Abstract

This study was conducted to clarify the ability of denitrifying bacterial group utilized nitrogen (N) due to decompose N in thiocyanate structure.Thiocyanate is a chemical that has likely pollutant to the environment, produced by some industrial activities. Denitrifying bacterial group obtained from bulk of sluge samples collected from the gold tailing, and some soil samples collected suround the gold mining site. The samples then were taken to the Microbiology Laboratory, Research Center for Biology, to investigate. Samples were initially acclimatized by potassium nitrate (KNO3), acetonitrile, and liquid waste or sludge. The result showed that denitrifying bacteria in the samples utilize 60 to 90% NO3-N (nitrate) in 42 days incubation. Isolation process were then conducted in each samples, and four denitrification bacterial, named as AN, Ea, L7T5, and PETI-7 isolates were attained. The isolates formerly cultured in a denitrifying bacterial medium containing KSCN (Potassium Thiocyanate), amended with glucose and sodium acetate for carbon source. Those four isolates performed satisfactory in aerobic and anaerobic cultures medium to denitrifying process, and utilize glucose and sodium acetate as co-carbon source, but all bacterial isolates were unable to use thiocyanate as the single carbon source. Thiocyanate degradation performed by the isolates through a simultaneous conversion along with denitrification process. This phenomenon turn to open the opportunity on role of application denitrifying bacteria become bioresources material in efforts to decompost thiocyanate.

Abstract

The remaining reagent from the sample analysis process become a significant source of hazardous waste of laboratory tasting activities. Methylene blue, phenol and oil are pollutants common in the remaining reagent waste. The electrocatalytic reactor is effective oxidation units for these organic pollutants. The reactor was made for a 50 L capacity with cylindrical metal oxide as the anode. The three anode which 6 cm in diameter and 50 cm in length were paired stainless cathode with the distance of 2.5 cm. The reactor was also equipped with a stirrer that is connected to the motor so that the mass transfer and oxidizing agents is more effective. The reactor application was carried out by feeding the remaining reagent waste into the electrocatalytic unit and giving DC potential 5 Volt. Each COD content for reagent waste of detergent: 2864 mg/L, phenol: 838 mg/L and oil: 708 mg/L. The reactor has reduced COD to 2157 mg/L (detergent), 399 mg/L (phenol) and 506 mg/L (oil) for 120 minutes. The high COD content in residual is caused by solvent (chloroform or hexane) that used at extraction step in determining the process of a sample. This compound is tough to oxidize into CO2 by OH radical or hypochlorite acid formed at the anode during the electrolysis process

Abstract

The present study seeks to examine nitrogen biotransformation of agricultural wastewater carried out by nitrosomonas and nitrobacter into Ammonia (N-NH3), Nitrite (N-NO2), and Nitrate (N-NO3) in Keduang watershed. Natural capability of the bacteria is necessary to find out to monitor assimilative capacity of the waterbody towards pollutants. Grab sampling technique was applied in agricultural land and Keduang watershed in reference to Indonesian National Standard (SNI) 6989.59:2008. Meanwhile, analysis of N-NO2 was based on Indonesian National Standard (SNI) 06-6989.09-2004, N-NO3 on SNI 6989.79-2011, and N-NH3 on SNI 06-6989.30-2005. The nitrosomonas and nitrobacter were isolated and identified on NA medium considering methods of Capuccino and Sherman (2005). Afterwards, characterization of colony morphology variants was determined, and both gram stain and biochemical test were conducted. A number of 48.8 nitrosomonas colonies/100 mL were identified in samples of agricultural wastewater, which enable to transform Ammonia (N-NH3) of 0.1390 mg/L into Nitrite (N-NO2) of 0.0632 mg/L. Meanwhile, a number of 330 nitrobacter colonies/ 100 mL are capable of transforming Nitrite (N-NO2) into Nitrate (N-NO3) of 0.2168 mg/L. In conclusion, there is a positive relationship between nitrosomonas in transforming Ammonia into Nitrite and nitrobacter in converting Nitrite into Nitrate. Nitrogen pollutants of the agricultural wastewater in Keduang watershed are able to be reduced by both nitrosomonas and nitrobacter.

Abstract

This study investigated several parameters for cell-wall disruption from microalgae Chlorella vulgaris during catalytic ozonation over microporous carbon-supported titanium oxide, including flow ozone, catalytic time, and reactor capacity. At the same time, the cell-wall disruption yield and an active compound yield such as chlorophyll and carotenoid were evaluated for each pretreatment. The required delivered flow ozone to achieve 76,47% cell-wall disruption of Chlorella vulgaris was 1 minute at 4 LPM, which produced chlorophyll 56,75% and carotenoid 89,09%. Carbon-supported titanium oxide reduces the required O3 dose and catalytic time for cell-wall disruption; however, it limited chlorophyll yield did not exceed 75,67%. Pretreatment with 1 minute at 1 LPM in 2 liters produced carotenoid yield by approximately 98,18%, though it reduced chlorophyll to 59,45%.

Abstract

Biomass waste in the form of fiber dregs contains many components of lignocellulose and hemicellulose. Lignocellulose can be used to produce ethanol through enzymatic biotechnology processes. Sago palm fiber industry is one potential industry producing biomass waste in the form of solid waste of fiber dregs (about 30% from the weight of processed raw materials). Solid fiber waste contains crude fiber and lignocellulose compound consists of cellulose (35-50%), hemicellulose ( 20-35%) and lignin (12-20%). This study aimed to utilize solid waste of sago palm fiber as a raw material of bioethanol production through enzymatic biotechnology processes of delignification, saccharification and fermentation which was then purified by distillation process to get ethanol. Delignification, saccharification, and fermentation stages are conducted using Phanerochaete chrysosporus Mushroom, Trichoderma viride fungus, and saccharomyces cerevisiae, respectively and then purified by distillation process (one level) to produce ethanol. The process of saccharification and fermentation process were done in an integrated manner (addition of Trichoderma viride and yeast saccharomyces cereviceae fungi done simultaneously). The weight of raw materials of solid waste fiber treated was about 6 kgs. Alcohol content obtained was about ± 4% (distillation). No water, air, and soil pollution inflicted, more added value, and sustainable were the main benefits of biotech process or bioprocess.

Abstract

This research aimed to investigate the influence of operational condition on the performance of halotolerant enriched - activated sludge system for treating high organic wastewater with medium salinity from roasted peanut industry. Roasted peanut wastewater with VLR ranged from 0.268 to 4.7 kg COD/m3.day and Chloride concentration ranged between 1582 - 4392 mg/L was treated continuously for almost 77 days. Two identical reactor with Volume 25 L, namely R1 a conventional Activated Sludge (AS) System and R2, a halotolerant enriched-AS. Both reactors were running with operational condition: HRT (9 h to 46 h) and MLSS (1000-6000 mg/L). Compared to conventional AS system, Halotolerant enriched-Activated sludge system could remove average of 86.7% COD, compared with conventional AS which was 85.7%. Average COD effluent of Halotolerant Enriched-Activated Sludge was also considerably lower, which was 127 mg/L, than conventional AS which was 150 mg/L. Halotolerant enriched-activated sludge also produced less sludge, giving a high F/M ratio (4.9) compared with conventional AS (3.5). In order to make effluent fulfilled stream standard regulation (at central java region COD was<150 mg/L), the favorable operational condition for both reactors would be at VLR 0.268 to 2.03 kg COD, HRT was 25 hours HRT, with MLSS was 2584 – 3956 mg/L and maximum chloride concentration 1920 mg/L.
