The role of a leader has a relationship with the performance and success of implementing nurses. Effective leaders can influence in various ways with their leadership style. Leaders provide direction and goals to members with their leadership style. Leadership style is able to influence, be smart in encouraging, motivating, and facilitating their subordinates so that their goals are achieved. According to Lippits and K. White, there are 3 leadership styles, namely authoritarian, democratic, and laissez-faire. This leadership style influences the loyalty of a implementing nurse's performance in implementing nursing care which can be seen in the quality of service provided to patients. Quantitative research, correlational design. Cross-sectional approach measuring the independent variable of the ward head's leadership style and the dependent variable of the implementing nurse's performance and the relationship between the ward head's leadership style and the implementing nurse's performance were carried out once at the same time. The results of the research showed that the majority of democratic leadership styles were 116 respondents (81.1%), the performance of the majority of nurses was in the good category as many as 118 respondents (82.5%), and the relationship between the leadership style of the head of the room and the performance of the implementing nurses in the chi square test with a p value of 0.533 > alpha (0.05), then Ho = There is no relationship between the leadership style of the head of the room and the performance of implementing nurses at Santa Elisabeth Hospital Medan. For implementing nurses who still have the performance of implementing nurses in the sufficient category, they should increase their self-motivation to be more responsible in carrying out their duties as nurses which is part of their work profession.

Hospitals have the main responsibility in providing quality, effective, and efficient health services. The performance of the implementing nurse is an important indicator to ensure the quality of service and patient safety. The supervision of the head of the room as part of the managerial function includes planning, organizing, guidance, direction, supervision, evaluation, as well as recording and reporting, all of which are aimed at ensuring that nursing care is carried out according to standards. This study is focused on analyzing the influence of head of room supervision on the performance of implementing nurses in the inpatient room of Wira Husada Kisaran Hospital in 2025. The study used a quantitative approach with a cross sectional design. All 86 implementing nurses were sampled through the total sampling method. Data were collected with questionnaires on supervision and performance, then analyzed using univariate, bivariate with Chi-Square, and multivariate tests through multiple linear regression. The results showed that the functions of planning, supervision, evaluation, and recording and reporting had a significant effect on nurse performance (p<0.05). On the other hand, the organizing and directing functions did not have a significant effect, while guidance showed a negative direction. The most dominant variables were recording and reporting. Thus, it can be concluded that the supervision of the head of the room has a strategic role in improving nurse performance, so it is necessary to implement consistent, structured, and continuous supervision.

This study aims to describe the transformational leadership strategy implemented in Masohi hospital and analyze its impact on the performance of human resources (HR). The research approach used is qualitative with case study design, which allows researchers to understand the phenomenon in depth in a real context. The Data was collected through in-depth interviews with eight informants, consisting of directors, field heads, room heads, and implementing staff, so that diverse perspectives were obtained from various levels of management and implementers. The data analysis process is carried out through three main stages, namely data reduction, data presentation, and conclusion/verification. The results showed that transformational leadership strategies in Masohi hospital include exemplary, inspirational motivation, innovative thinking encouragement, and attention to individual employee needs. Implementation of this strategy can improve discipline, work ethic, teamwork, and a sense of responsibility of employees in providing services to patients. In addition, it was found that the work culture built through transformational leadership can strengthen organizational commitment and improve overall service quality. However, the implementation of this strategy is not free from challenges. The obstacles that arise include complex bureaucracy, managerial competence gaps between units, as well as resistance to change among staff. This challenge requires an adaptive approach and effective communication so that the strategy can run optimally. Overall, the findings of this study confirm that transformational leadership has a positive impact on strengthening work culture and improving service quality in regional hospitals. This research is expected to be a valuable input for the development of leadership and HR management policies, not only in Masohi hospital, but also in other regional hospitals that face similar challenges.

