Abstract

Organofosfat merupakan golongan pestisida yang biasa digunakan dalam aktivitas pertanian. Pestisida ini diketahui memiliki pengaruh toksik terhadap sistem saraf melalui penghambatan enzim cholinesterase. Bahaya paparan organofosfat menyebabkan keracunan dengan gejala mual, muntah, sakit kepala, kejang-kejang, bahkan kematian. Sehingga keracunan organofosfat dapat dinilai dengan kadar enzim cholinesetrase dalam darah. Penelitian ini bertujuan untuk mengetahui gambaran kadar enzim cholineterase pada petani bawang merah di Desa Sumberbulu Kecamatan Tegalsiwalan Kabupaten Probolinggo. Penelitian ini merupakan penelitian deskriptif kuantitatif dengan 17 serum darah dari 24 petani bawang merah yang dipilih secara purposive sampling . Aktivitas enzim cholinesetrase diukur dengan instrumen fotometer biolyzer 100 menggunakan sampel serum darah dan menunjukkan hasil 2 (11,8%) dari 17 (100%) serum darah mengalami penurunan enzim cholinesetrase sedangkan 15 (88,2%) lainnya normal. Hasil analisis statistik hubungan parameter usia (p=0,016) dan kelengkapan APD (p=0,032) menunjukan hubungan signifikan terhadap cholinesetrase. Sedangkan parameter masa kerja (p=0,517) , lama penyemprotan (p=0,233), dan posisi penyemprotan (p=0,668) diketahui tidak memiliki hubungan terhadap penurunan kadar enzim cholinesetrase. Berdasarkan hasil penelitian diketahui penurunan enzim cholinesetrase terjadi pada petani yang memiliki usia 46-60 tahun dengan penggunaan APD tidak lengkap. Sehingga parameter usia dan APD diketahui memiliki hubungan yang signifikan terhadap kejadian penurunan kadar enzim cholinesetrase.
