Abstract South Sulawesi Province has developed various innovations in poverty reduction efforts, including the utilization of data collection applications based on cross-sector collaborative action. However, implementation still faces obstacles in the target data verification and validation process, which impacts the suboptimal effectiveness of program interventions in the regions. This study aims to analyze the effectiveness of the performance of the South Sulawesi Province TKPK in coordinating the planning, implementation, and integration of poverty reduction programs across regional agencies, particularly in priority areas with high poverty rates. This research employs a qualitative approach with a case study design. Data collection was conducted through in-depth interviews, observations of the coordination process, and reviews of policy planning and implementation documentation. Data analysis used the Miles and Huberman qualitative model, which includes the stages of data reduction, data display, and conclusion drawing. The results show that the performance of the South Sulawesi Province TKPK is generally not yet fully effective. Although it has succeeded in building an innovative data collection system and identifying target groups relatively accurately, cross-sector collaboration is still hampered by data verification constraints. Major obstacles include limited operational support for data officers at the village/sub-district level, suboptimal integration of programs into regional agency budgeting documents, as well as symptoms of administrative formalism and sectoral egos between agencies. The research findings emphasize the need to strengthen coordination, synergy, and commitment among regional agencies so that poverty reduction efforts can operate in a more integrated, responsive, and sustainable manner.
