The program of integrated pest control (PHT)—through the Field School of Integrated Pest Control and its various follow-up actions, was firstly introduced to Indonesia in 1989. The program is aimed at changing the paradigm of plant preservation from 'planting with pesticide' to 'planting for producing healthy plants based on the agro ecosystem analysis. It is not only the peasants' skills and knowledge that is increased in detail but also the peasant empowerment in making decision. This passage is studying the result of re-observation towards the peasants being trained in early 1990, after fifteen years went by. The pea- sants' knowledge and actions in responding to the dynamics of the nature con- dition, pest/disease attack, as well as the introduction of new ideas, reflect two characteristics of cultures. On the one hand, there is a centripetal power, i.e. the tendency of existing ideas in individuals mind in creating reproduction in the thoughts and actions. On the other hand, there is a centrifugal power, i.e. the tendency of the changing and variation in individual thoughts and actions. The passage discusses the two cultural characteristics through the effort of the peasants in some villages in Subang and Indramayu, West Java, in increasing the food production and pest control.
