Effect of sugarcane by-product (filter cake) and zeolite application on the growth of sugarcane nursery plant Department of Soil Science, Faculty of Agriculture, Hasanuddin University Abstract A problem in sugar factories after processing of sugarcane to produce sugar is the solid waste i.e. filter cake which can be reduce environmental quality. Utilization of this material combined with zeolite could be applied as bioremediation for the growth of sugarcane. This study aims is to determine the effect of filter cake and zeolite on the growth of sugarcane nursery plant. This study used a randomized block design with 9 treatments. The treatment combination was repeated 3 times in order to obtain 27 experimental units. The results showed that the addition of filter cake sugar factory waste at a dose of 7 ton/ha combined with zeolite without heat treatment of 500 kg/ha significantly increased growth in sugarcane plant height, as well as improved soil chemical properties in pH, CEC, and K parameters. 3.5 ton/ha combined with zeolite without heat treatment of 500 kg/ha had a significant effect on the parameters of plant dry weight and root dry weight, and improved soil chemical properties of C-Organic parameters. Filter cake 3.5 ton/ha combined with heat treatment zeolite 500 kg/ha significantly affected the number of leaves and stem diameter parameters of sugarcane. Filter cake 7 ton/ha combined with heat treatment zeolite 500 kg/ha had a significant effect on the available P parameter and total N. Application of filter cake and zeolite can increase the growth of sugarcane nursery plant. Keywords: Sugarcane, filter cake, zeolite, cation exchange capacity, bioremediation.
