Abstract

Nutrien nitrat dan fosfat merupakan salah satu faktor pembatas yang berpengaruh terhadap proses pertumbuhan pada ekosistem laut terutama lamun. Penelitian dilaksanakan pada bulan November - Desember 2021 dengan tujuan untuk mengetahui konsentrasi nutrien nitrat dan fosfat pada sedimen serta korelasinya terhadap tutupan lamun di Pulau Harapan dan Pulau Kelapa Dua. Metode yang digunakan dalam penelitian ini adalah metode survei. Pemihan stasiun penelitian menggunakan purposive sampling. Analisis konsentrasi nutrien nitrat dilakukan dengan metode IK-BP2-MU-A-08-2005 dan fosfat dengan SNI 06-6989.31-2005. Analisis korelasi dilakukan dengan metode person-correlation. Hasil menunjukkan bahwa rata – rata tutupan lamun di Pulau Harapan sebesar 43,94% dan Pulau Kelapa Dua 29,42 %. Korelasi nutrien terhadap tutupan lamun di Pulau Harapan menunjukkan nitrat sebesar 0,63 dan fosfat 0,19 sedangkan di Pulau Kelapa Dua nilai korelasi menunjukkan nitrat sebesar 0,43 dan fosfat -0,24. Kesimpulan penelitian menyatakan bahwa konsentrasi nutrien pada Pulau Harapan memiliki hubungan kuat positif untuk nitrat dan sangat rendah untuk fosfat, sedangkan di Pulau Kelapa Dua menunjukkan hasil cukup positif untuk nitrat dan sangat rendah untuk fosfat. Nitrate and phosphate nutrients are one of the limiting factors that affect the growth process in marine ecosystems, especially seagrass. The research was carried out in November - December 2021 with the aim of knowing the concentration of nitrate and phosphate nutrients in sediments and their correlation to seagrass cover on Harapan Island and Kelapa Dua Island. The method used in this research is a survey method. Selection of research stations using purposive sampling. Analysis of the nutrient content of nitrate was carried out with the method of IK-BP2-MU-A-08-2005 and phosphate with SNI 06-6989.31-2005. Correlation analysis was carried out using the person-correlation method. The results showed that the average seagrass cover on Harapan Island was 43.94% and Kelapa Dua Island was 29.42%. Nutrient correlation to seagrass cover in Harapan Island showed nitrate of 0.63 and phosphate of 0.19 while in Kelapa Dua Island the correlation value showed nitrate of 0.43 and phosphate of -0.24. The conclusion of the study was that the nutrient concentration on Harapan Island had a strong positive relationship for nitrate and very low for phosphate, while in Kelapa Dua Island the results were quite positive for nitrate and very low for phosphate.
硝酸盐和磷酸盐营养物质是影响海洋生态系统,特别是海底生态系统生长过程的限制因素之一。这项研究于2021年11月至12月进行,目的是确定沉积物中硝酸盐和磷酸盐营养物质的浓度及其与希望岛和霍克岛二号羔羊覆盖的相关性。本研究采用的方法是调查法。使用有目的的抽样传播研究站。通过IK-BP2-MU-A-08-2005方法进行的硝酸盐营养物浓度分析和通过SNI 06-6989.31-2005进行的磷酸盐分析。使用人员相关性方法进行的相关性分析。结果显示,希望群岛和福克兰群岛的平均覆盖率分别为43.94%和29.42%。岛上营养物质与海洋覆盖的相关性Hope显示硝酸盐为0.63,磷酸盐为0.19,而在Kelapa岛上,两个相关性值显示硝酸盐0.43,磷酸盐-0.24。研究得出的结论是,希望岛的营养物浓度与硝酸盐呈正相关,与磷酸盐的关系非常低,而猎鹰岛二号的营养物含量与硝酸盐的关系非常正,与磷酸盐关系非常低。[NK]硝酸盐和磷酸盐营养素是影响海洋生态系统,特别是海草生长过程的限制因素之一。这项研究于2021年11月至12月进行,目的是了解哈拉潘岛和凯拉帕杜阿岛沉积物中硝酸盐和磷酸盐营养物质的浓度及其与海草覆盖的相关性。本研究采用的方法是调查法。使用目的性抽样选择研究站。硝酸盐的营养成分分析采用IK-BP2-MU-A-08-2005法,磷酸盐的营养成分含量分析采用SNI 06-6989.31-2005法。采用人相关法进行相关分析。结果表明,哈拉潘岛和Kelapa Dua岛的平均海草覆盖率分别为43.94%和29.42%。哈拉潘岛的营养盐与海草覆盖率的相关性为硝酸盐0.63和磷酸盐0.19,而Kelapa Dua岛的相关值为硝酸盐0.43和磷酸盐-0.24。该研究的结论是,Harapan岛的营养物浓度与硝酸盐呈强正相关,与磷酸盐呈极低正相关,而Kelapa Dua岛的结果与硝酸盐呈正相关,与磷呈极低负相关。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
