“…Similarly, the Dalegan beach point stands out due to its lower nitrate levels in comparison to other beaches. Nitrate levels in the water significantly influence the abundance of planktonic microalgae, as they are essential for photosynthesis, metabolism, growth, and protein synthesis in microalgae (Dayana et al, 2022). Furthermore, DO levels are related to salinity, with higher salinity values resulting in lower dissolved oxygen content in the waters (Daroini & Arisandi, 2020).…”

The East Java coast has biodiversity potential, including microalgae. Microalgae are primary producers for the aquatic ecosystem, whose distribution depends on water quality parameters and sub-habitat characteristics. The purpose of this study was to analyse and identify the microalgae, as well as environmental quality parameters based on sub-habitat characteristics in the northern part of the East Java coast, Indonesia. The research was conducted from March to June 2023. Sample sites were determined using purposive sampling techniques at nine sites located in Gresik, Lamongan, and Tuban coasts. Water samples were collected from various sub-habitats, including the water column, sediments, rocks, mangroves, artificial substrates, macroalgae, and water plants consisting of water hyacinth (Eichhornia crassipes) and Coontail (Ceratophyllum demersum). The obtained results depicted microalgae found were from Bacillariophyceae, Chlorophyceae, Chrysophyceae, Coscinodiscophyceae, Cyanophyceae, Dinophyceae, Trebouxiophyceae, and Zygnematophyceae. Bacillariophyceae dominated the community in all sites. The expected outcome of this study is to provide and complete the database of microalgae morphologically based on sub-habitat characteristics, particularly on the north coast of East Java, Indonesia.

“…Mikroalga di Indonesia mempunyai sekitar 200.000-800.000 spesies yang ditemukan, 35.000 spesies sudah diidentifikasi (Hadiyanto & Azim, 2012). Mikroalga termasuk mikroorganisme uniseluler atau multiseluler yang memiliki banyak jenis, ukuran dan bentuk, mempunyai pigmen, dan merupakan fotoautotrof (Dayana et al, 2022). Mikroalga dapat tumbuh dengan cepat dan baik pada lingkungan perairan garam atau air tawar (Yanuhar, 2016).…”

Food is a basic human need with nutritional value for the body's needs. Food in this modern era is growing rapidly, so consumers think of choosing food for their body needs and health effects. There is a world fact that most countries experience a food shortage crisis that causes the emergence of a disease, namely kwashiorkor, which experiences protein deficiency. This crisis can be solved by providing functional foods that contain high protein. One type of food that contains much high protein is Spirulina platensis. This microalga can be cultivated in media containing nutrients from inorganic fertilizers commonly used for plants. The purpose of this study was to analyze the waste of modified Zarrouk media and to analyze the quality of Spirulina platensis biomass as a functional food ingredient grown on the modified media. The stages of this research included collecting data on the production process of Spirulina platensis, sampling Spirulina platensis biomass, and analyzing the quality test of the biomass and Spirulina platensis media waste. Laboratory tests for biomass consist of metal contamination, dyes, bacterial contamination, and proximate (moisture content, ash content, crude fat, crude fiber, crude protein). In contrast, the lab tests for the media consist of media samples before and after being used for cultivation. The results of the Spirulina platensis biomass quality test showed that it met the requirements as a functional food ingredient, and the media waste was not harmful to the environment. ABSTRAK Pangan di era modern ini semakin berkembang dengan cepat, sehingga konsumen memilih makanan tidak hanya untuk kebutuhan tubuh saja tetapi memberikan efek kesehatan. Adanya fakta dunia bahwa sebagian besar negara mengalami krisis kekurangan pangan hingga menyebabkan munculnya penyakit yaitu kwarsiokor, di mana mengalami kekurangan protein. Krisis ini bisa diselesaikan dengan cara memberikan makanan fungsional yang mengandung protein tinggi. Salah satu jenis makanan yang banyak mengandung protein tinggi yaitu mikroalga Spirulina platensis. Mikroalga ini dapat dibudidayakan pada media yang mengandung nutrisi dari pupuk anorganik yang biasa digunakan untuk tanaman. Tujuan penelitian ini untuk menganalisis limbah media Zarrouk modifikasi dan menganalisis kualitas biomasa Spirulina platensis sebagai bahan pangan fungsional yang dibudidaya pada media modifikasi tersebut. Tahapan penelitian ini mencakup pengambilan data proses produksi Spirulina platensis, pengambilan sampel biomassa Spirulina platensis, dan menganalisis uji kualitas biomasa serta limbah media Spirulina platensis. Uji laboratorium untuk biomasa terdiri dari cemaran logam, zat warna, cemaran bakteri, dan proksimat (kadar air, kadar abu, lemak kasar, serat kasar dan protein kasar). Sedangkan uji lab untuk media terdiri dari sampel media sebelum dan setelah digunakan budidaya. Hasil uji kualitas biomassa Spirulina platensis tersebut menunjukkan syarat sebagai bahan pangan fungsional, limbah media yang digunakan untuk produksi biomassa tidak berdampak pada lingkungan.

“…Large currents can cause microalgae to be carried away (Bhushan et al 2020). Slow currents are a suitable habitat for microalgae (Dayana et al 2022). Currents that are too strong above 0.5 m. s -1 can disrupt the ecological balance of the waters that have been formed (Ravindran 2016).…”

“…Dissolved oxygen (DO) is influenced by organic matter. The higher the organic matter, the lower the dissolved oxygen content in the waters (Dayana et al 2022). DO concentration in waters is also affected by the presence of waste such as plastic, leaves, and branches (Paris et al 2022).…”

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.
