Abstract
Gas HHO atau brown gas diproduksi dari elektrolisis air oleh
generator gas HHO (GHHO). Unjuk kerja generator gas HHO dipengaruhi oleh
elektroda, elektrolit, dan arus listrik searah. Elektroda titanium memiliki nilai
konduktifitas termal lebih tinggi dan resistivitas listrik lebih rendah dari
stainless steel. Gas HHO ditambahkan pada sepeda motor melalui intake
manifold kedalam mesin. Penelitian ini bertujuan untuk mengetahui pengaruh
elektoda titanium pada unjuk kerja generator gas HHO dan mengetahui
pengaruh penambahan gas HHO terhadap unjuk kerja dan emisi gas buang
sepeda motor.
Unjuk kerja GHHO yang diuji dengan penambahan PWM variasi
duty cycle dari 20%, 40%, 60%, & 80% dan tanpa penambahan PWM.
Parameter yang diukur tegangan listrik, arus listrik, temperatur elektrolit, debit
gas HHO, dan waktu pengujian dan yang dihitung daya listrik, laju produksi
gas HHO, produksi gas HHO spesifik, dan efisiensi GHHO, selanjutnya gas
HHO dari variasi terbaik diaplikasikan pada sepeda motor Honda CB150R.
Unjuk kerja sepeda motor yang diukur torsi, kadar emisi gas buang (CO2, O2,
HC, & CO), data akusisi temperatur (mesin, oli mesin, & gas buang), laju
konsumsi bahan bakar dan dihitung daya, tekanan efektif rerata, efisiensi
termal, dan konsumsi bahan bakar spesifik.
Hasil dari penelitian unjuk kerja generator gas HHO dihasilkan
efisiensi tertinggi variasi duty cycle 40% senilai 42,15%. Waktu pengujian
terlama variasi duty cycle 20% selama 240 menit. Kebutuhan daya tertinggi

buang pada rpm 7000, CO =8,21%vol., CO2 = 8,39%vol., O2 = 2,03%vol., dan
HC = 165.000 ppm vol. Bahan bakar pertamax dengan penambahan gas HHO menghasilkan torsi

The HHO gas or brown gas produced from water electrolysis by a gas
generator (GHHO). The performance of the HHO gas generator influenced by
electrode, electrolyte and direct current. Titanium electrode’s thermal
conductivity is higher, and its electrical resistivity is lower than a stainless steel.
The HHO gas added to the motor cycle through the intake manifold to the
engine. The purpose of this research is to understand the influence of titanium
electrode towards the performance of HHO gas generator and to understand the
affection of the addition of HHO gas against its performance and also the gas
emission of the motorcycle.
The GHHO performance was being tested by the augmentation of
PWM with the variation of duty cycle from 20%, 40%, 60% and 80% and
without PWM addition. The measured parameters are electrical voltage,
electrical current, temperature of the electrolyte, discharge of the HHO gas,
testing time, electrical power, production rate of HHO, specifications of HHO
gas production and its efficiency. After all, the best variation was being
implemented to the motorcycle type HONDA CB150R. The performance
parameters of motorcycle that being measured is torch, emission level CO2, O2,
HC & CO), acquisition temperature (engine, engine oil, emission and radiator),
the rate of fuel gas consumption, average effective pressure, thermal efficiency
and the consumption of specific fuel.
The results of the research performance of the HHO gas generator
produced the highest efficiency of 40% duty cycle variation amounting to
42.15 %. Longest test time variation of 20% duty cycle for 240 minutes. The
highest power requirement amounting to 104.72 watts at direct variation
conncetion. And the results of the research performance motorcycle engine fuel
pertamax produces the hightest torque worth 18.674 N.m, the highest worth
13.255 kW power, thermal efficiency amounting to 36,09%, the highest mean
effective pressure amounting to 1366.404 kPa, and the exhaust gases at 7000
rpm , CO = 8.21% vol. , CO2 = 8.39% vol. , O2 = 2.03% vol. and HC =
165.000 ppm vol. And fuel pertamax with the addition of HHO gas produces the highest torque
worth 19.267 N.m, the highest worth 17.39 kW power, highest thermal
efficiency amounting to 40.27 %, the highest mean effective pressure
amounting to 1463.648 kPa as well as the exhaust gases at 7000 rpm ,
CO=8.17% vol. , CO2 = 8.65 % vol. , O2 = 1.76% vol., and HC = 151.000
