Acute Respiratory Infection (ARI) is one of the main causes of morbidity and mortality among children under five years old worldwide, especially in developing countries including Indonesia. Poor housing conditions such as inadequate ventilation, high occupancy density, humidity, and insufficient lighting may increase the risk of ARI in children. This study used a descriptive observational method. The population consisted of all toddlers suffering from ARI in the working area of Kupang Kota Health Center in 2025 totaling 911 cases. The sample consisted of 91 houses of toddlers with ARI determined using the Slovin formula. The results showed that several houses of toddlers with ARI did not meet healthy housing requirements, particularly in terms of occupancy density, ventilation, humidity, and lighting. The condition of healthy housing for toddlers suffering from ARI in the Kupang Kota Health Center working area has not fully met environmental health standards.

The issue of uninhabitable houses still requires an accurate identification mechanism because the manual data collection process has the potential to be time-consuming, costly, and subject to subjectivity in determining aid priorities. This study aims to develop a classification model to identify habitable and uninhabitable houses based on family socioeconomic data using the Random Forest algorithm. The research method includes data preprocessing, data division using stratified split in three scenarios, baseline model development, and optimization through hyperparameter tuning using GridSearchCV with 3-fold cross-validation and balanced class_weight parameters. The data used includes variables such as education type, employment status, occupation type, number of family members, and family insurance type. The test results show that the 70:30 data division scenario after tuning provides the best performance with a recall value of 0.5797 for uninhabitable houses and an F1-score of 0.4746. Feature importance analysis shows that education type and employment status are the most influential variables in the classification. The results of this study show that the model built is capable of increasing sensitivity in detecting uninhabitable houses to support more objective field survey prioritization.

The Uninhabitable House Rehabilitation Program (RTLH) is a government policy aimed at improving the quality of housing for low-income communities while simultaneously supporting the acceleration of the eradication of extreme poverty. Although it has been implemented in various regions, the implementation of the RTLH program has shown varying achievements, thus requiring a comprehensive evaluation. This study aims to analyze the evaluation of the RTLH Program in Indonesia based on William N. Dunn's six policy evaluation indicators: effectiveness, efficiency, adequacy, equity, responsiveness, and accuracy. The research method used is a Systematic Literature Review (SLR) of scientific articles discussing the evaluation of the RTLH Program in various regions. The analysis was conducted by reviewing previous research findings based on the six policy evaluation indicators. The results of the study indicate that the RTLH Program is able to improve the quality of community housing and has received a positive response from beneficiaries. However, its implementation still faces obstacles such as budget limitations, equal distribution of beneficiaries, and data updates. Therefore, strengthening funding, data collection, and coordination between stakeholders is needed for more optimal and sustainable program implementation.

Sutera Subdistrict is an area affected by floods and landslides, causing significant damage to residential areas. Most houses suffered severe damage and are no longer habitable, making housing relocation a crucial post-disaster response. This study aims to identify settlements located in disaster-prone zones and determine potential land areas for housing relocation in Sutera. The method applied involves scoring and weighting combined with spatial analysis of various physical parameters and disaster vulnerability levels.The results indicate that Sutera Subdistrict has considerable potential land for housing relocation, with the highest potential found in Nagari Amping Parak Timur. However, the physical characteristics of the area and variations in disaster vulnerability require selective and planned land utilization. Disaster vulnerability maps serve as an essential basis for spatial planning and development control, particularly in determining relocation sites. In addition, strengthening mitigation efforts and enhancing community preparedness are necessary to minimize disaster risks and support the development of a safer and more sustainable area.

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 findings indicate that the Car Free Day event successfully increased community participation, strengthened visual recognition of the residential brand, and improved public perception of Telaga Harmony Residence as a healthy and environmentally friendly housing area. The implications of this study suggest that community-based events combined with consistent branding and visual communication strategies can effectively enhance residential identity and social cohesion, and may serve as a reference for similar community development programs in the future.

Slums are an urban issue that arises due to rapid population growth and the limited capacity of local governments to provide adequate housing and basic infrastructure. This leads to areas with low environmental quality, limited access, poor drainage, and high socio-economic vulnerability. A similar phenomenon occurs in Jambi City, which requires a sustainable handling strategy. This study aims to analyze the strategies implemented by the Department of Public Housing and Settlement Areas of Jambi City in addressing slums and assess their contribution to environmental quality. A descriptive qualitative approach was used to understand the policies, program implementation mechanisms, and institutional challenges. Data was collected through interviews with government officials, field observations, and analysis of planning documents. The results indicate that the strategy focuses on improving basic infrastructure, such as road construction, drainage rehabilitation, and the provision of settlement facilities. This program enhances environmental quality and accessibility but faces challenges such as budget limitations, suboptimal inter-agency coordination, and the socio-economic conditions of the community. Addressing slums requires a more comprehensive approach, including collaborative governance, increased community participation, and adaptive policies to ensure sustainable improvements.

