Good financial management has a central role in business, involving managing funds effectively and efficiently to maximize profits and company value by managing financial risks. Profitability ratios, especially Return on Equity (ROA), are the main indicators in measuring a company's ability to generate profits. Optimizing operational costs is a key strategy in increasing profitability. This research focuses on PT MSAL, an oil palm plantation company that is trying to increase profitability through optimizing operational costs. A quantitative approach with simple linear regression analysis was used as the research method. Secondary data in the form of financial reports for the last three years (2020-2022) as research objects. The results of the analysis between operational costs and company profitability prove that there is a positive and significant influence. The partial hypothesis test shows that operational costs have a statistically significant impact on profitability. Simple linear regression analysis produces a regression line equation, and the coefficient of determination shows that operational costs have a contribution of 99.4% to the company's profitability. Operational costs have an important role in determining PT MSAL's level of profitability. Optimizing operational costs can improve a company's financial performance. Therefore, companies are advised to continue to evaluate, develop efficient business strategies, and regularly monitor the relationship between operational costs and profitability.

Technological developments continue to increase not only in the industrial sector, but have also spread to the agricultural sector, including the tomato farming process. Currently, the stage of harvesting tomatoes no longer relies on manual work, but instead utilizes artificial intelligence technology based on images preprocessing. This research aims to see whether the independent variable (AI effectiveness) has an influence on the dependent variable (tomato ripeness level). The method used is qualitative with simple linear regression data analysis techniques which include the t test and f test. The sample used was a random sampling technique with data collection by distributing questionnaires to a total of 48 respondents. The research results show that the effectiveness of AI has a positive effect on the level of ripeness of tomato fruit. This can be proven from a simple linear regression analysis to obtain the equation Y = 3.498 + 0.787X. The findings from the ttest show that tcount (7.644) > ttable (2.012) with a significance of 0.001 < 0.05. Therefore, the conclusion drawn is to accept the alternative hypothesis (H1) while rejecting the null hypothesis (H0).
