EFEK ANTIBAKTERI EKSTRAK DAUN RUI (Harrisonia perforata Merr.) TERHADAP BAKTERI Pseudomonas aeuroginosa
No full textABSTRAK
Latar Belakang : Salah satu tumbuhan yang dapat dimanfaatkan sebagai obat herbal adalah Harrisonia perforata Merr yang dapat dijumpai di daerah tropis. Di Sulawesi Tengah khususnya kota Palu, Harrisonia perforata Merr dikenal masyarakat lokal dengan nama Rui. Bremmer (1992) melaporkan bahwa tumbuhan ini mempunyai aktivitas antimalaria, serta mengandung senyawa Omenthylalloptaeroxylin, perforatic acid, limonoid dan perforatin. Angka kematian akibat infeksi oleh bakteri Pseudomonas aeruginosa diduga mencapai 50%, tergantung dengan jenis infeksi.
Tujuan : Untuk mengetahui efek antibakteri ekstrak daun Rui (Harrisonia perforata Merr) terhadap bakteri Pseudomonas aeruginosa.
Metode : Jenis penelitian ini adalah eksperimental posttest control group only design dengan pengujian aktivitas antibakteri menggunakan metode difusi agar dengan mengukur zona hambat yang terbentuk. Konsentrasi ekstrak daun rui yang diiuji adalah 10%, 25%, 40%, dan 65% dengan Levofloxacin sebagai kontrol positif dan akuades kontrol negatif. Masing-masing perlakuan direplikasi sebanyak empat kali.
Hasil : Hasil penelitian menunjukkan bahwa ekstrak daun rui (Harrisonia perforata Merr.) dapat menghambat pertumbuhan bakteri Pseudomonas aeruginosa pada semua konentrasi yang diujikan. Dari hasil ini diperoleh nilai kadar hambat minimal (KHM) adalah 10%. Hasil uji statistik dengan menggunakan one-way ANOVA didapatkan nilai signifikasi p < 0,05 yang berarti terdapat perbedaan signifikan pengaruh ekstrak daun rui yang diberikan kepada bakteri Pseudomonas aeruginosa.
Kesimpulan : Ekstrak daun rui (Harrisonia perforata Merr.) memilki efek antibakteri terhadap bakteri Pseudomonas aeruginosa.

ABSTRACT
Background: One of the plants that can be used as an herbal remedy is Harrisonia perforata Merr, which can be found in the tropical areas. In Central Sulawesi, particularly in Palu city, Harrisonia perforata Merr is also known as Rui by the local citizens. Bremmer (1992) reported that this plant have anti malarial activity, as well as compounds containing O-menthylalloptaeroxylin, perforatic acid, limonoid and perforatin. Death rate due to the infection by bacterias is 50%, depending on the type of infection, respectively.
Objective: To determine antibacterial effect in Rui leaf extract (Harrisonia perforata Merr) against Pseudomonas aeruginosa.
Methods: This study is a posttest control group only experimental design by using agar diffusion method for anti bacterial activity test and measure the inhibition area. The concentration extract of Rui leaf that tested were 10%, 25%, 40%, 65%, with Levofloxacin as a positive control and distilled water as a negative control. Each the concentration was replicated four times.
Results: The results showed that the extraxt of Rui leaf (Harrisonia perforata Merr.) may inhibit the growth of Pseudomonas aeruginosa in all concentration tested. Results obtained value of the minimum inhibitory concentration (MIC) was 10%. Results of statistical test by using one-way ANOVA significance value of
EFEK ANTIBAKTERI EKSTRAK DAUN RUI (Harrisonia perforata [Blanco] Merr.) TERHADAP BAKTERI Citrobacter freundii

Latar Belakang: Di tengah banyaknya jenis obat modern di pasaran, terdapat kecenderungan global untuk kembali ke alam. Salah satu tumbuhan yang dapat dimanfaatkan sebagai obat herbal adalah Harrisonia perforata (Blanco) Merr., yang dikenal masyarakat Sulawesi Tengah dengan nama Rui. Tumbuhan ini mengandung senyawa fenolik, alkaloid, flavonoid, saponin, dan tanin yang memiliki aktivitas antibakteri. Citrobacter spp. termasuk bagian mikroflora intestinal manusia dan hewan. Dalam genus ini, Citrobacter freundii merupakan bakteri yang paling sering diisolasi dan spesies yang paling resisten antibiotik. Spesies Citrobacter muncul sebagai patogen nosokomial penting, menyebabkan diare dan infeksi lain pada manusia.
Metode: Desain penelitian ini adalah eksperimental laboratorium murni (true experiment) dengan rancangan eksperimen sederhana (posttest only with control group design). Metode ekstraksi yang digunakan adalah metode maserasi. Pengujian aktivitas antibakteri menggunakan metode difusi agar (metode sumur) dengan konsentrasi ekstrak 10%, 25%, 40%, dan 65%, amikasin 2% sebagai kontrol positif dan Na-CMC 1% sebagai kontrol negatif. Masing-masing perlakuan direplikasi sebanyak enam kali.
Hasil: Ekstrak daun Rui dapat menghambat pertumbuhan Citrobacter freundii pada konsentrasi 10%, 25%, 40%, dan 65%. Dari hasil ini diperoleh nilai Kadar Hambat Minimal (KHM) adalah 10% (9,45 mm). Hasil uji statistik menggunakan One Way ANOVA didapatkan nilai signifikansi

The trombone as portrayed in Portuguese iconography during the sixteenth and early seventeenth centuries
No full textThis article studies eleven sixteenth and seventeenth century iconographical sources depicting slide brass instruments, by both Portuguese and foreign artists active in Portugal, as well as foreign artists depicting Portuguese scenes. This study addresses questions concerning aspects of trombone technique that have not previously been considered and may have implications in the way the trombone was understood elsewhere in Europe. It focuses on aspects of technique depicted that may be representative of the trombone’s contemporary design and performance and therefore the manner in which the instrument was held and indeed played. Finally, this article suggests a transitional technical period when the way of holding the single-slide trumpet may have been used to play the trombone.Publisher PD
