Abstract

Sea surface temperature and total suspended solid known as a parameter that is widely used by researchers to detect the quality of water whether it is waters that exist in a river, lakes or on the coast. The changes from the climate will affect the sea surface temperature of water, and whether in total suspended solid the changes can significantly affect the value of sea surface temperatures on the coast. The method developed for analyzing is done by compiling a mathematical model algorithm from the satellite image reflectance data to obtain a model of the SST value and TSS concentration for the same time periods and then analyzing the SST correlation to TSS, and the results shown that TSS which obtained from the most suitable algorithm is linear with the formula TSS = 5799,4x + 13,449 with the correlation value is 0,9275 and for the mapping of sea surface temperature, the most suitable algorithm is linear at a wavelength of 443 nm with the formula SST = -445, 06x + 33,654 and the value of the correlation is 0.6103, and this research could be concluded that the correlation between total suspended solids and sea surface temperature aren’t significant because of the result only have the correlation value 0,329 with the standard error 1,602.

Abstract

Sea surface temperature is one parameter to determine the condition of the ecosystem of a waters, besides that there are other parameters, namely the acidity of sea water which is a number that indicates the degree of an ac id and base of the aquatic environment, where generally the coastal environment has an acidity value below 8 so that changes from this value will disrupt life as a whole for the coastal environment. The purpose of this study is to find a mathematical model of SST and pH that can describe the situation of the coastal area, where as a case study is the Kwanyar coast in Bangkalan district, Madura Island. The method developed here is the least square method to find the optimum mathematical model of these parameters, in addition to that by calculating the algorithm of several channels of visible wavelengths owned by Aqua Modis images which are 412 nm, 531 nm and 667 nm. The results obtained from this study are for the optimum wavelength of sea surface temperature is 667 nm while for pH is 531 nm. From the statistical analysis for the t-test carried out, the results showed no significant correlation between sea surface temperature with a pH value where both parameters showed a statistically low correlation value with an error rate of 5% and the existing Pearson correlation test equipment. The conclusion is that for the Kwanyar Bangkalan coastline the temperature is still in the normal threshold as well as the existing pH value, only these two parameters cannot be stated as a causal relationship, where the temperature rise will have an impact on pH changes and vice versa.

Abstract

Changes in the coastline are a natural phenomenon that often occurs on various coasts where this event has a further effect in the form of sedimentation and erosion along the coast. As a result of this phenomenon, the coast is said to be dynamic towards the various changes that occur, and one of them is the change in sea surface temperature. The purpose of this research is to find a correlation of changes in sea surface temperature to changes in the existing shoreline on the coast of Ujung Pangkah Gresik in addition to calculating the speed of change of the coastline. The method used is the use of remote sensing technology to analyze sea surface temperature and geographic information systems to analyze changes in coastlines. The results obtained from this study are changes in sea surface temperature statistically affect changes in coastlines with an error rate of 5% at the 20 measured observation points. The model used in sea surface temperature is a linear model with an R-value of 0.783, and the change in the coastline at Ujung Pangkah Gresik is 153 meters per year measured between 2019 and 2020. The conclusion obtained from this study is that the increase in sea surface temperature will affect climate change on the coast and will ultimately affect changes in the coastline.

The concentration distribution from total suspended solid is an activity that is quite interesting to study especially in the coastal areas, knowing the distribution value of total suspended solids, it is possible to know the change of ecosystem. The Ujung Pangkah Gresik is an area chosen as an example to determine the distribution concentration of total suspended solid value by making an appropriate mathematical model that can imagine the condition of the body of water in that coastal area. Thus, the purpose of this study was to investigate the mathematics model analysis to imagine the distribution concentration of total suspended solids. The method to model this is by remote sensing that was used in Landsat 8 satellite imagery. In addition, this study used the remote sensing method on the visible light canal (red, green, and blue) to determine the mathematics model analysis of total suspended concentration distribution. The result showed that there was red canal has significant image result compared to another visible canal. The red canal result showed the mathematics model exponential with correlation value R 0.873 has a significant effect to image the total suspended solids concentration distribution. This study concludes that Landsat 8 satellite image can quite effectively and accurately be used to map the distribution of total suspended solid especially in the shallow water environment adjacent to ponds and estuary.

