Abstract

Konsorsium mikroalga merupakan interaksi antara dua atau lebih spesies mikroalga yang hidup berdampingan dan dapat bersimbiosis untuk tujuan tertentu. Penelitian ini bertujuan untuk menguji kemampuan konsorsium Chlorella vulgaris dan Spirulina platensis dalam penerapan teknologi Carbon Capture and Storage (CCS). dengan mengamati laju fotosintesis, laju pengikatan, dan efisiensi penyerapan CO2. Konsorsium dikultivasi dalam medium Walne yang telah dimodifikasi dengan penambahan NPK sebesar 30 ppm, menggunakan variasi rasio kultur 0:1, 1:0, 1:1, 2:1, dan 1:2, serta dua variasi laju alir CO₂ sebesar 30 ml/s dan 60 mL/s. Hasil uji statistik diketahui perbandingan konsorsium mikroalga berpengaruh (p ≤ 0.05) terhadap efisiensi pengikatan CO₂ dan laju fotosintesis. Sedangkan, laju alir hanya berpengaruh (p ≤ 0.05) pada laju pengikatan CO2. Parameter efisiensi pengikatan CO2 memiliki korelasi kuat (r = 0.8) terhadap laju fotosintesis. Parameter laju pengikatan CO2 memiliki korelasi sangat lemah (r = 0.1) terhadap efisiensi pengikatan. Serta, parameter laju fotosintesis memiliki korelasi negatif yang bersifat lemah (r = -0.4) terhadap laju fotosintesis. Perlakuan P6 (Rasio konsosrsium 1:1 Laju alir 60 ml/s) memperlihatkan hasil pengikatan CO2 tertinggi pada 7976 mg/L/jam. Disamping itu, perlakuan P4 (konsorsium 0:1 60 ml/s) menunjukkan efisinesi pengikatan CO2 tertinggi pada 1023%. Serta, perlakuan P3 (konsorsium 0:1, 30 ml/s) menunjukkan laju fotosintesis tertinggi pada 6.53 gr/L/hari. Pengamatan morfologi menunjukkan C. vulgaris tidak mengalami perubahan bentuk sel sedangkan S. platensis mengalami perubahan morfologi dari spiral menjadi linier.

Microalgal consortium refers to the interaction between two or more microalgae species that coexist and may engage in symbiosis for specific purposes. This study aimed to evaluate the capability of a consortium of Chlorella vulgaris and Spirulina platensis in the application of Carbon Capture and Storage (CCS) technology by observing the photosynthetic rate, carbon fixation rate, and CO₂ absorption efficiency. The consortium was cultivated in Walne medium modified with the addition of 30 ppm NPK fertilizer, using variations in culture ratios (0:1, 1:0, 1:1, 2:1, and 1:2) and two CO₂ flow rates (30 mL/s and 60 mL/s). Statistical analysis revealed that the consortium ratio had a significant effect (p ≤ 0.05) on CO₂ absorption efficiency and photosynthetic rate. Meanwhile, flow rate showed a significant effect (p ≤ 0.05) only on the CO₂ fixation rate. The CO₂ absorption efficiency exhibited a strong positive correlation with the photosynthetic rate (r = 0.8), while the carbon fixation rate showed a very weak correlation with absorption efficiency (r = 0.1). Additionally, the photosynthetic rate had a weak negative correlation (r = –0.4) with the carbon fixation rateTreatment P6 (consortium ratio 1:1 with CO₂ flow rate of 60 mL/s) showed the highest CO₂ fixation rate at 7976 mg/L/hour. Treatment P4 (consortium ratio 0:1, 60 mL/s) exhibited the highest CO₂ absorption efficiency at 1023%, while treatment P3 (consortium ratio 0:1, 30 mL/s) showed the highest photosynthetic rate at 6.53 g/L/day. Morphological observations indicated that C. vulgaris did not undergo any noticeable changes in cell structure, whereas S. platensis experienced a morphological transformation from a spiral to a linear form.
