The rapid growth of digital marketplaces has fundamentally transformed consumer decision-making processes by intensifying price transparency, product comparability, and information exposure. In highly competitive marketplace environments, consumers are frequently confronted with numerous product alternatives and dynamic pricing structures, which shape how they evaluate options and ultimately decide to purchase. This study examines the effects of product variety and price perception on consumers’ purchase decisions in the context of ROSCA tumbler products sold on the Shopee marketplace. Using a quantitative explanatory approach, this research employs a survey-based design to analyze the relationships among variables and to estimate their relative effects through multiple linear regression analysis. Data were collected from 100 respondents who had previously purchased ROSCA tumblers on Shopee, selected using purposive sampling based on predefined criteria. The research instrument consisted of 15 Likert-scale items measuring product variety, price perception, and purchase decision. Data analysis included descriptive statistics, instrument validity and reliability testing, regression assumption diagnostics, and hypothesis testing using both partial (t-test) and simultaneous (F-test) procedures. The findings reveal that product variety has a positive and significant effect on purchase decisions, indicating that consumers are more likely to finalize purchases when they perceive product options as sufficiently diverse, relevant, and comparable. Price perception also exerts a positive and significant influence and demonstrates a stronger relative effect compared to product variety. This result underscores the central role of perceived price fairness, competitiveness, and value-for-money in shaping purchase decisions within transparent and highly competitive marketplace settings. Simultaneously, product variety and price perception explain a substantial proportion of variance in purchase decisions, highlighting their combined importance as key marketing stimuli. These findings contribute to the literature on digital consumer behavior by providing empirical evidence from a specific marketplace–product context and offer practical implications for sellers and brand managers in optimizing assortment design and pricing strategies to enhance conversion rates in online marketplaces

This study aims to analyze the implementation of gender-based public policy through the Child-Friendly School Program at SDN 01 Bendosari, Plantungan District, Kendal Regency. This research employed a descriptive qualitative approach using in-depth interviews, observation, and documentation as data collection techniques. Data analysis was conducted using the public policy implementation model proposed by George C. Edwards III, which emphasizes four key variables: communication, resources, implementers’ disposition, and bureaucratic structure. The findings reveal that the implementation of the Child-Friendly School policy at SDN 01 Bendosari has been carried out through an integrative approach by incorporating child-friendly principles into existing school programs and culture. Effective policy communication and positive implementers’ disposition, particularly among teachers and the school principal, have supported the implementation process. However, limited financial resources remain a major obstacle to fully optimizing the policy implementation. This study concludes that successful public policy implementation depends not only on regulatory frameworks but also on resource availability, implementers’ commitment, and institutional capacity to adapt policies to local conditions.

Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, life-threatening mucocutaneous reactions characterized by extensive epidermal necrolysis and mucosal involvement. The entities represent a clinical continuum distinguished by the extent of epidermal detachment (SJS <10% body surface area [BSA], SJS/TEN overlap 10–30%, TEN >30%). Most cases are drug-induced, making early culprit-drug withdrawal and structured supportive care the cornerstones of management. Immunopathogenesis is primarily mediated by drug-specific cytotoxic T cells and NK cells through granulysin, Fas–Fas ligand, and perforin/granzyme pathways, with emerging roles of necroptosis and candidate biomarkers such as RIP3 and galectin-7. Diagnosis relies on timely recognition of the characteristic painful erythematous/targetoid lesions, Nikolsky/Asboe–Hansen signs, multi-site mucositis, accurate BSA assessment, and early severity scoring (e.g., SCORTEN) to guide referral and monitoring. Systemic immunomodulators (corticosteroids, cyclosporine, IVIg, anti-TNF agents) have variable evidence; thus, individualized selection and early multidisciplinary care particularly ophthalmologic involvement are essential to reduce acute mortality and long-term sequelae.

The high unemployment rate in Indonesia highlights the importance of enhancing work readiness among young people from an early educational stage.

