Abstract
The export demand for Electoric Control Unit (ECU) products, which continued to increase by approximately 25% in December 2014, made the company have to review its production capacity. Based on current production capacity data, it is known that the process cycle time is 64.9 seconds while the takt time needed to meet consumer demand is 39.4 seconds for the first production line. With working time included in working hours overtime, this first-line capacity cannot meet production demands. Work measurement is done to get actual time data for capacity calculation. Man machine chart is one of the tools used to determine the production line capacity with the current number of machines and workers. To be able to fulfill the production demand, a capacity design with 2 proposed improvements is carried out, namely: adding a working time of one shift for the first production line or balancing work time between lines. By calculating the results obtained and the costs incurred, the proposal for balancing work time between lines becomes more effective to do.

Dengan perhitungan dengan biaya pekerja kontrak per tahun sebesar Rp. 45.760.000, maka biaya pekerja kontrak per bulan dapat dihitung dengan membagi biaya pekerja per tahun dengan 12 bulan

Summary
Jika jam kerja yang dibutuhkan melebihi dari jam kerja tersedia, maka perusahaan tidak dapat memenuhi permintaan produksi dari konsumen. Dari hasil observasi awal dikethaui bahwa lini perakitan pertama memiliki cycle time proses sebesar [64,9] detik sedangkan Takt time yang diperlukan untuk memenuhi permintaan konsumen adalah sebesar [39,4] detik untuk produk ekspor. Dengan cycle time yang lebih besar dari Takt time maka dapat dikatakan bahwa kapasitas lini produksi tidak dapat memenuhi permintaan produksi dengan menggunakan jam kerja normal. Tujuan penelitian ini adalah mengetahui bagaimana kapasitas lini pertama saat ini dan melakukan perancangan kapasitas produksi untuk memenuhi permintaan konsumen jika diperlukan. Akan dilakukan penelitian menggunakan man-machine chart untuk mengetahui keseimbangan antara mesin dan pekerja sehingga diketahui kapasitas produksi saat ini. Maka dilakukan perancangan kapasitas produksi untuk dapat memenuhi permintaan produksi yang meningkat di bulan Desember 2014
