The North Sumatra Provincial Museum, as one of Indonesia’s leading cultural tourism destinations, encounters challenges in facilitating effective communication for international visitors. Despite housing extensive collections of Batak, Malay, and Nias artifacts that attract thousands of tourists annually, the limited use of English often constrains intercultural interaction. This study aims to examine the role of English as a medium of communication in enhancing foreign visitors’ experiences, identify linguistic barriers, and propose improvement strategies. Employing a descriptive qualitative case study design, data were collected through in-depth interviews and participant observation involving 50 international tourists (aged 18–65) from Europe, the Americas, and Asia who visited between January and March 2023. Data were analyzed thematically using NVivo software, supported by museum documents such as brochures and the website. Findings revealed that English proficiency among staff and the availability of English-language materials increased visitor satisfaction by 75%. However, communication barriers included the strong local accent (reported by 40% of respondents) and the lack of English-language audiovisual guides, which limited engagement. Recommendations include intensive English training focused on tourism vocabulary and phonetics, development of multilingual digital content, and collaboration with universities for volunteer interpreters. This research contributes theoretically to applied linguistics in tourism and practically to museum management enhancement.

The purpose of this study is to analyze the social and economic characteristics of fishing households in Muara Telake Village and to identify the supporting and inhibiting factors affecting fishermen. This research employs a quantitative descriptive method with a descriptive analysis approach and purposive sampling technique, involving 24 respondents. Data were analyzed using percentage techniques to illustrate the overall social and economic conditions of the fishermen. The results indicate that the social condition of fishermen falls into the “moderate” category, with an average percentage of 67.29%, covering indicators such as education, age, number of dependents, and health. Meanwhile, the economic condition is also categorized as “moderate,” with an average percentage of 53.70%, encompassing income, expenditure, housing conditions, and asset ownership. Supporting factors include good health, government assistance, family support, and the fishermen’s experience. Conversely, inhibiting factors include low education levels, unpredictable environmental conditions, limited capital, fluctuating fuel prices, and restricted market access, which affect productivity and the welfare of fishing households. These findings highlight the need for targeted interventions to enhance both social and economic well-being.

South Sumatra is a province with high natural resource potential in the palm oil plantation sector. The increasing demand for palm oil has led to many companies operating in this sector. One such plantation company is PT. Agro Muara Rupit, located in Rawas Ulu District, North Musi Rawas Regency, South Sumatra Province. This research is important because plantations are not only assessed from a commercial perspective, but must also have a positive impact on environmental sustainability. One environmentally conscious design concept is ecological architecture. Ecological architecture plays a role in protecting ecosystems from damage and creating comfort for residents from a physical, social, and economic perspective. This research aims to create environmentally conscious residential designs by applying ecological architecture concepts, ensuring the preservation of the natural environment. The research method used is a qualitative descriptive method with stages namely problem identification, data collection, analysis, and concept development, then the concept is implemented into the design. The results of this study are the implementation of four aspects of the ecological architecture concept in residential environments, including through natural ventilation and lighting systems by creating openings in the building, energy savings by using solar panels, the use of natural materials in the building mass such as clay, wood and bamboo, and the application of a bio pore system as water absorption.

The increasing number of students in major cities such as Medan has created an urgent need for temporary housing that is adequate, comfortable, and sustainable. In response, the Indonesian government, through the Ministry of Public Works and Public Housing (PUPR), launched the "One Thousand Towers Program," which includes the development of rental apartment buildings (Rusunawa) for students. However, housing provision must go beyond quantity—it must also consider environmental aspects and the quality of life for its occupants. Therefore, a green architecture approach serves as the foundation for the design of environmentally friendly student housing. This project aims to create a vertical residential facility that not only fulfills the basic function of shelter but also supports learning activities, social interaction, energy efficiency, and environmental sustainability. The design applies key principles of green architecture such as natural lighting, cross ventilation, the use of eco-friendly materials, and the integration of green open spaces. In addition to double-room residential units, the building is equipped with supporting facilities such as study areas, a library, cafeteria, and rooftop garden. The design methodology integrates both primary and secondary data analysis, as well as a comprehensive site study covering climate, noise levels, circulation, and building orientation. The building form concept is developed modularly and efficiently through mass transformation, resulting in an inner court that provides natural light and air. Supported by energy-saving utilities, this design is expected to offer a student housing solution that is not only functional and aesthetic but also contributes to sustainable and high-quality urban development.

