Abstract

Abstract: Mouthwash could inhibit the growth of Staphylococcus aureus bacteria in the oral cavity. Albeit, the most widely used today is mouthwash containing clorhexidine that has side effects in prolonged use. Therefore, it is necessary to find new agents as an alternative antibacterial, especially against Staphylococcus aureus. Squid ink is one of the best known seafood used as alternative medicine which has a wide range of therapeutic applications. This study was aimed to evaluate the inhibitory effect of squid ink extract (Loligo sp) on the growth of S. aureus. This was a true experimental study with a post test only control group design. We used modified Kirby-Bauer method using filter papers. Ciprofloxacin antibacterial was used as the positive control and aquadest as the negative control. Extract of squid ink (Loligo sp) and stock of pure bacteria S. aureus bacteria were prepared. The results showed that mean of zone of inhibition of the squid ink extract (Loligo sp) was 11.22 mm which was less than the zone of inhibition of ciprofloxacin. In conclusion, the squid ink extract (Loligo sp) had a moderate inhibitory effect (Himedia category) on the growth of Staphylococcus aureus.
Keywords: extract of squid ink (Loligo sp), Staphylococcus aureus, inhibitory effect

Abstrak: Salah satu cara penanganan bakteri Staphylococcus aureus dalam rongga mulut ialah dengan menggunakan obat kumur. Yang banyak digunaakan saat ini yaitu obat kumur yang mengandung clorhexidine dengan efek samping bila digunakan secara berkepanjangan. Oleh karena itudiperlukan penelitian terhadap agen baru sebagai alternatif antibakteri khususnya terhadap bakteri Staphylococcus aureus. Tinta cumi-cumi merupakan salah satu hasil laut yang dikenal dalam dunia pengobatan alternatif serta memiliki jangkauan yang luas pada aplikasi terapeutik. Penelitian ini bertujuan untuk mengetahui daya hambat ekstrak tinta cumi-cumi (Loligo sp) terhadap pertumuhan bakteri S. aureus. Jenis penelitian ialah eksperimental murni dengan post test only control group design. Metode yang digunakan yaitu metode modifikasi Kirby-Bauer dengan menggunakan kertas saring. Kontrol positif menggunakan antibakteri siprofloksasin dan kontrol negatif menggunakan akuades. Pada penelitian ini digunakan ekstrak tinta cumi-cumi (Loligo sp) dan stok bakteri murni S. aureus. Hasil penelitian mendapatkan bahwa diameter rerata zona hambat dari ekstrak tinta cumi-cumi (Loligo sp) terhadap pertumbuhan bakteri S. aureus sebesar 11,22 mm namun diameter tersebut lebih kecil daripada diameter zona hambat siprofloksasin. Simpulan penelitian ini ialah ekstrak tinta cumi-cumi (Loligo sp) memiliki daya hambat kategori sedang (Himedia) terhadap pertumbuhan bakteri S. aureus.
Kata kunci: tinta cumi-cumi (Loligo sp), bakteri Staphylococcus aureus, daya hambat
