The urban area of Sendawar Timur is part of the entire urban area of Sendawar, which is the capital of West Kutai Regency in East Kalimantan Province. According to the Regional Spatial Plan (RTRW) for the province of East Kalimantan, the urban area of West Kutai is designated as one of the Regional Activity Centers in the province of East Kalimantan. Therefore, in view of the authors involved in preparing the RDTR in the area, the urban area of Sendawar will be developed from a mediumsized city to a large city in the next 20–50 years, even though its current condition is still a small urban area with a population of less than 500,000 people.

The eastern part of Sendawar urban area is in the easternmost area of West Kutai Regency and is bordered by Kutai Kartanegara Regency with its border on the median line along the Mahakam River. As a whole, the Sendawar urban area as a whole does not yet have an RDTR that has been ratified as a Regional Regulation (Perda). In the previous several years, detailed planning had been carried out, but until the time of the preparation of the Sendawar Timur RDTR, the RDTR for the Sendawar urban area (as a whole) had not yet become a Perda.

By taking into account the various potentials, problems, and the carrying capacity and capacity of the planning area from various aspects discussed starting from the policy aspect, the position and role of the region, the physical condition of the area, population and sociocultural conditions, existing land use conditions, economic conditions, development finance, and various other aspects, including the opinions and aspirations of stakeholders, the structural plan, and spatial pattern plan, in the Sendawar Timur RDTR are as shown in **Figures 1** and **2** below.

In the planned service center system in the East Sendawar planning area, it is planned to develop a secondary center I for the whole Sendawar urban area. This development is very reasonable and possible because before the secondary center I was developed, which was close to the West Kutai Regency office center, the largest secondary center in the urban area of Sendawar was in this area, namely in the trade and service area near the Sendawar/Melak Islamic Da'wah Center. To this day, when the urban community of Sendawar needs goods for annual needs or non-daily needs that cannot be obtained at the secondary center I, which is near the district office center, they will make their purchases in this area. Therefore, it is very reasonable and possible that this area will also be developed as a secondary center I for the urban area of Sendawar as a whole.

Likewise, with the airport in the planning area, its utilization will also be maximized by developing an aero-eco city near the airport, which will also be developed into a secondary center II (under secondary center I, which is near Melak). Likewise, there is an opportunity that the Sendawar urban area will also be traversed by a railway line that is connected to Samarinda, so plans for an integrated terminal and station are also being developed in the area. This plan combines the opportunity for the railroad line, the determination as a Regional Activity Center, which will become a medium-large city, and the existence of a primary collector road that runs through the area.

The existence of an opportunity as a Regional Activity Center city in future is also used to develop the road network in the secondary system. Although in the RTRW of East Kutai Regency as well as in the RDTR concept for the Sendawar urban area, a road network in the secondary system has not yet been developed, the RDTR for the part of the Sendawar urban area in the eastern part, proposes to develop a road network in the secondary system in anticipation of Sendawar urban becoming a medium or large city, which acts as Regional Activity Center city for the East Kalimantan region.

Likewise, with the orientation of the movement of people who have been through the river and there are still many areas around the river that have not been built, plans are also being developed to build a secondary collector road that can connect the movement of people from secondary center to II with other II as well as between secondary center II and the other III is on the road, which is also an inspection road for the Mahakam River. This is also an effort to control the risk of flooding in parts of the area that are close to the river's lips. These various plans are outlined in the spatial structure plan and spatial pattern plan (besides other RDTR contents) as shown in **Figures 1** and **2**.
