Abstract

Understanding the dynamics of surface currents in the Bangka Strait is crucial for various maritime and coastal activities. This strait connects Likupang, a super-priority tourism destination, with other islands in North Sulawesi. These activities include navigation safety, inter-island transportation, fisheries, search and rescue operations, and marine pollution control. This study investigated the characteristics of currents in the strait using a hydrodynamic model called Delft3D. The result revealed that the currents exhibit a tidal pattern, with dominant westward flow during floods and eastward flow during ebb. Maximum sea current velocity during spring tide in the second transition monsoon occurred in September 2022, with an average speed of 102.67 cm/s. Current ellipse analysis confirmed the tidal type of the currents.

Abstract

Current is a process of mass transfer of seawater that moves from one place to another continuously or occurs continuously. The current generation factor on the surface of the water is caused by two things, namely the wind and the movement of the rise and fall of sea level. The Lembeh Strait is an Archipelago Port Area and a hub port in Kawasan Timur Indonesia (KTI), as well as an area with local transportation routes for the community. For this reason, it is necessary to research to obtain information about the characteristics and patterns of currents that occur in the Lembeh Strait. This research was conducted using a database of currents and tide data over the period from 2021 to 2022. The research method used is quantitative. Data sources were taken from Badan Meteorologi Klimatologi dan Geofisika (BMKG) Stasiun Maritim Bitung and the Copernicus Marine Service website. These data were analyzed using methods that fit the needs of the data. Flow and Tidal data were analyzed using WRPLOT View, Ocean Data View, Microsoft Excel, and Origin Pro. The results of data processing show the direction and speed of the current as well as the relationship between the tides and currents in the waters of the Lembeh Strait. The scatter plot of currents on the surface layer of the sea is elliptical, this indicates that the currents that dominate in these waters are tidal. So the results of the study show that ocean currents in the Lembeh Strait have current characteristics that are dominantly influenced by tides and the dominant current direction is formed in 2021 and 2022 towards the Southwest and Northeast. Keywords: Current, Tidal Current, Lembeh Strait. Abstrak Arus merupakan proses pergerakan massa air laut yang berpindah dari satu tempat ke tempat lain secara kontinu atau terjadi secara terus-menerus. Faktor pembangkit arus di permukaan air disebabkan oleh dua hal yaitu angin dan pergerakan naik turunnya permukaan air laut. Selat Lembeh merupakan Kawasan Pelabuhan Nusantara dan sebagai salah satu hub port di kawasan Timur Indonesia (KTI), serta sebagai kawasan dengan alur transportasi lokal bagi masyarakat. Untuk itu perlu dilakukan penelitian guna mendapatkan informasi tentang karakteristik dan pola arus yang terjadi di Selat Lembeh.  Penelitian ini dilakukan dengan menggunakan basis data arus dan data pasang surut selang periode waktu dari tahun 2021 sampai dengan tahun 2022.  Metode penelitian yang digunakan adalah metode kuantitatif. Sumber data diambil dari instansi Badan Meteorologi Klimatologi dan Geofisika (BMKG) Stasiun Maritim Bitung dan dari Website Copernicus Marine Service. Data-data tersebut di analisis menggunakan metode yang sesuai dengan kebutuhan data. Data Arus dan Pasang Surut dianalisis menggunakan WRPLOT View, Ocean Data View, Microsoft Excel, dan Origin Pro. Hasil pengolahan data menunjukan arah dan kecepatan arus serta hubungan antara pasang surut dan arus di perairan Selat Lembeh. Scatter plot arus pada lapisan permukaan laut memiliki bentuk ellips, ini menunjukkan bahwa arus yang mendominasi di perairan tersebut adalah arus pasang surut. Sehingga hasil penelitian menunjukan arus laut di Selat Lembeh memiliki karakteristik arah arus dominan dipengaruhi oleh pasang surut dan diperoleh arah arus dominan terbentuk di tahun 2021 dan tahun 2022 menuju ke arah Barat Daya dan Timur Laut. Kata kunci : Arus, Arus Pasut, Selat Lembeh.

Abstract

Tombariri Sub-District is located on the North Coast of the Minahasa Peninsula, directly opposite the North Sulawesi Subduction. North Sulawesi subduction has the potential for earthquakes with a targeted magnitude of M8.5 that can generate tsunamis. In addition, Tombariri Sub-District has a fairly large population density and is located on the coast. This causes the Tombariri Sub-District to be highly vulnerable to tsunami hazards. This study aims to determine the tsunami's estimated maximum height and arrival time. The modeling method in this study is through the Comcot 1.7 application with the worst-case scenario of North Sulawesi Subduction M8.5. The results of this study showed that the maximum height of the tsunami reached 6.17 m. The estimated time of tsunami arrival in Tombariri District ranges from 5-10 minutes. The results of this study can be used as a means of mitigating tsunami disasters. Keywords: Comcot, Tsunami Modeling, Inundation, Numeric Simulation Abstrak Kecamatan Tombariri terletak di wilayah Pesisir Utara Semenanjung Minahasa yang berhadapan langsung dengan Subduksi Sulawesi Utara. Subduksi Sulawesi Utara memiliki potensi gempabumi dengan magnitudo tertarget M8.5 yang dapat membangkitkan tsunami. Selain itu, Kecamatan Tombariri memiliki kepadatan penduduk yang cukup besar dan berada di wilayah pesisir. Hal ini menyebabkan Kecamatan Tombariri memiliki tingkat kerawanan terhadap bahaya tsunami yang tinggi. Penelitian ini bertujuan untuk mengetahui estimasi ketinggian maksimum dan waktu tiba tsunami. Metode pemodelan dalam penelitian ini melalui aplikasi Comcot 1.7 dengan skenario terburuk Subduksi Sulawesi Utara M8,5. Hasil dari penelitian ini menunukkan bahwa tinggi maksimum tsunami mencapai 6,17 m. Estimasi waktu tiba tsunami di Kecamatan tombariri berkisar antara 5 - 10 menit. Hasil dari penelitian ini dapat digunakan sebagai sarana mitigasi bencana tsunami. Kata Kunci : Comcot, Pemodelan tsunami, Simulasi Numerik.

Abstract

The investigation into the physical properties of carbonized mangrove wood (CMW) is essential for its development as an efficient solar heat absorber. This study explores the physical characteristics of CMW and its potential application in solar desalination. Initially, the mangrove wood was cleaned with running water, followed by ultrasonication at a frequency of 42 kHz in 96% ethanol for 5 minutes, and then heated at 125 °C for 2 hours. The carbonization process was conducted in a furnace for 1 hour at temperatures of 400, 500, and 600 °C. The physical properties of CMW were analyzed using an X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), energy dispersive spectroscopy, and scanning electron microscopy (SEM). The findings revealed the formation of a carbon structure at 2 theta angles of approximately 24.08, 23.26, and 23.16°, with carbon contents of 45.05, 36.86, and 39.37%, respectively. CMW was identified as a porous material, making it highly effective for sunlight absorption in seawater evaporation. The hydroxyl content within the CMW structure enhanced its water evaporation capabilities. In experimental investigations aimed at desalinating seawater, a 300-watt halogen lamp was positioned 15 centimeters above the CMW's surface, resulting in an evaporation rate of 5.33 kg.m-2.h-1. CMW shows significant promise as a solar evaporator.
