Abstract

Protection and sustainable data collection are very important in order to protect the coral reef ecosystem. This research was conducted to monitor and determine the condition of coral reefs in the eastern part of Gili Gede Island, which is administratively located in Sekotong Sub-District, West Lombok Regency, NTB. The method used is Line Intercept Transect (LIT). Furthermore, the starting point of the transect stretch is recorded using GPS coordinates and the depth gauge is used to estimate the depth of the water. The results showed that the status of coral reefs tended to be badly damaged with the mean value of all stations (21.92%). Fishery activities and pressure from the land are thought to be several factors that tend to affect the poor coastal ecosystem

Abstract

Sea turtles are one of the key biota in coastal and marine ecosystems whose existence is not only ecologically important, but also holds social, cultural, and economic value. Indonesia, as the largest archipelagic country in the world, is home to six of the world’s seven sea turtle species, making it a globally significant habitat for the sea turtle life cycle. The Gili Matra Marine Protected Area, encompassing the three islands of Gili Trawangan, Gili Meno, and Gili Air, is one of the strategic regions with high potential for sea turtle conservation. This study aims to document and analyze the spatial distribution and habitat use of green turtles (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata) in the Gili Matra Marine Protected Area. Data collection was carried out during the period of September to October 2024, adjusted to weather conditions and water visibility. The method used was the Underwater Turtle Visual Census Methodology. The composition of sea turtle species and habitat characteristics were analyzed using descriptive analysis to summarize the patterns of species presence, habitat types, and environmental conditions observed during the survey. The findings indicate that the area supports both species, with sea turtles observed at various depths (9–16 meters) across multiple dive sites. The predominance of female individuals and the variation in species presence across sites suggest species specific habitat preferences and potential influences of environmental conditions. Both sea turtle was mostly observed in locations associated with coral reef structures.

Abstract

The whale shark (Rhincodon typus) is the largest fish species in the world that is not aggressive to humans, so it has become a popular tourist icon. The presence of whale sharks has become a tourist magnet and has transformed Botubarani Village from an ordinary fishing village into a bustling tourist village. However, the Covid19 pandemic has dealt a severe blow to whale shark tourism on the coast of Botubarani Village. The drastic reduction in tourists not only eliminates tourist income but also stops whale shark monitoring activities. The government's New Normal pilot is the hope for the return of whale shark tourism on the coast of Botubarani Village. Preparations for the opening of PPKM in the area of ​​origin of tourists and the ease of domestic/foreign travel will be greeted with an increase in the quality and innovation of whale shark tourism at Botubarani Beach. In addition, the adaptation of tourism during the pandemic by utilizing the internet is quite promising so that tourism will stay alive. The Innovation Village of Botubarani develops a live broadcast of an underwater virtual cruise with whale shark objects periodically in the wild. This development is the first in Indonesia because it has never been done before. The use of underwater closed circuit television (CCTV) that can be accessed on land and integrated with the internet allows whale sharks on Botubarani Beach to be enjoyed by anyone and anywhere. Villages and communities on Botubarani Beach can receive input from ongoing tourism developments from tourists who come or virtually. Tourists may also be interested in coming after watching a live broadcast of whale sharks on the beach of Botubarani Village. In addition, live video recording of whale sharks can also be utilized by intellectuals, government and industry as part of the triple helix collaboration.

Abstract

Pola kemunculan hiu paus di Probolinggo berbeda dengan lokasi lain di Indonesia, diduga kemunculannya memiliki hubungan dengan ketersediaan zooplankton. Tujuan penelitian ini adalah untuk mengkaji komposisi spasial dan temporal zooplankton serta mengaitkan dengan kemunculan hiu paus. Penelitian dimulai Bulan Desember 2017 - November 2018 dan terdapat enam titik pengamatan tiap bulannya. Air disaring menggunakan plankton net dan diawetkan menggunakan lugol. Pengamatan menggunakan mikroskop Olympus CX23 dengan dua kali ulangan. Hasil analisis spasial menunjukan adanya variasi terhadap keberadaan hiu paus di setiap stasiun (Chi-square test, X2= 1418.6, P <0.05) dengan kemunculan tertinggi diamati di stasiun PR_5 sebanyak enam individu. Namun, jumlah zooplankton tidak menunjukkan perbedaan yang signifikan di setiap stasiunnya. Berdasarkan analisis temporal, kemunculan hiu paus berbeda signifikan setiap bulannya (Chi-square test, X2= 81.04, P <0.05), dengan bulan Maret dan November menunjukan kemunculan tertinggi, tiga individu. Terdapat variasi kelimpahan dalam jumlah zooplankton (Chi-square test, X2= 148.61, P <0.05), dengan kelimpahan terbesar terjadi pada bulan April dan Maret. Baik secara spasial maupun temporal, korelasi kemunculan hiu paus terhadap komposisi zooplankton tidak berhubungan (r= 0.01, P< 0.05). Selain itu, korelasi antara hiu paus terhadap jenis zooplankton yang ditemukan juga dilakukan, hasilnya menunjukan bahwa Acartia sp. terindikasi menjadi jenis target hiu paus tersebut (r= 0.3, P <0.05), dimana kemunculan hiu paus tidak dipengaruhi oleh jumlah zooplankton yang tersedia, namun berdasarkan kebutuhan kalorinya.

