Abstract

Stabilitas dan sifat antarmuka emulsi pickering berperan penting dalam menentukan efektivitas edible coating untuk mengendalikan susut bobot buah pascapanen. Penelitian ini bertujuan mengembangkan emulsi Pickering berbasis kompleks selulosa nanokristalin–kitosan (CNC–kitosan) dan minyak biji kelor, serta mengevaluasi keterkaitan sifat fisikokimia emulsi terhadap penurunan susut bobot tomat selama penyimpanan. Emulsi diformulasikan dengan variasi rasio minyak:air yaitu 1:1 (NCM1), 1:2 (NCM2), dan 1:3 (NCM3) dan dikarakterisasi berdasarkan potensial zeta, sudut kontak, viskositas, indeks emulsifikasi (EI), dan indeks kriming (CI). Struktur antarmuka dianalisis menggunakan SEM. Emulsi diaplikasikan sebagai edible coating pada tomat, dan susut bobot diamati selama 15 hari. Hasil menunjukkan bahwa perbedaan komposisi emulsi secara signifikan memengaruhi stabilitas dan sifat antarmuka. Emulsi NCM2 menunjukkan performa terbaik dengan sudut kontak tertinggi (105,6°), EI stabil, CI terendah, serta lapisan antarmuka yang lebih rigid, sehingga menghasilkan susut bobot tomat terendah, yaitu sekitar 12,6% pada hari ke-15. Emulsi NCM3 juga stabil akibat viskositas dan repulsi elektrostatik yang tinggi, namun efektivitasnya sedikit lebih rendah dibanding NCM2. Temuan ini menegaskan bahwa rigiditas antarmuka lebih menentukan performa edible coating dibandingkan stabilitas koloid semata dan berpotensi memperpanjang umur simpan tomat.

Abstract

Oil palm fronds were one of the plantation wastes that could be utilized as raw material for producing activated carbon. Activated carbon was produced through carbonization and activation processes. This study aimed to obtain the best type of activator in the production of activated carbon from oil palm fronds. The study was conducted experimentally using a Completely Randomized Design (CRD) with five treatments and three replications. The treatments in this study were P1 (NaOH 2.5%), P2 (KOH 15%), P3 (H₃PO₄ 9%), P4 (H₂SO₄ 10%), and P5 (HCl 15%). The observed parameters consisted of moisture content, ash content, volatile matter, fixed carbon, and iodine adsorption. The data were analyzed statistically using the analysis of variance, if Fcount ≥ Ftable then the treatment had a significant effect and the analysis continued with Duncan's Multiple Range Test (DMRT) at the level of 5%. The results showed that the type of activator had a significant effect on all observation parameters. Activated carbon with the best treatment was found on P4 treatment (H₂SO₄ 10%) with a moisture content of 0.49%, ash content of 1.10%, volatile matter content of 2.10%, fixed carbon content of 96.31%, and iodine absorption of 854.46 mg/g.
