- Abstract
Sand dunes as an ecosystem have exceptional characteristics, such as those of the sand dunes of the Kretek Sub-District of Bantul Regency in the Special Region of Yogyakarta. The uniqueness of sand dunes is not only reflected by the conditions of the habitat but also by their unusual vegetation species, particularly the herbs. This research seeks to: 1) identify the herbaceous stratum vegetation on the sand dunes of Parangtritis, 2) discern herbaceous species with positive association, 3) distinguish negatively associated herbaceous species, and 4) gauge the potential of herbaceous species association on the Parangtritis sand dunes as a resource in learning biology. The sample was collected by means of quadrats and then analyzed with a 2x2 contingency table and Ochiai’s index. Results indicate both positive and negative associations in three different areas from the shoreline to the mainland. Combinations of herbaceous species tend to decline the further they are from the shore. The strongest positive association of herbaceous species was found in the combination between Tridax procumbens and Spinifex littoreus. These research findings potentially serve as biology learning material for grade X of high school in the topic of ecosystem structure and function.
