The coastline is also known as the confluence line between sea water and land which changes position according to position at high tide. Changing the coastline physically is indicated by the occurrence of abrasion and accretion. The coastline when it experiences setbacks is called erosion and the coastline experiences progress called accretion. The purpose of this study was to find out and identify changes in shoreline that occurred in the coastal area of North Surabaya using high-resolution satellite imagery. The method used is to compare the results of the 2012 aerial photography with the World-View 2 satellite imagery in 2017. The results of the study explain the shoreline changes that occur almost along the coast of North Surabaya with an area of total accretion of 143.06 Ha due to additional settlements , mangrove and non-mangrove vegetation and total abrasion area of 44.9 ha caused by port and factory activities. So that changes in the coastline in the coastal area of North Surabaya when viewed based on each sub-district from 2002 to 2017 tend to experience abrasion compared to accretion.

Gelombang permukaan laut adalah salah satu fenomena yang sangat kompleks dan mudah berubah dibandingkan dengan arus dan pasang surut, sehingga untuk memahami secara menyeluruh tentang perilaku dan karakteristik gelombang permukaan laut merupakan hal yang sulit. Gelombang tersebut pada hakekatnya adalah gelombang acak yang terbentuk karena berbagai macam jenis gelombang dengan frekuensi tertentu yang bersuperposisi satu sama lainnya. Sumber pembangkit gelombang tersebut terutama adalah angin, sehingga sering disebut dengan Gelombang Angin (Wind Waves).Secara teoritis, terdapat metode analisis gelombang berdasarkan ketersediaan data dalam suatu perairan, yaitu metode Analisa Gelombang Kurun Waktu Pendek (Short Term Wave Analysis (STWA)) dan metode Analisa Gelombang Kurun Waktu Panjang (Long Term Wave Analysis (LTWA)). Metode STWA adalah melakukan analisa berdasar data gelombang yang pendek, sedangkan metode LTWA dilakukan dengan menggunakan data dalam kurun waktu panjang dan umumnya lebih dari 1 (satu) tahun. Terutama LTWA sangat dibutuhkan untuk mengetahui gelombang yang dipengaruhi oleh musim di Indonesia. Sampai saat ini belum ada data panjang atau kajian gelombang di Indonesia yang menggunakan data panjang karena keterbatasan data detail yang sangat dibutuhkan untuk melakukan analisis tersebut.Untuk mendapatkan data gelombang acak dari berbagai sumber pembangkit gelombang memerlukan alat yang memadai untuk memperoleh datanya. Pada dasarnya ada beberapa jenis alat yang dapat dipergunakan baik di dalam dan di luar untuk memenuhi kebutuhan data tersebut, namun umumnya memerlukan biaya yang tidak sedikit. Sering terjadi bahwa alat yang diperlukan tidaklah sekompleks keperluan untuk pengadaan suatu penelitian yang sederhana, hanya membutuhkan satu atau dua parameter, misalkan untuk mencari data gelombang diperlukan parameter data berupa tinggi air dan waktu, oleh karena itu desain dan alat yang sederhana namun memenuhi kebutuhan untuk pemenuhan data sangatlah membantu dan dapat mengurangi beban biaya penelitian. Pada riset ini diusulkan desain dan pembuatan alat dan sistem gelombang presisi tinggi, dimana diharapkan dalam hitungan detik dapat diperoleh beberapa data gelombang berupa tinggi permukaan air dan waktu pengambilan datanya secara real time dan up to date.

The study of the characteristics of the underwater acoustic wave propagation pattern which includes temperature, salinity and sound speed can be used to detect the presence of submarines. In general, submarines through or hide in shadow areas (shadow zone), which is an area that is not traversed by the propagation of acoustic waves. By knowing the position or area, it can be mapped submarine traffic area. The Monterey -Miami Parabolic Equation (MMPE) program is used to simulate the acoustic wave propagation pattern, which has previously been tested using the Ray Tracing (high frequency) and Normal (low frequency) methods. This study chose the Lombok Strait as a research locus because the area has complex oceanographic dynamics with the meeting of water masses from the Indonesian Ocean and the Pacific Ocean. Simulations are carried out in 2 seasons namely the West and East seasons (2015)(2016). The first simulation of acoustic sources was placed on the island of Bali and propagated to the East. Simulation II of acoustic sources on Lombok Island and the direction of propagation to the West. Simulation III of acoustic sources on Bali Island and propagating to the Southeast, and IV Simulation of acoustic sources on Lombok Island and direction of propagation to the North West. From the simulation results show the formation of shadow zones in all research stations except at the PPSL 15 station and STN 10 station. The submarine traffic lane map is made based on the shadow zone area formed, and the determination of the installation site of submarine monitoring equipment is determined based on the minimum area / there is no shadow zone. The area is the area
