Abstract

Pulau Genting adalah salah satu pulau berpenghuni yang terletak di Kepulauan Karimunjawa bagian timur. Kegiatan pelayaran merupakan kegiatan utama bagi para penduduk Pulau Genting, baik untuk transportasi, jasa angkut, atau sebagai mata pencaharian masyarakat Pulau Genting. Pemetaan kedalaman perairan, terutama pada perairan dangkal perlu dilakukan untuk mendukung urgensi kegiatan pelayaran tersebut. Penelitian ini bertujuan untuk menganalisis dan memetakan perairan dangkal Pulau Genting untuk mendukung alur kegiatan pelayaran. Data yang digunakan adalah data pemeruman lapangan tanggal 26-28 Juni 2022, dan data pasang surut dengan periode 12 Juni–10 Juli 2022. Metode pengambilan data kedalaman lapangan dilakukan dengan alat fishfinder. Sedangkan pengolahan data pasang surut dilakukan dengan metode Admiralty, dan pengolahan data kedalaman lapangan menggunakan koreksi reduksi pasang surut (rt). Nilai kedalaman perairan dangkal Pulau Genting berkisar antara 0 hingga -20 meter, dengan nilai Z0=0,54 meter, HHWL=2,27 meter, MSL=1,77 meter dan LLWL 1,23 meter. Perairan dangkal Pulau Genting sebelah barat memiliki topografi yang lebih landai dibandingkan dengan perairan di sebelah timur. Topografi pantai sebelah timur Pulau Genting, yang cenderung lebih dalam, memungkinkan kapal perikanan kecil dapat bersandar tanpa khawatir kemungkinan kandas. In the eastern Karimunjawa Islands, Genting Island was one of the populated islands. The primary activity for Genting Island residents was shipping, whether it is for personal transit, moving goods, or as a means of support. To support the urgency of these maritime activities, water depth mapping was required, particularly in shallow waters. In order to facilitate maritime activity, this project examine and map Genting Island's shallow water. The data used includes tidal data for the period June 12-July 10, 2022, and field survey data for the period June 26–28, 2022. A fishfinder instrument was used to conduct the method of acquiring field depth data. While implementing the Admiralty method for tidal data processing and tidal reduction correction for field depth data processing. Genting Island's shallow water are between 0 and -20 meters deep, with Z0=0,54 meter, HHWL=2,27 meter, MSL=1,77 meter dan LLWL 1,23 meter respectively. The topography of Genting Island's shallow water to the west was softer than those to the east. Small fishing boats can dock on Genting Island's east coast without being concerned about the potential of running aground due to the terrain, which was often steep.
绘制卡里蒙查瓦群岛云顶岛浅水区地图
地峡是东卡里蒙加瓦群岛的有人居住的岛屿之一。航海活动是岛上居民的主要活动,无论是交通、运输服务还是岛上居民的生计。必须对水务深度进行测绘,尤其是浅水区,以配合水务活动的紧迫性。本研究旨在分析和绘制海峡浅水区以支持航道的情况。所使用的数据包括2022年6月26-28日的实地确认数据,以及6月12日至2022年7月10日期间的潮汐数据。数据挖掘方法是通过鱼翅取样器进行的。而潮汐数据处理是通过金表方法进行的,并使用潮汐还原校正进行现场深度数据处理。岛峡浅水区的深度从0到20米不等,为Z0(0.54米)、HHWL(2.27米)、MSL(1.77米)和LLWL(1.23米)不等。西侧地峡的浅水区地形比东侧更平坦。地形图位于该岛东部的地形图较深,这使得小型捕鱼船可以在不担心搁浅的情况下停泊。在卡里蒙加瓦群岛东部,地峡是最受欢迎的岛屿之一。主要的岛阻力是运输,不管它是个人运输,移动货物,还是意味着支持。为了支持这些海上活动的紧迫性,水的开采主要是可补充的,特别是在低水域。为了缓和海上活动,这个项目考察和地峡浅水区的地图。2022年7月12日至11月10日及22日至6月26 - 28日至2022年12月10日及工作区数据使用。一种鱼翅仪器用来掩盖田野记录的方法。在启动风化数据处理的更新方法和田间数据处理的减重校正。岛低洼的水位在0米和20米深,有Z0= 0.54米,HHWL= 2.27米,MSL= 1.77米,LLWL 1.23米尊重。往西的浅水区的地形比往东的低水位更低。小型渔船可以停靠在东海岸的地峡,而不用担心降雨的潜力。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
