Utilization of Wastewater and Filter Cake from Sugarcane Factory for Corn Cultivation

Abstract

This research aims to apply the waste from the sugar factory to the benefits of agriculture by using
wastewater from the 1st, 2nd and 3rd facultative ponds (FP) of stabilization pond treatment system and filter
cake (FC) including using pig manure (PM) instead of chemical fertilizer for Hi-brix 3 sweet corn cultivation.
The nineteen experimental treatments were designed by completely randomized design (CRD) at rates of
CF from 25 to 0 kg/Rai and in different FP wastewater. The results revealed that the same FP wastewater
at rate of 20 kg of CF/rai gave the best productivity. Moreover, the analytical results of soil after planting
showed that pH, organic matter, total-nitrogen, of all treatments which using FC and PM were higher than
the control treatment which only used CF 25 kg/Rai. Thus, FC and PM were soil amendments and reduced
the soil degradation. Therefore, the FP wastewater could be used replace natural water and FC and PM
could be used replace CF in corn cultivation.
