The development of information technology has brought significant changes to the medical device procurement process, particularly within government institutions such as the Health Office. The procurement of appropriate, efficient, and objective medical devices is crucial to supporting optimal medical services, yet the decision-making process is often constrained by limited budgets and the complexity of multiple assessment criteria. This study aims to design and implement a decision support system (DSS) based on the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method to provide recommendations for medical device procurement at the Binjai Health Office. The DSS evaluates six main criteria: price, quality, durability, ease of maintenance, medical necessity, and safety level, using procurement data from the 2022–2024 period. The TOPSIS method is applied to calculate the relative closeness of each alternative to the ideal solution, enabling decision-makers to rank medical device options objectively and systematically. The findings show that the DSS successfully prioritizes procurement alternatives, helping stakeholders allocate budgets more effectively and transparently. In addition, the system minimizes subjective bias by integrating quantitative analysis with clearly defined criteria. The system is implemented in a web-based environment with MySQL as the database, ensuring accessibility and scalability for future use. Overall, this research demonstrates that integrating TOPSIS into a decision support system can enhance the efficiency, accuracy, and accountability of medical device procurement in public health agencies. The study is expected to contribute to improving budget management and strengthening the quality of health services through better resource allocation.

First aid in emergencies is an essential skill that must be possessed by nursing students as prospective health workers. Educational media in the form of practical guidebooks is believed to be able to improve students' knowledge and skills, but their effectiveness needs to be proven empirically. This study aims to determine the effectiveness of the educational media of the Emergency First Aid Guide in improving the knowledge and skills of Basic Life Assistance (BHD) for nursing students. The research design used was pre-experimental with a one group pretest-posttest design approach. The research sample consisted of nursing students selected through purposive sampling techniques. The research instruments include a knowledge questionnaire and a BHD skill observation sheet. Data analysis was carried out by the normality test and the Wilcoxon Signed Rank Test. The results showed a significant improvement in respondents' knowledge from an average of M: 12; SD ± 2.52 to M: 17; SD ± 1.55 (Z = -7.789; p = 0.00), as well as an improvement in BHD skills from M: 83; SD ± 9 to M: 99; SD ± 10.2 (Z = -7.789; p = 0.00). These findings show that educational media in the form of handbooks is effective in improving the ability of nursing students to deal with emergency situations. This media can be used as an alternative strategy in emergency nursing learning to support students' clinical readiness.

Animated films are not only a medium of entertainment but also an effective tool for delivering moral, social, and educational values through innovative storytelling and engaging visual styles. In Indonesia, although many animated films are broadcast on national television, only a limited number originate from domestic creators. This condition highlights the need to strengthen local creative content that reflects Indonesia’s cultural and environmental identity. The present design project aims to develop an alternative television program in the form of a 2D animated film that emphasizes the preservation of Mentilin, an endemic animal of Bangka Island, while simultaneously serving as an educational medium for the local community. The research and design process employed a qualitative approach, focusing on data collection through observation, interviews, and literature review to identify effective strategies for socialization and education. The animation production of Mentilin, The Tiny Tarsier was carried out in three main stages: pre-production, including concept development and storyboarding; production, involving character design, background creation, and animation; and post-production, which covered editing, sound design, and final rendering. The preliminary evaluation indicated that the animation successfully captured local cultural elements and delivered messages about environmental awareness in an engaging manner. This design is expected not only to provide a creative educational platform for the community but also to contribute to the broader efforts of environmental preservation and the development of Indonesia’s animation industry. Furthermore, the program has the potential to be expanded as a replicable model for other regions in promoting endemic species conservation through creative media.

This study aims to design and implement a damage analysis system for concrete surfaces by utilizing digital image processing based on the Canny edge detection method. The developed system allows users to upload images of concrete surfaces, which are then processed through several stages: conversion to grayscale, transformation to binary images, and crack edge detection using the Canny operator. This process aims to automatically detect crack patterns on the concrete surface. The detection results, represented as edge lines, are used to calculate the percentage of the damaged area. Based on this percentage value, the system automatically classifies the damage level into light, moderate, or severe categories. System testing shows that the Canny method can accurately identify crack patterns, with sufficient detection levels to be used in monitoring the condition of concrete surfaces. The analysis results are then presented in both visual and numerical forms, providing valuable information for assessing the structural condition of concrete. Thus, this system can serve as an efficient and effective tool for early detection of structural damage in concrete infrastructure, ultimately supporting better maintenance and repair efforts.

