<p align="justify">Shrimp farming in the southern coast of Bantul Regency is considered to cause environmental degradation, and reduced mangrove association due to logging for land conversion to shrimp farm land. Failure in pond management has worsened the problems. The existence of ponds is also considered to be the cause of decreasing the amount of agricultural crops around the shrimp pond. Therefore, the purpose of this study is to identify land use change, land use and analyze the land suitability for shrimp farming, agriculture and mangrove plant associations. Identification of land use using ENVI 5.3 software with Maximum Likelihood Classification method and 5.06% (55.85 ha) land use result for shrimp farms with category empty ponds of 3.16% (34.88 ha) and active ponds of 1.90% (20.97 ha) and as much as 8.31% (91.93 ha) of land used for agriculture. The land use is proved by groundtruthing using Kappa analysis method and obtained a result of agreement of 0.70 (good) for ponds and 0.60 (moderate) for agricultural land. The identification of land use change using Google Timelapse resulted from the dominant land conversion of sand and mangrove crops into shrimp ponds in 2007 and massive changes from 2011 to 2015. Land suitability was evaluated using ArcGIS 10.5 with overlay method. Evaluation of land suitability for shrimp ponds with an area of 634.82 ha, and suitability for non-paddy agriculture with total area of 84.32 ha. While the suitability for paddy field is spread with 148,58 ha of land area, and land suitability for plant association of mangrove with land area 616,42 ha. From the output of land suitability then measured the perception of the community using Likert scale and obtained the result of 64% (agree) to use the land as farming land, 59% (neutral) use the land as rice farming land, 77% (agree) use the land as farming land for agriculture non-rice, and 59% (neutral) make the land as an area of mangrove association. Therefore, it can be concluded spatially and percentage of society perception that coastal area of Bantul Regency is dominantly suitable to be utilized as shrimp farm.<p align="justify">
