Abstract: The existence of invasive alien species (IAS) in an ecosystem has become a global issue that continues to be discussed. Invasive plants led to the dominance of the crop in the fulfillment of competition for nutrients, water, light, and pollinated by pollinators. In Indonesia there are 27 IAS that is very dangerous and threatens the stability of the ecosystem. The introduction of IAS in Indonesia generally lowers production reached 20%, 1 individual IAS in the area of 0.1 m2 can reduce 57% of agricultural production. This aims to determine the introduction of IAS and its impact on agricultural. The method used is the analysis of vegetation, a literature review of national and international journals and complemented by interviews was conducted in June-October 2018 in Pacitan, East Java. Based on the research known biodiversity in the study site was (2.99) and Evenness medium (e ‘= 0.41) with the third-highest family Compositae (IVIs = 53.1), Poaceae (IVIs = 41.16), and Amaranthaceae (IVIs = 23.97). Cyperaceae and Compositae is the most dominant and is found throughout the agricultural types in the sites. Compositae is dominating (IVIs = 53.1). Alternanthera sessilis (IVIs = 23.97), Cyanthillium cinereum (IVIs = 1.45), and Ecinochloa colona (IVIs = 12.33). Based on the concept of IAS disturbance caused interference in terms of the type, intensity, spatial reach, frequency, and other factors are interspecific. According to the concept of disturbance the solution is control the growth and spread of IAS to save the ecosystem and agriculture sustainability.
