ABSTRAKDaun ketapang (Terminalia catappa L.) adalah tanaman yang sering dimanfaatkan oleh masyarakat sebagai tanaman obat tradisional. Penelitian ini dilakukan untuk mengetahui pengaruh ekstrak etanol daun ketapang warna hijau, warna merah, kombinasi daun warna hijau dan daun warna merah terhadap pertumbuhan bakteri Staphylococcus aureus. Penelitian ini bersifat eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan yaitu P0 (aquadest sebagai kontrol negatif), P1 (ekstrak etanol daun hijau), P2 (ekstrak etanol daun merah), dan P3 (kombinasi ekstrak etanol daun ketapang berwarna hijau dan merah) dan masing-masing 3 kali ulangan. Uji mikrobiologi menggunakan metode difusi. Berdasarkan hasil uji Anova menunjukkan bahwa ekstrak daun ketapang sangat berpengaruh terhadap pertumbuhan Staphylococcus aureus (P=0,000).Berdasarkan hasil uji lanjut Duncan rata-rata diameter zona hambat yang terbentuk menunjukkan bahwa kombinasi ekstrak daun ketapang warna hijau dan warna merah memiliki zona hambat yang lebih besar (30,92 mm) dan berbeda nyata dengan ekstrak daun ketapang berwarna hijau (21,92 mm), akan tetapi tidak berbeda nyata dengan ekstrak daun ketapang warna merah (26,42 mm).Dari hasil penelitian ini dapat disimpulkan bahwa ekstrak daun ketapang dapat menghambat pertumbuhan bakteri Staphylococcus aureus.Kata kunci: Terminalia catappa L., diameter zona hambat, Staphylococcus aureus Ketapang leaf (Terminalia catappa L.) is a plant that is often used by the community as a traditional medicinal plant.

The background of this study is Staphylococcus aureus is an anaerobic facultative bacterium and one of the normal microflora in the mouth. However, if it is influenced by predisposing factors, it will become a pathogen. Bidara leaves have antimicrobial activity against Staphylococcus aureus, because Bidara leaves contain various compounds including alkaloids, flavonoids, steroids, tannins and essential oils. The purpose of this study was to determine how much inhibitory power produced by Bidara leaf extract on the growth of Staphylococcus aureus bacteria. This research method is a laboratory experimental research using the diffusion test (wells) method. The sample of this study was Staphylococcus aureus. Dilution of Bidara leaf extract consists of 5 concentrations including: 20%, 40%, 60%, 80%, and 100%. Chlorampheniocol is used for Positive control while Negative control uses aquadest. Based on observations show that the average diameter of inhibitory zone Bidara leaf extract at a concentration of 20% with a diameter of 10.5 mm (R), at a concentration of 60% and 80% with a diameter of 16 mm and 18 mm (I), at a concentration of 100% with a diameter of 24 mm (S). It can be concluded that the higher the concentration of Bidara leaf extract, the inhibition zone formed will increase. So Bidara leaves are good for use in treating infections caused by Staphylococcus aureus bacteria.
