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.

This study aims to analyze tehe effect of profitability and firm size on firm value with capital structure as a mediating variable. The study was conducted on food and beverage sub-sector companies listed on the Indonesia Stock Exchange during 2020-2023. The variables used in this study include Return on Assets (ROA), frim size (SIZE), Dept to Equity Ratio (DER), and Price to Earnings Ratio (PER). Path analysis was applied to test the relationsips. The results show that booth profitability and firm size significantly influence capital structure. Pprofitability and firm size also directly affect firm value. Furthemore, capital structure ppartially mediates the relationship between profitabilitiy, firm size, and firm value. These findings highlight the importance of strategic capital structur management to enhance corporate financial performance and long-term value, especially in the food and beverage sector.

Poromas are benign neoplasms composed of epithelial cells that show tubular differentiation, which arises from the intraepidermal part of the eccrine of the sweat glands. This lesion can resemble melanoma or non melanoma.1,2 Case description We reported a case of eccrine poroma in a man, Mr. ES, 50 years old, with complaints of a lump in the head of the temporal region of the region. On macroscopic examination, a blackish-brown scalp tissue size 2x1x0.5 was received, the surface was uneven, the consistency was springy. Microscopic examination of squamous epithelial coating with round, oval, monotone, smooth chromatin, eosinophilic cytoplasm appear. In the sub-epithelium, there is a mass of tumors consisting of proliferative eccrine glands, in groups forming islands, with cuboidal coatings, with round, oval, monotonous nuclei, fine chromatin, eosinophilic cytoplasm. The stroma consists of fibrous connective tissue and blood vessels. The sebaceous glands, hair follicles and infiltration of lymphocyte cells appear. Discussion and conclusions: Based on the results of histopathological examination, it can be concluded as eccrine poroma. In this case electrosurgery is performed, removal with the help of a carbon dioxide laser, or excision surgery can be performed.

Sustainable development in coastal areas requires collaborative governance involving multiple stakeholders, including government, private sector, and communities. Makassar, as a major coastal city in Eastern Indonesia, faces significant challenges in implementing sustainable development programs in its coastal areas.This study examines the influence of collaborative governance on the success of sustainable development programs in Makassar's coastal areas, with a focus on accountability mechanisms and stakeholder engagement processes.This research employs a mixed-method approach, combining quantitative analysis using Structural Equation Modeling (SEM) and qualitative analysis through in-depth interviews with 150 respondents from government agencies, private sector, NGOs, and local communities. Data were collected from January to October 2024 in four coastal sub-districts of Makassar.The study reveals that collaborative governance significantly influences the success of sustainable development programs (β = 0.687, p < 0.001). Key mediating factors include transparency in resource allocation (β = 0.445, p < 0.01), community participation in decision-making (β = 0.523, p < 0.001), and integrated monitoring systems (β = 0.398, p < 0.05). Effective collaborative governance enhances sustainable development program outcomes through improved accountability, resource efficiency, and stakeholder satisfaction. The findings suggest that formal collaboration frameworks and transparent financial reporting mechanisms are critical success factors.

This study aims to analyze the application of the Zero Based Budgeting (ZBB) method in budget management in 2025 as a strategic step to improve efficiency, transparency, and accountability in public financial governance. ZBB is a budgeting approach that requires each organizational unit to prepare a budget from zero without referring to previous allocations, so that each expenditure must be logically justified based on actual needs and strategic priorities. In the context of increasing fiscal pressures and demands for bureaucratic reform, the relevance of ZBB is increasingly strengthening. Using a qualitative approach through literature studies and policy analysis, this study evaluates the effectiveness, constraints, and prospects of ZBB implementation in various government sectors that are undergoing digital transformation, such as immigration services and public services. The results of the study show that although ZBB is able to improve budget efficiency and build a more responsible work culture, its success is highly dependent on the readiness of human resources, reliable information systems, and strong political support. Therefore, the implementation of ZBB in 2025 needs to be accompanied by systematic training, supporting regulations, and an integrated performance evaluation system to produce a significant impact on better budgeting practices.
