Abstract

Carbon emission that emited by electric plant in Jawa timur could be estimated. Estimation was done by emission factor calculation first. Emission factor was multipled with electric consumption value to got emmison carbon value. The method used ACM0002 that issued by CDM-PDD Version02 IPCC. Data supporting are NVC, SFC and CEF. The result could be found that coal and natural gas have emmision there are 1,00688434 Ton CO2/Mwh and 0,392860328 Ton CO2/Mwh. Keywords: carbon emission, emission factor, and electric plant

Abstract

PT. XYZ is one of industry that has a potential in green house gas emission that produce negative effect on human and environment. Therefore the study was aimed to investigate how much carbon value produced by PT. XYZ and how is the alternative solution to reduce carbon emission.The study method was based on secondary data such as; electricity, water and fuel consumption for one year taken from January until October 2009. The data was analyzed using CWFP, SEI, and ACM0002 methods for carbon emission value. The solution alternative for reducing carbon emission of PT. XYZ, was compared between electricity, natural gas and coal. It was concluded that, emission carbon value of PT. XYZ is 6.966,69 Tonnes CO2/years. Keywords: carbon emission, emission factor, and bottled water industry.

Abstract

Jeans dyeing is one of the large or small scale industries that produces liquid waste from the coloring process. Liquid waste that enters the water body will cause environmental pollution. It is necessary to study or test about the nature and characteristics of jeans dye wastewater. One of the tests that can be done is the toxicity test that refers to USEPA (2000) and OECD (2004) standards. Tests carried out by entering the concentration of certain wastewater in 5 (five) reactors with tilapia fish (Oreochromis niloticus) biota. Conducted preliminary research that is the 7 day acclimation process and 1 day range finding test. Running process carried out for 96 hours for fish 5 cm. Analysis was carried out every 24th, 48th, 72th and 96th hour for analysis of temperature, pH, DO, and mortality. Heavy metal (Cr) analysis is carried out in fish bodies and wastewater at each concentration. The initial characteristics of jeans stained liquid waste for pH: 7, temperature: 30, 7ºC, DO: 8.5 mg / l, TSS: 1040.0 mg / l; BOD: 137 mg / l; COD: 484.8 mg / l and Total chrome: 3.079 mg / l. The level of LC50 toxicity concentration in tilapia fish  fish 5 cm size of 12.59% results obtained from the calculation of probit with excel software. The content of chromtotal (Cr) contained in the test biota for 96 hours ranged from 1.03 l / kg to 1.93 l / kg.

Abstract

The final disposal of waste generation is a major environmental challenge in urban areas, especially in developing countries. Waste generation in developing countries will continue to grow as seen from the economic growth and changes in the consumptive patterns of the people, where current lifestyles and activities produce quantity of waste quickly. Waste is not only produced from households, but also from public facilities, such as school, institution, health, offices, markets, hotels, restaurants, and industries which later contribute to the generation of waste in the landfill. Waste management activities in landfills can produce various kinds of greenhouse gas emissions. This study aimed to determine the potential for greenhouse gas emissions from the rate of waste generation in Randegan TPA, Mojokerto City according to the parameters of the waste composition. Based on the research results, it was known that emissions generated from household waste amounted to 1.35 Gg CH4 and 3.72 Gg CO2, while non-domestic waste is 0.264 Gg CH4 and 0.728 Gg CO2.