Housing, as a basic human necessity, demands not only physical comfort but also assurance of safety and legal protection for its residents. In recent years, the rise in security violations within residential areas has raised serious concerns, especially regarding the authority of housing management and the frequent neglect of residents’ rights. Various security policies such as 24-hour gate security, CCTV installation, and visitor access restrictions are often enforced without a clear legal basis and without the participation of residents, thereby creating the potential for legal violations, including those related to criminal law and human rights. This study aims to analyze the forms of criminal liability that may be imposed on housing management in cases of negligence or abuse of authority in the implementation of security policies. It also examines the forms of legal protection available to residents and identifies potential criminal law violations arising from such policies. The research adopts a normative and empirical juridical approach, with a case study conducted at DL Sitorus I Housing Complex in Simalungun Regency. The results of the study show that the security policies at DL Sitorus I lack a valid internal legal foundation, were not developed through participatory means, and are not supported by standardized operating procedures (SOPs). This situation creates room for overreach by security personnel, such as arbitrary detention of visitors and unauthorized interrogations, which may violate Article 333 of the Indonesian Penal Code. Management may be held indirectly criminally liable under the principles of culpa in vigilando (negligence in supervision) and culpa in eligendo (negligence in the selection of personnel). The study recommends the formulation of internal regulations based on resident participation and the provision of legal training for security officers to ensure a fair, transparent, and legally compliant residential security system that upholds the principles of criminal law and human rights protection.

Low-Income Communities (MBR) often live in Uninhabitable Houses (RTLH) due to financial constraints, which hinder their ability to improve their welfare and meet their basic living needs. The government is responsible for fulfilling the need for Decent Housing (RLH) for the community, which is realized through the Stimulant Assistance for Self-Help Housing (BSPS) program. The BSPS program aims to improve the quality of housing for the community through financial assistance and empowerment. This research was conducted in Belawan Bahari Village, Medan Belawan District, Medan City, which is a coastal area prone to tidal flooding. The main informants in this study were the Chairpersons of Assistance Recipient Groups I and II of the BSPS Program. Additional informants included the Head of Neighborhood Unit XII in Belawan Bahari Village. Key informants consisted of the Commitment Making Officer for Self-Help Housing and RUK, as well as Technical Experts from BSPS who are responsible for the activities and implementation of the BSPS program in Belawan Bahari. Data collection techniques were carried out through literature studies and field studies, including observation, interviews, and documentation. The data obtained in the field were then analyzed qualitatively by the researcher to draw conclusions from the research findings. The results indicated that the BSPS program in Belawan Bahari Village was effective in providing decent housing for aid recipients. This effectiveness was assessed based on program effectiveness indicators determined by Sutrisno, demonstrating success in terms of program understanding, targeting accuracy, timeliness of implementation, achievement of objectives, and tangible changes for aid recipients. Decent housing was evaluated based on building durability, adequacy of living space, access to safe drinking water, proper sanitation, as well as lighting and ventilation.

The analysis results of the interest rate of 10% with an investment period of 10 years. The technical feasibility of KDB is 50.2%, KLB is 0.6, KDH is 79%, and RTH is 58.4%. For economic feasibility, NPV is Rp. 5,506,655,627, BCR is 1.12113647, IRR is 17,09%, PP is 3.75 years, and PI is 1.376. This housing is feasible to use.

