The Kebon Kongok Regional Landfill (TPA) is one of the final processing sites serving West Lombok Regency and Mataram City. The Landfill is managed by the Regional Technical Implementing Unit (UPTD) of the Regional Waste Landfill of NTB Province under the Department of Environment and Forestry of NTB Province. Currently, waste services in Mataram City and West Lombok Regency have not met the sanitation target. One of the factors that affects it is the financial problem where there is no budget flexibility which often causes difficulties in handling operations, especially at the beginning and end of the year. Therefore, the purpose of this study is to determine the institutional development strategy as an effort to increase the role of UPTD in solid waste services. The analytical method used is Force Field Analysis (FFA). Based on the FFA, it is found that the Total Weight Value (TNB) driving forces are more significant than the restraining forces; this means that UPTD of Regional Waste Landfill of NTB Province is encouraged to carry out institutional development. Therefore, the institutional development strategy is that UPTD applies for the Financial Management Pattern of Public Service Agencies (PPK-BLUD).