The increasing demand for housing in tropical regions requires building materials that are fast to apply, environmentally friendly, and resilient to extreme climate conditions as well as disaster risks. Conventional interlocking bricks are often chosen for their ease of construction, yet they still face challenges such as moisture and early cracking. This study proposes the innovation of the Hybrid Living Green Brick, a combination of lightweight bricks made from rice husk ash and fly ash waste (FRCB) with a biological layer of cyanobacteria. FRCB improves compressive strength by approximately 30% with the addition of 5% rice husk ash, achieving 65 kg/cm², thereby meeting Class 50 requirements (≥50 kg/cm²) according to SNI-15-2094-2000. The incorporation of 3% cyanobacteria provides an additional though not significant strength improvement, while still within the Class 50 category. It also reduces brick weight by 4.3%, with further optimization potential through cyanobacteria integration, and lowers carbon emissions from the firing process. Cyanobacteria induce the formation of CaCO₃ layers that seal pores, reduce water absorption by an average of 10%, and provide self-healing properties for microcracks. Preliminary observations indicate that FRCB offers stable mechanical performance, while biological activity was observed on the 7th day with the formation of pale-white mineral layers continuing until the 28th day. This hybrid innovation shows potential to support sustainable and disaster-resilient tropical construction by combining the mechanical strength of waste-based materials with the biological durability of cyanobacteria against extreme climates. Despite challenges related to moisture control and production standardization, the Hybrid Living Green Brick concept opens new pathways for developing environmentally friendly construction materials that are more adaptive to disaster-prone tropical conditions.

Limited access to adequate housing remains a major challenge for low-income households in Indonesia, including in Banyumas Regency. The subsidized housing program has been implemented as a public policy instrument to improve housing affordability while enhancing social and economic welfare. This study aims to analyze the role of subsidized housing in improving housing access and the economic conditions of low-income communities in Banyumas Regency. The research adopts a qualitative approach using a documentation study method by collecting and analyzing policy documents, official government reports, scholarly journal articles, and relevant publications related to subsidized housing and the socio-economic conditions of low-income households. Data analysis was conducted through content analysis to interpret the role of subsidized housing based on indicators of housing affordability and household economic impacts. The findings indicate that subsidized housing significantly reduces the housing cost burden of low-income households from levels exceeding the affordability threshold to a more economically manageable range. The reduction in housing expenditure contributes positively to household economic stability by allowing savings and reallocation of income toward productive needs such as education, healthcare, and financial security. However, the effectiveness of subsidized housing in improving economic outcomes is still influenced by location and accessibility of housing areas. This study concludes that subsidized housing plays a crucial role in expanding housing access and improving the economic conditions of low-income communities, while requiring integrated and sustainable policy support to maximize its long-term benefits.

This study aims to analyze the factors influencing people's decisions to use a Home Ownership Credit (KPR) with a murabahah contract at a sharia bank in Tebing Tinggi City. The research method used is a descriptive qualitative approach, with data collection techniques through observation, in depth interviews, and documentation of people who have used the murabahah KPR product. Informants were selected purposively to obtain relevant and in depth data. The results show that people's decisions are influenced by several main factors, including compliance with sharia principles, price transparency, certainty of fixed installments, ease of financing processes, promotions conducted by the bank, housing location, and the brand image of the sharia bank. The murabahah contract is considered to provide clarity of profit margins from the start and stability of installment payments throughout the financing period, thereby increasing public security and trust. These findings indicate that consistent application of sharia principles and appropriate marketing strategies play a significant role in increasing public interest in sharia housing financing products.

