“…Keberadaan Caulerpa cylindracea berpengaruh terhadap metabolisme mikroba didasar sedimen sehingga mempengaruhi degradasi bahan organik yang berakibat pada komposisi sedimen (Rizzo et al, 2017). Caulerpa racemose dapat digunakan sebagai indikator biologi pencemaran lingkungan karena makroalga ini memiliki kemampuan untuk mengakumulasi logam berat dan mampu menyerap bahan organik seperti nitrat, ammonia dan fosfat (Farizky et al, 2022).…”

The primary sources of organic waste in prawn ponds include feed waste from the farming process as well as ongoing metabolic activity, such as the production of urine and faeces. The increase in organic waste has an impact on reducing the water quality, one of the solutions is by implementing phytoremediation with seaweed. This research aimed to analyzed the growth and ability of seaweed Sargassum sp., Gracillaria sp., and Caulerpa sp. as phytoremediation agents to reduce organic matter in waters. This research was conducted for 68 days and used an experimental method with a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment are A Sargassum sp., B Gracillaria sp., C Caulerpa sp. and D control. The results indicated that treatment C tended to decrease total organic matter (TOM) and sediment organic matter by 123.74 mg/l and 1.37%, respectively. The result also revealed that Caulerpa sp. the most effective seaweed to be used as phytoremediation organic materials in tiger shrimp farms compared to the two other seaweed species (i.e., Gracillaria sp. and Sargassum sp.). The growth of seaweed showed that there was a significant difference in specific growth of seaweed. The best specific growth rate value in treatment C was 1.37 ± 0.1%. The results of this study shown that Caulerpa sp. has more effective remediate organic matter and improve seaweed growth than Gracillaria sp. and Sargassum sp.

Organisms such as Caulerpa racemosa seaweed, which play a pivotal role as primary producers in marine ecosystems, are particularly vulnerable to the deleterious effects of heavy metal exposure. Thus, comprehending the levels of heavy metals, in conjunction with parameters such as the bioconcentration factor (BCF) and geoaccumulation index (Igeo), pertaining to mercury (Hg) and lead (Pb) within the sediment and C. racemosa seaweed in Brondong, Lamongan is imperative for safeguarding the safety of seaweed-derived food products. Sampling of C. racemosa was conducted within traditional seawater ponds utilized for the cultivation of giant groupers, alongside other varieties of seaweed. The concentrations of heavy metals in various anatomical components of the seaweed (ramuli, stolons, rhizoids) and sediment were determined through spectrophotometric analysis utilizing Inductively Coupled Plasma Mass Spectrophotometer (ICP-MS). Laboratory analyses disclosed mercury (Hg) concentrations in C. racemosa ranging from 0.0212 ppm in rhizoids to 0.00437 ppm in ramuli, whereas tin (Sn) concentrations exhibited variability from 0.0392 ppm in rhizoids to 0.0390 ppm in ramuli. While mercury remained undetectable in sediment samples, moderate concentrations of tin were observed at approximately 2.10 ppm. The calculated bioconcentration factors (BCF) for tin in different segments of C. racemosa ranged from 0.0187 ppm to 0.0114 ppm, suggesting a low degree of bioaccumulation. Geoaccumulation index (Igeo) values spanned from -4.1876 to -4.2186 across distinct segments of C. racemosa, indicating marginal accumulation of heavy metals.

Vannamei shrimp (Litopenaeus vannamei) farming in Pinrang Regency faces various challenges, including high mortality rates, slow growth, and attacks by various diseases, which are largely caused by poor water quality. This study aims to assess the potential of using green mussels (Perna viridis) as a biofilter to improve water quality and, in turn, enhance shrimp farming productivity. The research was conducted in Suppa District, using shrimp ponds managed with a traditional system and equipped with water reservoirs. Green mussels were used in the biofiltration system to improve water quality. The results showed that the use of green mussels significantly reduced the concentration of heavy metals such as mercury (Hg), copper (Cu), cadmium (Cd), lead (Pb), and zinc (Zn) in the pond water. This improvement in water quality contributed to an increase in shrimp production to 582 kg/ha, a significant rise compared to the previous production level of 250 kg/ha and the national average of 500 kg/ha. The biofiltration process by green mussels helped reduce pollutants and created a healthier environment for shrimp growth. These findings suggest that using green mussels as a biofilter can effectively improve water quality and Vannamei shrimp farming productivity, while providing an environmentally friendly solution to enhance production yields in the shrimp farming industry in the region.
