In 2022 exports of plantation companies will experience a significant decline in exports, especially in exports of palm oil and rubber. According to GAPKI, exports of palm oil decreased by 0.4%. And according to GAPKINDO stated that rubber exports decreased by 13.03%. This causes inflation in Indonesia and increases the risk of bankruptcy for companies. This study aims to determine whether there is an effect of profitability and firm size on capital structure. The independent variables studied were Profitability (X1) and Firm Size (X2). The independent variable in this study used Capital Structure (Y). This type of research belongs to the type of exploratory descriptive research, using a case study research method with a quantitative approach. The results of the study stated that partially profitability has a negative effect on capital structure, firm size has no effect on capital structure. Simultaneously the profitability and firm size variables together influence the capital structure. The correlation test states that there is a close relationship between the Profitability variable (X1) and the Firm Size variable (X2) on Capital Structure (Y) with an R2 value of 0.764, which means that this research has the model ability to explain the dependent variables of 76, 4% while 0.246% is explained by other variables not discussed in this study.
