Abstract

ABSTRACT The principal of the diatom test in drowning is correlate diatoms from research area and recovered from lung tissue or other organs, reinforce drowning as a cause of death and localize the site drowning. This research is a descriptive study to determine form, type and abundance of diatoms in Limbungan Man Made Lake. It was conducted from April 2012 to May 2012 with two sampling times. Identification of diatom’s species refers to the Masaharu and Yunfang. Abundance was calculated by the method American Public Health Association (APHA) Form of diatoms commonly in research is quadrangle shape. The result of diatom test in Limbungan Man Made Lake show 7 species of diatoms: Asterionella sp, Aulacoseira sp, Melosira sp, Navicula sp, Thalassiosira sp, Fragillaria sp and Diatoma sp. Total diatom’s abundance was 5193,33 cell/L. The highest abundance of diatom is Aulacoseira sp (1688,89 sel/L). Average abundance per station 1298,33 sel/L.
