Hosnah, Kamiliyah Wiladatul (2017) Pengaruh Fotoperiode Yang Berbeda Terhadap Pertumbuhan, Produksi Biomassa Dan Klorofil-A Chaetoceros Calcitrans. Sarjana thesis, Universitas Brawijaya.
Abstract
Tujuan penelitian ini yaitu untuk menjelaskan pengaruh fotoperiode yang berbeda terhadap pertumbuhan dan menentukan fotoperiode terbaik untuk pertumbuhan, produksi biomassa dan klorofil-a Chaetoceros calcitrans. Metode yang digunakan adalah metode eksperimen RAL dengan 4 perlakuan dan 3 ulangan. Perlakuan penelitian ini menggunakan perbedaan fotoperiode (terang:gelap) 24:0, 18:6, 12:12, 6:18. Hasil penelitian menunjukkan bahwa fotoperiode yang berbeda berpengaruh terhadap pertumbuhan, produksi biomassa dan klorofil-a Chaetoceros calcitrans. Pada penelitian ini, didapatkan fotoperiode terbaik untuk pertumbuhan pada fotoperiode 18:6 (terang-gelap) sebesar 17,5 x 106 sel/mL, produksi biomassa 0,413 g L-1, dan klorofil-a 4,93 mg L-1. Berdasarkan hasil penelitian dapat disimpulkan bahwa fotoperiode 18 jam dapat menghasilkan pertumbuhan, produksi biomassa dan klorofil-a Chaetoceros calcitrans secara maksimal.
English Abstract
The purpose of this study was to describe the influence of different photoperiods on the growth, biomass production and chlorophyll a and determine the best photoperiods on the growth rate, biomass and chlorophyll a production of Chaetoceros calcitrans. The method used was a completely randomized design with four treatments and three replications. Different photoperiods was used in this study of 24:0, 18:6, 12:12, 6:18 (light:dark) circle were investigated. The results showed that different photoperiods were significantly influence the growth, biomass and chlorophyll-a production of Chaetoceros calcitrans. In this study, the best photoperiod in 18: 6 (light-dark) circle with the maximum cell concentration of 7,5 x 106 cell mL-1, biomass of 0,413 g L-1, chlorophyll-a production of 0,493 mg L-1. In conclusion, 18 hours light period was the best photoperiod for affect the growth, biomass and chlorophyll-a production of Chaetoceros calcitrans
