<![CDATA[ABSTRAK Stunting masih menjadi permasalahan gizi yang membutuhkan deteksi dini dan pemantauan pertumbuhan secara berkelanjutan. Keterbatasan pencatatan dan pemantauan dapat menyebabkan informasi mengenai kondisi pertumbuhan balita belum sepenuhnya terdokumentasi. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pengetahuan dan keterampilan kader Posyandu dalam deteksi dini, pencatatan, dan pemantauan stunting melalui pemanfaatan aplikasi Gosting (Get Information of Immunization and Stunting) serta meminimalkan potensi underreporting di Desa Wonosari. Kegiatan dilaksanakan pada 14 Juli 2026 di Aula Desa Wonosari, Kecamatan Gondangrejo, Kabupaten Karanganyar, dengan melibatkan 9 kader Posyandu dan 1 bidan desa. Metode kegiatan meliputi sosialisasi, penyampaian materi, diskusi, pelatihan penggunaan aplikasi Gosting, pre-test, post-test, implementasi pendataan, serta monitoring dan evaluasi. Hasil evaluasi menunjukkan peningkatan rata-rata skor pengetahuan kader dari 4,80 pada pre-test menjadi 9,10 pada post-test. Hasil uji Wilcoxon menunjukkan nilai p = 0,004, yang menunjukkan adanya peningkatan pengetahuan kader yang signifikan setelah kegiatan. Implementasi aplikasi Gosting membantu kader melakukan deteksi dini dan pencatatan hasil pengukuran balita secara lebih sistematis. Hasil pendataan selanjutnya dibahas dalam kegiatan monitoring dan evaluasi sebagai dasar untuk mengidentifikasi balita yang memerlukan perhatian, pemantauan, dan edukasi. Pemanfaatan aplikasi Gosting diharapkan dapat dilakukan secara berkelanjutan oleh kader untuk mendukung pemantauan pertumbuhan balita, meningkatkan ketepatan sasaran edukasi, memperkuat pencatatan data, serta meminimalkan potensi underreportingdi Desa Wonosari.

Limited recording and monitoring may result in incomplete documentation of children’s growth conditions. This community service activity aimed to improve the knowledge and skills of Posyandu cadres in early detection, recording, and monitoring of stunting through the use of the Gosting application (Get Information of Immunization and Stunting) and to minimize potential underreporting in Wonosari Village. The activity was conducted on July 14, 2026, at the Wonosari Village Hall, Gondangrejo District, Karanganyar Regency, involving nine Posyandu cadres and one village midwife. The methods included socialization, material presentation, discussion, training on the use of the Gosting application, pre-test, post-test, data collection implementation, and monitoring and evaluation. The evaluation results showed an increase in the mean knowledge score from 4.80 in the pre-test to 9.10 in the post-test. The Wilcoxon test resulted in a p-value of 0.004, indicating a significant increase in cadres’ knowledge after the activity. The implementation of the Gosting application supported cadres in conducting early detection and recording children’s anthropometric measurement results more systematically. The collected data were subsequently discussed during monitoring and evaluation as a basis for identifying children requiring attention, growth monitoring, and education. The continued use of the Gosting application by cadres is expected to support child growth monitoring, improve the targeting of health education, strengthen data recording, and minimize potential underreporting in Wonosari Village.