Labor productivity is a critical factor in construction project success as it directly affects time, cost, and work quality. In the Palm Vista Residence housing development project, delays in ground floor structural works indicate suboptimal human resource performance. This study aims to analyze labor productivity levels, identify factors influencing productivity, and formulate strategies to improve productivity in sloof beams, columns, and floor slab works. The research employs a quantitative approach with descriptive-analytical methods through field observations, questionnaires, and interviews. Labor productivity is measured using the work sampling method and the Labour Utilization Rate (LUR), while influencing factors are analyzed using multiple linear regression. Strategy prioritization for productivity improvement is determined using the Analytical Hierarchy Process (AHP). The results show that labor productivity is at a moderate level and is significantly influenced by work experience, managerial aspects, and coordination and planning. The priority strategies include improving worker competence and strengthening project management practices. These findings are expected to provide practical guidance for construction labor management to enhance efficiency and ensure timely project completion.

The house renovation program is one of the government's efforts to improve the quality of housing for low-income people. However, the process of selecting recipients of home surgery assistance is often faced with obstacles in determining the right and fair priorities for recipients. Therefore, this study aims to design and implement a home surgery decision-making system at the Housing, Residential Areas, and Land Office using the Weight Product (WP) method. The WP method was chosen because of its ability to conduct an objective assessment of various relevant criteria, such as the condition of the house, ownership status, level of welfare, and socioeconomic needs of the recipient. This system will give weight to each criterion used to determine the priority of home surgical assistance for residents in need. In its implementation, this system is able to process data from various prospective recipients and produce an automatic and transparent order of priority recipients. The results of the evaluation show that this system can improve efficiency and accuracy in the decision-making process, as well as assist the Housing Office in implementing the house renovation program more on target. With this system, it is hoped that the home renovation program can provide greater benefits to people in need, as well as accelerate the implementation of better housing programs.

The process of determining eligibility for social assistance recipients is often constrained by subjective assessments and uncertainty in decision-making criteria. This condition can lead to inaccurate targeting and unfair distribution of aid. Therefore, an appropriate decision support method is required to handle data uncertainty effectively. This study aims to apply the Fuzzy Mamdani method to determine the eligibility of social assistance recipients based on several assessment criteria. The criteria used in this study include monthly income, number of dependents, and housing conditions. The research method consists of data collection, fuzzification, formulation of fuzzy rules, inference using the Mamdani approach, and defuzzification to obtain a crisp output value. The results show that the Fuzzy Mamdani method is able to classify recipients into eligible and non-eligible categories more flexibly compared to conventional methods. The generated eligibility values reflect real conditions more accurately by considering degrees of membership for each criterion. The implementation of this method can assist decision-makers in improving the accuracy, objectivity, and fairness of social assistance distribution. This research is expected to contribute to the development of intelligent decision support systems in the social welfare sector.

The United States is often called the "land of the free" and the "land of opportunity," but its history is also rife with discrimination and injustice. This abstract explains how racism and inequality have shaped American society throughout the ages. This discrimination began with the system of slavery imposed on African Americans in the 17th century. This system not only took away their freedom but also placed them in a highly unfair situation. After slavery ended, discrimination persisted through Jim Crow laws, which allowed for racial segregation in areas such as education, transportation, and public services. Additionally, other groups such as Native Americans, Asian immigrants, and Latino communities also faced oppression. Native Americans' ancestral lands were confiscated, and they were forced to relocate to reservations. Asian immigrants experienced unfair treatment, including bans on entry and exclusion. Although the Civil Rights Movement of the mid-20th century successfully eliminated many laws that discriminated against, injustice persists. Systematic forms of racism are still evident in economic inequality, the way the law is administered, and disparities in access to education and adequate housing. Thus, American history is a story of the ongoing effort to realize the promise of justice for all its people, a process that continues to this day.

A market is a place where buying and selling transactions take place between sellers and buyers at a specific time and place. This definition encompasses several key elements: the presence of sellers, buyers, a specific place and time, and a transaction agreement. Such markets are also known as traditional markets. "Surprise" or "overflow" markets are markets that open suddenly and briefly. "Surprise" or "overflow" markets are increasingly common in various locations. There are many reasons why people enjoy shopping at these markets. One example is the very low prices, especially compared to shopping at supermarkets or malls. Over time, with the increasing demand for basic necessities, the "surprise" market, located along the road in the Vila Mutiara Cikarang housing complex, has also experienced gradual development. The number of traders and buyers has increased, the trading space has expanded, and transaction times have decreased. This "surprise" market is located along the road in the Vila Mutiara Cikarang housing complex, starting from the second block to the end of the road exiting the housing complex. The "surprise" market operates during peak hours, especially in the morning, when this time is not only for market activities but also for many activities such as going to work, school, and other activities.
