Rahmawati, NovianaNur (2015) Struktur Komunitas Dan Indeks Biotik Makroinvertebrata Bentos Di Saluran Mata Air Nyolo Desa Ngenep Kecamatan Karangploso Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui profil struktur komunitas dan beberapa indeks biotik makroinvertebrata bentos untuk evaluasi kualitas air di mata air Nyolo dan salurannya yang terletak di Desa Ngenep Kecamatan Karangploso Kabupaten Malang. Pengambilan sampel makroinvertebrata bentos dilakukan pada enam stasiun meliputi sekitar mata air Nyolo (stasiun satu dan dua), Curah Glogo (stasiun tiga dan empat), dan Curah Lang-lang (stasiun lima dan enam). Sampel diambil sebanyak ±100 individu/stasiun menggunakan Jaring Surber dan handnet. Pengumpulan data tiap stasiun meliputi kekayaan taksa, INP (Indeks Nilai Penting), indeks diversitas (H’), FBI (Family Biotic Index), HBI (Hilsenhoff Biotic Index), ASPT (Average Score Per Taxa), persentase EPT (Ephemeroptera, Plecoptera, dan Trichoptera) dan kekayaan taksa EPT (EPT richness). Pengelompokan lokasi penelitian digunakan analisis Cluster dan Biplot. Hasil penelitian menunjukkan bahwa kekayaan taksa makroinvertebrata bentos yang ditemukan sebanyak 28 taksa dan bervariasi pada tiap stasiun. Baetidae, Caenidae, Melanoides tuberculata, Odonata jenis Euphaeidae, Planaria dan Hydropsychidae jenis Cheumatopsyche sp. ditemukan di keenam stasiun. Pada setiap stasiun didominasi oleh jenis yang berbeda, di stasiun satu terdapat kodominasi Chironomidae dan Cheumatopsyche sp., stasiun dua didominasi oleh Melanoides tuberculata, stasiun tiga terdapat kodominasi Lymnaea rubiginosa, Thiara scabra, dan Dugesia trigina, stasiun empat terdapat kodominasi Cheumatopsyche sp. dan Simuliidae, dan di stasiun lima dan enam didominasi oleh Baetidae. Kualitas air berdasarkan struktur komunitas dan indeks biotik pencemaran bahan organik yaitu agak tercemar untuk stasiun empat, lima dan enam, tercemar ringan untuk stasiun satu, dan tercemar sedang untuk stasiun dua dan tiga.
English Abstract
The aim of this research is to determine the community structure of benthic macroinvertebrates and some biotic indices for evaluation the water quality in Nyolo springs and its drains located at Ngenep village, Karangploso Malang. Sampling of benthic macroinvertebrate conducted in six location included springs (station one and two), Curah Glogo drains (station three and four) and Curah Lang-lang drains (station five and six). Samples of benthics macroinvertebrate were taken approximately ±100 individues per station using Surber net and handnet. Data monitoring results were used to analyze the profile of biodiversity for each station included taxa richness, INP (Importance Value Index), index of diversity (H ), FBI (Family Biotic Index), HBI (Hilsenhoff Biotic Index), ASPT (Average Score Per Taxa), percentage of EPT (Ephemeroptera, Plecoptera, and Trichoptera) abundance, and EPT richness. Grouping of research location was found by cluster and Biplot by Principle Component Analysis (PCA). The results showed that the taxa richness of benthic macroinvertebrate were 28 taxa and there was variation among stations. Baetidae, Caenidae, Melanoides tuberculata, Odonata (Euphaeidae), Planaria and Hydropsychidae from species Cheumatopsyche sp. found in the all station. Each station is dominated by different taxa, at first station is codominated by Chironomidae and Cheumatopsyche sp., second stations is dominated by Melanoides tuberculata, third station is codominated by Lymnaea rubiginosa, Thiara scabra, and Dugesia trigina, fourth stations is codominated by Cheumatopsyche sp. and Simuliidae, and the last fifth and sixth stations are dominated by Baetidae. Based on the community structure and calculation of the benthic macroinvertebrates biotic indices, station four, five and six were categorized as organic pollution unlikely, station one was possible slight organic pollution, and station two and three was included in the category fairly substantial pollution likely.
