Abstract

Chitosan is one of the solutions in reducing heavy metal contamination inelectroplating industrial wastewater. Bionanomaterial chitosan has better ability because it has a specific surface area and nano-scale particle size. This research uses bionanomaterial chitosan to remove Ni from electroplating wastewater. This study aims to determine the effect of bionanomaterial chitosan concentration andstirring time in removing Ni in electroplating wastewater with variation ofconcentrations of 4000; 8000; 12000; and 16000 mg/L and stirring times of 30, 60 and 90 minutes using jar test. The initial concentration of Ni in electroplating wastewater was 2,025 mg/L. After the adsorption process, the highest efficiency value for Ni was 98,667 % at bionanomateial chitosan concentration of 8000 mg/Land a stirring time of 30 minutes.Keywords: Bionanomaterial Chitosan, Adsorption, Ni, Electroplating Waste Water.

Abstract

Characteristic of newspaper printing industry waste water has never been tested before, because there is still no waste water monitoring in an integerated way. This research utilizing clay to reduce heavy metal content of Cr contained in the waste water of newspaper printing industry. Preliminary analysis for Cr in waste water showed concentrations of these parameters exceed waste water quality standards of PERMENLH/5/2014. This study uses an ion exchange column with 5 cm diameter and 80 cm of height. The medium used is liquid waste newspaper printing and activated clay with a solution of H2SO4 2 M. The variation used is the calcination temperature is 200, 300, 400, and 500◦C and flow rate used is 2,7; 4; dan 5,3 ml/dt. The initial concentration Cr6+ ion is 0.838 mg/L. After processing the decline occurred in the ion concentration Cr6+ in every variation that is 0.334 to 0.582 mg/L. These results indicate that ion exchange method using activated clays are capable of removing concentration Cr6+ ion on wastewater printing. Overall, the variety used in this study to give effect to decreased levels of chromium and Lead in wastewater printing, also evidenced in Cr6+ ion removal efficiency ranged between 60.2% - 30.6%. KTK value of the clay is greater than the value of KA clay. Proving that the clays have a greater ability as compared to the ion exchange resin as an adsorbent.  Keywords: printing waste water, ion exchange, activated clay, temperature calcination and flow rate, KTK and KA.

Abstract

Electroplating liquid wastewater is liquid wastewater that comes from the process of coating a metal with other metals with the help of an electric current. This research conducts processing of electroplating liquid wastewater using a combination of treatment processes by biosorption using microalgae Chlorella sp. immobilization in an airlift bioreactor and further processing by coagulation and flocculation in a coagulation and flocculation reactor using Poly Aluminum Chloride (PAC) coagulants. The purpose of this study was to determine the removal efficiency, initial concentration and optimum contact time and functional groups in microalgae Chlorella sp. The variation of treatment in this study is the initial concentration of wastewater of 25, 50, 75, 100% with variations in contact time for 1, 2, 3 and 4 days in the biosorption process and the addition of a coagulant dose of 600 mg / L in the flocculation coagulation process. The results showed that the biosorption process obtained the best variation in the concentration of 75% wastewater in 4 days contact time. The combination of biosorption, coagulation and flocculation processing can set aside the Cr (VI) content of 93.03% and Cr (III) of 69.8%. Keywords: Electroplating Liquid Wastewater, Chlorella sp., Chrom, Wastewater Concentration, Contact Time.

Abstract

Aseptic packaging is one of the largest contributors of garbage where the production reaches 4 billion pieces per year. The handling of this garbage haven’t maximum yet, so it can be an opportunity to recycle the aluminum foil into alum. The aluminum foil on aseptic packaging contents 52% of aluminum, measured with Atomic Absorption Spectrophotometry (AAS). The product to make alum are 20%, 30% and 40% of KOH and the variation of 6M, 8M, and 10M H2SO4. The research show that the maximum produced of alum was mostly produced by using 40% of KOH and 6M of H2SO4 which produced 19,91 gr of alum from 3 gr of raw materials or equal to 72.69%. The characteristic of the potassium alum has content 4.59% of aluminum and 0% of insoluble substances.Keywords: Aluminum, Aseptic packaging, Potassium alum

Abstract

Transportation is the most influential source in increasing levels of carbon monoxide (CO) in the air. Pekanbaru is the capital of Riau province which is experiencing rapid economic development that is a cause of population growth and increasing the number of motorized vehicles. The purpose of this study is to measure CO concentrations from mobile sources then compare them with PP No. 41 of 1999, calculating CO concentrations with the Gaussian Line Source Model, and mapping the predicted distribution of CO emissions on Jalan Jendral Sudirman, Pekanbaru City. The method used is counting the number of motorized vehicles, measuring the concentration of CO in the field, and measuring wind speed in the field. Based on the results of research that has been done, it can be concluded that the highest wind speed is in front of Sudirman Square on Thursday at 3.0 m / s while the lowest wind speed is in front of the Ramayana at 0.5 m / s on Tuesday and Wednesday.Keywords: Wind Speed, Jalan Jendral Sudirman

Abstract

Organic matter contained in the hotel wastewater can be used as a nutrients of microalgae Chlorella sp. so its reduce COD. There are two treatment process happened in MBBR, suspended growth and attached growth by adding biocarriers in the reactor as a place for the propagation of microalgae. This research describes the study of effect of biocarrier (Kaldnes 1 (K1)) filling volume to decreasing COD in hotel wastewater. The study conducted in batches by varying of Kaldnes 1 (K1) filling volume with 4 different levels, that is 0% (without the addition of Kaldnes 1 (K1)), Kaldnes 1 (K1) filling volume as many as 10%, 20%, and 30% (wastewater volume). This process takes up to 5 days with solar irradiation in the MBBR. The result showed that 20% Kaldnes 1 (K1) filling volume happened in days-5 was able to reduce COD with efficiency of COD is 81.82%.Keyword: Chlorella sp., MBBR, Hotel Wastewater, COD
