Abstract

Sungai memiliki peranan penting dalam kehidupan manusia dan mahluk hidup lainnya. Makrozoobentos menempati habitat di dasar sungai. Keanekaragaman makrozoobentos berperan penting pada ekosistem sungai. Penelitian ini bertujuan untuk menganalisis keanekaragaman makrozoobentos Sungai Lowatag berdasarkan Indeks Keanekaragaman Shannon-Wiener (H’). Penelitian ini menggunakan metode purposive random sampling di sepanjang Sungai Lowatag. Stasiun penelitian sejumlah tiga stasiun yaitu hulu, tengah dan hilir dengan ulangan di tiap stasiun berjumlah tiga kali ulangan. Makrozoobentos yang ditemukan di Sungai Lowatag memiliki kelimpahan total sebanyak 1.115 individu (35 taksa). Kelimpahan makrozoobentos di Stasiun I, II, dan III berturut-turut yaitu 26,37%, 44,39 % dan 29,24%. Nilai Indeks Keanekaragaman Shannon (H’) dari Stasiun I, II dan III berturut-turut yaitu 2,97; 2,69; dan 2,61. Nilai H’ untuk Sungai Lowatag yaitu 2, 94Rivers have important role for humans and wildlife. Macrozoobenthos occupies habitat at the bottom of the rivers. Biodiversity of macrozoobentos is important in river ecosystem. This study aimed to analyze biodiversity of macrozoobenthos of Lowatag River based on the Shannon-Wiener Diversity Index (H’). This study used a purposive random sampling method along Lowatag River. There were three research stations, namely upstream, middle and downstream with three replications each station. Macrozoobenthos found in the Lowatag River have total abundance of 1,115 individuals (35 taxa). The abundance of macrozoobenthos at Station I, II, and III were 26.37%, 44.39% and 29.24% respectively. The Shannon Diversity Index (H ') values of Station I, II and III respectively were 2.97; 2.69; and 2.61. The H’ value of Lowatag River was 2. 94

河流在人类和其他生物的生活中扮演着重要的角色。Makrozoobentos栖息在河床上。宏观生物多样性在河流生态系统中扮演着重要的角色。这项研究的目的是根据shan非wiener多样性指数(H’)分析Lowatag河的宏观变形虫多样性。这项研究采用了低水位河边随机采样的方法。研究站由上、中、下三站组成，每个站有三次重复。在洛阿图格河中发现的宏观变形虫总共有1115人(35塔萨)。第1、2、3站、第26.37%、44.39 %和29.24%的宏观缩放指数。香农多样性指数(H’)，连续第二站和第三站的值为2.97;2,69;和2,61。H '代表低水位河流2,94里弗斯对人类和野生动物有重要的角色。Macrozoobenthos在河流底部的栖息地。macrozoobentos的生物多样性在河流生态系统中是重要的。这是一项研究，研究对象是基于shan非wiener多样性指数的macrozoobends生物多样性分析。这项研究用的是一种随机抽样的方法。有三个研究站，namely upstream，中和下流带有每个车站的三个复制品。在low - River发现的Macrozoobenthos总共有1.115个个人。macrozoobenthos在I、II和III站的abundance是26.37%、44.39%和29%。Shannon多样性指数是2。97;2 . 69;和2 . 61。低水位的值是2。94
