Abstract: This research aims to project the development of Bali cattle population in the Timor Island pasture agroecosystem with a dynamic model for 75 years. The material used is Bali cattle (50 head of Bali cattle) with 12 months of research time from January-December 2018. Farmers and research locations were selected purposively based on criteria such as physical (land area), biology (agroecosystem) and social which generatessampling locations representing pasture located in the district of Belu, Malaka and Timor Tengah Utara. Respondents determination 5-10% of the number of farmers in theagroecosystem with the number of Bali cattle >10 cows (127 respondents). Respondents were interviewed using prepared questionnaire. In addition to interviews, field observations were also carried out. This research data uses primary data documentation. Data analysis uses a system dynamics approach with the help of powersim 2.5 software for windows. The results showed an increase in the population of Bali cattle will not reach it’s maximum point until the next 75 years if managed according to the existing conditions as applied, so far. Therefore, a strategy is needed to increase the population of Bali cattle by increasing livestock reproduction status and limiting the export/sale of Bali cattle in and out of the agroecosystem.
