Spatial Distribution of Omah Alas, Tanjungsari District, Karst of Gunung Sewu

Amid the arid characteristics and limited soil and land resources in the karst area to support the agriculture sector, the settlers in it strive and establish Omah Alas settlement as part of the adaptation and livelihood. Nevertheless, the study on the spatial distribution of Omah Alas as a unique type of settlement where every single house is scattered in a distance and located in the field is very few. This study specifically examines the spatial distribution of Omah Alas in Karst of Gunung Sewu and the factors behind it. Specifically, this study takes place at the Kemadang and Banjarejo Village, Tanjungsari District, and targets the farmers for the population and using purposive sampling aims those who spend their daily life in their field. The data are obtained using field survey, interview, and observation for the primary data and Peta Rupa Bumi Indonesia (RBI) for the secondary data. Those data are analyzed using nearest neighborhood analysis and kernel density. The results show how the village setting influences the accumulation of Omah Alas while the Omah Alas spatial distribution is random due to the irregularity of landform in the study area. Land use and land ownership also affect spatial distribution.