Pulmonary tuberculosis (pulmonary TB) is an infectious disease that attacks the respiratory system, especially the lungs, and can cause various clinical symptoms, one of which is decreased oxygen saturation (SpO₂). Decreased oxygen saturation can worsen the patient's condition and affect their quality of life. Therefore, effective interventions are needed to increase oxygen levels in the body, especially through safe and easy-to-implement non-pharmacological approaches. One intervention commonly used in nursing practice is the semi-Fowler position, which is a lying position with the head of the bed elevated around 30–45 degrees, which is believed to improve lung expansion and increase ventilation. This study aims to evaluate the effectiveness of implementing the semi-Fowler position on increasing oxygen saturation in pulmonary TB patients. The study was conducted using a descriptive method through a case study approach on three pulmonary TB patients treated in the Mawar Room of Subang District Hospital. Data were collected through direct observation of oxygen saturation using a pulse oximeter at minute 0 (before intervention), minute 10, minute 30, and more than minute 60 after the patient was placed in the semi-Fowler position. The results showed a significant increase in the SpO₂ values of the three patients after 30 minutes in the semi-Fowler position, with an average increase from 92–93% to 95–96%, and these values tended to be stable for more than 60 minutes after the intervention. These findings suggest that the semi-Fowler position can be an effective non-pharmacological nursing intervention option to increase oxygen saturation in pulmonary TB patients. The application of this position is recommended in daily nursing practice to help overcome respiratory disorders, increase comfort, and accelerate the recovery process of pulmonary TB patients.

High stress can have different effects on each person. Changes that arise due to work stress can change behavior and affect mental and physical health. In addition, stress in nurses also affects the quality of hospital services. The purpose of the study was to determine the relationship between work period and workload with work stress of implementing nurses at ASA Depok Hospital in 2024. This study is a quantitative type that is analytical in nature. The research design used is a cross-sectional study. The population in this study were all nurses at RSUD ASA Depok totaling 123 people. The determination of the sample in this study used a purposive sampling technique. The sample in this study was 94 respondents. In this study, the research instrument or tool used to collect data was by using a questionnaire. The researcher used the Chi Square test with a confidence level of 95% or a significance level of 5%. Based on the results of the study, there were more who had a work period of > 5 years, namely 53 respondents or 56.4%, more nurses felt a heavy workload, namely 59 respondents or 62.8% and more nurses felt moderate work stress, namely 36 respondents or 38.3%. The results of the statistical test of the relationship between length of service and work stress with a P value = 0.001 and the relationship between workload and work stress with a P value = 0.000. It is concluded that there is a relationship between work period and workload with work stress of implementing nurses at ASA Depok Hospital in 2024. Suggestions for Nursing Management including the head of the room to add personnel in each room so that it is not too heavy to work and for nurses to be able to apply good coping management in order to prevent work stress.

Supervision is part of the directing function carried out by supervisors to improve nurse performance. Falls result in injuries such as broken bones or bleeding and can cause death. This is because nurses' lack of optimal compliance with the implementation of fall risk prevention SOP can increase the incidence of patients falling while being treated. One of the incidents of falls comes from not yet optimal SOP planning in an institution. The purpose of this research is to analyze the relationship between head of room supervision and the implementation of fall risk prevention SOP at the Sultan Agung Islamic Hospital.This research is a quantitative research with a cross-sectional approach. Data collection was carried out using questionnaires and observation sheets. The research sample consisted of 50 respondents. This research uses a total sampling technique and is processed statistically with the correlation test used in this research is the spearman rank test.The results of the spearman rank test on the room head supervision data with the implementation of fall risk prevention SOP obtained a p value of 0.000 (<0.05). For further research, it is recommended to expand the scope of research by involving more respondents and hospital institutions in order to obtain more generalizable results.

Fish growth refers to the growth of body size which includes length and weight, as well as the development of fish body tissues within a certain period of time.Growth does not only occur in a physical sense but also includes biological and physiological changes in the fish body.In an ecological context, fish growth is related to the ability to survive, adapt, and reproduce in an environment with various internal and external factors.The implementation of the practicum of population dynamics and fish stock assessment was carried out in the Nias University building, room 2 of the Faculty of Science and Technology. The morphometric measurements were carried out by measuring the total length, stag length and standard length.The total length was measured from the distance between the tip of the head end and the tip of the caudal fin back.Growth of strange mackerel through the relationship between length and weight using the growth formula expressed in the form of a linear regression equation. The equation obtained from the analysis of measurement data shows the length-weight relationship with the equation Y 2.8771x-1.7473 and R2 value of 0.6688. The coefficient b value of 1.7473 indicates that mackerel has a negative allometric growth pattern, which means weight gain. Mackerel (Rastrelliger sp.) is the main indicator of fish growth and health based on the results of morphometric studies that show variations in length and weight.
