This study aimed to evaluate the suitability of space utilization conducted in the coastal area of Bungus bay. The research was conducted through field survey with a spatial approach using Geographic Information System (GIS) in order to know the suitability of area allocations which were served as a protected zone, utilization zone, and special zone. The results showed that zone II covers an area of 232,9 ha with a score of 48,4 and zone II covers an area of 136,2 ha with a score of 23 was not-suitable served as utilization zone, and zone III covers an area of 539,9 ha with a score of 61 was suitable served as utilization zone. Management alternative for not-suitable category in the protected zone at location 8 can be managed by the establishing of coast protection, establishing of stilt house, and the improvement of roads connected to the main road; On the utilization zone of location 11, location 12, location 18, and location 23 can be managed by relocating the settlement as far as >100 m from the coast, establishing of coast protection, establishing of stilt house, and improving roads connected to the main road; On the special zone of location 1 can be managed by relocating the distance limit of ship track and activity, making of settling ponds for waste discharging, and establishing stilt house; and on the special zone of location 25 can be managed by relocating the distance limit of ship track and activity, making of settling ponds for waste discharging, and dust suppression (wetting) during coal loading, and unloading.
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.
The purpose of this research is to determine the location of evacuation lines, TES or assembly points and shelters, and knowing the extent of the distribution of coastal tourism regions, as well as the distance of evacuation routes to TES or assembly points and shelters when tsunami occurs through the creation of a zoning model of coastal tourism-based disaster mitigation regions in Pariaman City. Methods in this research, i.e determining the location of TES or assembly points and shelters, and determine the capacity of TES or assembly points and shelters. Data processing and analysis for determining location, the capacity of TES or assembly points and shelters through the GIS approach. The results showed the tourism region of Gandoriah beach (7.8 Ha) an average tourist visit in 1 month in 2017 as many as 89.188 people/month with the number of TES or assembly points 2 and shelters 2, the tourism regions of Anas Malik and Cermin beach (16.11 Ha) an average tourist visit in 1 month in 2017 as many as 55.743 people/month with the number of shelter 1, the tourism region of Kata beach (19.68 Ha) an average tourist visit in 1 month in 2017 as many as 44.594 people/month the number of TES or assembly points 3 and does not have a shelter; and the tourism region of Naras beach (7.54 Ha) an average tourist visit in 1 month in 2017 as many as 33.445 people/month with the number of TES or assembly point 1 and shelter 1.
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.
This research aimed at designing the model of land cover changes in 1990 and 2014, and
