This study aims to simulate the M/M/1 queueing system using Python through a Modeling and Simulation approach supported by the Discrete-Event Simulation (DES) method. The objective of the research is to analyze key performance indicators of queueing behavior, including arrival time, service time, waiting time, queue length, and server utilization. The methodology employs DES, which models system behavior based on discrete events such as customer arrivals, service initiation, and service completion. The simulation generates stochastic arrival and service times using Poisson and exponential distributions, respectively. The results indicate that the DES-based M/M/1 simulation accurately reflects theoretical queueing behavior, showing increases in waiting times and queue lengths when arrival rates approach service rates, while server utilization corresponds to system load intensity. The findings demonstrate that DES is an effective approach for analyzing queue performance and can be extended to more complex models such as multi-server systems, priority queues, and predictive simulations using artificial intelligence.

This study aims to analyze the capital market reaction to the groundbreaking event of the new capital city (IKN) on the stock prices of property and construction sector companies listed on the Indonesia Stock Exchange (IDX). This research employs a quantitative approach using the event study method with an observation period of 11 days, consisting of 5 days before (t-5), the event day (t), and 5 days after (t+5) the event. The sample includes property and construction sector companies that were actively traded during the observation period. Data analysis was conducted using the Paired Sample t-test through SPSS to examine differences in Abnormal Return (AR), Cumulative Abnormal Return (CAR), and Trading Volume Activity (TVA) before and after the event. The results show that there is no significant difference in AR and TVA, but there is a significant difference in CAR, indicating that the market reacted cumulatively to the groundbreaking IKN information. These findings support the semi-strong form of market efficiency theory, suggesting that the market requires time to fully reflect information into stock prices.

This community service activity aims to enhance the understanding of high school graduates regarding the architect profession, educational pathways, and the legal requirements needed to become a professional architect according to the guidelines of the Indonesian Institute of Architects (IAI). The socialization event was held online on November 27, 2025, featuring two professional IAI architects as speakers and attended by 97 participants.

The culture produced in the cultural industry has shifted from merely possessing artistic value to prioritizing economic value. One strategic element that can be utilized to support the development of the cultural industry is the organization of events. Event management plays a strategic role in the cultural industry, ensuring the successful transformation of cultural ideas into real experiences that have economic value while strengthening social meaning. Cultural events often serve as platforms to showcase local cultural heritage, traditions, and creativity to a wider audience, both domestically and internationally. This study examines the influence of the event on enhancing perceptions of the cultural sector using a quantitative methodology. The sample used in this study was 70 respondents. Data collection was carried out by asking respondents to complete a questionnaire relating to their experience attending the cultural event and their assessment of the image as a cultural tourism destination. SPSS was used to examine the information collected from the questionnaire. The results show that the Event variable has a significant influence on the Cognitive Image (CK), Affective Image (CA), and Overall Image (CO) of the destination. The t-test shows that the relationship between Event and the three image dimensions has a p-value <0.05, which indicates a strong and significant influence. Events designed with informative, emotional, and interactive aspects in mind will significantly contribute to the formation of the overall image. In a practical context, the implication is that event organizers need to ensure the quality of the holistic experience to continuously strengthen the overall image.

The rise of social media has made TikTok one of the platforms where public discussions quickly develop, especially when dealing with issues involving public figures. Cases of infidelity often receive strong reactions, and many users express their emotions through comments that spread widely and shape public conversation. This study aims to examine the emotional expressions of netizens in responding to an infidelity case involving a public figure on TikTok, particulary on the account @nyatamedia. A descritive qualitative approach was applied, using documentation and content analysis to identify the forms and meanings of netizen comments contain a range of emotions such as anger, dissapointment, disgust, empathy, sadness, fear, sarcasm, and social criticism. Anger and dissapointment show rejaction of the infidelity, while empathy and sadness reflect concern for the affected party. The comments contain personal views and criticism related to social conditions, especially those connected to public perceptions of marriage. Based on these findings, social media appears to serve as a space where people express their feelings and opinions about events that attract public attention.

