Abstract
Karbondioksida memiliki presentase terbesar di antara pengotor-pengotor lain di dalam biogas. Karbondioksida dalam kandungan biogas merupakan penghambat atau menurunkan kadar CH4 sehingga nilai kalor dari biometana juga menurun. Hal ini menyebabkan daya yang dihasilkan dari biometana juga rendah. Di sisi lain, karbondioksida ini dapat dimanfaatkan untuk pembuatan PCC (Precipitated Calcium Carbonate). Serbuk PCC dapat dimanfaatkan dalam berbagai bidang, seperti: kesehatan, makanan, dan industri. Pada bidang industri, serbuk CaCO3 dimanfaatkan dalam pembuatan kertas, plastik, mantel, tinta, cat, dan pipa polimer. Serbuk CaCO3 dengan kualitas khusus dikembangkan sebagai bahan campuran kosmetik, bahan bioaktif, hingga suplemen nutrisi. PCC dapat dibuat dengan berbagai macam metode, salah satunya metode karbonasi. Metode karbonasi yaitu kalsium oksida yang telah dikalsinasi dilarutkan dalam air (slaking process) membentuk Ca(OH)2, selanjutnya dialiri gas CO2 sampai pH mendekati netral membentuk endapan yaitu PCC. Pabrik Biomethane dan PCC dari POME yang didirikan di Desa Sungai Bahar Tengah Kabupaten Muara Jambi, Sumatera Utara, dengan kapasitas 285.120 ton POME/tahun menghasilkan 73.720.498 m3 Biogas/tahun dan 183.589 ton PCC/tahun.

Carbon dioxide has the largest percentage of other impurities in biogas. Carbon dioxide in biogas content is an inhibitor or reduces CH4 levels so that the heating value of biomethane also decreases. This causes the power generated from biomethane is also low. On the other hand, this carbon dioxide can be used to make PCC (Precipitated Calcium Carbonate). PCC powder can be utilized in various fields, such as: health, food, and industry. In the industrial field, CaCO3 powder is used in making paper, plastic, coat, ink, paint and polymer pipes. CaCO3 powder with special quality was developed as a mixture of cosmetics, bioactive ingredients, to nutritional supplements. PCC can be made with a variety of methods, one of which is the carbonation method. The carbonation method is calcined calcium oxide which is dissolved in water (slaking process) to form Ca(OH)2, then the CO2 gas is drained until the pH approaches neutral to form a precipitate, PCC. The POME Biomethane and PCC plant, which was established in Desa Sungai Bahar Tengah, Kabupaten Muara Jambi, North Sumatra, with a capacity of 285,120 tons of POME/year produces 73,720,498 m3 of Biogas/year and 183,589 tons of PCC/year.
