Produktivitas primer sangat mempengaruhi pertumbuhan mangrove. Salah satu indikator pertumbuhan mangrove dipengaruhi oleh sedimen tempat hidupnya yang banyak mengandung makro dan mikronutrien, oksigen, serta air tawar untuk menjaga keseimbangan kadar garam dalam fisiknya. Penelitian ini bertujuan untuk mengetahui kandungan Nitrogen Total dan Fosfat dalam sedimen mangrove dan hubungannya terhadap umur mangrove. Sampel diambil dari tiga stasiun yang memiliki umur mangrove berbeda dengan tujuh titik replikasi. Kedalaman pengambilan sampel adalah 30 cm. Pada masing-masing titik diambil sampel tanah untuk analisa tekstur dan analisa kandungan bahan organik. Pengukuran tinggi pohon dilakukan di setiap titik yang diasumsikan sebagai umur mangrove. Analisa data menggunakan uji regresi linear dan uji korelasi. Hasil penelitian menunjukkan bahwa terdapat hubungan yang nyata antara Nitrogen Total dengan tinggi pohon (regresi linear P = 0,025 < P 0,05). Sebaliknya, tidak terdapat hubungan yang nyata antara Fosfat dengan tinggi pohon (regresi linear P = 0,524 > P 0,05). Hal ini kemungkinan disebabkan oleh faktor-faktor lain seperti iklim, suhu, pH, dan jenis sedimen yang terdapat pada lokasi penelitian. Mangrove was an area with high primary productivity. The primary productivity greatly affects mangrove growth.One of the indicator mangrove growths was sediments by its place that contains macro and micronutrients, oxygen and fresh water to maintain salinity balanced in the physical. The purpose of this study was to determine the content of total nitrogen and phosphate in sediments of mangrove and mangrove relation to age and the results of this study were expected to provide an overview and information about the nutrient content in the form of Total Nitrogen and Phosphate in sediment of Mangunharjo village, Semarang . Samples were taken from three mangrove stations which have a different age with a seven point replication. Samples were collected from three stations of different ages of mangrove with seven replication points. The depth of sampling was 30 cm. At each of these points, soils were sampled for texture analysis and analysis of Total Nitrogen and Phosphate contents. M easurementstree height was applied at each point of different ag e of the mangrove . Analysis of the data used linear regression and correlation tests. The results showed that there was a significant relationship between Total Nitrogen with height of trees (linear regression P = 0,025 < P 0,05). Otherwise, there was no significant relationship between the phosphates with high of trees (linear regression P = 0,524 > P 0,05). It may be caused by other factors such as climate, temperature, pH, and type of sediment found in the study sites. }, issn = {2721-6233}, pages = {65--72} doi = {10.14710/marj.v3i3.5623}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/5623} }
