This study aims to examine the potential and challenges of utilizing Solar Power Plants (PLTS) in Medan City, which is geographically located near the equator and receives high exposure to sunlight throughout the year. The method used is a literature review with a narrative review approach that analyzes secondary data from various journals and relevant scientific articles. The results of the study show that Medan City has an average annual horizontal global solar radiation intensity of 463.61 W/m², with the potential for electrical power that can be generated from rooftop solar panels reaching 748.57 MW (monocrystalline), 598.85 MW (polycrystalline), and 299.43 MW (thin film). This potential is comparable to the capacity of large-scale power plants. The use of PLTS contributes to reducing carbon emissions, increasing energy security, creating jobs, and developing the local economy. However, challenges such as high installation costs, limited suitability of roof structures, and low public awareness are still major obstacles in the implementation of this technology. Therefore, synergy is needed between government policies, public education, and technological innovation to optimize the use of solar energy in urban areas such as Medan.

Green Open Space (GOS) plays a strategic role in modern urban planning, serving not only as an ecological element but also as a social, educational, and recreational space that supports the sustainability of urban life. Its presence is a vital necessity in addressing the challenges of urbanization and environmental degradation. This study examines and redesigns Taman Mandiri in Jayapura City as a sustainable urban park capable of accommodating various ecological and social functions. Field observations reveal that the existing condition of the park does not yet meet adequate public facility standards, such as the availability of interaction space, playgrounds, toilets, and parking areas. Through a sustainable landscape design approach, the park is directed to become an inclusive, efficient, and environmentally friendly green open space. The proposed design integrates the use of local vegetation, natural water management systems, and the enhancement of the park’s social functions. It is expected that this design can serve as a model for urban park development in tropical regions facing urbanization pressures and contribute to improving the quality of life in a sustainable manner.

The state's efforts to provide accurate and up-to-date population data for various development needs, such as planning policies and public services, are known as the implementation of population administration. Due to the large number of people living in big cities, many non-permanent residents have not been officially registered. This is due to difficult procedures, lack of legal knowledge, and limited access to population registration services. The need to maintain the basic rights of every citizen, both permanent and non-permanent, and ensure orderly administration as part of national development is the basis of the policies used to manage population administration. By ensuring proper data collection, accurate recording, and legal protection for non-permanent residents, proper population administration is expected to be an important tool to reduce the negative impacts of urbanization, especially in the city of Surabaya. This study aims to determine how population administration for non-permanent residents in the city of Surabaya is implemented in the context of urbanization and to suggest more reasonable and efficient policies. The results of the study, which was conducted using a qualitative approach by conducting literature research, in-depth interviews, and policy analysis, showed that simplifying registration procedures, increasing socialization, and increasing cooperation between related institutions are needed to carry out population administration for non-permanent residents.  

The rise in Value Added Tax (VAT) from 11% to 12%, which was put into effect in January 2025, has elicited a range of reactions from Indonesian households, particularly those in the urban middle class. This research intends to investigate the effects of the VAT change on consumption habits among this group. Information was gathered through a survey conducted with 400 households in Jakarta, Surabaya, and Bandung utilizing a stratified random sampling technique. A quantitative analysis was performed using multiple linear regression. The findings indicate that while the overall tax burden on basic consumption did not rise significantly due to various mitigating measures, the public's perception of the VAT hike still resulted in a decline in spending—particularly on non-essential items and services. This result underscores the importance of fiscal perception in influencing household consumption patterns. The study suggests that fiscal transparency, public awareness campaigns, and compensatory policies are essential for preserving middle-class purchasing power during initiatives aimed at enhancing national tax revenue.

Regional Regulation no. 1 of Bone Bolango Regency in 2024 concerning regional taxes and regional levies states in article 3 concerning PBB-P2 that Rural and Urban Land and Building Tax is a type of district/city tax, so that the Government has the authority to collect Land and Building Tax, especially the Urban sector.