This study examines the stock market reaction to the Christmas and New Year holidays by analyzing abnormal return and trading volume activity for companies consistently listed in the LQ45 Index during 2021–2023. Using a quantitative causal approach and an event study design, the research observes market behavior within a 10 day estimation window and a 10 8day event window surrounding the holiday period. The findings show that abnormal return exhibits limited but notable reactions, with a significant decline observed before the holiday, indicating that investors tend to reduce risk exposure prior to market closure. After the holiday, significant movements still appear, but they remain negative, suggesting that investor activity and confidence have not fully recovered. In contrast, trading volume activity does not show significant differences either before or after the holiday, implying that changes in prices are influenced more by sentiment and price adjustments rather than shifts in trading intensity. These results indicate that the Indonesian capital market demonstrates characteristics of a semi-strong form efficiency, where public information such as national holidays is largely anticipated and absorbed by the market.

This study aims to analyze the reaction of the Indonesian capital market to the establishment of the Danantara Investment Management Agency (BPI) as a new financial institution formed by the government in 2025. Using a quantitative approach through the event study method, this study measures the abnormal return of the Composite Stock Price Index (JCI) around the date of the announcement of Danantara's establishment, namely in the observation period from January 31 to April 17, 2025. The analysis results show that the market reacted significantly negatively on the day of the announcement (t₀) with an abnormal return of -0.78 percent and a p-value of 0.05, while on other days around the event, no significant reaction was found. This indicates that the market responds quickly to public information, but the impact is temporary. In the long term, the cumulative abnormal return (CAR) shows a significant negative trend, reflecting market pressure and investor caution regarding Danantara's existence. These findings are in line with the semi-strong form of market efficiency theory and show that investor confidence is highly dependent on the transparency and governance of state financial institutions. Overall, the results of this study confirm that the establishment of Danantara has not had a sustainable positive impact on the Indonesian capital market.

Break-even point analysis is conducted to assess a company's performance, providing insight into the importance of financial bookkeeping and economic analysis. It can also be used as a consideration for entrepreneurs in making decisions related to sales activities. Break-even point refers to a concept used in financial planning to determine the level of sales or revenue required to cover all costs and expenses, resulting in zero profit or loss. The PKM training is conducted in three stages: the preparation stage, where an initial survey is conducted to determine participants' knowledge of the Break-Even Point (BEP) calculation. The implementation stage, where training is provided to all fishermen on the BEP calculation. The monitoring and evaluation stage, where the implementation of the BEP calculation is monitored and the fishermen's understanding of the break-even point is evaluated. Break-even point (BEP) training is expected to improve business owners' and crew members' understanding of the BEP concept and enable them to apply BEP calculations in decision-making.

This study investigates the clinical handover process as a critical component of patient safety and healthcare service quality in hospital settings. Inconsistent communication, incomplete documentation, and the absence of standardized procedures were identified as major problems contributing to communication failures and potential adverse events. The objective of this research was to develop and test a structured and effective handover model that could improve communication accuracy and documentation reliability among healthcare professionals. A mixed methods design was employed, consisting of a qualitative phase (in-depth interviews, observations, and document analysis) to explore real-world handover practices, followed by a quantitative phase using a pretest–posttest design to evaluate the effectiveness of the proposed model. The study proposes an integrated handover model based on SBAR-IM (Situation, Background, Assessment, Recommendation, Intervention, Monitoring) strengthened by Quality Control (QC) and Mutual Confirmation (MC) mechanisms. The findings demonstrate a significant improvement in handover quality after implementation, with communication scores increasing from 74 to 84.5 and documentation scores improving from 48.3 to 63.0 (p < 0.05). Qualitative results further revealed reduced communication errors, improved clarity of clinical information, and enhanced interprofessional collaboration. This study concludes that the proposed SBAR-IM–based QC–MC model is effective, practical, and suitable for improving patient safety and healthcare service quality in hospital environments.

This study aims to evaluate the performance of Digilib services at Amikom University Purwokerto using the Information Technology Infrastructure Library (ITIL) version 3 framework in the Service Operation domain. The phenomenon underlying this study is the indication of a decline in the operational effectiveness of Digilib services as seen from the inconsistency of system performance, access speed, and limited service features. This study uses an evaluative quantitative approach by collecting data through a questionnaire compiled based on five main processes in the Service Operation domain, namely Event Management, Incident Management, Request Fulfillment, Problem Management, and Access Management. The research respondents were library staff directly involved in the management and operation of Digilib services. Data were analyzed using a process maturity model (Process Maturity Model) to assess service capabilities based on a scale of 0–5. The results of the analysis indicate that the overall maturity level of Digilib services is at Level 4 (Managed Process), with an average value of 4.07. This indicates that the operational process has been controlled and measured through certain performance indicators, although there are still opportunities for improvement towards Level 5 (Optimized), especially in the Request Fulfillment and Problem Management domains. These findings contribute to strengthening IT service governance in the higher education sector and provide strategic recommendations for improving automation, system integration, and data-driven service management. The implications of this research encourage the development of policies to improve the quality of digital services and serve as a reference for further research on ITIL implementation in academic settings.

