Abstract

Backscattering characteristics of land use has been analyzed using ALOS PALSAR data. The purpose of this research are mapping of land use by five categories such as forest, acacia, oil palm, open area and water, and to identify the changes of environmental. Analysis Pixel-by-pixel average of ALOS PALSAR level 1.5 backscattering used from five of category land use was to estimate the spectral characteristic of each object in difference HH and HV polarization. Ground truth data was taken from 169 locations which used for classification, 119 locations and 50 locations used for validation. Two different times of ALOS PALSAR level 1.0 2009 and 2010 data, was used for changes detection by multi temporal color composite combination. The accuracy result for classification map shows 62% of ground truth database, and multi temporal analysis showed the possibility of changes.

Abstract

Precipitation is one element of climate that mostly studied in Indonesia because it has a very high diversity both temporal (time) as well as spatial (place). The diurnal cycle is one of the important factors in the occurrence of rain in the islands of Indonesia that have an impact on regional rainfall patterns in Indonesia. The diurnal cycle of precipitation is an essential component of the tropical climate and one of the predominant components of atmospheric variations. The aims of this research were to determine and analyze the spatial patterns and the characteristics of rainfall diurnal cycle in Java Island and the surrounding areas (Java Island, Java Sea and Indian Ocean) using remote sensing data. In this study, data from Tropical Rainfall Measuring Mission satellite (TRMM) Precipitation Radar level 2A25 and wind data from National Centers for Environmental Prediction (NCEP) for 5 years period from 2007 to 2011 are used. The results of this research are the spatial patterns of daily rainfall in Java Island and the surrounding areas are different between land and sea. In the land, rain generally occur in the afternoon (12.00 to 18.00 LT), whereas in the ocean (the Java Sea and Indian Ocean) generally occur at midnight and noon (00.00 to 12.00 LT). The characteristics of rainfall diurnal cycle in Java Island and the surrounding areas are effected by land-sea physical properties, day-night cycle and by land-sea location.

Abstract

Climate change is a global phenomenon that affects all aspects of life. Climate change also affects marine life such as coral reefs. This study aims to determine the effect of climate stress on coral in Weh Island and Aceh Island-indonesia. This study combined ground check time series data with time series data of satellite oceans, data is grouped into two categories. They are biodiversity data and climate stress data. The biodiversity data obtained fish data and coral data from in-situ data since 2005 to 2011 and climate data stress data obtained from compilation of satellite ocean data since 1983 to 2011. Biodiversity data includes number species of fish and the genus of coral biodiversity and coral community susceptibility. Climate stress is grouped into three categories. They are radiation, stress reinforcing and reducing stress. Radiation stress factors consists temperature, UV light and doldrums. Stress-reinforcing factors consists sedimentation and eutrophication. Then stress-reducing factors consists temperature variability and tidal amplitude. Base on the research result shows that climate stress has impact on coral condition. Environmental pressure gives significant effect on biodiversity. The climate-change affects indirect impact on the fish and coral reef. Climate change influences the ocean condition. Some of the biodiversity cannot resist due to the ocean condition changes drastically.
