Merr .adalah enzim bromelain. Fungsi primer bromelain menguraikan protein dan bahan antibakteri. Mekanisme kerja bromelain sebagai antibakteri yaitu dengan cara menghambat enzim reverse transcriptase dan DNA topoisomerase. Tujuan penelitian menganalisis efektivitas daya antibakteri berbagai konsentrasi enzim bromelain dari ekstrak nanas terhadap Streptococcus mutans secara in-vitro. Metode: Jenis penelitian adalah eksperimental di laboratorium. Pengujian anti bakteri enzim konsentrasi 1, 2, 3, 4, 5, 6, 7, 8, 9, dan 10%, serta kontrol positif Ciprofloxacin cair 20mg terhadap Streptococcus mutans dengan metode difusi Kirby Bauer. Daya hambat antibakteri diukur dengan menggunakan jangka sorong. Penelitian dilakukan dua tahap, pertama melakukan ekstraksi enzim bromelain dari ekstrak nanas. Filtrat ekstrak kasar bromelain ditambahkan ammonium sulfat konsentrasi 40% dan dilakukan pengadukan selama 45 menit selanjutnya diinkubasi satu malam pada suhu 40C. Flitrat disaring dengan kertas Whatman no 1. Hasil endapan diliofilisasi dengan cara freeze dried. Tahap kedua dilakukan pengujian daya antibakteri berbagai konsentrasi enzim bromelain pada media Mueller Hinton Agar (MHA) yang telah ditumbuhi bakteri Streptococcus mutans hasil inkubasi selama 1x24 jam pada suhu 370C. Hasil: Enzim bromelain dapat menghambat bakteri Streptococcus mutans mulai dari konsentrasi 1%, diameter zona hambat sebesar 11 mm. Terjadi peningkatan yang signifikan pada konsentrasi 10%, diameter zona hambat sebesar 20 mm. Ciprofloxacin cair 20mg sebagai kontrol positif menunjukan daya hambat dengan  zona hambat 24 mm. Simpulan: Enzim dari ekstrak nanas memiliki daya antibakteri terhadap Streptococcus mutans yang dibuktikan dengan adanya zona hambat pada media MHA.Kata kunci: nanas; enzim bromelain; Streptococcus mutansABSTRACTIntroduction: One of the organic substances in the pineapple (Ananas comosus (L.) Merr.) is the bromelain enzyme. The primary function of bromelain is to break down proteins and antibacterial substances. The mechanism of action of bromelain as an antibacterial is by inhibiting the reverse transcriptase and DNA topoisomerase. The study aimed to analyse the effectiveness of the antibacterial activity of various concentrations of bromelain enzyme from pineapple extract against Streptococcus mutans in-vitro. Methods: This research was an experimental laboratory. Antibacterial enzyme testing with concentrations of 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10%, and positive control of 20 mg liquid Ciprofloxacin on Streptococcus mutans was performed using the Kirby Bauer diffusion method. The antibacterial inhibition was measured using a calliper. The research was carried out in two stages. The first was to extract the bromelain enzyme from pineapple extract.

These variations and changes can be seen and measured through panoramic radiographs. The purpose of this study was to examine the morphology and inclination of the articular eminence and the depth of the glenoid fossa based on age observed from a panoramic radiograph. Methods: This research was descriptive with a purposive sampling technique. The number of samples obtained using the Slovin formula, which resulted in 60 panoramic radiographs of the patients from Universitas Padjadjaran Dental Hospital (RSGM Unpad), during the period of January-May 2018, with an age range of 5-30 years, divided into three age groups based on the age of the temporal component growth. Eminence morphology and inclination, and fossa depth were measured using ImageJ software. The data were processed using Microsoft Excel® to determine the minimum, maximum, mean, and standard deviation values. Results: Most articular eminence morphology found in each age group were sigmoid. The mean articular eminence inclination in the age range of 5-10 years was 42°, 44° in the age range of 11-20 years, and 58° in the age range of 21-30 years. The mean of the glenoid fossa depth in the age range of 5-10 years was 4.62 mm, 5.71 mm in the age range of 11-20 years, and 7.52 mm in the age range of 21-30 years. Conclusions: Most articular eminence morphology during the growth period is sigmoid. The mean value of the articular eminence inclination and the glenoid fossa depth increases with age during the growth period.
