Abstract

Sharks have an important role in balancing the ecosystem, but fishing activities that are not yet suitable for catching sharks can cause shark extinction. Therefore, it is necessary to identify the type and size of sharks caught by fishermen. The Tanjung Luar Fishing Port is the largest shark landing site in West Nusa Tenggara Province, making it an ideal research location regarding shark landings. This research analyzes species diversity, conservation status, length distribution, and sex ratio of landed sharks. Data collection in this research was carried out in November 2023 and February-March 2024. Primary data was collected by taking direct measurements of shark length and interviews with fishermen, while secondary data in this research was collected from FIP2B for West Nusa Tenggara Province. This research used species diversity and conservation status analysis, length distribution analysis, and sex ratio analysis. The research results show that shark diversity in 2022 is in the medium category, and in November 2023 and February-March 2024 is in the high diversity category. The lengths of the 3 sharks that dominate, namely Carcharhinus falciformis, Galeocerdo cuvier, and Sphyrna lewini, are almost all below the length of maturity (Lm). For the sex ratio, the sex ratio in 2022 is in a balanced condition, whereas November 2023 and February-March 2024 will be dominated by female sharks. Keywords: Carcharhinus falciformis, length frequency, sex ratio

Abstract

Saleh Bay is a water area located in West Nusa Tenggara (NTB) Province, which has experienced significant coral reef ecosystem degradation due to destructive fishing practices using fish bombs. The use of fish bombs has caused severe damage to marine habitats, including a decline in biodiversity and coral reef degradation. This study aims to identify the destructive fishing activities using fish bombs in Saleh Bay and analyze alternative mitigation strategies. Data were collected through interviews, discussions, and field observations in Prajak Subvillage, Batu Bangka Village, Sumbawa Regency. The analysis methods employed were descriptive analysis and SWOT analysis. The results showed that fish bombing activities are still ongoing with 12 active perpetrators. Law enforcement measures, such as the Smart Patrol and penalties for offenders since 2019, have not fully addressed the issue. A total of 70 fish bombing sites were identified around Dangar Island, Liang Island, Lipan Island, and Rakit Island. The proposed alternative strategies in this study include strengthening community-based patrols through local monitoring groups (Pokmaswas), external collaboration for funding, livelihood training for the community, providing incentives for offenders who switch to environmentally friendly fishing methods, and increasing socialization and education regarding applicable regulations. Key words: Fish bombing, law enforcement, patrol, Prajak Subvillage, Saleh Bay

Abstract

Economic valuation is an important instrument in making policies for managing coral reef resources effectively and efficiently and is able to distribute the value of benefits and costs in developing conservation areas. This study aims to determine the economic valuation of coral reef resources in TWP Gita Nada Sekotong Lombok Barat Regency. The research used the survey method with a sample size of 45 respondents determined by purposive random sampling based on the status of the respondent. Data analysis uses the Total Economic Value (TEV) approach by aggregating the value of direct benefits, indirect benefit values, value of selected benefits, value of existence benefits, and value of inheritance benefits. The results showed that the TEV of coral reef in TWP Gita Nada was Rp. 147,976,915,107.98/year or IDR 54,778,806.30/ha/year. The value of indirect benefits contributed IDR 113,523,601,904.00 per year (76.7% of the total economic value of coral reefs), while the direct benefit contributes Rp. 34,453,313,203.98 per year (23.3% of the total economic value of coral reefs).

Abstract

Cempi Bay is an important water area with a rich and diverse ecosystem. One crucial component of marine ecosystem that plays a major role in maintaining the balance of the marine environment is seagrass. The objective of this research is to provide critical insights into the dynamics of seagrass populations in Cempi Bay and offer an overview of the broader coastal ecosystem's condition. The research, conducted in June-July 2021 at 5 research stations, employed the transect method. At each data collection point, three transect lines were created perpendicular to the coastline. The distance between transect lines was 100 m, and each transect consisted of 10 quadrants measuring 1x1 m with a 5 m distance for each quadrant. Four seagrass species were identified: Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Cymodocea serrulata. These species were found on sand substrates, with the highest total density and percentage cover observed at Station 5 (1135.22 ind/m2 and 40.74%). The results highlight the necessity for routine monitoring, mapping, and further research to comprehend seagrass population dynamics and support effective conservation policies. Implementation of recovery strategies, water quality management, and continued research support is imperative to ensure the sustainability of seagrass ecosystems and marine resources in Cempi Bay.

