Abstract
Pembakaran sampah plastik dengan menggunakan insenerator akan menghasilkan gas emisi yang akan merusak lingkungan jika dilepas begitu saja. Emisi ini bisa dikendalikan salah satunya dengan menggunakan teknologi pengendalian pencemaran udara berupa wet scrubber. Salah satu kriteria wet scrubber yang baik adalah efisiensi kontak flue gas dengan air absorber secara optimal. Untuk meningkatkan kontak antara flue gas dengan air absorber digunakan pipa vakum venturi dimana pipa ini akan menarik sebagian emisi gas menuju pipa untuk nantinya tercampur dengan air absorber yang melewati pipa. Selanjutnya, emisi gas dan air akan bersama-sama masuk ke wet scrubber dan melewati media didalamnya. Penelitian ini dlakukan dengan 3 variasi variabel yaitu variabel kecepatan aliran emisi gas sebesar 12 l/min, 14 l/min dan 16 l/min.Variabel debit air sebesar 15 l/min, 20 l/min dan 25 l/min. Serta tebal media dengan tebal 5 cm, 10 cm dan 15 cm. Parameter yang akan diteliti yaitu kandungan NO, CO dan SO₂ pada input dan output wet scrubber, suhu pada inlet wet scrubber serta kandungan air pada bak penampung air limbah yang akan diuji di akhir penelitian. Hasil penelitian ini adalah pada variasi debit air, efisiensi tertinggi pada debit 20 l/min untuk removal gas NO (26.93%), pada debit 25 l/min untuk removal gas CO (32.38%) dan removal gas SO2 (52.78%). Pada variasi aliran emisi gas, efisiensi tertinggi pada aliran 16 l/min untuk removal gas NO (25.82%) dan removal gas SO2 (54.50%) serta aliran gas 14 l/min untuk removal gas CO (32.05%). Sedangkan pada variasi tebal media, efisiensi tertinggi pada tebal 10 cm untuk removal gas NO (30.19%) dan removal gas CO (33.34%) serta tebal 5 cm untuk removal gas SO2 (55.27%).

Burning plastic waste using an incinerator will produce emissions of gas that will damage the environment if released. One of these emissions can be controlled by using air pollution control technology such as wet scrubber. One of the criteria for a good wet scrubber is the optimal efficiency of contact flue gas with water absorber. To increase the contact between the flue gas and the air absorber, a venturi vacuum pipe is used where this pipe will draw some of the gas emission to the pipe to later be mixed with the air absorber that passes through the pipe. Furthermore, gas and water emissions will jointly enter the wet scrubber and pass through the media inside. This research was conducted in 3 variable variations, which are the gas emission flow rate of 12 l/min, 14 l/min and 16 l/min. Water discharge variables are 15 l/min, 20 l/min and 25 l/min. And the thickness of the media with a thickness of 5 cm, 10 cm and 15 cm. The parameters to be investigated are the SO2, NO and CO content in the wet scrubber input and output, the temperature at the wet scrubber inlet and the pH in the waste collection basin. The results for variation of water discharge, the highest efficiency is at discharge 20 l/min for NO gas removal (26.93%), at discharge 25 l/min for CO gas removal (32.38%) and SO2 gas removal (52.78%). In the variation of gas emission flow, the highest efficiency is at 16 l/min for NO gas removal (25.82%) and SO2 gas removal (54.50%) and 14 l/min gas flow for CO gas removal (32.05%). Whereas in the variation of media thickness, the highest efficiency was 10 cm thick for NO gas removal (30.19%) and CO gas removal (33.34%) and 5 cm thick for SO2 gas removal (55.27%).
