**4. Performance indicators and role of stakeholders in river basin management**

Stakeholder collaboration and synergy are needed in river basin management to maintain the formalization and implementation of activities or programs that manipulate natural and human resources found in river basins to obtain production and service benefits without causing damage to water and soil resources. It is important to manage and allocate natural resources for river basins, including prevention of flooding and erosion, as well as protection of the aesthetic value associated with natural resources. River basin management should include strategies for identifying linkages between land use, land and water, and linkages between upstream and downstream areas of a river basin. River basin management needs to consider the social, economic, cultural, and institutional aspects operating within and outside the river basin concerned.

Ecosystems must be viewed holistically, namely by identifying the key components that make up the ecosystem and examining the interactions between these components. A holistic approach is carried out so that the utilization and conservation of natural resources can be carried out efficiently and effectively, which is a requirement for the realization of the use of natural resources for sustainable development. River basin management is one of the government's authorities that can be decentralized based on authority and function. The form can refer to the division model, namely deconcentration, delegation to parastatal or semi-autonomous organizations, devolution, privatization, or transfer of affairs from the government to non-governmental institutions [19]. Successful intergroup performance is a function of a number of factors. The broader concept (umbrella concept) that overrides these factors is that the coordination of each of the following factors can affect coordination efforts.

To achieve sustainable river basin development, economic development activities and environmental protection must be harmonized. In this case, it is necessary to unify the two perspectives realistically by adjusting river basin management activities and conservation of upstream areas into economic and social realities. Therefore, it is necessary to know the respective roles of the parties who will collaborate in river basin management, and it is necessary to know how to identify performance indicators.

Stakeholders have the authority and responsibility in terms of managing natural resources around the river basin. Stakeholders are expected to contribute directly or indirectly to river basin management. There are five measurement indicators obtained based on the results of interviews and assessment of the performance scores of activities carried out by various stakeholders, namely:

a.Policy Determination: The role of Stakeholders has a policy in determining the target of activities in the river basin ranging from central policies to regional policies. This policy determines the sustainability of the criteria in river basin management.
