Nusa Lembongan islands, Bali have a potential of coral reef diversity. Coral reefs have both ecological and high economic potential so that they are widely used. The economic benefits of coral reefs make these ecosystems very vulnerable to pressure from human activities. One of these human activities is the use of coral reefs in diving tourism activities. This research aimed to determine suitability and carrying capacity of coral reef ecosystem on Nusa Lembongan Island so that it can be recommended to manage coral reef ecosystem strategies to support the use of diving tourism. This study was conducted on six dive sites as observation points Observations on coral reef ecosystems were carried out using the intercept transect (LIT) method, and reef fish observation was carried out using the fish visual census method. Water quality sampling will be done in situ. Diving suitability was carried out by estimating the tourist suitability index (IKW) of six parameters, namely the brightness of the waters, coral community cover, coral life form, reef fish species, coral reef depth and current. The tourism suitability index value for the diving tourism category obtained was 74.07% (Jack Mangrove); 57.41% (Crystal Bay); and 61.11% (Manta Bay). The value for each observation point is included in the appropriate category of 50% -75%. It can be interpreted, that all observation points which are dive sites in Nusa Lembongan have supported diving tourism activities.Keywords: Tourism Suitability Index; Diving; Nusa lembongan.

Coastal ecosystem is a productive ecosystem and has high ecological and economic value. Coastal ecosystem components, consist of coral reefs, seagrass beds, mangroves and various types of biota. The seagrass ecosystem is one of the most unique coastal ecosystems because the seagrass can live well in high salinity conditions. Seagrass ecosystem in Bali Island has many adventages and widely used for marine tourism activities. One of the marine tourism sites, that take advantage of the beauty of the seagrass ecosystem in Bali is Sanur beach. The utilization of seagrass ecosystem for marine tourism activities might be influence the structure of seagrass community. Therefore, the study about Community Structure of Seagrass Ecosystem at Intertidal Area in Sanur Beach is very important to carried out in order to investigate the structure of the seagrass ecosystem community. Samples were taken in the intertidal zone at six observation stations. At each station, it was conducted three times perpendicular repetition to the shoreline. Seagrass observation was done by using quadratic transect (50 × 50 cm). The types of seagrass found in Sanur Beach were 6 species, namely Cymodocea serrulata, Cymodocea rotundata, Halophila ovalis, Halodule uninervis, Halodule pinifolia, and Syringodium isoetifolium. Cymodocea serrulata is a seagrass-type found in every observation station, and it able to live well in Sanur Beach water characteristics. The highest average of seagrass species density is shown by the Cymodocea serrulata species of 175.11 stands/m2, while, the highest average of seagrass species density is shown by the Halodule pinifolia species of 27.33 stands/m2. The average of diversity, uniformity and dominance index at Sanur Beach reach 0.8682; 0.7347; and 0.4987, respectively. In Sanur Beach area, the seagrass has high uniformity value and stable community. The instability community has been found at station 2 when the dominance of Cymodocea serrulata species was occurred.

Banyuwedang Bay is located in the West Bali National Park (TNBB), which is part of the conservation area. There were a lot of tourism activities developed in this area, which potentially caused disruption of the surrounding water conditions. This study aims to determine the profile of various communities in the waters of Banyuwedang Bay and as initial data to see the development of these communities due to the environmental impacts of various activities in the waters and coastal area of Banyuwedang Bay. Data was collected from five observation stations including: Community structure of Plankton, Macrozoobenthos, and seagrass, and coral reef cover. Result shows that the phytoplankton community consist of 9 genera where Nitzschia sp. (Bacillariophyceae) as the dominant species found. Phytoplankton have low diversity index ranging between 0.348 - 1.411. Zooplankton diversity index also has low value 0.693 with three genera found namely Copepoda sp., Nauplius sp. and Daphnia sp. Macrozoobenthos community is composed of 17 macrozoobenthos genera, with low diversity index ranging ??between 0.562-1.809. There are only two species of seagrass, Halophila ovalis and Cymodocea rotundata, which were found in Banyuwedang Bay. Coral reef cover seems to be ranged from poor to good conditions, with 25% - 73% coverage. Based on the result, we concluded that the Banyuwedang Bay has a moderate condition to the growth of plankton and seagrass, but good for coral reefs. Periodic monitoring is needed to find out changes in conditions that can occur in Banyuwedang Bay. Keywords: Banyuwedang Bay; community structure; macrozoobenthos

Macro debris refers to waste materials ranging in size from 2.5 cm to 1 m, commonly found both on the water's surface and on the seabed. The accumulation of such large debris in coastal and marine environments can lead to various consequences, including disturbances to ecosystem stability and threats to the survival of organisms. Additionally, it diminishes the aesthetic quality of the environment. Among the ecosystems most susceptible to becoming repositories for this waste is the mangrove ecosystem. This study aims to quantify the amount, types, and abundance of macro debris scattered in the Tukad Mati Estuary Mangrove Area, Badung Regency, Bali. The research methodology involved several steps, starting with the selection of research stations. Transects measuring 5 x 5 meters were established. Within these designated areas, samples of macro debris were collected and categorized according to their composition, including materials such as plastic, fabric, glass, metal, and rubber. The results revealed that the total mass of macro debris collected in the Tukad Mati Estuary area amounted to 42,630 grams. The types of macro debris found in the Tukad Mati Estuary mangrove ecosystem consist of plastic, fabric, glass, metal, and rubber. Based on their quantity, the composition of macro debris is dominated by plastic at 87.02%, followed by fabric at 4.24%, rubber at 4.17%, glass at 2.67%, and metal being the least at 1.89%. Based on their weight, the composition of macro debris is highest for plastic at 32.33%, followed by rubber at 27.29%, fabric at 20.23%, glass at 14.36%, and metal being the lowest at 5.78%.
