“…Other study indicated that microalgae Tetraselmis sp. had the highest percentage of increasing in population at salinity of 20 ppt with cell density of 677.78 x 10 4 cells/mL [16] . Most of the microalgae tolerated the conditions of environmental changes such as salinity with a very large range and most species of microalgae well performed growth in salinity which was slightly lower than the condition of salinity in its natural habitat [17].…”

“…resistant to high salinity. Study conducted by Ningsih et al [16], indicated that Tetraselmis sp. when given salinity of 30 ppt (normal) lipid level of 1.26% was produced, but when salinity had been reduced to 20 ppt the lipid content was greater than normal salinity reached to 2.64%, and when salinity was increased to 40 ppt the lipid content produced was lower up to 0.19%.…”

Three species of microalgae were used in this study, namely Nitzschia sp., Porphyridium sp., and Tetraselmis sp., which collected from the Lampung Agency of Maricultures -Ministry of Coastal and Marine Affairs. They were cultured in room temperature with 12:12 day light and given different salinities and pH for treatment groups with complete randomized design. Nitzschia sp. and Porphyridium sp. were treated within factorial design 2x2, namely 20 and 40 ppt in salinities and 5 and 10 in pH, while the Tetraselmis sp. was given with factorial 3x3, namely 10, 15, 20 ppt of salinities and 5, 8, 9.5 in pH. All the cultures for 7 days were replicated 3 times. Analysis of variance followed by LSD at 5% level of significant was applied to analyse the data on specific growth rate and total lipid contains. The results indicated that highest growth rate of Nitzschia sp. was in 20 ppt of salinity and at pH of 10, while Porphyridium sp. was in 40 ppt salinity and at pH of 5. But the highest lipid content of Nitzschia sp. was in 40 ppt of salinity with 5 pH, and Porphyridium sp. was in 40 ppt of salinity and 5 in pH. Tetraselmis sp. had the highest growth rate in 20 ppt of salinity and at pH of 9.5, but the highest total lipid of it was in 10 ppt of salinity with 9.5 pH.

“…Naik turunnya salinitas mempengaruhi Thalassiosira sp. yang secara langsung mempengaruhi proses metabolisme, menyebabkan pertumbuhan populasi melambat (Ningsih et al, 2017).…”

“…Salinitas adalah salah satu sifat kimiawi perairan yang secara langsung maupun tidak dapat berpengaruh terhadap pertumbuhan dan aktivitas kehidupan organisme perairan (Ningsih et al, 2017). Kemampuan beradaptasi mikroalga bergantung pada jenis habitat aslinya dan perubahan salinitas.…”

“…Kemampuan beradaptasi mikroalga bergantung pada jenis habitat aslinya dan perubahan salinitas. Hal ini dikarenakan semakin besar perbedaan salinitas dibandingkan dengan habitat aslinya maka, semakin sulit adaptasi yang dilakukan oleh mikroalga, begitu pula sebaliknya (Ningsih et al, 2017). Kisaran nilai salinitas yang optimal untuk pertumbuhan mikroalga bervariasi antara 25-35 ppt (Wahyudi et al, 2022).…”

Thalassiosira sp. adalah salah satu jenis plankton mikroalga yang biasanya digunakan sebagai pakan alami bagi larva udang Salinitas adalah salah satu faktor yang sangat penting dalam budidaya diatom laut, karena dapat berpengaruh terhadap pertumbuhan diatom. Penelitian bertujuan untuk mengetahui pengaruh salinitas yang berbeda terhadap dinamika populasi dan kualitas air Thalassiosira sp. dan menentukan salinitas yang terbaik terhadap dinamika populasi dan kualitas air Thalassiosira sp. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 pengulangan. Adapun perlakuan A yaitu salinitas 20 ppt, perlakuan B yaitu salinitas 25 ppt, perlakuan C yaitu salinitas 30 ppt dan perlakuan D yaitu salinitas 35 ppt. Hasil penelitian menunjukkan bahwa perlakuan dengan menggunakan salinitas yang berbeda memberikan pengaruh nyata terhadap dinamika populasi dan kualitas air Thalassiosira sp. Salinitas terbaik untuk tingkat kepadatan Thalassiosira sp. terdapat pada perlakuan C dengan salinitas 30 ppt yaitu 47.5 x 104 sel/ml yang tertinggi dan perlakuan dengan salinitas terendah berada pada perlakuan D dengan salinitas 35 ppt yaitu 37.4 x 104 sel/ml. Hasil pengukuran kualitas air dengan perlakuan yang menggunakan salinitas yang berbeda (20 ppt, 25 ppt, 30 ppt, dan 35 ppt) menunjukkan nilai kualitas air (suhu, pH, dan intensitas cahaya) masih dalam batas toleransi atau kelanyakan hidup (Baik) Thalassiosira sp.

Introduction: Water territories produce a large number of biota worldwide. The imbalance in conserving aquatic ecosystems, along with the increasing disposal of waste into the environment, has resulted in the risk of contamination of the environment and the resulting biota. The dangers of waste disposal into water can destroy the ecosystem and affect the usability of water for the environment and human beings. Discussion: The PRISMA method was used in this literature review, which examined 35 articles: 23 articles from ScienceDirect, 10 articles from Proquest, and 2 articles from PubMed. Data were analyzed by synthesizing the research variables compared with theory and then presented in the form of tables and figures. The results of this study are presented with a complete narrative description of three sub-discussions, which consisted of the characteristics of microplastics in green mussels (color, shape, size, and abundance). The color was acquired in the dark, with the predominant form of fibers <1 mm in size, which determined the amount of microplastics in green mussels induced by both human and industrial activities, as well as countermeasures through filtration of industrial effluents, the utilization of organic plastics, and policy enforcement. Conclusion: Microplastics found in green mussels in Asian waters vary in their characteristics, with the main determinants of human and industrial activities as well as multi-sectoral countermeasures.
