Abstract

Limbah tumpahan minyak di lingkungan, contohnya di laut, merupakan salah permasalahan serius yang memerlukan solusi yang efektif serta ramah lingkungan. Maka dari itu, penelitian ini dilakukan untuk mengembangkan material adsorben berbasis polimer biodegradable yang lebih ramah lingkungan, yaitu Polyvynil Alcohol (PVA). Material ini kemudian disintesis dengan metode electrospinning serta pelapisan (coating) titanium dioksida (TiO₂) untuk meningkatkan performa pemisahan minyak-air. TiO₂ dipilih karena sifatnya yang hydrophobic dan oleophillic. Metode dari penelitian ini terdiri dari sintesis nanofiber PVA dengan metode electrospinning, coating dengan TiO₂, serta pengujian produk. Uji yang dilakukan adalah uji FTIR, uji adsorpsi, uji SEM, uji water contact angle, dan uji kapasitas adsorpsi minyak. Hasil dari penelitian ini menunjukkan bahwa nanofiber PVA berhasil disintesis dengan metode electrospinning. Proses coating dengan TiO₂ mampu meningkatkan sifat hidrofobik permukaan, ditunjukkan oleh peningkatan sudut kontak air. Analisis SEM–EDX mengonfirmasi keberhasilan penempelan partikel TiO₂ pada permukaan serat, dengan durasi coating optimal pada 30 detik. Uji adsorpsi menunjukkan bahwa sampel dengan coating 30 detik memiliki kapasitas serap minyak tertinggi. Dengan demikian, nanofiber PVA berlapis TiO₂ berpotensi sebagai adsorben yang efektif dan ramah lingkungan untuk aplikasi adsorpsi minyak-air.

Oil spill waste in the environment, for example in the sea, is a serious problem that requires effective and environmentally friendly solutions. Therefore, this research was conducted to develop a more environmentally friendly biodegradable polymer-based adsorbent material, namely Polyvinyl Alcohol (PVA). This material was then synthesized by electrospinning and titanium dioxide (TiO₂) coating to improve oil-water separation performance. TiO₂ was chosen because of its hydrophobic and oleophilic properties. This research method consists of PVA composite synthesis by electrospinning, coating with TiO₂, and product testing. The tests carried out were FTIR test, adsorption test, SEM test, water contact angle test, and oil adsorption capacity test. The results of this study indicate that PVA nanofibers were successfully synthesized by the electrospinning method. The coating process with TiO₂ was able to improve the surface hydrophobic properties, indicated by an increase in the air contact angle. SEM–EDX analysis confirmed the successful attachment of TiO₂ particles to the fiber surface, with an optimal coating duration of 30 seconds. The adsorption test showed that the 30-second coating had the highest oil absorption capacity. Thus, TiO₂-coated PVA nanofibers have the potential to be effective and environmentally friendly adsorbents for oil-air adsorption applications.
