Pantai Labu merupakan daerah yang terletak di Kabupaten Deli Serdang dan dimanfaatkan oleh masyarakat untuk penangkapan ikan menggunakan kapal, pemukiman serta aktivitas wisata. Adanya aktivitas tersebut diduga menyebabkan penurunan kualitas lingkungan mangrove yang berada di Pantai Labu. Nitrat dan Fosfat merupakan nutrien utama yang menentukan kestabilan pertumbuhan vegetasi mangrove. Akibat penurunan kualitas lingkungan, maka akan mempengaruhi distribusi nitrat dan fosfat yang dapat mempengaruhi pertumbuhan mangrove tersebut. Penelitian ini bertujuan untuk mengetahui kandungan nitrat dan fosfat di substrat mangrove serta keterkaitannya dengan kerapatan mangrove. Penelitian ini dilakukan pada bulan September-Oktober 2019 dengan menggunakan metode purposive sampling pada 5 titik stasiun. Hasil penelitian didapatkan nilai total kerapatan mangrove untuk tingkat pohon yaitu 2,89 Ind/m2,untuk tingkat pancang 1,75 Ind/m2 dan untuk tingkat semai 0,1 Ind/m2. Kandungan nitrat dalam sedimen berkisar antara 0,7-1,11 mg/kg dan kandungan fosfat dalam sedimen berkisar antara 2,5-2,8 mg/kg. Kandungan nitrat di subtrat yang didapatkan dalam penelitian ini termasuk ke dalam kategori rendah. Kandungan fosfat di subtrat yang didapatkan dalam penelitian ini termasuk ke dalam kategori rendah. Keterkaitan nitrat dengan kerapatan mangrove yang didapatkan sebesar 98% yang berarti nitrat memiliki pengaruh yang sangat besar dengan kerapatan mangrove, sedangkan keterkaitan fosfat dengan kerapatan mangrove yang didapatkan adalah sebesar 20% yang berarti fosfat memiliki pengaruh yang kecil (sedikit) dengan kerapatan mangrove.Pantai Labu is an area located in Deli Serdang Regency which is used by the people for fishing using ships, settlements and tourist activities. The existence of these activities is thought to cause a decrease in the quality of the mangrove environment on Pantai Labu. Nitrate and Phosphate are the main nutrients that determine the stability of mangrove vegetation growth. As a result of environmental degradation, it will affect the distribution of nitrates and phosphates which can affect the growth of mangroves. This study aims to figure out the nitrate and phosphate content in the mangrove substrate and its relation to the density of the mangrove. This research was conducted in September-October 2019 using a purposive sampling method at 5 station points. The results obtained total value of mangrove density for tree level is 2.89 Ind/m2, for the sapling level 1.75 Ind/m2 and for seedling level 0.1 Ind/m2. Nitrate content in sediments ranged from 0.7-1.11 mg/kg and phosphate content in sediments ranged from 2.5-2.8 mg/kg. The nitrate and phosphate content in the substrate obtained in this study was the low category. Result of statistical analysis of the relationship between nitrate and mangrove density was 98%, which means that nitrate had a very big effect on mangrove density, while the relationship between phosphate and mangrove density was 20%, which meant that phosphate had a small effect (a little) with mangrove density.

Sembilan Island was one of the 17 islands located in the East Coast of North Sumatra. This island is surrounded by mangrove with varying thickness and density. Information on the identification and potential of mangrove in this island already reported but limited to a narrow area. Information about the value and status of mangrove ecology in this island have not been written, so it was needed to carry out for a study of mangrove ecological analysis. This information could be used later as a reference in sustainable mangrove management. The objective of the study was to determine the value and ecological status of mangroves. The research was conducted in September 2015. The data were collected at 9 sampling points namely; 4 points in the east, 2 points in the south and 3 points in the west part of the study areas. The spot check method was used in the study. The results showed that there were 28 species of mangrove belonging to 13 families. It's divided into 26 species of true mangrove and two species of associated mangroves. Mangrove’s zonation was Avicennia/Sonneratia on the front and ferns (A. Aureum and A. speciosum) in the section near the mainland. Mangrove thickness reached 134 - 1683 m. The density of mangrove was 333 - 4601 individuals/ha with the cover area of 2522 - 5810 cm2/ha. The results of the importance index value of mangrove showed that A. marina has a great influence and role in the community of mangrove vegetation, especially in the eastern part. Therefore, the mangrove in Sembilan Island was categorized into damage to good condition. The good category was recorded in the western part of the island, while the damaged category was found in the east part of the island.Pulau Sembilan merupakan satu diantara 17 pulau yang terdapat di wilayah Pantai Timur Sumatera Utara. Hampir sepanjang pantai di Pulau Sembilan di tumbuhi oleh mangrove dengan ketebalan yang bervariasi. Informasi tentang identifikasi dan potensi mangrove di Pulau Sembilan sudah ada dilaporkan, namun terbatas pada areal yang sempit. Informasi tentang nilai dan status ekologi mangrove di Pulau Sembilan belum dilaporkan, sehingga perlu adanya kajian tentang analisis ekologi mangrove. Informasi ini nantinya dapat dijadikan sebagai acuan dalam pengelolaan mangrove yang berkelanjutan. Penelitian ini bertujuan untuk mengetahui nilai dan status ekologis mangrove di Pulau Sembilan. Lokasi penelitian dibagi menjadi tiga area dengan 9 titik pengamatan yaitu timur 4 titik, selatan 2 titik, dan barat 3 titik. Penelitian dilaksanakan pada September 2015. Pengambilan contoh mangrove, dilakukan dengan menggunakan metode spot check. Hasil penelitian didapatkan bahwa jenis mangrove yang sebanyak 28 jenis dari 13 famili yang terdiri dari 26 jenis mangrove sejati dan 2 jenis mangrove ikutan. Zonasi mangrove di Pulau Sembilan yaitu, Avicennia/Sonneratia pada bagian depan dan paku-pakuan (A. Aureum dan A. speciosum) pada bagian yang dekat daratan. Ketebalan mangrove mencapai 134 - 1683 m. Kerapatan mangrove yang ditemukan mencapai 333 - 4601 ind/ha. Penutupan mangrove mencapai 2522 - 5810 cm2/ha. Hasil analisis nilai penting jenis mangrove di Pulau Sembilan menunjukkan bahwa A. marina memiliki pengaruh dan peran yang besar dalam komunitas vegetasi mangrove, terutama pada bagian timur.
