Abstract

An increase in population will have a major impact on the environment, such as an increase in the volume of waste. The second largest composition of waste after food waste is plastic waste, which is a type of waste that is difficult to decompose. One of them is coffee packaging plastic waste. Recycling is a way that can be done to reduce coffee packaging plastic waste, namely by separating the plastic layer and the aluminum layer. The aluminum layer can be processed into alum. The purpose of this study is to separate the plastic layer and aluminum layer using the green solvent method using methanoic acid, the effect of variations in the concentration of KOH with a concentration of H2SO4 6M, and determining the optimum dose in reducing COD and BOD levels in wastewater tofu industry. The results showed that with the variation of the higher concentration of KOH, the yield of alum produced was also higher. Alum research results were compared with commercial alum. Comparison of these two types of alum shows that alum produced in this study resulted in higher COD and BOD removal efficiency than commercial alum, but with different coagulant doses.

Abstract

Ammonia is a wastewater pollutant that can cause oxygen depletion and eutrophication if not treated properly. The Photocatalyst using zeolite-TiO2 was effective method for degrading ammonia compounds in wastewater. This study aimed to analyze the characteristics of the zeolite-TiO2 composite and determine the effect of using the composite in reducing ammonia levels in wastewater. The research were conducted experimentally with a batch process on variations in pH and irradiation time. Data on the decrease in ammonia concentration with time was used to analyze the kinetics of the ammonia degradation reaction. The process of synthesizing zeolite from fly ash using the hydrothermal method. The synthesis of zeolite-TiO2 composites was carried out with a composition ratio of 1:2. Characterization of TiO2/zeolite composites was carried out using SEM-EDX and XRD methods. The results showed that fly ash-TiO2 zeolite composite has a granular morphology, and has an average diameter of 0.257 μm. X-ray diffraction pattern detected peaks in the form of zeolite X and TiO2. The highest ammonia removal efficiency was obtained at pH 11 with an irradiation time of 120 minutes, which was 91.60%. The process of removing ammonia by UV irradiation followed a second-order kinetic model with a k value of 0.1215 (mol.min)-1. The removal of ammonia in dark conditions followed a zero-order kinetic model with a k value of 0.0031 mol.min-1..
