Abstract

The coastline is the meeting area between land and sea. In this area, many are influenced by various natural factors and also human activities, where changes that occur such as climatological effects will have an impact on the existing coastline, as well as human activities in the coastal areas will have an impact on the morphological form of the coast including in it the coastline. This study intends to see which mathematical model is most suitable for describing the changes that have occurred and also to measure how much change occurs each year. The method used in this research is spatial analysis using a geographic information system which is used to analyse the Landsat 8 OLI satellite image of the coastline in Bangkalan Madura district, and to measure satellite imagery for a period of 5 years from 2016 to 2020. The results obtained from this study, the polynomial mathematical model is the most suitable model to describe the process of change, where this model provides maximum results with a significant correlation value of 0.8107 for degree 2 and 0.9323 for degree polynomial 3. From this study It can be concluded that Landsat 8 satellite imagery is suitable for data collection on shoreline changes because this satellite image has sufficient resolution to describe in detail the length of the coastline under study. Changes in the coastline that occur are not linear, but throughout the year there are fairly dynamic changes to the shoreline, both in terms of a shoreline retreat or an addition to the coastline.

Abstract

Indonesia is a country that has a high population density. The increasing population causes an increase in the demand for household needs. As time goes by, human needs are increasing day by day. Starting from primary needs to secondary needs. The city of Surabaya is the second largest metropolitan city after Jakarta with a population of around 2,874,314 people in 2020. With such a large number, of course, it has various kinds of demands to fulfill primary needs, Alfamart and Indomaret as the two largest retail companies in Indonesia are trying to be in the midst of Public. However, the uneven distribution of Alfamart and Indomaret locations causes the public to be often confused about their existence. To meet the need for information dissemination in that location, the system will be made based on mobile web so that the system can be accessed via a mobile smartphone device that is equipped with a GPS (Global Positioning System) so that it can find out the coordinates of the location of Alfamart and Indomaret, namely in the form of latitude and longitude data. This will make it easier for people who want to know the location and know the distance to the intended location and data by utilizing services from Open Camera and Google Maps.

Abstract

Gunung Anyar is one of the districts in the city of Surabaya. This district has a height of approximately 3 meters above sea level. Based on data from the Central Statistics Agency (BPS) for the City of Surabaya 2019, Gunung Anyar District has an area of ​​9.2 square kilometers and is divided into four sub-districts. These include the Kelurahan Rungkut Menanggal, Rungkut Tengah, Mount Anyar and Mount Anyar Tambak (AyoSurabaya.com by Rizma Riyandi). The mangrove's robust root system helps form a natural barrier against storm surges and flooding. River and land sediments are trapped by roots, which protect shorelines and slow erosion. This filtering process also prevents harmful sediments from reaching coral reefs and seagrass beds (Anugerah Ayu Sundari 2019). The method used by remote sensing with Landsat 8 satellite imagery was analyzed using SeaDAS software, it was obtained that the comparison value in each band 2,3,4 and band 5 had differences in each reflectance value. The 2015 satellite image map has the largest value in band_4 with the exponential regression model y = 125.06e-22.13x with R2 = 0.0732, while the 2019 satellite image map which has the largest value is band_4 with the logarithmic regression model y = 141.72ln (x) + 326.3 where R2 = 0.0281. Using the Wilcoxon H1 Test Statistics it is accepted that there is a significant difference between the diameter of mangroves from satellite imagery in 2015 and the diameter of mangroves from satellite images in 2019. Because the number of positive rankings from the diameter of mangrove satellite imagery in 2015 is greater than the diameter of mangroves from satellite imagery in 2019. , it can be concluded that the mangrove area of ​​Wonorejo Surabaya is experiencing fertility.

Abstract

The waters of Teluk Lamong are located on the north sea coast of Surabaya, which is directly adjacent to the Gresik Regency. Lamong Bay is famous as a strategic port place on an International scale. Along the coastal waters of Teluk Lamong, some rivers flow in Lamong Bay. These activities can lead to interaction between fresh water and seawater. This interaction affects the pattern of salinity spread and sea surface temperature in the waters of Teluk Lamong. Salinity and Sea Surface Temperature is one of the biggest factors causing corrosion in the sea that will damage the structure of buildings around the sea. It is expected that in this research as information about the waters of Teluk Lamong for data information or database utilization in the field of civil engineering, among others, port maintenance and coastal building planning. Based on this background, research is needed to monitor the spread of salinity values and sea surface temperatures in Lamong Bay using Landsat 8 satellite imagery for the years 2016 and 2020. The result of modeling the algorithm obtained, the model of the algorithm used to process the salinity of the image is the wavelength Band_4 in the Equation Power with the model algorithm y = 25.437x-0.046, and the degree of determination value R² = 0.5825. While sea surface temperature in power equation with algorithm model y = 302.14x0.0029 and determination value R² = 0.4182. The results of an analysis of the T-test and validation test can be qualified. The results of the analysis of imagery data showed salinity distribution ranged from 27.33 (ppm) to 29.9 (ppm), while sea surface temperatures ranged from 303.95 Kelvin to 304.39 Kelvin.
