- ABSTRACT The pests on chilli plantations area serious issue in considering to chillies. Pest can cause a serious failure to the chilli crop, therefore planting chillies is closely related to a high cost. The next action, the chilli farmers treat pests with excessive use of pesticides. Currently,a widely sold and used pesticide by chilli farmers in the field is a pesticide that has chlorpyrifos as its active ingredients. There are at least 40 brands of pesticides made from chlorpyrifos, and 8-10 of them are used by chilli farmers. The aim of research is to evaluate of chlorpyrifos residues remediation chilli planting soil with different textures. The research has been conducted at the greenhouse of the Agricultural Environment Research Institute (IAERI) during July-November 2017. The experiment was carried out in potswith soil media from Magelang (light texture) and Pati (heavy texture). The study used randomized block design with 3 replications, 2 factors and 5 treatments (10 treatment combinations). The two factors are soil texture, namely: (T1 = light texture and T2 = heavy texture). Meanwhile, the five treatments are: (P1) urea coated with activated charcoal; (P2) urea coated with activated charcoal enriched with microbial consortia; (P3) urea coated with biochar; (P4) urea coated with biochar enriched with microbial consortia; (P5) farmers methods (150 kg/ha urea). The results showed that urea coated with biochar and urea coated with biochar enriched with microbial consortia effectively reduced the chlorpyrifos residue both in light textured soil from Magelang and heavy textured soil from Pati. The clay content in heavy textured soil from Pati increases the degradation process of chlorpyrifos in the soil. The results of chilli plant successively from the highest are urea coated with activated charcoal enriched with microbial consortia > urea coated with charcoal > urea coated with activated charcoal > urea coated with biochar enriched with microbial consortia > farmers methods (in light textured soil from Magelang). While urea coated by activated charcoal>urea coated by biochar enriched with microbial consortia > urea coated with activated charcoal enriched with microbial consortia > farmers methods > urea coated with biochar(in heavy textured soil from Pati).
