Abstract

Penelitian ini bertujuan untuk menganaalisis pengaruh penambahan gas HHO terhadap konsumsi bahan bakar pada sepeda motor matic. Gas HHO dihasilkan melalui proses elektrolisis menggunakan larutan KOH dan H₂SO₄, kemudian dialirkan ke ruang bakar untuk membantu proses pembakaran agar lebih efisien. Pengujian dilakukan dalam dua kondisi, yaitu saat kendaraan dalam keadaan stasioner dan saat operasional. Hasil menunjukkan bahwa penambahan gas HHO mampu menurunkan konsumsi bahan bakar secara signifikan, dengan rata-rata penghematan sebesar 67,99% pada kondisi operasional dan 66,22% pada kondisi stasioner. Proses elektrolisis yang digunakan terbukti efektif dalam menghasilkan gas HHO, yang berperan meningkatkan kualitas pembakaran. Konsumsi daya oleh generator HHO tercatat rata-rata sebesar 8,41 Watt saat operasional dan 8,95 Watt saat stasioner. Sedangkan daya yang disuplai dari baterai ke sistem HHO sebesar 54,06 Watt saat operasional dan 50 Watt saat stasioner. Konsumsi daya generator hanya sekitar 15% dari kapasitas daya baterai pada kondisi operasional dan 17% pada kondisi stasioner, Hal ini menunjukkan bahwa sistem HHO dapat berfungsi secara efisien tanpa memberikan beban berlebih pada sistem kelistrikan kendaraan, serta berpotensi sebagai solusi hemat energi untuk kendaraan berbahan bakar bensin..

HHO gas is produced through an electrolysis process using KOH and H₂SO₄ solutions, then delivered into the combustion chamber to support a more efficient combustion process. The testing was carried out under two conditions: stationary and operational. The results showed that the addition of HHO gas significantly reduced fuel consumption, with an average saving of 67.99% under operational conditions and 66.22% under stationary conditions. The electrolysis process used in this study was proven effective in generating HHO gas, which contributes to improving combustion quality. The average power consumption of the HHO generator was recorded at 8.41 Watts during operation and 8.95 Watts during stationary conditions. Meanwhile, the power supplied from the battery to the HHO system was 54.06 Watts during operational mode and 50 Watts during stationary mode. The generator only consumed approximately 15% of the battery capacity in operational conditions and 17% in stationary conditions. These results indicate that the HHO system can operate efficiently without placing an excessive load on the vehicle’s electrical system and has potential as an energy-saving solution for gasoline-powered vehicles.
