title: Periodisitas Cahaya dan Asam Amino
Non Esensial pada Nannochloropsis sp.

abstract: Abstrak

Nannochloropsis sp. adalah mikroalga yang biasa digunakan sebagai pakan alami
dalam kegiatan kultur larva ikan dan udang karena memiliki kandungan asam amino
yang tinggi. Ketersediaan asam amino dipengaruhi oleh cahaya dalam proses
fotosintesis. Tingginya asam amino non esensial pada mikroalga akan meningkatkan
nutrisi pakan alami bagi larva ikan dan udang. Tujuan penelitian adalah menganalisis
kandungan asam amino non esensial Nannochloropsis sp. dengan periode penyinaran
berbeda yaitu 18T dan 6T. Penelitian dilaksanakan pada bulan Januari 2012,
bertempat di BBPBL Hanura Lampung. Parameter yang diamati adalah kandungan
asam amino non esensial, laju pertumbuhan, dan kualitas air. Asam amino non
esensial yang terdapat pada Nannochloropsis sp. pada penelitian antara lain asam
aspartat, serin, asam glutamat, glisin, alanin, prolin, dan tirosin. Pengaturan periode
penyinaran Nannochloropsis sp. pada kondisi 18T mempunyai kandungan asam
amino non esensial 134% lebih tinggi dibandingkan 6T. Perubahan kelimpahan sel
Nannochloropsis sp. pada kondisi 18T lebih fluktuatif dibandingkan kondisi 6T.
Kata kunci: Nannochloropsis sp., Fotoperiode, dan Asam amino non esensial





Abstract

Nannochloropsis sp. is marine microalgae commonly used as natural food for fish
larvae and shrimp culture because it has a high composition of amino acids. Amino
acid availability in microalgae affected by light in the photosynthetic processes. The
composition of non-essential amino acids in the microalgae would effect the quality
of natural food for fish and shrimp larvae. The aim of the research was to analyze
composition of the non-essential amino acid on Nannochloropsis sp. under different
photoperiod namely 18T and 6T. The study conducted on January 2012, at BBPBL
Hanura Lampung. The non-essential amino acid composition, growth rate, and water
quality were observed during the research. The non-essential amino acid which are
existed on Nannochloropsis sp. are L-aspartic acid, L-serine, L-glutamic acid,
Glycine, L-alanine, L-proline, L-tyrosine. The composition of non-essential amino
acid on 18T treatment was 134% higher than 6T treatment. Changes in cell
abundance of Nannochloropsis sp. on 18T treatment was more volatile than the 18T
treatment.
