Abstract


Arrangement of the cultivation space is to regulate the utilization pattern and control of the cultivation space.  Cultivation space plan is carried out through the process and procedures for the preparation and determination of spatial plans based on the applicable and binding laws and regulations. This study aimed to (1) analyze the needs and availability of cultivation space that has been allocated based on the population of Gayo Lues District until the year of 2033 and (2) analyze the suitability of cultivation space utilization patterns based on space allocation in the Gayo Lues District Spatial Plan.  The research was done in Gayo Lues District, Aceh Province, from March to Oct. 2018.  Gayo Lues is located at 03º 40'26 "- 04º 16'55" N and 96º 43 '24 "- 97º 55' 24" E , with an area of 554,991 ha.  Materials and methods used included various thematic maps and imagery of Landsat satellites in 2016. In addition to the field observations, a survey tool in form of a global positioning system (GPS) was used, and Arc GIS 10.4 software was used for spatial data processing. The results showed the allocation of the cultivated area until the year  2032 was 160,017 ha.  This area is sufficient for the increase population up to 2032 of 1.69% annually. However, the used space was not so uniformly distributed that we still found three sub-districts were not yet fulfilled such as Blangkejeren, Blang Pegayon, and Putri Betung since 2016, and Kuta Panjang starting in 2020.  Based on the analysis of existing land use, we found a deviation of 1,482.30 ha of land use.  Land use deviations occur in all subdistricts, but the most deviated one was in Blangkejaren District, Dabun Gelang and Putri Betung. The deviation occurred was mainly due to the development of  Sere Wangi cultivation. Based on the agreeable forestry land (TGHK) criteria, we found the unused area of 37,000 ha of 160,017 ha, for cultivation. However, there is 50,000 ha outside the allocation of cultivation area could be used for cultivation land. It is suggested that the allocation of cultivation be revised before the year 2032.
