Abstract

This research aims to identify: first, the urgency of reconstructing the design of reviewing the regional regulations after the Constitutional Court decision, and second, reviewing the regional regulations which are in line with the system of regional government administration and the system of reviewing legislative regulations in Indonesia. This is a juridical-normative research. The results of the research conclude that: first, the urgency of reconstructing the review of regional regulations after the Constitutional Court decision is based on: a) the central government has lost control and correction of regional regulations; b) the problematic design of reviewing the regional regulations at the Supreme Court; and c) institutional problems of the Supreme Court in reviewing regional regulations. Second, the design of reviewing the regional regulations and the proposed regional legislation reviewing system, among others: a) expanding the clarification authority of the central government by canceling/revoking regional regulations whose content regulates the implementation of assistance tasks and/or regulates further elaboration of legal regulations -higher invitation by the central government/governor as a representative of the central government; and b) redesign of the Supreme Court's procedural law in reviewing statutory regulations by accommodating formal review; changing the concept of respondent to parties which include the applicant, the person providing information, and related parties; holding trials open to the public, forming a field (panel of judges) for reviewing statutory regulations; and extending the deadline for completing statutory examinations.Keywords: testing, regional regulations, Supreme Court, and Constitutional Court. AbstrakPenelitian ini bertujuan untuk mengetahui: pertama, urgensi rekonstruksi desain pengujian peraturan daerah pasca putusan Mahkamah Konstitusi, dan kedua, untuk mengetahui pengujian peraturan daerah yang sejalan dengan sistem penyelenggaraan pemerintahan daerah dan sistem pengujian peraturan perundang-undangan di Indonesia. Metode penelitian ini menggunakan yuridis-normatif. Hasil penelitian menyimpulkan: pertama, urgensi rekonstruksi pengujian peraturan daerah pasca putusan Mahkamah Konstitusi, didasari pada: a) pemerintah pusat telah kehilangan kontrol dan koreksi terhadap peraturan daerah; b) desain pengujian peraturan daerah yang problematik di Mahkamah Agung; dan c) problematika kelembagaan MA dalam pengujian peraturan daerah. Kedua, desain pengujian peraturan daerah dan sistem pengujian perundang-undangan daerah yang diusulkan, antara lain: a) memperluas kewenangan klarifikasi pada pemerintah pusat dengan melakukan pembatalan/pencabutan peraturan daerah yang materi muatannya mengatur pelaksanaan tugas pembantuan dan/atau mengatur penjabaran lebih lanjut peraturan perundang-undangan yang lebih tinggi oleh pemerintah pusat/gubernur sebagai wakil pemerintah pusat; dan b) redesain hukum acara MA dalam pengujian peraturan perundang-undangan dengan cara mengakomodasi pengujian formil; mengganti konsep termohon menjadi para pihak yang meliputi pemohon, pemberi keterangan, dan pihak terkait; melaksanakan sidang terbuka untuk umum, membentuk bidang (majelis hakim) pengujian peraturan perundang-undangan; dan memperpanjang batas waktu penyelesaian pemeriksaan pengujian perundang-undangan.Kata kunci: pengujian, peraturan daerah, Mahkamah Agung, dan Mahkamah Konstitusi.

Abstract

Professional zakat, as a crucial instrument in Islamic economics, has experienced significant development alongside the increasingly complex dynamics of modern society. This study aims to analyze the legal construction of professional zakat through the maqashid shariah approach and to examine the formulation of policies and calculation mechanisms of professional zakat within the Indonesian legal system. The findings indicate that professional zakat has a strong normative foundation based on the method of analogy (qiyas syabah) to zakat on gold and agricultural produce, which is subsequently implemented in national regulations such as Law No. 23 of 2011 and the Indonesian Ulama Council’s fatwa. However, the implementation of professional zakat faces various challenges, particularly related to public awareness and structural obstacles in zakat management. This study emphasizes the importance of strengthening professional zakat literacy and integrating technology into zakat collection systems to enhance the effectiveness of professional zakat as a tool for empowering the Muslim community’s economy.

Abstract

Vehicle weight reduction is one of the most effective strategies for lowering energy consumption and emissions in both internal combustion and electric vehicles. Nanocomposites have attracted attention because they can significantly improve material properties at very low reinforcement contents. This study maps recent research on nanocomposites for lightweight automotive materials through a systematic review of 88 Scopus-indexed research articles published between 2021 and 2026. The number of articles increased more than sevenfold, from 4 in 2021 to 30 in 2026, and 59.1% of them appeared in the last two years. Polymer matrix nanocomposites dominate the field (45 articles; 51.1%), followed by aluminum matrices (27; 30.7%) and magnesium matrices (11; 12.5%). Graphene and its derivatives, together with carbon nanotubes (CNTs), are the most frequently studied reinforcements, while stir casting and its variants remain the main fabrication route for metal matrices. Nanoscale reinforcement, typically at 0.25–3 wt% in polymers and 1.5–10 wt% in metals, was reported to increase tensile strength by approximately 14–54% and to reduce the coefficient of friction by up to approximately 38%. One life cycle study reported a 28% reduction in component weight compared with a glass fiber composite. Three emerging research directions stand out: hybrid reinforcement, multifunctional materials (flame retardancy, electromagnetic interference shielding, and structural energy storage), and the use of machine learning for property prediction. A critical analysis also found that only 5.7% of the articles reported specific properties, that is, strength or stiffness per unit mass, even though these quantities determine the actual benefit of weight reduction. Most results were obtained on laboratory specimens (indicative technology readiness level 3–4), and the gains are bounded by an optimum filler content above which agglomeration reduces strength. The main open challenges include the dispersion and wettability of nanoparticles, large-scale production, recycling, and the lack of validation on real vehicle components.

Abstract

Keunggulan Ilmu Pengetahuan dan Teknologi memiliki ancaman keamanan sistem yang dapat munculkan kejahatan siber (cybercrime) menggunakan jaringan komputer. Penyalahgunaan kejahatan komputer mencakup, SQL Injection, Cross Site Scripting dan peretasan situs. Untuk itulah memetakan jaringan komunikasi pada sistem informasi berbasis web perlu dilakukan simulasi atau mitigasi pada sebuah sistem atau forensik digital. Proses forensik digital ini mengumpulkan informasi dari situs web (footprinting) dan jaringan komputer menggunakan metode dan sistem operasi Open-Source, adapun pengumpulan datanya menggunakan metode NIJ. Metode ini untuk mendapatkan barang bukti digital yang divisualisasikan ke bentuk network mapping. Hasil dari penelitian ini adalah rekomendasi untuk membantu administrator jaringan dalam mengambil keputusan berikut strategi keamanan sistem dan jaringan komputer melalui penguraian suatu kasus kejahatan siber yang berhasil terdeteksi.
