Abstract

Indonesian marine debris of aquatic waste in Jakarta is managed by the UPK of the Water Agency, one of which is the Pluit Employment. Several composting methods can be used and adapted to the available circumstances and needs. The composting process is carried out by utilizing the supply of oxygen, nutrients, water, and temperature control. This study aims to analyze the selection of alternative composting systems that can be carried out for planning the composting unit at Pluit Employment. Selection analysis was carried out using the Utility Theory and Compromise program methods. Alternative 1: This alternative uses a composting system using an open bin. Alternative 2 uses a simple windrow system with garbage piled up without heavy equipment during operation. Alternative 3 uses a composting system with a static pile system with a machine turning it over. In the composting method chosen, alternative 2. The distance between compost for workers' movement space, it can reach 1 m as in the TPS 3R Technical instructions, that because it does not use machines, the land used for machine movement is reduced. Limited land can be utilized for the amount of windrow so that the amount of processed waste can be more significant.

Abstract

The textile industry is one of the industries that discharge an enormous quantity of highly colored wastewater because of the large amount of water used in the process. Textile wastewater is the potential to polluting the environment due to the high color contained in it. One of the problems in processing textile wastewater with conventional treatment methods is the ineffectiveness of color removal. A post-treatment is needed for treated wastewater to remove the color. One of the methods is by using the ozonation method. In this preliminary study, the decolorization of artificial textile wastewater containing azo dye reactive-black 5 (RB5) from secondary treatment was investigated in a batch system. Artificial treated textile wastewater from secondary biological treatment was made using 5,26 mg/L azo dye RB5 in 16 L volume of the reactor. The preliminary batch study showed that the optimum color removal achieved in 24.66 mg/minute ozone dose in a batch system with 20,89 mg/minute ozone consumption. Within 5 minutes of ozonation, color removal achieved was 100%, and COD removal achieved was 75%.
