Poverty is a serious problem faced by many developing countries, including Indonesia. This study aims to investigate the role played by social capital in achieving the success of the Joint Business Group (KUBE) program in Semper Timur Village, North Jakarta. To overcome this problem, the joint venture group program was implemented in North Jakarta by Jakarta Entrepreneurship. This study used a qualitative approach by conducting in-depth interviews and observing the Rizki Berkah joint venture group in North Jakarta. The research results show that social capital plays a vital role in achieving the success of joint venture groups in overcoming poverty. Trust, social networks, access to information, and support from group members are important elements in facilitating collaboration, exchanging knowledge and skills, and access to resources needed for business. Joint venture groups with high social capital tend to be more successful in facing challenges, taking advantage of opportunities, and achieving success in their businesses. Active involvement in social networks, strong trust between group members, and solid cooperation are important factors in building strong social capital. In addition, the joint business group program also provides support in the form of facilities and infrastructure, skills training, mentoring, and access to capital. The availability of these facilities provides additional impetus for joint venture groups to achieve success. This research makes an important contribution to understanding the role of social capital in joint business group programs. These findings can form the basis for developing policies and strategies more effectively alleviate poverty in North Jakarta and other parts of Indonesia.
