ABSTRAK
Larutan KI 2% digunakan sebagai larutan utama yang dioksidasi untukmenghasilkan iodine sebagai indikator terbentuknya agen pengoksidasi. Jumlahiodine yang terbentuk dianalisa melalui metode analisis titrasi iodometri. Kondisioperasi proses yang paling memengaruhi yakni besar lubang diameter dischargeinjektor dan laju alir sirkulasi. Semakin kecil diameter lubang, efektifitaspembentukan agen pengoksidasi semakin meningkat, pada diameter 4 mmmenghasilkan agen pengoksidasi sebesar 7,188 x 10-5 mol/L, diameter 5 mmmenghasilkan 6,563 x 10-5, dan diameter 6 mm menghasilkan 5,000 x 10-5.Semakin besar laju alir maka cavitation number semakin kecil sehingga proseskavitasi semakin efisien dan pembentukan agen pengoksidasi semakin optimum.

ABSTRACT
2% KI solution is used as the main solution is oxidized to produce iodine as anindicator of the establishment of oxidizing agents. Amount of iodine formed wasanalyzed by iodometric titration method. Operating conditions that most affect theprocess is the hole diameter of the discharge injector and the circulation flow rate.The smaller the diameter of the hole more effectiveness on the establishment ofoxidizing agents increases, the diameter of 4 mm produces oxidizing agents of7.188 x 10-5 mol / L, diameter 5 mm yield 6.563 x 10-5, and a diameter of 6 mmproduces 5.000 x 10-5. The greater the flow rate so that the smaller the cavitationnumber the more efficient the process of cavitation and the formation of theoptimum oxidizing agent.
