This study is aimed to help the company doing an assembly line balancing to minimize station time as not to exceed takt time and minimize idle time between workstation, using Mixed Integer Programming (MIP) method with Multi-manned Assembly Line Balancing (MmALBP) approach using two mathematical model, which 1 st model aimed to minimize the cycle time of all workstation, then those cycle time being a parameter in 2 nd Mathematical model to specified the optimal number of workers also balancing workload between operators. Result from this research were able to minimize station time from 218.56 hour to 166.3 hour so it didn’t exceed the takt time and also could reduce total idle time until 45% from 905.2 hour in actual condition become 499.49 hour with decreased number of operator from 52 to 22 person, and increase the efficiency of assembly line from 54% in previous to 67% in the proposed line.
