| dc.description.abstract | Anak Laut Lake is a coastal lake whose existence is widely used as a
tourism area, fishing ground, Fish Landing Base, Floating Net Cages area, around
which there are settlements. Therefore, considering these various activities, water
quality assessment according to its designation needs to be carried out. This study
aimed to determine the characteristics of physical, chemical and biological
parameters and water quality status of Anak Laut Lake that can be used as
information. This research was conducted in March-April 2023 by taking samples
at 4 stations. Measurement of water quality parameters includes physical
parameters (brightness, turbidity, temperature, TSS, TDS, depth, current velocity),
chemical parameters (DO, pH, BOD, BOT, phosphate, nitrate, salinity) and
biological parameters (total coliforms). Determination of water quality index
using the Canadian Council of Ministers of the Environment (CCME) method, the
National Sanitation Foundation-Water Quality Index (NSF-WQI) and the
Pollution Index (PI). The results showed that the waters of Anak Laut Lake were
still within normal limits except for the parameters of nitrate and phosphate in all
measurements, turbidity, BOD and total coliform in several measurements. Anak
Laut Lake is in the status of marginal-poor water quality (CCME), good (NSFWQI)
and lightly-moderately polluted (PI). | en_US |
