UJI DAYA HAMBAT EKSTRAK KENTAL DAUN KRATOM (Mitragyna speciosa Korth) TERHADAP BAKTERI Staphylococcus aureus SEBAGAI PENYEBAB JERAWAT
Main Article Content
Abstract
Telah dilakukan penelitian dengan judul “ Uji Daya Hambat Ekstrak Kental Daun Kratom ( Mitragyna speciosa Korth ) Terhadap Pertumbuhan Bakteri Staphylococus aureus Sebagai Penyebab Jerawat. Penelitian ini bertujuan untuk mengetahui ada tidaknya daya hambat dan pada konsentrasi berapa ekstrak kental daun kratom dapat menghambat pertumbuhan bakteri, ekstrak kental daun kratom terhadap pertumbuhan bakteri Staphylococcus aureus. Pengujian daya hambat dilakukan dengan metode sumuran dengan perlakuan yang berbeda yaitu konsentrasi ekstrak 30%, 35%, 40%, 45%, 50%, kontrol positif ( antibiotik tetrasiklin ), dan kontrol negatif ( etanol 96% ). Hasil pengukuran rata-rata diameter daya hambat yaitu konsentrasi 30% sebesar 6,67 mm, 35% sebesar 7,31 mm, 40% sebesar 8,71 mm, 45% sebesar 9,38 mm, 50% sebesar 13,88 mm, kontrol positif sebesar 14,26 mm, dan kontrol negatif sebesar 0 mm. Hasil penelitian menunjukkan bahwa ekstrak etanol daun kratom mempunyai daya hambat terhadap pertumbuhan bakteri Staphylococcus aureus, dan ekstrak daun kratom sudah mampu mengahmbat pertumbuhan bakteri Staphylococcus aureus pada konsentrasi 30% dengan diameter daya hambat sebesar 6,67 mm.
