Dental plaque prevention can be achieved by inhibition of mouth cavity microbes to built biofilm. Kaempferia galanga rhizome has been known as a potential antibacterial agent. This research aimed to reveal the potency of Kaempferia galanga extract and essential oil as anti plaque active agents, based on their in vitro inhibitory activity against the planktonic growth and biofilm of Streptococcus mutans ATCC 21752. Kaempferia galanga extract was obtained by defatting dried-pulverized samples in petroleum ether prior to immersion in 70% ethanol. The fresh rhizome was steam-hydro distilled for 6 h to yield the essential oil. Antibacterial and anti biofilm assays were measured by micro dilution technique on polystyrene 96-wells micro titer plates at 37°C. The percentage of inhibition was calculated by comparing the absorbance of samples to the vehicle (control) measured by micro plate reader at 595 nm. Biofilms formed were first stained by 1% crystal violet. The above assays were performed in triplicates. This study revealed that both K. galanga rhizome essential oil and ethanolic extract showed antibacterial and antibiofilm activity towards S. mutans. The ethanol extract showed MIC90 value at 0.091% w/v and MBC at 2.724% w/v for antibacterial activity; IC50 at 0.048 % w/v for anti biofilm formation activity; and EC50 at 0.052%w/v for biofilm degradation activity. Until the highest concentration tested (0.6%w/v), the MIC90 and MBC values of the essential oil were not revealed, but higher biofilm inhibitory activity i.e. IC50 at 0.025 % w/v; and EC50 at 0.034 %w/v were observed. Key words: biofilm inhibitor, antibacterial, Kaempferia galanga

<p>ABSTRAK<br />Kencur (Kaempferia galanga) banyak dimanfaatkan oleh rumah<br />tangga, industri obat maupun makanan serta minuman dan industri rokok<br />kretek. Peningkatan pemakaian simplisia kencur dalam berbagai industri di<br />dalam negeri akan meningkatkan konsumsi simplisia ini, sehingga upaya<br />peningkatan produksi masih perlu dilakukan melalui budidaya, di<br />antaranya dengan penggunaan varietas unggul yang didukung dengan<br />pemupukan yang optimal. Di dalam penelitian ini dikaji respon lima<br />nomor unggul kencur terhadap paket pemupukan organik dan anorganik<br />pada tanah latosol di dataran rendah, Cileungsi, Bogor, Jawa Barat.<br />Penelitian dilaksanakan mulai bulan Oktober 2003 sampai Agustus 2004,<br />dengan RAK dalam pola faktorial. Faktor I nomor unggul kencur (V1, V2,<br />V3, V4 dan V5) dan faktor II paket pemupukan (6 paket), diulang 2 kali.<br />Jarak tanam yang digunakan 20 x 20 cm, ukuran petak 4 x 1,2 m. Hasil<br />penelitian menunjukkan, empat nomor unggul kencur (V1, V3, V4, V5),<br />dari lima nomor yang diuji, mempunyai kemampuan untuk menghasilkan<br />rimpang segar dan kering yang sama, dengan kisaran bobot rimpang segar<br />62,27-70,22 g/tanaman dan kisaran bobot rimpang kering 16,95-19,33 g/<br />tanaman. Paket pemupukan yang dianjurkan untuk semua nomor yang<br />diuji adalah pupuk kandang 20 ton/ha + urea 250 kg/ha + SP36 200 kg/ha<br />+ KCl 200 kg/ha, atau pemupukan organik dengan pupuk kandang kerbau<br />40 ton/ha. Respon lima nomor unggul kencur terhadap aplikasi paket<br />pemupukan memberikan mutu dengan hasil yang berbeda, yaitu kadar<br />minyak atsiri V3 (2,03%) tergolong mutu I, sedangkan empat nomor<br />lainnya tergolong mutu II (1,08 -1,97%), dengan hasil minyak atsiri 0,325<br />– 0,466 ml/tanaman. Serapan hara lima nomor unggul kencur terhadap<br />paket teknologi yang diuji memperlihatkan, serapan hara N berkisar antara<br />149,60 – 415,60 mg/tanaman, hara P 41,50 – 112,50 mg/tanaman, hara K<br />236,10 – 571,70 mg/tanaman.