The survival of a network organization as a policy implementer depends on the exchange of resources between network actors. Various studies have explained this exchange process, but in this study, was identified as a strategy to improve the performance of the policy. The main objective of this study is to explain the network exchange mechanism as a strategy for the implementation of the food diversification policy in Indonesia. The research method used a qualitative approach and a case study strategy to explain the exchange strategy for the food diversification policy. Data collection used is in-depth interviews and documentation. Data processing and analysis involve data reduction, presentation, and concluding. The results showed that the implementation of food diversification policies was not yet effective. This is caused by the exchange mechanism as a strategy has not been effective either. This is indicated by the exchange conditions of network actors, in the form of demand uncertainty, task complexity, asset specificity, and frequency that have not supported the effective implementation of this policy. The same social mechanisms in the form of restricted access, macro culture, collective sanctions, and reputation have not facilitated the successful implementation of this policy.

Trust that is well built in the policy-making process in network organizations gives birth to an effective policy outcome in the form of decreased assumption levels. This research method uses a qualitative approach and a case study strategy to explain trust in the implementation of food diversification policies. The data was collected through in-depth interviews and observations. Data processing and analysis techniques are carried out in three stages, namely: data reduction, presentation and conclusion drawing. The informants in this study were as follows: a) Chair of the Women Farmers Group b). sub-district extension team; d) District extension team.The results showed that the trust that occurred in the interaction of actors, in this case the Food Security Service, Extension Officers and the Women Farmers Group in the implementation of food diversification policies in Bone Regency was not effective. This can be shown that there is no mutual agreement that can be used as a rule of the game for the actors involved in implementing this policy. Opportunistic behavior is a sub-concept that assesses the presence and absence of trust, which is not identified in this study, because there is no mutually agreed upon rule of the game. Then, the actors' good will trust does not emerge because they are still designing and running their respective programs. Therefore, the implementation of the diversification policy requires trust between them so that the performance of this policy can be realized.
