TRI SUCI RN. Analisis kerusakan dan rekomendasi rehabilitasi mangrove di Pulau Pari, Kepulauan Seribu, DKI Jakarta. Dibimbing oleh ALI MASHAR dan HEFNI EFFENDI. Ekosistem mangrove memegang peranan penting dalam menjaga keseimbangan ekosistem pesisir, namun sangat rentan terhadap tekanan aktivitas manusia. Penelitian ini bertujuan untuk menganalisis tingkat kerusakan serta merumuskan rekomendasi rehabilitasi mangrove di Pulau Pari, Kepulauan Seribu, DKI Jakarta. Penelitian dilakukan pada bulan November–Desember 2023 di dua stasiun pengamatan yang mewakili kawasan konservasi dan kawasan pariwisata. Hasil penelitian menunjukkan bahwa kerapatan mangrove tertinggi terdapat pada Stasiun 1 sebesar 1.358,33 pohon/ha, sedangkan Stasiun 2 hanya 491,67 pohon/ha. Nilai indeks kesehatan mangrove (IKM) di Stasiun 1 sebesar 1,75 (kategori sedang), dan Stasiun 2 sebesar 1,25 (kategori buruk). Indeks kualitas lingkungan (Qe) di kedua stasiun tergolong tinggi, yaitu 76,18% dan 71,90%. Berdasarkan matriks rehabilitasi, kedua stasiun direkomendasikan untuk dilakukan replantasi guna meningkatkan tutupan vegetasi dan keragaman spesies. Hasil ini menunjukkan bahwa meskipun kondisi lingkungan masih mendukung, ekosistem mangrove di Pulau Pari memerlukan upaya rehabilitasi aktif agar fungsi ekologisnya dapat pulih secara optimal.

TRI SUCI RN. Analysis of Mangrove Damage and Rehabilitation Measures in Pari Island, Seribu Islands, DKI Jakarta. Supervised by ALI MASHAR and HEFNI EFFENDI. Mangrove ecosystems play an essential role in maintaining coastal ecological balance but are highly vulnerable to human pressures. This study aims to analyze the level of mangrove damage and propose rehabilitation measures on Pari Island, Seribu Islands, DKI Jakarta. The research was conducted from November to December 2023 at two observation stations representing conservation and tourism areas. Results showed that mangrove density at Station 1 reached 1,358.33 trees/ha, while Station 2 had 491.67 trees/ha. The Mangrove Health Index (MHI) at Station 1 was 1.75 (moderate category), and at Station 2 was 1.25 (poor category). The Environmental Quality Index (EQI) was high at both stations, 76.18% and 71.90%, respectively. Based on the rehabilitation matrix, both stations are recommended for replantation to increase vegetation cover and species diversity. Although the environmental conditions remain supportive, active rehabilitation is required to restore the ecological function of mangroves in Pari Island optimally.
