The aim of research is to test the combination of organic fertilizer and NPK fertilizer, test organic fertilizer, test NPK fertilizer that is suitable for the growth and yield of sweet corn. This research method using Randomized Block Design (RAK) arranged factorial consists of two factors, namely Organic Fertilizer (cage) with 3 levels of treatment (K) and NPK Fertilizer with 3 levels of treatment (M). Each treatment was repeated 3 times and each treatment combination consisted of two sample plants. The results of this study showed that the overall treatment of the combination of organic fertilizer and NPK fertilizer on the growth and yield of sweet corn plants did not show a real effect. Separately the treatment of organic fertilizer gave a very real effect on all observation variables, the average organic fertilizer as much as 17.5 tons / ha or 1.5 kg / tan (K3) gave the highest growth and yield of sweet corn compared to other treatment, Separately the treatment of NPK fertilizer gave a very real influence on all observation variables, the average NPK fertilizer with a composition of 450 kg Urea + 150 kg TSP + 75 kg KCl) / Ha or 9 g + 3 g + 1.5 g / tan (M3) gives the highest growth and yield of sweet corn compared to other treatments.

A narrow land farmed urban Agriculture. It used for daily fresh vegetables and fruit for the housing community in urban areas. Portable Urban Agriculture Technology as a support facility to increase production of Urban Agriculture, the Greenhouse portable system could be built and transferred to a specific location is convenient, safe, fast, lightweight structural material (PVC 0.55mm Tarpaulin) so that the Urban Agricultural Products closer to residential consumers in urban. The impact was the price was cheaper but quality. The objective was to plan, build and test prototype Water inflated tent activity as a facility to strengthen Greenhouse's strength, speed, effectiveness and comfort. Application method stages of the Cup or SDN on a former tin mining land, with Portable Urban Agriculture Technology support soil nutrient drive are as follows: first Reconstruction of the land in the form of land arrangement in accordance contours and irrigation channels that exist in the field is very important to support the success of the method SDN; second Management of top soil in the form of top soil enriched with organic material will support environmental compliance in the soil, especially for the growth and development of VAM hyphae and root system; third Soil Amendment to improve the physical and chemical properties of former mining land; fourth Activities vegetation of mined land with SDN method optimizes the achievement of the goals replanting of sustainable of native vegetation for erosion and runoff, repair and restoration of biodiversity, landscape aesthetics that will impact habitat improvement fauna, biodiversity, soil productivity and water quality. Tree plant species such as Acacia mangium, Acacia auriculiformis and Leucaena diversifolia microbes that have been infected with mycorrhizal fungi (VAM) will be very effective and support this effort. Vegetation activities with SDN method includes the following steps: first Seedling plants with VAM; second Preparation of arable land that supports the development of VAM in the soil; third Planting of the first cup with VAM; fourth Incubate 1 month; fifth Planting of the second cup with VAM; sixth 1 month incubation; and seventh The planting of the main crop.
