Abstract

Pertumbuhan penuduk di indonesia yang semakin meningkat setiap tahunnya mengakibatkan kebutuhan energi juga meningkat. Demi membantu kebutuhan energi di indonesia dapat menggunakan teknologi gasifikasi. Gasifikasi merupakan proses termokimia untuk mengubah biomassa padat atau padatan berkarbon menjadi gas sintetik “seperti gas alam” yang mudah terbakar. Proses gasifikasi memiliki 4 tahapan penting yaitu pengeringan, pirolisis, pembakaran dan reduksi. Produk akhir dari gasifikasi adalah gas sintetik atau yang sering disebut syngas (CO, CH4 dan H2). Gas yang dihasilkan dari proses gasifikasi dapat digunakan dapat digunakan sebagai bahan bakar pembangkit (PLTBm) atau juga dapat dibakar langsung. Penelitian ini menggunakan reaktor gasifikasi tipe downdraft dengan bahan bakar biomassa tongkol jagung dan diberikan variasi ukuran tongkol jagung (2 cm, 4 cm, 6 cm dan 8 cm) dan kecepatan masukan udara (3,5 m/s, 7,5 m/s, 11 m/s dan 14,5 m/s). Nilai heat rate tertinggi diperoleh pada variasi ukuran biomassa tongkol jagung 2 cm dengan kecepatan udara masukan sebesar 7,5 m/s yaitu 7,33 kWh dengan efisiensi termal sebenar 44,35%.

The growth of the population in Indonesia which is increasing every year has resulted in increasing of energy needs. In order to help energy needs in Indonesia, gasification technology can be used. Gasification is a thermochemical process for converting solid biomass or carbonaceous solids into flammable synthetic gases "natural gas-like". The gasification process has 4 important stages, namely drying, pyrolysis, combustion and reduction. The final product of gasification is synthetic gas or often called syngas (CO, CH4 and H2). Gas produced from the gasification process can be used as fuel for generation (PLTBm) or can also be burned directly. This research uses a downdraft type gasification reactor with corn cob biomass fuel and given variations in corn cob size (2 cm, 4 cm, 6 cm and 8 cm) and air input speed (3,5 m/s, 7,5 m/s, 11 m/s and 14,5 m/s). The highest heat rate value was obtained at a variation in the size of corn cob biomass of 2 cm with an input air speed of 7.5 m/s, which is 7.33 kWh with an actual thermal efficiency of 44.35%.
