This book examines the impact of the cash conversion cycle on the profitability of manufacturing companies listed on the Indonesian Stock Exchange (BEI) during the period of 2010-2017. The study employs purposive sampling to select 83 companies, comprising 23 firms in the consumer goods sector, 36 firms in the primary industry and chemicals sector, and 24 firms in the miscellaneous industry. The dependent variable in this research is profitability, proxied to return on assets (ROA), while the independent variable is the cash conversion cycle. In addition, three control variables - debt, growth, and size - are considered in this study. The analysis is conducted using multiple linear regression. The findings of this research indicate that the cash conversion cycle did not have a significant effect on the profitability of manufacturing companies listed on the BEI. This book offers valuable insights into the financial performance of manufacturing companies in Indonesia, and will be useful for scholars, practitioners, and policy-makers interested in corporate finance and investment in Indonesia.
