Abstract
Cashew and pepper are kind of important commodity in Indonesia. In recent times, productivity of these plants decreased due to insect pest Helopeltis antonii and Dacinus piperis. Generally, farmers use synthetic insecticide to control these pests. The use of synthetic insecticide gives risk to human and environmental. Therefore, there is an urgent need to find natural insecticide to control cashew and pepper insect pest. Many researches showed that buah makasar (Brucea javanica) contains quassinoid compounds having insecticidal activities against several pests (Subeki et al., 2006; Latif et al, 2000; Daido et al., 1995; and Klocke et al., 1985). In this research was carried out extraction and isolation of brucein-C from B. javanica and assayed its activity against H. antonii and D. piperis. Result of this research showed that bruceine-C formulated with liposomes at concentration 200 ppm gave mortality of H. antonii and D. piperis with value of 98.3% and 91.7%, respectively. Residual contents of bruceine-C in the soil on the fifteenth and thirtieth day after application at concentration 200 ppm decreased to 80 ppm and 0 ppm, respectively. Application of bruceine-C has no lethal effect against non target insects. Hypothetical study on the technoeconomy showed that insecticide with active substance brucein-C have price 40,3% cheaper than synthetic insecticides. This research can be recommended to Indonesian government to produce natural insecticide from the original Indonesian plant buah makasar.
