Climate change affects soil degradation, water, and crop. Thus, the adaptation of land management and crop rotation to minimize the impact of climate change is needed. Maize is an important commodity in Indonesia. Central Java province contributes to national production amounted to 40.07% during 2003-2015. In order to increase maize production, dryland farming becomes a good alternative. However, dryland is sensitive to erosion and a lack of nutrients. Thus, an adaptation of climate change can made by applying the conservation of both mechanic and vegetative. This study aims to evaluate the implementation and recommend alternative conservation improvement efforts on farming dryland maize in Central Java. The study was conducted in Central Java by using 270 respondents of dryland maize farm households in Wonogiri, Kendal, Tegal, Grobogan, Wonosobo, and Banjarnegara districts. Conservation Activity Index (CAI) is applied to describe the habits that have been carried out by farmers to preserve their farmland. The results showed that the CAI of maize farmers on dryland in Central Java Province is in the range of 43.5% to 95.7%, with an average conservation application of 75.08%. About 68.9% of farmers are in the medium of the CAI category. Evaluation result showed that conservation activities that are still weak in its application are vegetative conservation methods. Thus, we recommend increasing the cultivation of land cover and annual crops, and the use of mulch to enhance the conservation of dryland maize farming.
