Pertumbuhan Mikroalga Chaetoceros calcitrans Pada Kultivasi Dengan Intensitas Cahaya Berbeda

Abstract: Chaetoceros calcitrans can be used for natural food in aquaculture. Microalgae growth is influenced by several factors, one of which is light intensity. This study aims to determine the intensity of light that can produce the best growth in C. calcitrans microalgae. The study design used was a completely randomized design (CRD) with two replications. This study uses a treatment (light intensity) with  four levels of treatment, namely 1000 (control), 1500, 2000 and 2500 lux with a duration of lighting 12 hours … Show more

“…The high and low temperatures in the ponds are influenced by the weather, cloud cover and the environmental conditions of the pond itself (Dodd, 2017). High temperatures also accelerate photosynthetic activity (Prasetyo et al, 2022). The optimum temperature for the growth of phytoplankton is around 20-30 o C (Soliha, et al, 2018).…”

“…The media parameters were also measured once every 24 hours during cultivation. In C. vulgaris cultivation, aeration was also given to distribute nutrients well, preventing temperature stratification and fertilizer deposition (Prasetyo et al, 2022). C. vulgaris cell density was calculated every 24 hours for 8 days by taking 1 mL for each C. vulgaris cultivation sample treatment and placing it in a sample bottle.…”

“…Mikroalga ini memiliki kandungan asam lemak jenuh diantaranya asam kaprat 0,30 mg/g, asam palmitate 0,23 mg/g, asam stearate 0,50 mg/g dan asam lemak tak jenuh berupa asam oleat 0,52 mg/g (Dewi, 2017). Keberhasilan pertumbuhan jenis mikroalga ini didukung oleh faktor eksternal seperti suhu dan pH (Endrawati & Riniatsih, 2013), nutrisi dalam media kultur (Hismayasari et al, 2021), cahaya dan lama pencahayaan (Prasetyo et al, 2022). Namun, suhu merupakan salah satu faktor utama yang mempengaruhi pertumbuhan dan metabolisme mikroalga.…”
