ANALISIS PRODUKSI  SERASAH MANGROVE  DI PANTAI MANG KALOK KABUPATEN BANGKA

Ekositem mangrove merupakan ekosistem pesisir yang memiliki peran dan fungsi ekologis penting dalam menunjang sumber daya perairan dan perikanan. Keberadaan ekosistem mangrove yang lestari dan sehat tidak dapat dipisahkan oleh suplai kandungan bahan organik yang berasal dari serasah mangrove. Serasah merupakan guguran struktur vegetatif dan reproduktif yang disebabkan oleh faktor ketuaan, stress oleh faktor mekanik, ataupun kombinasi dari keduanya dan kematian serta kerusakan dari keseluruhan tumbuhan oleh iklim (hujan dan angin). Tujuan dari penelitian ini adalah untuk mengetahui produksi serasah daun mangrove, membandingkan produksi serasah beberap jenis mangrove yang dominan terdapat di Pantai Mang Kalok, serta mengetahui nilai parameter lingkungan yang berkaitan dengan serasah. Penelitan ini dilaksanakan pada bulan Januari-Maret 2018 bertempat di Pantai Mang Kalok, Kecamatan Sungailiat, Kabupaten Bangka. Metode yang umum digunakan untuk pengambilan produksi serasah adalah metode litter-trap (Jaring penampung serasah). Produksi serasah daun mangrove di Pantai Mang Kalok lebih banyak dihasilkan dari jenis Ceriops decandra dengan massa 185,7gr/m2/30hari dibandingkan dengan jenis Rhizophora mucronata yang hanya memproduksi 119,6gr/m2/30hari. Adapun untuk total produksi serasah daun mangrove di Pantai Mang Kalok adalah 305,3 gr/m2/30hari atau 10,17 gr/m2/hari. Sedangkan parameter lingkungan menujukan kondisi perairan Pantai Mang Kalok masih baik dan dapat mendukung proses penyerapan bahan organik dari serasah daun mangrove.ANALYSYS OF MANGROVE LITTER PRODUCTION ON MANG KALOK BEACH, BANGKA REGENCY. The mangrove ecosystem is a coastal ecosystem that has important ecological roles and functions in supporting marine resources and fisheries. The existence of a sustainable and healthy mangrove ecosystem cannot be separated by the supply of organic matter from mangrove litter. Litter is vegetative and reproductive structures avalanches caused by the factor of aging, stress by mechanical factors, or a combination of both and the death and destruction of the whole plant by the climate (rain and wind). The purpose of this study was to determine the production of mangrove leaf litter, compare the production of litter of several dominant types of mangrove found in Mang Kalok Beach, and to determine the value of environmental parameters related to litter. Research was conducted in January until March 2018 in Mang Kalok Beach, District Sungailiat, Bangka. A common method used for making the production of litter is litter-trap method (Net container litter). The production of mangrove leaf litter in Mang Kalok Beach is more produced from the type Ceriops decandra with a mass of 185.7gr / m2 / 30 days compared to the type of Rhizophora mucronata which only produces 119.6gr / m2 / 30 days. The total production of mangrove leaf litter at Mang Kalok Beach is 305.3 gr / m2 / 30 days or 10.17 gr / m2 / day. While the environmental parameters show that the condition of Mang Kalok Beach is still good and can support the process of absorption of organic matter from mangrove leaf litter.

Production and decomposition of mangrove litter could contribute organic matter and nutrients to the coastal waters. This study was to estimate the extent to which the rehabilitated mangrove of Rhizophora mucronata and Sonneratia alba contribute organic matter. This study was conducted from November 2015 to January 2016. Litter traps were used to collect the litter production and litterbags to measure decomposition rates. The results showed that the average of litter production for Sonneratia alba and Rhizophora mucronata was 4,38 g.m-2.day-1 and 3,61 g.m-2.day-1, respectively. However, Sonneratia alba apparently showed higher decay rates compare with Rhizophora mucronata. Nutrients element (N and P) released were 321,2 kg.ha-1.years-1 and 47,45 kg.ha-1.years-1 for Sonneratia alba; and 131,4 kg.ha-1.years-1 and 13,14 kg.ha-1.years-1 for Rhizophora mucronata. Overall, this study indicated that the mangrove rehabilitation in the area study contributed insignificantly carbon restocking the affected area, although it was able to provide ecological functions of this mangrove ecosystem.

Abstract The mangrove ecosystem is one of the coastal ecosystems that has important ecological roles and functions in supporting marine and fishery resources. Marine and fisheries resources are largely determined by the contribution of mangrove litter. The aims of this study was to determine the production of Rhizophora mangrove leaf litter in Sungai Bersejarah mangrove ecosystem, and to determine the value of environmental parameters related to litter. The research was conducted in January until March 2021 in Sungai Bersejarah mangrove area Kayu Ara Permai, Siak Regency. Line transect plot were used to calculate the density of Rhizophora. Rhizophora litter production was measured using the trap net method placed at three sampling site. Three litter trap nets measuring 1 m x 1 m are placed at each station. Rhizophora tree density ranges from 316 - 444 ind./ha. The production of Rhizophora mangrove leaf litter in Sungai Bersejarah mangrove ecosystem was 0.82 – 1.39 g/m2/day (3.00 – 5.09 ton/ha/year), average was 4.11 ton/ha/year. Analysis of variance test showed that there was a significant difference in Rhizophora leaf litter production between sampling points with different Rhizophora tree densities (p<0.05). Mangrove vegetation density has a moderate relationship (r=0.43) to the production of Rhizophora mangrove leaf litter. Environmental parameters indicate that the condition of the Sungai Bersejarah mangrove ecosystem is still good and can support the life of mangrove vegetation.

