Along with the development of Batu City as a tourist city, it is feared that there will be an increase in land use conversion from apple orchards and other agricultural land into residential and tourism land. The rate of land use change must be controlled to maintain environment sustainability. One of the effort is studying the change that occurred in the past few years. The purpose of this study were to observe land use change pattern that occured in 2006, 2012, and 2018, and to predict the land use at 2030 in Batu City. Land use prediction was evaluated with Markov – Cellular Automata models. The analysis showed that forest area decreased up to 5% and the built area increased up to 5.2% from 2006 to 2018. Prediction of land use in 2030 showed that there will be a decrease in forest, agriculture, and bareland areas, and an increase in shrubs and built areas. Agricultural land needs to be directed to be protected or conserved, while shrubs and open land need to be directed into potential land for apple orchards development in Batu City.

Pidie is one of the districts in Aceh Province that has been suffering from flooding. Frequent disasters, especially flooding associated with various causative factors, need mitigation efforts. An appropriate land use planning by considering the risk aspects especially in flood is an important step. Objectives of this study are to determine the factors influencing the flood hazard, to map the areal distribution vulnerable to flood, to analyze the relations of land use in the flood hazard area, and to analyze the relations between the planned spatial pattern and the flood hazard area. ,Multicriteria analysis was used to determine the factors influencing the flood hazard. Spatial analysis was used in mapping the class of flood hazard, the relations of land use in the flood hazard area, and the relations between the planned spatial pattern and the flood hazard area. The results show that the main factors influencing flood vulnerability are land use/cover (0.408), rainfall (0.266), and slope (0.184). Based on the classification of flood vulnerability, the area can be divided into more vulnerable (37.75 %), less vulnerable (30 %), and mildly vulnerable (22.76 %). The vulnerability classes of the land use/cover are: less vulnerable (99.99 %) and more vulnerable (97.57 %) dominated by forest cover; mildly vulnerable (51.07%) and vulnerable (92.65%) dominated by mixed farming; and very vulnerable (97%) dominated by settlement. The flood vulnerability of the planned spatial pattern can be classified as follows: 95.44 % of the conservation area is dominated by less vulnerable and more vulnerable, while 71.20 % of the cultivation area can be categorized into mildly vulnerable, vulnerable and very vulnerable.
