Pdirect effect test found that capital has no effect on product innovation by -0.035, P-Value 0.754 (Not supported H1).

Capital has a significant effect on the competitiveness of SMEs by 0.220, p-vale 0.014 (Supported H3). Empowerment has a significant effect on MSME competitiveness by 0.542, and p-value 0.000 (Supported H4), and product innovation has a significant effect on MSME competitiveness by 0.274 and p-value 0.000 (supported H5). To test the indirect effect using the Sobel test calculator, it was found that product innovation variables were able to partially mediate the relationship between capital and empowerment on the competitiveness of SMEs.
