ABSTRAK
Aspirin termasuk dalam golongan Non Steroidal Anti Inflammatory Drugs (NSAIDs) yang banyak digunakan pada pengobatan nyeri ringan sampai sedang, antipiretik, anti inflamasi, serta anti koagulan. Pada penggunaan secara oral dapat menurunkan efektifitas obat akibat metabolisme lintas pertama. Alternatif untuk mengatasi masalah tersebut yaitu membuat sediaan topikal nanoemulsi aspirin. Nanoemulsi yaitu sistem emulsi yang transparan, tembus cahaya dan merupakan d ispersi minyak air yang distabilkan oleh lapisan film dari surfaktan dan ko-surfaktan, yang memiliki ukuran droplet 20 nm-500 nm. Penelitian ini bertujuan untuk membuat nanoemulsi aspirin dengan variasi konsentrasi etanol 96 % sebagai ko-surfaktan. Nanoemulsi aspirin dibuat dengan Virgin Coconut Oil (VCO) sebagai fase minyak, tween 80 sebagai surfaktan,dan etanol 96 % sebagai ko-surfaktan. Hasil penelitian mendapatkan 5 formula nanoemulsi jernih beraroma khas dengan nilai pH berkisar pada range 4,0-4,5 yang telah memenuhi pH normal kulit. dengan konsentrasi etanol 96 % yaitu 10 %, 15 %, 20 %, 25 % dan 30 %, dan dibuat 3 replikasi. Hasil uji stabilitas fisik menunjukkan bahwa kelima formula menghasilkan nanoemulsi yang stabil dan tidak terjadi pemisahan fase sesudah uji sentrifugasi dan cycling test dilakukan.

ABSTRACT
Acetosal known to be a part of the group medications called Non Steroidal Anti Inflammatory Drugs (NSAIDs) that was used for mild to moderate pain therapy, antipyretic, anti inflamation and anti coagulan. Oral administration of acetosal may decrease its effectiveness because of the first past metabolism problem. The purpose of this study was to formulate acetosal into nanoemulsion form for topical preparation as an alternative to avoid those problem with ethanol 96% as co-surfactant. Nanoemulsion was an emultion system which transparent, glasslike, and comes from dispertion of water and oil stabilized by film-coated that made from surfactant and co-surfactant combination, which has droplet size around 20 nm-500 nm. Acetosal nanoemulsions were prepared with Virgin Coconut Oil (VCO) as oil phase, tween 80 as surfactant and ethanol 96 % as co-surfactant. There were 5 formulas of transparent acetosal nanoemultion. Their yield of pH were about 4,0-4,5 were met the normal skin’s pH. They were acetosal nanoemulsions with ethanol 96 % of 10%, 15%, 20%, 25%, and 30%. These five were stable and did not show the separation of phase after both centrifugation and cycling test.
