This study aims to examine the impact of implementing the Core Tax Administration System (CORETAX) on the effectiveness of tax reporting at PT Yekape Surabaya. CORETAX is an integrated digital tax administration system introduced by the Directorate General of Taxes in early 2025. Using a descriptive qualitative approach, data was collected through semi-structured interviews with two key informants directly involved in the company's tax reporting process. The findings indicate that CORETAX positively affects tax reporting efficiency, system integration, and data transparency. All types of taxes can now be reported through a single platform, replacing the previous manual and segmented applications. However, challenges remain, particularly related to human resource adaptation, system navigation, and technical disruptions during the initial phase. PT Yekape addressed these challenges through internal training and interdepartmental coordination. The study concludes that the success of CORETAX implementation heavily depends on organizational readiness—both technical and human—and the strategic role of internal leadership in supporting the digital transition.

Chronic Kidney Disease (CKD) or chronic kidney failure is a condition that occurs due to a decrease in the kidney's ability to maintain balance in the body so that hemodialysis therapy is needed to replace the kidney function. Hemodialysis therapy can cause various physical effects and mental conditions of patients so that it can affect the patient's quality of life. Objective : to determine the relationship between anxiety levels and quality of life of CKD patients undergoing hemodialysis at Lakipada Hospital. Research Method : the research design used is quantitative research with a Cross Sectional approach, using a " saturated sampling" sampling technique with a sample size of 40 respondents. The independent variable is the level of anxiety and the dependent variable is the quality of life. Data were analyzed using the Chi-Square statistical test at a significance level of ? <0.05. Research Results : it was found that there was a relationship between anxiety levels and quality of life in CKD patients undergoing hemodialysis with a p-value = 0.000. Conclusion : there is a relationship between anxiety levels and quality of life in CKD patients undergoing hemodialysis.

This study aimed to evaluate the antioxidant activity and total phenolic content of methanolic extract and column chromatography fractions of Lantana camara L. leaves. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging method, while total phenolic content was determined by the Folin–Ciocalteu assay. The methanolic extract exhibited strong antioxidant activity (IC₅₀ = 23.25 mg/L) and a total phenolic content of 2927.4 mg/L gallic acid equivalents (GAE). Fractionation yielded nine fractions (A–I), among which Fraction E demonstrated the highest antioxidant activity (IC₅₀ = 11.58 mg/L) and the greatest phenolic content (5200 mg/L GAE). A strong negative correlation (R² = 0.9485) was observed between phenolic content and IC₅₀ values, indicating that phenolic compounds are the major contributors to the antioxidant activity. These findings highlight L. camara leaves as a promising natural source of antioxidants and support their potential application in the development of functional foods and plant-based pharmaceutical formulations.

The presence of LGBT individuals (Lesbian, Gay, Bisexual, and Transgender) in society has raised complex discussions, especially when viewed from the perspectives of Islamic law and human rights. Islamic teachings generally view same-sex relations and gender transitions as actions that deviate from the moral and natural order established by religious texts. In contrast, the human rights framework emphasizes individual dignity, personal freedom, and the right to non-discrimination, regardless of sexual orientation or gender identity. This article seeks to explore the intersection of these two perspectives, not to provoke conflict, but to offer a balanced understanding rooted in empathy, justice, and social awareness. Using a qualitative normative approach, this research examines Islamic legal sources, national regulations, and international human rights documents. The study finds that while Islamic law maintains clear normative boundaries, there is still room for inclusive dialogue and respectful engagement, especially in multicultural societies like Indonesia. Bridging these two frameworks requires not only legal analysis but also cultural sensitivity and ethical responsibility.

Semaphore is a communication method used to send and receive messages by utilizing flags, paddles, sticks, bare hands, or gloves. Semaphore signaling is commonly used in scouting activities (Pramuka). However, novice scouts often face difficulties in accurately recognizing semaphore gestures. Although guidebooks are available, errors may still occur, especially when learning independently. To address this issue, a gesture detection system using the Multi-Layer Perceptron (MLP) method and MediaPipe framework is proposed, which aims to evaluate the accuracy of MLP and MediaPipe in detecting semaphore poses. To assess the performance of the MLP model, a Confusion Matrix is used to analyze the number of correct and incorrect predictions and generate metrics such as accuracy, precision, recall, and F1-score. The evaluation results show that the system successfully recognized 122 poses correctly, achieving an accuracy of 93.84%, precision of 93.84%, recall of 100%, and an F1-score of 96.80%. Based on these results, the system is considered sufficiently accurate and can be used as an interactive learning tool to recognize semaphore codes, particularly in scouting activities.
