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.

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.

Denny's house is one of the houses that uses a minimalist architectural concept. The minimalist concept has become a trend in the world of architecture, because of its simple yet effective concept, minimalist design has become one of the most preferred styles by graphic design professionals, architects, and artists (Aliwafa, 2023). The actualization of the Vitruvius architectural concept is based on Vitruvius's theory of Utility (Function Aspect), Firmitas (Strongness and Structure Aspect), and Venustas (Beauty). By comparing Vitruvius's theory with Henry Wotton's Theory, the aim is to actualize the architectural concept in the contemporary design of Denny's house as well as become a case study that can be accepted by the reader's audience. This case study uses descriptive qualitative techniques of data processing that aim to achieve study results on a comprehensive phenomenon. The application of the Vitruvius architectural concept is the focus of discussion in the contemporary design of the facade of Denny's house which becomes a reference for the discussion to examine with an architectural approach. The house becomes the initial locus of discussion by prioritizing the function of beauty, the function of strength or structure, and the function of venustas or beauty. Vitruvius is a theory used to examine the application of design theory by providing a precedent study of Denny's architectural work, which uses a minimalist functionalist theme. This study examines Vitruvius' theory regarding the relevance of design to Denny's home.

The objective of this study is to evaluate the impact of load balancing implementation on website service performance to enhance system efficiency and reliability. The research object is a website accessed through seven service endpoints: Login, Homepage, Blog, About, Shop, Contact, and Post Checkout, with a total of 3,500 requests. The testing was conducted under two scenarios: a single server architecture and an architecture utilizing a load balancer (HAProxy) implementing the Round Robin algorithm. The testing method employed Apache JMeter to simulate load and measure various performance parameters, including average response time, throughput, standard deviation, bandwidth usage, average response size, and error rate. The results indicate that the use of a load balancer significantly reduced the average response time from 7,551 ms to 3,278 ms, increased throughput from 12.5 to 27.3 requests per second, and improved response time stability by reducing standard deviation across all endpoints. Bandwidth usage also increased without changes in average response size, with the error rate remaining at 0% in both scenarios. The study concludes that implementing load balancing with HAProxy effectively enhances website service performance in terms of efficiency, capacity, and system stability, and is recommended as a performance improvement solution in resource-constrained environments.

The The aim of this study is to examine the migration pattern of the Minahasa people to the Netherlands over three generations, focusing on the economic aspect that became one of the main drivers of migration. This research uses a qualitative approach with descriptive analysis that combines historical data, interviews and literature studies related to the migration phenomenon that occurred from the early 20th century to the present. The three generations of Minahasa migration to the Netherlands include: (1) the first generation that left during the colonial period, generally driven by employment factors and the role of the Netherlands as a colonial state, (2) the second generation that began to migrate in post-independence Indonesia, where economic and educational factors were the main considerations, and (3) the third generation that migrated with more diverse motivations, including the search for better economic opportunities and family reasons. The research found that economic migration was a very important factor in each generational phase, although personal motivations and socio-political developments in Indonesia and the Netherlands also played an important role. The impact of this migration is not only visible at the individual level, but also affects social and economic changes in both countries, both in terms of the integration of the Minahasa community in the Netherlands and their contribution to the economic development of the Netherlands. In addition, this study also highlights the differences in migration characteristics from generation to generation.The reasons for the Minahasa migrated to the Netherlands from the first generation to the present are as follows: (1) KNIL were soldiers of the Dutch East Indies Kingdom, some former KNIL soldiers from Minahasa chose to fly and migrate to the Netherlands. The interaction of culture, religion and language that lasted for a long time eventually gave birth to emotional closeness between immigrants, in this case the Dutch and the Minahasa. (2) The Netherlands and the Minahasa are closely related because Minahasa is the 12th province of the Netherlands. This made people loyal to Twapro choose to migrate to the Netherlands. (3) On Santa Claus (a celebration of Christmas welcoming day, which is celebrated by the Dutch and Minahasa residents), on December 5, 1957, the Indonesian government carried out a massive nationalization of assets belonging to the Netherlands, the embassy and consulate (Netherlands) was closed, and evacuation plans were prepared everywhere (massive expulsion of Dutch citizens out of Indonesia). At that time, not only Dutch citizens were forcibly evicted, but also many Minahasa people who migrated to the Netherlands on their own wishes and choices by boarding Dutch ships together to the Netherlands. (4) A movement involving Minahasa people occurred in 1958 which was Permesta. For a just and prosperous economy as well for a life that is safe, comfortable and peaceful. (5) The creation of the Jakarta Charter, which was signed on June 22, 1945. At this time, gradually, the Minahasa people migrated to the Netherlands because they were worried about their religion as a minority in their country. (6) Many Minahasa people have been displaced, as a result of the "prejudice" of some Indonesians towards them. In the post-Independence period of the Republic of Indonesia, there were prejudices against Christians. This prejudice was based on the a priori attitude of other groups who accused them of being Dutch 'sympathizers'. Because their religion is Christianity who came from the Netherlands and were educated by evangelists from the Netherlands. (7) Assimilate in the context of marriage. (8) The similarity of customs, customs, traditions, culture and beliefs between the Dutch and the Minahasa. There is a bright future in the exchange of personal stories between Minahasa people, migrated Minahasa and native Dutch who will understand each other much better. It is also hoped that the sciences in the fields of architecture, water management or agriculture, plantations and others will enable the Minahasa diaspora in the Netherlands to use them to develop and advance their Minahasa homeland, through hard skills and soft skills. There are many potentials and opportunities to tie and strengthen relations between the two countries.

