ABSTRAK
Tujuan penelitian ini adalah untuk menggunakan komunitas makroozoobenthos sebagai
indikator biologi perairan di hulu Sungai Cisadane melalui aplikasi beberapa indeks biologi.
Sampling dilakukan di segmen hulu Sungai Cisadane, Desa Pasir Buncir, Kecamatan
Caringin, Kabupaten Bogor, Jawa Barat pada bulan Juni - Agustus 2006. Indeks biologi yang
digunakan adalah Indeks keanekaragaman, LQI, FBI, Indeks Pantle & Buck, dan SIGNAL 2,
ditambah dengan analisis kualitas air. Hasil penelitian menunjukkan bahwa komposisi dan
kepadatan makrozoobenthos bervariasi antar stasiun dan antar pengamatan. Dari analisis
menggunakan lima metode indeks biologi diduga perairan hulu Sungai Cisadane tercemar
sangat ringan hingga ringan. Metode FBI nampaknya paling sesuai diterapkan di sungai ini,
dan untuk dipakai di Indonesia.
Kata kunci: makrozoobenthos, indeks biologi, pencemaran, sungai
ABSTRACT
The aime of the research was to use makrozoobenthic community as bioindicator of Cisadane
River headstream by some biological indices analyses. Sample collections were made in
headstream segment of Cisadane River in Pasir Buncir Village, Bogor Regency, West Jawa
on June ââ¬â August 2006. Some biological indices were applied, i.e. Shannon-Wiener index,
LQI, FBI, Indeks Pantle & Buck, and SIGNAL 2; in addition, water quality analysis was also
performed. The results showed that the composition and abundance of makrozoobenthic
community varied among sampling stations as well as sampling time. The indices showed
that the river segment was very light until light polluted. FBI seemed to be the suitable index
to determine pollution status in the river, and for applying in Indonesia.
Keywords: makrozoobenthos, biological indices, pollution, stream
