Abstract

One of the most abundant kinds of organism that lived in coral reef ecosystem are fish. Fish rely on coral reefs for shelter, food, and breeding grounds. Lombok is one of the islands that have many hotspots of coral reef ecosystem, one of which is at Pandanan Beach. The precense of fish benefits in both tourism and local economy, however the data about reef fish that lived in Pandanan waters are less known. This research aimed to assess the community structure of fish species in coral reef ecosystem at Pandanan Beach. The method that was used for sampling were UVC (Underwater Visual Census) with BIT (Belt Intercept Transect) technique at three different stations. The results showed 554 individuals which consist of 34 species from 12 families had been identified. The community structure of fish in the three stations showed the moderate level of diversity, stable evenness index with low dominance, and density value of 0,73. Environmental parameters measurement indicate Pandanan waters are suitable for fish growth and survival.

Abstract

The high level of construction and community activities at Kecinan Beach can affect the condition of the coral reef ecosystem. The health condition of the coral reef ecosystem can be assessed by the percentage of live coral cover within the ecosystem. North Lombok is one of the regencies on the island of Lombok that has experienced coral reef ecosystem damage, with this regency having the lowest percentage of live coral cover compared to other regencies. This study aims to determine the diversity of coral reef lifeform types and assess the health status of coral reefs at Kecinan Beach, North Lombok Regency. Data on coral reef lifeform types were observed using Coral Finder 2.0 Indo Pacific. Data collection was conducted using the UPT (Underwater Photo Transect) method at two different depths: 1-5 meters and 6-10 meters. The research results indicate that the coral reef ecosystem at Kecinan Beach is in poor condition. The percentage of live coral cover at depths of 1-5 meters is 3,58%, and at depths of 6-10 meters is 0,90%. There is ten types of coral reef lifeforms were found distributed across both depths: Acropora branching, Acropora tabulate, coral branching, encrusting, foliose, heliopora, massive, millepora, mushroom, and submissive. Diversity, evenness, and dominance indexs shows even distribution of lifeforms with no dominant species in the coral reef ecosystem at Kecinan Beach, North Lombok.

Abstract

Seagrass is a flowering plant thriving in shallow sea waters and estuaries. Seagrass ecosystems are essential in supporting life in shallow seas as primary producers, biota habitats, sediment trappers, and nutrient trappers. Environmental factors affecting seagrass growth include temperature, salinity, pH, and substrate. The study was conducted in March-June 2023. This study aimed to determine the type and condition of seagrass beds in the waters of Siwak Bay. The method used in this study is the quadrant transect method at three research stations. There are seven types of seagrass identified, namely Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, Cymodocea serrulata, Halodule pinifolia, Halodule uninervis, and Syringodium isoetifolium. The percentage of total seagrass cover is at a value of 37%-61%, indicating that the condition of seagrass beds in the waters of Siwak Bay is included in the unhealthy category. The highest species density found at station III in Halodule pinifolia was 483.5 stands/m², and the lowest was found at stations II and III in Thalassia hemprichii and Cymodocea serrulata with 0 stands/m². The average density value of seagrass beds in the waters of Siwak Bay is very dense. The highest type frequency was found in Cymodocea rotundata, with a value of 2.53. The tallest species diversity and diversity index was found at station II with values of 1.56 and 0.8, respectively. In contrast, the highest dominance index was found at station I, with a value of 0.44.

Abstract

Various natural resource utilization activities on the coast of Gerupuk Bay can potentially affect the quality of the aquatic environment, both biotic and abiotic, one of which is mollusc biodiversity. This study aimed to determine the relationship between the existence of Mollusca biodiversity and water quality and substrate in Gerupuk Bay. This study used a quantitative descriptive method of determining stations using the purposive sampling method based on differences in community activities at each station. Sampling was conducted at three stations, including Mollusca samples and water quality measurements: salinity, pH, temperature, and substrate. Molluscs in Gerupuk Bay found 55 species of Mollusks representing three classes, namely the Gastropoda class, with as many as 44 species incorporated in 22 Families; the Bivalve class, as many as ten species contained in 6 Families; and the Scaphopoda class, with as many as one types incorporated in 1 Family. The composition of Mollusca classes found on the Gerupuk Bay Coast is Gastropoda class at 62%, Bivalve class at 35%, and Scaphopoda class at as much as 3%. Mollusca diversity is calculated using the Shannon-Wienner diversity index (H'). The diversity index results ranged from 2.890-1.998, with moderate categories at all stations. Bioindicators of water quality using the diversity index show that stations I and III categorize the Gerupuk Bay area as lightly polluted. In contrast, at station II, it is moderately polluted.

Abstract

Rivers are water bodies in open ecosystems where activities in the environment have an impact on river water quality. Monitoring of water quality is necessary to preserve aquatic resources. One of the river basins on Lombok Island is the Jangkok River. This river has a high utility, so water quality monitoring is needed. Macroinvertebrates are one of the best biological indicators for water quality monitoring. The objective of this study is to determine the diversity of macroinvertebrates and the quality of Jangkok River waters by using macroinvertebrates as bioindicators so that the results of this study can be used as a reference basis for the future use of Jangkok River water in the allocation of community needs. The method used in this research is biomonitoring with macroinvertebrate bioindicators, and the technique used in sampling is purposive sampling. Sampling was conducted at three stations, namely the upstream, middle, and downstream parts of the Jangkok River. The data analysis used was the Family Biotic Index (FBI) supported by physical-chemical parameters. The results of this study showed that the macroinvertebrates identified were 721 individuals consisting of 5 classes, 17 orders, and 36 families. The water quality of the Jangkok River, based on the FBI value in the upstream and middle sections, is still included in the good category, while in the downstream section, it falls into the very bad category.

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.
