UJI AKTIVITAS ANTIBAKTERIEKSTRAK METANOL KULIT PISANG HIJAU LUMUT (Musa x paradisiaca L.) TERHADAP BAKTERI Staphylococcus aureus dan Escherichia coli SERTA IDENTIFIKASI GOLONGAN SENYAWAMETABOLIT SEKUNDER

Abstract: Kulit Pisang Hijau Lumut (Musa x paradisiaca L.) merupakan limbah organik yang masih belum banyak dimanfaatkan. Penelitian ini bertujuan untuk menentukan Konsentrasi Hambat Minimum (KHM) dan Konsentrasi  Bunuh Minimum (KBM) ekstrak metanol Kulit Pisang Hijau Lumut terhadap bakteri Staphylococcus aureus dan Escherichia coli, serta mengetahui golongan senyawa metabolit sekundernya. Ekstraksi dilakukan dengan metode maserasi, uji aktivitas antibakteri dilakukan dengan metode sumur difusi agar, dan skrining fitoki… Show more

“…The antibacterial mechanism is still unclear and it is suspected that the bacterial cell wall membrane is one of the places of action by interacting on the lipophilic side of the cell wall membrane, causing damage to the cell wall membrane [47]. Rita et al [54] stated that Pecah Seribu bananas have flavonoid and phenolic content of 2033.53 mg QE/100 g and 250.25 mg GAE/100 g respectively can inhibit the growth of Staphylococcus aureus bacteria by 12.27 mm at a concentration of 20 % and 13.60 mm at a concentration of 50 %, while Escherichia coli bacteria by 11.87 mm at a concentration of 20 % and 12.73 mm at a concentration of 50 %. The difference in sensitivity between fruit extract, flesh extract and unripe fruit peel extract of banana Kayu is due to the difference in the content of secondary metabolites contained.…”

“…Yanti (2020) melaporkan bahwa ekstrak n-heksana KPHL pada konsentrasi 20% mampu menghambat perkembangan S. aureus dan E. coli dengan daya hambat sebesar 11,00 serta 10,50 mm. Resaputra (2020) juga melaporkan bahwa ekstrak n-heksana kulit pisang seribu dapat menghambat pertumbuhan S. aureus dan E. coli yaitu masing-masing sebesar 10,5 mm. Keaktifan antibakteri ekstrak n-heksana dari ketiga kulit pisang tersebut kemungkinan disebabkan adanya senyawa-senyawa non polar baik asam-asam lemak, gliserida, dan lemak tidak tersabunkan seperti terpenoid, dan steroid.…”

“…Penelitian berbagai macam kulit pisang yang tumbuh di Bali menunjukkan bahwa ekstrak metanol kulit pisang hijau lumut mempunyai potensi sebagai antibakteri, sehingga bisa digunakan sebagai bahan dasar kesehatan kulit (Rita et al, 2020). Ekstrak tersebut menekan perkembangan bakteri S. aureus dan E. coli dengan Konsentrasi Hambat Minimum (KHM) berturut-turut sebesar 8% dan 10% (Rita et al, 2021). Berdasarkan kandungan dan khasiatnya, KPHL berpotensi untuk dikembangkan menjadi masker gel.…”
