“…Kawasan ini mencakup 23% ekosistem mangrove dunia (Giri et al, 2011). Keberadaan ekosistem mangrove yang secara alami memberikan jasa lingkungan yaitu mencegah erosi dengan menahan dan memecah gelombang serta dapat memperbaiki kerusakan dan mengurangi pencemaran yang ada di pantai (Akbar et al, 2017) Ekosistem mangrove Batu Ampar terletak di muara sungai terpanjang di Indonesia yaitu Sungai Kapuas. Ekosistemnya memiliki permasalahan seperti halnya ekosistem mangrove pada umumnya yang mengalami tekanan akibat pertumbuhan penduduk (Pramudji 2000).…”

“…Hubungan sosial ekonomi, pengetahuan, dan persepsi masyarakat tentang partisipasi masyarakat dan rehabilitasi lingkungan tidak akan selalu berjalan harmonis. Beberapa faktor yang mempengaruhinya antara lain ketidaksesuaian manfaat ekonomi langsung kepada masyarakat dan persepsi bahwa pemerintah bertanggung jawab dalam menjaga lingkungan (Ritohardoyo et al, 2017). Selain itu, informasi valuasi ekonomi juga berguna sebagai dasar untuk membuat kebijakan pengelolaan ekosistem mangrove bagi stakeholders (Thompson dan Friess, 2019).…”

Ekosistem mangrove Batu Ampar terletak di muara sungai terpanjang di Indonesia yaitu Sungai Kapuas. Ekosistemnya memiliki permasalahan seperti ekosistem mangrove pada umumnya yang mengalami tekanan akibat pertambahan penduduk. Sebagian besar masalah tersebut merupakan dampak penggunaan lahan oleh masyarakat sekitar ekosistem. Penelitian ini bertujuan untuk menguji pengaruh kondisi ekosistem mangrove terhadap partisipasi masyarakat dan valuasi ekosistem mangrove berupa ekowisata dan hutan desa di Kecamatan Batu Ampar, Kalimantan Barat. Desa-desa yang diteliti berdasarkan intensitas pengelolaan ekowisata mangrove, dari yang paling lama hingga yang terbaru, yaitu Batu Ampar, Nipah Panjang, dan Medan Mas. Penilaian jasa ekosistem mangrove dihitung berdasarkan Total Economic Value (TEV) yang meliputi manfaat langsung, tidak langsung, keberadaan, dan pilihan. Valuasi mangrove untuk tiap desa dari yang tertinggi hingga terendah adalah Medan Mas (Rp 95.354.976/ha/tahun), Nipah Panjang (Rp 76.645.333/ha/tahun) dan Batu Ampar (Rp 68.195.913/ha/tahun). Kondisi ekosistem mangrove di kawasan Batu Ampar berdasarkan persentase luas mangrove terhadap luas desa, persentase kelas kerapatan tinggi dan ketebalan mangrove di masing-masing desa dari yang terbaik adalah Desa Batu Ampar 58,2%; 93,8%; 42.271 m, Desa Nipah Panjang 6.4%; 98,6%; 24.088 juta dan Medan Mas 4,5%; 80,2%; 7.236 m. Persepsi masyarakat tentang ekosistem dan ekowisata mangrove di kawasan mangrove Batu Ampar berbeda nyata antar desa. Secara berurutan, persepsi tertinggi hingga terendah adalah Nipah Panjang (3,7), Medan Mas (3,6) dan Batu Ampar (3,5). Kondisi mangrove yang baik tidak selalu berkontribusi positif dalam membentuk persepsi masyarakat yang tinggi dan meningkatkan valuasi ekonomi di Desa Batu Ampar. Namun demikian, persepsi masyarakat yang tinggi dapat membentuk valuasi ekonomi yang tinggi dan menjamin kondisi ekosistem mangrove di Desa Nipah Panjang. Selain itu, valuasi ekonomi yang tinggi tidak selalu memberikan kontribusi positif bagi ekosistem mangrove dan persepsi masyarakat di Desa Medan Mas.

