Assessing Meteorological Drivers of PM2.5 in a Tropical Coastal Industrial Zone: A Comparative Study of Linear and Interpretable Machine Learning Models in Perai, Penang

Hongzhi Lu — 2026-05-27

Fine particulate matter (PM2.5) prediction in tropical coastal industrial zones is complicated by continuous industrial emissions, localized precipitation, sea-breeze circulation, and humidity-related measurement effects. This study developed a comparative and interpretable framework for daily PM2.5 estimation in the Perai Heavy Industrial Zone, Penang, using 97 concurrent observations from 2025-2026. Four meteorological predictors--temperature, wind speed, pressure, and precipitation--were evaluated with Multiple Linear Regression (MLR), Support Vector Regression (SVR), Random Forest (RF), and eXtreme Gradient Boosting (XGBoost). MLR achieved the strongest baseline predictive performance, indicating that simple linear structure can remain competitive when sample size is limited and temporal leakage is controlled. XGBoost was retained for interpretation because it captured non-linear local interactions more effectively than the other ensemble alternative. SHapley Additive exPlanations (SHAP) identified temperature and precipitation as the dominant drivers. The positive precipitation-PM2.5 relationship suggests that hygroscopic aerosol growth and optical sensor response may partly offset the expected wet-scavenging effect in this setting. The findings show that localized, interpretable modelling can support air-quality warning, sensor calibration, and meteorology-sensitive emission management in tropical industrial regions.

Risti Eka Helfiyan — 2026-06-27

This study explores the fusion of cultural heritage and modern innovation in contemporary kebaya design, focusing on the exploration of design trends, materials, and silhouettes. Kebaya, as a traditional Indonesian dress, has transformed into a dynamic fashion statement, integrated into modern lifestyles while maintaining its essence. Designers today are faced with the challenge of creating works that are not only visually appealing, but also have a depth of cultural meaning and adopt sustainable practices. This phenomenon raises the question of how the identity of the kebaya is maintained while being adapted through contemporary silhouettes, innovative materials, and modern details, extending to the realm of interactive media such as game development. Scratch-based game development plays a central role in this context, simplifying complex programming into intuitive blocks. This approach overcomes students' difficulties in translating abstract concepts into concrete designs. Through Scratch's drag-and-drop interface and instant preview, students can manipulate the kebaya in real-time, deepening their understanding of style transformations and combinations. This study aims to develop the process of exploring kebaya trends, identifying natural materials, and analyzing the aesthetic results and uniqueness of kebaya trends. The findings confirm the potential of visual programming as a bridge between design theory and creative practice, strengthening the understanding of the aesthetics and functionality of modern kebaya.

Sirait Widya Sia Ulina — 2026-06-27

The revitalization of traditional textiles in contemporary fashion often faces bottlenecks during the initial design phase due to high costs and structural constraints in physical prototyping. This study introduces "The Scratch Approach" as an innovative, low-cost digital pre-prototyping framework for transforming traditional Batak Ulos into contemporary vest collections. Guided by the ADDIE model, this qualitative research gathered insights from fashion industry experts, traditional artisans (partonun), and fashion academics. The empirical data were evaluated using a rigorous six-stage thematic analysis. The findings indicate that while physical prototyping heavily limits design exploration, Scratch effectively serves as an accessible digital sandbox. Through its modular sprite features and customizable visual blocks, the platform democratizes the design process, enabling rapid garment silhouette iterations, step-by-step assembly animations, and texture simulations without the risk of destroying rare, expensive physical textiles. Ultimately, this study provides a validated framework that successfully bridges cultural heritage preservation with modern sustainable fashion demands.

