Analysis of relationship between logging activities and water quality in Ulu Muda, Kedah / Nurazizah Zakarya

The objectives of this study are to identify the pattern of logging activities and water
quality in 2011 to 2015 and to map the condition of water quality after logging
activities. The parameters of the water surface are hydrogen potential (pH),
temperature, dissolved oxygen (DO), salinity, conductivity and turbidity, in this study,
there are only three parameters have been utilized which were pH, DO and
temperature in order to identify the parameters in Ulu Muda and Sungai Muda ,
Kedah after the logging activities. These parameters was subsequently interpolated
the Sungai Muda, Kedah, exploiting Kriging method. Kriging method presents the
finest result for the parameters of water quality. This study discusses the details of the
interpolation method and shows the water quality parameters. The result shows the
pattern of logging and water quality and the map of water quality parameters based on
the study area for more efficient of logging activities. The findings of this study were
successfully attained by exploiting Geographic Information System (GIS) techniques
with its capability and efficiency.
