      Abstract
      Emisi karbon dioksida (CO2) dari aktivitas industri menjadi kontributor utama dalam peningkatan gas rumah kaca yang menyebabkan fenomena pemanasan global serta menimbulkan berbagai dampak negatif, salah satunya bencana hidrometeorologi. Penelitian ini bertujuan mengidentifikasi jejak karbon di area AC factory serta menguji efektivitas Spirulina sp. dalam menyerap CO2 menggunakan alat Carcools yang mengadopsi sistem semi close fotobioreaktor. Penelitian dilakukan selama dua periode, masing-masing 3 kali percobaan selama 8 hari, dengan parameter keberhasilan meliputi biomassa (basah dan kering), kadar protein, dan estimasi serapan CO2. Hasil penelitian menunjukkan bahwa rata-rata biomassa yang dihasilkan sebesar 0,00431 kg dengan serapan CO2 mencapai 0,00817 kgCO2. Efektivitas tertinggi alat Carcools mencapai 51,28% dan kadar protein maksimum dalam biomassa sebesar 5,29% w/w. Cuaca dan intensitas cahaya menjadi faktor pembatas dalam efektivitas penyerapan. Meskipun kandungan protein yang dihasilkan belum optimal, biomassa tetap memiliki potensi pemanfaatan sebagai produk turunan ramah lingkungan lainnya.
       
      Carbon dioxide (CO2) emissions from industrial activities are a major contributor to the increase in greenhouse gases that cause global warming and various negative impacts, one of which is hydrometeorological disasters. This study aims to identify the carbon footprint in the AC factory area and test the effectiveness of Spirulina sp. in absorbing CO2 using Carcools equipment that adopts a semi-closed photobioreactor system. The study was conducted over two periods, each consisting of three experiments lasting eight days, with success parameters including biomass mass (wet and dry), protein content, and CO2 absorption estimates. The results showed that the average biomass produced was 0.00431 kg, with CO2 absorption reaching 0.00817 kgCO2. The highest effectiveness of the Carcools device reached 51.28%, and the maximum protein content in the biomass was 5.29% w/w. Weather and light intensity were limiting factors in absorption effectiveness. Although the protein content produced was not yet optimal, the biomass still has potential for utilization as other environmentally friendly derivative products.
