Abstract

Kiluan Bay is a coastal region in Tanggamus Regency, Lampung Province, with a very high potential for tourism. Increased levels of tourists may have a negative impact on Kiluan Bay's natural resources, one of which is the accumulation of trash. The ecosystem at Kiluan Bay may be impacted by trash accumulation, especially plastics. If these issues are not properly handled, it will have an impact on the sustainability of tourism activities and the preservation of the environment. Even so, this will have an effect on the local economy. In order to reduce the negative impacts of tourism activities that are not environmentally friendly, it is thought that the concept of ecotourism needs to be implemented at Kiluan Bay. The purpose of this study is to establish ecotourism development strategies that emphasize community knowledge at the local level. Survey techniques and interviews with relevant persons were used to collect the data. The results of the data collection were analyzed using a SWOT analysis to determine the alternative strategies required to support the implementation of the ecotourism concept in Kiluan Bay. The research showed that Kiluan Bay's ecotourism development is positioned in quadrant V (Growth/Stable). This viewpoint suggests that the ecotourism development strategy in Kiluan Bay, Lampung, must take the most of the existing opportunities. Developing an ecotourism management approach in Kiluan Bay that involves the community directly is one strategy that had to be implemented.

Abstract

Staphylococcus aureus is classified as a pathogenic bacterium in humans and animals. S. aureus infection in humans can cause skin infections, and produce toxins that result in shock syndrome, foodborne disease, bacteremia, endocarditis, metastatic infections, and sepsis, while in milk-producing animals it can cause mastitis infection. Initially, S. aureus can be overcome with penicillin antibiotics but often develops time S. aureus becomes resistant to penicillin to cause new infections, namely the Methicilin Resistant Staphylococcus aureus (MRSA) which was first reported in 1961. One of the natural ingredients from the sea that has natural antibacterial content is seagrass or Cymodocea rotundata. Which is one type of seagrass in Indonesia that is included in the round type of grass. Cymodocea rotundata has bioactive components such as alkaloids, flavonoids, phenol hydroquinone, steroids, triterpenoids, tannins, and saponins that function as antibacterials. This study aims to determine the potential of seagrass Cymodocea rotundata as an antibacterial against Staphylococcus aureus bacteria. This research is experimental research using wells. Samples of Cymodocea rotundata seagrass came from the coastal waters of Ketapang and were converted into a simplified powder form with ethanol solvent. The results showed that the diameter of the inhibition zone formed ranged from 5.5 mm - 9.7 mm, the largest in the 40% treatment. Based on this research, it can be concluded that the extraction of seagrass Cymodocea rotundata has benefits as an antibacterial and potential in the field of pharmacology.