This study aims to examine the use of amortization schedules and the repayment fund approach in Public Housing Credit. By applying quantitative descriptive methods and a case study approach, this study simulates a mortgage with a credit ceiling of Rp163,800,000, a tenor of 15 years, and an interest rate of 5.65% for the first to fifth year and 13% for the sixth to fifteenth year. The results of the simulation show that without any additional strategies, the total interest to be paid reaches Rp138,887,134.14, which is almost equivalent to the total principal loan. However, by using a sinking fund strategy through regular savings of Rp1,000,000 every month (with an interest rate of 0.25% per month) for 5 years, the collected funds are Rp64,444,800 which significantly reduces the remaining principal loan. As a result, the total interest is reduced to Rp87,864,324.85, which means there is a savings of Rp51. 022. 809.29. Furthermore, this strategy has the potential to shorten repayment time. In conclusion, sinking funds are an effective approach to reducing interest burden and accelerating the repayment of Public Housing Loans.

This research was conducted with the aim of analyzing the effectiveness of community empowerment through the uninhabitable housing (Rutilahu) program in the city of Surabaya to improve community welfare. This research uses qualitative research, with data collection techniques through observation, interviews and documentation. The research results show that the effectiveness of community empowerment through the uninhabitable housing (Rutilahu) program in the city of Surabaya to improve community welfare has been effective in several aspects but still has shortcomings in the socialization aspect of the program. Even though the program has been successful in achieving targets, there are still shortcomings in socializing the program to the community. The large number of people who do not know about this program shows that outreach efforts need to be increased to be more optimal. By conducting regular direct outreach, going around to every sub-district and RW to hold outreach and invite the public so that people also know about this program.

One approach the government employs to decorate public welfare, mainly among low-income families, is through social help initiatives. however, the subjectivity inside the choice process regularly ends in mistargeting all through implementation. This observe objectives to apply the ok-Nearest Neighbor (ok-NN) and Naive Bayes algorithms inside a decision support device to perceive eligible recipients based on community statistics. The ok-NN algorithm determines similarity by calculating the Euclidean distance among new and current facts, whilst the Naive Bayes set of rules utilizes a probabilistic method based at the likelihood of attribute incidence inside each elegance. Key criteria considered consist of household income, employment kind, number of dependents, housing conditions, and asset possession. Experimental consequences reveal that each algorithms are powerful in as it should be classifying eligibility for help, with k-NN barely outperforming Naive Bayes. therefore, the combination of these algorithms can support stakeholders in making extra goal and efficient selections regarding the distribution of social useful resource.

The development of automotive technology drives innovation in vehicle support components, including the continuously variable transmission (CVT) system, which plays a crucial role in transmitting engine torque and power to the wheels. One of the main elements in this system is the clutch lining and clutch housing, whose performance significantly impacts motorcycle performance. However, the standard pattern on these components is often not optimal in maximizing power delivery. Therefore, this study was conducted to analyze the effect of modifying the grooves of the clutch lining and clutch housing on engine torque in a 110 cc motorcycle. The research method used an experimental approach by varying the modification pattern on the clutch lining and clutch housing. The test motorcycle with a capacity of 110 cc was tested using a dyno test to measure torque and power at various engine speeds. Each modification variation was then compared with standard conditions to evaluate the resulting performance differences. The results showed that the pattern modifications on the clutch lining and clutch housing significantly increased torque. Several modification variations were able to significantly increase torque at medium to high speeds, thus providing better engine response and more efficient power delivery. Thus, this research contributes to the development of more optimal CVT component designs and has the potential to improve motorcycle performance, especially in the small capacity vehicle segment.  

