| dc.description.abstract | Aktivitas manusia di sekitar sungai menghasilkan limbah yang dapat
mempengaruhi kondisi kualitas air sungai. Penilaian kualitas air sungai dapat
dilakukan menggunakan pendekatan biologi, salah satunya adalah makrozoobentos.
Penelitian ini bertujuan untuk menentukan status kualitas air Sungai Cihideung
berdasarkan struktur komunitas makrozoobentos menggunakan Lincoln Quality
Index (LQI) dan Stream Invertebrate Grade Number Average Level 2 (SIGNAL 2).
Penelitian dilakukan di Sungai Cihideung, Kabupaten Bogor, Jawa Barat yang
terdiri dari empat stasiun pengamatan. Stasiun 1 hingga Stasiun 4 berada di kawasan
tengah hingga hilir sungai. Struktur komunitas makrozoobentos dianalisis
menggunakan indeks diversitas, yaitu indeks keanekaragaman, keseragaman, dan
dominansi. Penentuan kualitas perairan dilakukan menggunakan indeks biologi,
yaitu LQI dan SIGNAL 2. Makrozoobentos yang ditemukan di Sungai Cihideung
adalah 51 genus, 38 famili, dan 18 ordo yang didominasi oleh Ordo Ephemeroptera
dan Trichoptera. Indeks keanekaragaman dan dominansi makrozoobentos di Sungai
Cihideung termasuk ke dalam kategori rendah. Berdasarkan indeks LQI dan
SIGNAL 2, kualitas air di Sungai Cihideung tergolong ke dalam kategori baik. | id |
| dc.description.abstract | Human activities around rivers produce waste that can affect river water
quality. Assessment of river water quality can be done using a biological indices
based on macrozoobenthos. This study aimed to determine the water quality status
of the Cihideung River based on the macrozoobenthos community structure using
the Lincoln Quality Index (LQI) and Stream Invertebrate Grade Number Average
Level 2 (SIGNAL 2). The study was conducted in Cihideung River, Bogor Regency,
West Java with four observation sites located in the middle to downstream areas of
the river. The macrozoobenthos community structure was analyzed using Shannon
diversity, Evenness, and Dominance indices. Water quality was determined by
biological indices, namely LQI and SIGNAL 2. The macrozoobenthos found in the
Cihideung River were 51 genera, 38 families, and 18 orders, dominated by
Ephemeroptera and Trichoptera. The index of diversity and dominance of
macrozoobenthos in the Cihideung River is in the low. Based on the LQI and
SIGNAL 2 indices, the water quality in the Cihideung River is in the excellent
