Abstract:External evidence can make retrieval-augmented generation (RAG) more informative, yet retrieved passages also provide a path for adversarial instructions to enter the model context. We examine that path in an English-Indonesian…
onesian RAG system and track cross-lingual indirect prompt injection separately at retrieval, reranking, and generation. The experiment starts from 75 semantic items and evaluates every item in eight query/body/payload language combinations, for 600 paired trials. Qwen3-Embedding-0.6B and BGE-M3 produce top-20 candidate sets, BGE-reranker-v2-m3 reduces each set to five documents, and Qwen3-0.6B answers from the resulting context with either a standard prompt or an explicit trust-boundary prompt. Statistical uncertainty is estimated by resampling semantic items, and paired binary outcomes are modeled with generalized estimating equations. Poison documents reached the top 20 in 80.50% of Qwen trials and 37.67% of BGE-M3 trials (odds ratio 6.94, 95% CI 4.53-10.63). Top-five exposure was 18.50% and 16.17%, respectively. Standard end-to-end attack success was 6.33% for Qwen and 6.00% for BGE-M3; boundary-aware prompting lowered both rates to 1.33%, with no canary false positives. The results indicate that multilingual RAG security depends on several linked stages rather than generation alone.
Abstract:This study examines how leadership and work-life balance influence employee performance directly and indirectly through employee engagement at the Fisheries Service of Central Maluku Regency. A descriptive quantitative,…
causal-correlational design was applied to the entire population of 49 employees using total sampling. Data were analyzed through descriptive statistics, path analysis, and Sobel tests to estimate direct, indirect, and mediating effects. The findings show that leadership significantly affects employee engagement (beta = 0.582; p < 0.001), while work-life balance also has a significant, although smaller, effect on engagement (beta = 0.129; p = 0.005). Employee engagement strongly affects performance (beta = 0.942; p < 0.001). In contrast, the direct effects of leadership (beta = 0.034; p = 0.613) and work-life balance (beta = -0.008; p = 0.756) on performance are not significant. Sobel testing confirms that employee engagement mediates the effect of leadership on performance (p = 0.00015) and the effect of work-life balance on performance (p = 0.03). The model explains 92.4% of the variance in performance. The study's novelty lies in demonstrating, within a local public-sector context, that leadership and work-life balance improve performance primarily by strengthening employee engagement rather than through direct effects. These findings imply that public organizations should prioritize engagement-oriented leadership and work-life policies to achieve sustainable employee performance.
Abstract:Stunting is a chronic nutritional problem influenced by various direct and indirect factors, including maternal knowledge of nutrition, maternal education, and family income. This study aimed to determine the relationship…
p between family characteristics and the incidence of stunting among children aged 24–59 months in Nagari Sinuruik, within the working area of Talu Public Health Center. This study used a quantitative descriptive-analytic method with a cross-sectional design. The study was conducted from February to August 2024, with data collection carried out from June 26 to 30, 2024. The study population consisted of 85 children aged 24–59 months, with a sample of 46 respondents selected using random sampling. Data were collected using questionnaires and analyzed using the Chi-Square test. The results showed that 26 toddlers (56.5%) experienced stunting, 28 respondents (60.9%) had poor nutritional knowledge, 28 respondents (60.9%) had a lower educational level, and 24 respondents (52.2%) had low family income. There were significant relationships between maternal knowledge and the incidence of stunting (p=0.007), maternal education and the incidence of stunting (p=0.012), and family income and the incidence of stunting (p=0.009). The study concluded that maternal knowledge, maternal education, and family income were associated with the incidence of stunting among children aged 24–59 months. Public health center staff are expected to continue monitoring the nutritional status of toddlers and improve nutrition education for mothers, adolescents, and prospective brides and grooms.
Abstract:Digital transformation has become a strategic priority for organizations seeking to enhance competitiveness and achieve sustainable performance in dynamic business environments. This study examines the effect of digital…
leadership on sustainable performance through the mediating role of employee agility within the context of human capital development. A quantitative explanatory approach was employed using survey data collected from employees involved in digital transformation initiatives. Data were gathered through a structured questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to assess the direct and indirect relationships among the proposed constructs. The findings indicate that digital leadership significantly enhances employee agility by fostering adaptability, continuous learning, and responsiveness to technological change. Employee agility was found to have a strong positive effect on sustainable performance, suggesting that agile employees contribute substantially to organizational resilience, innovation capability, and long-term effectiveness. Furthermore, employee agility partially mediates the relationship between digital leadership and sustainable performance, demonstrating that the influence of leadership on sustainability outcomes operates largely through workforce adaptability. These results highlight the critical role of human capital development in digital transformation and provide empirical evidence that sustainable organizational performance can be achieved when digital leadership is effectively translated into agile employee behavior. The study contributes to the growing literature on digital transformation and human resource management by offering an integrated framework that links leadership, employee capabilities, and sustainability-oriented organizational outcomes.
