Pest problems are the most frightening scourge for farmers in the process of cultivating Rojolele rice which has high rice characteristics and fragrant aroma, so it is necessary to have environmentally friendly technology assistance to assist farmers in controlling pests such as sparrows and leafhoppers. Startup Ecokarsa's solar-powered pest control technology by utilizing ultrasonic waves to make sparrows uncomfortable and ultraviolet to collect leafhoppers at one point is expected to be a solution for the Sanggar Rojolele farmer group to help control pests in the rice fields of Delanggu without damaging the environment. Because this technology is considered quite expensive for the Sanggar Rojolele farmer group, an appropriate location and allocation system is needed to determine how many points are efficient and where these points are located so that the rice fields in Delanggu are safe from attacks by sparrows and leafhoppers.
