Abstract

HHO (Brwon Gas) adalah hasil dari proses elektrolisis air, pada dasarnya dilakukan dengan mengalirkan arus listrik ke air melalui dua buah elektroda (katoda dan anoda). Agar proses elektrolisa dapat terjadi dengan cepat maka air tersebut dicampur dengan elektrolit sebagai katalis. Katalis dalam peneliatian yang telah dilakukan menggunakan KOH dengan konsentrasi 50mol/L dicampur aquades dengan perbandingan 6 : 4. Untuk mengetahui laju produksi gas hidrogen dibuat sistem monitoring temperatur gas hidrogen menggunakan sensor LM35 dan termokopel tipe K untuk mengetahui temperature gas hidrogen pada storage system. Validasi nilai dari sensor temperatur dilakukan dengan kalibrasi, dari kalibrasi sensor termokopel tipe K menghasilkan sensitivitas sebesar 98,5%, non linierirtas sebesar 11,15%, akurasi sebesar 98,1%, error sebesar 1,9%, dan ketidakpastian berulang sebesar ±1,478. Sedangkan kalibrasi sensor LM35 menghasilkan sensitivitas sebesar 99,97%, non linierirtas sebesar 3,6%, akurasi sebesar 99,67%, error sebesar 0,3 %, dan ketidakpastian berulang sebesar ±1,88. Data kalibrasi sensor menyatakan bahwa sensor masih layak untuk digunakan, sehingga pada penelitian yang sudah dilakukan dengan waktu pengambilan data selama 1 jam 30 menit. Temperatur maksimum pada prodak gas hidrogen yakni 31.79 oC sedangkan pada storage hidrogen temperatur menunjukkan kondisi stabil antara 27.3 oC-28.3 oC ============================================================================================== HHO (Brwon Gas) is the result of a process of electrolysis of water, basically done with an electric current to the water through two electrodes (a cathode and anode). In order for the electrolysis process can happen quickly, the water is mixed with the electrolyte as a catalyst. Catalysts in experiment that have been performed using KOH with a concentration of 50mol / L distilled water mixed with a ratio of 6: 4. To determine the production rate of hydrogen gas made of hydrogen gas temperature monitoring system using LM35 and K type thermocouple to determine the temperature of hydrogen gas in the storage system. Validation of the value of the temperature sensor is done with calibration, calibration type K thermocouple sensor produces a sensitivity of 98.5%, non linierirtas amounted to 11.15%, an accuracy of 98.1%, an error of 1.9%, and recurring uncertainty of ±1.478 , While the LM35 calibration resulted in a sensitivity of 99.97%, non linierirtas by 3.6%, amounting to 99.67% accuracy, error of 0.3%, and recurring uncertainty of ±1.88. Data of sensor calibration stating that the sensor is still feasible to be used, so that the research that has been done by the time of data collection for 1 hour 30 minutes. The maximum temperature at which hydrogen gas prodak 31.79oC while the hydrogen storage temperatures showed a stable condition between 27.3°C-28.3°C
