Description Avocado leaves (Percea americana mill) are a part of avocado plants that have benefits as traditional medicines. Avocado leaves are potentially used as anti-diarrhea based on the content of chemicals contained therein, namely saponins, alkaloids, tannins, flavanoids, polyphenols, quercetin which are used to kill pathogenic bacteria, one of which is Escherichia coli. Escherichia coli is an opportunist germ that is commonly found in the human intestine as a normal flora. The purpose of this study was to determine the inhibition of avocado leaf extract on the growth of Escherichia coli bacteria. This type of research is an Experimental laboratory. The research design used in this study was static group comparison because this study was conducted to see differences in concentrations of 10%, 15%, 25%, 50% and 75% of avocado leaf extract in inhibiting the growth of Escherichia coli bacteria by looking at the clear zone formed. The results showed that at a concentration of 25%, 50% and 75% a clear zone (inhibition zone) was formed, whereas at concentrations of 10% and 15% no clear zone (inhibition zone) was formed. From the results of this study it can be concluded that avocado leaf extract can inhibit the growth of Escherichia coli at concentrations of 25%, 50% and 75%.
Daun alpukat (Percea americana mill) adalah bagian dari tanaman alpukat yang memiliki manfaat sebagai obat tradisional. Daun alpukat berpotensi digunakan sebagai anti-diare berdasarkan kandungan bahan kimia yang terkandung di dalamnya, yaitu saponin, alkaloid, tanin, flavanoid, polifenol, quercetin yang digunakan untuk membunuh bakteri patogen, salah satunya adalah Escherichia. Escherichia adalah kuman oportunis yang umumnya ditemukan di usus manusia sebagai flora normal. Tujuan dari penelitian ini adalah untuk menentukan penghambatan ekstrak daun alpukat pada pertumbuhan bakteri Escherichia. Jenis penelitian ini adalah laboratorium Eksperimental. Desain penelitian yang digunakan dalam penelitian ini adalah perbandingan kelompok statis karena penelitian ini dilakukan untuk melihat perbedaan konsentrasi 10%, 15%, 25%, 50% dan 75% ekstrak daun alpukat dalam menghambat pertumbuhan bakteri Escherichia dengan melihat zona jelas terbentuk. Hasil penelitian menunjukkan bahwa pada konsentrasi 25%, 50% dan 75% zona yang jelas (zona penghambatan) terbentuk, sedangkan pada konsentrasi 10% dan 15% tidak ada zona yang jelas (zona penghambatan) terbentuk. Dari hasil penelitian ini dapat disimpulkan bahwa ekstrak daun alpukat dapat menghambat pertumbuhan Escherichia pada konsentrasi 25%, 50% dan 75%.
