Abstract

General Background: Liquid crystal photovoltaics and photoelectric phenomena have garnered significant scientific interest due to their applications in optoelectronic sensing, light energy conversion, and functional soft matter systems. Specific Background: Methyl red, as an organic dye, possesses excellent visible light absorption capacity and fast photoionization characteristics, making it suitable for investigating photocurrent generation mechanisms in symmetric nematic cells. Knowledge Gap: Previous studies have either provided only qualitative descriptions of the photovoltaic effect or examined limited thickness ranges, lacking systematic exploration of how cell thickness and temperature-dependent activation processes influence photocurrent behavior in dye-doped liquid crystal systems. Aims: This study systematically investigates stationary and non-stationary photocurrents in symmetric nematic liquid crystal cells doped with methyl red across a wide range of thicknesses (1-100 μm) and temperatures. Results: The activation energy for charge carrier transport ranges from 0.05 eV to 0.87 eV across different cell thicknesses, with activation energy increasing as cell thickness decreases, while peak photocurrent values increase with decreasing thickness due to enhanced capacitance effects. Novelty: This work provides the first comprehensive quantitative analysis linking cell thickness to activation energy variations in methyl red-doped nematic systems. Implications: These findings advance understanding of charge transport mechanisms in dye-doped liquid crystals and offer critical design considerations for low-voltage optoelectronic devices, light sensors, and advanced liquid crystal-based energy conversion systems.Keywords : Photocurrent, Methyl Red, Nematic Liquid Crystal, Activation Energy, Cell ThicknessHighlight : Peak photocurrent amplitude increases with decreasing cell thickness due to enhanced capacitance effects. Activation energy ranges from 0.05 eV to 0.87 eV, rising as layer thickness decreases. Light absorption in thicker nematic layers increases steady-state current through reduced grounded electrode transmission.

Abstract

General Background: The pancreas demonstrates adaptive capacity to modify enzymatic secretion in response to dietary composition, a mechanism essential for efficient nutrient hydrolysis and metabolic homeostasis. Specific Background: Organochlorine pesticides, particularly hexachlorocyclohexane (HCH) and tetramethylthiuram disulfide (TMTD), have been associated with digestive system disorders, yet their effects on pancreatic enzymatic adaptation and intestinal enzyme-forming function remain inadequately characterized. Knowledge Gap: The extent to which chronic pesticide exposure disrupts the pancreas's ability to adapt enzyme secretion to qualitative changes in food composition, and how these compounds affect small intestinal hydrolytic capacity, has not been systematically investigated. Aims: This study examined the effects of chronic HCH (1/20 LD₅₀ for 30 days) and TMTD (1/20 LD₅₀ for 60 days) exposure on pancreatic enzymatic adaptation to protein-rich and fat-rich dietary stimuli in rats, alongside assessment of small intestinal enzyme-forming function. Results: Control animals exhibited adaptive increases in protease activity following protein intake and lipase activity following fat intake within intestinal chyme; HCH exposure delayed these adaptive responses, whereas TMTD completely abolished pancreatic enzymatic adaptation to food quality, with both pesticides significantly suppressing intestinal enzyme activities. Novelty: This investigation provides the first systematic evidence that organochlorine pesticides disrupt both pancreatic adaptive mechanisms and intestinal hydrolytic enzyme function in a dose-dependent and time-dependent manner. Implications: These findings indicate that pesticide exposure compromises digestive efficiency through dual mechanisms affecting pancreatic regulation and intestinal enzymatic capacity, potentially contributing to metabolic dysfunction in exposed populations.Keyowrds : Pancreatic Enzyme Adaptation, Hexachlorocyclohexane Toxicity, Tetramethylthiuram Disulfide, Intestinal Enzyme Function, Organochlorine Pesticide EffectsHighlight : Chronic HCH exposure delays pancreatic adaptive response to dietary protein and fat stimuli. TMTD completely abolishes enzymatic adaptation mechanisms in exocrine pancreatic secretion regulation. Organochlorine pesticides suppress intestinal enzyme activity while paradoxically increasing mucosal amylase levels.

