<![CDATA[This study examines the influence of capital and labor on the income of tuna fishermen in the Joint Business Group (KUB) Persatuan Nelayan Sukses (PNS) located in Kampung Wuring, Sikka Regency, East Nusa Tenggara. A quantitative approach was employed utilizing multiple linear regression analysis, while samples were selected through purposive sampling, resulting in 49 monthly data points drawn from the group’s operational records for the period 2020–2024. The analysis encompassed classical assumption tests—including normality, multicollinearity, heteroscedasticity, and autocorrelation—as well as partial hypothesis testing (t-test) and simultaneous hypothesis testing (F-test). The findings reveal that capital does not exert a statistically significant partial effect on fishermen’s income, whereas labor demonstrates a positive and significant partial effect. When tested simultaneously, both variables collectively exert a significant influence on income. The coefficient of determination (R²) indicates that capital and labor together account for approximately 29.8% of income variation, with the remaining 70.2% attributable to factors beyond the scope of this study. These findings underscore that improving tuna fishermen’s income requires a holistic strategy that strengthens human resources, enhances technical fishing skills, and reinforces the institutional capacity of the fishing cooperative, rather than solely relying on capital injection.]]>
