Hospitals as health service providers must know how the quality of service they provide can give satisfaction to patients. Competition between hospitals is getting tougher and sharper so that every hospital is required to enhance its competitiveness by trying to provide satisfaction to all of its patients. Service quality will be considered satisfactory, if the perception exceeds expectations; Service quality will be considered good or adequate if it is in line with expectations, and will be considered bad if the service is bad or not good enough. The purpose of this study was to determine the effect of service quality seen from various dimensions, namely tangibles, responsiveness, reliability, assurance, and empathy on patient satisfaction at the Special Dental and Oral Hospital in Bandung. This literature review uses articles in published Connected Papers in 2017-2022, 108 articles. The results of the 5 articles show that service quality and patient satisfaction are directly proportional, if the service quality is good then customer satisfaction will be good and if the service quality is bad then the level of patient satisfaction is also bad.

Tabular-based clinical risk prediction models are extensively applied in medical decision support systems; however, two major challenges often reduce their reliability: predictions that contradict basic clinical logic and poorly calibrated probability outputs that weaken threshold-based decision making. This study investigates explainable binary risk prediction using the processed Cleveland subset of the UCI Heart Disease dataset as a public clinical benchmark. A lightweight and CPU-efficient pipeline is proposed by employing an XGBoost classifier integrated with monotonic constraints on clinically relevant features, followed by probability calibration through post-hoc methods, including Platt scaling, temperature scaling, and isotonic regression on a separate validation set. Model performance is assessed in terms of discrimination capability using AUROC, AUPRC, F1-score, sensitivity, and specificity, while probability reliability is evaluated using ECE and Brier score metrics. A monotonicity audit is also conducted through counterfactual feature sweeps to measure violation rates. In addition, the model is applied for risk stratification into low-, medium-, and high-risk categories with corresponding event-rate reporting. The findings demonstrate that isotonic regression improves probability reliability without degrading discrimination performance. Furthermore, the monotonicity audit reveals no observed violations for constrained features. Overall, the integration of monotonic constraints and probability calibration produces more decision-ready risk estimates for threshold-based clinical decision support while maintaining transparency through SHAP-based analysis.

Writing articles in this journal aims to describe the service quality of the Trans Semarang Bus Rapid Transit and its sub parameters which include descriptions tangibles, reliability, responsiveness, assurance, dan empaty.

This study aims to analyze the RCM (Reliability Centered Maintenance) and MVSM (Maintenance Value Stream Mapping) strategies implemented by PT. XYZ in machine maintenance at the Sabroe Line. RCM is used to reduce equipment failures and ensure that each physical item or system is functioning as intended. Meanwhile, MVSM is used to identify waste in maintenance activities and perform repair analysis. The research method used is qualitative research with a case study approach. Data was collected through observation, interviews and analysis of related documents. The results of the research show that PT. XYZ has implemented the RCM and MVSM strategies effectively in engine maintenance at the Sabroe Line. RCM implementation helps to reduce machine failure and increase machine reliability. Meanwhile, MVSM helps identify and overcome waste in maintenance activities. In conclusion, the RCM and MVSM strategies are effective approaches in engine maintenance at the Sabroe Line. This research provides a better understanding of the importance of a planned and structured maintenance strategy in improving engine performance. The recommendation for future research is to involve more departments and measure the impact of RCM and MVSM strategies on overall operational productivity and efficiency.

Monitoring applications for filariasis treatment have been developed to overcome the problem of elephantiasis or filariasis, one of which is the lack of monitoring during the distribution of elephantiasis medicines.
