<![CDATA[This study aims to analyze the advocacy strategies of the Federation of Karawang Workers' Union (FSPEK-KASBI Karawang) in influencing the determination of the 2026 Regional Minimum Wage (UMK) of Karawang Regency, one of Indonesia's largest industrial districts. Using a qualitative approach with a case study design, data were collected through in-depth interviews with three key informants whose specific positions and institutional affiliations are withheld to protect their confidentiality: two informants from the labor union under study and one informant from the relevant local government agency. Data were also gathered through document analysis and observation. The theoretical framework employed is the Advocacy Coalition Framework (ACF) combined with the concept of pressure groups. The findings reveal that FSPEK-KASBI Karawang implemented a comprehensive dual-track advocacy strategy: (1) formal channels through active participation in the Regional Wage Council (Dewan Pengupahan Kabupaten/Depekab), where the union presented arguments grounded in the Decent Living Needs (Kebutuhan Hidup Layak/KHL) survey and critiqued the alpha variable formula limiting wage increases; and (2) non-formal channels through mass mobilization, public demonstrations, cross-union alliances at the Jawa Barat province level, and media campaigns. Within the ACF framework, FSPEK-KASBI Karawang operates as the core of an advocacy coalition whose belief system centers on social justice and workers' welfare, in contrast to the employer coalition (APINDO) whose belief system emphasizes economic efficiency and business continuity. The government, represented by Disnakertrans, acted as a policy broker facilitating dialogue and compromise between the competing coalitions. The 2026 UMK was ultimately set at Rp5,886,853 (a 5.13% increase), reflecting a negotiated compromise among the contending interests. Historical evidence suggests that the relatively high UMK in Karawang compared to other regions is partly attributable to the strong tradition of mass mobilization by labor unions. This research contributes to understanding of labor union advocacy dynamics at the local level within Indonesia's post-Omnibus Law regulatory environment and recommends strengthening inclusive, transparent social dialogue mechanisms in regional wage-setting processes.]]>
