Application of Mulch and Palm Oil Waste as Bioremediation Agents in Post Mining Land

Abstract

Post-tin mining land in Bangka Island can be utilized by application of mulch and nutrient from organic material to stimulate plant growth. The aims of this study is to know the effect of mulch and palm oil waste to stimulate growth of mustard. The research was conducted in Post-Tin Mining, Bangka, from December 2018 to May 2019. This study used Factorial Randomized Block Design with two factors. The first factor was application of mulch consisted of without (M0) and application of mulch (M1). The second factor was application of palm oil waste consisted of empty palm fruit bunch (T1), empty palm fruit bunch + cow manure + Effective Microorganism-4 (T2) and empty palm fruit bunch + palm bunch ash (T3). The result of variance analysis showed that mulch and palm oil waste gave significant effect on all parameter except ash content. Mulch gave the highest result than without mulch, and empty palm fruit bunch + cow manure + effective microorganism-4 gave the highest result than the other treatment. Interaction between mulch and empty palm fruit bunch + cow manure + effective microorganism-4 gave the best result and could be a profitable solution to stimulate the growth of mustard.
