The beauty and benefits of plants in the Green Open Space are often disturbed by mistletoes. The existence of mistletoes often indicates the occurrence of disturbances or damage to the host plants that are parasitized. The mistletoes has been widely known by the community, but has never received attention in handling it. There has been little research on crop damage or loss caused by mistletoes. The purpose of this research is to know the existence of mistletoe and to know the pattern of distribution of mistletoe in green open space of Surabaya city. The study was conducted using the exploration method with emphasis to observe the distribution of mistletoes and identification of the type of mistletoe obtained. The results showed that the distribution of mistletoes in green open space in Surabaya tend to be grouped according to the distribution pattern of host plants. There are three types of mistletoes that mistletoe green open space plants in the city of Surabaya namely Dendrophtoe pentandra (L.) (very dominant), Macrosolen cochinchinensis (Lour.) Van Tiegh, and Henslowia frutescens.Champ

Siltation and the presence of water hyacinth plants on a sewer / river is a cause of flooding in urban areas (beaches). Plant fast-growing water hyacinth in rivers, ditches, Boezem, or area lakes and water storage areas, which impede the flow of water, encouraging a silting. Dredging rivers or reservoirs of waste water hyacinths just stacked on the edge of time that makes the environment become rundown. Implementation of the research aims to develop a composting technique made from water hyacinth in a mass scale. Factorial experimental treatment (1) Packaging: open, plastic bags (glansing), and buried; and (2) Starter: EM4, urea, and urea mixture EM4, so there are nine combinations of treatments. Experimental units are water hyacinth biomass as much as one cubic so that a total of nine cubic. Results of the study was to variable volume shrinkage, temperature, pH, change in smell, color and texture of the biomass of water hyacinth showed that during the first two weeks seen a high variation among treatments, but entered the week to five (four weeks after the starter) all variables are relatively homogeneous and shows indicators composting process is almost complete. Depreciation amounted to 68-78% volume, temperature 26-290C, pH of 7.0-7.5; texture is brittle, blackish brown color and relatively odorless. The C / N ratio of biomass at the composting mass of water hyacinth from Rp 33-37 (High), and at week five (four weeks after the starter) the results are varied, for the treatment of S1, S2B1, and S3B1 value is still above 20 (not yet decent) while the other is below 20, and the lowest at 16.9 S3B3 treatment.

Siltation of the river, ditches, reservoirs in urban areas is a problem because it causes flooding. The government annually undertakes dredging of the precipitate for the flow of water to flow smoothly. Soil sedimentary water potential to be utilized as a medium of planting in the development of urban agriculture. The research was conducted by survey method in Surabaya city waters. The sample was taken using random method of choosing, that is choosing condition of place environment and soil condition which is possible for planting medium. Soil sediment samples were observed for pH, color, structure, texture, organic matter content, Nitrogen (N-total), K2O and P2O5. The result of this research shows that all of the textured sedimentary soil content of clay is 89,87- 92,14%, organic material content is about 5,96-7,60%, total N-content is 0,09-0,13%, K2O content between 0,88-1,12%, and P2O5 content between 2,08-2,44%. The color of soil was grayish-black-black. The mud deposits of the housing sewer are the most crumbling and the most consumptive reservoir are sludge. Sewage soil sludge is potentially used as a planting medium in the development of urban agriculture.

Siltation and the presence of water hyacinth plants on a sewer/river is a cause of flooding in urban areas (beaches). Water hyacinth grows fast in rivers, sewer, boezem, lake and or water storage areas, which impedes the water flow and encourages a silting. Rivers dredging or reservoirs of waste water hyacinths just stacked on the edge of river that makes the dirty environment. The research aims to develop a composting technique made from water hyacinth in a mass scale. Factorial experimental treatments (1) Packaging B1: open, B2: plastic bags (glangsing), and B3: buried; and (2) Starter S1: mixture EM4 30%, S2: mixture EM4 20% + urea 1kg/3 liter, and S3: mixture EM4 10% + urea 2 kg/3 liter, so there are nine treatment combinations. Experimental units are water hyacinth biomass as much as one cubic, nine cubic overall. The research results devoted to volume shrinkage, variable temperature, pH, change in smell, colour and biomass texture of water hyacinth during the first two weeks showed a high variation among treatments, but in the fifth week, all of variables were homogeneous relatively and showed almost complete indicators of composting process. Depreciation amounted to 68-78% volume, temperature 26-29oC, pH of 7.0-7.5; texture is brittle, blackish brown color and relatively odorless. C/N biomass ratio at composting mass of water hyacinth from 33-37, and at fifth week the results are varied for the treatment of S1, S2B1, and S3B1 value is still above 20 while the other is below 20, and the lowest at 16.9 S3B3 treatment.
