Abstract
Titanium dioksida (TiO2) yang digunakan untuk mendegradasi larutan metilen biru perlu dbuat dalam bentuk lapisan agar dapat digunakan secara berulang. Penelitian ini bertujuan untuk merancang reaktor fotokatalisis tipe plug flow dengan instalasi O2 catcher sebagai media fotodegradasi metilen biru secara realtime, mengukur tingkat degradasi limbah industri metilen biru dengan sensor fotodioda dalam reaktor fotokatalis, serta menghitung perbandingan metilen biru sebelum dan sesudah diproses oleh reaktor fotokatalisis. Pembuatan sampel fotokatalis menggunakan komposisi campuran TiO2: PEG 4000: resin: hardener adalah 2:1:4:1,3 yang dilapiskan dengan kuas pada media kain kasa nilon. Sampel fotokatalis tersebut digunakan dalam reaktor fotokatalisis tipe plug flow, yaitu reaktor degradasi limbah cair secara sirkulasi menggunakan fotokatalis. Proses fotokatalisis memerlukan oksigen sebagai media pembawa elektron sehingga dengan instalasi O2 catcher sebagai pengikat oksigen bebas dari udara. Larutan yang digunakan adalah 5 liter metilen biru 5 ppm dengan lampu TL-UV sebagai sumber cahaya. Degradasi zat warna diukur menggunakan spektrofotometer UV-Vis dan sensor fotodioda. Proses fotokatalisis dilakukan pada variasi debit fluida yaitu 7,2 mL/s, 5,9 mL/s, dan 4,4 mL/s. Proses fotokatalisis secara efektif terjadi pada rentang waktu 0-5 jam dan degradasi signifikan terjadi pada 1 jam pertama penyinaran yaitu untuk debit 7,2 mL/s sebesar 24%, 5,9 mL/s sebesar 29%, dan 4,4 mL/s sebesar 18%. Sedangkan selama 20 jam proses, degradasi untuk debit 7,2 mL/s sebesar 44%, 5,9 mL/s sebesar 50%, dan 4,4 mL/s sebesar 45%.

Titanium dioxide (TiO2) which is used to degrade methylene blue solution needs to be fabricated in the form of a photocatalys sample to be used repeatedly. This research aims to design a plug flow type photocatalysis reactor with o2 catcher installation as a methylene blue photodegradation media's in realtime, measure degradation level of methylene blue with a photodiode sensor in a photocatalyst reactor, and calculate the ratio of methylene blue before and after proses in a photocatalyst reactor. Fabrication of the photocatalys sample using a mixture of TiO2: PEG 4000: resin: hardener is 2: 1: 4: 1.3 which is coated with a brush on the nylon gauze media. The photocatalys sample is used in a plug flow type photocatalysis reactor, which is a circulating liquid waste degradation reactor using photocatalysts. The process of photocatalysis requires oxygen as an electron-carrying medium so that the installation of O2 catcher is added as an oxygen-binding agent from the air. The solution used is 5liter methylene blue 5 ppm with TL-UV lamps as a light source. Dyestuff degradation was measured using UV-Vis spectrophotometer and fotodioda sensor in realtime. The process of photocatalysis is done on fluid discharge variations, namely 7.2 mL / s, 5.9 mL / s, and 4.4 mL / s. In process, effective performance occurs in the range of 0-5 hours and significant degradation occurs in the first 1hour irradiation, namely for discharge of 7.2 mL / s at 24%, 5.9 mL / s at 29%, and 4.4 mL / s at 18%. And within 20 hours of proses, degradation to discharge was 7.2 mL / s by 44%, 5.9 mL / s by 50%, and 4.4 mL / s by 45%.
