Abstract

Sargassum policystum is one of the genus Sargassum from the brown macroalgae group which has an abundance of chemical constituents of fucoidan, fucoxanthin, phenolic acids and alginate which have important biological activities, such as antioxidants and antibacterials. This species thrives in the waters of Kabung Island, Bengkayang, West Kalimantan and has not been exploited so that it tends to act as a marine weed. This study aimed to determine the total phenolic content of the ethanolic extract of S. policystum and its antioxidant and antibacterial activity. Determination of the total content of phenolic compounds using the Folin Ciocalteu method, antioxidant testing using the DPPH method (2,2-diphenyl-1-picrylhydrazyl) and the indicator of sample color change with the addition of these radicals was measured by UV-Vis spectrophotometer. Antibacterial testing was carried out by the test sample diffusion method and the inhibition of the growth of the test bacteria Staphylococcus aureus and Escherichia coli as test bacteria was indicated by the formation of a clear area around the sample wells. The results showed that the phenol content of the ethanolic extract of S. policystum was 79.8 mg/g extract, its antioxidant activity (IC50) was 98.903 ppm, classified as a strong antioxidant, while the comparison antioxidant, Vitamin C, had an IC50 of 6.26 ppm. The inhibitory ability of the ethanol extract against the test bacteria used was indicated by the formation of the largest inhibition diameter on S. aureus of 12.4 mm and E. coli of 12.0 mm.

Ekowisata Mangrove Telok Bediri terletak di Desa Sungai Kupah, Kecamatan Sungai Kakap, Kabupaten Kubu Raya, Provinsi Kalimantan Barat. Ekosistem mangrove ini menopang keberlanjutan berbagai jenis mangrove seperti Avicennia lanata, Avicennia marina, Nypa fruticans, Rhizophora apiculata, dan Sonneratia alba. Kabupaten Kubu Raya dikenal memiliki ekosistem mangrove yang kaya dan beragam, menjadikannya sumber penting untuk eksplorasi bahan alam dengan potensi pengembangan obat. Skrining fitokimia berfungsi sebagai langkah awal untuk menggambarkan golongan senyawa yang terkandung dalam tanaman yang sedang diteliti. Meskipun potensinya besar, hingga kini belum ada kajian mengenai kandungan metabolit sekunder pada mangrove dari kawasan ekowisata Telok Bediri, Kabupaten Kubu Raya. Sehingga penelitian ini bertujuan untuk mengidentifikasi senyawa metabolit sekunder pada ekstrak etanol daun A. marina, S. alba, dan N. fruticans melalui skrining fitokimia. Metode uji fitokimia yang digunakan pada penelitian ini adalah eksperimen laboratorium dan proses ekstraksi menggunakan metode maserasi menggunakan etanol teknis 96%. Hasil skrining fitokimia menunjukkan bahwa A. marina mengandung senyawa alkaloid dan saponin, tetapi tidak mengandung flavonoid, terpenoid, steroid, maupun tanin. Sebaliknya, S. alba dan N. fruticans tidak menunjukkan keberadaan senyawa alkaloid, flavonoid, saponin, terpenoid, steroid, maupun tanin. Temuan ini memberikan wawasan awal tentang kandungan kimia mangrove di kawasan ekowisata Telok Bediri dan mendukung potensi eksplorasi lebih lanjut untuk pengembangan bahan alami yang bernilai farmasi.

Abstract

Mangroves play a vital role in maintaining environmental, providing habitat for various organisms, and protecting coastal areas from abrasion. In addition, mangroves function as carbon sinks, where a portion of the captured carbon used for energy, and the others stored in plant stuctures. Thus, mangroves significantly contribute to climate change mitigation through carbon sequestration. This study aims to determine the carbon content of mangrove litter from Excoecaria agallocha species in the estuary of Sungai Tanggul, Sungai Nibung Village. Kubu Raya, West Kalimantan. The types of litter measured include leaves, fruits, twigs, and flowers, which were collecter using litter traps. The results showed the total carbon content of the litter was 7.49 tons/ha/year. The largest contribution from leaves litter (5.49 tons/ha/year), followed by twigs (1.90 tons/ha/year), and fruits (0.10 tons/ha/year),while flowers had an insiginificant carbon content.

Abstract

Temajo Island is renowned for its marine tourism activities and is home to a range of organisms, including algae. Microalgae serve as indicator species, offering insights into the aquatic environment through their species composition and abundance. This study aims to provide preliminary data on the abundance and some ecological indices (diversity, evenness, and dominance) of microalgae on Temajo Island, which will be the basis for assessing water conditions and supporting conservation efforts and sustainable management of natural resources. The research was carried out at four stations with different characteristics. At each station, surface water samples were collected using a plankton net. The microalgae in these samples were subsequently examined under a microscope, and their quantities were measured. The microalgae abundance ranged from 2.84 to 7,697.14 ind/L, with an average of 193.34 ind/L. Chaetoceros was the most abundant genus, followed by Rhizosolenia, Guinardia, Thalassiosira, Pseudo-nitzschia, and Bacteriastrum. The diversity index (H’) ranged from 2.67 to 3.08, indicating moderate to high species richness, while the evenness index (E) ranged from 0.64 to 0.74, reflecting a high level of uniformity among microalgae populations. The dominance index (C) varied between 0.11 and 0.20, suggesting low dominance by any single genus. These indices collectively indicate a balanced and diverse microalgae community, underscoring the ecological health and stability of the Temajo Island waters. Preliminary information about the species composition and abundance of marine microalgae in this study provides valuable insights into the dynamics of microalgae populations and their ecological implications in the marine ecosystems of Indonesia.

Abstract

Penata Besar Island is designated as one of the Coastal and Small Island Conservation Areas (KKP3K) in West Kalimantan, is a critical site for conserving coral reefs and reef fish. Currently, global climate change and anthropogenic activities have exacerbated coral reef bleaching worldwide. In the context of escalating global climate change and human-induced threats, this study evaluates the health condition of coral reefs in the northern waters of Penata Besar Island, Bengkayang Regency. An exploratory approach was employed, utilizing the Line Intercept Transect (LIT) method across four stations at two distinct depths (2-3 m and 5-6 m). The results revealed that coral cover varied with depth. At a depth of 2-3 m, live coral coverage was between 51.2% and 62.4%, classified as good, while at 5-6 m, coverage ranged from 30.4% to 49.4%, categorized as fair. Coral Massive (CM) was the predominant growth form observed. The diversity index (H') ranged from low to medium, the Evennes index (E) from medium to high, and the dominance index (C) was categorized as low. These findings highlight the varying health of coral reefs in different depths and provide a basis and essential insights for targeted conservation efforts.
