Abstract

Gili Sulat and Gili Lawang have the potential to become a source of livelihood for the community due to their high biodiversity, where these two small islands can be used as a place for fisheries and ecotourism development. However, in West Nusa Tenggara itself there is still widespread destructive fishing which can affect the abundance of reef fish. Therefore, this research focuses on assessing the diversity and abundance of reef fish in the waters of Gili Sulat and Gili Lawang, Sambelia District, East Lombok Regency. This research was conducted from November 2023 to February 2024. Reef fish abundance data was collected using the UVC (Underwater Visual Census) method. The research results showed that there were 76 species, 38 genera and 16 families of reef fish in total at the six observation stations. The largest number of reef fish individuals is in the Pomacentridae family with 1180 individuals (0.79 ind/m2). The highest biomass of herbivorous fish and target fish is found in the Gili Sulat Sustainable Fisheries Zone, namely 2312.72 gr/m2, followed by the Gili Lawang Core Zone with a biomass value of 1221.32 gr/m2, while the Gili Lawang Utilization Zone has the lowest biomass value among all observation station.

Abstract

Intertidal biota consist of various invertebrate organisms that inhabit coastal aquatic environments and are highly responsive to fluctuations in water quality. Environmental changes induced by shrimp pond waste discharge can substantially influence the composition and diversity of intertidal biota communities. As a result, water quality serves as a critical determinant in maintaining the ecological balance and sustainability of coastal ecosystems. This study aims to analyze gastropod diversity within the intertidal zone near a shrimp pond waste discharge site and assess water quality based on the diversity index in Labuan Pandan, Sambelia Village, East Lombok. The research was conducted between June and November 2023, with data collected from five sampling stations located directly in front of the discharge site. A total of 40 gastropod species, classified into 32 genera and 22 families, were identified. The highest Diversity Index (H') was recorded at station 5 (2.503), whereas the lowest value was observed at station 2 (1.569). The highest Uniformity Index (e) was found at station 4 (0.947), while the lowest was at station 3 (0.811). The Dominance Index (D) was highest at station 2 (0.245) and lowest at station 5 (0.112). Sediment analysis across all stations revealed two predominant substrate types: loamy sand and sandy loam.

Abstract

Hard corals (Scleractinia) serve as essential reef constructors and offer habitats for numerus marine species. This study aimed to asses the diversity of hard coral (Scleractinia), genera dan percentage of live coral cover in Nipah Bay as fundamental data for sustainable reef management. The research was conducted in July 2025 at three observation stations with two depth levels (3 and 7 meters). Data collection utilized the Underwater Photo Transect (UPT) method, while coral identification employed Coral Finder 2.0 and CPCe (Coral Point Count with Excel extension) software. Result indicated that live hard coral cover ranged between 10.47 % and 46,73%, which according to the ministry of environment Decree No. 4 2001, falls within the demaged to moderate category. A total of 28 genera and 1,859 hard coral colonies were documented, with Porites, Favites, Montipora, and Pocillopora identified as the dominant genera. The diversity index (H’) ranged form 1.67-2.01, mean 1,86; moderate, the evenness index (E) rangged from 0,60-0,78, mean 0,70; high, and the dominance index (D) ranged from 0,17-0,29, mean 0,22; low. These outcomes suggest that the hard coral community in Nipah Bay remains relatively stale and balanced, though shallow regions exhibit degradations likely due antrophogenic pressures and environmental stress. Sustained monitoring and cominity based conservation are recommended to support coral reef resilience and ecosystem health.

Abstract

Mangroves play a crucial role in maintaining environmental balance, including wave attenuation, preventing erosion, providing habitat for various species, and storing carbon to mitigate climate change. However, mangrove ecosystems are currently facing serious degradation threats due to human activities and climate change, necessitating protective measures, rehabilitation, and active community participation to ensure their preservation. This community service initiative aims to conserve mangrove ecosystems through nursery activities (nursery) and mangrove planting (out-planting) in potential areas not yet populated by mangroves in Siung Village, Sekotong, West Lombok. The nursery activities include techniques for collecting seedlings from the wild, selecting and sorting healthy seedlings, placing them in planting media, and caring for the seedlings. Meanwhile, the out-planting activities involve planting the seedlings in the wild and monitoring the planted mangroves to ensure their survival. Over approximately two months, this project has produced 3,200 mangrove seedlings of Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa, and Ceriops tagal species, with a survival rate of 87.5%. As for the out-planting activities, 2,700 mangrove seedlings have been successfully planted in areas near the nursery site. Challenges encountered during seedling collection and care include tidal fluctuations, the presence of pests and predators. In the out-planting activities, ongoing monitoring and maintenance are required to maintain a high survival rate for the seedlings planted in the wild.

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

Cultivation of pearl oyster Pinctada maxima types are increasingly in demand in Indonesia. This oyster living and concentrated on waters that have coral reefs and sandy rubble. Oyster cultivation is very promising given pearls produced have a high economic value. Eventhough, pearl oyster farming efforts not always performing well because there is a possibility of oysters will get the disease and even death. One reason is their biofouling attached to the basket or on the oyster shell is maintained. The existence and amount of biofouling usually varies depending on the time and conditions of the waters where the cultivation have been. This study aims to determine the types of biofouling were found at three different sites located on land cultivation PT. Pearl Culture Autrore Lombok. Study sample is limited to biofouling found on new and used baskets and pearl oyster shells P. maxima. The main parameters measured were the species composition and abundance, while the supporters of the parameters measured were temperature, salinity, current speed, the brightness of the waters and TSS (Total Suspended Solid). The results found 36 types of biofouling, including 21 types of animal groups with six phyla (arthropods, bryozoans, annelids, cnidarians, sponges and molluscs), and 15 species of the plant with two divisio (Spermatophyta and Thallophyta). In addition, it was found that water conditions have an influence on the biomass and the number of types of biofouling and the distance between substations in each station does not have a significant influence on biomass and the number of types of biofouling.Keywords: Biofouling, Pearl Oyster (Pinctada maxima ), PT.

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.
