Most ofMSW (40%) are transported to the Solid Waste Disposal Site (TPA) in urban area.The landfill site which is unmanaged will become a source of the GHGs emission,mainly the methane emission. Based on the Indonesian population, using FODIPCC Tier-2 method, CH4 generated from MSW sector (landfill only) in 2006 is109.96 Gg CH4 and will be increased up to 259 Gg in 2010, 504 Gg in 2015 and1,065 Gg in 2025. The increase number of this CH4 emission is caused by theincrease of population number that will increase the waste production and alsoincrease the volume waste that is collected in the disposal area. The future scenarioby referring to the national strategic plan which is developed by the Public WorkDepartment is that the waste should be reduced from the source, so the totalvolume will be reduced by 20% in 2010. In 2015, refers to the M...

Around 464 tpd (ton per day) are transported to Jabon Landfill, and about 298 tpd are treated at the Integrated Garbage Treatment Center (TPST), 3R Treatment Center, and the Bank of Garbage. Therefore, there are still 454 tpd of waste that has not yet been managed, potentially harming the environment. The still limited garbage service level to be transported to the landfill has made the community take the initiative to process the garbage with incinerators placed at the existing TPST. These incinerators can reduce the waste up to 25% to 30% by weight of the waste that enters the TPST. In this research, ten incinerators were studied in the TPST. From the sample conditions obtained, almost all incinerators were operated below the technical standards required for optimum operation and minimum environmental impact. The combustion temperature is generally below 800 °C, the gas residence time is less than 2 sec...

Secara global, pesawat udara menghasilkan 2% total produksi emisi karbon dioksida (CO2) per tahun, atau sebanyak 13 % dari emisi CO2 yang dihasilkan dari seluruh kendaraan dan diprediksi naik menjadi 3 % sampai tahun 2050.Studi ini bertujuan mengetahui jumlah emisi gas rumah kaca (GHG) dari sektor perhubungan udara dan prediksi pada masa mendatang. Dari hasil perhitungan dalam studi ini diperoleh total emisi GRK (CO2 dan CH4) sebesar 8.171,04 kTon CO2 eq terdiri atas emisi saat LTO 1.203,5 kTon CO2 eq (15 %) dan saat cruise sebesar 6.967,5 kTon CO2 eq (85 %) basis data 2012. Emisi GRK didominasi oleh gas CO2 (99,7%) sedangkan h...

In most landfill, leachate is consist of liquids that go into the landfill, which originated from outside the landfill, such as surface drainage, rain water, ground water, water from spring water and other liquids which produced from waste decomposition. The existence of pollutant material or minerals in water body that is originated from leachate will propose the growth of microorganisms, which are harmful for human health and reduce the aesthetic. Leachate handling could be done with several methods, such as: utilization of hydrolic characteristics by ground water adjustment, thus the leachate flows would not go into the direction of ground water. Another way of leachate handling are: landfill isolation, in order to prevent the inflow of external water and the outflow of leachate water; site selection of an area, which has a good capability of pollutant neutralization; leachate recirculation to be redirected to the solid waste pile; flowing the leachate to domestic waste treatment system and leachate processing with a certain system. Some processing techniques that are often to be used are: physical-chemical processing, such as coagulation-flocculation-settling; aerobic processing (activated sludge, stabilization pond or aeration pond); anaerobic processing, such as stabilization pond and utilization of sorption characteristics, such as active carbon. The aerobic stabilization pond system is suitable for Indonesian condition due to the availability of sunlight, simple, relatively cheap and their capability of BOD reduction above of 90% and COD reduction of above 80%.Kata Kunci : Leachate, TPA sampah, teknologi pengolahan.</jats:p>

Hierarchically, a suitable method for solving this condition is not to dispose the MSW into the landfill but to treat it in the thermal processing, such as incineration. The bonus of this incineration is the heat dissipation that can be utilized to generate electricity. Burning MSW through incinerator that converts into energy is often called a Waste to Energy (WtE) or PLTSa. Beside the benefit of the high temperature flue gas that can produce electricity, PLTSa also emits major pollutants in the flue gas such as particulates, SO2, NOx, CO, HCl, dioxins and furans. In order to meet the emission standards, the PLTSa design has to be equipped with APCD’s such as cyclone, semi-dry scrubber and bag filter. ID fan withdraws the flue gas into the chimney before discharging it into the ambient air through the top exit of chimney. The main parameters in the design of the ID fan and chimney...
