This study examines the transportation management flow at PT Xpresindo Logistik Utama Medan Warehouse and its impact on delivery accuracy. The research method used a qualitative approach through direct observation and interviews with warehouse managers and operational staff. The results showed that the distribution flow from receiving goods from Jakarta to shipping to customers in Medan was quite effective, although it was still dominated by manual systems such as the use of Delivery Notes and Excel records. The use of the Monstra tracking application was not evenly distributed, so fleet movement information was not always updated in real time, especially when demand volume increased at the end of the month. To improve efficiency, the study recommended the implementation of a Transportation Management System (TMS), digitalization of barcode/QR code-based inventory processes, and a Key Performance Indicator (KPI) dashboard to monitor delivery timeliness and fleet utilization periodically.

The implementation of Hospital Management Information Systems (HMIS) has become a strategic imperative to enhance operational efficiency amidst the ongoing global digital health transformation era. This study aims to analyze the determinants of successful HMIS implementation and its impact on service efficiency and patient outcome quality. Employing a narrative review approach with thematic synthesis of literature from PubMed, Scopus, and ScienceDirect databases between 2016-2026, the study evaluates the relationship between technology investment and organizational performance. The synthesis results indicate that while HMIS significantly reduces administrative burdens and medication errors, a "digital paradox" exists where technical efficiency may disrupt interpersonal interactions between healthcare providers and patients if systems are not user-centered. Key success factors include data interoperability (HL7/FHIR standards), human resource readiness, and governance policy support. This study concludes that a patient-centered efficiency model is the fundamental basis for ensuring technology investments yield sustainable added value within the healthcare delivery system.

The planning process was also unsupported by adequate feasibility studies, while weak internal oversight exacerbated tender rigging and fund disbursements without proper verification. This study emphasizes the need for improvements in internal oversight, strengthening control mechanisms, and the implementation of e-procurement systems to enhance transparency and accountability in public procurement.

Intellectual property (IP) protection in higher education institutions has largely been viewed as an administrative requirement focused on documentation and registration volume. This creates a paradox, as increasing research outputs are not matched by adequate legal protection, innovation downstreaming, and societal utilization of research results. Therefore, a reorientation is needed to position IP protection as a strategic instrument for building a fair innovation ecosystem. This community engagement program was conducted in LLDIKTI Region I institutions through presentations, discussions, and strengthening IP center capacity. Activities focused on mapping IP systems, identifying management challenges, and reinforcing a paradigm oriented toward innovation downstreaming and public benefit. Results show improved participant understanding of shifting IP protection from an administrative to a strategic approach. IP is increasingly recognized as a tool for innovation, technology transfer, and institutional competitiveness. This reorientation emphasizes inventor rights protection, fair benefit distribution, and broader public access to innovation within a sustainable and equitable ecosystem.

This research is motivated by the increasingly complex life of global society, characterized by the intensity of intercultural and interreligious encounters and diverse value systems. These interactions often give rise to conflict, intolerance, and moral crises in social life.

This research is driven by Law Number 1 of 2023 concerning Financial Relations between the Central Government and Regional Governments (HKPD), which reclassifies several taxes, including entertainment tax, into the Category of Goods and Services Tax (PBJT). This policy is further regulated by Surabaya City Regional Regulation Number 7 of 2023. This study aims to analyze the contribution of entertainment tax within the PBJT framework toward Surabaya's Local Generated Revenue (PAD) from 2021 to 2023. Using a descriptive quantitative approach, data were collected from the Surabaya City Budget Realization Report (LRA) and other official documents, then processed using RStudio. The results indicate that while entertainment tax realization increases annually, its contribution to Surabaya's PAD remains significantly low, averaging below 2%. This suggests that entertainment tax is not yet a primary source of revenue for the city. Based on these findings, the Surabaya City Government is expected to tighten supervision over entertainment transactions through digital systems to minimize fraud risks and conduct comprehensive data updates on new entertainment venues to maximize tax collection.

This study aims to explore the meaning of service excellence from the perspective of hotel employees at Kinasih Resort Depok, Indonesia. Most existing research on service excellence has focused on guest satisfaction, leaving the subjective experiences of employees as service providers underexplored. This study employs a qualitative approach with a descriptive phenomenological design. Data were collected through in-depth interviews, participatory observation, and documentation from five purposively selected informants across the F&B Service, Housekeeping, Front Office, Human Resources, and management departments. Data analysis followed Moustakas's phenomenological procedure encompassing epoché, horizonalization, theme clustering, and essence description. Findings reveal that employees construct layered meanings of service excellence according to their hierarchical positions: frontline workers emphasize friendliness and responsiveness, supervisors emphasize speed and problem resolution, while management frames it as a holistic service ethos encompassing internal relationships. Emotional labor emerged as an inevitable dimension managed through collaboration, prioritization, and de-escalation strategies. Organizational factors including training systems, communicative leadership, guest feedback-based evaluation, and managerial attention to employee well-being demonstrably shape how employees internalize service excellence values. This study contributes to employee-centered literature on service excellence and offers practical implications for human resource development in resort contexts.

