This study explores the relationship between smoking habits, hemoglobin levels, and awareness of carbon monoxide (CO) risks among street cleaning workers. Smoking is one of the most common sources of CO exposure, which can bind to hemoglobin and reduce oxygen transport in the body. A total of 67 street cleaning workers in West Jakarta were involved in this research, using a descriptive analytic approach. Data were collected through blood tests for hemoglobin levels, as well as interviews and questionnaires to assess smoking habits and knowledge of CO. The findings show that most respondents were light smokers (1–10 cigarettes per day), and 43% had been smoking for less than five years. While 66% of participants had normal hemoglobin levels, 33% had elevated levels, which may reflect the body’s response to reduced oxygen availability. Interestingly, 70% of respondents were aware of the health risks of CO, but knowledge tended to decline among long-term or heavy smokers. This indicates a gap between behavior and risk awareness. The study highlights the need for ongoing health education targeted at outdoor workers to increase understanding of CO exposure and prevent potential health impacts.

This study examines how colonial power is articulated through the form, spatial layout, and symbolism of Bogor Palace, and how post-independence transformations in function and discourse shape its new identity. As a colonial architectural legacy, Bogor Palace holds historical significance and reflects power dynamics, cultural representation, and spatial acculturation in both colonial and postcolonial contexts. The research highlights the importance of reassessing colonial architecture as a medium for representing power and ideology, especially in buildings that remain national symbols. Using a qualitative approach with literature review and visual analysis, the study applies Michel Foucault’s theory of power and discourse to reveal embedded power structures, and Erwin Panofsky’s iconography and iconology to decode visual symbols and meanings. Findings show that the neoclassical European style of the palace reflects colonial dominance, yet its adaptation through local materials, construction techniques, and climate-responsive elements indicates a complex process of acculturation. Initially marginal, local culture becomes integrated into the building’s design. After independence, the palace was resemanticized from a colonial icon to a national emblem, illustrating a shift in identity and power narratives. Today, restoration efforts not only preserve its historical value but also reaffirm role as a dynamic cultural space shaping Indonesia’s collective memory.

Nowadays, groundwater in the world has been widely exploited along with the increasing population. One of the impacts of massive groundwater extraction is the decline in groundwater levels. This potential could occur at one of the airports in East Java which is one of the most crowded airports in Indonesia. The large number of passengers at the airport has increased groundwater extraction due to the increasing need for sanitation, airport facilities, and other operational needs. This study aims to determine the potential for groundwater level decline at one of the airports in East Java. The research method used is a quantitative method by projecting secondary data from the results of groundwater level sampling carried out every 6 months. The results of the study showed a decline in groundwater levels at one of the airports in East Java in the next 20 years due to the increase in passengers each year. The results of this study are expected to be one of the preventive steps for all of us to maintain the sustainability of groundwater resources.
 

This study aims to describe in depth the role of teachers in shaping the religious values of grade IV students at the Ash-Shiddiiqi Integrated Islamic Elementary School (SDIT) Jambi City. Religious values are an important part of the formation of children's character from an early age, especially in the Islamic-based school environment. This study uses a qualitative descriptive approach. Data collection techniques are carried out through observation, interviews, and documentation. The results of the study show that teachers play a major role in the formation of religious values through example, habituation, integration of religious values in learning, and cooperation with parents. The formation of religious values is not only carried out in the classroom, but also through school activities with Islamic nuances such as congregational prayers, memorization of the Qur'an, and daily prayers. The success of religious character formation is greatly influenced by the consistency of teachers and support from the school and family environment.

Taxes are the main fiscal instrument in modern states, serving various strategic functions such as budgeting, regulation, stability, and income redistribution. Taxes are not only a source of state revenue but also a tool to encourage economic growth and the equitable distribution of welfare. In the context of Islamic economics, taxes have a different position but are not fundamentally contradictory. Islam recognizes the concept of levies such as zakat, kharaj, jizyah, and ushr, which have similar objectives to modern taxes, namely for the welfare and social justice. This research uses a qualitative method with a literature study approach to analyze the alignment between the function of taxes in modern states and the principles of Islamic economics. Data were collected through a literature review from relevant academic sources. The research results show that although there are differences in mechanisms and characteristics, there is a common ground in the main goal, which is the welfare of society. Taxes can be accepted in Islamic economics as long as they are collected fairly, transparently, proportionally, and used for the public good. Further analysis indicates that the principles of maqashid sharia can serve as an important reference in modern tax reform to better align with Islamic values. The conclusion of this study emphasizes the importance of integrating Islamic economic principles into the tax system to create social justice, fiscal efficiency, and sustainable development. This research is expected to provide theoretical and practical contributions to the development of a tax system based on Sharia values in the contemporary era.

This study aims to analyze the pricing mechanism based on sharia economic principles implemented at Ayukdiah Store in Sangatta Utara. The research employed a descriptive qualitative method with a case study approach. Data collection techniques included observation, interviews, and documentation. The findings reveal that the pricing at Ayukdiah Store combines cost-based pricing and competitor-based pricing methods, while adhering to sharia principles such as tawhid, justice, accountability, honesty, mutual consent, and the prohibition of usury. This strategy not only maintains business competitiveness but also builds customer loyalty and avoids unethical business practices.

Inequality in wealth distribution is a serious problem in the modern economic system. The gap between high and low income groups continues to widen, triggering various social problems. In the perspective of Islamic economics, zakat, infaq and waqf are present as instruments that not only have worship values, but also significant social and economic functions. This study aims to analyze the contribution of these three instruments in reducing the inequality of wealth distribution in society. Through descriptive qualitative approach and literature study, this research examines various literatures and secondary data obtained from zakat, infaq, and waqf management institutions in Indonesia. The results show that zakat, infaq, and waqf are able to act as effective wealth redistribution tools, improve the welfare of vulnerable groups, and strengthen social cohesion. These three instruments are proven to be a systemic solution in creating a more equitable economic balance. Therefore, accountable, professional, and trustworthy management is needed so that the socio-economic potential of zakat, infaq, and waqf can be optimized in supporting the creation of social justice according to Islamic teachings.

This policy proved effective in instilling healthy living values through structured physical activities and supporting the strengthening of character education

This study aims to analyze the endurance and stamina on the performance of a specific football athlete tarkam. Modern football demands peak physical condition, where endurance and stamina are key success factors. Endurance enables athletes to maintain game intensity for a full 90 minutes and recover quickly, while stamina supports repetitive sprints and physical duels. The research method employed is a qualitative case study approach, involving interviews, and data analysis from the selected football athlete. The findings indicate that high levels of endurance and stamina positively correlate with improved athlete performance, including passing accuracy, running speed, and decision-making ability under pressure. Conversely, fatigue resulting from low endurance and stamina negatively impacts game quality. The implications of this research highlight the importance of integrated training programs to enhance endurance and stamina for optimizing football athlete performance

Character education through sport is becoming increasingly important in the face of dynamic socio-cultural change. The sociology of sport offers an approach to understanding sport as a social phenomenon that has a broad impact on youth character building. This research uses a descriptive qualitative method to explore the role of sport in youth character building through a sociology of sport approach. The results showed that sport can be a medium for socialization, value internalization, and identity formation. Participation in sports activities can form a physically healthy, mentally strong, and morally sound young generation. However, sports can also be a space for reproduction of negative values if not balanced with constructive social values. Therefore, the sociology of sport approach can offer strategic solutions in designing sports programs that not only pursue achievements, but also form Indonesian people with character. This research is expected to contribute to the development of character education through sports and increase awareness of the importance of the sociology of sport in shaping young people with character and integrity.
