Abstract

Flooding has become a serious problem in Jakarta. During floods .of 2007, Kampung Melayu, East Jakarta was the worst hit.by the floods. Community have different perceptions on disaster and have different effort to overcome the hazards. Therefore, local government and relevant institution should investigate this situation and make this information a valuable input in developing and implementing response plans in flood mitigation. This research is to explore the vulnerability of floods based on local people's perception. There were 83 households interviewed using questionnaire. Certain elements at risk related with physical and socio:economic aspects were identified. Physical information concerned the building structure and building contents. Several socio-economic characteristics were used as key indicators to analyze the vulnerability of people. Generally, the result of this research shows that the ability of people to cope with the flooding i$ linked with the capacity of the people itself. The capability of people to deal withflooding was influenced by several indicators.based on their socio- . economic characteristics. For example, lower income people will experience more suffering than the wealthier, because they cannot afford the' costs of repair, reconstruction. Although the wealthier are likely to experience a higher degree of economic damage due to possessions of higher value. Base on the analysis, all coping strategies and flood measures are not enough to cope with flooding in the study area.

Abstract

Considering the abundance of potential pollutant sources along Bedog River, i.e. highly dense residential areas, agricultural lands, and industrial areas, this study aimed to quantitatively assess the Pollutant Load (PL) and Pollutant Carrying Capacity (PCC) of the river based on Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)parameters. The assessment employed a water quality modeling using Qual2Kw that provided not only the comprehensive values of PL and PCC but also the amount of PL that should be reduced to meet the PCC of every river segment. Water sampling and primary parameter measurement were conducted purposively in seven observation points, which included one point source and six non-point sources (river segments). River segments were determined according to the characteristics of land use and drainage system. Descriptive, graphic, and spatial analyses on water quality modeling show that the COD and BOD of Bedog River (2.24 km) indicates a small presence of PL compared to the river’s PCC. The PCC allows additional pollutant loads of 566.95 kg/day or 0.024 ton/hour BOD and 22,965.12 kg/day or 0.96 ton/hour COD. However, a high BOD in segments 3, 5, and 6 and a high COD in segment 5 imply the needs for PL reduction.
