Abstract

ABSTRAKDunaliella salina merupakan mikroalga hijau mikroskopis yang dikenal memiliki kemampuan hidup pada kondisi ekstrem dan laju pertumbuhan yang cepat, menjadikannya kandidat potensial dalam pengembangan teknologi budidaya mikroalga yang efisien dan berkelanjutan. Salah satu faktor utama yang memengaruhi pertumbuhan Dunaliella salina adalah ketersediaan nutrien, terutama melalui pemberian pupuk yang sesuai. Penelitian ini bertujuan untuk mengevaluasi efektivitas tiga jenis pupuk, Walne, Guillard, dan Growmore terhadap laju pertumbuhan dan kepadatan sel Dunaliella salina. Penelitian dilakukan melalui kultivasi selama sembilan hari dengan lima perlakuan dan tiga ulangan. Hasil menunjukkan bahwa perlakuan dengan pupuk Growmore 1 ml/L menghasilkan laju pertumbuhan spesifik tertinggi (µ = 0,883 hari⁻¹), diikuti oleh Walne 1,5 ml/L (µ = 0,733 hari⁻¹) dan Guillard 1 ml/L (µ = 0,727 hari⁻¹). Kesimpulan dari hasil penelitian ini bahwa jenis-jenis pupuk dapat memberikan pengaruhi terhadap laju pertumbuhan dan kepadatan sel Dunaliella salina.Kata kunci: Dunaliella salina, kepadatan sel, laju pertumbuhan.ABSTRACTDunaliella salina is a microscopic green microalga that is known to have the ability to live in extreme conditions and a fast growth rate, making it a potential candidate in the development of efficient and sustainable microalgae cultivation technology. One of the main factors influencing the growth of Dunaliella salina is the availability of nutrients, especially through applying appropriate fertilizer. This study aims to evaluate the effectiveness of three types of fertilizer, Walne, Guillard, and Growmore on the growth rate and cell density of Dunaliella salina. The research was carried out through cultivation for nine days with five treatments and three replications. The results showed that treatment with Growmore fertilizer 1 ml/L produced the highest specific growth rate (µ = 0.883 days⁻¹), followed by Walne 1.5 ml/L (µ = 0.733 days⁻¹) and Guillard 1 ml/L (µ = 0.727 days⁻¹). The conclusion from the results of this research is that the types of fertilizer can influence the growth rate and cell density of Dunaliella salina.Key words: Dunaliella salina, cell density, growth rate.
