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.

Biodiversitas 19: 1558-1567. This research was carried out in a coastalarea of Semarang City, Central Java, Indonesia. It aimed to study the composition of plankton and benthos communities in silvofisheryponds, and to analyze the similarity in plankton and benthos composition between ponds as an indicator of variation in pondenvironmental quality. Nine pond treatments were sampled for their plankton and benthos composition. The nine treatments consisted ofa factorial combination of three mangrove species assemblages (Avicennia marina (M1), Rhizophora mucronata (M2), and a mixture ofboth (M3)) at three mangrove populations (5 trees (S1), 10 trees (S2), and 15 trees (S3)). Similarity index analysis was conducted tomeasure the impact of treatments on the plankton and benthos communities. The total number of plankton species identified inobservation periods in May, July and September of 2016, were 23, 16 and 21 species repectively, while for the benthos there were eightsomewhat different species identified in each of the three observation periods. Fluctuation in plankton and benthos composition tendedto achieve a balance in richness by the time of the the third observation period. Diatoms, particularly Gyrosigma sp., were the mostwidely distributed plankton in the first and third observation periods, while Pyramidella sulcata was the only well-distributed benthosspecies in the three observation periods. Pairwise similarity indices between treatments ranged from 0% to 62.5% for plankton and from16.7% to 100% for benthos. The results of the investigation suggested that mangrove species affected plankton and benthos speciesrichness in this initial stage of a silvofishery development: plankton composition appeared to be richer in ponds with A. marina, whilebenthos was richer in ponds with R. mucronata.

Studi mengenai ekopreferensi dan dua jenis mangrove (Avicennia marina dan A. alba) dilakukan di tegakan mangrove muara sungai Wulan, Demak. Tujuan penelitian ini diarahkan untuk melihat kemampuan ekopreferensi A. marina dan A. alba terhadap salinitas, jenis sedimen dan kandungan air. Data vegetasi diperoleh dengan menggunakan transek garis yang dikombinasikan dengan cara kuadrat yang dimodifikasi dari Cox (1967) dan Mueller-Dumbois & Ellenberg (1977). Dua stasiun pengumpulan data vegetasi ditentukan secara horisontal dari garis pasang terendah sampai garis pasang tertinggi. Pengukuran parameter lingkungan dilakukan pada transek yang ada dan tanah sampel dianalisis untuk melihat fraksi tekstur. Hasil analisis menunjukkan bahwa dalam hal keragaman vegetasi, tegakan mangrove yang ada di muara Sungai Wulan miskin dalam hal komposisi jenis dibandingkan dengan tegakan mangove yang ada di sepanjang pantai utara Jawa Tengah. Studi ini juga menunjukkan bahwa kehadiran A. marina cenderung menjadi species pelopor dibandingkan dengan A. alba. Diduga hal ini disebabkan oleh kemampuan A marina untuk beradaptasi pada kondisi salinitas dan tipe tanah yang marginal. Kata kunci: Bakau, ekopreferensi, A. marina, A. alba, Muara Sungai Wulan A b s t r a c t Study on ecological preferences of two Avicennia species was carried out in Wulan River, Demak, Central Java. The sudy was aimed at revealing the eco-preference toward salinity, sediment types and water content. Vegetation data were collected by implementing line transect approach combined with quadrate methods modified according to Cox (1967) and Mueller-Dumbois & Ellenberg (1977). Two sites for vegetation data collection were set horizontally from High Tide Mark toward Low Tide Mark. All ecological parameters were measured in situ on the established transects.  The results showed that in term of mangrove species diversity this area is low or marginally poor compared to other mangrove belts along the northern coast of Central Java. The study also showed that the two Avicennia species  are the pioneer species. These two species of Avicennia are adaptable to the salinity and soil types that are poor in term of nutrients content.

Mangrove is the largest ecosystem in Berbak-Sembilang National Park (BSNP) South Sumatra. Mangrove has capability to absorb carbon dioxide through photosynthesis then store it in biomass, that known as Carbon sink. The purpose of this research was to estimate the ability of carbon fixation through the photosynthesis mechanism in the mangrove area of BSNP South Sumatra. This study was conducted in July-August 2017, at 12 observation stations. Data of carbon fixation through photosynthesis was estimated by using Leaf Area Index (LAI) method. The estimation of carbon fixation by photosynthesis was done for 17 dominan mangrove species in BNSP South Sumatera. The average amount of carbon absorbed by mangrove vegetation through photosynthesis mechanism in BNSP South Sumatera was 204.91 kg/ha/day. Avicennia marina and Rhizophora apiculata were the mangrove community that showed highest capability to absorb carbon through photosynthesis around 553.43 kg C/ha/day and 401.99 kg-C/ha/day, respectively. Individually, B. cylindrica had the highest capability of carbon fixation by photosynthesis mechanism (10.95 kg-C/ha/day). Our research recommended three mangrove species (A. marina, R. apiculata and B. cylindrica) for restoration species to increase carbon sink in BNSP South Sumatera based on their photosinthesis performances.

Ariyanto D, Bengen DG, Prartono T, Wardiatno Y. 2018. Short Communication: The relationship between content of particular metabolites of fallen mangrove leaves and the rate at which the leaves decompose over time. Biodiversitas 19: 730-735. Fallen mangrove leaves contain metabolites that play a role in their decomposition in coastal conditions. This research was conducted from September 2016 to February 2017 in Pasar Banggi, Rembang, Central Java, with the purpose of investigating the impact of the leaf metabolites of various mangrove species on the rate of decomposition of the leaves in exposed litter bags The results suggested that secondary metabolites are closely involved in the decomposition of the mangrove leaves. The fastest rate of decomposition was found in Avicennia marina, and the slowest in Rhizophora stylosa. The leaves of A. marina required 10 days (half-life, t50) to decompose by 50% and this was closely related to the phosphorus content of the leaves. On the other hand, R. stylosa required 24 days (half-life, t50) to decompose by 50%.

Setyawan. 2018. Diversity of mangrove vegetation and carbon sink estimation of Segara Anakan Mangrove Forest, Cilacap, Central Java, Indonesia. Biodiversitas 19: 246-252. Mangrove forests are known as standing stores of sequestered atmospheric carbon. The role of mangrove forests in the sequestering substantial amount of atmospheric carbon dioxide (CO2) and storing the carbon in its biomass has been recently underscored. This research aimed to estimate vegetation diversity and carbon sink potential of Segara Anakan Mangrove Forest Cilacap, Central Java from August-December 2012. Vegetations sampling was done by square plots technique. Diversity index was utilized to determine species diversity. Allometric equations were used to estimate biomass and carbon sinks. This study only calculates aboveground biomass and carbon sinks. The research results showed that mangrove in Segara Anakan was composed of 24 species with 19 families, consisting of 16 species of trees, 14 species of saplings and 16 species of herbs. The most dominant tree was Avicennia marina with importance value of 43.62% in Kembang Kuning, 60.27% in Ujung Alang and 25.6% in Klaces. The most dominant of sapling was Avicennia marina, with an important value of 31.1%. The total biomass of a tree is about 43.06 kg/tree or 0.13 ton/ha. Total biomass of sapling was 27.38 kg/tree or 0.32 ton/ha. The carbon sink of the tree was 49.10 ton/ha and carbon sink of sapling was 79.39 ton/ha. It can be concluded that Segara Anakan Mangrove forest is very important as a carbon sink in South part of Central Java, Indonesia.