Abstract

Sampah plastik merupakan permasalahan serius karena sifatnya yang sangat sulit terurai secara alami. Bentuk derifat dari sampah plastik yaitu sampah mikroplastik yang berukuran ≤ 5 mm. Berbagai penelitian menunjukkan terdapat sejumlah konsentrasi plastik dalam tubuh organisme perairan, seperti: plankton, kekerangan, krustasea, dan ikan. Kandungan plastik pada hewan tersebut dapat dipindahkan ke hewan pemangsanya termasuk manusia dalam rantai makanan. Konsentrasi plastik pada tubuh manusia dapat memicu pertumbuhan sel kanker yang mengancam kesehatan dan kelangsungan hidup manusia. Masyarakat Teluk Bumbang sejatinya telah mengetahui dampak negatif sampah plastik yang dibuang ke laut, namun dalam prakteknya masih banyak dijumpai karena hal tersebut sudah menjadi kebiasaan yang membudaya. Pengabdian kepada masyarakat ini berupaya menambah kesadaran masyarakat mengenai ancaman sampah mikroplastik terhadap lingkungan dan biota perairan, serta mengenai solusi pengelolaan sampah plastik. Kegiatan pengabdian kepada masyarakat ini menggunakan beberapa pendekatan, yaitu: (1) survei tentang pemahaman dan perilaku masyarakat terhadap sampah plastik; (2) penyuluhan mengenai ancaman sampah plastik; (3) pelatihan pembuatan ekobrik untuk mengurangi laju produksi sampah plastik. Kegiatan pengabdian kepada masyarakat ini dihadiri kelompok nelayan Teluk Bumbang dan Kelompok Sadar Wisata (Pokdarwis) Desa Mertak, Kecamatan Pujut, Kabupaten Lombok Tengah. Hasil survei menunjukkan bahwa sebagaian besar masyarakat masih membuang sampah di sembarang tempat sedangkan yang lainnya membuang sampah ke TPS (Tempat Pembuangan Sementara). Setelah mendapatkan penyuluhan mengenai ancaman sampah plastik, masyarakat menunjukkan komitmennya untuk berhenti membuang sampah sembarangan dan berkomiten dalam upaya mengelola sampah plastik menjadi produk yang bernilai ekonomis, misalnya ekobrik

Abstract

The fish processing and marketing group (poklahsar) in the Gili Matra Marine Protected Area has received intervention from the central government through Bappenas in the COREMAP-CTI III program. This intervention involves improving human resource capacity and providing grants for fish processing equipment. However, the limited duration of the program has resulted in suboptimal assistance in utilizing the donated fish processing equipment. Therefore, the involvement of universities in assisting the community is deemed necessary. This assistance activity aims to inform and educate the poklahsar about the use of fish processing equipment, particularly machines, to enhance production capacity in the Gili Matra Marine Protected Area. The assistance activities were carried out in July 2023 at the respective production locations of each poklahsar. The educational method for adults in this assistance activity involves lectures and hands-on practical training. The outcome of this assistance activity is an increased understanding and knowledge among poklahsar in the Gili Matra Marine Protected Area regarding the functions and uses of various machine-based fish processing equipment. Additionally, it was identified that some obstacles hinder optimizing machine-based equipment utilization, including a lack of understanding in using such equipment and limited market demand for processed fish products. In conclusion, the poklahsar have diverse views on using machine-based equipment, enabling them to optimize the use of such equipment despite the limited demand for processed fish products.

Abstract

Baronang fish is a type of fish that is commonly found in the waters of the Alas Strait. Baronang fishing carried out continuously can affect the growth and existence of baronang fish in waters. This study aims to find out the types of baronang fish, the composition of types and sizes of baronang fish, as well as to find out the growth pattern of baronang fish caught in the waters of the Alas Strait. This research was conducted from April to June 2025. Data collection was carried out through interviews who were selected using the Snowball sampling method and direct measurements. Fish length measurement was carried out with the WCS Image Tools application, and the data obtained was analyzed through identification, length distribution analysis, type composition, and the relationship between length and weight of baronang fish. The results of the study show that there are 7 species of baronang fish in the waters of the Alas Strait. The species Siganus canaliculatus is the most common species found in the waters of the Alas Strait, with a percentage of 53.15%. On the other hand, the species with the lowest number of individuals are Siganus corallinus and Siganus spinus, which is equivalent to a percentage of 0.23%. The growth pattern of baronang fish in the waters of the Alas Strait showed a negative allometric growth pattern (b<3) which indicates that the increase in the body length of the fish is faster than the increase in weight. Key words: Alas Strait, growth pattern, rabbitfish
