Carbomer 940

Salah satu bentuk sediaan mukoadhesif adalah edible film. Bentuk ini dapat meningkatkan waktu tinggal pada mukosa dibandingkan dengan gel oral. Pada penghantaran lokal untuk penyakit mulut seperti sariawan, edible film membantu melindungi luka permukaan sehingga rasa sakit dapat berkurang serta pengobatan lebih efektif. Tujuan penelitian ini adalah optimasi formula basis sediaan edible film menggunakan kombinasi Carbomer 940 dan kappa karagenan dengan merancang beberapa formula secara bertahap sampai didapatkan komposisi formula yang baik. Metode pembuatan sediaan edible film  yang digunakan dalam penelitian ini adalah solvent casting yang evaluasinya berupa kemampuan formula membentuk lembaran sediaan edible film yang kering, tidak lengket dan tidak mudah sobek. Hasil optimasi menunjukkan bahwa basis sediaan edible film menggunakan kombinasi Carbomer 940 dan kappa karagenan menghasilkan sediaan edible film yang baik yaitu formula dengan konsentrasi karagenan sebesar 1,5% dan Carbomer 940 antara 0,1-0,5%. Berdasarkan hal tersebut dapat disimpulkan bahwa formula dengan kombinasi Carbomer 940 1,5% dan kappa karagenan 0,1-0,5% dapat digunakan sebagai basis sediaan edible film.Kata kunci: Mukoadhesif, Edible Film, Polimer, Carbomer, Kappa karagenan

Telah disintesis dan dikarakterisasi edible film komposit karagenan-montmorilonit. Penelitian ini bertujuan untuk memperoleh komposisi dari komponen penyusunedible film (karagenan sebagai bahan dasar, gliserol sebagai plasticizer, dan montmorilonit sebagai filler), mengetahui pengaruh penambahan montmorilonit terhadap sifat fisik dan mekanik edible film, serta mengetahui interaksi yang terbentuk pada edible film. Penelitian dilakukan dalam tiga tahapan, yaitu preparasi awal montmorilonit, uji pendahuluan, dan sintesis edible film komposit karagenan-montmorilonit. Pecetakan edible film menggunakan metode solvent casting. Hasil yang diperoleh dari uji pendahuluan menunjukkan bahwa konsentrasi karagenan dengan sifat mekanik terbaik adalah 3,0% (b/v) dan gliserol 1,5% (v/v). Komposisi tersebut digunakan untuk mensintesis edible film komposit dengan variasi konsentrasi montmorilonit, yaitu 1,0% ; 2,0% ; 3,0% ; 4,0% ; dan 5,0%. Penambahan montmorilonit 1,0 – 3,0% dapat meningkatkan sifat mekanik edible film. Sifat mekanik terbaik dicapai pada konsentrasi montmorilonit 3,0% dengan ketebalan 0,107 mm, kuat tarik 4,139 Mpa, persentase pemanjangan 48,178%, modulus elastisitas 8,590 Mpa, dan WVTR 11,980 g/jam m2. Interaksi edible film komposit yang terbentuk adalah eksfoliasi dan interkalasi

White sweet potato starch (Ipomea batatas L.) and avocado seed starch (Parsea americana Mill) derived from local plants have the potential to be developed as agricultural products. Starch is a hydrocolloid compound as a potential local resource to be utilized. Glycerol function as an anti-freezing which is hygroscopic. This study aims to determine the ratio of white sweet potato starch with avocado seed starch and the concentration of glycerol for making edible film. This study was an experiment using a completely randimized factorial design with 2 (two) main factor consisting of a comparison of white sweet potato starch and avocado seed with 3 levels: P1 = 35%:65%., P2=50%:50%., P3=65%:35% and glycerol concentration with 3 levels: G1=1%., G2=2%., G3=3%. The best result reasearch were content of 23.03% (tratment P1G1), solubility of 55.57% (treatment P3G2)., swelling test of 9.83% (treatment P2g3)., elongation of 8.18% (treatment P3G2)

Pre Treatment

Durian (Durio zibethinus) and cempedak (Artocarpus integer) peels waste are not used by the society. The research aim is to extract pectin from durian and cempedak peels and to formulate the pectin into edible films for food packaging. The research stages were first pre-treatment of durian and cempedak peels, pectin extraction, pectin drying, and  pectin application as edible films with concentration of 0%, 5%, and 15%. Based on this research it was concluded that pectin can be extracted from durian and cempedak peels with yield result of 27.97 % and 55.58 %, respectively. Edible film obtained has  similar characteristics between raw materials cempedak and durian peels. The higher concentration of cempedak peel  pectin increased the thickness, but decreased the tensile strength and elongation at a concentration of 15%. While in edible films from durian peel pectin, the higher concentration of pectin decreased the thickness of edible film on pectin concentration of 15%, lowered tensile strength and raised the edible film elongation.Keywords: waste, durian, cempedak, pectin extraction, edible film

Chitosan, a hydrophilic biopolymer industrially obtained by N-deacetylation of chitin, can be applied as an antimicrobial agent. It highlights the applications of chitosan as an antimicrobial agent against fungi, bacteria, and viruses and as an elicitor of plant defense mechanisms. A series of novel chitosan-sulfathiazole nanocomposite (CSFZ) films were prepared by using solvent casting method for wound healing application. Fourier transform infrared spectroscopy (FTIR) was employed to ascertain the interaction between negatively charged sulfathiazole and positively charged chitosan. Moreover, the antibacterial activity of the films was investigated against gram positive and gram negative microorganisms. It was found that all CSFZ films showed good inhibitory activity against all the tested bacteria as compared to control. The above analysis suggested that the CSFZ films could be used as potential candidates for wound healing application.

Mediated Oxidation

Poly (lactic acid) or PLA was reinforced by nanocellulose and polyethylene glycol (PEG), which were introduced into PLA matrix from 0 to 3 wt.% to enhance compatibility and strength of the PLA. The nanocellulose was prepared by TEMPO-mediated oxidation from microcrystalline cellulose (MCC) powder and characterized by TEM, AFM, and XRD to reveal rod-like shaped nanocellulose with nanosized dimensions, high aspect ratio and high crystallinity. Films of nanocellulose/PEG/PLA nanocomposites were prepared by solvent casting method to evaluate the mechanical performance. It was found that the addition of PEG in nanocellulose-containing PLA films resulted in an increase in tensile modulus with only 1 wt% of PEG, where higher PEG concentrations negatively impacted the tensile strength. Furthermore, the tensile strength and modulus of nanocellulose/PEG/PLA nanocomposites were higher than the PLA/PEG composites due to the existence of nanocellulose chains. Visual traces of crazing were detailed to describe the deformation mechanism.