Fermentation of seluang fish (Rasbora spp.) pekasam is a traditional method for extending shelf life and enhancing flavor, typically produced through spontaneous fermentation dominated by lactic acid bacteria (LAB). However, uncontrolled production processes lead to significant variability in product quality. This research aims to optimize the fermentation process of seluang fish pekasam through a series of controlled microbiology-based experimental practicums. The experiments were designed to investigate the impact of two main parameters: (1) the use of a LAB starter culture isolated from high-quality pekasam, and (2) the control of incubation temperature (e.g., at 25°C and 30°C). During the fermentation period, samples were periodically analyzed to measure changes in physicochemical parameters, including pH, moisture content, and salt concentration. Microbiological analysis was performed to count the populations of LAB and other spoilage microbes. The results showed that the use of a LAB starter culture significantly accelerated the pH drop within the first 24 hours, reaching a critical pH below 4.5, which effectively inhibited the growth of pathogenic microbes. Furthermore, the optimal raw material ratio and controlled incubation temperature resulted in pekasam with a firmer texture and a more balanced sour-savory taste, differing significantly from spontaneously fermented products. Organoleptic tests confirmed panelists' preference for the product made with the optimal treatment. The conclusion of this study is that optimization through microbiology-based experimental practicums is key to the standardization and improvement of the quality and food safety of pekasam products.

The employee recruitment system is a crucial aspect in maintaining the quality of human resources in healthcare institutions, particularly hospitals based on Islamic values. Muhammadiyah Ponorogo General Hospital, as a hospital based on Muhammadiyah principles, faces the challenge of ensuring that every employee is not only technically competent but also aligned with Islamic values ​​and culture. This study aims to describe the employee recruitment process, identify the challenges faced, and explore best practices implemented at Muhammadiyah Ponorogo General Hospital. The study used a qualitative approach with data collection through in-depth interviews with Human Resources Development (HRD) and relevant stakeholders, direct observation of the selection process, and internal document review. Data were analyzed thematically to discover patterns and deeper meanings within the recruitment process. The results show that recruitment is carried out through the stages of identifying workforce needs, administrative selection, written tests, in-depth interviews to assess technical competency and Islamic value alignment, and medical examinations. The main challenge is the limited number of candidates who meet the dual criteria of having both professional expertise and moral integrity in line with Muhammadiyah values. Furthermore, maintaining transparency and objectivity in the selection process is also a crucial concern. The findings of this study indicate that the success of the recruitment system at Muhammadiyah Ponorogo General Hospital (RSU Muhammadiyah Ponorogo) depends heavily on good coordination between HRD and management, as well as the need to strengthen the value-based selection process. This way, the hospital can produce a workforce that is not only professional but also capable of supporting the institution's vision and mission of providing superior and Islamic healthcare services.

Electronic Medical Records (EMR) are medical records compiled and stored through an electronic system used to support the provision of healthcare services. The implementation of EMR facilitates faster, more practical, and integrated patient data recording. Electronic Medical Records (EMR) are designed to improve the efficiency, accessibility, and accuracy of patient information within healthcare institutions. This study used a qualitative descriptive approach with a case study design through interviews to assess the readiness of EMR implementation in terms of the 5M management aspects (Man, Money, Material, Machine, Method) at Muhammadiyah General Hospital, Ponorogo Regency. The study sample consisted of 27 healthcare workers selected using a purposive sampling technique. The case study design allowed researchers to capture in-depth insights from healthcare workers directly involved in EMR implementation. The results showed that from the Man element, most healthcare workers were ready to use EMR, as indicated by their comfort and skills in operating the application. In the Money element, there is a system maintenance budget and support for EMR development in the inpatient unit and the Emergency Room. The Material element indicates the availability of adequate software, while the Machine element includes computer devices, internet connections, and a stable server to support users. These technological resources ensure a user-friendly and reliable system. The final element, Method, is demonstrated by the existence of clear SOPs and workflows, enabling healthcare workers to understand and effectively follow the EMR implementation process. Overall, the findings indicate that the hospital is institutionally prepared for EMR adoption.    

Turnover intention is widely recognized as one of the earliest indicators of potential employee resignation, which in turn can generate considerable organizational challenges such as increased operational costs, the erosion of organizational knowledge, and declining productivity levels. While a significant body of international research has explored the antecedents of turnover intention, studies that specifically provide a narrative synthesis within the Indonesian workforce context remain scarce. Recognizing this gap, the present study seeks to identify the dominant factors that influence turnover intention in Indonesia by conducting a narrative literature review. The review focused on nine selected articles published between 2018 and 2023 in nationally indexed journals. To ensure rigor, the selection was based on predefined criteria: the articles had to employ empirical designs involving full-time employees, apply quantitative research methodologies, and explicitly examine the relationships between independent variables and turnover intention. The data extracted from the studies were analyzed thematically to identify recurring patterns and dominant themes. The analysis revealed four key factors that consistently shaped turnover intention across the reviewed literature. First, job stress was found to be a critical determinant, where prolonged work pressure and role overload significantly increased employees’ desire to leave. Second, job satisfaction emerged as a central variable, with dissatisfaction related to compensation, recognition, and career development strongly linked to turnover intention. Third, leadership style played an important role, as authoritarian or unsupportive leadership approaches heightened employees’ intention to resign. Finally, the leader’s role in fostering workplace relationships and support systems was identified as a factor influencing employee attachment and loyalty. In conclusion, this study contributes theoretically by mapping the dominant factors of turnover intention within the Indonesian context and highlights their interconnections.

