Get PDFCicatih is one of sub watershed which categorized as a good condition. However, if the land use allocation planning is not correctly, it is likely causing watershed degradation. The aim of this study was to assess land use changes and its influence on water discharging in Cicatih sub watershed. Some data were collected and analyzed including: rainfall, discharge, volume of discharge, flow regime coefficient (KRA), annual flow coefficient (KAT), land use change, and watershed conditions. There is a significant land use change in Cicatih sub watershed during period of 2009-2014. There are several significant increasing land uses, ie: dryland farming (77.26%), settlements (51.39%), and plantation (49.75%). Several significant decreasing land uses during the period, ie: scrub (96.78%), mixed dryland farming (78.74%), and rice field (74.50%). Land use changes in Cicatih sub watershed have an influence on the decreasing of watershed hydrological conditions. The value of KRA in the period 2009-2014 increase the category from medium (S) to very high (ST). In addition, the value of KAT also shows increase the category from medium (S) to high (T).

ESTIMASI POLA DISPERSI DEBU, SO2 DAN NOX DARI INDUSTRI SEMEN MENGGUNAKAN MODEL GAUSS YANG DIINTEGRASI DENGAN SCREEN3
Get PDFIndustrial 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
