<![CDATA[Coastal communities in Biluhu Village face fluctuating income due to limited marine resource utilization and coastal ecosystem degradation. This study aims to analyze the effect of marine resource utilization and environmental awareness on fishermen's income in Biluhu Village, Batudaa Pantai District. A quantitative associative approach was employed with a population of 204 fishermen, from which a sample of 61 respondents was selected using purposive sampling. Data were collected via structured questionnaires and analyzed using multiple linear regression in SPSS software. The results indicated that marine resource utilization had a positive and significant effect on fishermen's income (t=11.863; p=0.000). Environmental awareness also had a positive and significant effect (t=11.778; p=0.000). Simultaneously, both variables had a significant influence (F=181.879; p=0.000) with a coefficient of determination (R^2) of 0.862. The regression equation was Y=10.039+0.301X_1+0.321X_2. These findings confirm that improving coastal fishermen's economic income depends significantly on optimizing marine resource utilization and reinforcing environmental sustainability behaviors.
