Optimization of Automatic Repellent Tool to Repel Pests of Rice-Eating Birds in Takalar, South Sulawesi a) Department of Agronomy, Agrotechnology Study Program, Faculty of Agriculture, Hasanuddin University, Makassar, Indonesia Abstract Bird pests are one of the main enemies for farmers which can reduce crop production. Increasing bird populations lead to reduced yields. This is a major problem that causes the stability of rice production in Takalar, South Sulawesi to shake every year. So that one method that can be used to repel bird pests is to use an automatic bird pest repellent tool. This study aims to determine the impact of using automatic repellent to reduce the attack of rice-eating birds in Takalar. This research has an effect on a better rice cultivation process, especially in reducing the level of bird pest attacks. This research was conducted in Tonasa Village, Takalar Regency, South Sulawesi. The research implementation method includes designing a pest repellent method using an automatic air freshener machine as well as the manufacture and testing of jengkol extract vegetable pesticide liquid as a spraying agent that emits a scent that bird pests don^t like. Observation parameters used the comparison method of initial observations and final observations that were observed in the morning, afternoon and evening. The evaluation results obtained on average show quite a lot of attacks in a day, especially in the morning. After the use of the automatic repellent method, the attacks of bird groups tended to decrease where in the morning the ratio of 22 - 32 decreased to 6 - 14 attacks, while the afternoon ratio of 7 - 14 decreased to 3 - 7 attacks and the evening ratio of 20 - 29 decreased to 8 - 12 group attack of birds. So that the use of this automatic repellent has a significant and effective impact in reducing bird pest attacks.
