Abstract

Damage to coral reefs on Tegal Island has an impact on reducing coral reef habitats, so monitoring needs to be done. Monitoring is done by analyzing the extent and changes by utilizing remote sensing technology to map the existing conditions. The data used are Landsat imagery in 1998, 2008, 2015 and 2018. Digital image processing is done starting from image correction, lyzenga algorithm calculation, image interpretation and field validation, and accuracy testing of coral reef habitats using a confusion matrix. The results showed that there was a change in the area of coral reefs from 1998 to 2018. The coral reef class experienced a reduction of 11.22 ha. Coral classes that changed into sand classes were 9.13 ha (29.49%) and seagrasses were 4.38 ha (14.15%). The class of sand that turned into coral reefs was 2.08 ha (13.52%) and seagrass classes that turned into coral reefs were 0.21 ha (0.25%). The biggest change is the change in the coral reef to sand covering an area of 9.13 ha (29.49%), while the smallest change is the change in seagrass into a coral reef covering an area of 0.21 ha (0.25%). In the other classes, the biggest change in area was seagrass change into sand covering an area of 5.76 ha (6.96%), while the smallest change was the change in the sand to seagrass covering an area of 2.67 ha (17.35%).

Abstract

Pesawaran District, as a new district which was established in 2007, has experienced a rapid growth in population. As the population increases, housing and residential land needs will increase. Therefore, there should be a careful planning in determining the location of housing and settlement development in Pesawaran District. This study aims to: 1) Know the weight for each parameter used in determining the level of potential for a land for the development of housing and residential areas with method AHP 2) Know the potential level of land in Pesawaran District for the development of housing and settlements. The method used is AHP (Analytic Hierarchy Process), while the method by spatial analysis using GIS (Geographic Information System).The results of the study with AHP calculations show that the most dominant parameter is accessibility. The reason is, accessibility will affect the ease of transportation services and affordability of distance. The results of the analysis using GIS resulted in 5 potential locations for the development of residential and residential areas in Pesawaran District which are very potential (13456.50 ha), potential (47941.61 ha), quite potential (47362.11 ha), less extensively potential (16107.09 ha), and no potential (8251.13 ha).
