Wastewater pollution will continue to grow as the population and community activities continue to increase. Various techniques have been applied for domestic waste treatment, but generally these processes require relatively high operation and maintenance costs. Down Flow Hanging Sponge (DHS) has been proposed as a solution to the problem of handling domestic waste for developing countries. DHS bioreactor is a biological waste treatment that does not require an aerator and is easy to operate. This study aims to evaluate DHS bioreactors that can be applied in Indonesia. DHS bioreactor is operated with 4 hours hydraulic retention time (HRT). The results showed that DHS bioreactor is able to reduce up to 34% Chemical Oxygen Demand (COD) total, 33% soluble Chemical Oxygen Demand (COD), 80% Biological Oxygen Demand (BOD) total, and 65% Ammonia.ABSTRAKÂ PencemaranÂ air limbah akan terus bertambah dengan meningkatnya jumlah penduduk dan aktifitas masyarakat.

Tofu is a very favorite food in Asian countries such Indonesia, and is gaining popularity among west countries as well, due to the associated health benefits and its acceptable price. Tofu which is produced by grinding of soy bean produces high of amount wastewater, and is considered as one of the most polluting food-industrial effluent due to its high values of organic pollutants. This paper analyzed some pollutants parameter discharged from tofu industries in Banda Aceh. The parameter of BOD, COD, MLSS, PO4-P NH3-N, Turbidity and pH were analyzed based on the standard method for the examination of water and wastewater, approved by the EPA. The COD and BOD of wastewater from tofu processing facilities in Banda Aceh is ranging from 5000-8500 and 3500-4500 mg/L, respectively. Site investigation showed that in Banda aceh city, the tofu waste has been disposed into the environment without any treatment, causing bad odours and pollution of the surface, ground water and river

The behavior of heavy metals eluted from the wall of Ni/Fe-based alloy reactors after high-temperature and high-pressure water reaction were studied at temperatures ranging from 250 to 400oC. For this purpose, water and cysteic acid were heated in two reactor materials which are SUS 316 and Inconel 625. Under the tested conditions, the erratic behaviors of soluble metals eluted from the wall of Ni/Fe-based alloy in high temperature water were observed. Results showed that metals could be eluted even at a short contact time. The presence of air also promotes elution at sub-critical conditions. At sub-critical conditions, a significant amount of Cr was extracted from SUS 316, while only traces of Ni, Fe, Mo and Mn were eluted. In contrast, Ni was removed in significant amounts compared to Cr when Inconel 625 was tested. It was observed that eluted metals tend to increased under acidic conditions and most of those metals were over the limit of WHO guideline for drinking water. The results are significant both on the viewpoint of environmental regulation on disposal of wastes containing heavy metals, toxicity of resulting product and catalytic effect on a particular reaction.

This research is a preliminary study of the utilization of chitosan modified with liquid smoke to produce edible coating material that can be used as a preservative of beef. Chitosan compounds obtained from shrimp shell waste, while liquid smoke produced from pyrolysis of palm shells at a temperature of 340oC. Edible coating solution with various concentrations was made by dissolving chitosan (1-1.5%) into 3% liquid smoke, which was then applied as a meat preservative. Meat samples that have been dipped edible coating for 15 minutes, then stored in the refrigerator and observed decreased endurance every 24 hours for 8 days. Analysis results of Gas Chromatography-Mass Spectrometry (GC-MS) showed that liquid smoke contains phenol and acetic acid compounds that have antimocrobial properties. Meat endurance test was done by analyzing the aroma, texture and color of meat. The results showed that the beef that has been coated liquid chitosan solution can last up to 7 days. Chitosan concentration affects the endurance of meat, the greater the chitosan concentration, the better the meat endurance. The optimum concentration was obtained at 1% of chitosan, the meat still has an acceptable aroma, texture and color for up to 6 days. This suggests that chitosan-liquid smoke can be used as an edible coating material.

The industrial liquid waste is very dangerous because it still contains elements of pollutants with a relatively large waste parameters. One way that can be used is by the method of adsorption or absorption. In this research the absorbent used is Natural Zeolite in nano meter scale. Zeolitewith nano meter size is obtained by smoothing using ball mill for 15 - 20 hours. Furthermore, nano zeoliteis activated physically and chemically. Nano zeolite will be characterized using X-ray Diffraction (XRD), Fourier Transform Infarared (FTIR), Scanning Electron Microscopy (SEM), and characterization of N adsorption desorption. Results of the study obtained the highest adsorption capacity and percent removal is performed by ziolites that are activated with nano-size ZnCl2 with a value of 440.5 mg/g for adsorption capacity and 65.9% for percent removal. In this study, the equation for calculating the zeolite performance in lowering the COD content in the effluent was used Langmuir’s isotherm equation. The determinant coefficient (R22) of the Langmuir isotherm equation for 35 μm zeolite and non-activated nano meter performance were 0.9974 and 0.9983, respectively. While unzaked zeolitefor size 35μm and nano meter are respectively equal to 0,9977 and 0,9197.

The possibility of organic and amino acid production from the treatment of sludge and fish waste using water at sub critical conditions was investigated. The results indicated that at sub-critical conditions, where the ion product of water went through a maximum, the formation of organic acids was favorable. The presence of oxidant favored formation of acetic and formic acid. Other organic acids of significant amount were propionic, succinic and lactic acids. Depending on the type of wastes, formation of other organic acids was also possible. Knowing the organic acids obtained by hydrolysis and oxidation in sub-critical water of various wastes are useful in designing of applicable waste treatment process, complete degradation of organic wastes into volatile carbon and water, and also on the viewpoint of resource recovery. The production of lactic acid was discussed as well. The results indicated that temperature of 573 K, with the absence of oxidant, yield of lactic acid from fish waste was higher than sewage sludge. The maximum yield of total amino acids (137 mg/g-dry fish) from waste fish entrails was obtained at subcritical condition (T = 523 K, P = 4 MPa) at reaction time of 60 min by using the batch reactor. The amino acids obtained in this study were mainly alanine and glycine.Keywords: organic acids, amino acids, sub-critical water, hydrothermal, resources recovery

The supercritical CO2 extraction of microbial quinones from activated sludge samples obtained from various activated sludge was investigated and compared to the conventional method using organic solvent extraction. The extraction was carried out in a supercritical fluid extraction (SFE) system in the temperature range of 25 to75 oC and the pressure up to 30 MPa. Different extraction conditions, such as the temperature, pressure, extraction time and modifier were employed to maximize the SFE efficiency. Significant amount of microbial quinones (ubiquinones and menaquinones) could be extracted rapidly with supercritical CO2. Results on the value of diversity and dissimilarity suggested that the SFE with supercritical CO2 extraction was a reliable technique for quinones extraction.
