Abstract

Terumbu karang memiliki peranan krusial baik secara ekologi maupun ekonomi. Akan tetapi, kelestarian terumbu karang tercancam oleh berbagai faktor alamiah dan antropogenik baik dari darat maupun laut sehingga perlu dilakukan upaya rehabilitasi; salah satunya di pesisir Desa Pagerungan Besar, Kecamatan Sapeken, Kabupaten Sumenep. Pada kawasan tersebut, tutupan terumbu karang di sisi barat dan selatan pulau diketahui sebesar 19,05-26,05% atau termasuk dalam kategori ‘rusak’ hingga ‘sedang’. Salah satu upaya rehabilitasi adalah melalui transplantasi karang dengan media frame baja bersalut pasir (sand-coated steel frame) yang bersifat kokoh dan relatif tahan korosi. Kegiatan telah dilaksanakan pada Mei 2020 hingga November 2022, mencakup studi pendahuluan, sosialisasi dan workshop, pembuatan frame dan transplantasi karang hingga pemantauan secara kontinu. Setelah 2 tahun, nilai kesintasan karang transplan termasuk tinggi (>95%) dan pada permukaan frame juga telah tumbuh koloni karang keras (Scleractinia) hasil dari proses rekruitmen secara alami. Dapat disimpulkan bahwa transplantasi karang dengan media frame baja bersalut pasir dapat memenuhi fungsinya untuk memperbaiki sekaligus meningkatkan fungsi habitat terumbu karang rusak dengan luasan 90 m2. Selain itu, masyarakat lokal memiliki persepsi yang baik terkait pelaksanaan program dan mengharapkan adanya keberlanjutan dari program yang telah terlaksana.

Abstract

Indonesia is recognized as one of the world’s most biodiverse countries, with an estimated 17% of global plant and animal species found within its borders. This biodiversity supports a wealth of medicinal plants that have been traditionally utilized by local communities. However, rapid modernization has led to a decline in the transmission of ethnobotanical knowledge. This study investigates the ethnopharmacological practices in Sumberbrantas Village, Bumiaji District, Batu City, East Java, with a focus on the Family Use Value (FUV) approach to identify the most utilized plant families in traditional medicine. Data were collected through structured interviews with 70 respondents selected using purposive and snowball sampling techniques. The study analyzed the FUV and Fidelity Level (FL) of various plant species to determine their significance in traditional healing practices. Results indicate that the Zingiberaceae and Euphorbiaceae families have the highest FUV (0.45), highlighting their widespread use in treating various ailments. Conversely, the Oxalidaceae family exhibits the lowest FUV (0.01). The FL analysis shows that Allium cepa (shallot) has the highest fidelity level (75%), demonstrating its prominence in treating multiple conditions. This research provides critical insights into the preservation of ethnomedicinal knowledge and the sustainable use of medicinal plant resources. The findings serve as a valuable reference for conservation efforts and the development of community-based herbal medicine initiatives.

Abstract

Coral reefs are marine biota that have a fairly high level of sensitivity to changes in water conditions, both in terms of physical and chemical aspects. Damage experienced by coral reef ecosystems is increasingly occurring, this can be caused by human and natural activities. This research aims to determine the condition of the coral reef ecosystem on Saobi Island and Sapapan Island. The method used in this research is Underwater Photo Transect (UPT). The observation location consists of 7 stations, of which 4 stations are on Saobi Island and 3 stations are on Sapapan Island. The growth forms found are Acropora Branching (ACB), Acropora Digitate (ACD), Acropora Submassive (ACS), Acropora Tabulate (ACT), Coral Branching (CB), Coral Encrusting (CE), Coral Foliose (CF), Coral Massive (CM), Coral Mushroom (CMR), Coral Submassive (CS). The condition of the coral on Sapapan Island is included in the good category at station 1 with a live coral cover percentage of 53.67% and in the very good category at station 2 and station 3 with a live coral cover percentage of 78.87% and 77.80%. Meanwhile, on Saobi Island, the condition of coral reefs at station 1 is included in the medium category with a percent cover value of 46.53% and station 2 is 67.53%, station 3 is 65.33% and station 4 is 52.47% which is included in good category.

Abstract

Microplastics (MPs) are global concern due to their presence in various ecosystems and their tendency to have a negative impact on organisms. MPs are plastic fragments with a small size ranging from >1 μm to <5 mm, which are easily ingested by marine organisms, including marine sponges. As filter-feeding organisms, sponges can accumulate MPs in their bodies. This study aims to analyze the physical and chemical characteristics and the abundance of MPs in seawater and sponges. Three species of marine sponges (Xestospongia testudinaria/XT, Aaptos suberitoides/AS, and Clathria sp./CR) with ten replicate samples were collected from Batu Lawang reef in Pasir Putih, Situbondo, East Java, Indonesia. MPs samples were also collected from the water column (surface and sea bottom at a depth of ±6-7 m). Analysis of physical characteristics (shape, color, and size) performed using a stereo microscope and Optilab, whilst chemical characteristics (type of polymer) was analyzed using ATR-FTIR. A one-way ANOVA test followed by Tukey's HSD (both at p = 0.05) were performed to determine the difference in MPs density from each species. There was no significant difference in term of density in XT and AS, with average density of 60.6 and 66.9 particles/g wet weight (ww), respectively. The density in CR was significantly higher, with the value of 86.7 particles/g (ww). In the water column, the density was 20-27 particles/L (surface sample) and 37-84 particles/L (sea bottom). All particles dominated by black fragments with sizes ranging from 0 to 60 μm, and the polymer type is polypropylene (PP).
