I. INTRODUCTION
Since the implementation of broad regional autonomy, real and responsible based on Law no. 22 of 1999 on Regional Government which was then replaced by Law no. 32 of 2004 and the most recent Law no. 23 Year 2014, boundaries between regions become a very important concern. In the era of regional autonomy, there are a lot of regional developments in both the villages, districts / municipalities and provinces that have split up. This has resulted in potential conflicts between regions and even a political impact on border areas. In practice, many local governments have difficulty setting borders. After the implementation of regional autonomy, problems that often arise both between autonomous regions and in an autonomous region is the issue of border area [1]. One of them is the boundary between Donggala Regency and North Mamuju Regency.
In the province of Central Sulawesi, there is a case of Ngovi Village area, this area boundary conflict arises as a result of the policy of regional border arrangement based on Kepmendagri   This study aims to provide a recommendation of the boundary line between Donggala Regency Central Sulawesi Province with North Mamuju Regency West Sulawesi Province. Boundary determination can be done using two methods: cartometric method (withdrawal on work map) and field survey method [2]. This research uses the cartometric method, this method can reduce the survey activity in the field which usually requires a large amount of funds and a relatively long time, especially in difficult terrain that is difficult to reach because of the natural barrier itself, making the work of technicalboundary conflicts can be done in a long time shorter without reducing the required accuracy.
Confirmation of boundaries is a definite boundary activity in the field. The border affirmation process focuses on the realization of clear and definite boundaries both from the juridical and physical aspects of the field and is done in order to determine the exact position and boundary position in the field up to the determination of the boundary coordinate point above the map [3].

B. Data and Material
Data required in this study were obtained from the Geospatial Information Agency (BIG) consisting of:

A. Results of Area Boundary Interpretation
The interpretation result of Kepmendagri coordinate no. 52 Year 1991 can be seen in Figure 3. Figure 3 shows the boundary line of Donggala District with North Mamuju Regency according to the interpretation of Kepmendagri no. 52 of 1991. The blue line represents the boundary through the river, while the brown line represents the boundary that passes through the ridge (contour). The drawing of Kepmen line is done by field survey method and cartometric method.

B. Results of the Limit Recommendation
In this research, the boundary maps of Donggala Districts and North Mamuju Districts can be used as recommendations for the settlement of the border disputes between the two regions. The area in this study was in the 50S zone. Boundaries can be drawn based on natural markers (eg river), artificial markers (eg roads), and other agreed boundary markers.
The results of this study are based on the Minister of Home Affairs Regulation no. 76 of 2012 on the confirmation of regional boundaries. As in the map contains some information such as administrative boundaries, the location of the point kartometrik and so forth. An alternative map of borders for more details can be seen in the appendix of this paper.
The analysis done in this research is to fix the boundary area according to Kepmendagri no. 52 year 1991 based on Permendagri no. 76 Year 2012. The following sample analysis on the boundary line:

C. Description of Area Borders Segment
The boundary line in this study is the legal boundary line (Permendagri 76/2012). The border line is guided by the Minister of Home Affairs Regulation no. 76 Year 2012 [2]. The resulting boundary is sourced from digital RBI data (contour, river, road) and Citra. The following table describes the description of each boundary line,  Obtained 15 points kartometrik spread on the boundary line of Donggala and North Mamuju. Table 2 and Table 3 show the area codes according to Permendagri No. 56 of 2015 on the Code and Data of Regional Government Administration. Figure 5 shows the distribution of the cartometric point on the alternate line. Table 4 shows the coordinates of kindergarten and numbering in kindergarten. According to Minister of Home Affairs Regulation no. 45 of 2016 Concerning Guidelines for Determining and Affirmation of Village Borders, for numbering of cartometric points is TK (provincial area code).
