and 42 hst), cob length, cob length without cob, the diameter of the cob with weighed cob, the diameter of the cob without weighed cob, crown wet weight, crown dry weight, root wet weight, root dry weight and which significantly influenced the parameters of plant height (42 hst), weight of the cob with weighed cob, and weight of the cob without weighed cob.

Abstract

The one pest that can potentially cause harm to fruit cultivation is fruit flies (Bactrocera spp). The fruit flies cause losses in qualitative and quantitative terms in Indonesia and are classified as Bactrocera. It is necessary to identify the diversity of fruit flies in Science Techno Park ( STP) University of Tribhuwana Tunggadewi and handle them. This research aimed to determine the types of fruit flies and how to handle them. The method used in this research is a systematic sampling method, by taking 1 sample at each point of the bottle trap is given an attractant. The results showed that there are found three species of fruit flies at the STP location. The three species of fruit flies found in the STP are Bactrocera dorsalis, Bactrocera carambola, and Bactrocera umbrosa. B. dorsalis has the highest abundance with 82.7%, followed by B. carambola at 16.3%, and the lowest is B. umbrosa at 0.8%. The highest dominance of the fruit fly species in the STP was B. dorsalis value D 0.82.

Abstract

This research aimed to determine the relationship between the subsidized fertilizer distribution mechanism and the success of farmers in adopting fertilization technology. This study used a descriptive method approach—data retrieval techniques using interviews, documentation, and observation. The mechanism for distributing subsidized fertilizers in Purwoasri Village, Singosari District  According to the results of the recapitulation of the subsidy fertilizer distribution mechanism, researchers explained that the distribution mechanism and technology adoption with the following percentages: subsidized fertilizer distribution mechanism 74%, the role of agricultural extension workers 76%, the role of farmer groups 79%, meaning that the distribution mechanism has been successfully carried out well, such as extension workers helping and guiding farmers in the preparation of RDKK (Plan Definitive Group Needs). Meanwhile, the adoption of 70% fertilization technology means that extension workers and farmers complement each other and work together to achieve the success of farmers in the successful adoption of fertilization technology in Purwoasri Village.

Abstract

This study aimed to explore the impact of Ramadan on chicken meats in East Java. The ARCH/GARCH model is used in this study to assess whether or not beef has a price. Next, the GARCH model is used to analyze the effects of price volatility and fluctuations in Ramadan on the price of chicken meat in East Java. The ARCH-LM test's findings show that price volatility impacts changes in chicken meat prices. Then, the estimation results for the GARCH (1,1) model show that the volatility from the previous period and the variation in East Java from yesterday affect changes in chicken meat prices. GARCH (1,1) model displays.
