Abstract
ABSTRAK Seiring dengan kemajuan dan perkembangan peradaban manusia, tingkat kebutuhan energi juga semakin meningkat.Energi berasal dari pembakaran bahan bakar fosil yang berumur jutaan tahun dan tak dapat diperbaharui. Solusi bagi krisis energi dan bahan baku fosil salah satunya dengan adanya sumber energi alternatif, yaitu biogas. Untuk meningkatkan kualitas biogas dapat dilakukan pemurnian biogas sehingga dapat meningkatkan kadar CH4 dan menyisihkan kadar CO2. Pemurnian dapat dilakukan denganmetode adsorpsi dengan menggunakan adsorben (padatan) yaitu zeolit alam. Pada penelitian ini, biogas berasal dari Pabrik Tahu Wismilak Semarang yang memiliki kadar CH4 136.506,67 ppm dan CO2 345.079,60 ppm. Dilakukan Variasi Ukuran Zeolit dan Tabung Biogas 20 mesh, 50 mesh, dan 80 mesh serta tabung yang berukuran diameter 4 inci panjang 40 cm dan berukuran diameter 2 inci panjang 80 cm. Pemurnian biogas optimal menggunakan tabung berukuran diameter 2 inci panjang 80 cm, sedangkan ukuran zeolit optimal berbeda pada tiap kandungan gas. Peningkatan kandungan gas CH4 optimal dengan ukuran zeolit 50 mesh sedangkan penyisihan gas CO2 optimal dengan ukuran zeolit 20 mesh. Kata kunci: Biogas, Zeolit, Pemurnian Biogas, Adsorsi ABSTRACT Following with the advance and development of human existence, the level of energy needs is also increasing. Energy comes from fossil fuels that already millions of years old and cannot be renewed. The solution of energy crisis and fossil fuels one of them is the presence of alternative energy sources, namely biogas. To improve the quality of biogas can be done with biogas purification so as to increase CH4 levels and set aside levels of CO2. Purification can be done using adsorption method and using the adsorbent (solids) namely natural zeolite. In this research, biogas came from Semarang Wismilak Tofu Factory which had CH4 136,506.67 ppm and CO2 345,079.60 ppm. Variations be done with zeolite size of 20 mesh, 50 mesh, and 80 mesh along with reactors measuring 4 inches diameter, 40 cm long and 2 inches,80 cm long. Optimal biogas purification using a reactor 2 inches diameter, 80 cm long, while the level of optimal zeolite is different in each gas content. The increase optimal in CH4 gas content is with the size of zeolite 50 mesh while the CO2 gas removal optimal is with the size of 20 mesh zeolite. Keywords:Biogas, Zeolit, Biogas Purification, Adsorption
