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
