“…Salinity has a role in the survival of microalgae and can cause inhibition of metabolic activity that correlates to decreased photosynthesis and is related to biomass formation. The findings in this study are also in line with Gu et al (2012) and Aulia et al (2021), who stated that, in general, the formation of microalgae biomass experienced a declination in media with low (<30 ppt) or too high (± 45 ppt) salinity. This condition will relate to decreased photosynthetic efficiency due to stress caused by salinity.…”

“…Therefore, it will not harm nor cause significant fluctuations in microalgae biomass. Aulia et al (2021) stated that salinity is one of the parameters that influences the accumulation of phytoplankton biomass in a culture. Salinity has a role in the survival of microalgae and can cause inhibition of metabolic activity that correlates to decreased photosynthesis and is related to biomass formation.…”

Abstract. Haslianti, Sahidin, Asnani, Fristiohady A. 2023. Growth, biomass, and carotenoids content analysis of Navicula sp. and Chlorella sp. in batch cultures with different salinities. Biodiversitas 24: 4299-4306. The physiological activity of microalgae is strongly influenced by culture conditions. Therefore, the rebound in this microscopic plant blooming phenomenon varies according to the aquatic environmental parameters, especially the salinity of its medium. This study aimed to analyze the cell density, biomass, and carotenoid content of two types of microalgal cultures isolated from the sea of Southeast Sulawesi. This research was conducted from October 2021 to October 2022. The independent variable in this study was salinity (30, 33, and 36‰), and the dependent variables were the parameters of cell density, biomass, and carotenoids content. This study consisted of 135 unit experiments using a completely randomized design (CRD). The same trend in cell density is observed in the two types of microalgae, where exponential growth occurred from day 2 to day 6 and decreased in growth rate on day 7. The biomass content of the two types observed was relatively the same, ranging from 0.0176-0.0181 g, while the carotenoids content ranged from 12.8294-25.5958 g/mL. The highest carotenoids level was found in the type of Chlorella sp. (25.5958 g/mL) while the lowest was in the type of Navicula sp. (12.8294 g/mL). The data indicate that the salinity parameter (>30?36‰) greatly influences and thus spikes growth in cells due to their biomass and high carotenoid content. The environment parameter also contributes significantly to other physiological parameters (one-way ANOVA, p<0.05).

“…Nutrien dan unsur hara merupakan parameter penting yang mendukung pertumbuhan mikroalga (Sigalingging et al, 2019). Aulia et al, (2021), menyatakan bahwa nilai laju pertumbuhan spesifik yang semakin tinggi menunjukkan bahwa daya dukung media terhadap mikroalga semakin baik. Menurut Oktaviani et al, (2017), semakin tinggi kadar nitrat pada media kultur, maka semakin tinggi pula nilai laju pertumbuhan mikroalga.…”

Penelitian ini bertujuan untuk mengetahui pengaruh pemanfaatan kotoran burung puyuh dan pupuk organik guano terhadap populasi serta kepadatan sel Spirulina sp. Penelitian ini dilaksanakan pada bulan 20 Februari sampai 11 Maret 2023 di Laboratorium Fakultas Perikanan Universitas Dharmawangsa. Metode yang digunakan pada penelitian ini adalah metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 pengulangan. Berdasarkan hasil percobaan, perlakuan D menghasilkan rata-rata kepadatan sel Spirulina sp. tertinggi sebanyak 64,33 x 104 sel/ml sedangkan, perlakuan A (Kontrol) menghasilkan rata rata kepadatan terendah sebanyak 23,67 x 104 sel/ml. Hasil laju pertumbuhan harian tertinggi sel Spirulina sp. terdapat pada perlakuan D dengan rata rata 0,372 x 104 sel/ml/hari dan laju pertumbuhan harian terendah terdapat pada perlakuan A (Kontrol) dengan rata-rata 0,172 x 104 sel/ml/hari. Hasil pengukuran parameter kualitas air pada penelitian yaitu suhu berkisar antara 27 - 30 oC, pH berkisar 8,5 - 9,2 dan oksigen terlarut (DO) berkisar antara 6,62 - 7,24 mg/l. Pada penelitian ini dapat disimpulkan bahwa pemanfaatan kotoran burung puyuh serta pupuk organik guano memberikan pengaruh yang sangat nyata terhadap populasi serta kepadatan sel Spirulina sp.

Abstract. Mahmudi M, Arsad S, Fitrianesia F, Ramadhan SF, Arif AR, Savitri FR, Dewinta AA, Ongkosongo AD, Musa M, Lusiana ED. 2023. Microalgae diversity in varying habitat characteristics in Pasuruan and Sidoarjo coastal areas, East Java, Indonesia. Biodiversitas 24: 4418-4426. Microalgae are microscopic eukaryotic organisms which live in various types of habitats. The purpose of this study was to identify the types and the abundance of microalgae in several sub-habitats, namely sediments, mangroves, water columns, and artificial substrates; and to analyze the environmental factors that affect the abundance of microalgae. The research was conducted in several sites in the coastal areas in Pasuruan and Sidoarjo, East Java, Indonesia. A quantitative descriptive method was applied with data collection used a purposive sampling method. Samples were collected using net for planktonic microalgae and using sampling plot for epiphytic and benthic microalgae. The microalgae were grouped using NMDS (non-metric multidimensional scaling) and the relationships between microalgae abundance and water quality parameters were analyzed using CCA (canonical correspondence analysis). The results show that Bacillariophyceae, Cyanophyceae, and Chlorophyceae classes were found in all study sites, but Trebouxiophyceae and Dinophyceae were only found in Pasuruan Beach. The highest abundance of microalgae was found in sediment habitat in Wughoyo Beach, Sidoarjo with 706,605 ind. cm-2. The diversity, the evenness, and the dominance index in both coastal areas ranged from 1.43-2.61; 0.71-0.96; and 0.06-0.27, respectively. Similarity analysis using the NMDS showed that there was no similarity among the three sites, suggesting each site had high microalgal variation. The CCA analysis showed that Bacillariophyceae were found in all sites, indicating its high adaptability. The results of this analysis imply that particular habitat has a unique microalgae diversity, thus preserving diverse habitat types is important.
