Abstract

The coral reef ecosystem has been continuously degraded in various parts of Indonesia, including the Anambas Islands. This research aimed to discover the content of Potassium Cyanide (KCN) accumulated on corals and the effect on indicator fishes abundance in the Anambas Islands. This research was conducted at 25 observation stations in the Anambas Islands National Marine Protected Area. The potassium cyanide (KCN) content was tested with the principle of titration and distillation. The coral samples used ranged from 10-20 g diluted in 100-200 ml distilled water. The method used to determine the abundance of indicator fish was underwater visual census or UVC, which recorded fish in every station. This research recorded 307 fish individuals from 14 species of the Chaetodontidae family. Potassium Cyanide's content on corals was high ranging from 0,009-0,032 mg/L with an average 0,0205 mg/L. We concluded that there was a negative correlation between the content of Potassium Cyanide (KCN) on corals and indicator fishes abundance, which means the higher the Potassium Cyanide content (KCN) is on corals, the lower the indicator fishes abundance will point out.

Abstract

Mangrove ecosystems are important coastal ecosystems that provide a variety of functions. Mangrove ecosystems provide a variety of environmental services including absorbing carbon and contributing to climate change mitigation, protecting coastal areas from storms, tsunamis, and erosion. In addition to providing a variety of environmental services, these ecosystems are also habitats for a variety of living organisms, both aquatic and terrestrial, resident and migrant, also nationally and internationally protected species. The benefits provided by mangrove are contrast to the rate of degradation, which has the potential for loss of wildlife habitat and a decrease in biodiversity value, especially mammals. This study was conducted to analyse the value of biodiversity, especially mammals in the Mangrove Ecotourism Area, Pesawaran Regency. This study uses the method of line transects, mist nets, and sound identification. The results of the study recorded 6 species of mammals with a species diversity value (H') of 1.46, richness of 1.60, evenness of 0.72, and species dominance of 0.30. Mammal species diversity inside the ecotourism area is higher than outside the area. Protected mammals are not found in the area.

Abstract

Climate change and global warming continue to occur up to the present. One of the gases significantly influencing climate change is carbon dioxide (CO2). The increase in CO2 can be mitigated by capturing carbon from the atmosphere and storing it in biomass in a process known as carbon sequestration. Forests play a crucial role as a mitigator in reducing global warming and climate change, acting as both a carbon sink and absorber. Mangrove forests, in particular have a high capacity for carbon storage, approximately three times more than terrestrial forests. This research aims to (1) assess the health condition of the mangrove forests in Pesawaran Regency and (2) estimate the CO2 absorption produced by Pesawaran Regency. The study utilizes Sentinel-2 satellite imagery and field data collection. Sentinel-2 images undergo Normalized Difference Vegetation Index (NDVI) transformation. The research results indicate that the mangrove forests in Pesawaran Regency in 2023 are predominantly in good condition, covering an area of 562,31 hectares (99%), while 6,12 hectares (1%) are in a degraded condition. The CO2 absorption by the mangrove forests pesawaran regency is estimated to be 336.367,47 tons CO2  and 591,75 tons CO2/ha.

