Rahayu, Ririn Sri (2017) Evaluasi Kualitas Air Di Mata Air Kendedes Dan Salurannya Berdasarkan Beberapa Indeks Biotik Dari Makroinvertebrata Bentos. Sarjana thesis, Universitas Brawijaya.
Abstract
Aktivitas manusia yang beragam di sepanjang aliran Mata Air Kendedes berpotensi menimbulkan terjadinya pencemaran air. Tujuan dilakukan penelitian ini adalah mengevaluasi dampak aktivitas masyarakat di sepanjang aliran Mata Air Kendedes terhadap penurunan kualitas air berdasarkan makroinvertebrata bentos sebagai bioindikator dan pelengkap dari pemantauan secara fisik-kimia. Pengambilan sampel air dan makroivertebrata bentos dilakukan di lima stasiun yang masing – masing terdapat aktivitas berbeda, pengambilan makroinvertebrata bentos sebanyak ±100 individu. Pengukuran parameter fisik-kimia air meliputi BOD, DO, konduktivitas, suhu, pH, turbiditas, kecepatan arus dan debit. Selanjutnya dilakukan identifikasi dan dicari nilai indeks HBI, FBI, H dan ASPT. Hasil penelitian menunjukkan stasiun 1 dan 2 memiliki kualitas air yang bagus (nilai FBI 4,99-4,96 dan nilai HBI 4,99-4,94). Stasiun 3 – 5 digolongkan memiliki kualitas air yang buruk (nilai FBI 7,03-8,81 dan nilai HBI 6,98-7,82). Berdasarkan nilai H stasiun 1 dan 2 belum tercemar (nilai H 2,24-2,13) sedangkan stasiun 3 - 5 tercemar (nilai H 1,23-1,97). Berdasarkan nilai ASPT stasiun 1 – 3 memiliki kualitas air yang tercemar ringan (nilai ASPT 4,57-4,83) stasiun 4 dan 5 tercemar berat (nilai ASPT 3,25-3,75). Hasil pemantauan kualitas fisik-kimia air menunjukkan nilai pH dan suhu setiap stasiun memenuhi nilai baku mutu, nilai DO memenuhi baku mutu kelas II dan III, sedangkan nilai BOD memenuhi baku mutu kelas I dan II. Berdasarkan beberapa indeks nilai biotik dan kualitas air terbukti bahwa semakin jauh dari mata air kondisi perairan semakin buruk, karena telah dipengaruhi oleh aktivitas manusia.
English Abstract
Human activities along the flow of Kendedes Spring water have the potential to cause water pollution. The purpose of this study is to evaluate the impact of community activities along the flow of Kendedes Spring water to degradation of water quality based on benthic macroinvertebrates as bioindicator and complement of physicochemical monitoring. Water and benthic macroivertebrate sampling were conducted in five stations which have different human activities in the surounding. We take sample of benthic macroinvertebrate about ±100 individuals. The measurements of water physicochemical parameters include BOD, DO, conductivity, temperature, pH, turbidity, flow velocity and water discharge. Data of benthic macroinvertebrate then be used to calculate the value of some of biotic indices (HBI, FBI, H and ASPT). The results showed that based on FBI and HBI values, station 1 and 2 had good water quality (FBI 4.99-4.96 and HBI values (4.99-4.94). Station 3 - 5 was classified as having poor water quality (FBI 7.03-8.81 and value HBI 6.98-7.82). Based on the value of H stations 1 and 2 have not been contaminated (H value of 2.24-2.13) while station 3-5 is polluted (H value 1.23-1.97). Based on ASPT value, water quality in station 1 - 3 categorized as slightly contaminated (ASPT value 4.57-4.83), station 4 and 5 is heavily polluted (ASPT value 3.25-3.75) .The monitoring result of physicochemical water quality showed that pH value and temperature of each station has meet the quality standard value, DO value was categorized as class II and III quality standard, while BOD value inluded in class I and II. Based on several biotic indices values and water quality it is evident that the farther from the springs the waters condition was getting worse. It is because of human activities.
