Abstract

Accurate forecasting of financial time series remains a complex challenge due to asset price behaviour's non-stationary, nonlinear, and cyclical nature. While Long Short-Term Memory (LSTM) networks have shown promise in modeling sequential dependencies, they often struggle to capture periodic structures inherent in financial data. This study proposes a hybrid forecasting framework that integrates temporal pattern recognition techniques—specifically seasonal decomposition, wavelet transforms, and moving averages—into a recurrent neural architecture to improve predictive performance in cyclical markets. Using historical data from five representative financial instruments, the hybrid model enriches the LSTM input space with statistically significant temporal features, thereby enabling more comprehensive learning of both long-term dependencies and structural temporal patterns. Empirical results demonstrate that the proposed model significantly outperforms traditional LSTM baselines in terms of Root Mean Squared Error (RMSE), particularly in assets exhibiting strong cyclical behavior. The residual component from seasonal decomposition emerges as the most influential feature, reinforcing the importance of capturing irregular deviations in financial forecasting. This research contributes a structured and generalizable approach to combining temporal pattern recognition with deep learning, offering improved accuracy and interpretability for practitioners and researchers in computational finance

Abstract

Occupational accidents in shipyard industries remain a significant concern due to the complex and high-risk nature of shipbuilding and repair activities. Operations such as working at heights, confined space entry, welding, heavy lifting, and exposure to hazardous substances contribute to elevated accident rates and severe consequences, including fatalities and economic losses. This study aims to analyze occupational accidents in shipyards by integrating Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) using a Systematic Literature Review (SLR) approach. The objective is to identify dominant accident types, prioritize critical risks, and determine root causes to support evidence-based safety improvements. The research employed a systematic literature review method by collecting peer-reviewed articles from major scientific databases published between 2010 and 2024. Relevant studies were selected based on predefined inclusion and exclusion criteria. Data were extracted and synthesized to identify common failure modes, risk parameters (Severity, Occurrence, Detection), Risk Priority Number (RPN) values, and causal relationships derived from FTA models. The PRISMA framework was applied to ensure a transparent and structured selection process. The results indicate that the most dominant occupational accidents in shipyards include falls from height, confined space incidents, fire and explosions during hot work, crushing injuries from heavy lifting operations, and electrical accidents. FMEA analysis revealed that confined space operations and welding activities consistently present the highest RPN values. FTA findings demonstrate that these accidents are commonly caused by a combination of human factors, equipment failures, inadequate supervision, insufficient safety procedures, and weak organizational safety culture. The integration of FMEA and FTA provides a comprehensive analytical framework that combines quantitative risk prioritization with qualitative root cause identification. This integrated approach enhances the effectiveness of occupational risk assessment in shipyard environments. Academically, the study contributes to the development of integrated risk analysis methodologies, while practically it offers structured recommendations for improving safety management systems in shipyard industries.

Abstract

The rapid growth of internet usage and the dominance of mobile device access have significantly transformed website development practices. Websites are no longer accessed primarily through desktop computers but through various devices with different screen sizes, particularly smartphones. This shift requires adaptive design strategies to ensure optimal accessibility and usability. However, many websites still employ static layouts that are not responsive, leading to display distortions, navigation difficulties, and reduced user experience, especially on mobile devices. This study aims to implement Responsive Web Design (RWD) to improve website accessibility and evaluate its effectiveness through quantitative measurement. The research adopts an experimental method using a before-and-after testing approach. The selected website is first evaluated in its original (non-responsive) condition using accessibility assessment tools based on Web Content Accessibility Guidelines (WCAG) standards. Subsequently, RWD principles—including fluid grids, flexible images, media queries, and a mobile-first approach—are implemented. Accessibility testing is then repeated to measure improvements. The results indicate that the implementation of Responsive Web Design significantly enhances website accessibility across multiple devices. Improvements are observed in layout adaptability, text readability, navigability, and overall compliance with WCAG principles. The responsive layout reduces horizontal scrolling, optimizes content structure, and enhances user interaction efficiency. In conclusion, Responsive Web Design is an effective technical solution for addressing accessibility challenges in multi-device environments. Although responsiveness alone does not guarantee full accessibility compliance, its integration with accessibility standards contributes substantially to improving digital service quality. This study provides empirical evidence and a structured implementation framework that can serve as a reference for developers and institutions seeking to enhance website accessibility and user experience.

Abstract

Industri galangan kapal merupakan sektor industri manufaktur berat yang memiliki tingkat risiko kecelakaan kerja relatif tinggi akibat aktivitas seperti pengelasan, pemotongan baja, pekerjaan di ruang terbatas, serta pekerjaan di ketinggian. Kondisi ini menuntut adanya pemahaman yang memadai mengenai Keselamatan dan Kesehatan Kerja (K3), tidak hanya bagi pekerja, tetapi juga bagi mahasiswa Teknik Industri sebagai calon tenaga profesional yang akan terjun ke lingkungan industri. Namun demikian, pembelajaran K3 di perguruan tinggi masih cenderung bersifat teoritis sehingga diperlukan intervensi edukatif yang lebih aplikatif. Pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan mahasiswa Teknik Industri mengenai K3 di lingkungan galangan kapal serta mengevaluasi efektivitas pelatihan yang diberikan. Metode yang digunakan adalah pendekatan kuantitatif dengan desain pre-experimental tipe one group pretest–posttest. Kegiatan dilaksanakan melalui tahapan persiapan, pelaksanaan pelatihan, dan evaluasi. Instrumen yang digunakan berupa tes pengetahuan (pre-test dan post-test) untuk mengukur peningkatan pemahaman peserta. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada nilai rata-rata post-test dibandingkan pre-test, yang mengindikasikan bahwa pelatihan K3 efektif dalam meningkatkan pengetahuan mahasiswa mengenai identifikasi bahaya, penggunaan alat pelindung diri (APD), serta pengendalian risiko di galangan kapal. Selain peningkatan aspek kognitif, pelatihan juga mendorong tumbuhnya kesadaran dan sikap positif terhadap budaya keselamatan kerja. Dengan demikian, pelatihan K3 bagi mahasiswa Teknik Industri di galangan kapal merupakan intervensi yang relevan dan efektif dalam mempersiapkan mahasiswa menghadapi lingkungan kerja berisiko tinggi. Kegiatan ini diharapkan dapat menjadi model pembelajaran berbasis praktik yang mendukung pembentukan budaya keselamatan sejak masa pendidikan.
