The synchronization agenda of development planning is a crucial issue in the range of regional development processes. Synchronization mechanism is needed to ensure a planning process can be run smoothly in attempt to determine synergy of development sectors and actors.  In several regions, non-functional synchronization were consequences of unit sentiment and sectoral egoism which is not aimed to achieve a broader development goals. According to the latest theoretical study, synchronization problem can be solved by institutionalizing effective coordination and communication at all stages of development planning. This research was conducted in Blimbing sub-district, Malang City, by analyze the proposed development activities document at eleven villages in 2018. Focusing on Public Works and Spatial Planning sector proposals. The purpose of these proposals has been carefully selected and Public Works and Spatial Planning  sector was the highest preferred proposal over eleven villages. The synchronization mechanism in Blimbing Sub-district shows that it is suited with government regulation.

The research processes about synchronization generates five models of synchronization consist (a) realized development activities and funded under the proposal; (b) development activities that have been realized and funded lower than the proposal; (c) development activities realized and funded that are higher than the proposal; (d) rejected develompent proposals (e) new funded development activities although it is never proposed. Data collection of this research was collected through observation, in-depth interviews and triangulation. All data is collected using interview guide where digitally recorded and transcribed as analytical material. Otherwise secondary data is also used as an archives to study Musrenbang files in the Blimbing sub-district. Then data was analyzed qualitatively. The data analysis method used by the author is the interactive model by Miles, Huberman and Saldana. This study showed that the determining factors for successfully synchronization were largely determined by the combination of initiatives that grew from the bottom up. Among the results of synchronization that can be felt by the community, a number of programs proposed by the community can be realized, accompanied by great self-help from the community. From this research it can be used as a lesson that the synchronization process in regional development can be increased if the initiative and the spirit of synchronization can simultaneously grow between governmental and community development actors. Scheduling synchronization is an alternative strategy to improve development effectiveness.
