Abstract

The purpose of this study was to analyse the dynamics of carbon stocks changes from land cover into land settlement in the Padang City, West Sumatra. Method to formulate the change of land cover into land settlement in the Padang City is the analysis of Landsat Imagery 5+TM 1988, Landsat 7+ETM Image of 1998 and Landsat 7+ETM Image of 2008. Stratified Sampling Technique was Purpose Composite plot refers to the technique, but in this study carried out modification to the size of the plot which is then converted to the extend of each hectare of land cover. Estimating tree biomass using the equation according Kattering allometric, (2001). The result of the research conducted found that the dynamics of carbon stocks always decline from 1988, 1998 and 2008. This is caused by a reduction in forest area, shrubs, gardens, and fields are consistently due to the increased amount of land used for settlement.

Abstract

Seagrass ecosystems are exciting parts of the tropical coastal region that are potential for ecotourism activities. Marine ecotourism sector in the city of Padang has begun to develop within last few years. This development has not only positive impacts but also negative threats to the environment. Therefore, carefully select the most suitable areas for this purpose is important. This article aims to propose the potential areas for seagrass ecotourism in Padang city based on Geographic information system (GIS) analysis. We used spatial analysis to develop the seagrass ecotourism suitability index that is also potentially applicable to other areas. The results of the analysis show that area of the seagrass ecosystem in Nirwana beach (23.75 ha), Cindakir beach (2.56 ha), and Pasumpahan island (5.46 ha) with a total area of the seagrass ecosystem overall in Padang City (31.78 ha). These areas have been overgrown by Thalassia hemprichii with coverage >50 – 75 % in Nirwana beach, 25 – 50 % in Cindakir beach and Pasumpahan Island. The suitable areas for seagrass ecotourism were found on the beach of Nirwana (covers 84% as very suitable), Cindakir beach (covers 73 % as moderately suitable) and Pasumpahan island (covers 78 % as moderately suitable). We found that activities of local communities decreased the suitability of Cindakir beach and Pasumpahan island because these activities increase the abundance of mud in the substrate of waters.

Abstract

Coastal flood in Indonesia, namely as banjir rob, is a phenomenon that increases seawater to inundate around the tidal area. In Tanjungpinang, cases of coastal floods become a serious problem for people living in this area. This research aims to model the coastal flood inundation by modeling water inundation with a maximum level increase scenario. Its model was used to estimate coastal floods' impact on houses, buildings, and infrastructures with scenario 2 meters of sea-level rise.  On the other hand, the budget loss for restoration was estimated to study the effort of community adaptations with the ECLAC RAB method and observation to understand community adaptation. It was found that the spatial model succeeded in zoning inundation areas, which had a significant impact on houses, buildings, worship places, schools, and industrial at many 4112 units. From this case, the budget loss for the restoration of the physical environment was estimated at around 61994014.75 USD. In addition, the survey revealed the existing condition before and after the coastal flood. Several community efforts for adaptation were developing houses on stilt and hoarding the lowest land on-site location for build houses.

Abstract

ἀe purpose of this study was to analyze the trend of climate change through changes in the elements of Green House Gases (GHGs),   includes the trend of CO2, N2O, and CH4. ἀe change of the  extreme rainfall and temperature  indices due to land cover change into developed area in Padang. IdentiḀcation and analysis trends of climate change and extreme climatic events were analyzed by using RclimDex the Expert Team for Climate Change Detection and Indices (ETCCDMI) technique. Where as the analysis and interpretation of  land cover changes  into developed area used Landsat TM 5 and Landsat 1985 7 ETM +  of 2011 by ERDAS 9.2 GIS with the supervised classiḀcation method and GIS Matrix. ἀe results of the study provide informations of land cover changes into developed area at forest land  (11,758.9 ha), shrub (3,337.3 ha), rice Ḁelds (5,977.1 ha), and garden (5,872.4 ha). It has an implication on increasing of  the ele-ments of GHGs concentration such as CO2 (14,1 ppm), N2O (5,4 ppb) and CH4 (24,8 ppb). ἀis condition lead to an extreme temperature and presipitation indexs trends in Padang.

Abstract

This research aimed at designing the model of land cover changes in 1990 and 2014, and estimating carbon stock changes in each land cover in Leuser Ecosystem Area (LEA). The spatial model of land cover changes was analyzed by interpreting Landsat 5 TM imagery in 1990 and Landsat 7 ETM+ imagery in 2014 with ERDAS 9.1 and Land Change Modeller (LCM) in Idrisi TerrSet v.18. The analysis of land area changes (ha) in each land cover from 1990 to 2014 used ERDAS 9.1 with tools Interpreter (GIS Analysis-Matrix). Systematic survey method was employed in order to analyze carbon stocks. The sampling technique was stratified purposive composite sampling which used plot technique. The estimate of tree biomass used allometric equation. The estimate of carbon stocks in each land cover in 1990 was measured based on the total of carbon stocks in 2014 which was conversed with the areas of each land cover in 1990. Spatial model of land cover changes in LEA in 1990-2014 showed the changes of area in each land cover which caused the changes of carbon stocks in each land cover as well.

Abstract

The aims of this study are to 1) describe the forms of changes in socio-economic life after the earthquake disaster on September 30, 2009; and 2) Explaining the impact of change on the interaction of the society of Pariaman City. Data was collected using observation, interviews, and documentation. To test the validity of the data, the researcher triangulated the data. The research informants were the victims of the September 30, 2009 earthquake, society leaders, sub-districts, and city governments. The technique of selecting informants using snowball sampling. Data analysis of this research was carried out using an interactive model developed by Matthew Miles and Huberman (1992). The findings of this study indicate the changes in the socio-economic life of the society after the September 30, 2009 earthquake marked by the increasingly heterogeneous social life such as the formation of new groups in society, the diversity of livelihoods. The impact of the change causes society to become more individualistic, social relations are more tenuous and more selfish and the society is dependent on obtaining earthquake relief funds.

Abstract

The concept of integrated waterfront management is a development concept that involves all stakeholders such as government, private and public as well as stakeholders in the waterfront city area. So that waterfront management leads to a planned development approach in the coastal area. With the concept of integrated waterfront management, it is hoped that stakeholders in the waterfront city area can manage development that maintains a balance and can be tolerated by the community and the environment.
