The results of the community service activity show positive outcomes. It indicates that there is an average increase of 27 points in written test scores before and after the community service. This demonstrates that participants in the community service have improved their knowledge and skills in effective and efficient family financial management systems.

In conclusion, community service on effective and efficient family financial management systems has been successfully conducted for 35 Indonesian workers working in Malaysia.
