Abstract

The study aimed to determine the response of Brazilian spinach plants to the application of water hyacinth (Eichhornia crassipes) compost and goat manure with LED and fluorescent artificial light. The research was conducted at KP2 Instiper in Maguwoharjo, Depok, Sleman from April to June 2022. The research used an experimental method with a split-plot design. The main plot in the form of artificial light consists of 3 types, namely: Control (sunlight), 18 Watt Neon Lights, and 36 Watt LED Lights. The subplots consisted of 3 types of organic fertilizers, namely: Control (without fertilizer), water hyacinth compost, and goat manure compost, so 3 x 3 = 9 treatment combinations were obtained, each with 3 replications. Based on the results of the research conducted, it can be concluded that the combination of various light sources and various organic fertilizers affects the growth of Brazilian spinach (Alternanthera sissoo). The growth and biomass of Brazilian spinach in a combination of sunlight and 36 Watt LED lights with water hyacinth compost and goat manure was better than the growth and biomass of Brazilian spinach in a combination of 18 Watt fluorescent lights with various kinds of organic fertilizers. There is a positive correlation between the crown and root biomass. Sunlight and LED have a light intensity that is more suitable for the growth of Brazilian spinach compared to fluorescent lamps.

Abstract

  Organic rice farming is a cultivation activity that is synonymous with labor-intensive activities. The use of internal inputs in organic rice farming requires time and effort to prepare. Organic farming is a low-cost farming activity because the use of internal inputs makes organic rice farming more profitable. The purpose of this study was to analyze the level of allocative and economic efficiency of organic rice farming in Lampung Province. Economic and allocative efficiency analysis is carried out by deriving the dual frontier cost function from the Cobb-Douglas Stochastic Frontier production function. The results showed that organic rice farming in Lampung Province was not allocatively efficient. Farmers have not maximized the use of organic seeds and pesticides, where both production factors have a low price allocation. Organic rice farming in Lampung Province is not yet economically efficient. Farmers have not received the maximum revenue from organic rice farming. Most of the organic rice harvested is consumed by farming families, so not all organic rice harvested generates income.

Abstract

This study aimed to determine the effect of rice husk organic fertilizer on increasing the amount of infiltrated water and its correlation to sorghum yields. The use of organic rice husk fertilizer also minimizes rice husk waste. The research method used a randomized block design consisting of two factors, the variety and organic fertilizer factors. The variety factor consisted of 2 levels, namely the Numbu variety (V1) and the Kawali variety (V2), while the dose factor of organic fertilizer consisted of 3 levels, namely without the application of organic fertilizer (P0/control), 25 tons.ha-1 (P1) , and 50 tons.ha-1 (P2). Parameters observed at the end of the experiment included measuring soil physical properties, namely infiltration using a double ring infiltrometer, and measuring sorghum yields. Data analysis was performed by analysis of variance (ANOVA) with further tests using the Tukey test (5% BNJ). Correlation analysis was conducted to see the relationship between organic fertilizer dosage and seed weight per hectare with constant infiltration. Infiltration data from field measurements is processed to create an infiltration curve by modeling following the formula developed by Horton f = fc + (fo – fc) e-kt. The results of infiltration modeling based on the Horton model can be seen in the infiltration curve which shows that the P2 rice husk organic fertilizer produced the highest curve line compared to P1 and P0/control. The results of statistical analysis with the 5% BNJ test for constant infiltration showed that the P2 and P1 rice husk organic fertilizer treatments provided the same infiltration capacity, but the infiltration capacity values for the P2 and P1 rice husk organic fertilizer treatments were higher compared to P0/control. There is a very strong positive linear correlation between the dose of organic fertilizer and the weight of seeds per hectare with a constant infiltration value.

Abstract

The use of certified seeds can increase productivity and technical efficiency of garlic farming. This study aimed to examine the effect of using certified seeds on the technical efficiency and productivity of garlic farming. This study uses secondary data in the form of cross-sections from the Horticultural Plant Household Survey (SHR, 2014) conducted by the Central Bureau of Statistics (BPS). The number of samples used is the same as the number of SHR 2014 samples. These data were analyzed using stochastic production frontier sample correction (SC-SPF) combined with propensity score matching (PSM) to eliminate observed and unobserved biases. The average treatment effect on the treated (ATET) used to directly calculate the effect of using certified seeds on productivity and technical efficiency. The average productivity of farmers using certified seeds was higher than that of farmers who did not use certified seeds. Meanwhile, the average technical efficiency (ET) of farmers who use certified seeds is lower than that of farmers who do not use certified seeds. This shows that the use of certified seeds has no effect on the technical efficiency of garlic farming. There are two alternative policies that can be taken, the first is advising farmers not to use certified seeds or the second alternative is improving the mechanism for distributing garlic seed assistance and developing the garlic seed industry.
