“…In addition, it can be assumed that the culture medium becomes more turbid due to the higher dose of coconut water, which causes inhibition of photosynthesis. According to Umainana et al 19 , stated that fertilizer concentrations that are too high or concentrated can cause water in the culture medium to become turbid so that light is difficult to penetrate and phytoplankton growth becomes slow.…”

Spirulina platensis is a microalga that has high economic value. The growth of S.platensis is influenced by environmental conditions and nutrients. The objectives of this study are to determine the best concentration of coconut water for media of S.platensis growth. The study was conducted at the Natural Feed Laboratory of the Brackish Water Aquaculture Center (BPBAP) Ujung Batee Aceh. This research is an experimental study using a completely randomized design (CRD) consisting of 3 levels of treatment and control using coconut water of the media with concentrations of 3%, 5%, and 7% with 3 replications. The highest cell density level of S.platensis reached 83.102 cells/ml in treatment A (3%), in treatment B (5%) 73.975 cells/ml, the density in the control treatment reached 70.850 cells/ml, and in treatment, C (7%) cell density only reached 54.658 cells/ml. The results of the ANOVA test on day 2, day 3, day 5, and day 6 showed that the addition of coconut water with different concentrations had a significant effect (p<0.05) on the growth of S.platensis

“…melakukan penyerapan unsur hara pada media kultur. Konsentrasi nutrien untuk pertumbuhan mikroalga terbagi menjadi 3 yaitu konsentrasi minimum, optimum serta maksimum (Umainana et al, 2012). Hal tersebut diperkuat oleh penelitian lain yang mengatakan bahwa pada mikroalga memiliki batas maksimum dimana kelebihan nutrien yang diberikan kepada mikroalga mengakibatkan proses biosintesis dapat terhambat.…”

Spirulina sp. adalah mikroorganisme autotrof dari kelas Cyanophyta yang berbentuk filamen terpilin menyerupai spiral (helix), dan merupakan salah satu sumber pangan dan pakan yang potensial. Faktor yang mempengaruhi pertumbuhan serta kandungan pigmen salah satunya adalah nutrien. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi urea yang berbeda terhadap laju pertumbuhan dan kandungan pigmen fikosianin pada Spirulina sp. Metode penelitian yang digunakan adalah eksperimental laboratoris dengan menggunakan Rancangan Acak Lengkap. Mikroalga Spirulina sp dikultur dengan 4 taraf perlakuan yang berbeda yaitu pemberian urea 90 mg/L, 105 mg/L, 120 mg/L, 135 mg/L dan 1ml/L pupuk Walne sebagai kontrol dengan tiga kali ulangan. Hasil penelitian menunjukkan laju pertumbuhan tertinggi pada perlakuan kontrol walne sebesar 0,697 dan terendah pada perlakuan 90 mg/L sebesar 0,447. Kandungan pigmen fikosianin tertinggi terdapat pada perlakuan kontrol walne sebesar 0,272 mg/mL disusul dengan perlakuan 120 mg/L, 105 mg/L dan 135 mg/L dengan masing-masing 0,095 mg/mL; 0,068 mg/mL dan 0,046 mg/mL. Berdasarkan hasil penelitian diproleh hasil bahwa perbedaan konsentrasi urea memiliki pengaruh terhadap laju pertumbuhan Spirulina sp. P< 0.05, namun tidak memberikan pengaruh terhadap kandungan pigmen fikosianin mikroalga Spirulina sp. P> 0.05. Spirulina sp. is an autotrophic microorganism from the Cyanophyta class which is in the form of a spiral-like twisted filament (helix), and is a potential source of food and feed. One of the factors that affect growth and pigment content is nutrients. This study aims to determine the effect of different urea concentrations on the growth rate and content of phycocyanin pigments in Spirulina sp. The research method used was experimental laboratory using the Completely Randomized Design. Spirulina sp microalgae were cultured with 4 different levels of treatment, namely urea 90 mg/L, 105 mg/L, 120 mg/L, 135 mg/L, and 1ml/L Walne fertilizer as a control with three replications. The results showed that the highest growth rate was in the Walne control of 0.697 and the lowest was in the 90 mg/L treatment of 0.447. The highest phycocyanin pigment content was found in the Walne control of 0.272 mg/mL, followed by the 120 mg/L, 105 mg/L, and 135 mg/L treatments with 0.095 mg/mL, 0.068 mg/mL and 0.046 mg/mL,respectively. Based on the results of the study, it was found that the difference in urea concentration had effect to the growth rate of Spirulina sp.(P < 0.05), but did not have an effect on the phycocyanin content of microalgae Spirulina sp. P≥ 0.05.

“…(Wibowo, 2014). Sedangkan menurut pendapat Umainana et al, (2012), menyatakan bahwa fase kematian disebabkan oleh beberapa faktor diantaranya adalah temperatur tinggi, kurangnya nutrisi dalam perairan, perubahan pH, kontaminasi, serta berkurangnya proses fotosintesis. Ketersediaan nutrisi yang semakin berkurang setiap hari akan menyebabkan kematian bagi bakteri sehingga dengan adanya toksik yang dihasilkan dari kematian ini juga akan berpengaruh terhadap kehidupan Daphnia sp..…”

Daphnia sp. was natural feed which could adequate the needs of fish fry growth. Fats and fatty acids was main factor which very influenced the success of reproduction and live for hatched larva fish. Fats had important role as the main source. The lack of essencial fatty acid could impact the decrease of fish growth and reproduction. The purpose of this research were to found out the best treatments and the effect of fermented quail feces, bread waste, and tofu waste towards the growth, and increased fats and linoleic fatty acid from Daphnia sp.. The methods of this research was used experimental method and complete randomize design with 4 treatments and 3 repetitions, with density of 100 ind./litre. The treatments which used on this research were treatment A (50% bread waste, 50% tofu waste, and 0% quail feces), treatment B (25% bread waste, 50% tofu waste, and 25% quail feces), treatment C (50% bread waste, 25% tofu waste, and 25% quail feces), and treatment C (25% bread waste, 25% tofu waste, and 50% quail feces) with total combination amount of 200 grams/litre. The data that observed were population of Daphnia sp., fatty acid value, and linoleic fatty acid value.The result of this research showed that Daphnia sp. growth population was valued 502,22 ind/ml – 1949,44 ind/ml, whereas the increasing of fat value from 6,26% became 8,15% and linoleic fatty acid from 0,91% become 6,14%. Acording to the research result could be concluded that the additition of fermented quail feces, and tofu waste gave differences towards the growth, with the fat value increased of Daphnia sp. was 1,89% and linoleic fatty acid was 5,23% and the best treatment for growth and linoleic fatty acid value was the treatment C (50% bread waste, 25% tofu waste, and 25% quail feces) and treatment A (50% bread waste, 50% tofu waste, and 0% quail feces) for the fat value of Daphnia sp.
