User-Centered Design for a Multi-Role Academic Support System in Higher Education
Full text linkEffective academic support is a critical component of student success in higher education. As institutions increasingly adopt student-centered learning models, academic counseling emerges as a key mechanism to provide guidance and address individual learning needs. Despite its importance, the counseling process often suffers from structural limitations. Lecturers face heavy workloads that constrain their ability to offer personalized support, while counseling records are typically fragmented and difficult to track. This study aims to design and develop a multi-user system to streamline academic advising and student progress monitoring. The platform incorporates four essential functions: academic scheduling, counseling engagement, performance tracking, and study plan records. It is intended to serve a range of users, including students, faculty advisors, academic staff, and institutional leaders, by facilitating timely and data-informed decision-making. To ensure the system aligns with user needs, a User-Centered Design (UCD) methodology was applied. Focus group discussions were conducted with stakeholders across various roles, including students, lecturers, program heads, deans, and academic staff. The insights were translated into functional requirements, flowcharts, information architecture, and user interface design. The paper also discusses the iterative design process, highlights challenges encountered during development, and offers recommendations for institutions seeking to implement integrated academic support systems
Kompleksitas Notaris dalam Penerapan Prinsip Mengenali Penguna Jasa
Full text linkNotary profession is inherently vulnerable to being exploited by clients seeking to conceal the proceeds of Money Laundering and the financing of Terrorism. Therefore, notaries are designated as reporting parties who are obligated to implement the Know Your Customer (KYC) Principle. This principle requires notaries to conduct identification, verification, and ongoing monitoring of their clients. This research is a normative legal study employing a descriptive approach. The method used to analyze the issues is normative approach. This study aims to analyze the complexity of the application of Know Your Customer principle by notaries and the legal protection for notaries as reporting parties in efforts to prevent money laundering crimes. Based on the findings, it is evident that notaries, as reporting parties, continue to encounter various obstacles in the application of the Know Your Customer principle. Furthermore, to prevent notaries from being misused as intermediaries for the commission of Money Laundering and Terrorism Financing crimes, it is necessary to strengthen notaries capacity through continuous education, enhanced regulatory guidelines, and the support of a more integrated data verification system in collaboration with relevant institutions and a shift from conventional identification methods toward a due-diligence mechanism that utilizes advanced technologies to address modes of operation involving artificial-intelligence–based manipulation, deepfake identity fraud, and crypto-mixer transactions. This transformation is essential to ensure that the notary’s obligations in preventing Money Laundering and Terrorist Financing can be carried out in a more coherent, effective, and compliant manner with the evolving Anti-Money Laundering and Counter-Terrorist Financing regime.

EFEKTIVITAS STORY ACTING DALAM MENGAJARKAN MAGIC WORDS PADA ANAK USIA 5-6 TAHUN [THE EFFECTIVENESS OF STORY ACTING IN TEACHING THE MAGIC WORDS TO CHILDREN AGED 5-6 YEARS]
Full text linkChildren aged 5-6 were found to show impolite behavior, such as using harsh words because they are confused and yet accustomed to speaking politely. Difficulties in teaching polite expressions arose due to children’s limited focus, low interest, and tendency to forget the material. This study examined the effectiveness of story acting in teaching magic words to children aged 5-6. The aim was to improve children’s knowledge of magic words so they could communicate more polite with others. This study used one group pre-test post-test design, involving 11 children. The results showed significant improvements in the use of the words “sorry” (p=.008), “thank you” (p=.034), and “excuse me” (p=.018). However, no significant improvement occurred for “please” (p=.079). Furthermore, overall knowledge of magic words was not retained after a seven-days delay. These results indicate that story acting effectively enhances children’s understanding of “sorry”, “thank you”, and “excuse” though consistent reinforcement is essential to support understanding.

