GAMBARAN DIATOM PADA SUNGAI KAMPAR KAWASAN BULUH CINA SEBAGAI PENUNJANG DIAGNOSIS INDENTIFIKASI LOKASI KORBAN MATI TENGGELAM

Abstract

Description of the diatom species existed in water column were of a key information in forensic science, especially in diagnosing the drowning site. Examining the diatom presence on the tissue, lung, blood, kidney as well as in the lymph of the victim (death person), were performed to confirm whether the death due to drowning or that other reason. Qualitative description of diatom in the part of body victim were compared to that in water, prior to confirmation the location of death. The study were located around Buluh Cina, middle part of Kampar river, in October 2012. The key identification of diatom were referred to Masaharu (1977) and Yungfang (1995), while diatom density were calculated following method of American Public Health Association (APHA). It revealed that 16 diatoms species were identified which consisted of Amphipora sp, Asterionella sp, Cocconeus sp, Gyrosigma sp, Melosira sp, Nitzschia sp, Pleurosigma sp, Ephitemia sp, Eucampia sp, Gomphonema sp, Isthmia sp, Streptotheca sp, Aulacoceita sp, Coconeis sp, Denticula sp and Rhizosolenia sp. Total abundance of diatom account 5801 cells/L. Apparently, Eucampia sp were dominant in the water which abundance of 2002 cells/L which average of all stations were 1933 cells/L.
