Abstract

The textile industry is one of the industries that produces liquid waste in the form of dyes such as blue Bordeaux which can be treated biologically, physically or chemically. Biological waste treatment has the advantage since it is safe, environmentally friendly, does not require large costs, and does not cause additional waste pollution. Biological waste treatment can be carried out using white rot fungi (Omphalina sp and Pleurotus ostreatus) and ligninolytic-methylene-blue degrading bacteria as the decolorizing agents in doses of 15, 30, 45% (w/w). The decolorization test was carried out using two methods, namely the Rotary Biological Contactor (RBC) and Batch Biological Contactor (BBC). This study aimed to determine the optimum concentration of biological agent and to compare the best method among the two in terms of blue Bordeaux decolorization. A factorial Completely Randomized Design (CRD) was used and the data was analyzed using ANOVA (analysis of variance) with a 95% confidence level followed by Tukey’s Honest Significance Difference Test. The results showed that not only the type of agent but also decolorization method had a significant effect on the level of decolorization of the blue Bordeaux textile colour. The highest percentage reduction of blue Bordeaux was found in Omphalina sp. as biosorbent with a concentration of 30% using the RBC method for 24 hours. Keywords: dye decolorization, ligninolytic microorganism, Omphalina sp., Pleurotus ostreatus

Abstract

Oil Palm Empty Fruit Bunches (OPEFB) is one of the large solid wastes produced in oil palm industries. In this study, a technique of fast composting of oil palm EFB was carried out. This research aims to assess the effect of aeration on water content, the dynamics of temperature, fungal growth, and the carbon-nitrogen ratio of the EFB. Treatments tested in this study were three types of ligninolytic fungal isolates as decomposers (Omphalina sp, Pholyota sp, and Omphalina sp + Pholyota sp.) and two types of aeration, i.e., with or without aeration in the composting pile. The study was done for seven weeks on open land. The water content of composting piles on aeration treatments (48.7-53.7%) was slightly higher than treatments without aeration (37.2-45.56%). Based on the parameters of increasing temperature, the EFB decomposition process increased and reached a maximum in the second week and then decreased in the period incubation of 7 weeks. Giving aeration to the EFB pile inoculated with decomposer seems to produce slightly better mycelium growth by about 20% than those without aeration. In general, the values of the C/N ratio were lower in the aerated EFB piles compared to those without aeration. Management of aeration, such as controlling the period of aeration, is needed to maintain EFB moisture in the presence of aeration or add material that keeps the aeration will maintain the optimum water content in a pile. Keywords: decomposers, ligninolytic, Omphalina sp., Pholyota sp
