Abstract : Hydrogen gas can be produced through the electrolysis process using Hoffman Voltameter method which breaks the water compound into its constituent elements of hydrogen (H2) and oxygen (O2) using DC electric current source. DC electrical current source which is used, it can be derived from the photovoltaic modules (PV) by reason of its use without emitting carbon dioxide or require fossil fuels. This research will be observed the production of hydrogen (H2) with a direct connect system design of the photovoltaic modules (PV) to the electrolysis reactor and converter system designs that use Direct Current to Direct Current (DC-DC). DC-DC converters are designed in this study is used to change the voltage and current of photovoltaic modules (PV) and batteries to increase the production of hydrogen (H2). The research result shows that the direct testing of a hydrogen production of 41,3 ml/h with a light intensity of 30 140 lux, a temperature of 33,8 ° C, the voltage of 19,22 V and a current of 86,8 mA. The amount of light intensity and temperature of the surface of the photovoltaic modules (PV) measured in this study is directly proportional to the power output of photovoltaic modules (PV) and the production of hydrogen gas. DC-DC converters are designed to increase the production of hydrogen gas for the fourth time on testing using the battery as a storage medium. The most optimal production of hydrogen gas occurs in testing using the system design of the photovoltaic modules (PV) using a DC-DC converter 53,1 ml.
