Abstract

In this study using a mixture of domestic wastewater. Parameters to be researched is the Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD) and nitrate-nitrogen (NO3-N). Alternative anaerobic treatment is to use UASB (upflow Anaerobic Sludge Blanket) . This study performed a variation of Hydraulic Loading Rate (HLR) and the influent concentration to obtain the optimum conditions on an UASB reactor laboratory scale for removal BOD5, COD and NO3-N in a mixture of domestic waste water (grey water and black water). Pollutant removal efficiency by varying the influent concentration and HLR for BOD5 was about 57% -76%, for COD was about 59% -69% and NO3-N was about 75% -98%. The results is the lower influent concentration will decrease removal efficiency that occurred on the parameters of BOD5, COD and NO3-N. The maximum removal efficiency on the parameters BOD5 and COD occurs when HLR low at 0.025 m3/m2/hour or 6.94 x 10-6 m / s. While the maximum removal efficiency of NO3-N occurred when HLR high 0.05 m3/m2/hour or 1.4 x10-5 m / s.  Removal for BOD5 optimum occurs at low concentrations are 419 mg / l with a variation HLR of 0.05 m3/m2/hour  or 1.4 x10-5 m / s,  for COD occurred at low concentrations are 878 mg / l with a variation HLR of 0.025 m3/m2/hour or 6.9 x10-6 m / s, and NO3-N concentration was occur in the 36 mg / l with a variation  HLR of 0.033 m3/m2/hour  or 9.2 x10-6 m / s. The results of treatment using UASB  still above the standards that should UASB be used as a secondary treatment  to obtain the effluent below quality standart.

Abstract

The production process activities by steel smelting factory and transportation activities can generate carbon monoxide (CO) gaseous that dangerous. PT. Inti General Yaja Steel Semarang located at the intersection of Jrakah is one of steel smelting industry which uses the MFO as fuel for their production activities. The volume of fuel MFO used for by PT. Inti General Yaja Steel Semarang production and the volume of vehicles passing through Jrakah intersection  are the source of carbon monoxide (CO) which the dispersion process is affected by humidity, temperature, wind direction and speed. This study aim is to determine the effect of the pollutant sources volume, humidity, temperature, wind direction and speed on the concentration of CO in the area of the factory PT. Inti General Yaja Steel  and at the Jrakah intersection, besides, to determine whether the concentration of CO is mutually influenced by conditions in these two places.The research was conducted at vehicle crowded hours, normal factory production hours and non- production factory hours . Based on these results, the concentration of CO in the factory area range in value from 2 to 2.75 ppm at both vehicle crowded hours, normal production at the factory hours and non- production factory hours. The concentration of CO at the Jrakah intersection in vehicle crowded hours (7:00 to 8:00) are in range of 1.75 ppm - 30.25 ppm, the concentration of CO at Jrakah intersection in normal production hours (15:00 p.m. to 16:00) were between 11.25 ppm - 22.25 ppm, and the concentration of CO at Jrakah intersection in non-production hours (19:00 to 20:00) were in the range 4.5 ppm - 22.25 ppm.The statistic results indicate that there are significant differences in the concentrations of CO results in the factory area and at the Jrakah intersection. CO concentration in factory area is not affected by the volume of fuel, humidity, temperature, wind speed and direction in its area, while the concentration of CO in Jrakah intersection are affected by the volume of vehicles passing through, humidity, temperature, wind speed and direction at the intersection itself. The concentration of CO in the area of the factory is not affected by the volume of vehicles passing through, humidity, temperature, wind speed and direction at the Jrakah intersection, and so the concentration of CO in the intersection Jrakah are not affected by the volume of fuel, humidity, temperature, wind speed and direction in the factory area.

Abstract

Sound in specific intensity which is caused by production engines in factories that operated for 24 hours all day are potentially causes one of  environment pollution impact, in this case is noise pollution. Main impact of noise are exposure objects surrounds the engines, that is Hearing Threshold Level (HTL) reduction of workers surrounds who are exposed by noise from that engines. This research is purpose to survey and analyze a noise intensity in Ring Frame area on Spinning 5 unit PT APAC INTI CORPORA, Bawen-Semarang and to analyze the diferrence of workers’re HTL before and after exposed by noise in that area. Before is when first time the workers work  in that area, and after is when this research did. Based on worker’re audiometric tests did in June 12th, 2013 for 15 workers in that area, shown that Hearing Threshold Level average of 4 workers suffered minor deaf right ear. And 3 workers suffered minor deaf left ear. The comparation result of hearing threshold level before and after exposed by noise in that area, can be inferred that occurs the increasing of Hearing Threshold Level (hearing reduction) of workers in that area. From comparative statistic analysis test Paired Sample T-Test, signification value (probability) is 0,000 < 0,05 that H0 denied (H1 accepted). So can be conclude that there is a strong relation between differences of Hearing Threshold Level before and after exposed by noise in that area.

Abstract

Along with the increasing number of urban population and urbanization, it will grow a lot of waste generated as well. According to the Public Works Department, the rate of domestic waste in Temanggung is 2.79 L/person/day, so that waste generation in Temanggung each day is 128m3/day. But the ministry was still 6.27%. To reduce the amount of waste generated in Temanggung had done some trash pemialahan in each house. Given the role of such a society, the waste produced by the settlement will be slightly reduced, where the waste could still be recycled back can still be useful. Based on the need to evaluate the condition of the existing waste management and to the development of waste management system in Temanggung.
