Keberadaan ekosistem mangrove di Kawasan Pesisir Tanjungpiayu memiliki potensi untuk dimanfaatkan sebagai kawasan hijau. Meskipun kondisi ekosistem mangrove di Tanjungpiayu secara umum masih baik, beberapa area telah mengalami penurunan kualitas. Tujuan penelitian ini untuk mengetahui indeks ekologi ekosistem mangrove di Kawasan Pesisir Tanjungpiayu. Data penelitian dikumpulkan menggunakan metode survei dengan stasiun pengamatan yang dipilih secara purposive sampling dan pengukuran data dilakukan dengan metode transek kuadrat 10x10m. Analisis data meliputi indeks nilai penting, indeks keseragaman, indeks keanekaragaman serta indeks dominansi. Dari empat stasiun pengamatan, ditemukan dua jenis mangrove yaitu Rhizophora mucronata dan Rhizophora apiculata, dengan nilai indeks penting tertinggi di stasiun 3 (INP 300%). Nilai dari indeks ekologi ekosistem mangrove dari empat stasiun penelitian menunjukkan indeks keanekaragaman berkisar antara 0 – 0,45 (kategori rendah), indeks keseragaman berkisar antara 0 – 0,65 (kategori rendah – sedang), dan indeks dominansi berkisar antara 0,73 – 1 (kategori sedang – tinggi). Nilai Indeks keanekaragaman paling rendah ditemukan pada stasiun 3 yang hanya ditemukan satu jenis mangrove saja.

Penelitian ini dilakukan dari September 2023 hingga Mei 2024 di kawasan hutan mangrove pesisir Tanjungpiayu Kota Batam. Tujuan dari penelitian ini adalah untuk menganalisis potensi biomassa, stok karbon, dan serapan karbon di kawasan hutan mangrove Tanjungpiayu, menghitung nilai ekonomi karbon hutan mangrove Tanjungpiayu, serta untuk merumuskan pengelolaan ekosistem mangrove dalam upaya adaptasi perubahan iklim di pesisir Tanjungpiayu Kota Batam. Lokasi penelitian ditentukan melalui metode survei, dimana titik sampling dipilih secara purposive sampling. Untuk menghitung biomassa pohon dilakukan tanpa merusak (nondestructive), dengan mengukur diameter batang setinggi dada (Diameter at Breast Height/DBH) yang diambil pada ketinggian sekitar 1,3 m dari permukaan tanah. Selanjutnya, perhitungan dilakukan dengan model allometrik untuk menghitung potensi biomassa dan penyimpanan karbonnya. Penentuan strategi pengelolaan menggunakan metode AHP dengan responden sejumlah 7 orang sebagai informan kunci. Berdasarkan hasil analisis data nilai total biomassa, stok karbon dan serapan CO2 pada lokasi penelitian adalah sebesar 150,32 ton/ha, 70,65 ton/ha dan 259,06 tonC/ha. Hal ini menunjukkan bahwa mangrove Tanjungpiayu memiliki potensi sebagai penyerap karbon atmosfer. Berdasarkan perhitungan nilai ekonomi karbon mangrove di pesisir Tanjungpiayu adalah Rp 25.054.254,16 (pasar sukarela) dan Rp 65.475.117,55 (CDM). Berdasarkan perolehan skor tertinggi aspek saintek menjadi prioritas dalam mempertimbangkan alternatif strategi pengelolaan ekosistem mangrove. Alternatif prioritas dengan skor tertinggi untuk pengelolaan ekosistem mangrove di pesisir Tanjungpiayu berupa pendampingan peningkatan keterampilan masyarakat dalam pengelolaan ekosistem mangrove berbasis adaptasi perubahan iklim.

Ekosistem mangrove penting bagi wilayah kepulauan untuk melindungi pantai dari bahaya gelombang tinggi yang mengakibatkan banjir dan erosi pantai. Namun, mangrove hanya dapat tumbuh pada kondisi sesuai kriteria ekologi ekosistem mangrove. Pelestarian ekosistem mangrove perlu diintegrasikan kedalam perencanaan tata ruang kota pesisir. Menyusun rencana tata ruang kota pesisir di pulau kecil harus adaptif terhadap perubahan lingkungan dengan berbasis pada ekologi ekosistem pesisir. Penelitian ini bertujuan untuk membandingkan hasil analisis kesesuaian habitat mangrove dengan rencana pola ruang RDTR Kota Tanjungpinang. Kesesuaian habitat ekosistem mangrove di Kota Tanjungpinang berdasarkan kriteria ekologi mangrove diperoleh luas lahan yang sangat sesuai yaitu seluas 1227,87 Ha, sesuai 2651,52 Ha, dan kriteria cukup sesuai dengan luas 412,84 Ha. Zona budidaya antara lain berupa zona perumahan, perdagangan jasa, perkantoran, industri pada rencana peruntukan ruang RDTR Kota Tanjungpinang berada pada lahan yang memiliki kesesuaian habitat ekosistem mangrove berdasarkan kriteria ekologi.

Research has been conducted on the prevention strategy of fishing vessel waste pollution carried out in April 2024 with the location at Tarempa Coastal Fishing Port. This research aims to formulate a plan for preventing fishing vessel waste at Tarempa Coastal Fishing Port. This research used a survey method with a purposive sampling technique. The data taken in this study are the type and amount of waste from ship activities during mooring, ship maintenance and repair, and maintenance and repair of fishing gear at the Tarempa PPP. The results of observations in the field found that the management done before was only in the form of burning, disposing of garbage in trash cans, hoarding garbage, and some throwing garbage into the sea. Based on the results of the analysis of waste prevention strategies, ten management alternatives were found, including port management needs to establish partnerships with crew members and the community to prevent waste generation at PPP Tarempa, apply rewards for crew members who manage waste well, improve cleaning and waste management facilities at PPP Tarempa, increase routine supervision to prevent waste generation at PPP Tarempa, apply punishment for crew members who pollute the environment, provide counseling and K3 training for crew members at PPP Tarempa, optimize the function of cleaning and waste management facilities at PPP Tarempa.

The process of litter decomposition plays an important role in producing important nutrients in the food chain and aquatic productivity of mangrove ecosystems. The purpose of this study is to determine the production of mangrove litter and its decomposition based on the density and cover of the mangrove canopy. The research location is in the waters of Bulang village. This research was carried out from June to July 2024. The method used is a systematic random method carried out in 20 sampling points. The research results found five species of mangroves, namely Rhizophora apiculata, Bruguiera cylindrica, Bruguiera gymnorrizha, Lumnitzera littorea, and Scyphiphora hydrophyllacea. The production of mangrove litter was 11.46 g DW/m² and the highest mangrove decomposition was 55.30%. The overall average density was 1195 individual/ha with medium criteria and the overall average canopy cover was 60.03% with moderate criteria. The results of the correlation test between litter production and canopy density and cover showed a very strong and significant correlation with litter production.
