Abstrak: As the main food crop, rice plays a pivotal role on supporting physiological needs of Indonesian society as well as has high economic value. In order to increase rice yield, farmers have several obstacles to confront such as decreasing land productivity, climate change and outbreak of pest and disease. The problem of pest and diseases inflict a financial loss of farmers, therefore it needs appropriate strategyto control it in order to minimizing the damage. Integrated pest management (IPM) is a comprehensive approach to control pest and disease that had been stated in government policy and environmental friendly.

Abstrak: Elliptic curves upon F3m can be divided in two cases, i.e. supersingular and nonsupersingular case. Based on group laws on elliptic curves, a new arithmetic upon F3m can be formulated as an addition process of two random points on the curve. This addition process can then be applied to the ElGamal algorithm.