These findings suggest that learning motivation, communication skills, and parental support play a crucial role in improving students’ readiness to enter the workforce. The results of this study are expected to provide practical implications for schools and parents in strengthening students’ preparation for the world of work

Global social inequality remains one of the fundamental challenges in the contemporary world economic system. The dominance of capitalist economic structures, which emphasize growth and capital accumulation, has proven effective in stimulating economic progress; however, it has simultaneously widened the gap between wealthy and disadvantaged groups at both national and global levels. Meanwhile, socialist economic systems that prioritize income equalization continue to face limitations related to efficiency and innovation. This article aims to examine the role of Islamic economics as an alternative economic framework capable of addressing the challenge of global social inequality. The study employs a qualitative descriptive approach through a literature review of classical and contemporary sources related to global economic systems. The findings indicate that Islamic economics offers a more balanced paradigm by integrating principles of distributive justice, ethical values, and social responsibility within economic activities. Instruments such as zakat, infaq, sadaqah, waqf, along with the prohibition of riba and other exploitative economic practices, serve as essential mechanisms for reducing social inequality. Therefore, Islamic economics holds significant potential as both a normative and practical solution for promoting sustainable global economic justice.

This study investigates the determinants of capital structure within the healthcare industry, focusing on the influence of asset structure, profitability, and company size. Given the capital-intensive nature of healthcare—characterized by significant investments in medical technology and infrastructure—understanding how these firms balance debt and equity is critical for financial sustainability and operational growth. Using a quantitative approach, this research analyzes a panel dataset of healthcare companies listed on the Indonesian Capital Market from 2018 to 2023. Furthermore, the capital structure is quantified by the debt-to-equity ratio. Meanwhile, asset structure, profitability, and company size are measured by the ratio of fixed assets to total assets, return on assets, and the natural logarithm of total assets, respectively. Moreover, the data are analyzed using multiple linear regression, supported by the classical assumption testing. As a result, asset structure has a significant positive impact on capital structure, aligning with the static trade-off theory. Conversely, profitability demonstrates a significant negative relationship with capital structure, supporting the pecking order theory. Finally, company size positively affects capital structure, indicating that larger firms have greater access to debt financing. These findings suggest that healthcare managers should optimize their asset utilization and internal reserves to maintain an efficient capital structure that supports long-term healthcare delivery and investor confidence.

This study aimed to analyze differences in body composition among adult women across three regions with distinct sociocultural and environmental characteristics: Baduy Luar (rural–traditional), Salatiga (semi-urban), and Kota Bambu (urban). Using a cross-sectional design, the study involved 268 participants and assessed total body fat, visceral fat, subcutaneous fat, and skeletal muscle mass using the OMRON HBF-370 analyzer. Significant differences were observed across most body composition parameters (p < 0.001). Women living in the urban area exhibited the highest levels of total fat, visceral fat, and subcutaneous fat, reflecting the influence of urbanization and sedentary lifestyle on adiposity. Conversely, women in the rural–traditional community demonstrated the highest skeletal muscle mass across all body regions, consistent with their physically demanding daily activities and traditional dietary patterns. These findings highlight the substantial role of environmental context in shaping metabolic health and cardiometabolic risk. Targeted public-health interventions—such as structured physical-activity promotion and nutrition education in urban populations, and preservation of active lifestyles in rural communities—are recommended. Longitudinal studies are warranted to clarify causal pathways and further characterize metabolic determinants.

This study aims to analyze the implementation of affective learning strategies in Akidah Akhlak subjects to enhance students' self-control at MTs Muhammadiyah 02 Purbalingga.

This socialization activity highlights the importance of collaboration among parents, teachers, and the surrounding community to ensure sustainable character development in children.

  Abstract. This study aims to develop and evaluate an artificial intelligence–based expert system to support fault diagnosis in Air Handling Units (AHUs). Early fault identification in AHU systems is often constrained by reliance on technician experience, which may lead to inconsistent diagnostic outcomes. The proposed system is intended to provide a consistent, explainable, and practical decision-support tool to assist maintenance personnel, particularly less-experienced technicians, in identifying AHU faults accurately. Methodology: The research adopts a rule-based expert system approach using forward chaining inference. Knowledge acquisition was conducted through structured interviews with experienced HVAC technicians and supported by technical documentation. The resulting knowledge base consists of observable symptoms, diagnostic rules, and corresponding corrective actions. The system was implemented as an Android-based mobile application to enable direct field usage. System validation was performed using real operational fault scenarios, with expert diagnoses serving as the reference standard. Findings: Evaluation results indicate full agreement between the system-generated diagnoses and expert assessments across all tested scenarios. This demonstrates that the proposed system is capable of producing accurate and consistent diagnostic outcomes within its defined knowledge domain. Implications: The system operates using deterministic rules without incorporating uncertainty modeling or probabilistic reasoning. Additionally, validation was limited to a finite number of real-world scenarios, which may affect generalizability to broader AHU configurations. Practical implications: The expert system can be utilized as a practical diagnostic aid in routine AHU maintenance, improving response time, diagnostic consistency, and technician training effectiveness. Originality: This study contributes a mobile-based, explainable expert system specifically tailored for AHU fault diagnosis, emphasizing practical deployment and rule transparency rather than data-intensive learning models.

