Abstract

Autism Spectrum Disorder (ASD) is a neurodevelopment syndrome decreasing sufferers' social interaction, communication skills, and emotional expression. Autism syndrome can be detected using an electroencephalogram (EEG). This study utilized the EEG of autistic people to support the classification study of machine learning schemes to produce the best accuracy. One of the best approaches to classify the EEG signal is The Linear Discriminant Analysis (LDA), a machine learning technique to classify autism and normal EEG signals. LDA was chosen because it can maximize the distance between classes and minimize the number of scatters by utilizing between and within-class functions. This method was combined with other methods: Independent Components Analysis (ICA) and Discrete Wavelet Transform (DWT), to improve the accuracy system. ICA removes artifacts or signals other than brain signals that can cause noise in the EEG signal, so the analyzed signal was a complete EEG signal without other factors. DWT can help increase noise suppression in the EEG signal and provide signal information through frequency and time representation. The EEG dataset was collated from 16 children (eight autistic and eight normal). The signals from the dataset were filtered by artifacts using ICA, decomposed by three levels through DWT, and classified using the Linear Discriminant Analysis (LDA) technique. Using the Confusion Matrix, the results reveal the best accuracy of 99%.

Abstract

The increasing dominance of global languages in digital spaces poses a threat to the preservation of regional languages, particularly among adolescents. This study examines the relationship between Fear of Missing Out (FoMO) and regional language maintenance among students at the Faculty of Teacher Training and Education (FKIP), Tadulako University. A quantitative approach was employed with a purposive sample of 200 active undergraduate students aged 17–21 years who regularly use social media platforms such as WhatsApp, Instagram, TikTok, and Twitter. Data were collected using two validated instruments: the Language Maintenance and Shift Scale (LMSS) and the FoMO Composite Scale (FMS). Descriptive statistics and Chi-Square analysis were used to examine the relationship between FoMO levels and regional language maintenance. Findings revealed a statistically significant relationship between FoMO and regional language maintenance (χ² = 93.05, p 0.01). Students with higher FoMO levels exhibited lower tendencies to maintain their regional language. Specifically, 38% of respondents with high FoMO demonstrated low language maintenance, while only 16% maintained a high level of commitment to their regional language. The results suggest that social anxiety and the need for digital connectedness contribute to the declining use of regional languages. This trend is exacerbated by the prevalence of global languages online, insufficient support from families and institutions, and a lack of cultural awareness. Efforts to preserve regional languages must involve collaborative strategies among families, educators, and policymakers to address psychosocial challenges and reframe local languages as relevant in digital and educational contexts.

Abstract

This study aims to analyze the influence of profitability and environmental performance on the value of companies in Sharia Commercial Banks in Indonesia for the 2020–2023 period. Profitability is measured using Return on Assets (ROA), while environmental performance is measured by PROPER. The value of the company is proxied by the Price to Book Value (PBV). The research method used is a quantitative approach with multiple linear regression analysis. The results of the study show that profitability has a positive and significant effect on the company's value partially. Environmental performance does not have a significant effect partially, but simultaneously, profitability and environmental performance have a significant effect on the company's value. These findings confirm the importance of strengthening profitability and implementing sustainable environmental management to increase company value. This research is expected to be a reference for practitioners and academics in the development of sustainability-oriented Islamic financial management.

Abstract

Accurate and reliable classification of autism spectrum disorder (ASD) from electroencephalography (EEG) signals remains challenging due to the inherently nonstationary, nonlinear, and multichannel nature of EEG data. These properties complicate the extraction of discriminative features that are both stable and computationally efficient. To address this challenge, this study proposes a compact deep-learning pipeline that integrates the Multivariate Empirical Wavelet Transform (MEWT) with EEGNet for ASD–EEG classification. MEWT decomposes multichannel EEG signals into spectrally aligned subbands while preserving inter-channel relationships. The resulting MEWT-based features are then processed by EEGNet, a lightweight convolutional neural network specifically designed for EEG-based learning tasks. Performance was evaluated using 5-fold cross-validation. The proposed MEWT with the the EEGNet model achieved a mean test accuracy of 98.35%, with consistently high precision (98.23%), recall (98.45%), F1-score (98.34%), and specificity (98.24%) across all folds. Confusion-matrix results indicated very few and well-balanced false positives and false negatives, supporting stable discrimination between ASD and control EEG segments. A one-sample one-tailed t-test against a 50% chance level confirmed that all evaluated metrics were significantly above chance (p < 0.0001). When benchmarked against previously reported results on the same dataset, the proposed approach slightly improved upon EMD with EEGNet (97.99%) and clearly outperformed EWT with EEGNet (95.08%), suggesting that MEWT-derived multichannel features are well matched to compact convolutional architectures for ASD–EEG analysis. Despite these strong results, the study is limited by a small, single-site cohort and the use of a single deep-learning model. Future work will focus on standardized retraining across multiple feature families and validation on larger and more diverse populations to further assess robustness and generalizability

Abstract

Lake Maninjau experiences periodic upwelling events that disrupt water quality, harm fish stocks, and pose socioeconomic challenges to surrounding communities. This study aimed to enhance upwelling prediction accuracy by integrating Vector Autoregressive (VAR) time series modelling with Support Vector Machine (SVM) classification. A five-year dataset (2020–2024) of daily climate variables surface temperature, precipitation, and wind speed was collected from NASA. Data stationarity was confirmed using Box-Cox transformations and Augmented Dickey-Fuller tests, while Granger Causality analysis revealed bidirectional relationships among the variables. The optimal forecasting model, VAR(17), was selected based on the Akaike Information Criterion (AIC), ensuring residuals met white-noise criteria. K-means clustering then labelled potential upwelling days, and these labels were employed to train SVM classifiers. An interactive dashboard was developed using Python and Streamlit to facilitate real-time forecasts and classification outputs. The VAR(17) model produced highly accurate forecasts, reflected by minimal error metrics (e.g., RMSE < 0.60). SVM classification of potential upwelling events achieved strong performance, consistently attaining F1-scores above 0.95. By merging time series forecasts with event classification, the hybrid VAR–SVM framework outperformed single-method approaches in identifying and predicting upwelling episodes. This integrated modelling strategy effectively addresses the complexity of upwelling in Lake Maninjau, enabling timely decision-making for fisheries management and local tourism stakeholders. Future work may incorporate additional environmental indicators (e.g., dissolved oxygen, pH) and extend dashboard functionalities to bolster sustainable resource management and community resilience
