ANALYSIS OF INTEGRATION OF CASSAVA AGRIBUSINESS SUBSYSTEM AT PANCUR BATU SUB-DISTRICT DELI SERDANG REGENCY
Get PDFThis research aims to; a) knowing the constraints of cassava agribusiness development in the District Pancur Batu, b) determine the condition of the relationship between sub-systems that play a role in agribusiness of cassava in District Pancur Batu, c) determine the condition of the marketing of cassava in District Pancur Batu. This research was conducted in the District of Pancur Batu, with descriptive analysis method. Based on the research concluded; a) The condition of farm production of cassava in District Pancur Batu categorized quite good, but not yet showing the development of production. Cassava been farming community as an activity for easy maintenance process and does not require intensive care, b) the marketing conditions cassava is still modest and relatively fixed. Market chains are short so that share margin the biggest can be obtained by the manufacturer, c) Relationship between the subsystems of agribusiness cassava distinguished relationship is not tight and continuous on subsystem providers the means of production by farmers and relationships that continuously into sub systems production, marketing and processing because there is a relationship mutually beneficial. Based on the results suggested; a) government Deli Serdang undertake training and extension to farmers to increase farm production of cassava, b) the government of Deli Serdang provide incentives to farmers to stimulate an increase in farm production of cassava in District Pancur Batu, c) the government of Deli Serdang attention to marketing conditions cassava, by providing information and of action clear to the farmers market in the district of Pancur Batu.Keywords: agriculture, agro-industry, cassav

FLOUR TREATMENT OF OYSTER MUSHROOM (Pleurotus Ostreatus) AND OLD DRIED NOODLES DRYING ON QUALITY OF WHEAT MOCAF (Modified Cassava Flour)
Get PDFNoodle is one of the many popular food especially for the Indonesian people. Noodles made from wheat flour which is still imported by Indonesia. It is required to replace wheat flour. Alternative materials that can be used is mocaf. Mocaf has characteristics like wheat flour. The weakness of Mocaf is the absence of gluten and low protein content, therefore it needs to be added by source of protein like white oyster mushrooms.This research aimed to determine the effect of oyster mushroom flour and drying time on the quality of dried noodle from Mocaf. This research used a Rancangan Acak Lengkap (RAL) consisting of two factors, first is the addition of oyster mushrooms flour factor (5%, 10%, 15%, 20%) and second is drying time factor (20,40,60,80 minutes). Based on this research the best treatment of organoleptic properties was addition of oyster mushroom flour 5% and 20 minutes drying time, while in terms of chemistry at the addition of oyster mushrooms flour 20 % and 80 minutes drying time.Keywords : drying time, dried noodle, mocaf, oyster mushrooms flour
GRANTING MYCORRHIZAL AND SLUDGE TO INCREASE PRODUCTION PLANT OF PEANUT (Arachis hypogaea L)
Get PDFGiving mycorrhiza can improve nutrient uptake P plant, while Sludge can fertilize the soil. The use of organic fertilizer such as sludge has many benefits when applied in fertilizing agricultural crop land. The emphasis on the use of organic fertilizers continuously and sustainably will provide advantages and benefits in the long-term use. This study aimed to evaluate the response of groundnut crop production due to the provision of mycorrhizal and sludge as well as their interactions.The research was conducted at the experimental station road.Bunga Ncole XXII. Victory Urban Village Farmers. Tuntungan district of Medan, North Sumatra Province in April to August 2015. The material used is peanut seeds varieties bison, mycorrhizal, sludge.The design used was a randomized block design factorial with two treatment factors. The first factor sludge (S), which consists of 4 levels, namely: S0 = 0 g / plant (without giving sludge); S1 = 90 g / plant; S2 = 180 g / plant and S3 = 270 g / plant. Factors to two mycorrhizal administration consists of three levels ie: M0 = 0 g / plant (without giving mycorrhizae); M1 = 10g / plants; M2 = 20 g / plant. The parameters measured were Number of pods per plant (pod), weight of 100 grains dry beans (g) and uptake of plant nutrients P (%). The results obtained for the provision of mycorrhizae show a marked influence on the weight of 100 grains dry beans with the highest production are on M2 (70.50 g) while the parameter Number of pods per plant and plant nutrient uptake P showed no significant effect. Giving sludge showed significantly different influence on the parameters of the dry weight of 100 grains dry beans where production is highest in the S2 (68.22 g). while for the parameter Number of pods per plant and plant nutrient uptake P showed no significant effect. Interactions between giving mycorrhizal and sludge shows the real effect on nutrient absorption parameter P S1M2 plants where the combination treatment (0.32%) showed the highest plant nutrient uptake P, while the parameter Number of pods per plant and weight of 100 grains 100 dry seeds showed different influences not real .Keywords: Mycorrhizae, Sludge, Peanut, growth

Get PDFThe research objective was to determine growth and yield of sweet corn through the application of organic manure and compost cow urine oil palm empty fruit bunches. This study was conducted in June 2015 to August 2015 in the research field Meteorology and Geophysics Agency (BMKG) subdistrict Percut Sei Tuan, Deli Serdang, with altitude 25 m above sea level. This study uses a randomized block design (RAK) factorial with two factors, namely Liquid Organic Fertilizer Urine Cow (S) with 4 levels, namely S0 = 0 ml/tanaman, S1 = 40 ml / plant, S2 = 80 ml / plant and S3 = 120 ml / plant. The second factor is a factor Compost Oil Palm Empty Fruit Bunch (K) with 3 levels, namely K1 = 1.5 kg / plot, K2 = 3 kg / plot and K3 = 4.5 kg / plot. The parameters used in the study that plant height, number of leaves, stem diameter, days to flowering, weight cob with husk per plant, weight of cob without husk per plant, weight of cob without husk per plot, diameter cob without husk, length of cob without husk, and the number of rows per ear. The data were analyzed using ANOVA and continued with different test Mean according to Duncan (DMRT) with a level of 5%. The results showed that administration of liquid organic fertilizer of cow urine with dose 120 ml / plant)gave the highest growth in plant height, number of leaves, stem diameter, days to flowering and production weights cob without husk per plant, weight of cob without husk per plot, length cob without husk, the number of rows per ear, composting empty oil palm bunches dose 4.5 kg / plot gave the highest growth in plant height, number of leaves, stem diameter, days to flowering and production weights cob without husk per plant, weight of cobs without husk per plot, the length of the cob without husk, the number of rows per ear, while the provision of liquid organic fertilizer of cow urine at a dose of 120 ml / plant and compost empty fruit bunches of palm oil at a dose of 3 kg / plot gives the highest production on the weight of cob without husk per plant, giving liquid organic fertilizer cow urine at a dose of 80 ml / compost plants and oil palm empty fruit bunches at a dose of 4.5 kg / plot gives the highest production on the cob without husk weight per plot.Keywords: sweet corn , fertilizer liquid organic cow urine , compost oil palm empty fruit bunche
