Chronic kidney disease (CKD) is a progressive and irreversible decline in kidney function that, if left untreated, can lead to serious complications. Ultrasonography (USG) is a widely used imaging modality for detecting CKD, yet its interpretation remains highly dependent on the radiologist’s expertise. This study aims to develop a CKD detection system using a convolutional neural network (CNN) on kidney ultrasound images based on estimated glomerular filtration rate (eGFR), and to evaluate the system’s performance. This research employed a research and development (R&D) approach with an experimental design. The dataset consisted of kidney ultrasound images from CKD and non-CKD patients with corresponding eGFR values. The methodology included image preprocessing, CNN model training, and accuracy evaluation using classification metrics. The results demonstrated that the developed CNN model achieved a total accuracy of 97% on internal test data and 95.8% on external validation. The model’s sensitivity reached 100% for the normal category, 91.67% for CKD stage 4, and 90% for CKD stage 5. Specificity exceeded 96% across all categories, with high precision and F1-scores above 94% for all classes. This system has proven to be effective as a diagnostic support tool for automatically detecting CKD through kidney ultrasound imaging. Its advantages lie not only in accurately classifying CKD from USG images but also in correlating the classification results with patients' eGFR values. This provides more precise clinical information and supports appropriate CKD staging and management planning.

The rapid advancement of science and technology requires universities to provide safe, comfortable, and representative learning facilities. One such initiative is the construction of a five-story lecture building at Dr. Soetomo University, designed with a steel structure as an alternative to reinforced concrete. Steel was chosen due to its high tensile strength, uniform material properties, lighter weight, ease of installation, and strong resistance to earthquake loads. This study aims to design a five-story lecture building with a steel structure that meets the requirements of strength, stability, and safety in accordance with applicable standards. The method applied is structural planning based on SNI 1729:2020, SNI 1727:2020, and SNI 1726:2019 using the Load and Resistance Factor Design (LRFD) approach. Structural analysis was conducted with SAP2000 version 2014 through three-dimensional modeling that considers geometry, material properties, loading, and placement. The results show that the selected steel profiles for beams, columns, and connections are capable of supporting the combination of dead loads, live loads, and seismic loads with safe performance. The maximum stress remains below the allowable limit, and the deflection values do not exceed the permitted deviation. These findings confirm that steel provides efficiency in dimensions and materials while offering practicality and earthquake resistance, and the design produced can serve as a useful reference for future multi-story building projects in earthquake-prone regions.

Introducion The performance of nurses is a critical determinant of hospital service quality, influenced by multiple factors such as workload, competence, and supervision. This study aimed to analyze the effect of workload and nurse competence on nurse performance with supervision as a moderating variable at X  Hospital. Methods The research employed a quantitative approach with a causal survey design. Data were collected using structured questionnaires distributed to 176 nurses and analyzed through Structural Equation Modeling (SEM) with SmartPLS 4.0. Result The findings revealed that both workload and competence significantly influenced nurse performance, with competence showing a strong positive effect. Workload was also found to have a significant effect on supervision, and nurse competence significantly enhanced supervision quality. However, supervision did not function as a moderating factor in the relationship between workload and nurse performance, nor between competence and nurse performance. Similarly, supervision itself was not significantly associated with nurse performance. The coefficient of determination showed that workload, competence, and supervision jointly explained 60% of nurse performance, while the remaining 40% was influenced by other unmeasured factors. Conclusion, workload and competence are proven to be direct determinants of nurse performance, whereas supervision in its current form does not enhance these effects. Hospital management should therefore focus on optimizing workload distribution, strengthening nurse competencies through continuous training, and reformulating supervision methods to be more participatory and supportive. These strategies are expected to improve the quality and effectiveness of nursing services and ensure sustainable improvements in hospital performance outcomes.

This study examines the role of organizational citizenship behavior (OCB) as a moderator in the relationship between employee engagement, job satisfaction, and employee performance at the Tarokan District Office in Kediri Regency. The research focuses on analyzing how these variables interact and influence each other within the organizational context. The findings indicate that employee engagement has a significant impact on employee performance. This suggests that when employees are more engaged in their work, they tend to exhibit higher levels of performance. Similarly, job satisfaction also significantly influences employee performance. Employees who are satisfied with their work environment and tasks tend to perform better in their roles. However, the study reveals that organizational citizenship behavior does not significantly influence employee performance. This implies that while OCB is often considered a valuable aspect of employee behavior, it does not directly affect how well employees perform their tasks in this particular setting. Additionally, employee engagement does not significantly affect organizational citizenship behavior, indicating that engaged employees do not necessarily engage in extra-role behaviors like helping others or going beyond job requirements. The research also shows that job satisfaction does not have a significant effect on organizational citizenship behavior, which suggests that employees’ satisfaction with their work does not automatically lead to behaviors that contribute to the broader success of the organization. Furthermore, neither employee engagement nor job satisfaction significantly influences employee performance through organizational citizenship behavior, indicating that OCB does not serve as an effective moderator in these relationships. In conclusion, the main factor in improving employee performance is organizational citizenship behavior does not play a significant moderating role in this dynamic at the Tarokan District Office.

