Abstract

Development and operational activities in KEK Mandalika can increase sedimentation of waters caused by erosion of construction material activities, this have an impact on coral reef ecosystems. Coral reef ecosystems have several important roles in support life of various aquatic organisms, Damage to the coral reef ecosystem directly and indirectly, sooner or later will threaten the sustainability of the use of these resources (social economy) and the safety of the community. Observations were conducted in KEK Mandalika coastal at 6 observation points less than 10 m. The results showed that the highest percentage of live coral cover was found in Kuta Mandalika coastal at PIT 4 area (30%, damaged category, moderate status). While the lowest percentage of coverage was at PIT 5, which was 2% (damaged category, bad status). Overall the percentage of coral cover in the Kuta Mandalika area is included in the damaged category. One of the reasons is because at the lowest tide on the beach, the volume of water is very small so that many hard corals are exposed to solar radiation. This limits the types of hard corals that can grow in the intertidal zone of Mandalika coastal. Genus diversity at this location is low, ranging from 0.0782 to 0.1288. Several genera of the Nephtheidae family dominate the observation sites and form colonies of the same genus with a fairly large distribution. The average value of environmental parameter measurements in the Mandalika coastal is included in the good category for soft coral habitat and growth.

Abstract

This study aims to examine the structure of sea urchin (Echinoidea) communities in the tidal zone of Kuta Mandalika Bay. The research was conducted in August 2024 at three different stations: River Estuary (Station 1), KEK Tourism Area (Station 2), and Mangrove Ecosystem (Station 3). Data collection was carried out using purposive sampling with line transects and plots to identify species, abundance, and environmental parameters (substrate and salinity). The results identified four sea urchin species: Diadema setosum, Tripneustes gratilla, and Enchinometra mathei. Station 2 exhibited the highest diversity and abundance (H' = 2,31; 68.70% abundance), characterized by a rocky sand substrate and salinity of 30 ppt. In contrast, no sea urchins were found at Station 1, which had a muddy sand substrate and lower salinity (28 ppt). Station 3 showed moderate diversity (H' = 1.77) with 50% abundance. Environmental factors such as substrate type, salinity, and the presence of mangrove vegetation significantly influenced the distribution of sea urchins. This study highlights the critical role of habitat characteristics in shaping sea urchin community structure in the tidal zone.

Abstract

The mangrove forest in Cendi Manik Village, West Lombok Regency, consists of both natural and rehabilitated areas, the latter of which has been developed into the Bagek Kembar Mangrove Ecotourism site. While the growth of ecotourism has increased public and governmental attention toward the rehabilitated zone, concern for the natural mangrove forest has declined. This study aims to identify mangrove species composition and analyze vegetation density and diversity in the Cendi Manik mangrove area. The research was conducted from February to March 2024 using vegetation analysis methods across 15 plots distributed along three transects. The results identified six main mangrove species: Avicennia marina, A. alba, Rhizophora apiculata, R. mucronata, R. stylosa, and Sonneratia alba, with Rhizophora mucronata being the most dominant species, having the highest tree density of 440 individuals/ha. The total tree density reached 1,373.34 individuals/ha, which is categorized as dense according to Indonesian Ministry of Environment Regulation No. 201/2004. The species diversity index (H’) ranged from 1.54 to 1.61, indicating moderate to high diversity levels. The dominance of muddy substrates in the area supports the optimal growth of Rhizophora species. These findings highlight the ecological importance of conserving the remaining natural mangrove forests in Cendi Manik Village, given their vital role in coastal protection, carbon storage, and habitat provision for coastal biota. This research serves as a foundation for more comprehensive and sustainable conservation strategies in the region.

Abstract

Climate change is a condition of climate elements whose intensity tends to change or deviate from average dynamics and conditions. Climate change is mainly caused by anthropogenic activities which produce greenhouse gas (GHG) emissions. This condition has an impact on the agricultural sector. This research aims to determine the impact of climate change on the agricultural sector by analyzing data obtained from the West Lombok Regency government and also comparing data from BPS with direct interviews with the farming community of Tempos Village to determine the effect of climate change on agricultural production in Tempos Village. The method used in this research is descriptive qualitative. The research results show that climate change in the context of temperature and rainfall parameters affects the agricultural sector in terms of plant growth and crop yields or agricultural production.

Abstract

West Nusa Tenggara has a high level of fauna (animal) characteristics, because its position is on the Wallacea line as an ecological transition between the continents of Asia and Australia. The fauna in NTB varies according to the existing ecosystem, this happens because there is a match between the species and the environment or place where they develop. An ecosystem that experiences changes in certain conditions can also cause changes in species variations. Climate change is one of the causes of changes in an ecosystem. This research aims to determine the impact of climate change on biodiversity conditions in NTB. Research activities were carried out at the offices of the NTB Environment and Forestry Service, the NTB Natural Resources Conservation Center, and the NTB Maritime and Fisheries Service, for interviews and requests for data regarding climate change and diversity in NTB. The research method used was purposive sampling. The results of animal data show that this species already has a small number in NTB so it must be immediately conserved by the local government so that it does not experience extinction due to climate change.

Abstract

The global climate changes that are currently occurring can have a significant impact on the plantation and forestry sectors in Sesaot Village, West Lombok Regency. Even though the plantation technology used by the people of Sesaot Village is still traditional, there are also very diverse types of plantation crops in the village which can make a significant contribution to the local economy, the main challenge faced is increasing temperatures which have the potential to reduce harvest yields and forest productivity. Due to changes in temperature experienced by the community from year to year, it shows a significant increasing trend. Based on data from the West Lombok Regency Meteorology, Climatology and Geophysics Agency (BMKG), the period from 1997 to 2024 in May shows a trend of increasing temperatures that continues from year to year. This research aims to analyze the concrete impact of global climate change and adaptation on the plantation and forestry sectors in Sesaot Village. In facing this challenge, cooperation between government, society and other related parties is very important. Efforts to increase awareness of the impacts of climate change and encourage the adoption of modern technology in the plantation sector can be key steps in mitigating possible negative impacts.

Abstract

This research analyzes the impact of climate change on the vulnerability of coastal areas and small islands in Gili Air, North Lombok. Climate change, including rising temperatures and sea levels, is affecting coastal ecosystems, such as coral reefs which are vulnerable to bleaching and death. This study identifies a trend of increasing built-up land on Gili Air in the 2013-2022 period, which is caused by tourism promotion policies. The impact of this policy causes an increase in the number of tourists and local residents, which then increases the need for tourism supporting facilities. These land cover changes and development pressures increase Gili Air's environmental and economic vulnerability to climate change. These findings emphasize the importance of comprehensive adaptation and mitigation strategies to preserve the sustainability of ecosystems and the livelihoods of local residents.
