Effect of Tapioka Liquid Waste on Growth of Ipomoea Reptans Poir Using Floating Raft Hydroponic Technique

Abstract

Tapioca industry is one type of industry that produces liquid waste that can cause pollution if not managed properly. To solve this problem, tapioca liquid waste can be utilized to produce organic nutrients for plants. The purpose of this research is to know the influence of tapioca liquid waste on the growth of Ipomoea reptans Poir. using floatingraft hydroponic technique. The results of this research showed that tapioca liquid waste affects of the growth of Ipomoea reptans Poir. However, the growth of plants treated with tapioca liquid waste is no better than those given by AB-Mix that commercially used by farmers.
