Wisata mangrove Wonorejo sering juga disebut sebagai Wisata Anyar Mangrove (WAM) atau mangrove Gunung Anyar karena memang kawasan hutan mangrove Wonorejo juga berada di kawasan Gunung Anyar. Kawasan hutan mangrove atau hutan bakau ini pada awalnya dibangun oleh lembaga masyarakat Wonorejo karena mereka prihatin akan kondisi pantai Timur Surabaya yang sering kali mengalami abrasi. Selain itu juga untuk menjaga keberadaan hutan di Surabaya yang semakin berkurang. Sekarang pengelolaan kawasan hutan mangrove Wonorejo ini sudah diambil alih oleh pemerintah lokal dan dikembangkan terus menerus, karena kawasan hutan ini tidak hanya berpotensi sebagai kawasan wisata tetapi juga sebagai kawasan perlindungan bagi satwa liar. Untuk mengetahui kondisi saat ini apakah wisata mangrove ini mengalami kesuburan atau ketidak suburan, dilakukan penelitian dengan cara membandingkan data antara data citra tahun 2015 dengan data citra tahun 2019 dengan menggunakan citra satelit dan metode pengujian Wilcoxon. Analisa dengan sofware SeaDAS dan metode Wilcoxon. Menghasilkan persamaan regresi pada setiap band, band-5 memberikan nilai R yang terbaik. Model Algoritma Citra Landsat 2015 adalah Power D = 7.588(R_band5)-1.126dengan nilai R= 0.7994 dan Model Algoritma citra Landsat 2019 adalah Power D= 6E + 07(R_band5)8.7054 dengan nilai R=0.6352. Pengujian Wilcoxon menunjukkan hasil bahwa H1 diterima artinya ada perbedaan yang signifikan antara Diameter mangrove dari citra satelit tahun 2015 dengan Diameter mangrove dari citra satelit tahun 2019.Sedangkan jumlah rangking Positif dari Diameter mangrove citra satelit tahun 2015 lebih besar dibandingkan dengan Diameter mangrove dari citra satelit tahun 2019, sehingga dapat ditarik kesimpulan bahwa kawasan mangrove Wonorejo Surabaya mengalami perubahan yaitu kesuburan.

Ecosystems in aquatic environments are distinct from ecosystems on land. Changes that occur in ecosystems in aquatic environments affect the lives of biota in these waters, including the fish used as a food source in fishing communities in coastal areas. This study aims to determine the role of remote sensing in mapping and analyzing the relationship between the parameters of sea surface temperature and chlorophyll-a concentrations on the coast. The correlation of sea surface temperature with chlorophyll-a concentrations is modeled via linear regression. An analysis of variance test is performed to establish the suitability of the temperature data for the data on chlorophyll-a concentrations and to map the concentration distribution with the SeaDAS program. Results revealed a linear Chlor (mg/m3) = 63,695 − 2,014T (°C) with an R2 coefficient value of 0.325. This work concludes that Terra MODIS satellite imagery can be used to predict the distribution of chlorophyll-a concentrations on the coast, although its results require further comparison with those of other sensors.

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.

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.

Ujung Pangkah Gresik is an area where there is an estuary of a vast river, the Bengawan Solo river. This area annually sends sediment loads transported by the Bengawan Solo river to the Ujung Pangkah estuary so that gradually accumulation occurs, which results in changes in the morphology of the coast on the edge of the Ujung Pangkah coast, Gresik. This study seeks to see the side of shoreline changes on the Ujung Pangkah coast for five years. Then take the change model as a mathematical model that can describe the speed of shoreline change per year using the Lagrange polynomial interpolation method for degrees 1, degrees 2, and degrees 3. The results of shoreline changes that occur are obtained by the Lagrangge polynomial algorithm of degree 3 with R2 of 0.3747 which has a better correlation than degree 1 (0.0313) and degree 2 (0.3741). The results of this study obtained a mathematical model with a Lagrange polynomial approach where degree 3 has the best correlation among other models. This study concludes that by using a mathematical model, an overview of the process of change or natural phenomena can be obtained, where the existing model can predict future changes in the existing coastline.

Chlorophyll-a mapping is widely used in the coastal environment. The mapping results can be utilized as guidance for fishing activities. The presence of chlorophyll-a in phytoplankton is much investigated concerning the existence of fish as a source of livelihood for fishermen around the globe. One method extensively developed is the use of satellite imagery to map the chlorophyll-content in the coastal region from a small area to a global scale, such as Aqua MODIS image data. This study aims to monitor the distribution of chlorophyll-a on the north coast and south coast of Lombok island. Analysis of variance and parametric statistical tests with t-distribution was utilized to examine the correlation between the two types of chlorophyll-a distribution of the coast area, Lombok Island. The result shows that the distribution of chlorophyll-a concentrations on the north coast and the south of the coast is not the same abundance; the south coast of Lombok island has smaller variances, with the concentration distribution is relatively the same. It differs from the north part; the distribution shows less diversity. This result indicates that a reasonably wide interval wherein some coordinates has a relatively diffuse chlorophyll-a concentration with a sufficiently high distribution level. Analysis of variance result also shows that both the north and south coasts have different fertility levels for their coastal waters, which are characterized by the growth rate of chlorophyll-a on the surface water along the coastal region examined
