ABSTRACT MANUSCRIPT HISTORY The development of population and infrastructure in cities can enhance the local economy, as seen in the Letda Sujono Road corridor. This area, located A between Medan City and Deli Serdang Regency and near the Bandar Selamat A Toll Gate, has seen significant growth in trade and service activities. This A growth has spurred the development of housing, public services, commercial A spaces, warehousing, and industry, increased land demand and causing A potential land-use conflicts and traffic issues. Inappropriate space utilization A can lead to urban sprawl, often due to inadequate spatial planning control. The Medan City Detailed Spatial Plan (DSP or Rencana Detail Tata Ruang (RDTR)) designates the Letda Sujono Road corridor as a Trade Sub-zone, with zoning regulations limiting some activities to 10% of the block area. Aims: The objective of this study was to study the suitability of existing activities with the zoning plan which has been regulated in the Medan City Detailed Spatial Plan as a space control content in order to create safe, comfortable and sustainable spatial planning. Methodology and results: This study uses a qualitative descriptive method with spatial analysis to assess the alignment of current activities with the DSP zoning plan. Conclusion, significance and impact study: The findings reveal that 60. of the activities are suitable, while 39. 16% are not. Some blocks, particularly Block 17-07-01 (Tembun. , have exceeded the 10% activity limit, indicating that zoning plans have not been fully realized, with unauthorized activities such as integrated schools and vehicle-related services still present.

Number 2, pp 129 Ae 148, 2024 INTRODUCTION 1 Background and problems The growth of a city's population and infrastructure greatly affects its economy, which in turn drives more urbanization and population increase. This creates a cycle that impacts the demand for urban land. Urban development is most noticeable in the expansion of infrastructure to support various community activities. As cities grow, they often see higher population density, more buildings, and better facilities that support social and economic life. However, as . noted, urban growth can also harm the environment, making it important to maintain a healthy living environment for long-term sustainability. The sub-districts of East Medan. Medan Perjuangan. Medan Tembung, and Medan Area are well-positioned to become Regional Service Centers in Medan City due to their strategic These areas contribute to the overall development of Eastern Medan. The proposed service level system includes interconnected transport hubs, city-scale trade and services, and residential development. The area has strong connectivity, and a hexagonal spatial structure is recommended to optimize community services . The urban activity service centers describe the locations, hierarchy, scope, and functions of these centers . Medan Tembung is designated as part of the Sub-City Service Center in MedanAos spatial plan. Located along Letda Sujono Road, it is a high-activity area influencing Medan CityAos border with Deli Serdang Regency. As the area grows, social and economic activities will increase, along with the need for utilities and facilities . The growth of trade and services boosts other sectors like housing and industry . This sector influences the cityAos structure by increasing land use for housing and changing the city's physical layout . Medan Tembung has seen significant growth in trade and services, with land dedicated to these activities increasing from 87. 17 hectares in 2003 to 103. 13 hectares in 2018. However, thereAos a 236-hectare gap between current land use and Medan City's Spatial Pattern Plan, which could negatively impact the city's growth . Urban areas often experience land use changes that donAot align with spatial plans, driven primarily by trade, services, and access to infrastructure . The misalignment between space utilization and the Regional Development and Town and Country Planning (DSP) laws is partly due to weak space regulation systems. Different uses of residential and business spaces require tailored spatial planning . The implementation of Doi: https://doi. org/10. 25105/livas.

