<![CDATA[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.ABSTRAK Pencemaran air limbah akan terus bertambah dengan meningkatnya jumlah penduduk dan aktifitas masyarakat.

<![CDATA[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]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[Abstract: Utilization of groundwater sources is still an alternative for people living in the coastal areas of Aceh Besar District. If the use of groundwater is carried out continuously, it will have a negative impact on the quality and quantity of groundwater. So the purpose of this study was to determine the distribution of groundwater salinity in the coastal areas of Aceh Besar District. The sample points were determined based on the random sampling method in grids. Sample testing for groundwater salinity was carried out directly in the field according to the planned location. The data obtained was inputted into Microsoft excel and mapping of groundwater salinity distribution using the Inverse Distance Weight (IDW) method with Argis software. A correlation test was performed with Pearson Product Moment. Based on the measurement results, 20 sample points of high salinity were measured. The distribution of salinity values also has a relationship with coastal distance, where the distribution of salinity in general, the farther the groundwater is from the coast, the lower the salinity value, and the closer the groundwater to the coast, the higher the salinity.Abstrak: Pemanfaatan sumber air tanah masih menjadi alternatif bagi masyarakat yang tinggal di wilayah pesisir Kabupaten Aceh Besar. Jika pemanfaatan air tanah dilakukan secara terus-menerus akan berdampak negatif secara kualitas dan kuantitas air tanah. Sehingga tujuan penelitian ini adalah untuk mengetahui sebaran salinitas air tanah di wilayah pesisir Kabupaten Aceh Besar. Titik sampel ditentukan berdasarkan metode random sampling in grids. Pengujian sampel untuk salinitas air tanah dilakukan langsung di lapangan sesuai dengan lokasi yang telah direncanakan. Data yang diperoleh diinput ke dalam Microsoft excel dan pemetaan distribusi salinitas air tanah menggunakan metode Inverse Distance Weight (IDW) dengan perangkat lunak Argis. Uji korelasi dilakukan dengan Pearson Product Moment. Berdasarkan hasil pengukuran, nilai salinitas yang tinggi terukur sebanyak 20 titik sampel. Nilai salinitas tinggi pada umumnya dipengaruhi oleh intrusi air asin terhadap air tawar. Faktor sebaran salinitas air tanah terjadi akibat intrusi, penggunaan lahan yang dekat dengan tambak dan muara sungai, faktor sebaran salinitas juga dipengaruhi oleh kepadatan penduduk. Sebaran nilai salinitas juga memiliki hubungan dengan jarak pantai, dimana sebaran salinitas secara umum, semakin jauh air tanah dengan jarak pantai maka nilai salinitasnya semakin rendah, dan semakin dekat air tanah dengan jarak pantai maka salinitasnya semakin tinggi.]]>