Accuracy of Mammography and Ultrasonography in Differentiating Benign and Malignant Breast Lesions Based on Histopathology at MRCCC Siloam Semanggi Hospital
Full text linkBackground:
Breast cancer is the most common malignancy in women. Early detection improves survival. Mammography is the gold standard for women over 40, while ultrasonography is commonly used in younger women with dense breasts. To compare the diagnostic accuracy of mammography and ultrasonography in differentiating benign and malignant breast lesions using histopathology as the Gold standard.
Methods:
This cross-sectional analytic study included 91 patients who underwent mammography, ultrasonography, and histopathological confirmation at MRCCC Siloam Semanggi Hospital. Diagnostic parameters including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, and area under the curve (AUC) were calculated. Statistical analysis used McNemar’s test and ROC curve analysis based on Hanley & McNeil’s method, with p < 0.05 considered significant.
Result:
Ultrasonography demonstrated higher sensitivity (98.4%) and NPV (92.3%) than mammography (96.7% and 88.9%), indicating better ability to rule out malignancy. Mammography showed higher specificity (53.3% vs. 40.0%) and PPV (80.8% vs. 76.9%), reflecting better performance in identifying benign lesions. Overall accuracy was slightly higher for mammography (82.4%) compared to USG (79.1%). The AUC for mammography was 0.750 (95% CI: 0.630–0.870), while USG had an AUC of 0.692 (95% CI: 0.565–0.819). Overlapping confidence intervals indicated no statistically significant difference in diagnostic accuracy between the two modalities (p > 0.05).
Conclusions:
Mammography and ultrasonography both demonstrated high diagnostic performance with complementary strengths. Mammography provided higher specificity and PPV, while USG offered superior sensitivity and NPV. Given the small difference in accuracy and overlapping AUC confidence intervals, no significant difference was found between the two modalities. Combined use of mammography and USG may improve diagnostic accuracy in clinical practice
Diagnostic Accuracy of Coronary Artery Calcium Scoring in Detecting Significant Coronary Artery Stenosis Compared with Invasive Coronary Angiography
Full text linkBackground:
Coronary artery disease (CAD) remains a leading cause of mortality, emphasizing the importance of early non-invasive diagnostic strategies. This study evaluated the diagnostic accuracy of coronary artery calcium scoring (CACS) in detecting significant coronary stenosis, using invasive angiography as the reference standard.
Methods:
Sixty-three patients who underwent both CACS and quantitative coronary angiography were retrospectively analyzed. The mean total CACS was 684.1 ± 1030.8, and significant stenosis (≥70%) was most prevalent in the left anterior descending artery (92.1%).
Result:
Spearman’s analysis revealed positive correlations between CACS and angiographic stenosis in the right coronary artery (ρ = 0.338, p = 0.007), left anterior descending artery (ρ = 0.492, p = 0.001), and left circumflex artery (ρ = 0.314, p = 0.012). Receiver operating characteristic (ROC) analysis demonstrated moderate-to-good diagnostic performance, with area under the curve (AUC) values of 0.699 for RCA, 0.769 for LAD, and 0.690 for LCX.
Conclusions:
These findings indicate that CACS can serve as a reliable, low-cost, and non-invasive modality for preliminary screening and risk stratification of CAD, particularly in identifying patients who may benefit from invasive coronary angiography
Association Between Ultrasound-Derived Fat Fraction (UDFF) Values and Metabolic Syndrome Laboratory Parameters in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)
Full text linkBackground:
Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), formerly known as Non-Alcoholic Fatty Liver Disease (NAFLD), is highly prevalent worldwide and is strongly associated with metabolic syndrome and its related conditions such as diabetes mellitus and hypertension. Without early detection and intervention, hepatic steatosis can progress to hepatic inflammation, fibrosis, cirrhosis, and even hepatocellular carcinoma (HCC). This study aims to evaluate the relationship between ultrasound-derived fat fraction (UDFF) values and laboratory parameters of metabolic syndrome in MASLD, particularly liver enzymes, lipid profile, and glycemic profile, as well as to determine the optimal UDFF cut-off value for detecting metabolic syndrome risk in Indonesian patients.