Abstract

Data spasial dapat diproses menggunakan berbagai teknikkinterpolasi, namun setiap teknik akan menghasilkannoutput yang berbeda. Pemilihan metodeeyang digunakan akan berdampak pada hasil akhir yang diperoleh. Klorofil-a berperan penting dalam menentukan tingkat produktivitas primer di perairan (Susilo, 2000). Kesuburan suatu perairan dapat diukur melalui tingkat produktivitas primer yang dihasilkan. Penelitian ini dilaksanakan di Kabupaten Kayong Utara menggunakan data klorofil-a dari citra Aqua Modis. Penelitian ini bertujuan untuk membandingkan teknik Interpolasi IDW & Kriginggguna menentukan teknik yang paling mendekati nilai klorofil-a yang sebenarnya, serta untuk mengidentifikasi tingkat kesuburan perairan laut di wilayah tersebut berdasarkan konsentrasi klorofil-a. Data citra Aqua Modis diolah menggunakan perangkat lunak SeaDAS dan diinterpolasi menggunakan ArcGIS. Berdasarkan uji akurasi dengan RMSE, metode Kriging menunjukkan hasil yang lebih akurat dibandingkan metode IDW, dengan nilai RMSE masing-masing sebesar 3,889607 dan 3,900089. Konsentrasi klorofil-a terendah pada kedua metode tercatat sebesar 0,32 mg/m3, sedangkan yang tertinggi mencapai 83,22 mg/m3, dengan nilai rata-rata 4,08 mg/m3. Distribusi klorofil-a di perairan Kayong Utara menunjukkan konsentrasi tertinggi di wilayah pesisir yang semakin menurun ke arah laut lepas. Distribusi bulanan mengindikasikan bahwa konsentrasiinilai klorofil-a mencapai puncaknya tertinggi pada bulan September, dengan nilai 8,16 mg/m³, sementara konsentrasi terendah tercatat pada bulan Oktober, yaitu sebesar 2,04 mg/m³.

Abstract

Ekosistem lamun di kawasan pesisir saat ini banyak memperoleh ancaman dan tekanan dari kegiatan antropogenik. Perairan Teluk Lampung memiliki luas padang lamun sebesar 710 Ha pada tahun 2015. Dengan kondisi baik sebesar 64,79%, kondisi sedang sebesar 22,59% dan kondisi rusak sebesar 12,62 %. Lokasi kajian merupakan kawasan ekosistem lamun yang mendapat pengaruh langsung dari aktifitas budidaya keramba jaring apung, daerah penangkapan ikan dan kerang, kegiatan ekowisata mangrove dan daerah aliran sungai Desa Sidodadi. Penelitian ini bertujuan untuk mengetahui kondisi eksisting dan status ekosistem padang lamun kawasan perairan Ekowisata Mangrove Cuku Nyinyi. Metode sampling yang digunakan berdasarkan panduan monitoring padang lamun oleh LIPI dengan menggunakan kuadran 50x50 cm. Hasil penelitian menunjukkan bahwa kondisi kualitas perairan di lokasi kajian cukup sesuai untuk kelangsungan hidup dan perkembangan lamun. Berdasarkan hasil penelitian diperoleh dua jenis lamun yaitu Enhalus acoroides dan Thalassia hemprichii. Jenis E. acoroides memiliki rata-rata kerapatan sebesar 339 individu dan jenis T. hemprichii sebesar 104 individu. Persentase penutupan lamun tergolong dalam kategori sedang dengan dominansi jenis tertinggi pada E. acoroides. Berdasarkan nilai penutupan lamun dapat disimpulkan bahwa status padang lamun kawasan Ekowisata Cuku Nyinyi termasuk dalam kategori kurang kaya atau dalam kondisi kurang sehat.

Abstract

Mangrove are important coastal ecosystems that provide a variety of ecosystem services and ecological functions. These ecosystem services include natural barriers that protect coastal areas from cyclones, tsunamis, and erosion. Habitats for breeding, foraging, and nursery for various species of aquatic and tereterial species. The benefits provided by mangrove are contrast to the rate of degradation. Various parties have a responsibility to contribute to efforts to maintain a sustainable environment. Biodiversity has been globally recognised as one of the determining factors for the sustainability of an ecosystem. The study aims to assess the diversity of herpetofauna species in the Cukunyinyi Mangrove ecotourism area as an instrument of environmental monitoring. The method in this study was the Visual Encounter Survey (VES). The diversity of herpetofauna (H') observed in the area was 1.06 inside the Ecotourism Area and 0.56 outside the ecotourism area. The indices of species richness (Dmg) in each area were 1.24 and 0.72. The two regions have evenly distributed with an evenness value of more than 80%. No species protected under national regulation, two species whose trade was restricted internationally and included in the CITES Appendix II.
