<p><em>One of seagrass dominant species found in Indonesia is <span style="text-decoration: underline;">Enhalus</span> <span style="text-decoration: underline;">acoroides</span>. This species can form single seagrass bed vegetation (monospecies vegetation) and mixed with others species (multispecies vegetation). Seagrass composition in coastal areas can be affected by surrounding associated species such as herbivorous fish and invertebrates. Human activities, especially in coastal communities, can negatively influence seagrass beds. Therefore, it is needed an effort to rehabilitate the affected seagrass. Transplantation technic is one effort for rehabilitation. The purposes of the research were to analyze growth rate, percent cover, and survival rates of seagrass <span style="text-decoration: underline;">E</span>. <span style="text-decoration: underline;">acoroides</span> transplanted as monospecies and multispecies. This research used a monospecies of <span style="text-decoration: underline;">E</span>. <span style="text-decoration: underline;">acoroides</span> and multispecies (2, 4, and 5 species) that combined to others species such as <span style="text-decoration: underline;">T</span>. <span style="text-decoration: underline;">hemprichii</span>, <span style="text-decoration: underline;">C</span>. <span style="text-decoration: underline;">rotundata</span>, <span style="text-decoration: underline;">H</span>. <span style="text-decoration: underline;">ovalis</span>, <span style="text-decoration: underline;">H</span>. <span style="text-decoration: underline;">uninervis</span>, and <span style="text-decoration: underline;">S</span>. <span style="text-decoration: underline;">isoetifolium</span>. Research results showed that the highest average growth rate of transplanted <span style="text-decoration: underline;">E.</span> <span style="text-decoration: underline;">acoroides</span> was found in monospecies treatment with 0.29 cm/day. The highest average cover changing was found on two combined species i.e., <span style="text-decoration: underline;">E</span>. <span style="text-decoration: underline;">acoroides</span> and <span style="text-decoration: underline;">C</span>. <span style="text-decoration: underline;">rotundata</span>, as high as 0.10% per day. The highest survival rates were found in 2 combined treatment i.e., <span style="text-decoration: underline;">E</span>. <span style="text-decoration: underline;">acoroides</span> and <span style="text-decoration: underline;">H</span>. <span style="text-decoration: underline;">ovalis</span>, and 5 combined species such as <span style="text-decoration: underline;">E</span>. <span style="text-decoration: underline;">acoroides</span>, <span style="text-decoration: underline;">S</span>. <span style="text-decoration: underline;">isoetifolium</span>, <span style="text-decoration: underline;">C</span>. <span style="text-decoration: underline;">rotundata</span>, <span style="text-decoration: underline;">H</span>. <span style="text-decoration: underline;">uninervis</span> dan <span style="text-decoration: underline;">H</span>. <span style="text-decoration: underline;">ovalis</span> with value 100 percent, respectively. </em></p><strong><em>Keywords:</em></strong><em> <span style="text-decoration: underline;">Enhalus</span> <span style="text-decoration: underline;">acoroides</span>, cover, growth, survival rates, seagrass, transplantation</em>
