“…Zona Intertidal memiliki variasi faktor lingkungan yang luas dibandingkan dengan daerah lautan lainnya, hal ini tersebut menyebabkan keanekaragaman jenis yang tinggi. Keanekaragaman jenis dapat digunakan untuk menyatakan struktur dan stabilitas komunitas (Bramasta, 2014). Zona Intertidal adalah area sempit dalam sistem bahari antara pasang tertinggi dan surut terendah.…”

“…Dari data di atas dapat disimpulkan bahwa, jenis bivalvia di Pantai Ntana tergolong tinggi, dapat dilihat pada penelitian Bramasta (2014), yang berjudul "Keanekaragaman Jenis Bivalvia di Zona Intertidal Pantai Pancur Taman Nasional Alas Purwo", hanya 3 jenis Bivalvia yang ditemukan di sepanjang pantai Pancur Taman Nasional Alas Purwo. Kemudian pada penelitian Yuliansari (2020), yang berjudul "Kandungan Logam Berat Timbal (PB) pada Beragam Jenis Bivalvia di Kawasan Pantai Kabupaten Bangkalan", pada penelitian ini ditemukan jenis Bivalvia yang berbeda di kawasan pantai Kabupaten Bangkalan.…”

Bivalves belong to the Phylum mollusca. Bivalve are found and live in the Intertidal area. Ntana Beach is the easiest area and has the most interaction with human activities, because this area is a transitional area between aquatic ecosystems and land ecosystems. This study aims to: 1) identify the types of bivalves that make up the Intertidal zone on the Ntana coast, Bima Regency; 2) analyzing the abundance, diversity index, and evenness of Bivalvia in the Intertidal zone on the Ntana coast, Bima Regency; 3) describe the population of bivalve species that dominate the Intertidal zone on the Ntana coast, Bima Regency; 4) analyzing the abundance of bivalves in the sandy, muddy and rocky substrate areas on the Ntana beach, Bima Regency; 5) analyzing the diversity of bivalve species in the area of sandy substrate, muddy substrate, and coral substrate on the Ntana beach, Bima Regency; 6) knowing the differences in the dominance of Bivalvia in the sandy, muddy and rocky substrate areas on the Ntana beach, Bima Regency; and 7) to develop research results on a comparative study of the quantity of bivalves in the intertidal zone on the Ntana coast, Bima district as an effort to prepare a conservation brochure. This type of research is descriptive comparative. Sampling used a 1x1 M plot. The results showed that as many as 540 individual bivalves consisting of 15 species were found on the Ntana beach, Bima district. 15 species of bivalves found include Anadara antiquata, Anadara granosa, Anadara brasilliana, Panopea generosa, Fausta pultenei, Dosina crebra, Eurytellina alternate, Dosina discus, Nactula acuta, Gafrarium divaricatum, Dosinia exoleta, Caestoderma edule, Gafrarium disparm, Cyclocardia ventricosa, and Crassostrea gigas. The abundance on sandy and silty substrates is categorized as moderate, whereas on coral substrates it is categorized as low. Species diversity on rocky substrates is less, whereas on muddy and sandy substrates each has a fairly high level of species diversity. The evenness value on sandy and muddy substrates is close to zero (0), so that the evenness of Bivalvia species on both substrates is not evenly distributed. There are no species that dominate other species because D <0.5. The average value of the brochure validation test is 75.4%, with this result, the brochures that have been compiled are in the good category and do not need to be revised.

Rumput laut Padina australis merupakan jenis rumput laut yang ditemukan di Pantai Sendang Biru Malang. Padatnya aktivitas kelautan di pantai tersebut diduga dapat menimbulkan pencemaran perairan berupa pencemaran logam Cd. Rumput laut yang terpapar logam Cd akan berpengaruh terhadap kadar protein dan kadar klorofilnya sehingga dapat menghambat pertumbuhannya. Tujuan penelitian ini adalah menganalisis kadar logam kadmium, kadar klorofil, kadar karaginan pada rumput laut Padina australis serta menganalisis hubungan antara kadar logam kadmium terhadap kadar karaginan. Pengambilan rumput laut Padina australis dilakukan di Pantai Sendang Biru Malang pada tiga stasiun. Analisis kadar Cd dengan AAS dan kadar klorofil dengan spektrofotometer. Data dianalisis statistik korelasi Pearson untuk mengetahui hubungan kadar logam Cd dengan kadar karaginan pada Padina australis. Hasil penelitian menunjukkan kadar logam Cd Padina australis sebesar 0,019 - 0,027 mg/kg, dimana kisaran tersebut dibawah baku mutu, dengan begitu aman untuk dimakan, kadar klorofil total berkisar 19,958-20,025 mg/L, kadar karaginan (protein) berkisar 1,73-2,15%, serta hubungan kadar logam Cd dengan kadar karaginan Padina australis memiliki korelasi negatif, semakin tinggi kadar Cd, maka kadar karaginan semakin rendah.

“…Its distribution is in the intertidal area, the upper littoral zone to the sublittoral zone, usually in the coastal areas [2]. Live attached to rocks or other hard materials, and some are attached to the seabed using a holdfast [3] and can grow at 0.5-10 m depth [4]. The highest biomass of Sargassum sp in May and June was during the dry season with suitable water temperatures of 25-35°C and salinity of 32-33.5‰ [5,6].…”

Sargassum sp is a type of brown marine macroalgae with bioactive or phytochemical compounds that function as antibacterial. This study aims to detect and isolate bioactive compounds and determine antibacterial activity of flavonoid compounds (rutin and quercetin) and phenols (gallic acid) from Sargassum sp to control Vibrio parahemolyticus. The methods were optimizing extraction and fractionation methods of Sargassum sp extract, as well as testing efficacy of antibacterial activity of flavonoid and phenol compounds from Sargassum sp extract against V. parahaemolyticus bacteria by observing the inhibition zone around the paper disc. The experimental design used the ONE-WAY ANOVA test. The results showed that the yield of Sargassum sp extract could be obtained optimally by the multi-staged maceration method around 82.56%, 89.78%, and 87.78% with n-hexane, ethanol, and ethyl-acetate solvents, respectively. Fractionation of Sargassum sp extract, which was dissolved with ethylacetate and ethanol separately to produce isolates of flavonoids (rutin and quercetin), and phenol (gallic acid). Antibacterial activity of the rutin compound from Sargassum sp extract has the highest inhibition and can inhibit the growth of V. parahaemolyticus bacteria with an inhibition diameter of > 25 mm. Sargassum sp extract can be used to control bacteria disease V. parahaemolyticus in-vitro.