Methods:
A cross-sectional study was conducted on 96 patients who underwent UDFF and laboratory assessments including liver enzymes (SGOT/AST, SGPT/ALT), lipid profile (total cholesterol, HDL, LDL, triglycerides), and glycemic profile (HbA1c, fasting blood glucose). Data analysis included bivariate-multivariate correlation and ROC analysis.
Result:
The distribution of UDFF (%) was as follows: normal ≤6% (27.1%; n=26), mild >6–15% (37.5%; n=36), moderate >15–25% (21.9%; n=21), and severe >25% (13.5%; n=13). UDFF showed a moderate positive correlation with SGPT (ρ=0.370; p<0.01) and triglycerides (ρ=0.380; p<0.01), and a weak negative correlation with HDL (ρ=−0.221; p<0.05). A UDFF threshold of 14% was able to predict abnormal SGPT levels and elevated triglycerides.
Conclusions:
UDFF shows a significant correlation with laboratory parameters of metabolic syndrome in MASLD, confirming its potential as an accessible, effective, efficient, non-radiative, and non-invasive imaging modality. These findings support the central role of radiology in the early detection and therapeutic monitoring of MASLD and metabolic syndrome, as well as in preventing disease progression from hepatic steatosis to inflammation, fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Large-scale multicenter validation is required to optimize these findings

Prognostic Significance of Hypoalbuminemia in Transcatheter Aortic Valve Implantation Patients: A Systematic Review and Meta Analysis of Diagnostic Test Accuracy
Full text linkckground:
Calcific aortic stenosis is common in older adults, and TAVR has expanded treatment to patients with high comorbidity and frailty. Serum albumin is an inexpensive marker that reflects inflammation, nutrition, and physiologic reserve, but its prognostic performance in TAVR needs clearer quantification.
Methods:
We performed a PRISMA/PRISMA-DTA–guided systematic review and diagnostic test accuracy meta-analysis of studies evaluating pre-procedural hypoalbuminemia in adults undergoing TAVR/TAVI. PubMed, Embase, and Scopus were searched from inception to 18 January 2026. Hierarchical models were used to pool sensitivity and specificity for 30-day mortality, and a random-effects model pooled hazard ratios for time-to-event mortality. Risk of bias was assessed using PROBAST.
Result:
Ten studies met inclusion criteria. Definitions of hypoalbuminemia varied (most commonly <3.3–3.5 g/dL). For predicting 30-day mortality, pooled sensitivity was 47.7% (95% CI 35.5–59.9) and pooled specificity was 76.0% (95% CI 62.9–89.2), indicating better rule-in than rule-out performance. Across studies reporting time-to-event outcomes, hypoalbuminemia was associated with higher mortality (pooled HR 1.15, 95% CI 1.03–1.29). PROBAST ratings were generally low risk for participants, predictors, and outcomes, with some concerns in the analysis domain.
Conclusions:
Pre-procedural hypoalbuminemia is a practical risk marker in TAVR patients, showing moderate specificity for early mortality and a consistent association with worse survival, supporting its use in peri-procedural risk stratification
Pengajaran Disiplin Gereja berdasarkan pengakuan-pengakuan Reformed
No full textChurch discipline is a sensitive topic because it is directly related to the holiness of believers’ lives within the church. Various theological angles have emphasized the importance of a proper understanding and faithful practice of church discipline. However, a comprehensive exploration of church discipline based on the Reformed confessions has not yet been sufficiently developed. Therefore, this paper aims to explore the doctrine of church discipline as articulated in the Reformed confessions, with particular attention to the Belgic Confession, the Heidelberg Confession, and the Westminster Standards. This study employs a dialectical and analytical approach to examine the teaching of church discipline within the Reformed traditions. The exploration of these confessional documents demonstrates that church discipline is not merely a corrective measure but an essential ecclesial practice. It serves to preserve the holiness and purity of the church, uphold doctrinal faithfulness, and reflect the church’s identity as the body of Christ. Thus, church discipline is understood as a vital means through which the church faithfully lives out its calling before God and the world