Older people sometimes become a new problem for a family or government. These problems are the unavailability of access to health care, the lack of old age insurance, and the social support from the family to care for them. The aging process certainly has an impact on all aspects of life, especially health because with increasing age, the function of the body's organs will decrease both due to scientific factors or disease. The decreased function of the body's organs makes the elderly limited in carrying out activities because of the limited energy they have. Through the design of the Nursing Home with the Biophilic Architecture approach, it can help the elderly from feeling lonely and so that their illness does not get worse and it is hoped that they can recover and continue to carry out more productive activities. So this design can be a social space for the elderly who are able to respond to the conditions and activities of the elderly.

Elderly is an integral part of the human life cycle. Basically, every individual will experience the stage of old age after going through childhood, adolescence and adulthood. In the elderly phase, the human body slowly experiences a decline in function, which is an early sign of the aging process. The plan for this nursing home aims to be a place for the elderly to gather with their community, preventing them from feeling lonely or neglected. The implementation of the Healing Environment concept also influences the elderly's experience of enjoying old age, involving architecture that integrates healing systems from nature, the five senses and psychological aspects.

Medan is home to a number of historical buildings from the colonial era and the Islamic Malay Kingdom of Deli, many of which are now heritage sites. However, some buildings remain abandoned, such as the Warenhuis building on Jalan Hindu. Built in 1918 and protected by Law No. 11/2010 and Medan Mayor Decree No. 433/28.K/X/2021, Warenhuis needs to be revitalized to maintain its cultural significance. The COVID-19 pandemic has increased interest in digital connectivity and art. Advances in virtual reality and augmented reality have created new immersive art experiences. The 2000s saw significant growth in the field of new media art, with more and more art collectives utilizing technology. The Cultural Promotion Law No. 5/2017 focuses on the protection, development, and utilization of the arts. Medan, the third largest city in Indonesia, has great potential as a digital art gallery that helps promote culture through conservation, development and community participation. The regeneration of Warenhuis as a digital art gallery uses an infill development design that blends contemporary digital art with the classic architecture of the building, creating a dynamic and inclusive art space while maintaining its historical value.  

Growing demand for electricity savings has led to the development of an automatic LED emergency light system. It is based on providing light when the power is cut off. Once fully charged, the battery ceases charging, and in the event of a power failure, the LEDs are automatically powered by the battery. The project focuses on two primary functions: it automatically activates during power outages to give illumination, eliminating the need to search for the switch, and the battery rapidly begins recharging as the main power is restored. The emergency light is crucial due to the inconsistent voltage distribution and frequent power outages in operational regions of communities and diverse enterprises. The system includes a power supply that converts 230V AC to 12V DC, a relay that uses a control pulse to alternate between connecting the battery to the LEDs and isolating it, and a rechargeable Li-ion battery that supplies power to the LEDs during blackouts. The parallel-connected LEDs light up during a power outage in the circuits. The circuit architecture shown here serves to mitigate the entire discharge of the battery, hence enhancing the battery's longevity. Key components of the system include a step-down transformer, a bridge circuit to convert AC to DC, a Zener diode to maintain voltage stability, capacitors for energy storage, and various diodes to control current flow. The project highlights the advantages of LED emergency lights, such as efficiency, longevity, and minimal energy waste, though it acknowledges the higher initial cost and temperature sensitivity as disadvantages. The automatic LED emergency light is suitable for use in homes, offices, retail shops, and other commercial settings. The project demonstrates a cost-effective and compact solution that enhances daily life by providing reliable lighting during power failures.

Face is one of the unique parts of the human body and can be used for identification purposes. Research on the application of facial recognition biometric technology has been carried out since 1960 and continues to be refined to this day. Humans can easily recognize an object or image, but not for a computer. This is the background behind the creation of a scientific discipline called Computer Vision. One deep learning algorithm that has been extensively researched and used for classifying various images is Convolutional Neural Network (CNN). The COVID-19 requires us to comply with health protocols, one of which is by wearing a mask when doing activities outside the home. The biometric presence system that is commonly used today can pose a risk of transmission because they have to touch the surface of an object that may have been contaminated from someone infected with the COVID-19 virus. Seeing the risks posed and the relevance to the times when people are accustomed to wearing masks, a study was conducted to create a masked face recognition system using the Convolutional Neural Network (CNN) method with VGG16 architecture. The dataset used was in the form of people's faces who were willing to be the object of research. This study produced highest accuracy rate of 85,71% with the application of various types of masks, namely surgical, cloth, and KF94 masks.
