Abstract

The purpose of this two-year research is to find methods and theories of soil cultivation for the Medan city drainage sediment which makes the city drainage shallow. Improving the environmental quality of Medan city by cultivating trench sediment soil into a horticultural planting medium. Obtaining a neat, comfortable and helpful city condition for the Government, especially the Public Works Office of Medam City. It will be avoided from flooding due to smooth city drainage and clean environment. The results of the study can be concluded that the activated charcoal treatment is used from a number of activated charcoal ingredients (Coconut Shell, Wood Sawdust Waste and Kendaga Karet) with measurement criteria namely char yield, water content, ash content, volatile content, carbon fish power, iodine absorption from as a whole it has a good value to be used as activated charcoal which has a value above the minimum limit, namely water content below the maximum value (<15%), ash content <10%, carbon binding capacity> 60%, evaporation power <25% and iodine absorption. > 750 mg. All of these parameters are in accordance with the national standard of SNI 06-3730-1995. The second conclusion is that the absorption of metals to heavy metalsPb, Cd and Cu, has a good ability even though it is small because the metal content from the start is below the quality standard, the concentrations tested are 0, 1, 3, 5, 7, and 9. While the best is obtained of the reduction rate in heavy metal Cd, and is 7 grams / kg of soil sample.Keywords:

Abstract

The waste of tea powder is abundant and has not been widely used optimally. The alternative use is to use the waste as an additional medium or substitution for the white oyster mushroom growing media. The purpose of the study was to determine the effect of mycelium growth and the production of the fruit of the white oyster mushroom on combination media / tea powder substitution with sawdust. The research design used was a completely randomized design (CRD) with 4 replications. Combined treatments were M0 = 100% sawdust; M1 = 100% Tea waste powder; M2 = 75% tea powder + 25% sawdust; M3 = 50% tea powder + 50% sawdust and M4 = 25% tea powder + 75% sawdust. All treatments used the composition of the manufacture of mushroom growing media consisting of each combination of treatments, bran 10% by weight of the material and lime 0.5% by weight of the material. The parameters observed were the growth of white oyster mushroom mycelium, the rate of mycelium growth, the time the mycelium closed the substrate, the time of appearance of the fruiting body, the weight of the fruit body and the diameter of the fruit hood. The results showed that all parameters differed significantly. The best treatment is in treatment M4, followed by treatment of M3, M0 and M2.