Girls Day in The Digital World: Developing Creativity Through Dress Up Games in The Scratch App

Aqilah Yuliant — 2026-06-27

The paradigm shift in contemporary fashion design toward the digital realm represents a fundamental revolution, opening unique opportunities for children to interact innovatively with mode. However, the explicit integration of fashion design with children's creativity through digital platforms is often suboptimal. This research aims to fill this gap by developing a Scratch-based dress-up game prototype titled "Girls Day" as a tool to stimulate creativity, simultaneously identifying the key game elements effective in encouraging creativity and analyzing their potential impact on children's expressive abilities. The ADDIE methodology (Analysis, Design, Development, Implementation, Evaluation) is adopted as a systematic and iterative framework for the game's development and evaluation, effectively integrating artistic aspects with technological skills. As an anticipated main finding, the game is expected to facilitate active and constructive learning, with interactive features that significantly enhance children's creative expression and visual literacy in fashion design. It is concluded that this Scratch-based game prototype is effective as an empowering digital educational tool, successfully integrating fashion design concepts with basic computational skills. It is recommended that digital products of this kind be integrated into project-based learning curricula and that further research be conducted on their long-term effectiveness.

Maroccan Architectural Traces in Fashion: A Dress-up Fashion Design Based on Traditional Aesthetic Structures

Faza Rahmanita — 2026-06-27

This research explores the integration of Moroccan architectural aesthetics into dress-up fashion design and the potential use of the Scratch platform as a design and education tool. Contemporary fashion design paradigms emphasise cultural identity and sustainability, yet dress-up fashion design in Indonesia still shows homogeneity. We identify a gap in the exploration of non-Western architectural aesthetics and propose an innovative approach that incorporates Moroccan visual heritage. Research objectives include developing a process for applying art architecture to fashion design, identifying natural materials for patterns, and analysing the aesthetics and uniqueness of the resulting designs, including implementation through Scratch. Using the ADDIE methodology and qualitative data collection through interviews, document analysis, and observations from experts and practitioners, we found that Moroccan architectural elements such as geometric patterns, curvilinear shapes, and ornamental details are highly relevant. Scratch proved effective as an intuitive digital prototyping tool, facilitating interactive visualisation and rapid design iteration. This research shows that the integration of Moroccan architectural aesthetics, supported by Scratch, not only enriches creative expression but also offers an efficient and interactive design method in fashion design practice and education.

Vest Design Innovation from Denim Waste: Exploration of Sustainable Weaving Techniques and Scratch Touch

Mahdiyah Zarifah — 2026-06-27

This study investigates design innovation for vest products using denim waste processed through weaving techniques, responding to the increasing demand for sustainable and circular approaches in the contemporary fashion industry. Although vest garments are widely popular in Indonesia, the exploration of upcycled textile materials particularly denim waste remains limited and offers significant opportunities for both aesthetic and functional development. The aim of this research is to identify effective processing techniques for transforming denim waste into woven vest materials, to design vest products that integrate intentional scratch-touch aesthetics as a physical design element, and to examine the educational potential of the Scratch digital platform as a tool for visualising and communicating the upcycling process. This study distinguishes clearly between the two concepts: (1) scratch touch as a physical aesthetic finishing method applied to the woven denim material, and (2) the Scratch platform as a digital, non-material educational medium. Using a qualitative design approach supported by the ADDIE framework, the research includes analysis of denim waste characteristics, development of woven prototypes, design of vest products, and creation of an interactive Scratch-based visualisation. Data were collected through expert interviews, observations, and document analysis. The findings show that denim waste can be effectively reconstructed through modified weaving techniques to produce structurally stable and visually appealing materials suitable for vest design. The scratch-touch aesthetic enhances the product narrative and aligns with sustainable fashion values, while the Scratch platform successfully supports user engagement and increases public understanding of upcycling processes. In conclusion, woven denim waste presents strong potential as an innovative sustainable material for fashion products when combined with thoughtful aesthetic finishing. The study recommends broader implementation of weaving-based upcycling techniques in fashion education and encourages the use of digital platforms such as Scratch to strengthen sustainability literacy among younger audiences.
