Prolonged exposure to chlorpyrifos, a commonly used pesticide, can lead to pesticide residues on fruits and alter metabolic processes in the body. This study aims to examine the effect of prolonged low dose chlorpyrifos exposure on total cholesterol levels in wistar rats. A posttest-only randomized control group design was employed. 30 wistar rats were assigned to one of five groups: a normal control group (KN) and four groups exposed to low dose chlorpyrifos for 7 days (K1), 14 days (K2), 28 days (K3), and 56 days (K4). This research was conducted from February to May 2023 at the Faculty of Medicine, University of Jember. The results from the LSD post hoc test show significant differences between the normal control group and the K1 and K2 exposure groups. Moreover, significant differences were observed between the K3 exposure group and the K1 and K2 exposure groups, as well as between the K3 exposure group and the K2 exposure groups. In conclusion, exposure to low chlorpyrifos doses significantly increases total cholesterol levels at 7 and 14 days, followed by a decrease at 28 days and a subsequent increase at 56 days of exposure.

Efek Pajanan Lama Klorpirifos Dosis Rendah terhadap Kadar Kolesterol Total Tikus Wistar
Abstrak
Pajanan klorpirifos, pestitida yang umum digunakan dalam jangka waktu lama dapat meninggalkan residu pestisida di buah dan menyebabkan perubahan metabolisme tubuh. Penelitian ini bertujuan untuk menguji pengaruh pajanan klorpirifos dosis rendah dalam waktu lama terhadap kadar kolesterol total pada tikus wistar menggunakan desain penelitian kelompok kontrol acak posttest-only. Sebanyak 30 ekor tikus wistar digunakan dan dibagi menjadi lima kelompok yaitu kelompok kontrol normal (KN) dan empat kelompok yang diberi klorpirifos dosis rendah selama 7 hari (K1), 14 hari (K2), 28 hari (K3), dan 56 hari (K4). Penelitian ini dilaksanakan pada bulan Februari sampai Mei 2023. Hasil uji LSD post hoc menunjukkan perbedaan bermakna antara kelompok kontrol normal dengan kelompok pajanan K1 dan K2. Selain itu, didapatkan perbedaan bermakna antara kelompok pajanan K3 dengan kelompok pajanan K1 dan K2, serta kelompok pajanan K3 dengan kelompok pajanan K2. Disimpulkan pajanan klorpirifos dosis rendah meningkatkan kadar kolesterol total secara bermakna pada pajanan 7 hari dan 14 hari, diikuti dengan penurunan pada 28 hari dan peningkatan kembali pada 56 hari pajanan.