Abstract

Changes in sea surface temperature play an important role in climate change that occurs especially in coastal areas such as Ujung Pangkah Gresik. Changes that occur on the coast will affect the lives of people in the area, and these changes will result in anomalies in climate change and other natural phenomena. The purpose of this study is to find changes in Sea Surface Temperature for 5 years to find the right formula for modeling the impact of these changes, which can be overcome in the future. The method developed here is remote sensing technology with Landsat 8 satellite imagery data to extract the digital number value which is converted into a reflectance value to then look for the optimal mathematical model algorithm with parameters of changes in sea surface temperature. The result of this research is that the wavelength of the red channel is the wavelength that can provide the most optimal results compared to the blue channel, the green channel, and the IR channel. From these wavelengths, an exponential mathematical model and a power model are generated which have the best correlation values among several other calculated models. From this study, it can be concluded that Landsat 8 satellite imagery can provide an overview of changes in sea surface temperature on the coast, especially for shallow waters such as Ujung Pangkah Gresik, so that in the future it can be used as an alternative in decision making in coastal management.

Abstract

Population growth is highly correlated with development activities. Development activities bring changes in land use from one period to the next, bringing relatively high changes, especially changes in land use. Changes in land use that occurs will be a potential for floods, landslides, and prolonged drought if not controlled. It is necessary to do a mapping caused by the impact of the flood disaster, which will later be used as a database which is a regional administration need for land cover information as well as consideration for making a policy for the benefit of the surrounding community. Regional administration needs for land cover information will support planning in an area. Remote sensing is a medium that can monitor the dynamics of land-use change quickly and at a relatively low cost. And by using Sentinel-1 satellite imagery data with the GEE Platform (google earth engine). GEE (google earth engine) is a cloud-based computing platform for performing geospatial analysis, with petabytes of data for scientific analysis and visualization of geospatial data on a global scale. This study aims to identify the distribution of flood areas affected by floods in the Gresik Regency. The results of the study show that the estimated most affected by flooding is the estimated population affected by 6,800,071 Ha. Meanwhile, the next affected area is the Estimated Urban Land of 666,033 Ha. The last estimate affected by the smallest flood is 158,848 hectares of agricultural land. The districts affected by the flood include Cerme, Morowudi, Betatu, Benjeng, Balung Panggang, Gresik Regency.

Abstract

The total suspended solids in the river flow are the source of the sedimentation process, which will lead to the river mouth, namely the coast, which will experience this process on an ongoing basis. In this research, the case study investigated is the flow from the Blega River, which carries the total suspended solids to the coast of Sampang Regency, Madura, where the suspended solids will dissolve in the Sampang coastal waters to the Madura Strait. The purpose of this research is to find out and analyze whether the accumulation of suspended solids is more towards the east or west of the coast of Sampang so that later it can be done to forecast changes in the coastline of the coast. The method used in this research is to utilize remote sensing technology using satellite image data. The results obtained from the measurement of total suspended solids with Aqua MODIS satellite image data in March 2022 showed that more sediment was accumulated in the western part of the coast, so from this phenomenon, it can be predicted that the western coast approaching Bangkalan district will receive sedimentation contributions which will affect the coastline of Bangkalan district in the future. It can also be concluded that the reflectance data of satellite imagery can be used to create an algorithm for the distribution of total suspended solids in sloping coastal areas such as the coast of Sampang, Madura.

Abstract

The coast of Tuban is a fairly dynamic area, where the lives of fishermen depend on fishing efforts. Ecosystem changes that occur in the coastal area of Tuban greatly affect the fishing effort, where one of the parameters that can be observed is the distribution of oxygen content from water bodies on the coast. The purpose of this study was to analyze and map the distribution of acidity content (pH) and its correlation with dissolved oxygen in the coastal area of Tuban. This is based on the fact that research on the distribution of dissolved oxygen has been carried out by many experts, as well as the acidity value of seawater, there have also been those who have done it, only here that needs to be emphasized, that there have not been many dissolved oxygen studies involving other parameters such as acidity pH.
