Abstract

Penelitian mengenai penggunaan bio-fuel pada kompor tanpa tekanan (ordinary multi wick stove) sebagai pengganti minyak tanah belum pernah dilakukan secara ilmiah. Hal ini disebabkan bio-fuel mempunyai viskositas tinggi, nilai kalor lebih rendah dibanding kerosin, dan sulit dibakar.

Uji laboratorium dilakukan di Laboratorium Teknik Pembakaran dan Bahan Bakar – Teknik Mesin ITS menggunakan kompor sumbu 18 dengan bahan bakar Kerosene, Direct Jatropha Curcas Oil 100%, dan Methylester Jatropha Curcas 100%. Bahan bakar sekunder yang digunakan adalah spiritus. Penyalaan awal dilakukan dengan menyemprotkan bahan bakar sekunder ke ruang bakar kemudian dinyalakan menggunakan pemantik api otomatis. Jumlah bahan bakar sekunder yang disemprotkan mulai 3 cc hingga 30 cc dengan interval kenaikan 3 cc.

Hasil penelitian menunjukkan bahwa penggunaan mekanisme penyalaan awal membuat waktu yang dibutuhkan untuk menyalakan kompor kerosene semakin cepat sebesar 18,7% pada volume bahan bakar sekunder 18 cc. Pada volume semprotan bahan bakar sekunder 18 cc, untuk menyalakan kompor Direct Jatropha Curcas Oil membutuhkan waktu paling lama daripada Methylester Jatropha Curcas Oil dan Kerosene.
==================================================================================================================================
Research for biofuel as fuel for unpressurized stove has never been done experimentally. This is because biofuel has high viscosity, is difficult to burn, and also has a lower heating value than Kerosene.

Testing of this stove is performed at the Combustion Laboratory – Mechanical Engineering of ITS using the Laboratory Experimental Case Method. By comparing the injection performance among Kerosene, Methylester Jatropha Curcas Oil 100%, and Direct Jatropha Curcas Oil 100%, and also using flammable pre-ignition fuel like spiritus in volumes starting from 3 cc until 30 cc, this experiment was accomplished successfully.

The result shows that using this pre-ignition mechanism will increase the ignition time of the Kerosene stove by 18.7% faster than manually with 18 cc volume of pre-ignition fuel. At 18 cc volume of pre-ignition fuel, the Direct Jatropha Curcas stove has a longer ignition time than other fuels such as Kerosene and Methylester Jatropha Curcas Oil.
