ABSTRACT
Drowning is an asphyxia death which is caused by fluid entry into the
respiratory tract. Determination of diatom’s type can be used as support
diagnostic to identify place where the victims drown. The aim of this descriptive
research was to know the form, type, and abundance of diatoms in Kampar river
at Teratak Buluh area. Samples were taken in five stations at the measured depth
by secchi disk in research area. The stations were divided into three sub-sampling
point (left side, center, and right side of the river). Samples were taken by using
water sampler about 50 L and filtered by using planktonnet number 25. Filtered
water samples were entered into sample bottle for 25 ml, given lugol as
preservative, and taken to the laboratory to be analyzed. The examination of
diatoms form and type was done by using binocular microscope and Masaharu
and Yunfang identification book. The abundance of diatoms was counted with
enumeration method randomly using the Sedgwick Rafter Counting Cell (SRCC).
