Abstract

Pigments and chlorophyll are essential for the process of photosynthesis and are characteristic of each species of phytoplankton. This study aims to provide an overview of the pigment quantification method and its potential to identify and estimate biomass of phytoplankton. A literature review has been carried out to identify methods for the extraction and quantification of phytoplankton. The results of the study found that there are at least two main methods most commonly used for the extraction and quantification of phytoplankton, namely spectrophotometric analysis and HPLC. Spectrophotometric is considered a good and practical method for estimating chlorophyll. However, the HPLC has also become the main method for investigating the taxonomic composition of phytoplankton populations. The researchers concluded that there was no significant difference in results between two methods. Spectrophotometric analysis is much cheaper and faster than HPLC, make it a good tool for routine evaluation of chlorophyll. However, the use of HPLC has been proven to be the most appropriate for determining concentration of various pigments in the community of phytoplankton. Regardless of the various advantages and disadvantages of both methods, a good understanding of each method should be a concern in terms of selecting the method to be used according to its designation.

Abstract

Mangroves is a ecosystem can absorb carbon more efective than teresterial vegetataion. The goal of this research is to analyze effectively carbon absorption in the mangrove aea in the Karang Anyar Village. The research was conducted in Karang Anyar Village. Survey and tree sampling were carried out from Juni to August 2024.  Biomass measurements provided information on carbon sequestrtaion. Data obtained was analyzed using allometric equation. Results showed that mean carbon sequestration of the mangrove biomass in Karang Anyar Village was 40,45-69,24 kg C/m2. Carbon sink in mangrove sediment was 402,15-907,95 kg C/m2. This research showed that mangrove ecosystem in Karang Anyar Village held sufficiently high carbon stock. Nevertheless, the future study needs to be directed to carbon stock comparison with other locations in Lampung.