This study aims to conduct an in-depth analysis of the psychological journey of the character Rangga Raja in the novel 0 MDPL by Nurwina Sari. The main focus of the study is to identify the inner conflicts experienced by the protagonist as well as the dynamics of the personality structure consisting of the Id, Ego, and Superego that shape his psychological development throughout the storyline. This research employs a literary psychology approach using a qualitative descriptive method, conducted through a literature review and document analysis of the novel text as the primary data source. The findings indicate that Rangga Raja experiences complex emotional conflicts resulting from past trauma, experiences of loss, and failures in romantic relationships. These conditions are reflected through the tensions and interactions between the Id, Ego, and Superego within himself. The process toward the “zero point” (0 MDPL) is interpreted as a symbol of an identity crisis phase as well as a stage of self-reconstruction, in which the protagonist undergoes processes of reflection, self-acceptance, and openness to change. In addition, Rangga’s interactions with other characters, such as Andini, La Nina, and Nadia G. Sahara, play an important role in his psychological recovery and healing process. This study confirms that the novel 0 MDPL represents a profound reflection on human psychological dynamics, the search for identity, and the gradual process of inner healing.

This study aims to conduct a Systematic Literature Review (SLR) regarding the influence of career development on organizational commitment. Based on the analysis of various scientific articles, career development is an important approach in human resource management, which focuses on improving employees’ skills, enthusiasm, and readiness to face job challenges and promotion opportunities. On the other hand, organizational commitment refers to the emotional connection that employees have with their workplace, which includes aspects of emotional attachment, obligation, and enduring bonds. The results of the systematic literature review indicate that many previous studies have found a strong and positive correlation between career development and organizational commitment. Workers who are aware of support for their career development, including training programs, mentoring, or predetermined career paths, generally show a higher level of dedication to their organization. Furthermore, various studies have shown that career development can also have an indirect effect on organizational commitment through mediating factors such as job satisfaction, work motivation, and employee performance. However, several studies have shown that career development does not always have a significant impact on organizational commitment, particularly in organizations without a structured career system or when employees have negative perceptions of career opportunities. These varying results highlight the existence of contextual factors that influence the relationship between variables. Overall, this study offers in-depth insights into the significance of career development as a strategic factor in enhancing organizational commitment, along with suggestions for organizations and future researchers conducting similar studies.

Banda Aceh City has high vulnerability to tsunamis due to its coastal location directly facing the sea and being situated in an active tectonic zone. This study evaluates the spatial distribution of tsunami risk and assesses coastal conditions as disaster mitigation efforts using a mixed-method approach that combines quantitative analysis based on Geographic Information Systems (GIS) and qualitative analysis through field surveys and expert assessments. Three beaches were selected as study locations: Ulee Lheue Beach, Syiah Kuala Beach, and Alue Naga Beach, with risk assessment calculated using the formula Risk = (H × V) / C according to the BNPB framework and overlay techniques in GIS to create risk distribution maps. Coastal condition evaluation focused on coastal vegetation and protective coastal structures assessed using an ordinal scale of 1–5. Results show that Ulee Lheue Beach has the highest mitigation capacity with a score of 64.5% (good category), Syiah Kuala Beach reaches 57.5% (fairly good), while Alue Naga Beach has the lowest score of 28.3% (poor). Correlation analysis yielded a coefficient of r = 0.97, indicating a very strong positive relationship between coastal vegetation and protective coastal structures. Therefore, the study recommends strengthening mitigation strategies through improved protective infrastructure and optimization of coastal vegetation functions, particularly in high-risk areas, to reduce tsunami impacts in the future.
