    abstract = {The purpose of the research was to analyze the
development of beef cattle population in Timor Island in
supporting the role of Nusa Tenggara Timur as a beef
cattle production area in fulfilling national meat needs.
This research was conducted for 1 year, starting in
January-December 2019 with the approach of
agroecosystem location by purposive sampling based on
physical criteria (land area), biology (availability and
population of beef cattle) and socio-culture, so that, the
sampling locations representing forest agroecosystems in
Timor Tengah Selatan district. The material used was 136
beef cattle in the age range of 3-4 years involving 102
respondents beef cattle farmers. Respondents were
interviewed using prepared questionnaires. In addition, field observations were carried out to determine the
physiological status of beef cattle. This research uses
primary and secondary data. Data analysis is done by
building a dynamic system using Powersim and
interpreting simulation results for the next 30 years. The
results showed the role of Timor Island as an area of
beef cattle production centers in supporting government
policies to fulfill national meat needs to be considered in
the aspect of beef cattle export from the province of Nusa
Tenggara Timur because it would be problematic in
aspects of beef cattle population on Timor Island. This is
influenced by factors of calf mortality and brood stock
mortality that are still high, low reproductive status of
livestock and export of beef cattle that have not
considered the ability of the region. Based on the results
of dynamic system analysis shows that the government
needs to reduce livestock quota according to the ability of
agroecosystems to prevent the decrease in cattle
population.}
