Abstract

In the process of melting steel industry specifically that using fuels MFO (Marine Fuel Oil) may cause air pollution, which is air contamination by the gases from the combustion (furnace metals) such as SO2. Pollutants pollutants released from the stack of PT. General Steel core Yaja Semarang to The air would cause pollution and causing the changes the concentration of SO2 in ambient air in the surrounding areas. The concentration of gas pollutant in the air other than influenced by the the amount of sources of pollution, meteorological parameters also influence the the concentration of gas pollutant in the air so that the environmental conditions can not be ignored. Wind speed, air temperature and humidity are part of the meteorological parameters that can influence the the concentration of gas pollutant in the air.

Abstract

The air in large cities exposed to a variety of pollutants. Of some kind of pollutant components, then the most influential in air pollution are the components of CO, NO, SO, HC and particles. Car is one of the sources of pollution in the air, the increasing number of cars that use the fuel, the emissions generated as hydrocarbons and carbon dioxide will increase. To ensure that the research done on the effect of distance and topography streets where automobiles to the concentration of HC and CO2 emissions.The method is carried out with the direct method of research in which direct conduct emissions testing on the sample car. Where the sample cars often pass through the area. And also conducted interviews directly to the owner of the car. From the analysis it can be seen the effect of the mileage and condition of the vehicle emission topography.The results showed that the farther the distance through which the vehicle is, the higher the HC and CO2emissions produced. But this has no effect on HC emissions vehicles often pass through areas with extreme topography. HC emissions generated on vehicles passing through the area with extreme topography higher than the vehicles passing through the area flat topography. As for the CO2, resulting in higher CO2 when passing through the higher elevations.

Abstract

As another town in Indonesia, Purbalingga also use landfill as a place to dispose solid waste/ rubbish. The landfill that serving Purbalingga area is located in Desa Banjaran Kabupaten Purbalingga which has an area of 4,7 hectare.The landfill consist of two pile’s zone and at this time only one zone left that still can be operated. The main problem in Banjaran Landfill management is diminishing availability of area to dispose solid waste and there is not available an alternative area that can be used for landfill location which makes Purbalingga threatened do not have an area to dispose their solid waste/rubbish. Beside that, solid waste management in that landfill not meet the environmental quality standar and still operated with open dumping system. The aim of this study is to evaluate TPA Banjaran and provide some alternatives to optimize the TPA by changing the method of disposal to be Sanitary Landfill method, infrastructure improvements and additions that are not yet available and make TPA Banjaran can be used more effectively and more optimal. Based on the assessment of the feasibility using SK SNI T-11-1991-03, 1991 can be conclude that TPA Banjaran is decent with environmental control (value 513). In addition, this study found an alternative optimization of TPA Banjaran with site optimization and change the operational methods using the sanitary landfill method.

Abstract

The processing of fish, would produce fluid that comes from the process of cutting, washing and processing of products. Fisheries waste, especially wastewater, is usually discharged directly into the environment and caused environmental nuisance. Fishing industry wastewater contains a lot of protein and fat, resulting in nitrate and ammonia values were quite high, so it can be used as raw material for a complete organic fertilizer. In this study, the wastewater derived from cleaning fishes is used as the raw material for liquid fertilizer because its nutrient content is very potentially to be used as a liquid fertilizer. One way to make liquid fertilizer is through fermentation techniques. In this case, it used six (6) variations in the addition of coconut fiber to determine the effect of macro nutrients for making the best liquid fertilizer. The variations were: 0 ml, 100 ml, 200 ml, 300 ml, 400 ml, 500 ml and it was being fermented for 28 days. The amount of coconut fiber that produces the best liquid fertilizer is by adding 100 ml of it which resulting in nutrient macro content of C-organic, nitrogen, phosphorus and potassium, respectively 11.69%, 2.251%, 0.74% and 0.029% at 14th day and the content of macro nutrients on 28th day for C-organic, Nitrogen, Phosphorus and Potassium are respectively 11.28%, 2.366%, 0.77% and 0.041%.

Abstract

Electroplating industries produce wastewater containing heavy metals such as copper and chromium that can pollute the environment because they are toxic and harmful to human health despite a small quantity. However, they require a wastewater treatment that could decrease heavy metal waste. Electrocoagulation is the selected method because it has high ability to treat heavy metals wastewater and the equipment is simply enough. The experiments were conducted with artificial wastewater with varying concentrations of Cr 30, 40 and 50 mg/ l and Cu respectively 50, 100 and 200 mg/l. This study used an electrode type Aluminum (Al) that had distance 1.5 cm each electrode, 5 ampere current strength, sampling time every 30 minutes, time operation 360 minutes with an electrode washing every 120 minutes. From the experimental result had been obtained the best efficiency to reduce Cr and Cu occurred in minute 120 which up to 97 %. Aluminum electrode having saturation began at minute 270.
