mangrove serta pengaruh aktivitas masyarakat terhadap ekosistem mangrove di
Kampung Nipah Desa Sei Nagalawan. Penelitian ini dilakukan pada bulan Januari
- April 2017. Penelitian ini dilakukan dengan metode survei dan pengambilan
sampel dilakukan dengan metode Purposive Sampling. Hasil penelitian
menunjukkan bahwa kondisi mangrove di Kampung Nipah Desa Sei Nagalawan
tergolong jarang (rusak).Kondisi ekologi perairan di setiap stasiun(suhu, salinitas
dan pH) masih memenuhi baku mutu menurut Kepmen LH No. 51 Tahun 2004
kecuali DO yaitu sebesar 3,2-4 mg/L. Total Nilai Skoring yang diperoleh dari
kuisioner aktivitas masyarakat yaitu sebesar 200. Nilai tersebut berarti bahwa

faktor aktivitas masyarakat berpengaruh terhadap kerusakan ekosistem mangrove
di kawasan Kampung Nipah Desa Sei Nagalawan.
