Abstract

In flood-prone areas, coordination between parties in disaster risk reduction (DRR) activities is very important. This is because the consequences of disasters will directly affect the disruption of people's lives and livelihoods, and also hinder the process of sustainable development. The study aims to develop a public coordinating scheme for disaster risk reduction (DRR) activities based on public resources in Gorontalo Regency. Public resources from government agencies and society are available in Gorontalo Regency with their respective tasks at the stages before, during and after the disaster. Public coordination is expected to support the implementation of DRR-based sustainable development in Gorontalo Regency. The preparation of public coordination scheme begins with geospatial flood hazard assessment based on the characteristics of the Limboto Watershed using a Geographic Information System (GIS) tool. The result provides a basis for the implementation of public coordination arrangements for DRR. Gorontalo Regency is dominated by a coastal land parcel adjacent to Tomini Bay, stretching from lowland plains to hilly mountains. High rainfall, critical land use and settlements in the lowlands have caused the study area categorized into high- to very high-risk zones of flooding. To ensure sustainable development runs effectively, its implementation must be based on DRR policy with public coordination. Public coordination is carried out between government agencies and society, who cooperate in compliance with their respective roles and tasks at the stage before, during and after the disaster. The results show that the involvement of more sectoral parties is needed at the stage before and during the disaster. This indicates that public coordination before the disaster performs risk prevention and reduction activity that should be prioritized in the implementation of development before inhibiting its sustainability.

Abstract

Groundwater and surface water are important sources of clean water which require an effective management. The use of groundwater and spring as exemplified by Batu City case – as part of Brantas watershed upstream – serves as raw water as well as clean water source for Batu City and Malang City population. Contamination of surface water and groundwater affects clean water supply as indicated by increasing nitrate, TDS, and E. Coli concentration. The study aims to analyze the vulnerability level of groundwater contamination by using spatial multicriteria analysis with DRASTIC index. The DRASTIC index is measured from some parameters such as surface water depth to water table, net recharge, aquifer media, soil media, topography, impact of vadose zone, and hydraulic conductivity to evaluate groundwater vulnerability. The results show that Batu City performs low vulnerability (86.93%) and medium vulnerability (13.07%) levels. The dominant factors affecting the level of vulnerability are groundwater levels, slope, and geological conditions across regions. Even though the DRASTIC modelling cannot specify the contamination levels of the different sources, this method is useful to identifying high-level contaminated land uses, managing water resources, and conserving groundwater sources.

Abstract

Many small urban areas experience rapid population growth that create significant challenges in providing infrastructure and urban services. Especially in Java, Indonesia, many small urban centers are formed, grown and developed in the urbanization process of many kabupaten (non-urban districts), so made them have many urban areas in their territory. Using the case of Kabupaten Sleman in Yoogyakarta, this study is aimed to analyzes and to comprehend the growth and development of urban areas in kabupaten’s territory. The research employs a quantitative method that uses statistical data gathered from podes (villages monograph) data, monograph of the kecammatan or sub-districts, and monograph of the kabupaten or non-urban districts.The analysis observes the growth of urban areas in the kabupaten during 1990 to 2010, and the growth and development of the urban areas is observed in twoaspects, namely the observation to the expansion of the urban areas by using the development of their urban villages and the growth of their population. The research reveals that Kabupaten Sleman experiences rapid urban growth in its territory, which is also characterized by urban population explosion, especially after 2000. The growth of urban areas occurs in both internally as well as the expansion of the urban areas into surrounding (externally), which is also influenced by the expansion of the area of the capital of the kabupaten, as well as by the implications of its location adjacent to a big city, the Municiality of Yogyakarta.

Abstract

Denpasar City as the capital of Bali Province is attractive to regional development. The limited space of Denpasar City directs the development towards the periphery. The extension of physical urban form will be a significant factor of suburban developments. The study aims to examine the type of urban sprawl development in the Denpasar suburbs, and their relation to the existence of agriculture. The qualitative research method is used to analyze the type of urban sprawl with the following indicators of typical land uses covering rice fields, forest park, open land, and settlements. Remote sensing analysis of these four indicators applies GIS model drawn from three time-series data of 2005, 2010 and 2015. Spatial approaches are applied to examine the patterns and structures of urban sprawl types. The results find two main types of urban sprawl development in the city suburbs, that is, leapfrog type which is mostly scattered in the north, and the ribbon type mainly centered in the eastern part of Denpasar City. Both types of urban sprawl play a crucial role in decreasing the amount of agricultural land, especially rice fields, in the suburbs of Denpasar.

Abstract

The increasing population every year and the rapid economic development in Semarang City caused environmental problems related to the water resources used. One of the impacts of environmental problems is the lowering water quality of the Banjir Kanal Timur (BKT) Watershed. The study aims to identify the potential and conditions of the BKT watershed, and river segmentation as a basis for determining representative monitoring points that are used to determine the capacity that is adjusted to the description of river water segmentation class. The methods were descriptive and quantitative analysis approach based on the observation and measurement in the field campaign as well as the laboratory analysis. In addition, this research was also compiling the QUAL2E modeling to determine estimation of contamination load and capacity of contamination of Banjir Kanal Timur. The results conducted that the BKT has poor water quality based on the parameters of DO, BOD, and fecal coliform, while for the NO3 and NO2 parameters indicate good water quality. Segment that has load capacity of BOD contamination is segment 1. Segments that have load capacity of Nitrite (NO2) and Nitrate (NO3) contents are segment 1 to segment 4. The segment which has load capacity of contamination of fecal coliform is segment 2. Thus, Segment 1 can be classified into second class while segment 2 goes into third class. Furthermore, segment 3 and 4 are into fourth class respectively.
