Literary Landscapes: Scaffolding Language Acquisition Through Thematic Analysis and Creative Engagement in a Saudi ESL Context
Authors: M. Saadawi Ahmed
Published: February 2025

This mixed-method study investigates the effectiveness of integrating literature into English language instruction for students enrolled in diploma programs at a Saudi Arabian university, with a focus on how thematic analysis and creative pedagogical strategies enhance vocabulary retention, grammar comprehension, and learner engagement. Conducted over seven months, the research involved 120 diploma students (aged 18–20) divided into six groups, each facilitated by one of six English as a Second Language (ESL) lecturers. Data collection included pre- and postintervention vocabulary tests, grammar quizzes, classroom observations, and semistructured interviews with instructors. Findings revealed that students exposed to culturally relevant literary texts, such as simplified Arab folktales (Juha and the Donkey), demonstrated a 22% improvement in vocabulary retention, with terms like “honesty” and “tradition” retained most effectively. Grammar accuracy, particularly in past tense usage, increased by 12% following lessons using narratives like “The Gift of the Magi”. Creative activities, including role-playing and group discussions, significantly reduced speaking anxiety, with 80% of students reporting greater confidence. However, engagement with Western texts (e.g., The Ant and the Grasshopper) was notably lower (30%) compared to locally resonant materials (70%). Key challenges included limited access to Arabic-English literary resources, as all lecturers relied on self-adapted materials, and insufficient training in literaturebased pedagogy, with three instructors explicitly stating a lack of confidence in designing creative lessons. Institutional pressure to prioritize standardized exam preparation further constrained implementation of innovative methods. The study proposes practical steps to address these challenges, beginning with the integration of Arab folktales and Saudi-authored texts into diploma curricula to align lessons with students’ cultural identities. Professional development workshops for ESL lecturers should be prioritized to equip them with strategies for designing literature-driven activities such as thematic role-plays and vocabulary games. Partnerships with Saudi publishers could facilitate the development of simplified literary resources tailored to diploma students’ proficiency levels. Finally, assessment frameworks should be revised to balance exam preparation with creative, culturally responsive tasks, ensuring alignment with institutional goals while fostering engagement.
Analisa Yuridis Pelanggaran Administrasi Dalam Perkawinan Poligami. (Studi Kasus : Putusan No 158/Pdt.G/2024/PTA.Bdg)
Authors: Hadi Fajri Setiyo , Fattinudin Muhammad
Published: February 2025

Penelitian ini bertujuan untuk memberikan analisis hukum terhadap praktik poligami berdasarkan Kompilasi Hukum Islam (KHI) dan Hukum Perkawinan di Indonesia serta dampaknya terhadap pengendalian jumlah penduduk. Poligami di Indonesia diatur dalam KHI, dan laki-laki yang ingin melakukan poligami harus memenuhi syarat tertentu, seperti mendapat izin dari istri pertama atau pengadilan. Namun dalam praktiknya, pelanggaran terhadap aturan tersebut sering terjadi dan menimbulkan permasalahan hukum dan administratif. Penelitian ini menggunakan pendekatan  Metode kualitatif dengan mengkaji berbagai peraturan perundang-undangan, putusan pengadilan, dan literatur terkait. Wawancara juga dilakukan terhadap pengacara, petugas administrasi kependudukan, dan pelaku poligami. Temuan penelitian menunjukkan bahwa meskipun KHI dan UU Perkawinan memberikan kerangka hukum yang jelas bagi poligami, penerapannya seringkali menemui kendala dalam praktiknya. Poligami seringkali dilakukan tanpa prosedur yang benar, seperti tanpa izin istri pertama atau persetujuan pengadilan. Hal ini menimbulkan berbagai permasalahan hukum, termasuk sanksi administratif dan ketidakpastian hukum bagi istri dan anak yang berpoligami. Selain itu, pelanggaran peraturan poligami juga berimplikasi pada pengendalian populasi. Dalam banyak kasus, status perkawinan poligami tidak tercatat dengan baik pada dokumen kependudukan seperti kartu keluarga atau akta kelahiran anak. Hal ini menyebabkan kesulitan dalam pengelolaan keluarga dan hak-hak sipil.Studi ini menyerukan penuntutan yang lebih ketat terhadap pelanggaran poligami, keterlibatan hukum yang lebih besar dari masyarakat, dan sistem pengendalian populasi untuk memastikan bahwa semua pernikahan dicatat dengan benar dan hak-hak keluarga terlindungi.

