Abstract

Sea cucumbers are marine animals of the holothuroidea class (phylum Echinoderms), which are natural decomposers and play an important role in maintaining aquatic ecosystems. Sea cucumbers can clean up the remnants of organic matter on the seafloor, so that they can maintain the balance of nutrients in an ecosystem. This study aims to determine the species composition and structure of sea cucumber communities, including: abundance, diversity index, uniformity index, and dominance index, as well as to determine the influence of environmental parameters on the abundance of sea cucumber species. Sea cucumber data collection was carried out using the transect belt method, with a transect length of 100 m and a width of 1 meter to the left and 1 meter to the right, respectively, so that a total monitoring area of 200 m2 was obtained. At station 1, the width of the beach is less than 100 meters, so the area of the observation area is adjusted to these conditions. 6 species of sea cucumbers were found, namely: Synapta maculata, Opheodesoma grisea, Chirota smirnovi, Holothuria leucospilota, Actinopyga alboniger, Holothuria scabra. The total abundance value of sea cucumbers found in the waters of Elak-Elak Beach ranges from 164-172 ind/ha. S. maculata is the species with the largest abundance value, ranging from 500-883 ind/ha, while the species with the smallest abundance value are A. alboniger and H. scabra, at 17 ind/ha. Environmental parameters affect the abundance of sea cucumbers, where more sea cucumbers are found in habitats with muddy sand substrates and seagrass vegetation.

Abstract

Carbon dioxide is one of the greenhouse gases that reflects sunlight radiation. Mangrove trees have the ability to absorb and store carbon in the air, so the existence of a mangrove tree could be one of the solutions to the global warming problem. This research aims to find out the amount of carbon reserves in the mangrove communities that exist in Keranji Hamlet, Paremas, East Lombok. The survey method used in this research is an explorative descriptive method that will make it easier to understand and interpret the data. To determine the stock of mangrove carbon, data is needed that will influence the carbon content such as diameter, density, type and percentage of the coverage of the mangrove. In this study, six species of mangroves were identified: Avicennia alba, A. marina, Rhizophora apiculata, R. mucronata, R. stylosa, and Sonneratia alba. The average density value obtained is 988,889 ind/ha so it is known that the mangrove forests of Keranji Hamlet, Paremas, Jerowaru, East Lombok have rare cover conditions based on standard quality of forest damage. The average diameter of the mangrove tree is the highest value at transec 2, so the highest carbon reserve value is found at transec 2, whether it's root or rod. The average estimated reserve is spread out at 104.96 tons/ha of rod carbon and at 56.05 tons/he of root carbon that marks the rod carbon belonging to the high category and the rod carb belongs to the medium category.

Abstract

Global warming occurs as a result of greenhouse gas emissions and has become one of the world's biggest environmental problems today. Mangrove ecosystems play an important role in mitigating global warming through their ability to absorb and store carbon in their biomass. This study aims to determine the vegetation composition, biomass, and estimated carbon stock in mangrove biomass in the Poton Bako Hamlet mangrove area, Jerowaru District, East Lombok. The method used is a non-destructive method by measuring trunk diameter (DBH) using an allometric model approach to calculate above-ground and below-ground biomass, which is then converted into carbon stock. Four mangrove species were found at the research location: Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, and Sonneratia alba. The mangrove density in Poton Bako Hamlet is 2,611.11 individuals/ha, categorized as dense. Sonneratia alba is the mangrove species with the highest biomass content among the other species, with above-ground biomass values of 61.37 tons/ha and below-ground biomass of 33.04 tons/ha, with a total carbon stock value of 43.43 tonsC/ha. The total above-ground biomass value of the Poton Bako mangroves is 110.22 individuals/ha, and the below-ground biomass is 52.16 tons/ha. With this biomass value, the Poton Bako mangrove area is estimated to have a total carbon stock of 74.69 tonsC/ha, consisting of 50.70 tonsC/ha above-ground carbon stock and 23.99 tonsC/ha below-ground carbon stock.

Abstract

Gelombang laut merupakan elemen penting dalam oseanografi yang memengaruhi berbagai aktivitas di wilayah pesisir, seperti transportasi laut, pembangunan infrastruktur, hingga perikanan. Namun, ketersediaan data gelombang di Indonesia masih sangat terbatas dan umumnya hanya mencakup wilayah tertentu atau data lampau. Oleh karena itu, diperlukan pendekatan pemodelan seperti hindcasting gelombang agar informasi gelombang laut di Indonesia bisa diperoleh secara lebih luas dan akurat. Penelitian ini bertujuan untuk menganalisis karakteristik gelombang laut di perairan Indonesia dengan menggunakan model numerik Simulating WAves Nearshore (SWAN) melalui pendekatan nested model. Pemodelan dilakukan pada dua skala domain, yakni regional dan nested, dengan resolusi spasial masing-masing 0,25° dan 0,1°, serta periode simulasi dari tahun 2020 hingga 2023. Data input meliputi kecepatan angin dari ECMWF dan data batimetri dari GEBCO, yang kemudian divalidasi menggunakan data buoy di wilayah Australia. Hasil validasi menunjukkan bahwa model SWAN mampu menggambarkan tinggi gelombang signifikan (Hs) dengan baik, dengan nilai korelasi 0,699–0,921 dan RMSE yang relatif rendah. Analisis spasial dan musiman menunjukkan bahwa gelombang tertinggi terjadi pada musim timur (Juni–Agustus), terutama di wilayah selatan Indonesia, sedangkan gelombang terendah terjadi pada musim peralihan I (Maret–Mei). Hasil juga menunjukkan bahwa fenomena iklim global ENSO berpengaruh signifikan terhadap anomali Hs di wilayah utara Indonesia selama fase El Niño. Sementara itu, korelasi antara IODM dan anomali Hs menunjukkan pola negatif di wilayah selatan dan positif di wilayah utara.

Abstract

Mangroves are coastal ecosystems rich in biodiversity and play a crucial role both globally as carbon sinks and locally in maintaining ecological balance and providing habitats for various species. Understanding the structure of mangrove communities is essential, as it involves studying the components and interactions within the environment. This research aims to examine the community structure and canopy cover percentage of mangroves at Keranji Beach, Paremas Village, East Lombok. Mangrove data were collected using the line transect method, while canopy cover data were obtained using hemispherical photography. The study identified 7 mangrove species i.e: Sonneratia alba, Avicennia alba, Avicennia marina, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, and Bruguiera gymnorrhiza. The density of the mangrove ecosystem at the tree and sapling levels falls within the very dense category (≥1500 individuals/ha). S. alba was the species with the highest importance value index (INP) (231% - 271%), indicating its significant role and contribution to the mangrove community. For the seedling category, two mangrove species were found, R. apiculata and B. gymnorrhiza, each with a 1% presence. The average percentage of mangrove canopy cover was 64.8%, classified as moderate with a good rating.