Abstract

General Background: Early childhood education requires learning media that not only support cognitive development but also stimulate multiple intelligences, particularly interpersonal intelligence, which is essential for children’s social growth. Specific Background: Science learning activities in early childhood settings are often limited to teacher-centered approaches and lack instructional media that encourage active social interaction among children. Knowledge Gap: There is limited availability of science-based instructional media specifically designed to stimulate interpersonal intelligence through collaborative experimental activities for children aged 5–6 years. Aims: This study aims to develop a science experiment book as an instructional medium to stimulate multiple intelligences, particularly interpersonal intelligence, among children aged 5–6 years at TK Idhata Beka. Results: Using a Research and Development approach involving needs analysis, product design, expert validation, and limited field trials, the findings show that the developed science experiment book was categorized as very feasible in terms of media and content quality, and its implementation led to improvements in children’s interpersonal abilities, including cooperation, communication, and peer interaction during science-based experimental activities, indicating that the science experiment book has strong potential as an effective learning medium for supporting the development of interpersonal intelligence in early childhood education. Highlights: Expert appraisal classified the developed learning resource as very valid in content and media aspects. Group-based experimental sessions increased children’s peer dialogue and shared task completion. Structured hands-on activities supported observable progress across social interaction indicators. Keywords: Science Experiment Book, Multiple Intelligences, Interpersonal Intelligence, Early Childhood.

Abstract

General Background: Cyberbullying detection in Indonesian social media has become increasingly important due to rapid digital communication growth and complex informal language usage. Specific Background: Automated identification remains challenging because Indonesian online discourse frequently contains slang, ambiguity, sarcasm, and class imbalance, limiting the capability of conventional statistical and earlier deep learning approaches. Knowledge Gap: Prior studies have emphasized traditional classifiers and encoder-based Transformers such as IndoBERT, while generative text-to-text architectures like T5 and their comparison with hybrid feature fusion strategies remain underexplored in Indonesian-language corpora. Aims: This study systematically compares three modeling scenarios—T5 Base, Hybrid (T5 + TF-IDF), and Enhanced (T5 + TF-IDF + sentiment)—to evaluate their performance in detecting cyberbullying from 20,000 Indonesian social media comments with naturally imbalanced distribution. Results: Experimental findings show that T5 Base achieves the highest test Accuracy (0.8325) and Macro F1-Score (0.8329), while Hybrid and Enhanced models yield slightly lower yet competitive performance. The results indicate that contextual semantic representations learned by T5 sufficiently capture explicit and implicit abusive expressions, and additional statistical and sentiment features do not yield superior classification outcomes. Novelty: This research provides empirical evidence that a standalone text-to-text Transformer architecture can outperform hybrid feature fusion strategies in Indonesian cyberbullying detection under limited training data conditions. Implications: The findings support the adoption of end-to-end Transformer-based models for scalable, robust, and linguistically adaptive monitoring systems in low-resource social media environments. Highlights: The standalone text-to-text architecture produced the strongest test-set metrics among all evaluated scenarios. Integration of statistical weighting and sentiment signals did not surpass the semantic-only configuration. Stable generalization was maintained despite limited training allocation and naturally imbalanced data distribution. Keywords: Text Classification, Social Media Analysis, Transformer Models, Indonesian Language, Cyberbullying Detection.

