Tannins in mangrove plants in Segara Anakan Lagoon, Central Java, Indonesia
Summary
This study measured tannin content in mangrove plants from a lagoon in Indonesia, finding variation across species and sites. Mangrove tannins have industrial and ecological significance, and these baseline measurements support conservation and sustainable use of mangrove resources.
Abstract. Hilmi E, Sari LK, Siregar AS, Sulistyo I, Mahdiana A, Junaedi T, Muslih, Pertiwi RPC, Samudra SR, Prayogo NA. 2021. Tannins in mangrove plants in Segara Anakan Lagoon, Central Java, Indonesia. Biodiversitas 22: 3508-3516. Mangrove tannin is polyphenol compound and extractive matter in mangrove vegetation. Mangrove tannins have the potentials to support paint industry, animal feed, tanners and wood adhesives industry. This research is aimed to investigate the mangrove species in Segara Anakan, Central Java, Indonesia that produce tannins, and to analyze the distribution and contents of tannin in the part of mangrove plant. A total of 342 samples from 19 mangrove species was collected from 37 sampling points in Segara Anakan. UV-Visible Spectrophotometry was used to analyze the tannin content in the samples. The results showed that the tannins contained in bark and stems were higher (66.6%) than those in leaves (33.4%). Mangrove vegetation can be classified into five classes in terms of tannin percentage with Heritiera littoralis, Nypa fruticans, and Rhizophora mucronata had highest tannin percentage. The clustering analysis of mangrove tannin showed that Ceriops decandra-Ceriops tagal, Acacia auriculiformis-Sonneratia alba, Sonneratia caseolaris-Xylocarpus granatum, and Avicennia marina-Rhizophora apiculata had high similarity of tannin percentage. The distribution of tannins in mangrove species is as follow: 0.59-10.14 kg trees-1 (bark and stem of mangrove diameter > 10 cm) and 0.20-3.74 kg trees-1 (leaves of mangrove diameter > 10 cm) until 8.84-158.96 kg trees-1 (bark and stem of mangrove diameter > 40 cm) and 4.60-91.65 kg trees-1 (leaves of mangrove diameter > 40 cm). R. mucronata and R. apiculata had the highest total tannin content, ranged between 386.60-460.38 kg trees-1.

Profil Pencemaran Mikroplastik Pada Sedimen Ekosistem Mangrove di Pulau Serangan, Bali
Indonesian researchers measured microplastic contamination in mangrove sediments at Serangan Island, Bali, sampling across different depths and land-use types to map the distribution of plastic particles in this coastal ecosystem. Mangroves act as natural plastic traps due to their dense root networks, making them important sentinels for monitoring coastal plastic pollution.