<br />Kata kunci : Kencur, Kaempferia galanga, varietas unggul, pemupukan,<br />serapan hara, produksi, mutu</p><p><br />ABSTRACT<br />Response of five galanga promising lines to fertilization<br />India galanga (Kaempferia galanga) is commonly used for<br />household consumption, medicines, food and drink supplement industries<br />as well as cigarette sauce. Increase in demand of this commodity for<br />domestic industries will raise the consumption of symplicia. Therefore,<br />effort in increasing yield of the plant through cultivation technique<br />improvement, i.e. application of superior variety and fertilization, is worth<br />to be accomplished. In this experiment five Galanga promising lines of<br />India galanga were subjected to organic and inorganic fertilizations at<br />low land latosol soil, Cileungsi, Bogor, West Java. Experiment was carried<br />out from October 2003 – August 2004 and arranged in randomized block<br />in factorial design, with two replications. First factor is the promising lines<br />(V1, V2, V3, V4 and V5); factor II is fertilization packages (6 packages).<br />Plot size of 4 x 1.2 m and plant spacing of 20 x 20 cm, were applied. The<br />results showed that four of five tested promising lines yielded the same<br />results of fresh and dry weight of rhizomes ranged from 62.27-70.22<br />g/plant, and the dry weight was 16.95-19.33 g/plant respectively.<br />Fertilization packages of dung manure 20 t/ha + urea 250 kg/ha + SP36<br />200 kg/ha + KCl 200 kg/ha, or organic fertilizer by using dung manure 40<br />ton/ha, are recommended. Application of fertilization package resulted in<br />different response to the plant for their qualities. The essential oil content<br />of promising lines V3 belongs to the first grade of quality (2.03%), while<br />the others are the second one (1.08-1.97%), with the yield of essential oil<br />ranged from 0.325 – 0.466 ml/plant. The nutrients uptake of the promising<br />lines to the applied technology package were 149.60 – 415.60 mg/plant of<br />N, 41.50 – 112.50 mg/plant of P, and 236.10 – 571.70 mg/plant of K<br />nutrients.<br />Key words: Kaempferia galanga , superior variety, fertilization, nutrient<br />up take, yield, quality</p>

Aromatic ginger (Kaempferia Galanga L.) is a spice plant that has a high volatile content with active compounds of ethyl p-methoxy cinnamate (23.65%) and ethyl cinnamate (5.98%). These two compounds have been reported to have antibacterial activity against Streptococcus pyogenes and Staphylococcus aureus, which are two types of bacteria that can cause sore throat. The application of aromatic ginger essential oil on hard candy can potentially reduce inflammation in the throat. This study aims to determine the effect of aromatic ginger essential oil concentration on hard candy in inhibiting the growth of Streptococcus pyogenes and Staphylococcus aureus bacteria and to determine their acceptance by the panelists. This research was conducted with 6 treatments of variations in the concentration of aromatic ginger essential oil, including 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1%. The results showed that the higher the concentration of aromatic ginger essential oil on hard candy would further increase the inhibition of the growth of Streptococcus pyogenes and Staphylococcus aureus bacteria. The highest inhibitory activity and the highest panelist acceptance was 1% essential oil concentration with 3.29% moisture content, 0.12% ash content, and 7.13% reducing sugar. The use of aromatic ginger essential oil on hard candy as a flavoring and well as inhibiting the growth of strep throat-causing bacteria (Streptococcus pyogenes and Staphylococcus aureus) has the potential to be developed. Keywords: Antibacterial, hard candy, aromatic ginger, essential oil, Streptococcus pyogenes, Staphylococcus aureus
