Abstract

Konsumsi dan produksi plastik yang tinggi menyebabkan penumpukan sampah plastik yang memiliki dampak negatif bagi lingkungan. Hal tersebut disebabkan plastik sulit terdegradasi. Salah satu alternatif solusi permasalahan ini adalah dengan menciptakan kemasan yang mudah terdegradasi, yaitu bioplastik. Kehilangan makanan telah menjadi permasalahan global, salah satu sebabnya adalah pembusukan akibat mikroba di sepanjang rantai pasok yang menyebabkan umur simpan produk berkurang. Kini tuntutan akan kemasan pangan yang memiliki fungsi aktif dibutuhkan demi menjamin keamanan pangan dan meningkatkan umur simpan produk yang dikemas, salah satunya adalah kemasan aktif antibakteri. Studi ini bertujuan untuk mengidentifikasi potensi bioplastik ramah lingkungan dengan penambahan agen antibakteri untuk menjadi kemasan aktif antibakteri. Metode yang digunakan dalam kajian ini adalah studi literatur. Hasil kajian menunjukkan adanya potensi pengembangan bioplastik antibakteri menggunakan bahan-bahan alami. Pengembangannya diharapkan dapat mengurangi penggunaan plastik konvensional dan mengurangi tingkat kehilangan makanan karena kontaminasi mikroba.

Abstract

Titanium dioxide (TiO2) has been known to have anti-microbial activity against fungi, bacteria, and viruses. The application of TiO2 in the membrane attached to the air conditioner was expected to minimize airborne microorganisms. This study contribution to investigate the efficacy of UV-assisted TiO2 photocatalysis in controlling airborne microorganisms in the seasoning powder industry. TiO2 was coated to the non-woven membrane and attached with a UV lamp inside the air conditioner. When the AC was on, the Ti3+ was released into the air. Enumeration of airborne microorganisms was conducted by opening the agar plates for 15 min at several food processing facilities, followed by incubating agar plates for 72 hours at 30 °C. The result shows dry processing facility had the highest number of initial airborne bacteria while the wet production facility had the highest number of initial airborne fungi. Interestingly, the number of airborne microorganisms fluctuated in the packaging facility related to the number of people going inside and outside. On the contrary, the number of airborne microorganisms was deficient in empty rooms, which indicated that the number of airborne microorganisms might be related to people and products. Overall, airborne microorganisms were reduced after 60 min of irradiation. Therefore, it is recommended to irradiate the facilities for 60 min before production start. SEM images and EDAX analysis results show TiO2 was detected after 160 h. However, it was recommended to change the TiO2 membrane after one month. This research was expected to contribute to controlling airborne microorganisms during food production in food processing facilities.
