The reliability of a data center is highly dependent on its air conditioning and cooling system. This research evaluates the existing cooling system of Universitas Krisnadwipayana’s data center using the PPDIOO Network Life-Cycle approach. The study finds that the current cooling system, which relies on AC Split, fails to meet TIA-942 standards, posing significant overheating risks and increasing downtime probability. Observational analysis shows that the cooling distribution is inefficient due to inadequate airflow and the absence of a structured cooling layout. To address these issues, this research proposes an optimized cooling system design that incorporates Computer Room Air Conditioning (CRAC), hot aisle-cold aisle arrangement, and raised floor implementation. The recommended improvements also include installing temperature and humidity sensors for real-time environmental monitoring and implementing N+1 redundancy for enhanced system reliability. These solutions are expected to improve cooling efficiency, reduce energy consumption, and mitigate downtime risks. Future research should focus on evaluating the practical impact of this design by conducting real-world trials and exploring liquid cooling technology as a potential alternative for further efficiency improvements.

Background: Brand loyalty reflects patients' tendency to continue using a hospital's services and recommend them to others. However, the decline in physiotherapy patient visits since the COVID-19 pandemic has affected hospital revenue, while brand image and digital marketing via Instagram are still underutilized. Most previous studies have addressed brand loyalty in general, while specific studies on physiotherapy units are still rare. Although many studies show that SMMA and brand image affect loyalty through brand trust, research specifically examining the role of brand reliability as a dimension of trust in healthcare services is still limited.Objective: This study fills this gap by examining the influence of SMMA, brand image, and brand reliability on brand loyalty in the context of physiotherapy services at Siaga Raya Orthopedic Hospital.Methods: This research uses quantitative methods with a purposive sampling technique on 120 respondents. Data analysis was conducted using Structural Equation Modeling (SEM) with the Partial Least Square (PLS) method. The study develops the SOR (Stimulus-Organism-Response) theoretical framework.Results: SMMA has a significant effect on brand loyalty both directly and through the mediation of brand reliability. In contrast, brand image requires brand reliability mediation to influence loyalty. Brand reliability proved to be an essential element in building patient loyalty.Implications: Hospitals need to design marketing strategies through social media and brand image that are not only attractive but also reflect service reliability to establish long-term relationships with patients.

Signs of danger in the third trimester of pregnancy are important indicators for preventing obstetric complications that can potentially increase the risk of maternal morbidity and mortality. However, the level of awareness and preparedness of mothers in recognizing signs of danger often depends on access to education and the quality of information received during pregnancy. Maternity classes are one of the educational strategies recommended in antenatal care to improve mothers' attitudes and understanding of pregnancy health. This study aims to analyze the effect of antenatal classes on mothers' attitudes toward danger signs in the third trimester at the Galala Inpatient Health Center. This study used a quantitative analytical design with a post-test only design approach. The study sample consisted of 30 pregnant women in their third trimester who were selected using total sampling technique. Data collection was conducted using a closed-ended questionnaire based on a Likert scale that had been tested for validity and reliability (α = 0.82). Data analysis was performed descriptively because the distribution of respondents' attitude scores was homogeneous. The results showed that all respondents (100%) had a fairly positive attitude towards pregnancy danger signs after attending the pregnancy class. These findings indicate that pregnancy classes play a role in increasing mothers' awareness of health risks during pregnancy, although they have not yet reached the optimal attitude category. The conclusion of this study confirms that pregnancy classes contribute to improving maternal attitudes and need to be improved through a variety of educational methods and increased frequency of meetings to support stronger attitude change.

 Election integrity is a key element in ensuring democratic legitimacy, yet election fraud remains a significant threat to this process. This research aims to evaluate the use of Bayesian statistics in detecting anomalies in vote distributions that may indicate potential election fraud. In the context of elections, whose reliability is often questioned, statistical analysis becomes crucial to ensure transparency and credibility in election results. This study uses national election data collected from various polling stations (TPS), focusing on vote distribution per candidate in each TPS. A Bayesian probabilistic model is applied to analyze the observed vote distribution compared to the expected distribution. By using Bayesian inference, researchers can update the probability distribution based on the obtained data, allowing for more accurate anomaly identification. The analysis results show significant deviations in several TPS, where the observed vote distribution exhibits patterns inconsistent with the expected distribution. These anomalies are suspicious as they may indicate manipulation or errors in the vote counting process. The implications of this research suggest that the Bayesian method can be used to improve election transparency and provide a more reliable tool for detecting fraud. The future application of this technique can help increase public trust in election results and support the integrity of the democratic process. This study also recommends further development of the analytical model to expand the scope of anomaly detection and enhance fraud detection accuracy in larger and more complex elections.
