Perbandingan Efektivitas Ekstrak Sereh dengan Temulawak dalam Menghambat Pertumbuhan Streptococcus Mutans

Introduction; Streptococcus mutans is the main pathogenic bacteria that cause caries, caries treatment can be done traditionally with medicinal plants, including lemongrass and ginger. Aim; determine the comparison of the effectiveness of citronella leaf extract with ginger extract against Streptococcus mutants. Method; metabolic experimental research with a posttest-only control group design. Data collection by measuring the diameter of the zone of inhibition using shear calipers. Data were analyzed using a one-way ANOVA test. Results; showed that the average inhibitory diameter of 20% citronella extract was 12.00 ± 0.23, and 20% ginger extract was 9.00 ± 0.27 in inhibiting the growth of Streptococcus mutans, while the negative control (DMSO) had no inhibition. The conclusion is that there is a difference in the effectiveness of 20% citronella extract (Cymbopogon nardus) and 20% Curcuma (Curcuma xanthorrhiza) in inhibiting the growth of Streptococcus mutants.Pendahuluan; streptococcus mutans merupakan bakteri patogen utama penyebab karies, pengobatan karies dapat dilakukan secara tradisional dengan tanaman obat, antara lain sereh dan jahe. Tujuan;  mengetahui perbandingan efektivitas ekstrak daun serai wangi  dengan ekstrak jahe terhadap Streptococcus mutans. Metode; penelitian eksperimental metabolik dengan desain posttest-only control group design. Pengumpulan data dengan mengukur diameter zona hambat menggunakan kaliper geser. Data dianalisis dengan menggunakan uji ANOVA satu arah. Hasil; menunjukkan bahwa diameter hambat rata-rata ekstrak serai wangi 20% adalah 12,00 ± 0,23, dan ekstrak jahe 20% adalah 9,00 ± 0,27 dalam menghambat pertumbuhan Streptococcus mutans, sedangkan kontrol negatif (DMSO) tidak terdapat hambatan. Kesimpulan bahwa terdapat perbedaan efektifitas ekstrak serai wangi (Cymbopogon nardus) 20% dan temulawak (Curcuma xanthorrhiza) 20% dalam menghambat pertumbuhan mutan Streptococcus
