Abstrak Quality is an important factor in a company, both in product and service produced. Considering the quality problem, the final project research was taken place in PT. Djitoe Indonesian Tobacco Coy in production division of tangan hijau cigarette. The research aims to find out the defects level of product based on the p chart as well as to identify the factor causing the product defect. This study was done using observation and direct interview with the concerned personnel, recording data required and literary study or collecting data from the article, reference and other information sources relevant to the research. In addition, the method of analysis to find out the product defect level was also used, that is, by using p chart, developing pareto chart as well as developing the causal chart to find out the cause of product damage. The data obtained from the research conducted in PT. Djitoe Indonesian Tobacco Coy was the data on production of 2008 and data on production defect type of 2008. From the analysis on p chart, it can be found that the means proportion of defect (CL) is 0.003405, upper control limit (UCL) is 0.003495243 and lower control limit (LCL) 0.003314757, besides, it can also be found the defect proportion exceeding control limit. The defect proportion exceeding control limit occurs in January, July, September and October. The sufficiently significant product damage occurs in July due to the many folding and cutting employees absent, so that many employees with good performance should roll and cut the cigarette more than usual. Such condition makes the employees exhaustion so that many products are damaged. To describe the frequency of defects occurring, the pareto chart analysis was used. With this chart, the sequence of product defect type can be found from the largest to the smallest. Analysis on causal chart was used to find out the cause of product damage. The analysis on causal chart identifies the factors causing the product damage including equipment, material/raw material, environment, work method and human resource factors. Considering the analyses conducted, it can be concluded that the product damage results from many factors: equipment, material/raw material, environment, work method and human resource. Those factors lead to the proportion of product damage exceeding the control limit. Those problem can be coped with by repairing the factors resulting in the product damage, so that the product damage can be minimized.
