摘要

达拉干市是一个有潜在自然资源待开发的城市。丹戎巴西尔是达拉干镇的一个地区,那里的居民住在沿海地区。本研究旨在利用浮游生物群落结构作为水体生物指标来确定丹戎巴西尔水域的水质。作为研究对象,丹戎巴西尔海域浮游生物群落包括丰度、多样性指数、均匀度指数和优势度指数。本研究采用定量描述的方法,研究地点在两个点进行,即站一位于红树林地区,站二靠近居民区。每两天采样一次,野外采样15次。第一站和第二站浮游植物的种类分别为硅藻科、尾藻科、蓝藻科、介藻科和藻科5个纲,甲壳类浮游动物的种类。浮游植物种类最丰富的是硅藻门和藻门,因为这两个纲在世界上所有的浮游植物中占主导地位。浮游植物丰度值;工作站1为354个细胞/l;在第二站,它是202单元/升。浮游动物的丰度;站1为40 ind/l,站2为38 ind/l。两个站点的多样性指数为中等,均匀度指数为高均匀度,优势度指数为低均匀度。根据浮游生物群落结构的价值,丹绒巴西尔水域被列为轻度污染。塔罗干市丹戎巴西尔水域的环境因子包括1站和2站的物理和化学特性,仍然适合水生生物的生活。

Structure of The Plankton Community In Tanjung Pasir Sea Waters, Tarakan City
: Tarakan City is a city that has potential natural resources to be developed. One of the areas in the town of Tarakan is Tanjung Pasir, where the residents live in the coastal area. This study aims to determine the quality of the waters in Tanjung Pasir by using the plankton community structure as a water bioindicator. As a research object, plankton communities in Tanjung Pasir waters include abundance, diversity index, uniformity index, and dominance index. This study uses a quantitative descriptive method with the research location being carried out at two points, namely Station I in the mangrove area and Station II close to residential areas. Sampling was conducted every two days, 15 times out in the field. The types of phytoplankton found in five classes, namely Bacillariophyceae, Coscinodiscophyceae, Cyanophyceae, Mediophyceae, and Dinophycea lessons and zooplankton from Crustacea class at Station I and Station II. The most abundant types of phytoplankton are found in Bacillariophyceae and Dinophyceae because these two classes dominate all kinds of phytoplankton worldwide. The abundance value of phytoplankton at; Station I was 354 cells/l; at Station II, it was 202 cells/l. The abundance of zooplankton at; Station I was 40 ind/l, and at Station, II was 38 ind/l. The diversity index at the two stations is in the medium category, with the uniformity index being in the high uniformity category and the dominance index at each low. Based on the value of the plankton community structure, Tanjung Pasir waters are classified as lightly polluted. Environmental factors of Tanjung Pasir waters in Tarakan city include the physical and chemical characteristics of Station I and Station II, which are still suitable for the life of aquatic organisms.