The litterfall and decomposition represent the main transfer of organic matter and nutrients from the vegetation to the soil surface and determine positive trajectories in the process of rehabilitating and restoring degraded ecosystems. The aim of this study was to evaluate the contributions of organic materials and nutrients through the characterization of fine litter in an urban dry forest fragment. Litter production was monitored for one year by collecting 29 traps (0.5 m2). To evaluate leaf nutrient resorption, green leaves were collected from 5-10 individuals that represented the dominant tree species. Litter-bags (20 x 20 cm, 2 mm pore) were used for six months to evaluate the decomposition of leaf litter. Annual fine litter production was found to be 8 574 kg ha-1, with the Cordia alba species contributing the most leaf litter (1 134 kg ha-1) and nutrients (N: 6.16; P: 0.21; Ca: 4.72; Mg: 0.47; K: 1.27 kg ha-1). Decomposition rates (k constant) followed the decreasing order: C. alba (k: 4.6) > Machaerium milleflorum (k: 3.5). M. milleflorum and Albizia niopoides presented a pattern of rapid N and P release in the first 30 days, with more than 80 % and 60 % released from M. milleflorum and C. alba, respectively, by the end of the experiment. The litterfall monitoring carried out in this urban dry forest fragment revealed some important aspects of the functioning of an ecosystem as seriously threatened as the tropical dry forest. Rev.

<strong>Decomposition Rate of Leaf Litter in The Mangrove Ecosystem of Kelong Island, Bintan Regency.</strong> The mangrove forests in the southeastern part of Kelong Island have abundant carbon reserves that indicate high primary productivity areas. Decomposition of leaf litter, as a part of regional productivity, produces simple essential nutrients utilized to sustain the growth of mangroves. The purpose of this study was to determine the decomposition rate of leaf litter in each zone of the study, the Landward (L), Middlezone (M), and Seaward (S) which is distinguished by the abundance of plant species and in situ environmental parameters. The experiment was conducted in March–May 2015 in the mangrove areas of Island Kelong, Bintan regency. The decomposition process was observed at six time intervals, i.e. 2, 4, 7, 14, 28, and 42 days using net bag containing 10 g of wet leaves placed on the substrate surface. The results showed that L was a zone with highest percentage of decomposition (56.34 ± 20.58%) compared to the M and S, respectively for 51.59 ± 15.46% and 51.09 ± 8.70%. The highest rate of litter decomposition in zone L was 1.40 ± 0.82 g·m-2·day-1 that was significantly different from the zones M and S, respectively of 0.83 ± 0.89 g·m-2·day-1 and 0.78 ± 0.70 g·m-2·day-1. Analysis of the coefficient of decomposition rate (k) indicated that the rate of decomposition in this region was high (k > 0.01). The decomposition rate has a significant correlation with the abundance of mangrove species, the salinity value of the water, and soil temperature.

Leaf Litter Production

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production. Keywords: biomass fraction, seasonal litter production, West Muna Regency

Annual net N mineralization in the 0–10 cm mineral soil zone of nine forest stands on silt–loam soils was measured using a series of insitu soil incubations from April 1980 through April 1981. Differences in soil organic matter (SOM) dynamics among sites were shown with net N mineralization ranging from 0.54 to 2.10 mg N mineralized•g SOM−1•year−1. This variation was not related to percent N in SOM. Net N mineralization varied seasonally with maximum rates in June and very low rates in winter. Nitrification rates were constant from May through September despite fluctuations in soil ammonium pools. Nitrification was greater than 50% of annual net N mineralization at all sites. N uptake by vegetation, as estimated by net N mineralization plus mineral N inputs via precipitation, with minor corrections for mineralization below the incubation depth and for mineral N losses to groundwater, ranged from 40.3 to 119.2 kg N•ha−1•year−1. Annual leaf and needle litter production ranged from 2.12 to 4.17 Mg•ha−1•year−1 and was strongly correlated with N uptake (r = 0.938, P < 0.01). N returned in leaf litter was also correlated with N uptake (r = 0.755, P < 0.05). Important feedbacks may exist between N availability and litter quality and quantity.

The bacterivores nature of ciliates in mangrove leaf litters, increase the mineralization and making nutrients more available to the next trophic level. This study was conducted to access the species composition, diversity and abundance of ciliates in mangrove leaf litters. Monthly samples were collected for one year (June 2014 – May 2015) from ten selected stations. Eight physicochemical variables such as temperature, dissolved oxygen, pH, conductivity, chloride, sulfate, nitrate, and phosphate were also monitored during the study. Taxonomic studies recorded 115 species of ciliates belonging to 16 subclasses, among them Peritricha represent the subclass having the maximum species number and abundance followed by Suctoria. Vorticella companula records the maximum abundance and dominance index followed by Euplotes minuta. Analyzing the seasonal distribution of ciliates, a maximum number of species were recorded during post-monsoon and minimum during monsoon. The study establishes the distributional difference, diversity and abundance of peritrich ciliates on mangrove leaf litters according to seasonal fluctuations. Multivariate statistical analysis of different environmental parameters regarding species diversity and abundance of mangrove ciliates, it was found that the environmental parameters have an impact on the distribution and diversity of ciliates in mangrove leaf litters. The study signifies the importance of leaf litters and environmental variables in the dynamics of ciliates composition and abundance.
