Indonesian law reform faces persistent challenges stemming from fragmented human resource capacity, which undermines the coherence and effectiveness of justice delivery. This study critically examines the interplay between human resource development and the success of legal reform in Indonesia, emphasizing the urgent need to address systemic inefficiencies and skill gaps. As globalization and complex socio-legal issues demand more sophisticated legal systems, the pressure on Indonesia’s legal institutions to enhance their human resource capabilities has intensified. The novelty of this research lies in its focused analysis of human resource capacity as a critical yet underexplored dimension of Indonesian law reform. By employing a socio-legal methodology, the study identifies key factors contributing to fragmentation, including uneven competency levels, inadequate training, and lack of coordination among legal institutions. It further evaluates the role of education, professional development, and policy frameworks in fostering a coherent and competent legal workforce. The findings demonstrate that a robust, well-coordinated human resource strategy is essential for advancing legal reforms and delivering justice effectively. This research contributes to the discourse by proposing actionable solutions, including curriculum reforms, capacity-building initiatives, and collaborative networks among legal practitioners, academics, and policymakers. By addressing the critical gap in human resource capacity, this study provides a pathway for achieving a coherent legal system that upholds justice and aligns with Indonesia’s broader development goals.

Kekurangan gizi menjadi masalah dalam tumbuh kembang anak yang dapat menyebabkan stunting, wasting, mudah terkena penyakit serta penurunan kecerdasan otak dan mental. Stunting di Kabupaten Sikka pada tahun 2022 sebesar 13,8% dari hasil e-PPGBM periode Bulan Agustus 2022. Untuk mengatasi masalah ini diperlukan klasifikasi status stunting yang sangat berpengaruh terhadap tumbuh kembang anak sehingga dapat memberikan perhatian lebih dari faktor stunting yang paling tinggi di suatu daerah. Dengan bertambahnya jumlah balita dan peningkatan kasus stunting, proses penyelesaian tidak bisa dilakukan dengan cepat. Selain itu, tidak semua petugas posyandu bisa menghitung status gizi balita secara manual. Oleh karena itu, agar orang tua dan kader posyandu dapat mengetahui kondisi anak lebih cepat, diperlukan sistem yang menggunakan model algoritma C4.5. Sistem ini mampu mengolah data numerik (kontinu) dan diskrit. Penelitian ini menggunakan 5 atribut, yaitu usia, inisiasi menyusui dini (Imd), tinggi badan, jenis kelamin, dan berat badan. Keistimewaan penelitian ini adalah penggunaan atribut Inisiasi Menyusui Dini (IMD) yang belum pernah digunakan dalam penelitian sebelumnya dengan data numerik. Penggunaan algoritma C4.5 untuk menganalisis hasil stunting dan menyajikannya dalam bentuk website menghasilkan tingkat akurasi yang tidak jauh berbeda dengan pembagian data latih dan data uji sebesar 92.68 dan 90.98% dengan Max Dept 10.
