Abstract

Problem encountered in the application of biopile technique for bioremediation of clay textured soils contaminated with crude oil is limited rate of air flow through the soil.  It is a challenge to solve the problem by adding the soil with sand. The addition of sand is also indispensable for the well growth and activity of bacteria in the bioremediation process. This study aims to evaluate the addition of sand on bioremediation of a clay textured soil contaminated with crude oil using biopile technique at pilot scale of 2 tons capacity. The results showed a decline of 76% soil TPH concentration, from 4.22% to 1.00%, within 63 days. Total population of bacteria during the bioremediation process ranged from 1.00 x106 to 1.43 x 1011 CFUs.g-1 soil. At the end of the experiment, a loss in the types and content of some easily degrading  hydrocarbon substances was observed.

Abstract

Industrial activities are sources of air pollution. Pollutants dispersion in air influenced by meteorological condition, such as wind speed, wind direction, air temperarture, air turbulence and atmospheric stability. Air quality monitoring is important in controling the worst condition of pollutants concentration. Air quality monitoring is not easy to do, because it is time consuming, costly and need technology, so that air quality model is developed as an alternative air quality monitoring. This research used gaussian model, a model for predicting pollutant concentrations in downwind area. This model is applied in cement industry, focusing on major pollutants of the cement industry. Sources of pollutants consist of dust, SO2 and NOx. The modeling results showed maximum ground level concentration of dust, SO2 and NOx occur at night (7-10 PM). The maximum ground level concentration of dust, SO2 and NOx at night respectively were 13.16 μg / Nm3, 32.69 μg / Nm3, 100.21 μg / Nm3 (N1 stack) and 14.65 μg / Nm3, 36.65 μg / Nm3, 128.10 μg / Nm3 (N2 stack) based from downwind scenarios at night when atmospheric condition was stable. The distance where the maximum ground level concentration occured has a strong correlation with wind speed (-0.82 ≤ r ≤ -1). Based on gaussian model output, air quality monitoring should be executed at night time (stable atmospheric condition) and located at ground level where maximum concentration occured. Increasing 50m of stack can decrease 57% pollutant concentrations in stable condition.

Abstract

Cement production was a process that requires huge thermal energy and produces high greenhouse gas emissions. Co-processing or utilising alternative materials and alternative fuels for the combustion process in kiln was a solution to meet energy needs and reduce greenhouse gas emissions in the cement industry. This study aimed to analyze input, output, environmental impacts of cement production and calculate CO2-eq reduction from the system used alternative fuels on co-processing. The method used to determine differences and calculate CO2-eq reduction due to co-processing was life cycle assessment (LCA) and system approach. Based on the results of the LCA, the case 1 that used 100% coal energy required 3.50 GJ/ton-cement, 126 kWh/ton-cement, 2.19 L-diesel-oil/ton of cement and emited 0.84 ton-CO2-eq/ton-cement. Case 2 that had been substituted alternative fuels (saw dust) required 3.03 GJ per ton of cement, 118 kWh per ton of cement, 1.44 L diesel oil per ton of cement and emited 0.92 ton-CO2-eq per ton of cement. The results of global warming impact of  case 2 was higher than case 1. The assumption of  climate neutral made reduction global warming impact of case 2 by 14.65% and decrease CO2 emissions annually in plant by 71,601 tons CO2/year.  This result show that utilization of saw dust as biomass of climate neutral can be applied as an input for overall company specific emissions calculation to meet government regulation.

Abstract

Indonesia as one of the developing countries has a high dependence on petroleum fuels derived from petroleum refinery as the main energy source. the use of foil in Indonesia is dominated to meet the needs of transportation vehicles. Fuel oil as a source of energy into the spotlight in the world lately because of the impact of environmental degradation that arise from the utilization. The industrial activity of fuel oil production in refineries is inseparable from the environmental impacts. The oil processing process at the refinery is the second highest emission contributor after the use of fuel oil itself during its product life cycle. In this research LCA analysis is conducted for the production of gasoline (bensin) and gasoil (diesel) vehicle fuels during processing at the refinery to compare the environmental impact of each type of fuel. From the result of LCA analysis, it is known that from two types of vehicle fuel, to produce 1 kilo litter of gasoline (bensin) type more energy and produce higher emission compared to diesel type gas (gasoil) fuel production. The gasoline fuel produced in the platformer unit is the product that has the highest emission contribution in its production process with greenhouse gas emissions of 1 Ton CO-2eq and the acid gas emissions of 0.001 Ton SO-2eq per 1 kilo litter of the resulting product.

Abstract

Nitrogen oksida (N2O) adalah gas rumah kaca yang berumur panjang dan memiliki potensi pemanasan 300 kali lebih tinggi dari CO2. Pelestarian hutan rawa gambut dapat mempertahankan sifat fisik dan kimia tanah pada kondisi alaminya, sehingga emisi N2O terjadi secara alami. Dalam upaya mengkuantifikasi emisi N2O dari ekosistem lahan gambut, ketersediaan data sangat dibutuhkan. Tujuan penelitian ini adalah untuk mengukur emisi N2O dari hutan konservasi, dan untuk memahami faktor-faktor utama yang mengendalikannya. Penelitian ini dilakukan dari bulan Januari sampai Desember 2020 di Semenanjung Kampar, Kabupaten Pelalawan, Provinsi Riau. Hasil penelitian menunjukkan emisi N2O pada hutan konservasi lahan gambut sebesar 0.23 ± 0.19 kg-N/ha/tahun. Perubahan subtansial pada tinggi muka air tanah, suhu tanah, kelembapan tanah, ruang pori terisi air, NH4-N and NO3-N secara signifikan mempengaruhi pertukaran gas N2O antara lahan gambut dan atmosfer.
