“…On the other hand, electrolysis of water produces microbubbles (gases O2 and H2). Microbubbles generated from electrocoagulation are highly recommended for further investigation (Das et al, 2022) The combination of O2 and H2 gases is called HHO gas or Brown's gas according to equation (3) (Sudrajat et al, 2020) The results of this study are supported by previous research. The EC system using rectangularshaped Fe anodes has a harvesting efficiency of <85% with an operating time of 3 hours and a precipitation time of 4 hours (Mahmood et al, 2021).…”

Hydrogen gas is considered a pollution-free fuel in the future. However, the EC process using these non-sacrificial electrodes requires further research especially for the production of dissolved hydrogen gas and the efficiency of microalgae harvesting. The purpose of this study was to investigate the concentration of dissolved hydrogen gas produced from the harvesting process of Dunaliella salina microalgae species using EC and ORP concentrations including pH, harvesting efficiency due to voltage variations and harvesting time using EC with non-sacrificial electrodes. D salina harvesting using EC reactor made of cylindrical borosilicate glass. Spiral-shaped type 304 stainless steel (non-sacrificial) serves as the cathode and solid cylindrically-shaped Fe serves as the anode. The voltage set varies between 16, 18, and 20 Volts, while the electrolysis time is varied between 1.3.5 minutes. The results showed that the highest dissolved hydrogen concentration of 820 ppb (0.820 ppm) produced from the EC process used 18 V for 3 minutes. The volume of gas could not be measured because most of the hydrogen gas was dissolved in the D salina culture, so it was not enough to evaporate within 3 minutes. The maximum ORP concentration of -413 mV resulting from the EC process uses 18 V for 3 minutes. When hydrogen gas is present in a solution, it can decrease the ORP value of the solution. At EC time with non-sacrificial electrodes for 5 minutes managed to harvest D salina 50.79%; 61.90%; 74.60% at voltages of 16 V, 18V, and 20 V respectively.

“…The third research objective was to analyze the volume of HHO gas as hydrogen fuel produced during D. salina harvesting using EC with helical electrodes. The combination of O 2 and H 2 through electrolysis is known as HHO gas, hydroxy gas, oxy-hydrogen, or Brown's gas (Sudrajat et al 2020;Subramanian and Ismail 2018). An advantage of EC is that it is more efficient at harvesting microalgae and producing HHO gas, which can be used as fuel gas.…”

<p>Biofuels obtained from renewable sources are the only alternative in the global economy from a sustainable point of view. Microalgae have shown tremendous potential as a major source of biomass production that can be used as biofuels. At the same time, gas hydrogen is a non-polluting energy source because it is produced from renewable sources. This study aims to analyze the harvesting efficiency of Dunaliella salina using electrocoagulation with a helix electrode and having HHO gas as hydrogen fuel. D salina harvesting using an EC reactor made of acrylic is done on a batch scale. Helix-shaped type 304 stainless steel is the cathode, and solid cylindrically-shaped Fe is the anode. The voltage set is 20 Volts, while the electrolysis time is varied between 1. 5. 10. 15. 20. 25 and 30 minutes. The harvesting efficiency of D salina using electrocoagulation with a helix electrode was the highest at 84.74%. The highest concentration of dissolved hydrogen gas was 1.753 ppm. The highest volume of HHO gas was 1978 mL resulting from a 30-minute electrocoagulation with a helix electrode, 20-volt voltage. Nanoscale glovaries are formed on the electrode through heterogeneous nucleation at the solid-liquid interface. After nucleation, the nanobubbles grow, and the buoyancy forces of the growing bubbles cause gas release from the cathode surface. This process continues until it causes many bubbles to produce 1978 mL HHO gas for 30 minutes. During the study, the convex HHO gas formed helped remove coagulated D salina floc through electro-flotation. When the time of D salina harvesting using electrocoagulation with a helix electrode significantly affects D salina harvesting efficiency, gas HHO volume, pH, and temperature, harvesting time has no significant effect on dissolved hydrogen gas concentration and ORP.</p>

Excessive use of electricity produces emissions, as well as carbon will have impact on global warming because electricity mostly still using fossil-based energy. The usage of other alternative energy is beneficial to reduce dependence on the use of fossil fuels. Researchers are currently working to reduce the use of fossil energy by using renewable energy. Among the most common alternative energies found is water, so this research focuses on designing dry cell type HHO (Hydrogen Hydrogen Oxygen) Generator technology with hydrogen gas water electrolysis. The HHO generator functions to break water (H2O) into hydrogen atoms and oxygen atoms, known as HHO. Electrolysis testing using NaCl and a storage tube to see the rise and fall of water from the gas produced. NaCl used weighing 20 grams, 50 grams, 75 grams, and 100 grams dissolved in 500 cc of water. The results of the data obtained, many uses of NaCl produce hydrogen gas faster, the data shows 100 grams of NaCl at 180-210 seconds produces a gas volume of 175 CC compared to 20 grams produces a gas volume of 75 CC, 50 grams produces 125 CC, and 75 grams produces 150 CC
