Ground Biomass

Mangrove forest has an important function for living thing especially in the ocean and coastal area. Besides as feeding and nursery ground, mangrove forest is also has a function as carbon sinker. The utilizing of mangrove forest as a corbon sinker is one of ways to reduce CO2 in atmosphere. Mangrove forest in Oebelo village has a capability to utilize as carbon sinker. The aim of this research was to estimate above ground biomass and carbon reserve from two mangrove species Avicennia marina and Rhizopora mucronata in coastal area of Oebelo Village. In this research data was collected from diameter breast high and litter from forest floor. Alometric was used to estimate the above ground biomass. After data collected, analysis would continue with t test to know the different between these two species.The result showed A. marina and R. mucronata were different, the highest biomass, carbon reserve and CO2 sequestration were in A.marina respectively 118.80 Mg.ha-1, 54.65 Mg.ha-1, 200.37 Mg.ha-1 and R. mucronata respectively 28.90 Mg.ha-1, 13.30 Mg.ha-1, 48.75 Mg.ha-1. The result for litter biomass and carbon reserve showed there was no different between these tow species.

The aim of this research is to make a map of mangrove forest distribution and to know the dynamics of mangrove forest distribution in the coastal area of Tobelo, North Halmahera Regency. The method used is descriptive quantitative and data analysis using Geographic Information Systems (GIS) with ArGis 10.6 software. The research data were processed from the base map and Landsat 7 imagery data for the period 2000-2020. The result of the analysis shows that there is a change in the distribution of the mangrove coastal mangrove Tobelo within 20 years. In the Landsat 7 level 1 image data, from 2000-2015 the mangrove forest experienced a lot of reduction, while in 2020 the mangrove forest on the Tobelo coast experienced an increase compared to previous years.

Secara geomorfologi relatif datar yang tersusun dari proses proses fluvial dan proses asal laut sebagai endapan dataran banjir, endapan alur sungai, endapan estuari dan endapan laut. Endapan limpah banjir tersusun oleh lempung lanauan dan lempung kadang dijumpai adanya kerakal dan brangkal, dimanfaatkan oleh masyarakat sebagai Sawah, tanaman padi. Pasir, karekal dan berangkal merupakan material penyusun endapan alur sungai. Estuari terdiri dari material organik dan lempung. Daerah ini tertutup oleh hutan mangrove dan tambak. Endapan laut didominasi endapan yang berukuran halus lempung dan pasir (halus – kasar) dengan dibeberapa tempat kadang dijumpai pecahan cangkang.Kata kunci: Cilamaya, Kawasan Pesisir, estuariCoastal area in the northern of Java island is part of the always changes caused by hidrometeorogy aspect include the Cilamaya costal area.

The floodplain deposits consists of silty clay and clay some time with pebble, use for the paddy field and some urban area. Sand, pebble and coble are from the river (channel).

Mangrove forest was a tropical and sub tropical forests vegetation. It dominated by some of mangrove trees which it growed and developed in the tidal muddy along the coastal area.  The mangrove forest of Merak Belantung of South Lampung  had some commodities which it had a economic value and could benefits for the community.  The economic value information aimed by interview the respondents.   The economic comodities of mangrove were fishes namely: kakap (Lutjanus sp.), belanak (Valamugil seheli), gelodok (Periophthalus modestus), and varieties of seashells (tiram (Crassostrea gigas) and lukan (Geloina erosa)), crabs (Brachyura), shrimp (Penaeusmonodon), and sonneratia fruit (Sonneratia caseolaris).  The economic value of commodities could discovered and calculated with assessment based on market valuation and willingness to accept payment (WTA) methods.  Total economic value from mangrove forest commodities was IDR 754.090.000/year from 8 types commodity. Key word  :     mangrove forest commodity, assessment based on market value, willingness to accept (WTA)

Holocene Foraminiferal fauna at the area of Phan Vinh island, Truong Sa archipelago is relatively abundant and diverse in both taxonomic composition and ecological characteristics. The initial research results have identified 69 species (excluding several ones unidentified) belonging to 42 genera, 25 families and 6 orders. Among them, the representatives of the genera of Calcarina, Amphistegina, Heterostegina, Elphidium, Amphisorus, Marginopora, Sorites, Parasorites, Peneroplis, Archaias, Siphonipheroides, Septotextularia are predominant. They characterized by the shallow, transparent and warm marine environments of the region of Truong Sa archipelago during Holocene. Some problems related to this fauna at the area of Phan Vinh island such as biodiversity of coral-reef ecosystems, stratigraphic and paleogeographical significances, and its role of reef - building are also mentioned in this article. In addition, for the modern Foraminifera in the world, today they are being used as ‘biomarkers’ (bioindicators) in assessing and monitoring environmental quality of coral reef ecosystems in particular and marine environment in general. In Vietnam, this method has not been applied, but in the future, this is one of the methods that should be concerned. In addition, in aquaculture the Foraminifera is also a source of nutrition that should not be ignored.

Coastal Area Management

ABSTRACTThe northern part of Karawang is a coastal area with mostly mud-sand substrates. This substrate tends to be unstable, so that naturally, this kind of sediment is supported by coastal vegetation that forms coastal ecosystems, such as mangroves; therefore, the importance of mangroves in Karawang coast is definite. Unfotunately the data regarding the condition of mangroves in Karawang Regency is quite insufficient. This information, especially about its existence, is needed as a database for further research and as basis to support government policies on coastal area management. The aim of this research is to provide information about the existence of mangrove in Karawang Regency. The method is by using Normalized Different Vegetation Index (NDVI) calculations on Landsat 8 2018 satellite imagery of Karawang to get the data that reveal the information. We have discovered that the existing of mangroves in Karawang Regency in 2018  is 305,14 Ha. Border coast that is vegetated is only 33.75 km of 77 km long coastline of Karawang. Only less than 5% of the total mangrove protected area in Karawang Regency is detected as mangrove from the total 9.055 Ha of the area.
