Waters that are presumably contaminated with heavy metals need to be observed to ensure the level of pollution to perform water restoration. This study was aimed to determine the status of water quality based on heavy metal contents. The survey method was employed in this study, and it was conducted in Pasuruan sea waters in different seasons; September 2019 represented the dry season, and April 2020 represented the rainy season. The water sampling stations were chosen by using purposive sampling in three sampling locations: the sea waters of Kraton, Lekok, and Nguling districts. The heavy metals and water quality parameters were analyzed by using Storet Index. The results indicated that the highest level of heavy metals was found in Lekok waters in September, consisting of Hg (1.22 mg/l), Cd (1.20 mg/l), and Pb (0.55 mg / l). The seawater of Nguling district had the lowest content in April, while Kraton's seawater was moderate. The water quality status based on the Storet Index suggested that the sea waters of Kraton, Lekok, and Nguling districts were classified as moderately polluted with a score of -16 to -24. The highest score was in September in the rainy season with a score of -24 and the score in April in the dry season was -16. It means that the score is increasing but still in the moderately polluted category. The measurement results of temperature, pH, dissolved oxygen, salinity, and current velocity were in optimum results for aquatic organisms in the dry season or the rainy season. Regarding the water quality status in Pasuruan sea waters, it can be concluded that the heavy metal contents exceeded the quality standard set by the government. Therefore, improved management is required to prevent the deterioration of the pollution status in Pasuruan sea waters

The surrounding community activities in the area of milkfish ponds include residential and household waste so that it will affect the water source used for milkfish farms (Chanos chanos Forskal). Due to changes in water quality, it will be known how the condition of pond water quality will affect the abundance of phytoplankton and the growth of milkfish (Chanos chanos Forskal). This study aims to determine the relationship of plankton abundance with the growth of milkfish (Chanos chanos Forskal) in traditional ponds. The method used is the descriptive method. The study was conducted in March - May. The results of the regression analysis for plankton abundance found a relationship that affects a specific growth rate of 83% and 17% influenced by other factors. The correlation coefficient (r) obtained is 0.91 so that it can be said that the abundance of plankton influences the specific growth rate classified as strong. Based on the value of b = 0.0156x (positive relationship) means that if plankton abundance rises the rate of growth also increases by 0.015. If the plankton does not exist or 0 then the rate will decrease by 94.

Seaweeds have an inherent capacity to absorb heavy metals from marine water. This intrinsic ability allows these organisms to accumulate much amount of heavy metals over time. This study conducted at Kupang Village, Jabon Sub-District, Sidoarjo District, where almost 40% of the area consists of Gracilaria sp. ponds cultured. The purpose of this study was to analyze the Pb heavy metals concentration in water culture and its concentration in holdfast and thallus of Gracilaria sp. In this research, determination of samples in each pond was taken on day 0 (before planting), 20 days (Initial Production) and on day 40th (Post/Harvest). The aquatic parameters include salinity, temperature, acidity (pH), and dissolved oxygen (DO). Quantitative determination of heavy metals on sample using Atomic Absorption Spectrophotometry (AAS). Determinations of heavy metal accumulation in organism using Bioconcentratin factor (BCF) and Translocation factor was used to calculate the Pb heavy metal translocation process from the base to the tip of Gracilaria sp. The results of the study showed the highest Pb concentration found in the second sampling age 20 days, in pond 1 with 7.61 ± 0.18 mg.kg-1, and pond 2 was 5.35 ± 0.09 mg.kg-1. This concentration has not exceeded the threshold value that might have an effect if more than 8.6 mg.kg-1. The highest Pb level at the holdfast of Gracilaria sp. found at age 0 days before planting, which is 3.38 ± 0.23 mg.kg-1 and decreases to post-harvest (age of 40 days) which is 0.84 ± 0.00 mg.kg-1. The Transaction Factor (TF) of Pb heavy metal value from holdfast to thallus is 1,015 thus Gracilaria sp. absorbs heavy metals in high concentrations at the beginning of planting and is able to release it again before harvest time. Keywords: Bioaccumulation, Gracillaria sp., Heavy Metal, Histological, Red Algae.
