Abstract

The City of Bukittinggi has developed into a center for tourism development in West Sumatra because of its natural and cultural characteristics, as well as its strategic location which has made it possible for the City of Bukittinggi. Land is the physical environment consisting of climate, relief, soil, water and vegetation as well as objects on it as long as there is an influence on land use, including the results of past and present human activities. The conversion of agricultural land to non-agricultural land use can theoretically be explained in the context of land economics which places land resources as a factor of production, where the point view that land is treated as a strategic commodity. The remote sensing data used is Landsat 8 OLI imagery for 2013, 2017 and 2022. Furthermore, classifying satellite imagery using the Supervised Classification method. Based on the results of processing satellite imagery in 2013, the area of paddy fields is 594.5 ha or 25.25% of the area of Bukittinggi City. The area of paddy fields in 2017 was 502.4 ha or 21.34% of the area of Bukittinggi City. Meanwhile, the area of paddy fields in 2022 is 427 ha or 18.14% of the area of Bukittinggi City. Based on the results of the change against paddy fields to built-up land in 2013-2017 paddy fields have decreased to become built-up areas of 118.3 ha. From 2017 to 2022 paddy fields have decreased to become built-up areas of 96.7 ha. And from 2013 to 2022 paddy fields have decreased to become built-up areas of 181.7 ha.

Abstract

Pariaman City has the potential for planning and damage caused by the renovation of the coastline. Shoreline change is one form of change in the coastal area that can occur continuously. The contributing factor to the occurrence of coastline changes can be caused by the presence of arareions and accretion. The aim of this research is to map the change in coastline and to know the pattern of aeration and accretion around Kota Pariaman Beach. This research uses data from Google Earth images over a time span from 2000-2020. Data for the year 2000 was used as a starting point for observing coastline changes (Baseline) and data for 2005-2020 as a Surveyorreline to calculate the rate and distance of Coastline Change using Digital Analysis Software. The results of this research are that from 2000-2020, the number of location points that experienced accretion was 125, while the number of points that experienced abrasion was 64. From 2000-2020, the area around Kota Pariaman Beach experienced a maximum accretion rate of 13,52 m/year in segment 118, while the maximum abrasion rate of -6.12 m/year occurred in segment 182. The maximum accretion distance is located in segment 118 of 265.46 m and the maximum aeration distance occurs in segment 182 of -120.13 m.
