Abstract

Carbon dioxide (CO2) is one of the air polluting gases that can cause various health problems if accumulated indoors. Therefore, finding solutions to capture CO2 indoors is important. One of the efforts to reduce CO2 is by placing microalgae as CO2 capture agents in photobioreactors. This study aims to produce a photobioreactor based on microalgae Chlorella vulgaris, analyse cell density, and measure CO2 absorption by microalgae in the photobioreactor. In this study, cultivation was carried out with continuous lighting, microalgae cell density was calculated using a haemocytometer observed under a microscope, and determination of dissolved CO2 levels using the acid-base titration method in Walne medium. The results showed that a block-shaped photobioreactor with a size of 10×10×27.5 cm and a thickness of 2 mm can be a solution to capture indoor CO2 gas. The density of microalgae cells in the photobioreactor was the highest at 4.9 107 (cells/mL), indicating active photosynthesis. The results also show that the photobioreactor has the ability to capture CO2 gas in the room which is characterised by an increase in dissolved ΔCO2 levels reaching 139.39 mg/L.

Abstract

Industri pelapisan logam atau electroplating merupakan sektor penting dalam dunia manufaktur yang banyak digunakan untuk memberikan lapisan pelindung dan estetika pada berbagai produk logam, seperti bahan bangunan, konstruksi, dan suku cadang kendaraan. Namun, industri ini juga menghasilkan limbah cair yang mengandung logam berat, salah satunya tembaga (Cu), yang bersifat beracun sehingga dapat mencemari lingkungan perairan jika tidak diolah dengan baik. Penelitian ini bertujuan untuk menganalisis penurunan kadar logam Cu dalam limbah cair industri electroplating. Penurunan kadar logam Cu pada limbah electroplating menggunakan metode elektrokoagulasi dengan variasi tegangan, waktu, bentuk elektroda, dan massa elektrolit. Proses dilakukan pada kondisi optimum yaitu tegangan sebesar 12 volt, waktu elektrokoagulasi selama 90 menit, elektroda aluminium berbentuk silinder berlubang, dan penambahan elektrolit NH4Cl sebanyak 1,25 g. Sampel limbah dianalisis menggunakan Spektrofotometer Serapan Atom (SSA). Hasil penelitian menunjukkan efisiensi penurunan kadar logam Cu mencapai 99,79% dengan konsentrasi logam tembaga sebelum dan setelah proses elektrokoagulasi sebesar 1000 ppm menjadi 2,45 ppm. Hasil ini menunjukkan bahwa metode elektrokoagulasi efektif dalam menurunkan kadar logam tembaga pada limbah cair industri electroplating.
