Abstract
Elektrolisis adalah suatu proses penguraian molekul air (H 2 O) menjadi hidrogen (H 2 ) dan oksigen (O 2 ) dengan energi pemicu reaksi berupa energi listrik. Proses ini dapat berlangsung ketika dua buah elektroda ditempatkan dalam air dan arus searah dilewatkan diantara dua elektroda tersebut. Hidrogen terbentuk pada katoda, sementara oksigen pada anoda. Dan untuk meningkatkan konduktifitas listrik dan produksi gas HHO (Brown`s Gas) yang dihasilkan dari proses elektrolisis, diperlukan penambahan katalis, pada penelitian ini katalis yang digunakan adalah NaHCO 3 (Natrium Bikarbonat) dengan variasi prosentase 2,5; 5; 7,5; 10; 12,5 dan 15% yang dilarutkan dalam air aquadest. Metode penelitian yang digunakan adalah metode eksperimental nyata (true experimental method), dengan cara ini akan di uji pengaruh prosentase katalis NaHCO 3 (natrium bikarbonat) terhadap produksi gas HHO (Brown`s gas). Sebagai variabel bebas dalam penelitian ini adalah prosentase katalis NaHCO 3 (natrium bikarbonat) dengan prosentase 2,5; 5; 7.5: 10; 12.5 dan 15%, dengan variabel terkontrolnya adalah tegangan listrik searah 12 V, jenis dan model elektroda stainless steel tipe 316 L berbentuk pipa, volume air elektrolisis 500 ml. Penelitian ini akan menghitung daya listrik yang digunakan untuk menghasilkan gas HHO (Brown`s gas), laju produksi/flowrate gas HHO dan energi yang dihasilkan dari proses elektrolisis gas HHO (Brown`s gas). Hasil penelitian ini menunjukkan bahwa semakin banyak NaHCO 3 (natrium bikarbonat) yang terlarut dalam air akan meningkatkan konsumsi daya listrik, laju produksi gas HHO dan efisiensi generator HHO. Pada prosentase NaHCO 3 12,5 % komsumsi daya menunjukkan daya terbesar sebesar 288 watt, laju produksi terbesar pada 8,083 ml/s dan efisiensi generator terbesar yaitu 21,21%. Setelah prosentase NaHCO 3 mencapai 15% maka, konsumsi daya listrik, laju produksi gas HHO dan efisiensi akan turun.
English Abstract
Electrolysis is a process of water molecule (H 2 O) decomposition to hydrogen (H 2 ) and oxygen (O 2 ) through reaction-triggering energy, which is electric current. process occurred when two electrodes were placed in water and n electric current was passed between two electrodes. Hydrogen was formed at cathode, while oxygen was formed at anode. And to improve conductivity and production of HHO gas (Brown`s gas) that was produced in process, additional catalyst was needed. refore, catalyst used in this research was NaHCO 3 (natrium bicarbonate) in various percentages which are 2.5, 5, 7.5, 10, 12.5, and 15%, that were dissolved in aquadest water. Research method was true experimental method. effect of percentage of NaHCO 3 catalyst (natrium bicarbonate) on production of HHO gas (Brown`s Gas) was investigated. independent variables of this research included various percentages of NaHCO 3 catalyst (natrium bicarbonate) which 2.5, 5, 7.5, 10 and 15 %. Voltage different between two electrodes was kept at 12 V. Type or model of electrode was pipe-shaped stainless steel Type 316 L. volume of electrolyzed water counted to 500 ml. This research was intended to calculate electric power which were used to produce HHO gas (Brown`s gas), flow rate of HHO gas and energy produced in HHO gas (Brown`s gas) from electrolysis process. Result of this research shows that increasing of NaHCO 3 concentration in water, will increase electric current for water electrolysis. largest electric power required is 288 watts at 12.5% of NaHCO 3 . Production rate of HHO and efficiency of HHO generator also increase with increasing of NaHCO 3 percentage in water. highest production rate and HHO generator efficiency were 8,083 ml/s and 21,21% respectively, achived for solution with NaHCO 3 percentage at 12,5%. However, required electric current for electrolysis, production rate of HHO and efficiency of HHO were decreased while percentage of NaHCO 3 was increased to 15%.
