Abstract

Stunting is a chronic nutritional problem that remains a major public health issue in Indonesia. This study aims to develop a classification model for stunting risk in children using a combination of hybrid feature selection and ensemble learning methods. The dataset used is derived from socio-economic and health data obtained from the Central Statistics Agency and open datasets. The research method includes data preprocessing, feature selection, model development using Random Forest and Gradient Boosting combined with a Voting Classifier, and evaluation using accuracy, precision, recall, F1-score, and ROC-AUC metrics. The results show that the proposed model achieves high performance with accuracy reaching 98% and ROC-AUC close to 1. The hybrid feature selection successfully improves model efficiency by selecting relevant features. This study demonstrates that the integration of feature selection and ensemble learning can produce an accurate and interpretable model for early detection of stunting risk.

Abstract

The development of digital transformation in the field of education encourages schools to adopt technology that can improve the effectiveness of academic administration, particularly in the student attendance system. SMK PAB 8 Sampali Medan still faces several problems in the conventional attendance process such as delays in recording, potential manipulation of attendance, and suboptimal monitoring of student attendance data. This community service activity aims to implement a Smart Attendance System based on RFID and Face Recognition to improve the efficiency, accuracy, and security of the student attendance process. The implementation of the activity is carried out through stages of observing the school's needs, system design, installation of RFID devices and face recognition cameras, training teachers and school operators in using the system, and assistance in implementation. The results of the activity show that the implemented system is capable of accelerating the student attendance process in real-time, minimizing recording errors, improving student attendance discipline, and facilitating the school in monitoring and digitally summarizing attendance data. In addition, this activity also improves technology literacy for teachers and administrative staff in supporting the digital transformation of education within the school environment.

Abstract

Pembelajaran mendalam berbasis STEAM merupakan pendekatan pembelajaran yang diterapkan dalam Kurikulum Pendidikan Nasional saat ini untuk meningkatkan kemampuan numerasi siswa. Namun, penerapan pembelajaran mendalam berbasis STEAM belum optimal dilakukan karena belum didukung oleh teknologi yang memfasilitasi kebutuhan numerasi siswa. Kemampuan numerasi siswa sangat bergantung dengan kompetensi numerasi guru. Solusi dari masalah tersebut adalah dengan menerapkan pembelajaran mendalam berbasis STEAM terintegrasi 3D-printing yang dapat meningkatkan kompetensi numerasi guru. Mitra kegiatan adalah komunitas belajar guru yang terdiri dari 30 orang guru di SMP Negeri 14 Binjai. Kegiatan dilakukan dengan menggunakan metode partisipatif, yang terdiri dari tiga tahapan, yakni persiapan, pelaksanaan, dan evaluasi serta refleksi. Hasil evaluasi yang dilakukan melalui pemberian pre-test dan post-test menunjukkan peningkatan pemahaman yang signifikan, di mana sebanyak 86,7% guru berhasil mencapai kategori cukup dan baik setelah program dilaksanakan, dibandingkan kondisi awal yang mayoritas berada pada kategori rendah dan sedang. Program ini juga menghasilkan luaran berupa modul pelatihan, rancangan pembelajaran numerasi terintegrasi 3D-printing, serta terbentuknya komunitas belajar guru sebagai wadah kolaborasi berkelanjutan