Authors: Campos-Salazar José M. , Santander Felipe , Larraín Sebastián
Published: February 2025

The dynamic performance of control strategies for an X-filter process is critically analyzed, emphasizing the advantages of model predictive control (MPC) over traditional proportional-integral (PI) control. A detailed simulation model, grounded in the linearized expressions of the X-filter process, was developed using MATLAB-Simulink, with parameters systematically defined and tested under various disturbance scenarios. Key performance indicators, including steady-state behavior, oscillation magnitude, and control effort, were assessed. Results demonstrate that MPC significantly enhances system responsiveness, achieving a steady state more rapidly than PI controllers, with notable reductions in oscillatory behavior across key process variables. Specifically, oscillations in the manipulated variable mi were effectively mitigated under MPC control, thereby safeguarding hydraulic pump integrity. Statistical analysis of standard deviations for controlled variables revealed that MPC reduces variability in h1, h2, and dp by 9%, 24%, and 32% respectively, underscoring its superior ability to maintain stability amidst high-frequency noise and external disturbances. The average position deviation for manipulated variables further illustrates the efficiency of MPC, with reductions of up to 92% in specific instances. Robustness testing confirms MPC's resilience to disturbances in critical input variables, showcasing its adaptability in complex industrial environments. Overall, the findings affirm that MPC not only optimizes set-point tracking but also enhances process control precision, providing a compelling case for its implementation in advanced industrial applications.

Authors: Triwijaya Helmy Yulian , Sami’an S. , Hardjomuljadi Sarwono
Published: February 2025

The COVID-19 pandemic caused significant disruptions in the execution of construction contracts, leading to disputes related to force majeure claims. This article examines the force majeure dispute resolution mechanism in construction contracts at XYZ Ltd, an Indonesian SOE. This research employs normative and empirical legal approaches, with a case study on XYZ Ltd. Primary data were obtained through analysis of construction contract documents, a legal opinion from the State’s Attorney, and other relevant documents. Secondary data includes statutory regulations, court decisions, and related legal literature. The data were analyzed using qualitative content analysis and case analysis techniques. The research findings reveal that XYZ Ltd resolved disputes with service providers through negotiation, taking into account the legal opinion from the State’s Attorney, which recognized the pandemic as force majeure but emphasized the principles of pacta sunt servanda and good faith. The involvement of the BPKP through a claim audit strengthened accountability and good corporate governance. The audit results served as the basis for negotiations to minimize state financial losses. This research highlights the complexity of applying force majeure clauses in construction contracts, the importance of renegotiation, and the crucial role of legal opinions and independent audits in dispute resolution at SOEs.

Authors: Qadri Qadri , Sami’an S. , Saputro Adi
Published: February 2025

Overhead cost claim disputes are a crucial issue in Indonesia’s construction industry. Therefore, this research aims to comprehensively analyze the legal aspects of overhead cost claims in construction contracts in Indonesia, encompassing the legal basis, types of claimable costs, legal conditions triggering claims, claim submission requirements, calculation methods, and dispute resolution mechanisms. A normative juridical method is employed to achieve this objective, using a statute, case, and conceptual approach. Data is sourced from statutory regulations, construction contract standards, jurisprudence, and legal literature and then analyzed qualitatively. Substantively, this research finds that the legal basis for overhead cost claims in Indonesia involves a complex interaction between Law Number 2 of 2017, Government Regulation Number 22 of 2020, the Civil Code, and contract standards such as FIDIC. Furthermore, overhead claims must be based on wanprestasi (breach of contract), force majeure, or variation orders and must meet the requirements of notification, documentation, accountable calculation, and causality. In terms of calculation, the accepted method must be by the principle of compensation. As for dispute resolution, it can be through mediation, conciliation, arbitration, or litigation, with the caveat that the selection of a mechanism depends on a case-by-case analysis. Overall, this research provides a comprehensive understanding of the legal aspects of overhead cost claims in construction contracts in Indonesia.