Abstract

General Background: Organophosphorus pesticides are widely used agricultural chemicals with known biological effects, yet their impact on digestive physiology remains incompletely understood. Specific Background: Previous research has demonstrated that chlorophos, an organophosphorus compound, suppresses intestinal enzyme activity in experimental animals, with lipase showing particular sensitivity, though comprehensive characterization of organophosphorus effects on small intestinal enzyme systems is lacking. Knowledge Gap: The detailed dose-dependent and time-dependent effects of butiphos, a commonly used organophosphorus pesticide, on the complete spectrum of intestinal digestive enzymes and the reversibility of these effects have not been systematically investigated. Aims: This study investigated the effects of acute and chronic butiphos exposure at varying doses on key small intestinal enzymes including monoglyceride lipase, glycyl-valine dipeptidase, invertase, alkaline phosphatase, and amylase in laboratory rats. Results: Monoglyceride lipase activity was consistently and profoundly suppressed (up to 9-fold reduction) across all exposure regimens, while other enzymes exhibited dose- and time-dependent wave-like fluctuations with transient increases or decreases followed by partial recovery; cessation of pesticide administration resulted in normalization of enzymatic activity and mucosal mass. Novelty: This research provides the first comprehensive characterization of butiphos-induced alterations in intestinal enzyme-forming function, revealing selective esterase inhibition and reversible enterocyte dysfunction. Implications: These findings highlight potential impairment of digestive efficiency during chronic organophosphorus pesticide exposure and underscore the high sensitivity of enterocyte enzymatic systems to these agricultural compounds.Keywords : Organophosphorus Pesticides, Intestinal Enzymes, Monoglyceride Lipase, Butiphos, Digestive FunctionHighlight : Monoglyceride lipase activity consistently suppressed regardless of butiphos dose or duration. Protein and carbohydrate enzymes showed wave-like fluctuations with partial recovery periods. Enzymatic activity and mucosal mass normalized after pesticide administration cessation.

Abstract

General Background: Digital transformation has fundamentally altered administrative work through generative artificial intelligence (GAI), which enables human activity in developing novel content and creative solutions beyond existing paradigms. Specific Background: While GAI's theoretical frameworks are established globally, its integration with digital project management success within Arab administrative structures remains underexplored, particularly regarding how GAI dimensions interact with organizational efficiency. Knowledge Gap: Despite GAI's growing prominence, empirical evidence linking its specific dimensions—task definition, AI contribution, interaction methodology, AI structure, and human personality—to digital project management outcomes in developing economies is limited. Aims: This study investigates the relationship between GAI dimensions and digital project management success (organizational structure, technology, and digital innovation) among 188 employees at Iraq's Karbala Investment Authority using structural equation modeling. Results: GAI explains 43% of variance in digital project management success, with human personality (β=0.402), task definition (β=0.343), and AI contribution (β=0.278) showing significant positive effects, while interaction methodology and AI structure demonstrated non-significant impacts. Novelty: This research provides the first empirical Arabic-context framework demonstrating that human skills, behavior, and experience remain the primary drivers of digital project success when combined with GAI. Implications: Organizations must invest in behavioral and technical capabilities through command engineering training and digital simulation to bridge skills gaps and enable human-machine symbiosis for competitive advantage.Keywords : Generative Artificial Intelligence, Digital Project Management, AI Dimensions, Organizational Digital Transformation, Human-AI CollaborationHighlight : Human skills and behavior remain the primary driver of digital project success. Clear task definition significantly enhances AI-powered project automation and efficiency outcomes. AI contribution and human personality show stronger impact than technical infrastructure flexibility.

Abstract

General Background Subjective well-being is a central construct in psychology that reflects individuals’ evaluations of life satisfaction and emotional experiences, particularly within social and cultural contexts such as fandom communities. Specific Background Fans of idol groups often form strong emotional attachments and social networks that may shape their psychological functioning, including perceived happiness and life satisfaction. Knowledge Gap Despite extensive research on well-being across populations, limited empirical attention has been directed toward idol fandom communities, particularly JKT48 fans in regional contexts. Aims This study examines the relationship between social support and celebrity worship with subjective well-being among members of the JKT48 fan community in Sidoarjo using a quantitative correlational design. Results Findings from multiple linear regression indicate that social support and celebrity worship each show positive and significant associations with subjective well-being, both individually and jointly, accounting for 23.8% of variance. Additionally, male fans exhibit higher levels of celebrity worship than female fans. Novelty The study contributes new empirical evidence by focusing specifically on a regional idol fandom community that has not previously been examined in relation to subjective well-being. Implications These results suggest that adaptive engagement in fandom, supported by interpersonal connections, is linked to favorable psychological outcomes, highlighting the importance of balanced parasocial attachment and community support for mental health within fan cultures. Highlights: Interpersonal backing within the fan community is positively associated with life satisfaction and emotional states. Strong attachment to idols corresponds with higher psychological appraisal scores among participants. Male participants demonstrate greater levels of idol fixation compared with female participants.
