Abstract

The research entitled "Primary Productivity of Phytoplankton in Mandalika Coastal Area, Central Lombok Regency" was conducted from March to August 2023. This study aims to analyze the primary productivity of phytoplankton and physical and chemical parameters in Mandalika Coastal waters at three different stations (Kuta Beach, Tanjung Aan, and Gerupuk Bay) using dark and light bottles. Based on the results of the study, it is known that Mandalika Coastal waters have phytoplankton primary productivity values ranging from 122.619 - 329.166 mgC/m2/day. The lowest productivity value (122.619 mgC/m2/day) occurs at station III classified as mesotrophic. Station III also has relatively lower physical and chemical parameter values such as an average pH of 7.7 mg/L and an average temperature of 29ºC compared to other stations. The highest productivity value (329.166 mgC/m2/day) occurred at Station II classified as eutrophic and Station I (189.285 mgC/m2/day) also classified as eutrophic. This is supported by pH worth 7.8 mg/L and temperatures ranging from 29.3 - 29.7 ºC, where the value is relatively higher than station III.
龙目岛中部曼达利卡沿海地区浮游植物的初级生产力
题为 "龙目岛中部曼达里卡沿海地区浮游植物初级生产力 "的研究于 2023 年 3 月至 8 月进行。这项研究旨在利用暗瓶和光瓶分析曼达里卡沿海水域三个不同站点(库塔海滩、丹戎安和杰鲁普克湾)的浮游植物初级生产力以及物理和化学参数。根据研究结果可知,曼达里卡沿海水域的浮游植物初级生产力值在 122.619 - 329.166 毫克碳/平方米/天之间。生产率最低值(122.619 毫克碳/平方米/天)出现在属于中营养级的站点 III。与其他站点相比,III 号站点的理化参数值也相对较低,如平均 pH 值为 7.7 毫克/升,平均温度为 29 摄氏度。生产力最高值(329.166 毫克碳/平方米/天)出现在被归类为富营养化的Ⅱ号站,Ⅰ号站(189.285 毫克碳/平方米/天)也被归类为富营养化。其 pH 值为 7.8 毫克/升,温度范围为 29.3 - 29.7 ºC,相对高于 III 站。