The effect of neighbouring group participation and possible long range remote group participation in O-glycosylation
Authors: Das Rituparna , Mukhopadhyay Balaram
Published: February 2025

Stereoselective glycosylations are one of the most challenging tasks of synthetic glycochemists. The protecting building blocks on the glycosides contribute significantly in attaining the required stereochemistry of the resulting glycosides. Strategic installation of suitable protecting groups in the C-2 position, vicinal to the anomeric carbon, renders neighbouring group participation, whereas protecting groups in the distal C-3, C-4, and C-6 positions are often claimed to exhibit remote group participation with the anomeric carbon. Neighbouring group participation and remote group participation are being widely studied to help the glycochemists design the synthetic protocols for multistep synthesis of complex oligosaccharides and in turn, standardise the process of the glycosylation towards a particular stereochemical output. While neighbouring group participation has been quite effective in achieving the required stereochemistry of the produced glycosides, remote participation exhibits comparatively less efficacy in achieving complete stereoselectivity in the glycosylation reactions. Remote participation is a still highly debated topic in the scientific community. However, implementing the participating role of the remote groups in glycosylation reactions is widely practised to achieve better stereocontrol and to facilitate the formation of synthetically challenging glycosidic linkages.

The rising unemployment rate in Nigeria highlights the need for self-employment through micro business development. Scholars emphasize the importance of social capital in employment generation. This study examines the role of social capital in micro business development in Ebonyi State, Nigeria, focusing on how network assets relate to micro business associations and how relational assets influence self-employment generation. Using a correlation research design and factor analysis, data from 389 respondents were analyzed via Pearson correlation. Results showed a significant positive correlation between network assets and micro business associations (r=0.72, p<0.01) and between relational assets and self-employment generation (r=0.52, p<0.01). The study concludes that social capital significantly enhances micro business development, driving socio-economic activities and job creation. It recommends institutionalizing social capital among micro business owners to boost economic growth and address youth unemployment.

Influence of Density and Compressive Strength on Intrinsic Air Permeability and Porosity of Hybrid Fibre-Reinforced Lightweight Foamed Concrete
Authors: Anuar Izzat , Ismail Sallehan , Saleh Ani Maslina
Published: February 2025

Given the growing demand for sustainable and environmentally friendly building materials, lightweight foamed concrete (LFC) is a suitable choice for semi-structural applications. However, the low strength and high water absorption of LFC make it an unsuitable material for large structures. The building industry does not consider LFC cost-effective unless it undergoes strengthening with other materials, as its mechanical strength and durability are insufficient for building use. This paper aims to augment the mechanical and durability characteristics of hybrid fibre-reinforced lightweight foamed concrete (HFRLFC) by using nylon and polypropylene (PP) fibres under a sealed curing condition.  A strict experimental method was used to compare HFRLFC to control mixtures (which didn't have any fibres), single-fibre mixtures (0.4% nylon), and hybrid-fibre combinations (0.13% PP and 0.27% nylon) at a constant 1:1 mixing ratio. The findings demonstrated a notable initial improvement in mechanical strength and durability, as well as heightened resistance to lower permeability via less cracking and improved compaction. Mixed HFRLFC with 0.27% nylon and 0.13% PP had better mechanical and long-lasting properties than control mixes and LFC with only nylon fibre.  HFRLWC exhibits the synergistic reinforcement mechanisms of hybrid fibres, improving their structural integrity and durability over time.  These findings emphasize the potential of HFRLFC as a sustainable and effective material for semi-structural applications.

Published: February 2025

In designing of Unmanned Aerial Vehicle (UAV), selection of an optimal wing design is a crucial part of complete UAV design process. This research explores the different aerodynamic parameters and the comparison of different wing planforms to ascertain the optimal wing design and improve the overall efficiency of an UAV. The computational analysis using XFLR5 and Open-VSP software is studied to investigate the various aerodynamic parameters of wing. The impact of aspect ratio, taper ratio, wing reference area, coefficient of lift and drag, and stall angle of attack are examined using the Analytical Hierarchy Process (AHP). The results emphasize the importance of different wing planforms and create easier selection of planform for the UAV designers. The study does not only provide the values for operating parameters but also offers practical guidance for design optimization. The semi tapered, and moderate tapered (λ = 0.5) wings are the good choice to select at the initial phase of design. The highly tapered and elliptical wings provide higher lift but are not efficient in the stalling conditions. Furthermore, the rectangular wing provides elliptical lift distribution, but it is inefficient in the lift generation.
