Present Development planning in flood and rob (coastal floods) coping emphasizes collaboration, because the problems are too complex. It is very important to combine all of the stakeholder's resources for achieving common goals. Floods and rob have become a chronic problem for Pekalongan City, especially in Panjang Baru Village. Various treatments up to now have not been able to overcome the main problems and their emerged impacts. The coping by various stakeholders are still partial and oriented in an emergency situation. Institutional collaboration between all stakeholders is needed to maximize all resources. To reach the collaboration stage, it is necessary to measure the extent of the level and to find out how the collaboration map has been achieved by all stakeholders involved. Collaboration levels and maps can provide an overview of information about current collaboration achievements. The achievements understanding of existing collaborations can be used as an evaluation in reaching the collaboration stage. Quantitative method is used in this study, to measure the achievement level of collaboration using level of collaboration scale. This measurement also presented a map of collaboration among involved stakeholders. The measurement results obtained by the average value of collaboration are still low, not even reaching the level of coordination. The highest rating and anomalies from the values obtained are discussed in this study. Finally, the results of this study are expected to be an input and consideration for all stakeholders in overcoming flood and rob problems in Pekalongan City, especially in Panjang Baru Village.