This study aims to determine the level of problematic smartphone use (PSU) and revenge sleep procrastination (RBP) among MTs/SMP students in District X, while also examining the relationship between the two variables. The problem of excessive smartphone use among adolescents is increasingly important to study because it can impact sleep quality, learning concentration, and mental health. This research approach uses a quantitative correlational method with data collection through a bold questionnaire (Google Form). The research sample consisted of 103 MTs/SMP students in District X who were selected using an incidental sampling technique. The RBP variable measurement scale was developed by the researcher with reference to aspects proposed by Kroese et al. (2014). Meanwhile, the PSU Scale was developed based on dimensions formulated by Foerster et al. (2015), including withdrawal, desire, loss of control, dependence on peers, and negative life consequences. The results of the correlation analysis showed that PSU had a very strong positive relationship with RBP (r = 0.833) and was statistically significant (p < 0.000). This means that the higher a person's tendency to experience problematic smartphone use, the greater the likelihood of revenge bedtime delay. Among the dimensions of PSU, withdrawal showed the highest correlation with RBP (r = 0.831). This was followed by negative life consequences (r = 0.778), craving (r = 0.577), loss of control (r = 0.489), and dependence on peers (r = 0.333). Overall, this study concludes that PSU plays a significant role in increasing RBP trends among students. These findings highlight the urgent need for awareness and intervention programs to reduce excessive smartphone use among adolescents. Therefore, the results of this study are expected to serve as a reference for schools and parents in designing strategies to prevent the negative impacts of smartphone use on adolescents.

The development of digital technology has had a significant impact on the health sector, including eye examination services. This study discusses the development and implementation of a Digital Optoscope-based Eye Diagnostic application designed using a web platform (HTML). This application provides two main features: visual acuity testing and astigmatism testing, which can be accessed independently by users through digital devices such as laptops, tablets, or mobile phones. Users only need to follow the visual instructions presented interactively on the screen, then perform the test according to the procedure. The testing method is carried out by displaying font size settings according to the Snellen chart standard and radial astigmatism patterns. The results of each test session are automatically recorded and can be saved for further analysis. In addition, users can perform repeated tests to improve the accuracy of self-diagnosis, and the system will provide lens type recommendations based on the measurement results obtained. The trial results show that this application is able to provide convenience, efficiency, and initial accuracy in the process of examining vision disorders. This is very useful, especially for people in remote areas or with limited access to professional eye health services. Thus, the Digital Optoscope-based Eye Diagnostic application has the potential to be an innovative solution for the early digital detection of vision disorders. This study recommends further development, particularly in clinical validation, testing on a wider sample size, and integration with electronic medical record systems to enhance its benefits in comprehensive public health services. Furthermore, collaboration with medical professionals is crucial to ensure diagnostic accuracy. With this approach, the app is expected to become a reliable tool for continuous eye health monitoring.

Scabies is one of the infectious skin diseases that is still often found in Indonesia, especially in environments with high population densities such as Islamic boarding schools and orphanages. This disease is caused by an infestation of the Sarcoptes scabiei mite which causes severe itching, especially at night, so that it can interfere with the quality of sleep and daily activities of the sufferer. This condition not only has an impact on physical health, but also affects the psychological and social aspects of students. Scabies prevention efforts require adequate knowledge from each individual in order to maintain good personal hygiene and the environment. This study aims to determine the influence of health education through the peer education method on increasing students' knowledge in preventing scabies. The research method uses a quasi experiment design with a one group pre-test post-test approach. The research sample was taken using the total sampling technique, covering all students who were respondents. Data analysis was carried out by paired samples t-test to see differences in knowledge before and after the intervention. The results showed a p-value of 0.000 (<0.05) which means that there is a significant influence of the peer education method on improving student knowledge. In other words, the delivery of health information through peers is considered effective because communication takes place more intimately, is easy to accept, and is able to increase awareness of the importance of maintaining personal and environmental hygiene.