Abstract

The coral reef ecosystem in Indonesia boasts the highest biodiversity and serves as the center of the Coral Triangle's diversity. Despite its richness, Indonesia's coral reefs face increasing threats from various factors, primarily anthropogenic. Regular biophysical surveys of coral reef ecosystems are therefore necessary to monitor their current conditions and guide management efforts. This study aimed to assess the condition of coral reefs by examining the percentage of coral cover in the Gili Balu Marine Conservation Area, Sumbawa NTB. The research was conducted in January, 2022, using the Point Intercept Transect (PIT) method at 10 observation points. The transects measured 50 meters in length and were repeated three times at each location. The results indicated that the coral reefs were in good condition at the South Belang Island Station (57%) and West Pasareang Island (69.67%), according to Kepmen LH No. 4/2001. However, moderately damaged reefs were observed at North Belang Station (38%), Kenawa Island (30%), East Belang Island (30%), and Mandiki Island (28.67%). Coral reefs classified as severely damaged were found at Southwest Namo Island Station (17.33%), North Pasareang (16.67%), South Kalong (11%), and North Namo (9.67%). Overall, the dominant condition of coral reefs in the Gili Balu Conservation Area was categorized as moderately to severely damaged. Conservation efforts, including protection in areas with good conditions and rehabilitation in damaged areas, are recommended as follow-up actions to support coral reef sustainability in Gili Balu.

Abstract

This study aims to assess the condition of coral reefs based on benthic composition in the shallow waters of Tanjung, Senggigi Beach, West Lombok, West Nusa Tenggara. Data collection was carried out through diving using the Underwater Photo Transect (UPT) method by analyzing 50 quadrat photos taken along a 50-meter transect line, processed with the CPCe software. The analysis revealed that live coral (Coral) was the most dominant benthic component, with an average cover of 91.38% ± 13.72%, which falls under the "very good" category. Macroalgae and abiotic components such as sand and coral rubble were present but in very small proportions. The coral community was dominated by complex growth forms such as Acropora tabular, Acropora branching, Coral foliose, and Coral massive, which are known for their relatively fast growth and adaptability to clear water with stable substrates. These findings indicate that the reef ecosystem in the waters of Tanjung Senggigi is in very good condition and provide a scientific foundation for developing effective management and conservation strategies for the area.

Abstract

The Gili Balu Marine Conservation Area (KKP), located in Sumbawa Regency, West Nusa Tenggara, is ecologically and economically significant due to its rich coral reef ecosystems. This research aims to measure the abundance and biomass of reef fish in the KKP Gili Balu, which can be used as a basis for evaluating the effectiveness of conservation efforts in maintaining marine biodiversity. The Underwater Visual Census (UVC) method was used, recording types of reef fish at ten observation points. The results showed that the highest abundance was found on Mandiki Island, with functional fish abundance reaching 2973 ind/ha, followed by Pasareang Barat Island (1903 ind/ha) and South Kalong (1600 ind/ha). The biomass of functional fish also reflects their important role in maintaining the balance of the coral reef ecosystem. This research contributes to the scientific understanding of marine biodiversity in the KKP Gili Balu and provides a basis for sustainable conservation management efforts. Additionally, the research recorded the presence of several coralivorous and economically important fish species, although they tend to be smaller compared to functional fish. Economically important fish in the KKP Gili Balu waters were found only at four observation locations: East Belang Island, North Belang, Kenawa, and Southwest Namo. The highest value was recorded at Kenawa Island, with 93 ind/ha. These fish tend to be rare in this area, possibly due to past fishing practices.

Abstract

Mangroves are vegetation that generally have woody stems and consist of shrubs whose life cycle is on the coast and can adapt to tidal seawater. This study aims to identify mangrove species, density conditions, frequency, damage criteria, and temporal changes in mangrove areas using Landsat 7 ETM and Landsat 8 OLI-TIERS imagery data in Teluk Jor. This research was conducted from June to July 2024 in Teluk Jor with a total of 9 observation plots. The methods used in this study include remote sensing methods and location point determination using purposive sampling methods. The data analysis used in this study includes vegetation density analysis and remote sensing analysis for mangrove mapping. The results showed that there were 6 types of mangroves found in Teluk Jor, namely Avicennia marina, Ceriops tagal, Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, and Sonnerati caseolaris. The highest density of mangrove species in Teluk Jor was Rhizophora apiculata with 3,034 ind/ha, and the lowest density of mangrove species was Ceriops tagal with 67 ind/ha, with the highest frequency being Rhizophora apiculata. The highest total mangrove vegetation density in the second transect was 3,833 ind/ha, and the lowest total mangrove vegetation density in the third transect was 1,967 ind/ha. The standard criteria for mangrove forest damage in Teluk Jor are in good condition with dense density, and there has been a decrease in the mangrove ecosystem area from 2003 to 2023 by 72.94 Ha.
