Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk menggambarakan evaluasi pelaksanaan program pencegahan dan penangan wasting pada balita di Jakarta Selatan tahun 2024. Beberapa upaya dan program telah dilaksanakan di Jakarta Selatan, evaluasi program tersebut dilakukan melalui analisis input, proses, output, dan outcome. Informan penelitian terdiri dari penanggungjawab program gizi Dinas DKI Jakarta, Suku Dinas Kesehatan Jakarta Selatan, Puskesmas Kecamatan Jagakarsa, Tebet, Setiabudi, Mampang Prapatan, dan Pesanggrahan, serta ibu balita wasting yang menjadi peserta program. Pengambilan data melaui wawancara mendalam, diskusi kelompok, serta telaah dokumen. Hasil penelitian menunjukkan terdapat beberapa evaluasi program seperti sistem e-ppgbm yang sering error, dana APBD yang perlu pencairan tepat waktu, jumlah tenaga gizi yang terbatas, masih perlunya pelatihan terkait dengan komunikasi persuasif kepada tenaga gizi, penjagaan mutu PMT dari penyedia/catering, serta penguatan kolaborasi lintas sektor. Setelah menerima intervensi, balita mengalami kenaikan berat badan, sebagian balita juga mengalami perubahan status gizi, namun dapat mengalami penurunan berat badan kembali. Oleh karena itu, output dari program belum signifikan. Perlu perbaikan dari program wasting yang telah dilaksanakan di Jakarta Selatan untuk meningkatkan kualitas.

Several efforts and programs have been implemented in South Jakarta, the program evaluation was conducted through input, process, output, and outcome analysis. The research informants consisted of the person in charge of the nutrition program of the DKI Jakarta Agency, the South Jakarta Health Sub-Department, the Community Health Centers of Jagakarsa, Tebet, Setiabudi, Mampang Prapatan, and Pesanggrahan Districts, as well as mothers of wasting toddlers who were program participants. Data collection was through in-depth interviews, group discussions, and document reviews. The results of the study showed several program evaluations such as the e-PPGBM system that often had errors, APBD funds that needed to be disbursed on time, the limited number of nutrition workers, the need for training related to persuasive communication to nutrition workers, maintaining the quality of PMT from providers/catering, and strengthening cross-sector collaboration. After receiving the intervention, toddlers experienced weight gain, some toddlers also experienced changes in nutritional status, but could experience weight loss again. Therefore, the output of the program was not yet significant. Improvements are needed to the wasting program that has been implemented in South Jakarta to improve quality.