This literature study evaluates the accuracy of the Slope Mass Rating (SMR) method for coal mine slope stability in Indonesia through a systematic descriptive synthesis of 25 empirical studies from 2020 to 2025. The objectives of the study were to identify the level of SMR prediction accuracy, factors affecting the method's performance, and modifications required for local Indonesian conditions. The research method involved a systematic search with inclusion criteria for empirical studies reporting SMR and/or Safety Factor (SF) values ​​for coal mines and associated slopes in Indonesia. Quantitative analysis showed a range of reported SMR values ​​between 41 and 96 with a median of 72, while SF values ​​ranged from 1.137 to 4.09 for normal operational conditions. The synthesis results indicated that SMR provides a consistent stability classification for initial slope design and failure mode identification (planar, wedge, toppling), with historical validation showing a correlation of up to 91.23% between SMR-based hazard zoning and actual field events in some cases. Key limitations include dependence on discontinuity data quality, sensitivity to groundwater conditions and tropical weathering, and variation in the interpretation of adjustment factors F1-F4. Modifications such as NAAF23 and integration with numerical modeling have been shown to improve prediction reliability. It is recommended that coal mining practitioners combine SMR with kinematic analysis and limit equilibrium modeling as standard operating procedures, and develop adjustment factors specific to Indonesian geological conditions. Further research should focus on standardizing parameter reporting and cross-site quantitative validation to enable more robust statistical meta-analyses.  

The Bemeteng tradition in Cempaka Hamlet, Tebas Sungai Village, Tebas District, Sambas Regency, is a form of community mutual cooperation in helping to organize wedding parties, especially for families who experience economic limitations. The implementation of the event involves extended family, neighbors, and local residents, while the main responsibility remains with the host. This tradition reflects the value of togetherness, social solidarity, and a culture of helping in community life. This study uses a qualitative method with a historical and sociocultural approach. Data was collected through observations, interviews with traditional leaders, religious leaders, and communities, and documentation studies. The analysis was carried out through data reduction, data presentation, and conclusion drawing to understand the dynamics and sustainability of the Bemeteng tradition during the period 2001–2025. The results of the study show that the implementation of Bemeteng began with a call from the community by the sarok about one week before the party. The Head of the Hamlet opened the activity by conveying the host's wishes, followed by the division of tasks such as collecting aid, kitchen work, and welcoming guests, then closed with prayers and a simple banquet. This tradition developed from a simple self-help pattern (2001–2010), underwent revitalization (2011–2019), restrictions during the pandemic (2020–2021), and has been active again since 2022 with digital support and cultural policies. The community views Bemeteng as an important heritage that strengthens unity and is in line with the values of deliberation and helping in Islamic teachings.

Plasma Cell Leukemia (PCL) is a rare lymphoproliferative disorder characterized by the proliferation of malignant plasma cells in the bone marrow and their presence in the peripheral blood. PCL is classified into primary plasma cell leukemia (pPCL), which occurs de novo without a prior history of multiple myeloma, and secondary plasma cell leukemia (sPCL), which arises in association with relapsed or refractory multiple myeloma. A 58-year-old woman presented with right hip pain that had been ongoing for four months. The pain progressively worsened, limiting her ability to move her leg and eventually causing significant difficulty in walking. She also experienced bilateral lower limb weakness and an unintentional weight loss of 10 kg over the same period. The patient denied any history of trauma. Physical examination revealed pallor without signs of bruising or spontaneous bleeding. Laboratory findings showed severe anemia (Hb 6.5 g/dL), leukocytosis (24,100/µL), thrombocytopenia, an elevated erythrocyte sedimentation rate, and 25% plasma cells on peripheral blood smear. Bone marrow aspiration demonstrated 40% infiltration by plasma cells. Based on the patient’s clinical presentation, physical examination, and laboratory findings, the diagnosis is consistent with primary Plasma Cell Leukemia.

