Abstract

AbstrakGreen open space (GOS) is a very important component in the arrangement of urban space,because the GOS has the function of ecological, aesthetic, social, cultural, and economic.Calculating of the GOS can easily be done in area that are enable for such purposes asurban forests, recreational areas of the city, as well as agricultural areas. However, for theland use consisting of non-GOS and GOS such as settlement, calculation of the GOS will bequite difficult. This research was conducted to measure the percentage of the GOS in settlementareas in the Denpasar city using remote sensing and geographic information systemtechnology. The results of this study showed that the percentage of the GOS in the settlementsarea of Denpasar ranged from 2.97% to 30.01%, with an average value of 14, 43%, and astandard deviation of 7.32% or 182.98 m2. The majority (50%) of the percentage of the GOSin the settlements area in the Denpasar city classified as moderate (10– 20%), 32% are low(<10%), and only 18% had a high percentage of the GOS (> 20%). Factors that influenceto the percentage of the GOS in the settlement area of Denpasar is the location of thesattements and the land area per housing unit.

Abstract

In this study, the use of SPI (Standardized Precipitation Index) combined with remote sensingdata is performed to map vulnerable drought areas in Bali-Nusa Tenggara regions. Analysisalso carried out to find the relationship between Vulnerable drought areas in Bali-NusaTenggara with El Niño phenomena. Bali-Nusa Tenggara islands are a chain of islands thathas a semi-arid climate type and resulted vulnerable to meteorological drought. Therefore,mapping of vulnerable drought areas in the region necessary to be carried out. The spatialpattern of the annual average value of SPI-6 in Bali Nusa Tenggara areas in 1998-2010indicates the spatial distribution follows the ENSO events. It also indicated in the spatialpattern relationship between ENSO and SPI in Bali-Nusa Tenggara islands. This studyindicates that remote sensing data such as TRMM 3B43 has the capability to be used as adata source to analyze the spatial patterns of vulnerable drought areas, particularly in theBali-Nusa Tenggara Islands. In addition, the TRMM data also possible to be used as a datasource to analyze the vulnerable drought areas in other parts of Indonesia.
