Abstract

Seagrass ecosystems services in the coastal waters are included as primary producers, nutrient recycler, bottom stabilizers, sediment traps, and erosion barriers. Gleaning fisheries in seagrass bed in Mokupa waters could cause damage on seagrass, that can be marked by changes in seagrass cover. The purposes of this study were to identify the types of seagrasses and to determine the health condition of seagrass bed ecosystem in Mokupa waters. The research method used in this study is quadrat transect method. Data collection was carried out by laid three transects (100 m) with distance between each transect was 50 m. A square frame (50×50 cm2) which is divided into 4 squares is placed on the right side of the transect, with 10 m distance between frame. This study found four types of seagrasses, namely Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia and Halophila ovalis. E. acoroides have the highest percentage cover (16.19%) followed byT. hemprichii (6.91%), H. pinifolia (4.50%) and H. ovalis (1.56%) respectively. Seagrass cover in the study area is considered medium (26-50%) while the health condition was poor (29.25%).

Abstract

Mangrove forests have a role as an absorber of carbon dioxide (CO2) from air and sea therefore they play an important role in mitigating climate change. The problems that exist today are the decline in the area of mangrove forests due to the conversion of land functions into ponds, and development in coastal areas. Decrease of mangrove forest areas can lead to reduced its ability to absorb and storage carbon dioxide (CO2). The purposes of this study were to analyze litter carbon content of mangrove leaf litter in the mangrove forest of Pontoh Village, Wori District, North Minahasa Regency and estimate the carbon content (C) in mangrove litter per hectare per year. Based on the results of the analysis, the total average percentage of carbon content in mangrove litter in Ponto Village, Wori District, North Minahasa Regency was 29.71% C/day, and from the estimation results, the average carbon content (C) in mangrove litter is 3.68 tons/ha/year. Key Word: mangrove, litter, carbon content ABSTRAK Hutan mangrove memiliki peran sebagai penyerap karbondioksida (CO2) dari udara sehingga berperan penting untuk mitigasi perubahan iklim. Permasalahan yang ada saat ini yaitu berkurangnya luas kawasan hutan mangrove akibat pengalihan fungsi lahan menjadi tambak, dan pembangunan di kawasan pesisir. Apabila berkurangnya kawasan hutan mangrove maka dapat menyebabkan berkurangnya sumber penyerapan dan penyimpanan karbodioksida (CO2). Adapun tujuan dari penelitian ini yaitu untuk menganalisis kandungan karbon pada serasah daun mangrove hutan mangrove Desa Lansa, Kecamatan Wori, Kabupaten Minahasa Utara dan mengestimasi Kandungan Karbon (C) pada serasah mangrove per luasan hektar per tahun. Berdasarkan hasil analisis didapatkan total rata-rata persentase kandungan karbon serasah mangrove di Desa Ponto, Kecamatan Wori, Kabupaten Minahasa Utara yakni sebesar 29,71% C/hari, serta dari hasil estimasi didapatkan rata-rata kandungan karbon (C) pada serasah mangrove sebesar 3,68 ton/ha/tahun.

Abstract

Mangroves are plants that are able to survive in coastal areas under environmental conditionsthat are influenced by tides and muddy seawater. Mangrove forests have an ecological function, whichis to play a role in efforts to mitigate global warming because mangrove forests absorb and store carbondioxide (CO2) which is carried out through the process of photosynthesis and storing it in biomass stock.There are 2 objectives of this study, namely: (1) to estimate the carbon stored in mangrove vegetationin Likupang District, North Minahasa Regency (2) to find out how much potential carbon stock is storedin mangrove vegetation and absorption of carbon dioxide (CO2) on mangrove stands. The method usedin this study was a sample plot transect line (Dharmawan and Pramudji, 2001). Based on the resultsobtained from the calculation of the biomass and carbon stock stored in mangrove vegetation inLikupang District, North Minahasa Regency, it can be seen that the average value is 452.42 tons/hawith a carbon content or the amount of carbon stored is 212.64 tons C/ ha or equivalent to 780.38 tonsof CO2/ha.Keywords: Mangrove Vegetation, Carbon, North Minahasa ABSTRAKMangrove merupakan tumbuhan yang mampu bertahan hidup di daerah pesisir pantai dengandi bawah kondisi lingkungan yang dipengaruhi oleh pasang surut air laut dan berlumpur.

Abstract

Mangroves play an important role in supporting life in coastal and marine areas. As plants that live in marine and land areas, mangrove forests transfer various kinds of nutrients both on land and into the sea. Decreasing area of mangrove forests leads to a decrease in mangrove litter production. Mangrove litter has a function as a carbon sink and storage. The purpose of this study was to determine the percentage of carbon content (C) and estimate the amount of carbon stored in the leaf litter of mangrove Rhizophora spp., in the mangrove forest of Wori Village, Wori District, North Minahasa Regency. The Litter-trap method (litter trapping net) was used in this study. Litter collection was carried out for 28 days in 12 litter-traps measuring 1x1 m2. All litters trapped in the litter-trap were weighed in their wet and dry weight, then analyzed in the laboratory to determine the carbon content. Based on the results of the analysis, the total average percentage of carbon content in mangrove litter 25.93% C, and from the estimation results, the average carbon content (C) in the litter is 19.99 tons/ha/year. Keywords: Mangrove, Litter, Litter-Trap, Carbon Content, Wori Village ABSTRAK Mangrove merupakan ekosistem yang berperan penting dalam mendukung kehidupan di wilayah pesisir dan kelautan. Sebagai tumbuhan yang hidup di wilayah laut dan darat, hutan mangrove mentransfer berbagai macam nutrien baik ke darat maupun ke laut. Berkurangnya luasan hutan mangrove menyebabkan produksi serasah mangrove juga berkurang. Serasah mangrove memiliki fungsi sebagai penyerap dan penyimpan karbon.Adapun tujuan dari penelitian ini yaitu untuk mengetahui persentase kandungan karbon (C) dan Mengestimasi jumlah karbon yang tersimpan pada daun serasah mangrove Rhizophora spp., di hutan mangrove Desa Wori, Kecamatan Wori Kabupaten Minahasa Utara.Pengambilan sampel pada penelitian ini menggunakan metode Litter- trap (jaring penangkap serasah). Pengumpulan serasah dilakukan selama 28 hari dalam 12 Litter-trap yang berukuran 1x1 m2 . Seluruh serasah yang terperangkap di dalam litter-trap di timbang berat basah dan berat keringnya, kemudian dilakukan analisis di Laboratorium untuk mengetahui kandungan karbon. Berdasarkan hasil analisis didapatkan total rata-rata persentase kandungan karbon serasah mangrove yakni sebesar 25,93 % C, serta dari hasil estimasi didapatkan rata-rata kandungan karbon (C) pada serasah sebesar 19,99 ton/ha/tahun.
