Abstract

Cultured plants will adapt to new environmental conditions at the acclimatization stage. Changes that occur can observed through changes in morphological and anatomical structures.  The increase in the number of cells and the size of plant organs illustrates the process of changing the anatomical structure of plants. It is necessary to optimize the concentration of biostimulant given and see its effect on plant growth and anatomical structure, to explain the mechanism of action of biostimulants. The research aimed to determine the concentration of biostimulant cengkodok leaf extract on black orchid plants. The study used a completely randomized design consisting of 8 treatment levels of cengkodok leaf extract biostimulant concentration (0, 10, 20, 30, 40, 50, 60 and 70 mg/L).  The results showed that the concentration of cengkodok leaf extract 20 mg/L was the best concentration for the parameters of the number of leaves and the number of roots of black orchid planlets, respectively 2.5 leaves and 7.5 roots. The application of cengkodok leaf extract affects the anatomical structure characteristics of black orchids, including an increase in the thickness of leaf mesophyll tissue, stem cortex tissue, and roots.

Abstract

Knowledge of the traditional use of plants has been passed down from generation to generation by the Kulawi ethnic community in Salua village, Central Sulawesi. In this study, we document community knowledge about the effect of plants as medicinal plants, traditional ceremonies, food/drinks, and building materials. Based on the results of interviews and exploration, the plant that collected 25 species was found with local names, parts used, and how to use them. A total of 18 species can used as medicinal plants, five species for food/drink, one species for building materials, and three for traditional ceremonies. Our study recommends ex-situ management of natural resources so that plants can used sustainably.

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.

Abstract

The research aims to obtain the right type and dose of Liquid Organic Fertilizer to obtain optimal growth and yields of Pagoda mustard plants. The study used a factorial Completely Randomized Design, namely two kinds of Liquid Organic Fertilizer (cow urine and rabbit urine) and the dosage consisted of 4 levels (0, 600, 1.200,1.800 ml) so that there were 8 treatment combinations (P1D0, P1D1, P1D2, P1D3, P2D0, P2D1, P2D2, P2D3) and repeated 4 times. Observations include parameters: plant height, number of leaves, length, and width of leaves, diameter of the hood, wet weight of the plant, and dry weight. The research results showed that the type and dose of LiquidOrganic Fertilizer interacted with each other to support the growth of pagoda mustard greens, 1,200 ml/l cow urine liquid organic fertilizer produced the best growth. Both POC cow urine and rabbit urine produce insignificant fresh plant weight, and a POC dose of 1,200 - 1,800 ml/l was able to produce the best plant results.

Abstract

This study aimed to examine the effect of exogenous salicylic acid treatment and salinity stress on the morphology and seed yield of soybeans (Glycine max L.). The experimental design used a completely randomized design factorial with four replications. The first factor was Salicylic Acid with four different dosages, namely 0 ppm, 100 ppm, 200 ppm, and 300 ppm. The second factor was Salinity Stress with two levels, 0 dS/m, and 5 dS/m. The observed parameters were root volume, plant height, total leaf area, root shoot ratio, and seed weight. The result showed that plant height, total leaf area, root volume, and root-shoot ratio were not significantly affected by salicylic acid treatment. Seed weight showed an increase in salicylic acid treatment. Salinity stress reduced all morphological size and seed yields of soybeans significantly.

Abstract

The research aims to determine the effect of the type of substrate and concentration of AB Mix on the results of kailan plants.  The research used a completely randomized design with eight treatment combinations, four replications, and three samples in each replication. The treatment combination are S1K1 (wood powder and AB Mix 4 ml/l); S2K1 (Sphagnum and AB Mix 4 ml/l); S3K1 (husk charcoal and AB Mix 4 ml/l); S4K1 (Cocopeat and AB Mix 4 ml/l); S1K2 (Wood powder and AB Mix 6 ml/l); S2K2 (Sphagnum and AB Mix 6ml/l); S3K2 (Charcoal husk and AB Mix 6 ml/l) and S4K2 (Cocopeat and AB Mix 6 ml/l). The results showed there is an interaction between the type of substrate and the concentration of AB Mix on the wet weight of the plant (your crop yield). The highest plant yields were obtained using husk charcoal substrate and AB Mix 6 ml/l. The husk charcoal substrate can produce the highest leaf area, but AB Mix 4 - 6 ml/l can not affect plant growth.

Abstract

The research aims to obtain the type of substrate and dosage of AB Mix that can elevate the growth of pagoda mustard plants. The study used a completely randomized design with four substrates: wood powder, charcoal husk, sphagnum moss, and cocopeat. AB Mix uses two doses such as 6 and 8 ml/l repeated 4 times in each experiment with three plant samples. Observations included parameters of plant height, number of leaves, leaf area, wet weight of plants and roots, and dry weight of plants and roots. The results showed that the husk charcoal substrate with AB Mix 8 ml/l nutrition produces the highest wet weight of pagoda mustard plants.

Abstract

The objective of this study was to determine the level of technical, allocative, and economic efficiency in the utilization of production factors in shallot cultivation in Toronrejo Village, Junrejo District, Batu City. Data analysis was performed using Cobb-Douglas analysis. The results showed that the utilization of production factors simultaneously affected the production of shallots. The utilization of production factors of organic fertilizer partially affected the production of shallots. The average efficiency value of utilizing inputs such as land, seeds, organic fertilizer, inorganic fertilizer, labor, capital, and pesticides was 0.9981566. This means that the utilization of production factors must be technically efficient. The efficiency values of production factors such as land, seeds, organic fertilizers, and capital are greater than 1, which means that the means of production were not allocatively efficient. The use of production factors such as inorganic fertilizers, labor, and pesticides have efficiency values of less than 1, which means that they were not allocatively efficient. The production factors of land, seeds, organic fertilizers, and pesticides are not financially efficient, and inorganic fertilizers, labor, and capital are also not financially efficient.
