This research aim to settled high concentrated surfactants using calcium hydroxide. Using a jar test, the concentration of surfactants were measured. The batch test was started using a low concentration of surfactants at low pH. The results showed that calcium hydroxide was able to remove 95.16 % of surfactants. Which proved good performance of the chemical agent. This indicated that the chemical can be used to treat detergent rich content water or other effluent rich in surfactant content.

Acetic cellulose membrane is made from acetic cellulose, formamide and acetone using variations of composition and condition. Flux and rejection value was influenced by the characteristic of the composition and thickness membrane, pressure and time of operation. The result showed that flux would decrease and the rejection would increase if the composition of the acetic cellulose too much, while the thickness didn’t influence rejection score, but decreased the flux. The optimum pressure of operation to obtain the hight flux and rejection on their process was 1,75 bar for membrane compotition 14,8% (w/w) of acetic cellulose and the thickness 0,083 mm for membrane with operation time 75 minute. The optimum result was flux permeate 432,92 L/m2 days and 93,09% rejection score.

Publisher : Department of Environmental Engineering-Faculty of Civil, Environmental and Geo Engineering. Institut Teknologi Sepuluh Nopember, Surabaya

Using a radial mixing anaerobic reactor a study was conducted to remove organics of septic tanks sludge of IPLT Sukolilo. The results showed that the granular sludge quality of the biofilm of reactor was important for the organic removal. The granular sludge must exist and grow during high organic loading. The reactor was able to remove 72.62 % and 89.64 % of COD and SS respectively at a detention time of 28 hours. The same removal of detention time of 2.8 hours was 62.64 % and 76.42 %. The reactor was able to cope with the organic shocks. The start-up process for bacterial growth was an important step to achieve such removal.

From this research the merkuri in dam PT SIER equal to 0,967 + 0,138 µg/L ( p = 0,05), while cadmium concentration equal to 8,67 + 1,02 µg/L ( p = 0,05). Assess the bioakumulation merkuri and cadmium flesh of fish mujair ( Y; mg/kg wet heavy), times exposure ( X; day) certain, each according to equation of straight line YHg = 0,00355 X + 0,00703 and YCd = 0,0281 X + 0,0003 ( p = 0,05). At exposure more than 60 obstetrical day, cadmium in flesh of fish mujair have exceeded the sill of consumption boundary. While content merkuri in flesh of fish mujair reside in for sill of consumption boundary at exposure above 136 day.

A mathematical modelling was developed based on the theory of mass balance for the oil spills dispersion simulation. The model was tested in Dumai waters, PT. Caltex Pacific Indonesia, and eventually compared with reference model of Worldwide Oil Spill Modelling (WOSM). Dispersion model calculation was based on the spills of 1000 Barrels of Sumatran Light Oil. The simulation demonstrated that the concentration of oil dispersion with 10 m depth after 24 hours was 1.84 x 10-1 gr/m3, while the simulation result of WOSM was 8.84 x 103 gr/m3. The difference was due to the fact that the model was developed by a very simple assumption, that is only taking into account the advection process but not the transformation factor.

This research was intended to determine and analyze air pollution effect on plants. This research was carried out in two locations, in Kebun Bibit Bratang and on the street sides Baratajaya XVII Surabaya as control area. The observed plants were 14 species of dominant in Kebun Bibit Bratang. The highest average abnormality cell was Manilkara kauki (31,62%) and the lowest were Pterocarpus indiscus and Eucalyptus papuana (0%). The highest concentration of chlorophyll was Acalypha auriculliformis (1.576,32 ppm) and the lowest level was Eucalyptus papuana (413,66 ppm). Concentration pollutants in the air influenced on abnormality cell (derivation width cell, except palisade cell) and concentration of chlorophyll. The highest accumulated of Pb particles on the leaf was Lagerstromia speciosa (3,62 mg/m2) and the lowest was Pterocarpus indiscus (1,02 mg/m2).

UJI EKOTOKSISITAS MIKROBIAL UNTUK PENENTUAN BEBAN VOLUMETRIK SUATU PARAMETER MUTU DALAM PENGOLAHAN MIKROBIAL AIR DAN LIMBAH Sarwoko Mangkoediharjo

The weakness of conventional method is background the test of ecotoxicity mikrobial for processing mikrobial water and wastewater. From study we can hypothesis that there is correlation among volumetric mass and concentration level activity mikrobial equal to 50 % ( EC - 50 - TD). With the method test of ecotoxicity mikrobial yeast in a anaerobik condition during 2 hours, that possibility searched for the parameter quality of COD, NO-3, PO43-, Mn2+ and Fe2+. From the result give information of level of BV and EC - 50 - 2 hours and correlation between both of them; that is BV can be increasing as long as concentration input to the reactor mikrobial minimized or on the contrary.

Publisher : Department of Environmental Engineering-Faculty of Civil, Environmental and Geo Engineering. Institut Teknologi Sepuluh Nopember, Surabaya

This research measured the Specific Utilization Rate (SUR) of Reed and Cattail and compared the performance and growth between Cattail and Reed. The experiment was done in laboratory scale using batch condition with COD concentration (200 mg/L and 400 mg/L). The results showed that the utilization rate of Cattail was faster (11.51 mg/mg/day) than that of Reed on 200 mg/L of COD. The Reed utilization rate was 3.32 mg/mg/day on 400 mg/L COD. At COD level of 200 mg/L there was a significant difference between the utilization rate of Cattail and Reed, but not at 400 mg/L COD. It was found out that with the combination of plant and media, Cattail had better ability to reduce COD level from 200 mg/L and remaining 3.80 mg/L, while Reed performed the highest reduction of 400 mg/L COD and remaining 147.30 mg/L.

This research was aimed to determine the level of Surabaya river pollution according gills degradation of tawes (Puntius javanicus, BlKr.) and nila (Oreochromis niloticus) as well as melanophora pattern of fish scales. Weekly observations of some physicochemical parameter were pH, temperature, DO, COD, SS and biological parameter (respiration rate and melanophora pattern). The Prati Index the pollution level of Surabaya river in Bambe station was higher (polluted, class IV) than Cangkir station and Karangpilang station (good, class II). Results of gills observation showed that the pollution level in Bambe was higher (gills degradation level 4) than in Cangkir station and Karangpilang station (gills degradation level 3)

CAL3QHC (Caline 3 with Queueing Hot Spot Calculations) is a microcomputer-based model to predict carbon monoxide (CO) or other inert pollutant concentrations from motor vehicles at roadway intersections. The calibration had been conducted at Jl. Juanda-Diponegoro-Sulanjana intersection, which has high traffic volumes. The sampling was done for 6 times, each between 12-24 hours. The total number of sample used for calibration computations are 36 and randomly selected from each series of sampling. According to the research result shows a calibration curve of y = 1,2018x – 0,3477 where x is representing the result of model computation. Meanwhile the statistical analysis gives a correlation coefficient (r) of 0,74, which deals with the 1% level of significance degree (r) in 0,424.
