The elderly population in Indonesia, particularly in Surabaya, has been growing significantly, making the need for facilities serving the elderly increasingly urgent. Elderly rehabilitation services must be provided holistically, covering four main aspects: social, health, psychological, and spiritual. However, the implementation of holistic services in some nursing homes still shows differences in quality and has not fully met the expected standards. This study aims to analyze and compare holistic services in two nursing homes, namely Griya Lansia Husnul Khatimah in Malang and UPTD Griya Wreda Jambangan in Surabaya. The method used in this study is descriptive-qualitative comparison, with a field observation approach and a literature review to establish assessment criteria based on the four aspects of holistic services. The research results show that both nursing homes analyzed have shortcomings in the social and psychological service aspects. This indicates a gap in the quality of services received by the elderly in both homes, which needs attention to ensure that holistic services can be applied more effectively and in line with the established standards. This study is expected to provide recommendations for improving the quality of services in nursing homes in Indonesia.

The increase in the number of elderly residents demands the provision of residential facilities that not only meet physical needs, but also support the psychological and social well-being of their users. This study aims to formulate the concept of behavioral architecture-based nursing home design by focusing on the relationship between elderly activity patterns, privacy levels, and spatial relationships of space in the local context of Indonesia. This study uses a qualitative-descriptive approach in the framework of architectural design, with data collection through observation of elderly activities, site analysis, and documentation studies. Activity data was analyzed to identify space needs and usage patterns, then synthesized with site characteristics to formulate the concepts of zoning, circulation, and behavior-based spatial relationships. The results of the study show that the activities of the elderly form a layered behavioral structure, including residential and health activities as primary needs as well as social, productive, and educational activities as support for psychosocial welfare. Hierarchically arranged space zoning based on privacy levels has been proven to improve the readability of the space, sense of security, and comfort of the elderly. The integration of green open spaces as part of the activity system also strengthens support for light physical activity and social interaction. This study confirms that the application of behavioral architecture allows the translation of data on elderly behavior and site conditions into a contextual, humanist, and quality-of-life-oriented design concept. These findings provide practical implications for designers and policymakers in the development of sustainable elderly housing.

Personal hygiene is an essential factor in maintaining the health and quality of life of the elderly, as aging is often accompanied by a decline in physical strength, mobility, and cognitive function that can reduce the ability to maintain personal cleanliness independently. Limited understanding of the importance of personal hygiene may increase the risk of infections, skin disorders, and other health complications, making education and awareness crucial for promoting better hygiene behavior. This study used a descriptive correlational design with a cross-sectional approach involving 204 elderly individuals residing at the Pucang Gading Elderly Social Service Home in Semarang and Wening Wardoyo Ungaran, with 135 respondents selected using a non-probability sampling technique. Data were collected using validated and reliable questionnaires measuring the level of understanding and personal hygiene practices and were analyzed using the Somers’d statistical test. The results showed that most respondents were female (60%) and aged between 70–79 years (48.9%). The level of understanding of personal hygiene among the elderly was predominantly in the moderate category (72.6%), and their personal hygiene practices were also mostly categorized as moderate (72.6%). Statistical analysis revealed a p-value of 0.000 (<0.05) with a correlation coefficient (r) of 0.472, indicating a positive and significant relationship between the level of understanding and personal hygiene practices. These findings suggest that improving knowledge through continuous education and guidance from health workers is necessary to enhance awareness, independence, and hygiene behavior among the elderly.

The elderly are highly susceptible to ascariasis infection because, in addition to the occurrence of immunosenescence, helminths possess the ability to evade host immune responses, making them difficult to eradicate. This community service activity aimed to improve health literacy and early detection of diseases among the elderly in Pejaten, South Jakarta, with a specific focus on Ascariasis. The program was successfully attended by approximately 70 residents, where a medical team from the Faculty of Medicine and Health conducted comprehensive health history assessments and free medical check-ups. This education proved vital as a catalyst for behavioral change, shifting the community's initial perception that worm infections only affect children to an understanding that adults and the elderly are also at high risk. Through health screenings, residents also gained critical insights into their physical condition, including blood pressure, heart, lung, digestive, and skin health, as well as identifying personal risk factors for Ascariasis.

Sleep quality is a crucial component of health and overall well-being among older adults, as the aging process is commonly associated with various physiological, psychological, and environmental changes that may significantly disrupt normal sleep patterns. Declining bodily functions, increased health problems, and changes in daily routines often contribute to sleep disturbances in later life. This literature review aims to analyze the factors influencing sleep quality in the elderly by synthesizing findings from relevant national and international studies published in recent years. Various factors were identified, including physiological conditions such as chronic diseases, pain, and hormonal changes; psychological factors such as anxiety, depression, stress, and cognitive decline; lifestyle-related factors such as levels of physical activity, dietary habits, medication use, and caffeine consumption; and environmental aspects including noise exposure, lighting conditions, temperature, and overall bedroom comfort. The reviewed literature consistently indicates that poor sleep quality is strongly associated with impaired physical health, reduced cognitive function, increased fatigue, and decreased emotional well-being in older adults. This review highlights the importance of comprehensive, multidisciplinary interventions that address both intrinsic and extrinsic determinants of sleep to effectively improve overall sleep quality among elderly populations.

This study aims to develop a predictive model using linear regression to identify potential arrhythmias in the elderly based on electrocardiogram (ECG) data. Data were collected through observations at healthcare facilities from elderly patients with indications of arrhythmia, then preprocessed such as cleaning, normalization, feature selection, and outlier checking were carried out. The features used include PR interval, QRS duration, QT interval, and heart rate. The dataset was divided into training data (80%) and test data (20%) to build and evaluate the model. The training results showed that the model was able to predict the risk of arrhythmia with a Mean Squared Error (MSE) value of 0.15 and a coefficient of determination (R²) close to 1. Evaluation using a confusion matrix showed an accuracy of 76.19%, precision of 82.80%, recall of 76.19%, and F1 score of 72.70%. These results prove that linear regression can be used as an initial approach in the early detection of arrhythmias non-invasively in the elderly. This study provides a foundation for the development of ECG data-based clinical decision support systems and suggests future exploration of more complex models and integration with real-time monitoring technologies.
