Abstract

Batu Kijuk Beach is one of the coastal areas located in West Nusa Tenggara. Its territory used for a tourist attraction and crossing to Gili Nanggu, Gili Gede and Gili Kedis. These coastal have a wealth of marine life, one of them is mollusc. This study aims to analyze the structure of mollusk community using the Systematic Plot Sampling method. This research was conducted in June-September 2019 in Batu Kijuk, Sekotong District, West Lombok, NTB. Identification and data analysis was carried out at the Marine Biology Laboratory, University of Mataram. From the results of research with 10 transects and 70 quadrants, there are 79 species with a total of 927 species of molluscs. The gastropod class consists of 65 species and 14 species of bivalves. The most common types of species found were from the family Columbellidae with 262 species, nassaridae 109 individuals, strombidae 82 species, cypraeidae 58 species and the rest were found 1-15 species. From the results of data analysis calculations, it was obtained that the highest abundance was Pyrene versicolor (3.70 Ind/m2), Nassaridae which was dominated by Hebra nigra with 2.91 (Ind/M2) and Nassarius globosus had an abundance value of 1.08 (Ind/m2). The index value of diversity (H') for molluscs in Batu Kijuk coastal is included in the high category, 2.74. The dominance index value (C) is 0.1 which means that no mollusk species dominates. The uniformity index (E) has a value of 0.62 which means moderate uniformity because only a few species dominate so that the community can be said to be quite stable.

Abstract

Microplastics (MPs) have become an interesting topic of discussion especially after many studies reported their presence in aquatic ecosystems. Pollution by microplastic particles in aquatic systems is a critical issue the world that has the potential to damage aquatic ecosystems. Therefore, this study aims to identify the abundance and characteristics of MPs in water, sediment and seagrass in tourist areas. Samples were obtained from three location categories, first the port, second the hotel area and third the residential area located in the Gili Trawangan tourist area, Lombok, Indonesia. After optimization of extraction, characterization was carried out using a stereo microscope to identify MPs. The results show that the average abundance of MPs in the three location categories is, 13.25 ± 17.21; 19.25 ± 23.30; and 16.50 ± 18.52 particles/L at water, 22.00 ± 30.84; 20.00 ± 30.80; and 6.00 ± 8.49 particles/kg dry weight (dry weight) sediment, and 17.50 ± 15.69; 16.25 ± 22.56; and 8.25 ± 8.46 particles/individual at seaweed. Then from this abundance, the types of MPs were found in the form of fragments, fibers, films and pellets, where the dominant colors are black, yellow, blue, red and green, with the highest size < 500 µm. From this study it is necessary to see the impact of MPs on seaweed and the aquatic environment around Gili Trawangan.

Abstract

The Sasak tribe, who are the indigenous inhabitants of Lombok Island, use banten (Lannea coromandelica (Houtt.) Merr.) leaves as a medicinal plant to reduce fever. Fever is a physiological response to infection, characterized by a body temperature above the normal range of approximately ± 37 ℃. If left untreated, fever can cause dehydration, lack of oxygen, nerve damage, dizziness, decreased appetite, weakness, and muscle pain. To minimize these effects, antipyretics such as paracetamol can be used. However, prolonged or excessive use of paracetamol can cause hepatotoxicity, hepatic necrosis, renal tubular necrosis, and hypoglycemic coma.  Therefore, it is necessary to develop alternative herbal medicines to treat fever. The aim of this study is to determine the content and antipyretic effect of banten leaf extract, which was obtained through ethanol extraction. The antipyretic ability test utilized five groups: the negative control group, positive control group, and test groups receiving doses of 1 mg/25gBB, 3 mg/25gBB, and 10 mg/25gBB of ethanol extract of banten leaves. Fever induction was induced using the DPT-HB vaccine. The study found that the ethanol extract of banten leaves contained flavonoids (572.38 mg QE/gram extract), phenols (200.82 mg GAE/gram extract), and antioxidants (2.5063 mg GAE/gram extract with DPPH). The percentage of antioxidant inhibition in banten leaves between 9.68-47.16 %. Additionally, all test groups of the ethanol extract of banten leaves exhibited antipyretic activity. The antipyretic effect of the 3 mg/25gBB dose was equivalent to that of paracetamol. Similarly, the antipyretic effect of the 10 mg/25gBB dose was almost identical to that of paracetamol at 5 hours after treatment.

Abstract

The West Sekotong coastal area, which includes mangrove, seagrass, and coral reef ecosystems, is rich in marine biota, particularly phytoplankton communities. These ecosystems have been designated as conservation areas; however, increasing exploitation and disturbances in the region have impacted the presence and distribution of phytoplankton. This study aimed to assess the distribution, abundance, and species diversity of phytoplankton across these three ecosystems. Using purposive sampling, phytoplankton communities were identified microscopically, revealing a total of 742 phytoplankton cells, with 264 cells in the mangrove, 258 cells in seagrass, and 220 cells in the coral reef ecosystems. The class Bacillariophyceae dominated across all ecosystems. Specific species dominance varied, with Skeletonema costatum prevailing in mangroves, Nitzschia sigmoidhea in seagrass, and Coscinodiscus radiatus in coral reefs. The highest similarity index (35.89%) was observed between mangrove and seagrass ecosystems, while the lowest (30.87%) occurred between mangrove and coral reefs. The species richness index (R) was high in all ecosystems, ranging from 6.45 to 10.26, and dominance indices were low, indicating a balanced community structure. Environmental parameters measured across the ecosystems showed no significant differences and met the quality standards for marine biota as per KEPMENLH No 51 2004.
