The rapid pace of population growth in coastal areas and increasing the need for natural tourism can have a negative impact on the quality and quantity of natural resources and the environment in Sepanjang Beach, Gunungkidul regency. The phenomenon of seawater tidal waves led to a number of buildings along the beach experiencing heavy damage. The purpose of this research is to know the environment carrying capacity seen from the aspect of land capability and land suitability aspects as a tourist area, as well as providing recommendations that are right on Sepanjang Beach. The methods used are spatial analysis methods using geographic information systems (GIS) and scoring methods to determine the environment carrying capacity and land suitability. The results of the calculation of the environment carrying capacity based on the aspect of land capability were obtained by 2 classes of land capability namely moderate and good. Whereas seen from the results of the suitability of the beach recreation category shows if Tourism Suitability Index (TSI) has a value of 94% which means it is appropriate. However, it is necessary to arrange the gazebo building to use upland land in the form of alluvial karst plain.

Sepanjang Beach is a tourist area located in Nglaos Hamlet, Kemadang Village, Tanjungsari District, Gunungkidul Regency. As a tourist area, this beach has a limiting factor that reduces the aspect of tourism in the form of a tidal wave that can endanger tourists. The tidal events that occurred on the coast The last one occurred on July 24, 2018 which caused 25 units of the gazebo to disappear and 115 units of the gazebo to suffer severe damage. So research is carried out with the aim of evaluating the ability of Sepanjang beach as a tourism area. Evaluation is done by scoring method. The parameters of land capability measured are soil texture, surface slope, drainage, depth of ground water, and erosion. The results of the calculation of land capability based on aspects of land capability obtained 2 classes of land capability, namely medium and good. Judging from the results of the land capability, the research location is considered to have a good level of land capability as a tourism area.
