The exploitation of the Malili Lake Complex in South Sulawesi as a natural resource that is not accompanied by wisdom has caused various major problems, such as damage to natural resources, loss of resources and the emergence of various wastes, which result in a decrease in the quality of the environment.The objectives of this research are: to examine in depth the dynamics of the quality of the aquatic environment and the influencing factors. Testing of environmental parameters measured in the field using a tool, namely the Water Quality Checker. Parameter measurements carried out in the field during June-August 2021 by taking six observation stations, namely: Salonsa Beach, Dream Beach, Malili River, Karebbe River, Sorowako Pier and Timampu Pier. The condition of the waters in has been polluted by the presence of domestic and industrial waste and the activities of the people who live in the vicinity.

Seagrass ecosystem is one of the coastal ecosystems that can absorb carbon and subsequently store it at a high capacity. This research aimed to study carbon stocks in biomass based on seagrass type and density, differences in carbon stocks between below-ground and above-ground, and the potential for carbon storage of the seagrass ecosystem on the coast of Waai and Liang, Ambon Island. Five seagrass species species were found, including Enhalus acoroides, Halophila ovalis, Halodule pinifolia, Thalassia hemprichii and Cymodocea rotundata,. Based on the results, halassia hemprichii was predominant in Liang waters and Halodule pinifolia was predominant in Waai waters. The highest seagrass biomass in both the below ground and above ground was found for Cymodocea rotundata in Waai waters and Thalassia hemprichii in Liang waters. The total carbon stock in Liang waters was 39.75 gC/m2, whereas that in Waai waters was 56.46 gC/m2. The results showed that the total carbon stock below ground was much greater than above ground, suggesting that more carbon is stored below seagrass substrate than above it in both Waai and Liang coastal waters.

“…Hasil penelitian ini didapatkan berdasarkan hasil monitoring padang lamun di Kalimantan dengan jenis yang dominan adalah Thalassia hemprichii dan Enhalus acoroides (Balai Pengelolaan Sumber Daya Pesisir dan Laut, 2021). Faktor pembatas yang mempengaruhi pertumbuhan lamun ialah suhu, cahaya, salinitas, kedalaman, substrat dasar, nutrient serta pegerakan muka air laut (Rugebregt et al, 2020). Lamun di pesisir Kalimantan Barat tumbuh di lingkungan dengan suhu 30.5 o C dengan salinitas 32 0 /00, kedalaman 0,5-1 meter, pH 8.5, dan arus 0,2-0,4 m/s dengan jenis substrat pasir-berlumpur dalam kategori rusak/miskin (Gusmalawati et al, 2018;Octavina et al, 2020).…”

Potensi karbon biru (blue carbon) di pesisir Kalimantan Barat terdapat pada ekosistem mangrove, padang lamun, dan terumbu karang. Ketiga ekosistem ini tersebar di Kabupaten Sambas, Bengkayang, Mempawah, Kubu Raya, Ketapang dan Kota Singkawang. Penelitian ini bertujuan mengetahui luas dan keanekaragaman jenis ekosistem pesisir terkait dengan potensi karbon biru. Metode non-destruktif digunakan untuk mengkaji kemampuan ekosistem pesisir dalam menyerap karbon. Mangrove didominasi jenis didominasi oleh Rhizophora spp., Avicennia spp. Bruguiera spp., Sonneratia alba, Excoeacaria agallocha, dan Nypa fruticans. Padang lamun didominasi jenis Thalassia hemprichii dan Enhalus acoroides, sementara terumbu karang didominasi jenis Porites spp. dan Montipora spp. Estimasi serapan karbon terbesar berada di Kubu Raya sebesar 0,026 PgC (0,095 PgCO2e) dan yang terkecil berada di Kota Singkawang sebesar 0,000032 PgC (0,00012 PgCO2e). Penelitian ini mengungkap bahwa kemampuan serapan karbon berbanding lurus dengan luas ekosistem pesisir. Ekosistem mangrove merupakan ekosistem yang memiliki kemampuan dalam menyerap karbon, daripada ekosistem lamun dan terumbu karang. Upaya antropegenik memperparah degradasi ekosistem di pesisir Kalimantan Barat. The potency of blue carbon in the West Kalimantan is found in mangroves, seagrass beds, and coral reefs ecosystem. Sambas, Bengkayang, Mempawah, Kubu Raya, Ketapang, and Singkawang regencies coastal had a big potential blue carbon. This study aims to estimate the potential of blue carbon on coastal ecosystems diversity. This research was applying a non-destructive method to quantify the carbon sequestration of the ecosystems. Rhizophora spp., Avicennia spp, dominates mangrove, in Kalimantan Barat. Bruguiera spp., Sonneratia alba, Excoeacaria agallocha, dan Nypa fruticans, for mangroves, Thalassia hemprichii and Enhalus acoroides for seagrass and Porites spp. and Montipora spp, for coral reefs. The most extensive estimated carbon sequestration is in Kubu Raya regency with 0.026 PgC (0.095 PgCO2e), and the smallest one is in the Singkawang regency with 0.000032 PgC/ha (0.00012 PgCO2e/ha). Based on this research, it is observed that the ability of carbon sequestration is directly influenced by the coverage area of the coastal ecosystem, especially the mangrove forest which are dynamic due to anthropogenic activities.
