Abstract

This research proposed a method to produce activated carbon from rice husk by carbonation process, physical activation and chemical activation using NaOH. The performance of activated carbon was tested by batch experiments in which the adsorption system contained 1 g of rice husk activated carbon in 100 mL of artificial wastewater with initial concentration of Cu(II) ion being 148.26 mg/L, initial pH 6, at 27 oC and 1 atm to determine the efficiency of reducing Cu(II) ion over the contact time and presence of stirring on chemical activation. The results showed that the efficiency of reducing Cu(II) ion by rice husk activated carbon increased exponentially with increasing contact time with a maximum value of 74.33% at 90 minutes of contact time. The results also showed that stirring on chemical activation increased the efficiency of Cu(II) ion reduction by 14.94%. Adsorption kinetics studies showed that Cu(II) ion reduction followed the pseudo-second order adsorption equation with the adsorption capacity of 10.18 mg/g and  adsorption rate constant of 0.0013 g/mg.min for rice husk activated carbon without stirring in the chemical activation. Stirring in the chemical activation.increased the capacity and rate of adsorption constant to 12.07 mg/g and 0.0052 g/mg.min, respectively.

Abstract

The batik home industry of Kampung Laweyan, Surakarta City did not make efforts to prevent environmental pollution from the wastewater produced. Waste water is discharged into the Jenes river, so that the river becomes polluted and contributes to the pollution of the Bengawan Solo River Basin. The study was conducted at the Environmental Laboratory, Environmental Engineering Study Program, Faculty of Engineering, Surakarta Christian University by conducting the coagulation process of flocculation with the jart test. This study uses variations and dosages of the type of FeSO4 and PAC coagulants with levels of 5% each for 100 ml / sec waste discharge. The results of the research are that before the waste is processed by the coagulation process, the value of BOD = 660.28 mg / l and COD = 1600. After the coagulation process, the efficiency of each type of coagulant is with FeSO4, BOD = 85.63% and COD = 82.67 %. With PAC coagulant, BOD = 90.21%, COD = 88.97%. This shows that the ability of PAC to reduce pollutant parameters is greater than ferrous sulfate.

Abstract

Laut Tawar Lake is located in Aceh Tengah District is the largest lake in Aceh Province. The lake, located at an altitude of 1230 meters above sea level, produces about 13 species of freshwater fish. Fish depik (Rasbora tawarensis), eyas (Rasbora sp.), and relo (Rasbora sp.) are endemic species of Laut Tawar Lake. This study aims to estimate the potential of fish production based on the value of morphoedaphic index. The observation was conducted for one year, from October 2016 until September 2017. The measurement of electric conductivity value of lake waters was conducted on 7 (seven) stations selected purposively in the lake area about 5870 hectares. The results showed that morphoedaphic index value of Laut Tawar Lake ranged from 5.10 to 7.84 with an average of 6.14. Potential of fish production in the lake is 33.47 kg/ha/yr with total potential of fish production of 196.49 ton/yr. The value shows a decrease of 10.93 kg/ha/yr over a period of 22 years. This decrease is caused by changes in morphometry parameters and water quality of Laut Tawar Lake.

Abstract

Organic substances in peat water cause smell, have a brown color and taste, in addition to that it can interfere the processing process by forming carcinogenic trihalomethane which is produced from the reaction between organic compounds and chlorine. Peat water used in this study came from the village of Tuah Indrapura, Siak Regency with a concentration of organic matter of 95.2 mg/L. Based on Permenkes No. 492 of 2010 the concentration of organic substances exceeds the quality standard, so it needs to be treated before being used as a source of clean water. Therefore, in this study, uses the coagulation method of flocculation by utilizing natural coagulants, namely tamarind seeds (Tamarindus Indica). The study was conducted using variations in the size of biokoagulan by 200 mesh, 230 mesh, and 270 mesh with a dose variation of 1 gr, 2 gr, 3 gr, 4 gr dan 5 gr. The result showed that using 270 mesh biokoagulan particle size as much as 2 grams can set aside organic matter by 64%. This allowance is not large enough because tannins only form aggregates with organic substances in the form of proteins and alkaloids.

Abstract

Biological-aerobic process is a technology that is often chosen to treat wastewater in industrial areas, especially industries related to food industries. Compared to chemical treatment and advanced treatment, biological treatment is relatively more efficient in the costs required. However, in conventional biological treatment the amount of energy consumption in the process is a major cost component that it becomes one of the challenges in implementing this technology. This paper contains a review of the implementation of the Food Chain Reactor (FCR) technology in treating industrial area wastewater, focusing on an overview of energy consumption compared to conventional biological-aerobic treatment of oxidation ditch (OD). FCR is a wastewater treatment plant (IPAL) that combines Integrated Fixed Film Activated Sludge (IFAS) technology and technology that resembles Constructed Wetland, thus enabling the simultaneous physical, biological and biochemical treatment processes within the reactor. In this case study, the implementation succeeded in showing a reduction in energy consumption by 46.4% while maintaining an efficiency decrease in BOD by 83% and efficiency in decreasing ammonia by 82%. As with the OD process, in this FCR study showed that the denitrification process has not been successful.
