Data profil kesehatan pegawai tahun 2024 menunjukkan 55,65% pekerja mengalami berat badan berlebih, 9,54% berisiko sindrom metabolik, serta peningkatan prevalensi hipertensi. Sebagai tindak lanjut, perusahaan telah menjalankan program wellness, namun partisipasi pekerja masih rendah, hanya 7,1%, menunjukkan program belum berjalan optimal dan evaluasi menyeluruh belum dilakukan. Penelitian ini bertujuan mengevaluasi pelaksanaan program wellness pada pekerja PT. X tahun 2025 menggunakan model evaluasi CIPP (Context, Input, Process, Product) dengan metode kualitatif dan desain studi kasus. Data dikumpulkan melalui wawancara mendalam dan telaah dokumen terhadap informan yang dipilih secara purposive dan snowball sampling. Hasil penelitian menunjukkan, pada aspek context, tujuan program telah sesuai kebutuhan kesehatan pekerja namun belum dipahami merata. Aspek input menunjukkan keterbatasan sumber daya manusia, ketimpangan sarana prasarana, keterlambatan pembayaran vendor, serta belum adanya pedoman teknis khusus. Pada aspek process, program belum didukung needs assessment sistematis, komunikasi dan dukungan pimpinan terbatas, dan program belum menjadi indikator kinerja. Aspek product menunjukkan partisipasi dan konsistensi peserta rendah, meski ada dampak positif terhadap perilaku dan kesehatan fisik serta mental pekerja. Perusahaan disarankan melakukan survei kebutuhan, menyusun pedoman teknis, menyederhanakan program, mengoptimalkan komunikasi internal, memperkuat dukungan pimpinan, mengintegrasikan OKR, menyusun strategi fasilitas, dan menyampaikan evaluasi ke manajemen untuk meningkatkan partisipasi pekerja.Employee health profile in 2024 shows that 55.65% of workers are overweight, 9.54% are at risk of metabolic syndrome, and there is an increasing prevalence of hypertension. As a follow-up, the company has implemented a wellness program; however, employee participation remains low at only 7.1%, indicating that the program has not yet run optimally and a comprehensive evaluation has not been conducted. This study aims to evaluate the implementation of the wellness program for PT. X employees in 2025 using the CIPP evaluation model (Context, Input, Process, Product) with a qualitative case study design. Data were collected through in-depth interviews and document reviews with informants selected via purposive and snowball sampling. Results show that, in the context aspect, the program’s objectives align with employees’ health needs but are not yet widely understood. The input aspect reveals limitations in human resources, uneven facilities, delayed vendor payments, and the absence of specific technical guidelines. In the process aspect, the program lacks a systematic needs assessment, leadership communication and support are limited, and the program is not yet linked to performance indicators. The product aspect shows low participation and consistency, although there are positive effects on employee behavior, physical health, and mental health. The company is advised to conduct a needs survey, prepare technical guidelines, simplify the program, optimize internal communication, strengthen leadership support, integrate OKRs, develop facility strategies, and report evaluations to management for program participation improvement.
