    GAMBARAN DIATOM DI PERAIRAN SUNGAI KAMPAR KAWASAN DANAU BINGKUANG SEBAGAI PENUNJANG DIAGNOSIS IDENTIFIKASI TEMPAT KORBAN TENGGELAM
    (2013-01-22) Wibowo, Yogi
    Drowning death have a meaning as a death cause there are an obstruction in our respiratory tract by liquid especially water.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 Danau Bingkuang 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).

    GAMBARAN DIATOM DI PERAIRAN SUNGAI KAMPAR PADA KAWASAN TERATAK BULUH SEBAGAI PENUNJANG DIAGNOSIS IDENTIFIKASI TEMPAT KORBAN TENGGELAM

    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).

    GAMBARAN DIATOM PADA PERAIRAN DANAU BUATAN LIMBUNGAN SEBAGAI PENUNJANG DIAGNOSIS IDENTIFIKASI TEMPAT KORBAN MATI TENGGELAM
    (2012-12-03) Abizar, Hafizhah
    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.

    GAMBARAN DIATOM PADA PERAIRAN SUNGAI SIAK KECAMATAN MEMPURA KABUPATEN SIAK SEBAGAI PENUNJANG DIAGNOSIS IDENTIFIKASI TEMPAT KORBAN TENGGELAM
    (2013-01-22) Ramadhan, Diko Anugrah
    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 in Siak river on Mempura district, Siak Regency, in May and June 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 26 diatoms species were identified which consisted of Actynodiscus sp, Amphora sp, Asterionella sp, Aulacoseita sp, Cocconeis sp, Coscinodiscus sp, Cyclotella sp, Dactyliosolen sp, Diatoma sp, Eucampia sp, Eunotia sp, Fragillaria sp, Hyalodiscus sp, Isthmia sp, Melosira sp, Nitzschia sp, Navicula sp, Planktoniella sp, Pleurosigma sp, Rhizosolenia sp, Streptotheca sp, Stephanodiscus sp, Surirella sp, Tabellaria sp, Triceratium sp, Thalassiosira sp. Total abundance of diatom account 5987,5 cells/L. Apparently, Aulacoseira sp were dominant in the water which abundance of 812,5 cells/L which average of all stations were 1197,5 cells/L.

    GAMBARAN DIATOM PADA SUNGAI INDRAGIRI KAWASAN AIR MOLEK SEBAGAI PENUNJANG DIAGNOSIS IDENTIFIKASI LOKASI KORBAN MATI TENGGELAM
    (2013-02-19) Gaoss, Betwindo Arman
    Diatoms examination in the body of drowning death was an important procedure in determination of death location. The presence of diatoms found in the lung and the other organs were the intravital sign, proving the victim were alive on the water. Determination of diatoms species could be used as a supportive diagnostic in identifying drowning site by comparing diatoms between the body and water. The aim of the present research was to find out the species and abundance of diatoms in Indragiri river especially at Air Molek area. Samples were taken from three stations which decided purposively in December 2012. The identification of diatoms was done by using a binocular microscope. Species identification were following Masaharu (1977) and Yunfang (1995) guide book. The abundance was calculated following American Public Health Association (APHA). The results showed that 12 species diatoms were found, namely: Isthmia sp, Aulacoseira sp, Diatoma sp, Melosira sp, Eunotia sp, Tebellaria sp, Gyrosigma sp, Achnantes sp, Fragilaria sp, Pinularia sp, Cocconeis sp dan Campylodiscus sp. Aulacoseira sp and Diatoma sp. Total abundance of diatoms account were 3391 cells/L, with the Diatoma sp were the dominant diatoms in the water which abundance of 1242 cells/L.

    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.