Volume 9. Number 2, pp 129 Ae 148, 2024 DSP policies faces challenges, including low public awareness of zoning rules, uneven policy socialization, inadequate supervision, and ongoing violations . Traffic congestion in Medan City is caused by factors like poor public adherence to traffic rules, school traffic, illegal parking, and railroad crossings . The average delay at key intersections is 46. 80 seconds per vehicle, indicating unstable traffic flow . Increased commercial activities along Letda Sujono Road have worsened traffic, especially near large Letda Sujono Road, a main road at Medan CityAos border with Deli Serdang Regency, faces high traffic delays due to warehousing and logistics activities. Effective spatial control is needed to ensure that activities comply with conditions and are appropriately regulated in the trade sub-zone. Medan City has two key spatial regulations: Perda No. 1 of 2022, covering the cityAos spatial plan from 2022 to 2042, and Perda No. 2 of 2015, detailing the cityAos zoning regulations from 2015 to 2035. These laws guide space use in Medan and the issuance of permits for building approval. Letda Sujono Road is designated as a Trade Sub-zone in the cityAos spatial plan, with certain activities allowed under conditions or limited to 10% of the planned block However, this 10% limit has not been mapped, which is important for future evaluations of space use. This study aims to map existing activities against the trade subzone regulations on Letda Sujono Road. The results will help develop spatial solutions to control space use and guide revisions of Medan CityAos DSP regulations. 2 Literature Review The Medan City DSP Regional Regulation Number 5 of 2015 outlines the Detailed Spatial Plan and Zoning Regulations for Medan City from 2015 to 2035 . This plan guides how land should be used in different zones. Medan Tembung Regional Planning Section aims to develop a trade and business center and a sports service area over 779. 53 hectares. The trade zoning plan (K-. for Medan Tembung covers 80. 49 hectares in several areas, including Bandar Selamat and Tembung, mainly along Letda Sujono Road. The 2020 Job Creation Law (UUCK) introduced new spatial planning rules, specifically for the Conformity of Space Utilization Activities, now regulated regionally. However. Medan City's current DSP still uses older land use rules that need updating to align with UUCK. Despite the DSP's success in managing land use permits and coordination among agencies, challenges Doi: https://doi. org/10. 25105/livas.

Volume 9. Number 2, pp 129 Ae 148, 2024 These include a lack of public understanding of zoning rules, uneven outreach, inadequate land use supervision, and ongoing violations of DSP regulations . The zoning matrix (ITBX Matri. defines how land can be used within Medan City's Detailed Spatial Plan (DSP). It categorizes activities into four types: AuIAy (Permitte. , activities that can proceed directly unless restricted by other laws. AuTAy (Limite. , activities allowed with certain limits, like distance, area, or building specifications. AuBAy (Conditiona. , activities allowed only if they meet specific requirements, such as environmental or traffic impact assessments and resident approvals. AuXAy (Not Allowe. : activities that are not permitted at all. This matrix is used to ensure that any proposed space utilization aligns with the city's zoning rules. The expansion of trade and service activities has increased built-up areas, including commercial land and public facilities, while reducing open spaces . This growth impacts urban structure by increasing land use for housing and altering the layout of trade and service locations . Industrial activities, involving large vehicles, contribute to road congestion due to high traffic volumes and limited road capacity. Areas dominated by trade and services often see additional industrial and warehousing activities, further impacting transportation . With the rapid development of these areas, it's crucial to regulate activities by classifying them as permitted, restricted, conditional, or prohibited. Typically, permitted activities are smaller operations under 400 mA, while restricted and conditional ones involve larger lots between 400-5,000 mA and may operate for 16-24 hours. Prohibited activities generally require lots over 5,000 mA . The growing demand for space due to development is causing mismatches between how land is used and the original plans for its use. In urban areas, this often means more land is being used for trade and services . For example, a 2022 study by Mas Pratono and Rahmad Dian Sembiring found that in Medan Tembung District, trade and service areas grew from 87. hectares to 103. 13 hectares between 2003 and 2018, an 18% increase. This expansion, driven by Medan City's policies, has led to 69. 61% of the area being used in ways not aligned with the cityAos Spatial Pattern Plan, which could cause disorganized growth and urban sprawl. Land use mismatches are influenced by economic needs, housing demands, proximity to economic centers, road access, population density, and the availability of public facilities. Although tools like zoning regulations, licensing, and sanctions are in place to control land use, they are not always effectively enforced . Urban development is mainly driven by human activity, business growth, and transportation, which increase space demands and alter land use Doi: https://doi. org/10. 25105/livas.

