Based on Malang City Regional Regulation Number 4 of 2011 concerning Regional Spatial Planning in Malang City, regulations have been regulated regarding the existence, management, and availability of green open space in Malang City as an ecological balance in the Malang City area. However, this policy has only partially influenced green open space development, especially city parks. So currently, the Malang City government is managing and revitalizing several green open spaces (RTH) areas and city parks; even though they need to be improved, such funding problems hamper them. This research uses descriptive research with a qualitative approach. The research location was carried out at the Malang City Environmental Service. The data sources are primary data and secondary data. The data collection techniques used were observation, interviews, and documentation. For data analysis techniques in this research, we use techniques from Miles and Huberman, namely data collection, data condensation, data presentation, and data verification. The research results explain that budget problems have resulted in managing green open spaces limited to maintenance activities. This can be seen from indicators in policy implementation, which include the communication factor, namely the clarity of policy orders from the city government to the implementing organization, even though there has been no form of socialization to the public. The next factor is resources in the form of limited regional income and expenditure budgets, limiting the management of green open spaces. The third factor is good cooperation and coordination between related areas and regional apparatus organizations from within and outside the organization, such as the private sector or corporate social responsibility (CSR).Fourth, the bureaucratic structure, namely the organizational structure, the appropriate division of tasks and functions, and standard operational procedures have been implemented in green open space for the environmental service.
