- W2258847488 abstract "Corn was the common crop in Kelurahan Sungai Tiung, Kecamatan Cempaka, Kabupaten Banjar, South Borneo. Corn was a main food. It easily adapted to changing climate and soil conditions and its productions were not sufficient to meet the inhabitants' need. The sludge from diamond-washing sludge was not intensively treated and was easily thrown away. As a result, surrounding environment was destructed / polluted.This research was trying to determine the quality of diamond washing sludge in Kelurahan Sungai Tiung, Kecamatan Cempaka, Kabupaten Banjar, which could be thrown away to agricultural area. The specific aims were to find the facts about the effect of the diamond-washing sludge to corn crop growth and productivity, to analyze the economic loss due to sludge application, and to analyze the effect of metal constituents in the sludge to soil and crop quality. This research used group random design (RAK) with five treatments each done three times. Diamond-washing sludge concentrations used were 0% (as a control), 25%, 50%, 75%, and 100%. Measured parameters were plant height, stem diameter, leaf area, seed weight, corncob weight, and plant dry weight. Deeper analyses were made with determining Leaf Area Index (ILD), Net Assimilation Rate (LAN), and Relative Growth Rate (LTR).Results of this research showed that the use of diamond-washing sludge with concentration of more than 25% had significant negative effects on the growth and productivity of the corn crop. The use of sludge concentration of more than 25% postponed crop growth for 20 to 25 days. The use of sludge on a 350 Ha area of corn crop cost a loss of Rp 1,022,478,475. The metal and non-metal constituents in the sludge decreased soil and plant (corncob) quality. Heavy metals (Pb and Cu) were 90% absorbed by corn crop and were mostly accumulated in the root tissue." @default.
