Pemanfaatan tandan kosong kelapa sawit (TKKS) sebagai limbah perkebunan kelapa sawit memiliki kandungan α-selulosa yang berpotensi tinggi untuk pembuatan nanoselulosa sebagai bahan pengisi kertas tisu. Tujuan dari penelitian ini adalah mengetahui karakteristik pembuatan nanoselulosa sebagai bahan pengisi kertas tisu dengan proses ultrasonikasi dan pengaruh penambahan PVA. Nanoselulosa dibuat dengan proses hidrolisis asam, isolasi α-selulosa, ultrasonikasi, dan penambahan PVA. Proses isolasi α-selulosa memiliki nilai kadar α-selulosa sebesar 94,794 %, kadar lignin sebesar 5,029%, dan rendemen sebesar 36,5%. Hasil penelitian ini memiliki nilai rentang diameter terkecil pada amplitudo 50% dengan konsentasi PVA 5% sebesar 11,409 nm-91,837 nm berdasarkan pengukuran SEM. Selain itu, penambahan PVA mampu menahan ukuran nanoselulosa agar tidak bertumbukkan kembali. Nanoselulosa yang didapat ditambahkan bubur kertas, Virgin Coconut Oil (VCO), kitosan, dan tepung tapioka pada pembuatan kertas tisu. Menurut hasil pengujian kertas tisu berdasarkan SNI 14-0103-2008 dengan penambahan nanoselulosa memiliki kualitas yang lebih baik dibandingkan tanpa penambahan nanoselulosa dan penambahan Virgin Coconut Oil (VCO).

Usage of palm oil empty fruit bunch (EFB) as palm oil plantation waste has a α-cellulose content which has a high potential for nanocellulose production as filler tissue paper. The purpose of this research is to determine the characteristics of nanocellulose production as filler tissue paper by ultrasonication process and influence of PVA addition. Nanocellulose was made by acid hydrolysis, α-cellulose isolation, ultrasonication, and PVA addition. Isolation process of α-cellulose produced 94.79% α-cellulose, 5,03% lignin content, and 36.5% yield. The result of research has diameter of nanocellulose as described below an amplitude of 50% with concentration 5% PVA formed of nanocellulose smallest of 11,409 nm-91,837 nm analyzed by SEM.. Addition, the addition of PVA is able to withstand the form of nanocellulose thus it does not collide against. The nanocellulose obtained was added with paper pulp, Virgin Coconut Oil (VCO), chitosan, and tapioca flour on tissue paper production. Based on the tissue test results on SNI 14-0103-2008, tissue paper with the addition of nanocellulose has a better quality than without the addition of nanocellulose and addition of Virgin Coconut Oil (VCO).
