Abstract

The research attempts to examine the effect of waters salinity and carbon organic total in the Lapindo Mud on the fluctuation of heavy metals Cu and Pb in the waters of Aloo Rivers. Sample is taken from Lapindo Mud from four different locations. Result of the characterization of Lapindo Mud shows that the clay and dust contents are 34-35 % and 39-46 %. Lapindo Mud texture is clay loam. The organic matter in Lapindo Mud is not surely increasing the concentration of heavy metal because there is oxide compound with great contribution to the increase of heavy metal concentration in Lapindo Mud. Result of TOC analysis indicates that the organic carbon ranges from 54.7 % to 55.47 %, Pb rate ranges from 0.27-0.34 mg/L, and Cu rate ranges from 0.83-1.31 mg/L. Indeed, Pb has higher metal flux in salt water at AL from 5x10-5 mg/cm2.hour to 9x10-5 mg/cm2.hour. Cu has higher metal flux in freshwater at SA1 2.3x10-6mg/cm2.hour to 8.71x10-5mg/cm2.hour

Abstract

Human?s increasing activity causes an immense increase in domestic waste. one form of domestic waste which could harm environment is vegetable waste. in this research, vegetables waste is used as based material of liquid compost. The process of producing liquid compost with vegetables waste as the base materials was using EM4 fermentation method as a starter and zeolite 80-100  mesh as the bind for soil nutrient in liquid compost. In the fermentation process, the researcher conducted 3 different behaviors in adding EM4 and Zeolite, in each 10 gr, 20 gr and 30 gr of EM4; and 40 gr, 60 gr and 80 gr of Zeolite. The fermentation process was conducted  in 40 days. The liquid compost samples were analized for pH, C-Organic, N-total, P-total and K-total. The results showed that highest concentrate of soil nutrient was from the adding of 30 gr EM4 and 80 gr Zeolite in which the result was 0.27% C- organik, 0,07 %  N-total, 0,04 % , P-Total dan 0,46 %  K-Total.
