Abstract
Spodoptera frugiperda is a new type of pest that was first discovered in several countries in the Americas and has spread to several other countries in the African region detriment agricultural production which is caused by pests S.frugiperda in the year 2018 ranged between 4 million tons - 18 million tons every year. This loss is equal to Rp. 64,561,000,000 per year. In addition to plant pests, agricultural waste is also a major problem in the agricultural sector. One of the agricultural wastes is cocoa peels. Cocoa pod peels waste can reach 74% or equivalent to 2,4 million tons/ year. Cocoa peels contain secondary metabolites derived alkaloid purine namely santin and theobromine (metilsantin), flavonoids, pectin, tannins, saponins, and triterpenoids which serves as a repellent (reppelent), an inhibitor of eating (antifeeding), and is poisonous (toxic) for insects. The purpose of this study was to determine the level of effectiveness of using cocoa pod waste extract in controlling S. frugiperda pests. This research method used Completely Randomized Design (CRD) with control treatment, cocoa peels extract 1%, 0.75%, 0.5%, 0.25%, and 0.15%. The results showed that the cocoa pod peels extract had a significant effect on the mortality of S. frugiperda larvae. The concentration most effectively shutting S.frugiperda is a concentration of 1% with an average percentage of the highest mortality is 87.8%. The results of the probit analysis to determine the LC50 value also showed an effective concentration level to kill insects as much as 50%, namely 1%.
