A REVIEW OF ISLAMIC CRIMINAL LAW ON THUGHTHROUGH ON THE NORTH SUMATRA-RIAU BORDER
Full text linkThuggery is a social phenomenon that often causes unrest and threatens public security, particularly in the North Sumatra-Riau border region. Thuggery in this region is often associated with violence, extortion, robbery, and threats carried out by groups or individuals. This study aims to examine thuggery from the perspective of Islamic criminal law, highlighting the causal factors, forms of action, and sanctions that can be imposed on perpetrators. The research uses a normative juridical method with a statutory and sociological approach. The results indicate that the main factors driving thuggery are difficult economic conditions, low levels of education, and weak law enforcement. In Islamic criminal law, acts of thuggery that contain elements of violence and threats to public security can be categorized as jarimah hirabah, namely crimes that damage public security and are considered major sins. Sanctions for perpetrators of hirabah are very severe, such as the death penalty, crucifixion, amputation, or exile, according to the severity of the crime committed, as stated in the Qur'an Surah Al-Maidah verse 33. This finding confirms that Islamic criminal law views thuggery as a serious crime that must be dealt with firmly to create security and public order. Effective law enforcement as well as a preventive and educational approach are essential to reduce the number of thuggery in the North Sumatra-Riau border region

Previous research has indicated that this strategy can support vocabulary acquisition and improve overall English language skills. The research focuses on the types of code-mixing frequently employed, students’ perceptions of this practice, and its impact on their comprehension of the material as well as their English proficiency. A descriptive qualitative approach is applied, with data collected through observation and audio recordings. Data analysis involves reduction, display, and conclusion drawing to gain an in-depth understanding of this phenomenon
Sistem Kewarisan Adat Simalungun (Studi Kasus Desa Rambung Merah, Kabupaten Simalungun)
No full textPenelitian ini bertujuan untuk mengkaji eksistensi hukum waris adat Simalungun di Desa Rambung Merah dalam konteks pluralisme hukum nasional Indonesia. Metode yang digunakan adalah penelitian lapangan (field research) dengan pendekatan kualitatif fenomenologis dan empiris-sosiologis, yang memfokuskan pada makna, persepsi, dan praktik masyarakat mengenai sistem kewarisan adat. Hasil penelitian menunjukkan bahwa hukum waris adat Simalungun, yang semula bersifat normatif dan mengikat, kini mengalami transformasi menjadi lebih fleksibel dan berbasis kesepakatan. Faktor pendorong perubahan ini adalah kesadaran masyarakat terhadap nilai keadilan, khususnya keadilan gender, serta berkembangnya moderasi beragama. Masyarakat Muslim di Desa Rambung Merah cenderung meninggalkan sistem waris adat karena dianggap diskriminatif terhadap perempuan, dan memilih hukum waris Islam sebagai acuan. Sementara masyarakat Kristen masih membuka peluang penggunaan hukum waris adat, asalkan dilaksanakan melalui musyawarah seluruh ahli waris. Diskusi menunjukkan bahwa pluralisme hukum di Indonesia mendorong munculnya model adaptasi dan kompromi dalam pelaksanaan hukum waris adat, sehingga tetap relevan dan selaras dengan perkembangan sosial serta nilai-nilai agama. Dengan demikian, hukum waris adat Simalungun tidak hilang, tetapi bertransformasi menjadi alternatif kondisional yang mengutamakan keadilan substantif dan harmoni keluarga di tengah masyarakat multikultural
Using an LSTM Neural Network to Improve Symmetric and Asymmetric GARCH Volatility Forecast
Full text linkVolatility forecasting is crucial for financial risk management, yet traditional models like GARCH struggle with nonlinearities and asymmetric effects. This study leverages Long Short-Term Memory (LSTM) neural networks to enhance symmetric and asymmetric GARCH models, addressing these limitations. By integrating LSTM with GARCH, GARCH-X, and Realized GARCH frameworks, we propose hybrid models (Baseline and Extended versions) to improve forecasting accuracy. Using daily data from FTSE 100, Nikkei 225, and S&P 500 indices (2000–2020), we compared hybrid models against traditional models. Results show that the Extended LSTM hybrid model outperforms both traditional GARCH-type models and the Baseline LSTM, capturing complex volatility patterns more effectively. The Extended model’s architecture, featuring ReLU, GRU, and dropout layers, mitigates over-smoothing and enhances responsiveness to market fluctuations. This research demonstrates LSTM’s potential to refine volatility forecasting, offering valuable insights for investors and risk managers
An Applied Computer Mathematics Approach to Transliteration: YOLOv8-Based Detection of Harah Jawoe Script
Full text linkTransliteration of traditional scripts such as Harah Jawoe, a regional variant of Jawi used in Acehnese manuscripts, is essential for preserving and understanding historical texts. While previous studies have focused on isolated character recognition, this research introduces a word-level transliteration approach using the YOLOv8 convolutional neural network (CNN) architecture. A dataset of 9,000 augmented images derived from the Hikayat Aceh manuscript was used to train and evaluate four YOLOv8 variants (small, medium, normal, and big). The results show that the big model achieved the most stable and reliable performance, with a peak mAP50–95 of 72.4% and an accuracy of 99.95%. These findings highlight the model’s capability to handle the structural complexity of Harah Jawoe script at the word level. This study offers a novel contribution by integrating object detection techniques with low-resource script transliteration, with implications for AI-driven cultural preservation and the digital accessibility of Southeast Asian manuscript heritag
