Fauziah A, Bengen DG, Kawaroe M, Effendi H, Krisanti M. 2019. Spatio-temporal distribution of microalgae producing chlorophyll and carotenoid pigments in Bali Strait, Indonesia. Biodiversitas 20: 61-67. The Bali Strait waters become a place for various development activities that connect Java Island and Bali Island so that it is thought to have an impact in the life of microalgae that play an important role in the wealth of their water resources. This study aims to explore the spatiotemporal distribution of marine microalgae, which has the potential to produce chlorophyll and carotenoid pigments, as well as their relationship with the environmental characteristics of the Bali Strait waters. The research was conducted at the 5 stations in the morning, midday and afternoon. The data obtained were analyzed using Principal component analysis (PCA) and Correspondence analysis (CA). The results showed that chlorophyll-a, chlorophyll-b and carotenoid were mostly contained by the species Chaetoceros gracilis, Tripos lunula at station 5 (Pang-pang Bay) in the morning, midday and afternoon, and contained by the species Fragilariopsis cylindrus, Thalassiothrix fravenfeldii at station 3 (Ketapang-Gilimanuk ferriage) in the midday and afternoon. Spatially, salinity, ammonia, nitrate, and chlorophyll-a have significantly different values between stations, while temporally the content of chlorophyll-b and carotenoid are influenced by time (in the morning, midday and afternoon).

“…Phosphate, DO, and nitrate parameters had a strong correlation with the phormodium genera with total abundance composition of 8.08%. DO was needed for the oxidation of organic and inorganic materials in the aerobic process [34]. DO concentrations were high which caused a nitrification process that led to produce nitrate compounds [33].…”

Cirata Reservoir is built with water sources originating from the Citarum River. Cirata Reservoir mainly use as a hydroelectric power plant and fish cultivation area with a floating net cage system. The utilization of a reservoir for the cultivation of fish in the Cirata Reservoir had exceeded the specified capacity by the government. That matter had caused the water quality to change in waters of the Cirata Reservoir. Phytoplankton is the first organism that is affected because the degradation of water quality. The purpose of this research is to determine the structure community of phytoplankton in floating net cage areas with different density and water flow at Cirata Reservoir. This research was conducted on November 16 - December 8 of 2019 in the Cirata Reservoir with sampling station located at Jangari, Meleber, and Patokbeusi. The method that was used in this research was purposive sampling method. The result of physic-chemical parameter of this research showed that temperature at all station ranged between 31,9-34,5°C, transparency 53,5-76 cm, pH 6,87-7,67, CO2 8,4-16,8 mg/L, BOD5 1,1-20,5 mg/L, DO 5,83-9,72 mg/L, nitrate 0,169-0,241 mg/L, ammonia 0,001-0,241 mg/L, and phosphate 0,131-0,195 mg/L. The result of phytoplankton community structure indicated that composition of phytoplankton had 30 genera with Chlorophyceae class as the most dominant. The abundance of phytoplankton during research was ranged between 49.570-338.450 ind/L, diversity index 0,78-0,88, domination index 0,12-0,22, and saprobic index 1,04-1,59. Saprobic index indicated that water in each station was included in mild to moderate pollution category or in the β-Meso/ oligosaprobic phased which was showed by the large number of Gloeocystis and Glenodinium genera.

“…Peran sinar matahari untuk membantu proses fotosintesis yang terjadi di dalam tubuh makroalga. Menurut Hamana et al (2018) dengan mengetahui kecerahan suatu perairan kita dapat mengetahui sampai dimana masih ada kemungkinan terjadi proses asimilasi dalam air, lapisanlapisan mana yang tidak keruh dan yang paling keruh. Adapun nilai kedalaman pada setiap stasiun berbeda-beda yaitu berkisar antara 11,7-23,5 cm Stasiun 1 dominan dengan substrat pasir halus dengan persentase 35,69 %.…”

This study aims to determine the distribution patterns, and environmental parameters of macro algae waters in the Intertidal Zone of Malang Rapat waters Gunung Kijang District, Bintan Regency. This research was conducted in October-December 2019. The purposive sampling method was applied to 5 research station based on the different characteristics of each station that found macro algae. Macro algae sampling was carried out at each observation station using line transects. Placing transect lines at every station to collect 3 macro algae along 50 m, the determination of the first plot is based on the first point of finding macro algae that are drawn perpendicular to the coastline with a distance between the lines of 30 m. The results found 8 species of macro algae (seaweed) from 3 divisions namely Caulerpa serrulate, Halimeda opuntia, Chaetomorpha crassa, Sargassum polycystum, Sargassum cristaefolium, Padina australis, Gracilaria salicornia, Galaxaura fastigiate. Distribution patterns of macro algae in the waters of Malang Rapat between -4,212 - 1,708 with the category grouping at station 1 and equivalent at station 2, 3, 4, 5. Each station is dominated by brown algae with the genus Sargassum. Factors affecting the distribution of macro algae in intertidal zone are lights, temperature, pH, current and substrate. All water quality parameters fulfilled the optimum growth requirements of seaweed.