Abstract:Food security in the low-carbon transition is increasingly shaped by industrial decarbonization, environmental restoration, and circular supply-chain coordination, yet these domains are often modeled as separate sustainability…
bility agendas. This study addresses the gap by developing a governance-centered structural equation model that links sustainable industrialization, sustainable remediation, circular supply chain governance, and food-security outcomes. Using the available 455-response dataset, the empirical test operationalizes industrialization intensity (IND) as a proxy for sustainable industrialization, digital-institutional capability (DIC) as a proxy for circular governance capability, and social-economic resilience (SER) as a proxy for food-system security. Confirmatory factor analysis supports the measurement model: standardized loadings range from .778 to .849 for IND, .804 to .835 for DIC, and .800 to .843 for SER; CR values range from .901 to .914; AVE ranges from .646 to .681; and model fit is acceptable (chi-square/df = 2.108, CFI = .961, TLI = .951, RMSEA = .049, SRMR = .038). The SEM results show that IND significantly predicts DIC (beta = .537, p < .001), DIC predicts SER (beta = .424, p < .001), and IND retains a direct effect on SER (beta = .337, p < .001). The indirect effect is significant (beta = .228, 95% CI [.178, .282]). The article contributes a cautious, data-grounded framework for analyzing food security as a governance-mediated outcome of low-carbon industrial transition.
Abstract:This study aims to analyze the influence of paid social media advertising and the quality of digital marketing content on the purchase decision of the BuatMudah e-course, both directly and indirectly through customer trust…
st as a mediating variable. The background of this study is based on the decline and fluctuations in BuatMudah e-course sales amidst the growth of the EdTech industry and increasing competition in the educational market for content creators. This study used a quantitative approach with a survey method. Primary data were obtained by distributing questionnaires to 355 BuatMudah e-course customers. The research instrument was designed based on indicators of paid social media advertising, digital marketing content quality, customer trust, and purchase decisions. Data were analyzed using Structural Equation Modeling (SEM) and the Sobel test to examine the mediating role. The results show that paid social media advertising has a positive and significant effect on customer trust, with a path coefficient of 0.72 and a calculated t-value of 16.17. The quality of digital marketing content also has a positive and significant effect on customer trust, with a path coefficient of 0.75 and a calculated t-value of 14.41. Furthermore, paid social media advertising had a positive and significant effect on purchasing decisions with a path coefficient of 0.25 and a calculated t-value of 4.35. Meanwhile, the quality of digital marketing content had a positive and significant effect on purchasing decisions with a path coefficient of 0.14 and a calculated t-value of 2.31. Customer trust was shown to have a positive and significant effect on purchasing decisions with a path coefficient of 0.39 and a calculated t-value of 5.03. The Sobel test results indicate that customer trust mediates the effect of paid social media advertising on purchasing decisions and also mediates the effect of digital marketing content quality on purchasing decisions. Thus, purchasing decisions for the BuatMudah e-course are determined not only by advertising effectiveness and content quality, but also by the ability of these two digital marketing stimuli to build customer trust.

ing housing purchase decisions. This study aims to analyze the mediating role of brand image in the influence of product quality, price, and location on millennial cluster property purchase decisions in Bogor Regency. A quantitative approach was employed using a descriptive and verificative research design. Data were collected through questionnaires distributed to 220 millennial consumers who had experience purchasing or were directly involved in purchasing cluster property in Bogor Regency. The research instrument was measured using a five-point Likert scale and analyzed using structural equation modeling to test direct and indirect effects. The results show that product quality, price, and location have positive and significant effects on brand image. Product quality, price, location, and brand image also have positive and significant effects on purchase decision. Furthermore, brand image partially mediates the effects of product quality, price, and location on purchase decision. These findings indicate that millennial property purchase decisions are shaped by both rational property attributes and psychological trust in developer reputation.
Abstract:This study examines the effect of inflation, interest rates (BI7DRR), and exchange rates (USD/IDR) on stock returns of PT Telkom Indonesia (Persero) Tbk., with the Jakarta Composite Index (IHSG) as an intervening variable.…
e. Using a quantitative explanatory research design, monthly secondary data spanning January 2016 to December 2025 (120 observations) were analysed using Pearson correlation and two-stage path analysis (OLS regression). Results indicate that inflation and exchange rates significantly influence IHSG, while the BI Rate does not. However, neither macroeconomic variables nor IHSG significantly affect Telkom's stock returns either directly or indirectly. The model explains only 2.7% of the variation in stock returns, suggesting that company-specific and sectoral factors dominate return determination. These findings imply that IHSG does not serve as an effective mediating channel between macroeconomic conditions and individual stock returns for Telkom. Investors in the telecommunications sector should prioritise fundamental and sectoral analysis over macroeconomic indicators when making portfolio decisions
Abstract:The purpose of this study is to examine how product quality influences consumers' decisions to buy electric cars in Makassar City, using brand image as a mediating factor. The swift expansion of electric vehicle adoption…
necessitates a comprehensive understanding of the factors influencing customer purchasing behavior in this nascent sector. A quantitative methodology utilizing an explanatory study design was implemented to examine the causal links among the variables. The population comprised consumers who had acquired or utilized electric vehicles in Makassar City, while the precise population size remained unspecified. A purposeful non-probability sampling strategy was employed, resulting in 105 respondents who completed a structured online questionnaire sent using Google Forms. The data were analyzed utilizing SEM-PLS with SmartPLS to investigate both direct and indirect effects among the constructs. The findings demonstrate that product quality positively and significantly impacts purchase decisions, product quality positively and significantly influences brand image, and brand image positively and significantly affects purchase decisions. Additionally, brand image serves as a partial mediator in the correlation between product quality and purchasing decisions. The findings indicate that superior product quality in electric vehicles is more influential in influencing purchasing decisions when it concurrently cultivates a favorable brand image in consumers' perceptions, thus offering strategic insights for manufacturers and distributors in formulating marketing strategies that enhance both product quality and brand image.
