Abstract

Bangka island is the biggest island in Bangka Belitung Province and located between Sumatra and Kalimantan Island. Furthermore, Bangka seas are connecting Natuna sea with Java sea and also become a important part of Indonesia Throughflow. This geographic condition makes Bangka island has a unique oceanography characteristics. However, the information of oceanography database of the Bangka waters remains limited. Thus, the purpose of this research is to develop a oceanography database in Bangka seas to support the development in these region like the zoning plan of Bangka Belitung. Focus area of this study is at the Bangka seas around Bangka Island. The characteristic of oceanography will be discuss in this study covering water quality, tides, waves, and currents. For describe those oceanography characteristic, the data obtained from field observation and numerical methods.. For the current this research using MIKE21 and also using SWAN (Simulating Waves Nearshore) software for wave model. Furthermore, the tidal data from Babel Ocean Observation Science and Technologies (BOOST) Center will be used in this discussion. In addition, the data of water quality are obtained from field observation in several sampling location. From this research, significant wave height (Hs) in Bangka seas around 0.02-1.87 meters and the currents ranges from 0.05-0.72 m/s. The direction of waves and current dominantly to the southeast when the west monsoon and head northwest when the east monsoon direction influenced by wind direction. Furthermore, tides type of Bangka seas is diurnal with around 2.3 m tidal range. For water quality, Bangka seas have around 22C temperature, 22-31/oo salinity, and pH are around 8.

Bangka海域海洋学数据库开发
邦加岛是邦加勿里洞省最大的岛屿,位于苏门答腊岛和加里曼丹岛之间。此外,邦加海连接着纳土纳海和爪哇海,也成为印度尼西亚通流的重要组成部分。这种地理条件使邦加岛具有独特的海洋学特征。然而,邦加水域的海洋学数据库资料仍然有限。因此,本研究的目的是在邦加海域建立一个海洋学数据库,以支持邦加勿里洞分区规划等区域的发展。本研究的重点区域是邦加岛周围的邦加海域。本研究将讨论海洋学的特点,包括水质、潮汐、波浪和洋流。为了描述这些海洋学特征,采用了野外观测资料和数值方法。目前,本研究使用MIKE21和SWAN (simulation Waves Nearshore)软件进行波浪模型。此外,本文还将使用巴别尔海洋观测科学技术中心的潮汐数据。此外,水质数据是通过多个采样点的实地观测获得的。本研究发现,Bangka海域的有效波高(Hs)在0.02 ~ 1.87 m之间,洋流在0.05 ~ 0.72 m/s之间。波浪和海流的方向在西季候风时以东南为主,在东季候风方向受风向影响时以西北为主。此外,Bangka海的潮汐类型为日涨潮,潮差约为2.3 m。就水质而言,Bangka海域的温度约为22摄氏度,盐度为22-31/ 100,pH值约为8。关键词:海洋学数据库;邦加海;海洋学建模
