Accurate forecasting of global horizontal irradiance (GHI) is critical for optimizing solar power plant (SPP) output, particularly in tropical locales where solar potential is high yet underutilized due to forecasting challenges. This research aims to enhance GHI prediction in one of the major cities of Indonesia, where existing models struggle with the area’s natural climate unpredictability. Our analysis harnesses a decade of data 2011-2020, including GHI, temperature, and the Sky Insolation Clearness Index, to calibrate and compare these methodologies. We evaluate and contrast the exponential smoothing method versus the more complicated artificial neural network (ANN). Our findings reveal that the ANN method, notably its fourth iteration model with 12 input and hidden layers, substantially outperforms exponential smoothing with a low error rate of 1.12%. The use of these methodologies forecasts an average energy output of 252,405 Watt for a solar panel with specification 15.3% efficiency and 1.31 m2 surface area throughout the 2021 to 2025 timeframe. The work offers the ANN method as a strong prediction tool for SPP development and urges a further exploration into more advanced forecasting methodologies to better harness solar energy.

Career uncertainty and unpreparedness of Vocational High School students in the face of the world of work are often associated with career choice factors (career choice). This causes many students who are not confident in choosing available job opportunities and some even choose not to work or become unemployed. This study aims to identify the factors that influence students' career decisions. This study applied the systematic literature review methodology to articles published in foreign journals. The researchers applied predetermined search parameters to locate ten pertinent articles published between 2019 and 2021. The study concluded that it is essential to recognize the factors that influence career decisions. It is crucial to assist students in concentrating more on the job search process and obtaining their desired positions. Employability, as determined by personal traits such as a proactive personality, self-reported education, personal preferences, performance expectations, days worked, industry experience, and years of study, was the most significant factor, followed by social status and prior work experience. This research also has educational and professional applications. Advisors who develop the personal potential of graduates can assist students and job seekers in adopting and exploring career strategies.

The convergence of artificial intelligence, digitalization, and social media has exposed the insufficiency of functional digital literacy as an educational outcome, intensifying attention to Critical Digital Literacy (CDL) as a construct concerned with the ideological and structural logics of digital platforms rather than mere operational use. CDL scholarship nonetheless remains fragmented and lacks a stable, shared taxonomy of its dimensions. This study reports a systematic literature review, following the PRISMA 2020 protocol, of CDL in educational contexts. A Scopus search yielded 130 records, narrowed to 73 after automated screening and to 49 after a stringent CDL-focus eligibility criterion. Qualitative designs dominate the corpus (~55%), followed by conceptual work (~31%), while validated quantitative measurement remains rare (four studies). Inductive synthesis identifies eight recurring CDL dimensions, spanning critical-analytical, socio-political, ethical, identity-based, productive, and civic concerns. None of the 49 included studies directly addresses vocational (VET) teacher education, despite vocational teachers' need to combine technical fluency with critical disposition. Five gaps are identified, concerning measurement instruments, the functional-versus-critical divide, affective dimensions, institutional barriers, and generative AI, with future directions proposed. The synthesis is a necessary step toward a dedicated CDL framework for pre-service vocational teachers.

The effective development of a Mobile-Based Assessment (MBA) depends on studentsÃ¢â‚¬â„¢ acceptance. The aim of this paper was to examine the determinant factor of studentsÃ¢â‚¬â„¢ behavioral intention to use mobile-based assessment. Data were collected from 105 second grade students of a vocational high school through an online survey questionnaire. Partial Least Squares (PLS) was used to test the measurement and the structural model. Results showed Perceived Ease of Use as the strongest direct predictor of Behavioral Intention to Use, followed by Perceived Usefulness. Content and Mobile Self-Efficacy only has an indirect effect. These four variables explain 51.3 percent of the variance of Behavioral Intention to Use.

Digital competence frameworks for teachers have proliferated, but whether their critical, reflective dimension has been examined among technical and vocational education and training (TVET) instructors remains uncharacterized. This scoping review characterized the methodological approaches, conceptual operationalizations, and evidence gaps in peer-reviewed research on critical digital literacy (CDL) among TVET instructors. Following Joanna Briggs Institute guidance and reported per PRISMA-ScR, Scopus was searched on 3 July 2026 using a Population-Concept-Context strategy, restricted to English-language, peer-reviewed literature from 2013–2026. Eligible sources were charted against a framework combining bibliographic, PCC, and methodological data items. Eighty sources met the eligibility criteria. Results included sources concentrated in Western, Northern, and Southern Europe (30.0%) and Southeast Asia (27.5%, including Indonesia at 22.5%), with smaller shares from East Asia, Eastern Europe/Central Asia, and other regions. Quantitative survey designs accounted for roughly half of charted approaches, while qualitative, configurational, and computational designs were comparatively rare. Nine concept-operationalization categories emerged, with an explicit critical-reflective or ethical dimension reported in only 11.2% of sources. An evidence gap map identified 22 of 54 (40.7%) concept-by-context combinations with no charted source, most notably critical-reflective framing paired with Southeast Asian settings. Research on CDL among TVET instructors relies heavily on a single methodological mode and has not yet reconciled structured competence frameworks with the construct’s critical-reflective dimension, particularly outside Europe. Priority directions include region-specific research on critical-reflective CDL in Southeast Asia, a dedicated CDL-specific instrument, and continued tracking of the emerging artificial-intelligence-related sub-theme.
