Abstract

Brick light of Kalla Block is a subsidiary of PT.BUMI SARANA BETON at Kalla Group, which produces light brick of high quality raw materials with German technology that meet acceptable standards Deutch Industries Norm (DIN). Problems faced of Kalla Block this time is how to increase production ratio because increasing demand, one of the efforts is how to increase productivity and work efficiency. The purpose of this study was optimizing the number of labour based on production processes Autoclave Aerated Concrete (AAC) and assess the model in order to improve production efficiency AAC on Kalla Block company without increasing or reducing the amount of energy used is two models Workload Analysis. Model 1 according to Work Method of Load Analysis (WLA) and model 2 according to Theory Wakui (TW). The difference results workload calculation models Work Load Analysis located at Westinghouse adjustment factor and factor allowances which are based on factors such as the state of the working conditions of lighting, temperature and noise of the room. In an effort to improve production efficiency at the Kalla’s company AAC Block without increasing or reducing the amount of labour then the review in terms of time is measured by calculating the standard time. Based on research results, it is recommended to use the model 2 which obtained total value of the work load at now conditions, AAC production process is currently at 407.89% to 278.31 minutes workloading time. After the analysis of the workload and workforce optimization has gained workload with model 2 formulation of 385.49% with a time of 260.39 minutes workloading resulting workload efficiency of 22.40%.
