Analisis Parameter Fisika-Kimia sebagai Salah Satu Penentu Kualitas Perairan Batang Palangki Kabupaten Sijunjung, Sumatera Barat
Abstract: The purpose of this study was to analyze the
physical and chemical parameters of waters Palangki Sijunjung Batang West
Sumatra. Palangki rod is one of the river located in Palangki Sijunjung district,
West Sumatra, which is used by residents as one for gold mining. Determination
of sampling stations porpusive water sampling stations chosen three that are
considered to represent perarian include: stasin I location (center of gold
mining), the second station location (downstream part of the river) and the
station III (upper part), each taken three bags station water samples at
random. Further water samples taken to the laboratory for chemical analysis.
The results showed that the outcome measure physical parameters such as: water
temperature ranges between 25-26 ° C, the transparency of between 10-30 cm,
humidity 60-65 g / m3, the color of the water was murky, and the current
velocity ranging between 8-15 m / sec. Furthermore, chemical factors waters
Trunk Palangki found that the average water pH 6, dissolved oxygen (DO) ranged
from 5.25 to 5.96 mg / l and the quality standard of 5 mg / l, BOD ranges from
2.80 to 3, 49 mg / l and the quality standard of 3 mg / l, COD ranged from
47.05 to 78.25 mg / l and 25 MGL quality standards, total organic material (TOM)
berkiar between 9.61 to 12.10 mg
/ l and mutu110 raw mg / l. as
well as the levels of Mercury (Hg) 0.098 to 0.208 mg / l and quality
standard of 0.002 mg / l. From the results of this study concluded that
concentrations of mercury (Hg) in the water exceeds the threshold value means
heavy metal contaminated.