Fifth grade students' consistently poor reading comprehension abilities, which impeded their overall academic development and participation in language acquisition, served as the driving force for this study. Using a comic assisted problem based learning (PBL) model, the study, which involved 39 students at SDN Purwamekar, aimed to improve learning activities in order to increase teacher and student participation and, eventually, improve fifth grade students' reading comprehension skills. By using comic strips to illustrate issues, this creative method made learning more engaging and accessible for younger students. In order to enable iterative improvements, the study was conducted over two cycles using classroom action research technique. Only 25% of students (eight people) successfully completed the learning objectives in the first cycle, according to preliminary findings, while 75% (24 students) failed, suggesting difficulties with student motivation and comprehension. This led to changes like improving comic material and fostering more cooperative conversations. Significant progress was seen by the second cycle, with 30 students meeting the completion criteria and only four falling short of the objectives, indicating improved engagement and skill growth. In conclusion, the comic assisted PBL model effectively boosted reading comprehension skills among fifth grade students. The research underscores the value of integrating visual aids and problem solving in education, offering practical insights for teachers to create more dynamic classrooms. Nonetheless, factors like time constraints and resource availability warrant further exploration to ensure sustainable implementation in diverse educational settings.

The implementation of patient safety culture in hospitals remains a significant challenge, often leading to adverse events. Establishing a strong patient safety culture requires effective interprofessional collaboration among healthcare professionals to deliver patient-centered care. However, factors such as organizational distrust and job dissatisfaction continue to hinder collaborative efforts and negatively affect the quality of care and patient safety outcomes.This study aims to examine the influence of organizational trust and job satisfaction on patient safety culture, with interprofessional collaboration serving as an intervening variable at MP hospital.  This quantitative associative research used a causal approach involving 93 inpatient nurses as respondents. Primary data were obtained through questionnaires using an ordinal scale based on a 4–1 Likert scale. Data processing employed the three-box method, and data analysis was conducted using Structural Equation Modeling (SEM).The results revealed that organizational trust, job satisfaction, and interprofessional collaboration simultaneously and partially influence patient safety culture. Moreover, interprofessional collaboration was found to mediate the relationship between organizational trust, job satisfaction, and patient safety culture.The study concludes that enhancing patient safety culture can be achieved by strengthening organizational trust and job satisfaction through effective interprofessional collaboration. Hospitals should develop supportive systems that foster care and concern among staff, enhance conflict management, improve performance appraisal mechanisms, and promote open, effective communication across all professional groups involved in patient care. These strategies can create a safer, more collaborative, and high-quality healthcare environment

Power transformer theft, a pervasive issue disrupting critical infrastructure, necessitates the development of cost-effective and energy-autonomous security solutions. This paper presents the design and implementation of a detection-focused anti-theft framework that integrates a Raspberry Pi Zero W, camera module, and passive infrared (PIR) motion sensors powered by a solar system for continuous monitoring. The system is designed for remote, off-grid deployment, utilizing a headless Raspberry Pi powered by a 5V solar panel and power bank to ensure energy autonomy. Upon motion detection, captured images are processed on the edge device using OpenCV’s Haar Cascade classifier, optimized for upper-body detection to minimize false positives and verify human presence. Captured images are processed locally on the edge device using OpenCV’s Haar Cascade classifier to confirm human presence before an alert is sent to the mobile application, emphasizing real-time operation and low latency. Once an intrusion is confirmed, the images are saved locally and uploaded via the Secure File Transfer Protocol to a custom-developed Android application. The app provides a dedicated remote monitoring interface, enabling secure file transfer and system access, while providing users with immediate notifications and image management capabilities. The system emphasizes low power consumption, real-time operation, and low deployment cost. Tests over 200 triggered events under varied environmental conditions achieved 90% detection accuracy with an average latency of 4.5 s. Solar autonomy was maintained for approximately 24 h under normal operation. It is concluded that the integration of solar power, edge computing of images, and mobile monitoring provides a feasible, scalable, and financially viable framework for securing transformers, especially in resource-constrained environments.

In life as a congregation and as servants of God, we cannot escape conflict within the church. Sometimes, conflict is inevitable within a church.
