Scheduling machine has a close relationship with the handling of the production process. One of the most important problem in production systems are not systematic handling of the production process so as not to achieve optimization. In the final project is try to discuss about the application of the method of simulated annealing for job shop scheduling at the machine factory. Input in this final project is the number of jobs, number of machines, job processing time of each machine, and machine sequence, the initial temperature, final temperature, and total iteration. Output in this final project is a job shop scheduling engine plant with a total settlement of all jobs (makespan) is minimum, as well as temperatures that meet the target
