“…Stations 1, 2, and 3 are located exactly on the Citanduy River flow heading to the sea, resulting in low organic substance content, TSS and high turbidity. Citanduy River is one of the main sediment suppliers in Segara Anakan (Usman et al 2005) with a sedimentation increase rate of 41.2 ha year -1 (Sari et al 2016). According to Kennish (1990), deposit-feeding organisms will replace suspended feeding organisms in waters conditions with high TSS content due to the disturbances in the functions of filter, vision, and respiration (Nybakken 1993 andKennish 1990).…”

Abstract. Rimadiyani W, Krisanti M, Sulistiono. 2019. Macrozoobenthos community structure in the Western Segara Anakan Lagoon, Central Java, Indonesia. Biodiversitas 20: 1588-1596. Anthropogenic activity along the river and around the coastal area will potentially generate waste as it can cause the decline of water quality and affect the lives of macrozoobenthos. This study aimed to study macrozoobenthos community structure in western Segara Anakan Lagoon and its relationship with water physical-chemical quality. The study was conducted from June to November 2016, at six stations of the lagoon. Macrozoobenthos obtained during the study consisted of four phyla (Annelida, Mollusca, Crustacea, and Sipuncula), six classes, and 33 genera. The highest abundance of macrozoobenthos was at Station 6 (193 ind./m2) dominated by Malacostraca and the lowest abundance of macrozoobenthos was at Station 1 (13 ind./m2) dominated by Bivalvia. Diversity, Evenness and dominance indices of the macrozoobenthos were 0.0-2.0, 0-0.8, and 0.4-1.0, respectively, indicating a medium ecologically stressed. Mud substrate condition with high percentage of organic material affected the community structure of the macrozoobenthos expressed by a high density and diversity, but low dominance indices.

“…Based on land cover, density of trees, abrasion, sedimentation (Sari et al, 2016;Syakti et al, 2013), abrasion and intrusion (Hilmi, 2018;, the mangrove density in Meranti Island had category as the mangrove degradationn, especially station 2 (rare and high degradation). The mangrove degradation in Meranti Island could be caused by (1) the exploitation of commercial mangrove like as Rhizophora spp and Bruguiera spp.…”

“…(4) The social opinion of low value of mangrove ecosystem can accelerate degradation of mangrove ecosystem and conversion of mangrove in Meranti Island . and Sari et al (2016) emphasis that the degradation of mangrove ecosystem also was caused by the decreasing of total economic value from mangrove ecosystem. The degradation of mangrove ecosystem decrease supporting of spawning, feeding and nursery ground for phytoplankton and zooplankton (Cadier et al, 2016;Kruk et al, 2016;Masuda et al, 2017), loosing of the phytoplankton and zooplankton habitat's.…”

The abundance of phytoplankton and zooplankton have correlation with mangrove conditions in coastal area. The mangrove degradation give negative impact for abundance and diversity phytoplankton and zooplankton. The research aimed to analysis and construct prediction model of abundance and biodiversity of phytoplankton and zooplankton in mangrove ecosystem. The research used the transect method (to determine mangrove density), filtering method (to analyze abundance of phytoplankton and zoopankton) and statistical method (to develop estimation modeling of plankton abundance). The results showed that (1) the mangrove density between 250 trees/Ha - 1250 trees/Ha (2) the phytoplankton abundance were 10.675 Indv/L (in mangrove rarely) - 24.290 indv/ L (in mangrove high density), (3) the zooplankton abundance were 261 Indv/L (in mangrove rarely) - 2.204 indv/L (in mangrove high density) (4) The modelling analysis showed that (1) the phytoplankton abundance (y) = 0.0303 x2 - 22.059 x + 13004 and (2) the zooplankton abundance (y) = 0.0057x2 – 5.39 x + 1458.2, with x = mangrove densityKeywords: phytoplankton and zooplankton, mangrove density, abundance, estuary and lagoon

“…Mangrove is vegetation of intertidal zones between marine and terrestrial ecosystems (Bellotti et al 2012;Wang et al 2018;Yang et al 2018) has many ecosystem services such as carbon sequestration Hilmi et al 2019b), reducing coastal disasters (Hilmi 2018;Suhendra et al 2018), water conservation, pollution reduction (Hilmi, Sari, and Setijanto, 2019;Sari et al 2016;Su et al 2012;Syakti et al 2013a,b), bioremediation (Hidayati et al 2011;Syakti et al 2013a) and provide tannin as non-timber forest product. As the non-timber services, tannin has an important value similar with function to reduce coastal disaster (Hilmi 2018), heavy metal pollution (Syakti et al 2013a;, support REDD program ) and activity of conservation and economic carbons (Canu et al 2015;Avelar et al 2017;.…”

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.