This study aims to analyze how internal strategies and external challenges can influence the achievement of Regional Original Revenue targets at the Laboratory Technical Implementation Unit (UPTD) of the Public Works and Public Housing Agency (Dinas Pekerjaan Umum dan Perumahan Rakyat) of Cilacap Regency. The research object is the performance of the Laboratory Technical Implementation Unit (UPTD), a technical unit providing construction material testing services, which directly contributes to Regional Original Revenue in Cilacap Regency. The qualitative approach employed a case study method, and data collection techniques included interviews, observation, and documentation. The sample in this study was obtained purposively. The results indicate that internal strategies focused on superior testing methods such as core drilling, abrasion, and concrete compressive strength have been conducted. However, limited equipment, human resources, and the lack of accreditation are major obstacles. On the other hand, external challenges include the lack of updated Regional Regulation tariff regulations, the absence of formal obligations for the use of laboratory services for regional budget projects, and a saturated local market. These findings provide important implications for the Laboratory Technical Implementation Unit (UPTD) in emphasizing policy revisions, increasing internal capacity, and strengthening inter-agency coordination to increase Regional Original Revenue realization.

In the midst of increasing organizational competition, issues of low organizational commitment remain prevalent, including at the Office of Public Works, Spatial Planning, Housing, and Settlement Areas of Bali Province, as indicated by a high absenteeism rate and ineffective work behaviors. These problems are suspected to be influenced by inadequate training methods, low self-efficacy among employees, and a lack of job satisfaction. The present study explores the extent to which employee training and perceived self-efficacy contribute to fostering organizational commitment, with job satisfaction positioned as an intervening construct. Conducted within the context of the Public Works, Spatial Planning, Housing, and Settlement Agency of Bali Province, the research engaged a workforce population of 610 individuals. Through the application of the Slovin formula, a representative sample of 86 respondents was identified. Data were gathered through a combination of structured questionnaires, in-depth interviews, and document review. Analytical processing was undertaken using path analysis to model the causal relationships among variables. The empirical evidence revealed that both training initiatives and self-efficacy perceptions have a favorable and statistically significant relationship with employees’ commitment to the organization. These two factors were also found to positively affect job satisfaction. Furthermore, job satisfaction emerged as a critical determinant that reinforces organizational commitment. The analysis further supports the mediating role of job satisfaction, demonstrating that the influence of training and self-efficacy on organizational commitment is also conveyed indirectly through improved job satisfaction levels. The findings of this study highlight the importance of investing in employee development through effective training programs and boosting self-efficacy to enhance job satisfaction.

PT. Soemo Adjie Persada is a company engaged in housing development and is dealing with serious problems in warehouse material management. The manual and unstructured material recording system causes various obstacles, such as data discrepancies, input errors, and stockouts that hamper the smooth running of the project. This study aims to analyze and implement the Kanban system as a more efficient and accurate material management solution. The study was conducted using a qualitative descriptive approach through interviews, observations, and documentation methods.

Flooding is a natural disaster that still frequently occurs in Singkep District, Lingga Regency, Riau Islands Province. This disaster has quite serious impacts on the community, both in the economic, social, and health sectors. Therefore, the problem of flooding should be a serious concern for the local government, particularly in improving the effectiveness of coordination between agencies directly involved in flood mitigation efforts. This study aims to determine the coordination process between the Regional Disaster Management Agency (BPBD) and the Public Works and Spatial Planning Agency (PUTR) of Lingga Regency in flood management, as well as to identify obstacles encountered in its implementation. The research method used is qualitative with a descriptive approach. The researcher uses the coordination theory of Harold Koontz which emphasizes four important elements: work planning, meetings or interactions, communication, and division of tasks. Data were collected through in-depth interviews, field observations, and documentation from both related agencies. The results of the study indicate that inter-agency coordination has not been running synergistically. The work plans of each agency have not been fully integrated, resulting in the implementation of the flood mitigation program running independently based on their respective duties and functions. The Regional Disaster Management Agency (BPBD) places greater emphasis on non-structural mitigation approaches such as education and simulations, while the Public Works and Housing Agency (PUTR) focuses on technical aspects such as flood control infrastructure development. Inter-agency meetings remain formal and have not yet become collaborative forums for formulating joint policies. Communication and task allocation have occurred, but are limited to the information dissemination stage. Key obstacles to this coordination include budget constraints, a lack of competent personnel, and low public awareness and participation in supporting mitigation programs. The lack of drainage construction in several affected villages also demonstrates weak inter-agency integration in program implementation.

