World Health Organization (WHO) memperkirakan kasus keracunan pada pekerja pertanian karena pestisida sebanyak 1-5 juta orang per tahun dan tingkat kematian mencapai 220.000 korban jiwa. Paparan pestisida bertindak sebagai senyawa asetilkolinesterase (Ach), yang mengurangi aktivitas kolineterase dalam darah. Kolinesterase adalah salah satu bentuk enzim yang berasal dari katalis biologis dalam jaringan manusia yang berperan membantu otot dan kelenjar saraf bekerja secara teratur dan harmonis. Jika aktivitas kolinesterase jaringan manusia dikurangi dengan baik ke tingkat lebih rendah, hal ini akan mempengaruhi gerakan sadar atau kasar dari serat otot. Tujuan penelitian ini adalah untuk mengetahui kadar kolinesterase dalam darah menggunakan metoda komperator (kaca pembanding) pada petani sayur berdasarkan lama paparan pestisida organofosfat. Metode yang dilakukan pada penelitian ini adalah deskriptif dengan menggunakan 20 sampel. Berdasarkan dari uji statistik didapatkan nilai sig 0,003 < 0,05 yang artinya bahwa perbedaan kadar kolinesterase berdasarkan lama paparan pestisida pada petani sayur di Kabupaten Solok memiliki perbedaan atau adanya pengaruh sebesar 0,621 nilai tersebut setelah dikonsultasi dengan tabel interprestasi angka “r” (pedoman derajad hubungan) 0,621 berada antara (0,60-0,799) yang interprestasinya termasuk dalam kategori kuat.
