The research on the effect of adding tempe flour and time of prolong boiling on the quality of the oyster mushroom sausage ( pleurotus ostreatus) with Design Random Complete Method with two (2) replications. Factor I is the concentration of tempe flour that is: K1=5%, K2=10%, K3=15%, K4=20%. Factor II is long boiling (L) consisting of four levels, that is: L1 = 15 minute, L2 = 20 minute, L3 = 25 minute, dan L4 = 30 minute. The parameters observed: protein, water content, texture, organoleptic aroma and flavor. The statistical analysis was obtained, that Consentration tempe flour providing highly significant effect (P<0.01) to protein, water content, texture, organoleptic aroma and flavor. The long boiling providing highly significant effect (P<0.01) to water content, texture,organoleptic aroma, and flavor and had no significant effect (P>0.05) to protein.Keyword: Sausage, Oyster Mushroom, Tempe Flour, Time of Prolong Boiling

Poverty rice farmers is an actual problem that is being surrounded people who need to look for solution of the problem and strategies to overcome them. Still encountered problems in implementation, so that the rice farmers in the village Tukka District of Central Tapanuli still poor, can not meet all the basic needs as clothing, food and shelter. This study aims to reveal and analyze the factors causing poverty rice farmers. The results showed that poverty rice farmers in the village Tukka caused by the mental attitude of the farmers themselves, the lack of agricultural inputs and the lack of government incentives system, so the production and quality of the crop continued to decline, which in turn will lead to lower income farmers.Keywords: Farmers paddy, poverty, income

Dissemination is the activity of action-reaction not only affects the mindset of the target group but can also be the person who brings the innovation itself. The notion that the new dissemination carried out after the completion of the research process, in principle needs to be changed. Dissemination process has to take place during the research process begins proportionally. This study aims to identify the potential, constraints, and opportunities for the development of rainfed lowland rice through the approach of Integrated Crop Management, an innovative approach in order to increase the efficiency of paddy rice by combining various technology components, including specific technologies that support each other with regard to the use of resources wisely nature that impact the growth and productivity of plants. The method used is to assess the needs and opportunities of rainfed rice farmers in the WKPP Paya Itik Desa Nogorejo. Based on the research needs and opportunities then drafted the main technological packages which are then studied and practiced together between farmers, researchers and agricultural extension as a facilitator, to conduct a demonstration plot of 1 Ha. The results showed that the main obstacle to scale farmers first priority is the seed, and the productivity of rainfed rice integrated crop management approaches have increased an average of 1.1 tons / ha (tile), with the value of B / C ratio 1, 42.Keywords: Rice Rainfed , Integrated Crop Management , Productivit

UTILIZATION HARVEST WASTE AS ORGANIC FERTILIZER BY COMPOSTING ON PADDY FARMER GROUP AT HUTAGAOL PEATALUN VILLAGE, BALIGE KABUPATEN TOBA SAMOSIR Dermawan Hutagaol; Aisyah Lubis; Nurma Ani

Paddy sawah cultivation that done for long time used chemical fertilizer with dosage that continously increased but many reports indicated no respond on increasing paddy production. Utilization of chemical fertilizer caused decreased soil quality, which fertilizer respond was less that indicated by production that hard to increase while fertilizer dosage was increased every year so farm cost more expensive especially for buy fertilizer. This problem must be solved by applicated res earch result for farmer with utilized harvest waste as organic fertilizer by composting. This IbM activity aim was to used harvest waste as organic fertilizer by composting to decrease fertilizer cost and farmer income be increased. This activity target was found IPTEKS for farmer how processes to made harvest waste be organic fertilizer by composting to increased fertilizer efficiency so that chemical fertilizer can decreased. This activity result after socialized about utilization and composting processes was farmer understood and could made compost from harvest waste and increased farmer knowledge abaout utilization harvest waste as organic fertilizer.Key words: compost, farmer, harvest waste

The 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 bunches
