Abstract

Teluk Nare, situated in North Lombok Regency, is a coastal region abundant in marine resources, serving as a hub for fisheries and marine tourism. This research seeks to evaluate the abundance and diversity of plankton as a measure of the ecological health of Teluk Nare’s aquatic environment. Sampling was conducted in February 2025 across ten stations using the purposive sampling technique. Water samples were collected with a plankton net, preserved using Lugol’s solution, and analyzed at the University of Mataram’s Hydrobiology Laboratory. The findings revealed 18 plankton genera from seven classes, with Coscinodiscus, Copepoda, and Nauplius being the most prevalent across all stations. Plankton abundance ranged from 12,000 to 32,333 cells per liter, with the highest concentrations observed near river estuaries. The diversity index indicated moderate levels (1.67–2.08), the evenness index was high (0.71–0.89), and the dominance index was low (0.16–0.26), suggesting no single dominant species and a relatively stable ecosystem. Factors such as currents, salinity, and water transparency were found to influence plankton distribution and abundance. These results offer valuable insights for the sustainable management of Teluk Nare’s coastal ecosystem.

Abstract

The coastal area of Gili Trawangan, a prominent tourism destination, is facing increasing ecological pressure due to intensified tourism activities and population growth. This study aims to analyze the distribution and composition of macro debris along the coast of Gili Trawangan, North Lombok Regency. This study used transect and quadrat methods, as well as marine debris classifications according to NOAA and Tangavoa Blue. The results showed that the highest amount of waste was plastic (71%), followed by glass (13%), and ceramics (8%). The highest waste distribution was found at the port (62kg) and tourist areas (30%). These findings highlight that inadequate waste management and low public awareness significantly contribute to coastal pollution. Therefore, an integrated waste management strategy and increased public participation are urgently needed to preserve the marine ecosystem of Gili Trawangan.

Abstract

Plankton has an important role for aquatic ecosystems, especially in the food network in a waters. This study aims to assess the abundance and diversity index of plankton in Sire Beach, North Lombok Regency. The study was conducted in September 2019 using purposive sampling with 9 sample points. The water sample was filtered using plankton net then put into the sample bottle for identification in the laboratory. Shannon-Wienner Index was used for determining diversity of plankton species. The types of plankton found were 12 genera of phytoplankton from the Bacillariophyta group, including: Biddulphia, Coscinodiscus, Cocconeis, Cylindrotheca, Diploneis, Fragilaria, Gyrosigma, Licmophora, Navicula, Nitzschia, Pleurosigma, and Triceratium. The highest abundance of phytoplankton belonged to Coscinodiscus species as many as 1.380 cells/l at station 2.3. The high abundance of Coscinodiscus might be due to a nutrient supply in these waters. Seagrass ecosystem was thought to have an important role in obtaining nutrients for phytoplankton. Diversity index has a value which ranges between 1.117505-1.841236 showing that it is in the medium category. The uniformity index ranges from 0.450718-0.673373 indicating that the distribution of plankton species in each station is even. The dominance index ranges from 0.233508-0.522215. This shows that there is no type of plankton that dominates the waters of Sire Beach. This is due to the abundance of plankton species at each station which is fairly evenly distributed.

Abstract

The Olive Ridley Sea Turtle population in Indonesia continues to decline due to natural and human factors. So it is necessary to conserve it so that its population does not become extinct. One of the conservation areas that protect sea turtle eggs is in the Kurma Asih Conservation Area, Perancak Village, Jembrana Regency, Bali. This study aims to observe and collect physical data on beach habitats that are considered suitable as sea turtle nesting habitats and collect data on Olive Ridley Sea Turtle tracks and nests in Perancak Village. Data collection is done by going directly to the field (monitoring) to find out the location of nesting turtles. The data required are beach characteristics, characteristics of nests and potential predators of eggs and turtle identification. The results showed that the characteristics of the turtle nesting beach were that there were 7 types of vegetation identified such as waru trees, coconut trees, pandanus trees, katang-katang plants, weeds, bushes and rolling plants, the texture of the beach sand sediments was fine and black in color. 19 individual Olive Ridley sea turtles were found, with 22 nests, and 23 turtle tracks. There are human and dog footprints around the coastline that are potential predators for sea turtle eggs. The results of this observation can be recommended to those who need to keep the location well maintained, so that sea turtles will always land

Abstract

Water characteristics such as currents at Sedayu Beach, Penghulu Agung Beach, and Kuranji Beach have a role in transporting marine waste. Likewise, with the ebb and flow of sea water, the tides will bring marine waste towards the coast so that a lot of rubbish will accumulate on the coast. The dominant type of rubbish is plastic rubbish, which is the type of sea rubbish that is most commonly found on Kuranji Beach at 0.64 pcs/m², for Penghulu Agung Beach. as much as 0.84 pcs/m², and Sedayu Beach as much as 7.4 pcs/m², of the total three marine waste reports from research results related to types of marine waste in Indonesia itself, the composition of plastic waste has continued to increase by 5-6% since 2000. According to data from the Plastics Industry Association Indonesia and the Central Statistics Agency in 2018, plastic waste in Indonesia reached 64 million tons per year, and 3.2 million tons of it was thrown into the sea.

Abstract

Swage Bay is widely used as a fishing cultivation location. This activity is supported by looking at the fertility level of the waters such as looking at the presence of phytoplankton types. This research aims to determine the composition of phytoplankton types. The method used was purposive sampling, by taking 15 sampling locations. Then it is filtered using a plankton net and given Lugol's solution as a preservative. The results showed that there were 15 species found with 12 species from the Bacillariophyceae group and 3 species from the Dinophyceae group. The most common type of phytoplankton found at station 2 was Amphisolenia sp (117 cells/L). The highest total abundance of phytoplankton was at station 1 at 240 cells/L. The high number of Amphisolenia sp species in all stations is thought to be due to the observation location being close to the river estuary which has sufficient nutrient content to meet growth. The ecological index is the highest diversity index at station 11 (2.12), which indicates moderate diversity status. The highest uniformity index is at stations 5 & 6 (0.97) which indicates the high uniformity category. The highest dominance index value is at station 2 (0.6), which indicates that there is a dominant species. The Amphisolenia sp type is thought to be able to adapt to any type of aquatic environment.