“…Changes in land use which also contributed to the destruction of mangrove ecosystems were triggered by rapid reclamation, an increase in coconut plantations and settlements since the 1950s, followed by extensive shrimp pond expansion in the early 1980s (Akbar et al 2017). Damage to the mangrove ecosystem plays a role in changing the coastline to reverse (Ritohardoyo et al 2017).…”

Abstract. Dinilhuda A, Akbar AA, Jumiati, Herawati H. 2020. Potential of mangrove ecosystem as carbon storage for global warming mitigation. Biodiversitas 21: 5353-5362. The mangrove ecosystem in Karimunting Bay of West Kalimantan, Indonesia is one of the conservation areas with an area of 138.2 ha. Vegetation making up of that mangrove ecosystem is dominated by Avicennia marina. The existence of mangroves has a role in carbon storage. The ability to store carbon in mangrove forest ecosystems is four times greater than in other tropical forests around the world. Mangrove stems have the greatest ability in storing carbon by up to 55.52%. The research objective was to analyze the potential for carbon storage in the fringe mangrove ecosystem which was dominated by A. marina. This research method is based on a survey of vegetation density in the field. The survey was carried out in Karimunting Bay in three parts of the bay, north, central, and south. Each part of the bay consists of two locations, namely at the front of the breakwater towards the sea and behind the breakwater towards the land. Each location consisted of a plot of 10 x 10 with five replications. The vegetation parameters measured are the types of growth forms, the mangrove ecosystem species, and the diameter and height of the trees, as well as environmental parameters (pH, temperature, and salinity). Destructive method was used on A. marina stems for estimating analysis of mangrove carbon storage in the laboratory. A. marina stem samples were used to test the carbon content with LOI (Lost on Ignition) analysis. Analysis of changes in mangrove area is based on the 2009 and 2019 landscape images. The results show that the mangrove ecosystem of Karimunting Bay has a total density of 177,480 individuals/ha. The amount of carbon storage reached 99,231 mg/ha in 2019 and predictions of total carbon storage over the last 10 years are as much as 13,717,951 tons. Deposits of carbon in fringe mangrove illustrate the carbon dioxide absorption potential of 36,390,608 tons of CO2. The amount of CO2 absorption in fringe mangrove ecosystem type plays a role in reducing greenhouse gas (GHG) emissions with a conditional target according to the Nationally Determined Contribution (NDC) in 2030 of 834 million tons of CO2 to prevent temperature increases.

“…Therefore, the government is responsible for the management based on the benefits and sustainability, democracy, justice, solidarity, openness and integrity. Ritohardoyo et al, (2017) pointed out that the emergence of development in coastal regions can result in erosion and mangrove ecosystems damage. This disaster can destroy settlements, agricultural land, and public infrastructures.…”

Abstract:The occurrence of pollution in mangrove land is due to changes in physical, chemical and biological properties of water because of the increasing human activities that produce problems due to residential and industrial wastes and other related activities, or due to seawater tide. The existence and presence of residential and industrial wastes in soil sediments can disturb the environment that in turn will threaten mangroves growth. This study was aimed to reveal the presence of heavy metals in sediment shown by environmental changes of water polluted by residential and industrial wastes. The study was conducted in field plots located at five watershed areas of Andil, Porangan, Kacar, Gombal and Krondo in Tambak Lekok Village of Pasuruan District, East Java. Field exploration and observation was started from waterfront and riverside vegetations. The exploration was made 300 m toward inland, perpendicular to the edge of the waters. The sediment samples of mangrove stands were collected at three points for each plot. The thickness of the collected sediment samples was ± 10 cm from the surface. Sediment samples were analyzed for heavy metals (Pb, Cr, Zn and Cu) and texture. The results showed that the Pb severely polluted the Gombal watershed with a concentration of 7.24mg/kg. The lowest Pb concentration of 7.24 mg/kg was observed for Andil watershed. Except for Andil watershed, Cu heavily polluted all the watersheds studied.