These results provide evidence that FGD was effective not only in evaluating participants’ competencies but also in generating practical solutions to enhance transparent and accountable regional financial governance.

This article examines marriage law within Indonesian customary law communities and its interaction with national legal regulations. In customary societies, marriage is not merely a personal bond between a man and a woman, but a social institution involving extended families and the wider community. The study aims to describe the various forms of customary marriage, the requirements for its validity, and the procedures for legalization, including the recognition of marriages among adherents of indigenous belief systems. This research employs a normative juridical approach using statutory and conceptual analysis based on relevant legal provisions and customary practices. The findings show that customary marriage systems in Indonesia are strongly influenced by kinship structures such as patrilineal, matrilineal, and parental systems, resulting in diverse forms including bridewealth marriage, semenda marriage, independent marriage, mixed marriage, and elopement. The validity of marriage in customary law is closely connected to religious or belief-based rituals and community acknowledgment. Furthermore, developments in national law, particularly Law Number 1 of 1974 on Marriage and Constitutional Court Decision Number 97/PUU-XIV/2016, have strengthened legal recognition for followers of indigenous beliefs in marriage registration. The study concludes that customary marriage law remains relevant and continues to coexist with national law, reflecting Indonesia’s legal pluralism and cultural diversity.

Heating, Ventilating, and Air Conditioning (HVAC) systems often suffer from significant energy wastage due to their inability to adapt to real-time environmental changes, leading to high operational costs. Although Proportional-Integral-Derivative (PID) controllers are widely used for their simplicity and reliability, they struggle to handle the complex dynamics of modern environments, requiring advanced optimization to enhance efficiency. This study aims to optimize PID controllers by integrating the Queen Honey Bee Migration (QHBM) algorithm to improve HVAC performance, energy efficiency, and adaptability. The research method employs an experimental approach that compares the performance of conventional PID controllers with PID controllers optimized using the QHBM algorithm under dynamic environmental conditions. The results show that the PID-QHBM system significantly outperforms the conventional PID system, achieving a rise time of 0.2649 seconds and a settling time of 1.6874 seconds with an almost negligible steady-state error of 9.4991e-08. Although it experiences a slight overshoot of 16.3810%, the system stabilizes quickly and maintains the target temperature efficiently. In contrast, the conventional PID controller exhibits slower response characteristics, with a rise time of 1.3730 seconds, a settling time of 2.5144 seconds, and a larger steady-state error of 0.0361. This study demonstrates that integrating the QHBM algorithm into PID controllers provides a more effective solution for real-time temperature control, offering substantial improvements in energy efficiency and system performance. The findings contribute to advancing intelligent HVAC control systems that can better adapt to environmental variations while minimizing operational costs.

This research is motivated by the existence of legal pluralism in marriage regulations in Indonesia before the enactment of Law Number 1 of 1974 concerning Marriage. During that period, marriage provisions were influenced by various legal systems, namely customary law, Islamic law, and colonial laws such as the Burgerlijk Wetboek, whose application was based on population classification. This condition gave rise to various problems, including legal uncertainty, differing standards for marriage validity, and weak protection of the rights of women and children. Based on these problems, this study aims to examine the development of marriage law in Indonesia, both before and after the enactment of the Marriage Law, and to assess the extent to which these regulations have been able to achieve legal unification and certainty within the national legal system. The method used is qualitative-normative research with a literature study approach through analysis of relevant laws and regulations, historical documents, and scientific literature. The results indicate that before 1974, the marriage legal system was complex and unintegrated, necessitating a comprehensive codification. The process of drafting this law was lengthy and marked by ideological debate and religious considerations. However, an agreement was ultimately reached that accommodated both religious values ​​and state interests. Subsequent developments, including amendments through Law Number 16 of 2019, confirm that marriage law in Indonesia is dynamic in responding to demands for justice, human rights, and gender equality.

The implementation of digital health information systems, such as e-Puskesmas, plays an important role in supporting electronic medical records in primary healthcare facilities. However, technical constraints, including network instability and system integration issues, may affect user satisfaction among healthcare workers. This study aims to analyze healthcare workers’ satisfaction in using e-Puskesmas based on the End User Computing Satisfaction (EUCS) method. This research employed a quantitative analytic approach with a cross-sectional design, involving 35 healthcare workers at Puskesmas Klangenan using total sampling. The variables consisted of five EUCS dimensions, namely content, accuracy, format, ease of use, and timeliness. Data were collected using a structured questionnaire with a Likert scale and analyzed using descriptive statistics and Spearman correlation test. The results showed that user satisfaction was categorized as very satisfied across all EUCS dimensions, with mean scores ranging from 4.11 to 4.47. All EUCS dimensions had a positive and significant relationship with user satisfaction (p < 0.05), with format and ease of use showing the strongest correlations. It can be concluded that the quality of system and information in e-Puskesmas significantly influences healthcare workers’ satisfaction, indicating the need for continuous system development to support optimal healthcare services.
