BIOMONITORING KUALITAS AIR SUNGAI GANDONG DENGAN BIOINDIKATOR MAKROINVERTEBRATA SEBAGAI BAHAN PETUNJUK PRAKTIKUM PADA POKOK BAHASAN PENCEMARAN LINGKUNGAN SMP KELAS VII
Abstract: This study aims to
determine the quality of the river water Gandong using bio-indicators of
macroinvertebrates and utilize the results of this study to be used as the
building blocks of practical guidance on the subject of environmental pollution
junior class VII. The study was conducted in River Gandong Village.
Ringinagung, Kab. Mabopane divided into 3 stations. Data obtained from direct
observations in the field and laboratory tests. The method used is descriptive
qualitative approach that gives an overview of water quality Gandong River.
Data were analyzed after identifying the calculating method Family Biotic Index
(FBI) based on tolerance index macroinvertebrates.The results of measurements
of physical and chemical parameters, such as temperature for each station in
the range of 25 ° C-26, turbidity range 27-30 cm, the pH range 7, the current
speed 0,16-0,29 m / s, DO 5,8-6 , 1 mg / L. Station II data has physical and
chemical parameters lowest, but some aquatic biota able to survive despite the
type and the amount is not much in the station I and III. As for the
calculation of the FBI, the station I have the 6.39, 6.99 II station, and the
station III 6.82. Water quality station I quite bad, but the quality of the
station II and III declined to poor interpretation of the FBI. Family
macroinvertebrates are most commonly found in every station is family Thiaridae
and Physidae. The results of this study can be used as the building blocks of
practical instructions Chapter Pollution Junior Class VII entitled
"Observing types of animals macroinvertebrates in the river".
