Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pembebanan generator HHO (Hydrogen Hydrogen Oxygen) terhadap kinerja alternator pada sepeda motor matic 125 cc. Generator HHO merupakan teknologi alternatif berbasis elektrolisis air untuk menghasilkan campuran gas hidrogen dan oksigen yang dapat meningkatkan efisiensi pembakaran. Namun, penggunaannya menambah beban listrik pada sistem pengisian kendaraan. Penelitian ini menggunakan metode kuantitatif dengan pendekatan eksperimen, dilakukan pada motor Yamaha Gear 125 cc dalam kondisi stationer, operasional (20 km/jam sejauh ±4 km), serta variasi RPM dan kecepatan. Data diperoleh melalui pengukuran tegangan, arus, dan daya menggunakan multimeter digital, clamp meter, dan tachometer. Hasil pengujian menunjukkan bahwa daya alternator menurun saat generator HHO aktif, dengan rata-rata tegangan turun dari 14,1 V menjadi sekitar 13,8 V, sementara konsumsi daya sistem HHO berkisar antara 47–54 watt. Meski terjadi penurunan daya, sistem pengisian masih berfungsi dalam batas normal dan aman. Dengan demikian, penggunaan HHO dapat diterapkan tanpa modifikasi besar pada sistem kelistrikan, namun tetap perlu evaluasi berkala terhadap kinerja alternator dan baterai. Penelitian ini diharapkan dapat memberikan kontribusi terhadap pengembangan kendaraan hemat energi dan ramah lingkungan. Kata Kunci : Alternator, Sepeda Motor, Generator HHO, Sistem Kelistrikan,, Elektrolisis / This study aims to analyze the effect of HHO (Hydrogen Hydrogen Oxygen) generator load on the performance of the alternator in a 125 cc automatic motorcycle. The HHO generator is an alternative technology that utilizes water electrolysis to produce a mixture of hydrogen and oxygen gases, which can enhance combustion efficiency. However, its use adds electrical load to the vehicle’s charging system. This research employed a quantitative experimental method, conducted on a Yamaha Gear 125 cc motorcycle under stationary conditions, operational use (at 20 km/h for approximately 4 km), and variations in engine speed and RPM. Data were collected by measuring voltage, current, and power using a digital multimeter, clamp meter, and tachometer. The results showed that alternator output power decreased when the HHO system was activated, with average voltage dropping from 14.1 V to around 13.8 V, and HHO power consumption ranging from 47 to 54 watts. Despite this reduction, the charging system remained within safe operational limits. Therefore, HHO integration can be applied without major modifications to the electrical system, though regular evaluation of the alternator and battery performance is still necessary. This research is expected to contribute to the development of more energy-efficient and environmentally friendly vehicles.
