Growth And Yield of Onion (Allium ascalonicum L.) Against Various Concentrations of Liquid Organic Fertilizer
Get PDFOnion (Allium ascolanicum L.) is not only popular as cooking spices in Indonesia but also throughout the world. Onion that has high economic value, has its own attraction to be cultivated by farmers. However, farmers often face some problems in onion farming. Problems were faced by farmers related to social economic conditions both internal, external and natural conditions. Fertilizer application for onion can use inorganic and organic fertilizer materials. The use of inorganic fertilizers without the addition of organic fertilizers over a long period of time, suspected to cause a decrease in soil physical and chemical capabilities, with the application of solid and liquid organic fertilizer is predicted to be more effective because the elements are more than one element. The use of fertilizers and organic matter through soil is often inefficient because of the fixation by soil particles. Liquid fertilizers administered overcome gapnutrients during growth. Herbafarm liquid organic fertilizer is a type of liquid fertilizer released by PT. Sidomuncul herbafarm which contains bio protectant, processed from by products of medicinal products made from raw medicinal plants and spices. Herbafarm contains macro and micro nutrients and also organic compounds that are essential for the growth and development of plants. This research was conducted in Sidera village, Biromaru sub-district, Sigi regency, Central Sulawesi Province. This study used a Randomized Block Design consisting of 5 treatment levels: P0 = control, P1 = 1 ml/liter of water, P2 = 2 ml/Liter of water, P3 = 3 ml/liter of water, and P4 = 4 ml/liter of water.

The Analysis of Economic Value on Irrigation Utilizationatrice Farming in Buahdua District, Sumedang Regency, West Java
Get PDFWater is a main factor on production input in rice farming. The need for water will increase as time progresses, but the availability of it is increasingly uncertain. One way to overcome the scarcity of water is the efficient using of water by determining the price of irrigation. This study aims to determine the price of water which is probably paid by farmers in rice farming, and to know the constraints faced by them. The research design used is quantitative descriptive. Primary data are obtained from 80 farmers taken by simple random sampling. Data analysis’ used here are analysis of descriptive, analysis of farming, and analysis of Willingness To Pay (WTP). The result of this research shows that the value of water rent in Buahdua Village is Rp. 4,428,031/ha/MT. Interviews show that almost all farmers are willing to pay the price of irrigation. The average value of PAP respondent is Rp. 61,813/ha/MT and the average value of TWTP is Rp. 28,751.891. Many obstacles faced by farmers in the use of irrigation is garbage, difficulty of getting water during the dry season, and damaged irrigation. This condition will affect the increasingly inefficient management of irrigation. Therefore, the economic value of water usage can be used as a reference asafees level by the farmers to reach efficiently
Callus Induction Of Cacao Clone Sulawesi 1 On Various Concentrations of 2,4 -D and Coconut Water Via in Vitro Culture
Get PDFCacao is one of important plantation crops grouped in the Sterculiaceae family. Sulawesi is the main area of cacao production and has a number of superior clones, such as Sulawesi 1 and Sulawesi 2. Based on data in 2012/2014 cacao production to consumption reached 174,000 tons, while in 2013/2014 was projected a deficit of 115,000 tonnes. Nonetheless, cacao agribusiness in Indonesia is still facing complex problems, among others gardener productivity is still low due to borer attacks cacao, the quality of products and the number is still low and still not optimal development of cacao products and providing superior amount of cacao seedlings. The primary problem of cacao production recently is low productivity. The main cause of low cacao productivity in Central Sulawesi is the use of inferior clones. To enhance cacao productivity, it is crucial to use cacao clones having high genetic potential via tissue culture or micropropagation techniques. The aim of this experiment was to assess the effect of different concentrations of 2,4-D and coconut water on the growth of cacao callus via in vitro culture. This experiment used Completely Randomozed Block Design in factorial patteren with treatments tested namely 2,4-D and coconut water concentrations. The concentrations of 2,4-D tested including 1 ppm, 2 ppm and 3 ppm, whilst coconut water concentrations tested consisting of 10%, 15% and 20%, and therefore there were 3 x 3 = 9 treatment combinations. Each treatment utilized 4 replications; and each unit combination used 5 explants (staminodia). Results of this experiment indicated that the addition of 3 ppm 2,4-D and 10% coconut water had a highly significant effect on the callus color 4 weeks after culture. The addition of 3 ppm 2,4-D in culture media showed a significant effect on callus color 4 weeks after culture, but had an insignificant effect on the callus formation, callus color 8 weeks after culture an callus texture. Supplementation of 20% coconut water had a significant effect on callus texture 8 weeks after culture, whilst the addition of 10% coconut water showed a significant effect on callus color 4 weeks after culture
Impact of Agricultural Sector Investments on Income Distribution and Poverty in Central Sulawesi, Indonesia
Get PDFCentral Sulawesi is a province in Indonesia with abundant natural resources particularly in agricultural sector. This condition suggests that the agricultural sector plays a very significant role in Central Sulawesi economy. One of the causal factors leading to the disparity of income distribution and poverty is investment allocation with its inconsistency occurs in sectoral development planningThe Gini Ratio of Central Sulawesi Province was 0.4844 in 2008 reflecting moderate level of income disparity for the income distribution among household groups. Simulation of increasing investment on agricultural and other sectors for 10% can generally decrease poverty at all groups of households both in rural and urban area. Simulation 2 (investment in plantation subsector) led to highest poverty decline as comparison to other simulation
