Foto Degradasi Pestisida Berbahan Aktif Klorpirifos Di Tanah Ultisol

---

ABSTRACT
Ultisol soils are widely found in Indonesia and possess chemical and physical properties that can influence the photodegradation process. Chlorpyrifos, as one of the most commonly used pesticides, tends to persist in the soil, posing a risk of environmental contamination. Photodegradation, which involves the breakdown of chlorpyrifos under sunlight, is an effective method to accelerate the reduction of chlorpyrifos residues in soil and minimize its negative environmental impacts. This study aimed to reduce chlorpyrifos levels in ultisol soils through photodegradation and to evaluate the effectiveness and influencing factors of this process. The experiment was conducted using a factorial completely randomized design with two factors: sunlight exposure (direct and indirect) and exposure duration (0, 7, 14, 21, and 30 days). Parameters observed included chlorpyrifos concentration, degradation rate, and half-life. The results showed that direct sunlight significantly accelerated chlorpyrifos degradation compared to indirect exposure. Longer exposure times led to greater reductions in chlorpyrifos levels. The degradation rate under direct sunlight (k = 0.107) days-1 was higher, with a shorter half-life (t½ = 6.476 days), compared to indirect sunlight (k = 0.098 days-1; t½ = 7.071 days). These findings indicate that direct sunlight exposure enhances chlorpyrifos degradation, making it more readily decomposed in ultisol soils. Further field-scale studies are recommended to better represent actual environmental conditions.
