Abstract

Pencemaran udara yang diakibatkan oleh gas buang kendaraan bermotor berbahan bakar hidrokarbon sudah pada kondisi yang sangat memprihatinkan. Salah satu alternatif bahan bakar pengganti bahan bakar konvensional adalah hidrogen. Metode yang digunakan untuk menghasilkan hidrogen dalam penelitian ini yaitu dengan cara elektrolisis dan reaksi korosi aluminium. Gas hidrogen dipilih sebagai bahan bakar dikarenakan gas hidrogen tidak menghasilkan emisi COx seperti bahan bakar hidrokarbon umumnya. Adapun penyimpanan hidrogen dengan menggunakan metode adsorpsi pada material berpori seperti karbon aktif dan zeolit untuk meningkatkan energi hidrogen yang tersimpan di storage. Energi hidrogen tertinggi dengan adsorben zeolit pada tekanan 1,7 kg/cm2 dan temperatur 35oC sebesar 9,4365 J/L dan paling rendah tanpa adsorben pada tekanan 0,25 kg/cm2 dan temperatur 33,5oC sebesar 0,9761 J/L. Adapun metode pengujian Internal Combustion Engine yang digunakan dalam penelitian ini yaitu dengan cara mengamati kerja yang dihasilkan oleh Internal Combustion Engine serta mengukur jumlah bahan bakar yang digunakan. Efisiensi kerja merupakan salah satu parameter kualitas suatu mesin konversi energi, dalam hal ini efisiensi kerja Internal Combustion Engine. Adapun hasil penelitian menunjukan efisiensi kerja yang dihasilkan oleh Internal Combustion Engine berkisar antara 25,7–28,4%. Semakin besar laju alir hidrogen maka kerja yang dihasilkan juga semakin besar.Untuk konsumsi energi tertinggi terjadi pada proses pemotongan logam baja. Hal ini dikarenakan baja memiliki tingkat kekerasan atau titik leleh yang lebih tinggi yaitu sebesar 1540°C sedangkan titik leleh aluminium 660,3°C dan besi 1538°C, untuk spesific fuel consumption tertinggi terjadi pada proses pemotongan aluminium. Hal ini disebabkan karena aluminium memiliki densitas yang paling kecil yaitu sebesar 2,7 gr/cm3 dibandingkan dengan baja sebesar 7,85 gr/cm3 dan besi sebesar 7,75 gr/cm3.

Abstract

Hydrogen fuel is one of the alternatives. The existence of constraints in hydrogen-boundary feedstocks in nature causes us to think how to create hydrogen gas. The discovery of aluminum cans of waste which can be a source of hydrogen gas when mixed with acid or base is one of the most calculated means for producing sufficient quantities of hydrogen gas. Used aluminum contained in Coca-Cola, Green sands and Sprite cans as materials corrosion process with variation of electrolyte concentration 0,6 M, 0,8 M and 1 M. The result of research and data processing performed show that by comparing the three types of aluminum waste cans with different levels of produced hydrogen gas, it is found that more and more high concentrations of aluminum are used to produce more hydrogen gas. The largest volume of hydrogen gas is obtained from aluminum coca cola waste with a concentration of 1 M KOH of 0.175 liters (175 ml). The resulting hydrogen gas is then utilized as welding fuel with variations of flow rate and metal welding. The highest Specific Fuel Consumption is obtained when the steel welding is 6579.6186 Joule H2 / cm steel with H2 7L / min flow rate and within 100s the highest welding length is 1.6cm in aluminum welding with a 7L / min hydrogen rate

Abstract

Hydrogen is a more friendly alternative fuel because its only produces moisture.The electrolysis method in alkaline solutions is the simplest way to produce hydrogen. In addition, the use of aluminum cans can increase the amount of gas production. This process use photofoltaic as a direct current supply for electrolysis. This study uses concentration of KOH is 1, 1.5 and M with a mass variation of aluminum 10 gr, 30 gr, and 50 gr. In the process, utilization of circulation and electrolyte regeneration is carried out. Based on the results of the study showed that by utilizing the regeneration process can increase the production of hydrogen gas. And it was found that the more mass of aluminum used with the same concentration can produce more hydrogen gas. The largest volume of hydrogen gas is obtained in aluminum waste with a concentration of 1 M KOH and Al 50 gram which is equal to 12.359 ml/ s. Then also obtained research results from the utilization of fotovoltaic obtained hydrogen gas volume 11.7326 ml/ s current of 13.51A with a concentration of 2M
