Abstract

This study aims to analyze the implementation of accessibility rights fulfillment for inmates with disabilities at the Class IIA Correctional Institution in Parepare City. Persons with disabilities are a vulnerable group requiring special treatment in accordance with human rights principles and national regulations, such as Law Number 8 of 2016 concerning Persons with Disabilities and Law Number 22 of 2022 concerning Corrections. This research employs a normative-empirical method with a statutory and social approach through literature study, observation, and direct interviews with prison officials and inmates with disabilities. The results show that the Class IIA Correctional Institution in Parepare has taken significant steps to fulfill accessibility rights, such as providing special shuttle services, rooms with sitting toilets, separation of inmates with disabilities, intensive care, and wheelchair facilities. In addition, there is collaboration with the Health Office, Ministry of Social Affairs, and other agencies to support optimal services. However, there are still shortcomings, such as the unavailability of hearing aids for inmates with hearing impairments. In general, the Class IIA Correctional Institution in Parepare demonstrates a commitment to providing inclusive and non-discriminatory services, including the right to interact with other inmates. These findings highlight the importance of continuous improvement to create a disability-friendly correctional environment.

Abstract

Perkembangan teknologi informasi telah memicu transformasi berbagai bentuk kejahatan, salah satunya adalah perjudian yang kini hadir dalam format digital sebagai perjudian online. Kejahatan ini tidak hanya melanggar hukum, tetapi juga berdampak sosial dan ekonomi secara luas. Penelitian ini bertujuan untuk efektivitas efektivitas regulasi hukum di Indonesia dalam menanggulangi tindak pidana judi online sebagai bentuk kejahatan siber. Penelitian ini menggunakan pendekatan yuridis normatif dengan teknik studi kepustakaan. Data yang digunakan meliputi bahan hukum primer, sekunder, dan tersier. Analisis dilakukan secara deskriptif-analitis untuk menilai kejelasan norma, konsistensi antarregulasi, dan efektivitas penerapan hukum terhadap perjudian online. Hasil penelitian menunjukkan bahwa regulasi yang ada belum sepenuhnya memadai dalam mengatasi kompleksitas perjudian online. KUHP masih menggunakan pendekatan konvensional, sedangkan UU ITE hanya mengatur distribusi konten melakukan perjudian secara terbatas. Regulasi tambahan belum memiliki kekuatan mengikat yang cukup. Selain itu, rendahnya kapasitas aparat digital dan kurangnya koordinasi antarlembaga memperlemah efektivitas penindakan.

Abstract

Penipuan merupakan salah satu tindak pidana konvensional yang masih sering terjadi di Indonesia dengan modus yang terus berkembang, seperti investasi bodong, penipuan daring, danpenyalahgunaan kepercayaan dalam transaksi. Penelitian ini bertujuan untuk menganalisis dinamika penegakan hukum terhadap tindak pidana penipuan dalam sistem hukum pidana Indonesia, serta mengidentifikasi kendala yuridis dan non-yuridis yang dihadapi aparat penegak hukum, khususnya kepolisian, kejaksaan, dan pengadilan. Penelitian ini menggunakan pendekatan yuridis normatif yang diperkaya dengan analisis empiris melalui studi dokumentasi dan kajian kasus-kasus aktual. Hasil penelitian menunjukkan bahwa penanganan perkara penipuan masih menghadapi sejumlah persoalan krusial, antara lain kaburnya batas antara penipuan dan wanprestasi, lemahnya pembuktian unsur niat jahat, dan inkonsistensi putusan pengadilan. Selain itu, kurangnya pedoman teknis dan minimnyakoordinasi antarlembaga penegak hukum turut memperlemah efektivitas penanganan perkara. Penelitian ini merekomendasikan integrasi pendekatan hukum progresif dan restoratif dalam menangani kejahatan penipuan modern agar hukum tidak hanya represif, tetapi juga solutif dan berpihak pada korban.