Volume 9. Number 2, pp 129 Ae 148, 2024 A lack of proper infrastructure is a significant challenge in managing trade and service areas . Additionally, a 2019 study by Muhamad Iqbal Januadi Putra and team found that Serang City is experiencing the Urban Heat Island (UHI) effect, with temperatures reaching 32AC in the city center. This heat is spreading along road networks due to rapid development and increased human activity, posing risks to residentsAo well-being . RESEARCH METHODOLOGY In this research, the approach refers to the overall strategy used to collect and analyze data . The study aims to achieve its objectives using a qualitative descriptive method with a spatial exploration approach. The main variables are the zoning regulation matrix and spatial data, used to analyze the suitability of activities based on their area in hectares. The spatial variables include: existing space utilization activities. Zoning Plan/Space Pattern Plan DSP Medan City, and Block Plan in DSP Medan City. Secondary data sources, including: the housing, settlement areas, human settlements, and Spatial Planning Agency of Medan City, providing the Medan City Detailed Spatial Plan (DSP) document and satellite images. the Land Office of Medan City providing spatial data of land parcels. books relevant to the research. Data analysis is conducted using spatial analysis with the ArcGIS application. The analysis has two stages. First, satellite images are interpreted and digitized to identify current activities. Then, the digitized data is overlaid with the zoning map to check for mismatches between current activities and the zoning plan. The suitability of these activities is then assessed based on DSP regulations. The analysis also checks whether activities labeled as Limited (T) and Conditional (B) exceed the allowed 10% of the plan block area. This helps identify which plan blocks are within or beyond the limits. Finally, the analysis determines the suitability of activities in the trade sub-zone along Letda Sujono road.

However, the Trade Sub-Zone is not fully compliant with zoning regulations. This is evident from the presence of non-permitted activities, like integrated schools, and conditional activities, such as vehicle pools, workshops, and warehouses.

Out of these, 311 were allowed, 127 had some restrictions, 131 had specific conditions, and 682 were not permitted. Additionally, 203 of these interactions, which is 16. 24%, exceeded the 10% limit set by the zoning rules, with the High Density Residential (R-. zone showing the most violations, totaling 47 cases. The zoning plan shows that cultivated areas make up most of the land, covering 162. 04 hectares, while protected areas are much smaller at 5. 98 hectares. The largest protected area is in Block 17-07-02 Tembung, and the largest cultivated area is in Block 17-06-01 Bandar Selamat. High Density Residential (R-. zoning is the most extensive, covering 15 hectares. Among the 45 types of activities found in the study area. Single Houses are the most common, followed by Row Houses. Shops and stores make up a smaller portion of the When looking at how activities fit within zoning rules, there are 172 instances where activities cross into different zoning categories. Most of these are permitted activities, with a smaller number being limited, conditional, or not permitted. High Density Residential (R-. zoning has the highest number of crossovers. Activities that fit within 10% zoning proportion 44 hectares, or 8% of the study area. Most of these are in R-1 zoning and Block 17-0701 Tembung. In the trade subzone along Letda Sujono Road, 32 activities were found, with 26 Doi: https://doi. org/10. 25105/livas.

Volume 9. Number 2, pp 129 Ae 148, 2024 being permitted. Most of the land in this area is suitable for these activities, but there is some non-conformity. Overall, zoning in the Letda Sujono Road Corridor still has issues, particularly with activities that are not allowed or conditional. To improve regional planning, the study suggests addressing these issues to ensure zoning regulations are better implemented and more effective. To improve the zoning and planning in the study area, several actions are recommended: First, the Medan City Government should address the mismatches between current activities and zoning rules, particularly in the trade sub-zone along Letda Sujono Road. This will help ensure that land use complies with established regulations. Second, there should be a solution for handling the operations of shipping and freight services to prevent traffic problems, especially in areas near the borders of Medan City. Third, the findings from this study should be considered when updating Medan City's planning regulations. Finally, further research is needed to review other plan blocks beyond Letda Sujono Road to achieve a thorough understanding of spatial suitability across the city. REFERENCES