Tuberculosis (TB) is a contagious illness triggered by Mycobacterium tuberculosis, with transmission influenced by not only personal behaviors but also by the physical condition of the home environment. Environmental risk factors include flooring, wall material, ceiling structure, indoor temperature, humidity levels, air ventilation, habits of opening windows, and housing density. This research aimed to explore the correlation between individual behavior and the quality of home environmental conditions with pulmonary TB incidence in the Sematang Borang Health Center’s coverage area, Palembang, in 2025. A descriptive observational design was employed, involving 91 participants from Lebung Gajah Subdistrict. The sample consisted of both confirmed pulmonary TB patients (PCR positive) and individuals without TB (PCR negative), selected through purposive sampling. Data were processed using univariate analysis to describe frequency distributions and respondent characteristics. The study found that 35.2% of respondents were diagnosed with pulmonary TB, while 64.8% were not. Most participants were between 46 and 65 years old (42.9%), predominantly female (59.3%), and had a senior high school education (40.7%). In terms of TB-related knowledge and behavior, 59.3% had good knowledge, 63.7% held a positive attitude, and 50.5% practiced proper prevention measures. Nevertheless, more than half (56.0%) of the housing conditions failed to meet health standards for a safe home environment. These findings highlight that while the community shows generally good awareness and preventive behavior regarding TB, many still reside in environments that may contribute to TB transmission. Therefore, continuous health education, proactive contact tracing, and targeted health campaigns for at-risk groups—especially among those with lower educational backgrounds—should be prioritized.

The design of Lecturer Housing for Campus 4 Gorontalo State University is a strategic necessity in line with the expansion of educational institutions and the increasing number of educators requiring adequate and proximate housing. The primary objective of this research is to produce a lecturer housing design that is not only adaptive and sustainable, but also harmonized with the Regional Spatial Plan (RTRW) of Bone Bolango Regency. The research methodology encompasses a comprehensive site analysis, examining aspects such as climate conditions, topography, vegetation patterns, infrastructure and utility networks, ambient noise levels, and site accessibility. Furthermore, a zoning and spatial relationship study was conducted to determine effective space allocation based on the principles of tropical architecture and green building practices. The findings of the study highlight that a north-south building orientation significantly reduces heat absorption, while the integration of cross-ventilation strategies enhances natural airflow and thermal comfort. Spatial zoning into public, semi-public, private, and service areas allows for organized layouts and promotes social interaction among residents. Sustainability is reinforced through the application of green architectural technologies, including the use of green concrete, lightweight steel frameworks, solar energy panels, as well as integrated waste-water management systems that separate black water and grey water. Landscaping elements, both softscape and hardscape, are utilized to enhance aesthetics while supporting ecological balance and rainwater absorption. This design proposal contributes to the broader discourse of sustainable tropical housing and may serve as a replicable model for future lecturer housing projects in similar regional contexts. It emphasizes the importance of environmentally responsive, cost-efficient, and socially supportive residential architecture.

Musyarakah Mutanaqisah (MMQ) is a form of sharia-based financing that offers a home ownership solution free from elements of interest (riba). This article aims to analyze the application of the MMQ contract in housing finance, compare it with the conventional mortgage scheme (Kredit Pemilikan Rumah/KPR), and evaluate its impact on community welfare. This study employs a descriptive qualitative approach through literature review of academic sources, regulations, and other relevant data. The analysis shows that MMQ is superior in terms of compliance with Islamic principles, fairness in risk sharing, and flexibility in payment structure. Furthermore, the MMQ scheme contributes to the improvement of social and economic well-being, particularly for the lower-middleincome segment of society. Nevertheless, its implementation still faces challenges such as the risk of default and the need for strengthened risk management systems. Therefore, collaboration between Islamic financial j, the government, and the public is essential to optimize the potential of MMQ as a fair and sustainable alternative for home financing
