Forest management in an integrated production is to obtain an optimal result by considering policies for sustainable harvesting of forests can be maintained. In the application of Linear Algebra 1, forest management that is based on a policy by considering the sustainability of forest harvesting is harvesting model that can be justified. This model set the initial configuration of the forest must be equal to the final configuration after deducting harvesting and forest plus the new seedlings. Initial configuration consists of forest plants with different age groups in early growth, while the final configuration consisted of forest plantations in the age group that remains after a period of growth.
Mathematically by letting a non-harvest vector x, the matrix will be obtained by non-harvest growth of vector Gx, and letting the harvest vector y, obtained by matrix Ry seedling crop replacement vector must equal the non-crops vector x in the beginning of growth, thus Gx – y + Rx = x. Optimal results can be cultivated is determining 
with i is the age group, is the economic value of pine on the i group, and Yi is a lot of his pine is harvested at the i group.
This research aims to (1) discusses the basic theory of forest management with harvesting model that can be justified, (2) defines the parameters associated with the management of pine forests and determine the optimal solution in a pine forest overlapping, and (3) interpret the results of mathematical models obtained into the pine forest management issues
The data obtained were used to determine the matrix of pine forest growth in order to get the initial configuration of the forest. Also taking into account the economic value of pine and a lot of pine in a forest can be determined which age groups should be harvested with the results of the optimal forest production.
Those were some example of algebra 1 help and algebra 1 answer in terms of optimizing the production using mathematics function, specifically algebra 2.
