    GAMBARAN HASIL PEMERIKSAAN BAKTERI COLIFORM PADA SUMBER MATA AIR BUKIT SIKUMBANG DESA PULAU SARAK RUMBIO KECAMATAN KAMPAR TAHUN 2018
    (2019-11-16) Marisa, Marisa; Shinta, Dewi Yudiana
    Parameters that indicate that a source of water is polluted, one of which is coliform bacteria. Coloform bacteria are a group of bacteria that live in the digestive tract. spring water in sikumbang hill village of sarak island, kampar sub-district is used by people in the village for drinking water sources. springs emerge from natural soil. This study aims to determine the bacteriological quality of drinking water from the spring waters of the sikumbang hill village of Sarak Island. This research method is the MPN (most probable number) method, the sample is taken from eleven drinking water managers sourced from the sikumbang hill springs by tap water in a distribution basin. the results showed that 90% of samples were contaminated by coliforms, so they did not meet the health standards set by the Republic of Indonesia's Ministry of Health in "Permenkes" no: 492 / menkes / per / IV / 2010 ie in this case stating that the spring source of the hill village sikumbang village sarak island is not suitable for consumption directly by the community but must be cooked before consuming it.

    Hubungan Kadar Cholinesterase Dan Jumlah Leukosit Kasus Keracunan Pestisida Pada Petani
    (wahyu sari yeni, 2019-01-10) Shinta, Dewi Yudiana; Sonata, Herix
    Indonesia is one of the agricultural countries that use pesticides high enough to control various pests that can reduce the population of plant pest organisms (OPT). Cholinesterase in the blood will bind, because in blood it is generally used as a parameter of pesticide poisoning. Cholinesterase is also synthesized in the liver or liver, blood plasma, and red blood cells. Leukocytes in the blood of farmers who experience pesticide poisoning will increase. The purpose of this study was to analyze the relationship between the number of leukocytes and cholinesterase cases of poisoning in farmers. This study uses a blood sample of farmers as many as 20 people. The results showed that the correlation test of Pearson test results showed p = 0.563 and r = 0.137. This means that there is no significant relationship between the number of leukocytes and cholinesterase cases of pesticide poisoning in farmers with very weak and insignificant correlation strengths. The use of pesticides to control plant pests contains the risk of accidents in humans in the form of chronic / acute poisoning and / or death. The severity of the level of poisoning is related to the level of inhibition of cholinesterase in the blood.

    KERACUNAN PEPTISIDA DAN KADAR HEMOGLOBIN PADA PETANI CABE
    (2019-11-16) Shinta, Dewi Yudiana; Sonata, Herix
    The use of chemical pesticides can cause poisoning and death in humans. Pesticides can pollute the environment, especially water bodies. The impact of using pesticides can cause irritation of the lining of the eyes or skin, disruption of the hormone system, organ failure and death. Chronic poisoning due to exposure to pesticides in the form of abnormalities in blood profiles such as hemoglobin, neutrophils, leukocytes, nervous system and digestive system. The influence of pesticides on hemoglobin levels causes decreased production or increased destruction of red blood cells and makes the formation of methemoglobin in red blood cells causing hemoglobin to become abnormal and unable to carry out its function in delivering oxygen. This study aims to analyze the relationship of pesticide poisoning with hemoglobin levels in chilli farmers. The benefits of this research can be a concern for the community in the use of pesticides. Examination of pepticide levels in the blood is used by the comparator method (comparative glass), and examination of hemoglobin levels using the sahli method. Based on statistical tests, a significant value of 0.0363 means <0.05 means that there is no effect of hemoglobin levels on pepticide levels. But when viewed from hemoglobin levels, there is an influence of hemoglobin levels on pepticide levels in the blood so that that can cause low hemoglobin levels. So it can be concluded that the significant value of the SPSS test cannot be used as a guideline because of the insufficient number of respondents. This research is expected to be one of the references in the use of chemical pesticides

    PEMANFAATAN LIMBAH KULIT BUAH MELINJO (Gnetum gnemon L ) SEBAGAI ADSORBEN LOGAM BERAT Pb (TIMBAL)
    (2016-07-30) Shinta, Dewi Yudiana
    Tanaman melinjo dapat tumbuh dengan baik di Indonesia yang tersebar di pulau Sumatra dan Jawa. Di Sumatera Barat, melinjo mampu menghasilkan buah sebanyak 80 - 100 Kg perhari, dan akan menghasilkan juga limbah kulit yang banyak setiap harinya. Limbah ini belum dimanfaatkan oleh masyarakat setempat. Penelitian ini bertujuan untuk memanfaatkan limbah kulit melinjo sebagai penyerap logam berat hasil dari buangan laboratorium untuk skala kecil.Penelitian ini menggunakan metode eksperimen dengan menggunakan Spektrofotometer Serapan Atom sebagai alat untuk analisa logam berat Pb. Hasilnya dianalisis dengan statistik uji ANNOVA dua arah tanpa interaksi.Kadar logam Pb yang dapat diserap oleh serbuk kulit buah melinjo adalah 13,81 ppm untuk mesh 160 konsentrasi 50 ppm; 6,45 ppm untuk mesh 160 konsentrasi 75 ppm; 0,89 ppm untuk mesh 160 konsentrasi 100 ppm; 32,26 ppm untuk mesh 50 konsentrasi 50 ppm; 76,91 ppm untuk mesh 50 konsentrasi 75 ppm; 88,87 ppm untuk mesh 50 konsentrasi 100 ppm. rata-rata penyerapan logam Pb pada pH 3 dengan konsentrasi logam Pb yang terserap 89,040 ppm, pada pH 7 sebanyak 96,009, dan pH 10 sebanyak 89,813 ppm.Analisis ANNOVA didapatkan nilai Fhitung (mesh)=7,96 dan Ftabel =98,49; Fhitung (konsentrasi) = 0,42 dan Ftabel = 99,00. Hasil penelitian ini dapat disimpulkan bahwa ada perbedaan yang signifikan antara variasi mesh dan konsentrasi terhadap penyerapan logam oleh serbuk kulit buah melinjo dan tidak ada pengaruh pH terhadap penyerapan logam berat Pb.
