Judul ArtikelTingkat Kualitas Air Menggunakan Metode Family Biotic Index Berdasarkan Keberadaan Makrozoobentos di Sungai Pelus, Kabupaten Banyumas
Abstrak (Bhs. Indonesia)Pencemaran di Sungai Pelus disebabkan oleh faktor manusia dan alam. Pencemaran di sungai akan
mengganggu keseimbangan ekosistem sungai. Salah satu bioindikator pencemaran yang efektif adalah
makrozoobentos. Penelitian ini bertujuan untuk mengukur tingkat pencemaran organik di Sungai Pelus
menggunakan Family Biotic Index (FBI), karena penelitian terkait di Sungai Pelus masih terbatas. Jenis
penelitian ini adalah deskriptif kuantitatif dengan metode purposive sampling. Penelitian dilakukan di
tiga stasiun, dengan tiga kali pengulangan di setiap titik pengambilan sampel. Pengambilan
makrozoobentos dilakukan menggunakan surber net. Parameter kualitas air yang diukur meliputi pH,
oksigen terlarut, kecepatan arus, dan suhu. Perhitungan nilai FBI digunakan untuk mengetahui tingkat
pencemaran organik di Sungai Pelus. Makrozoobentos yang didapatkan terdiri atas 4 kelas, 12 ordo
dengan 17 famili, dengan famili terbanyak yang didapatkan adalah Tubificidae dan Baetidae. Stasiun 1
dan 2 tercemar sedang (FBI=5,06; 5,38), Stasiun 3 tercemar agak berat (FBI=6,2). Indeks
keanekaragaman pada ketiga stasiun tergolong sedang (H’=2,20; 2,03; 1,85), indeks dominansi rendah
(D=0,13; 0,17; 0,17) dan indeks kemerataan tinggi (E=0,78; 0,72; 0,65). Secara umum, kualitas air
menurun seiring meningkatnya pencemaran.
Abtrak (Bhs. Inggris)Pollution in the Pelus River is caused by both anthropogenic and natural factors. River pollution can
disrupt the balance of the river ecosystem. One effective bioindicator of pollution is macrozoobenthos.
This study aims to assess the level of organic pollution in the Pelus River using the Family Biotic Index
(FBI), as related research in the river is still limited. This research is descriptive and quantitative in
nature, using a purposive sampling method. The study was conducted at three stations, with three
replications at each sampling point. Macrozoobenthos were collected using a surber net. Water quality
parameters measured included pH, dissolved oxygen, current velocity, and temperature. The FBI was
used to determine the level of organic pollution in the Pelus River. The macrozoobenthos found
consisted of 4 classes, 12 orders, and 17 families, with Tubificidae and Baetidae being the most
dominant families. Stations 1 and 2 were moderately polluted (FBI = 5.06; 5.38), while Station 3 was
fairly heavily polluted (FBI = 6.20). The diversity index at the three stations was moderate (H′ = 2.20;
2.03; 1.85), the dominance index was low (D = 0.13; 0.17; 0.17), and the evenness index was high (E
= 0.78; 0.72; 0.65). In general, water quality declined with increasing levels of pollution.
