Abstract

One of the recoverable coastal resources that can make a high contribution to the coastal environment and to coastal communities is the seagrass ecosystem. Seagrass is a flowering aquatic plant that has the ability to adapt to live in the marine environment. Seagrass has many functions, such as a nursery ground, a feeding ground and a spawning ground for fish and other biota that have high economic value. Various threats to the sustainability of the seagrass ecosystem in Indonesia continue to increase year after year. Commonly used seagrass transplant methods include the plug, sprig, tie sack and frame method. Kawaroe et al., (2008) stated that the method that produced the highest seagrass yield was the plug method. Likewise, Lanuru et al., 2013 found that the plug method resulted in a better survival rate compared to the staple and frame method. The success of a transplant method is also largely determined by the characteristics of the substrate at the transplant site. According to Lanuru (2011), the sediment characteristics consisting of fine, muddy sand are better than coarse sand and less muddy as a substrate for Enhalus acoroides seagrass transplantation.

Abstract

The technique of remediation of heavy metal contaminated soil can be done biologically with the help of microorganisms. Bioremediation is a soil remediation technique that uses enzymes from microorganisms in an effort to rehabilitate soil. The bioremediation mechanism occurs when enzymes derived from the activity of microorganisms interact with heavy metals in the soil and then convert them into uncomplicated chemical structures so that the level of heavy metal toxicity decreases. Among biological agents, enzymes have great potential to effectively convert and detoxify pollutant substances because enzymes have been recognized to be capable of converting pollutants at detectable levels and are potentially suitable for restoring polluted environments. Eco-enzyme is a fermented liquid produced from the composition of fruit/vegetable organic waste, water and brown sugar, which is an alternative product in helping the process of soil biodegradation. Eco-enzymes contain hydrolytic enzymes that can increase soil fertility and can be used as an effort to degrade heavy metals in polluted soil.