The Student Evaluation of Lecturers (EDOM) at the Faculty of Engineering, Universitas Dr. Soetomo has historically been conducted via Google Forms and processed manually, resulting in slow response times, repetitive recap procedures, and insufficiently documented reporting validity. This study aims to design, build, and evaluate a web-based EDOM system using the Prototype Model (MODEL PROTOTYPE) to improve data collection efficiency, recap accuracy, and the effectiveness of feedback for teaching quality assurance. The development method comprises requirements elicitation with the Quality Assurance Unit through a review of SPMI documents and brief interviews, architectural and interface design (Laravel, MVC pattern, and MySQL), staged prototyping, and rapid iterations based on stakeholder feedback until functional conformity is achieved. The resulting system provides authentication and role-based authorization (Admin, GPM, Lecturer, Student), odd/even period management, a question bank employing a Likert scale, anonymous questionnaire submission, score recap per lecturer and per category (pedagogical, professional, personal, social), dashboard visualizations, and report export to support governance needs. Functional evaluation was conducted through black-box testing on core scenarios (login, period scheduling, submission, recap, and export) and indicated conformance to specifications. User acceptance evaluation employed the Technology Acceptance Model (TAM) to examine perceived usefulness, perceived ease of use, attitude toward use, and behavioral intention; the results indicate positive acceptance and potential for operational adoption. Practically, the prototype approach accelerates requirement alignment, reduces the risk of mis-specification, and facilitates change control, while the Laravel-based implementation supports maintainability, role-based access security, and further feature development. The study is limited to a single faculty; future work may include SSO integration, audit trails, and longitudinal, cross-semester analytics for more comprehensive monitoring of lecturer performance.

This study analyzes the potential use of solar cells as a renewable energy source on the MV SARI INDAH. With the increasing demand for energy and the negative environmental impacts of fossil fuels, solar cells provide a promising eco-friendly alternative. The research focuses on developing a prototype system to charge batteries using solar power, converting DC power into AC for ship operations.

This study aims to analyze the reward system in improving the performance of educators at State Islamic Senior High Schools (Madrasah Aliyah) in Jambi Province. The research focuses on the reward mechanism, its implementation, and the factors that determine its effectiveness in improving educator performance. This study uses a descriptive qualitative approach with data collection techniques through observation, in-depth interviews, and documentation. The research locations include three madrasas: MAN 1 Tanjung Jabung Barat, MAN 1 Kota Jambi, and MAN 1 Merangin. The results show that the implemented reward system includes financial rewards (such as incentives and allowances) and non-financial rewards (such as certificates, training, and job promotions). Rewards have been shown to play an important role in improving educator motivation, discipline, loyalty, and performance. However, the implementation of the reward system has not been optimal due to several obstacles, such as budget constraints, lack of transparency in assessments, and the incompatibility of the types of rewards with the needs of educators. On the other hand, madrasas that implement the reward system appropriately and fairly show an increase in the quality of educator work, marked by increased participation, work performance, and professional responsibility. This study concludes that an effective reward system is one that has clear criteria, is transparent, and responsive to the needs of educators. Recommendations are directed to madrasah principals and the Ministry of Religious Affairs to build a strong culture of appreciation and allocate an adequate reward budget to improve the quality of education in madrasahs.

This study is motivated by the importance of employee performance as a key factor in achieving organizational goals. Optimal performance is significantly influenced by various factors, one of which is workload and the working environment. An unbalanced workload can hinder productivity, while a non-conducive working environment can reduce comfort and work enthusiasm. Therefore, this study aims to analyze the impact of workload and the working environment on employee performance at PT Kampung Bali Indah Jakarta Pusat, both partially and simultaneously. This study uses a quantitative approach with a saturated sample of 52 respondents. Data collection was conducted using questionnaires, and the data were analyzed using SPSS version 25. The analysis included validity and reliability tests, classical assumption tests, multiple linear regression, t-tests, F-tests, and the coefficient of determination. The results show that workload has no significant partial effect on employee performance. This indicates that, although excessive workload can affect performance, other factors play a more dominant role in influencing employee performance. In contrast, the working environment has a positive and significant impact on employee performance. A conducive work environment provides comfort for employees to work more effectively and efficiently. Simultaneously, both workload and the working environment significantly affect employee performance, contributing 73.5%. This means that more than 70% of employee performance is influenced by these two factors, while the remaining performance is influenced by other factors not covered in this study. These findings suggest that to improve employee performance, the company should enhance the working environment to better support employee comfort and productivity. On the other hand, workload management should also be adjusted to remain optimal without adding excessive pressure on employees.

This study aims to analyze the influence of inflation and interest rates on banking profitability as measured through Return on Assets (ROA) in conventional banks listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. The research was conducted from April to May 2025 with a quantitative approach and multiple linear regression analysis methods. The data used are secondary data obtained from the annual financial statements of eight conventional banks as well as macroeconomic data from Bank Indonesia, which were selected through the purposive sampling method. The data analysis process includes descriptive statistics, classical assumption test, t test, F test, and determination coefficient. The results of the study show that partially, neither inflation nor interest rates have a significant effect on ROA. This is shown by the value of t calculating inflation of 0.049 < t table 2.02619 with a significance of 0.961 > 0.05, and t calculating interest rates of 1.163 < t table 2.02619 with a significance of 0.252 > 0.05. However, simultaneously, inflation and interest rates have a significant effect on ROA, as shown by the calculated F value of 8.698 > F table 3.25 and the significance of 0.001 < 0.05. These findings indicate that although individual macroeconomic variables do not have a significant impact, together they have an influence on banking profitability. This research contributes to policy makers and banking industry players in understanding macroeconomic dynamics on banks' financial performance.
