Distribusi Spasial Kualitas Perairan Pantai Pasir Mayang Kabupaten Kayong Utara Provinsi Kalimantan Barat

Abstract

Monitoring the quality and condition of waters is an important
activity to carry out, especially in coastal waters which are very
easily contaminated and prone to pollution. The waters of Pasir
Mayang Beach are influenced by inputs from rivers and the
activities of coastal communities, which in turn affect the water
quality and aquatic organisms. The purpose of this study was to
determine the condition of water quality using seawater quality
standards and map them spatially. Water quality parameters
surveyed included temperature, salinity, pH, oxygen level and
brightness which were measured at 17 survey locations. The
survey method used was direct data measurement and the data
was grouped into tabular form using Ms. Excel 2010 and the
results were compared and matched with seawater quality
standards stipulated by the Minister of Environment Regulation
No. 51 of 2004. Spatial distribution was carried out using ArcGIS
10.4 software and interpolated using the inverse distance
weighting (IDW) method. Measurement and analysis results were
obtained for temperature parameters between 30-31.6 °C.
Salinity 11.3 to 21.7 ‰. pH 7.0-7.9;DO 2.1-3.6mg/L. Based on
the research results, the following conclusions can be drawn:
Some of the seawater quality of Pasir Mayang Beach still meets
the established quality standards, including temperature and pH,
so that it can be further classified according to its function.
However, there are several parameters that do not meet quality
standards, namely: Salinity, DO and Clarity. For theeDO
parameter, thereeareeseverallresearchhstationssthat are still
within or below the quality standard.
