Mangroves are one of the ecosystems that play an essential role in mitigating climate change by storing and absorbing CO2. One of the mangrove areas that can be found in Jepara Regency in Teluk Awur and Tanggul Tlare. Both of these areas is experiencing coastal abrasion, which impacts the land and mangrove areas. The reduced area of mangroves affects the ability of the ecosystem to store and absorb CO2. This study intends to determine the potential for CO2 absorption in above-ground, below-ground, and mangrove sediments. The method used in determining the station point is the purposive sampling method. While the analysis of the calculation of standing carbon storage uses allometric equations in sediments using the LOI method (Loss on Ignition). The potential for carbon absorption above-ground station 1 is 75.12 Ton.ha-1, below-ground is 51.48 Ton.ha-1, and sediment is 286.49 Ton.ha-1. While the potential for CO2 absorption at station 2 consists of 28.27 Ton.ha-1 above ground, 19.86 Ton.ha-1 underground, and 243.73 Ton.ha-1 of sediment. Based on the study’s results, the potential for CO2 absorption in the mangrove area in Teluk Awur can store more carbon than in the Tanggul Tlare mangrove area, this is supported by the diameter of the mangrove stems in Teluk Awur which has a higher size.

“…Berdasarkan hasil analisis kemerataan pada Tabel 4 bahwa pada areal bekas tebangan hutan mangrove tahun 2016 pada tingkat semai yaitu 0.72 dan pancang 0,90 serta tingkat semai 0,73 pada blok tebang tahun 2017 yang menunjukkan komunitasnya semakian merata. Nilai indeks kemerataan tinggi menunjukkan keberadaan setiap jenis mangrove dalam kondisi merata (Farista & Virgota 2021). Hasil ini ada persamaan dengan penelitian yang dilakukan oleh Selfiani ( 2018 Saran dari hasil analisis vegetasi hutan mangrove pada tiga blok tebangan, untuk melakukan pembinaan areal bekas tebangan, terutama blok tebang tahun 2018 dengan melakukan pengkayaan jenis sehingga di lokasi tersebut tidak hanya ditumbuhi hanya jenis vegetasi mangrove.…”

PT. BIOS Batu Ampar is one of the private companies in Kubu Raya Regency that utilizes mangrove forests by implementing a seed tree silviculture system so that later the area can still maintain its sustainability. The purpose of the study was to determine the number of species and the diversity and dominance of mangrove forest vegetation types in block logging in 2016, 2017 and 2018. The study used a survey method with a sampling technique in a line with a tide. On each observation plot, data collection of types of seedlings, stakes, and trees was carried out. The data obtained are then analyzed by the Diversity Index, Dominance Index and Evenness Index. The results showed that the seedling-level type diversity index in the three cutting years was 0.000- 1.250, and the stake rate was 0.000-1.073. The Dominance Index of the seedling level in all three cutting years is 0.415-1.000, and the stake rate is 0.316-1.000. Keme Index of the seedling level in all three cutting years is 0.000-0.773, and the stake rate is 0.000-0.902.Keywords: diversity, dominance, evenness, Mangrove Forest. Abstrak PT. BIOS Batu Ampar adalah salah satu perusahaan swasta di Kabupaten Kubu Raya yang memanfaatkan hutan mangrove dengan penerapan sistem silvikultur pohon induk (Seed Tree Method) agar nantinya kawasan tersebut tetap dapat mempertahankan kelestariannya. Tujuan penelitian adalah untuk menentukan jumlah spesies dan keanekaragaman serta dominasi jenis vegetasi hutan mangrove pada penebangan blok pada tahun 2016, 2017 dan 2018. Penelitian menggunakan metode survei dengan teknik pengambilan sampel secara garis berpetak. Pada setiap plot pengamatan dilakukan pengumpulan data jenis semai, pancang, dan pohon. Data yang deperoleh kemudian di analisis Indeks Keanekaragaman, Indeks Dominasi dan Indeks Kemerataan. Hasil penelitian menunjukkan bahwa indeks keanekaragaman jenis tingkat semai pada ketiga tahun tebang adalah 0,000- 1,250, dan tingkat pancang adalah 0,000-1,073. Indeks Dominasi tingkat semai pada ketiga tahun tebang adalah 0,415-1,000, dan tingkat pancang adalah 0,316-1,000. Indeks Kemerataan tingkat semai pada ketiga tahun tebang adalah 0,000-0,773, dan tingkat pancang adalah 0,000-0,902.Kata Kunci: Keanekaragaman, dominasi, kemerataan, Hutan mangrove

“…In general, mangroves can grow in four zones: the open zone, the middle zone, the zone that has rivers of brackish to almost fresh water, and the land border zone, which has fresh water. Differences in the formation of mangrove zoning are caused by tides and currents that carry sediment and substrate (Farista & Virgota, 2021).…”

As a type of coastal vegetation, mangroves are valuable, unique, and vulnerable. Mangrove ecosystems have a distinctive vegetation structure, which consists of several characteristics sequentially, such as trees, saplings, poles, and seedlings. This study aims to assess and monitor the structure and composition of mangrove vegetation in Makassar City, South Sulawesi. Field surveys were conducted to measure and monitor mangroves in two different areas, namely coastal areas and small islands. The highest mangrove density is at Station 2, which is 0.59 ind/m 2 , which is a river area. The station with the lowest density is at Station 1, which has a value of 0.23 ind/m 2 , which is a coastal area. Avicennia marina, Rhizophora apiculata and Acanthus ilicifolius were found to have the highest importance value index. Location 1 is the least stable because it only has the Avicennia marina mangrove species. Meanwhile, at location 3 (Lakkang Island, a small island), there are variations in the value of each index, although it is still in the low category. This means that in general, each research location has a less stable ecosystem. Furthermore, this study can contribute to conservation, biodiversity assessment, and sustainable mangrove ecosystem management strategies.
