Abstract
Daun bidara arab (Ziziphus spina-christi L.) mengandung
senyawa yang dapat memiliki aktivitas antibakteri terhadap
Propionibacterium acnes yang merupakan bakteri penyebab jerawat.
Emulgel merupakan sediaan yang praktis. Salah satu komponen yang
dapat mempengaruhi sifat fisik dan stabilitas emulgel adalah gelling
agent. Gelling agent yang banyak digunakan adalah carbopol 940.
Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri emulgel
ekstrak etanol daun bidara arab terhadap Propionibacterium acnes dan
pengaruh variasi konsentrasi gelling agent carbopol 940 terhadap mutu
fisik dan stabilitas emulgel.
Ekstrak etanol daun bidara arab dibuat dengan metode maserasi
menggunakan etanol 96%. Emulgel dibuat menggunakan gelling agent
carbopol 940 dengan variasi konsentrasi 1; 1,25; dan 1,5%. Emulgel
dilakukan evaluasi mutu fisik diantaranya organoleptik, homogenitas,
pH, daya lekat, daya sebar, viskositas, dan tipe emulgel. Aktivitas
antibakteri sediaan emulgel dilakukan pengujian dengan metode difusi
sumuran. Hasil semua data yang diperoleh dilakukan analisis
menggunakan metode One-way ANOVA, Post Hoc, dan Paired�Samples T Test.
Hasil penelitian menunjukkan bahwa emulgel ekstrak etanol
daun bidara arab dengan variasi konsentrasi gelling agent carbopol
940 1; 1,25; dan 1,5% menghasilkan mutu fisik yang baik dan stabil
serta memiliki aktivitas antibakteri terhadap Propionibacterium acnes
dengan hasil berturut-turut yaitu 16,08; 15,08; dan 13,58 mm. Formula
I dengan konsentrasi carbopol 1% memiliki mutu fisik, stabilitas, dan
aktivitas antibakteri yang paling baik.
Arabic bidara leaves (Ziziphus spina-christi L.) contain
compounds that can have antibacterial activity against
Propionibacterium acnes which is the bacteria that causes acne.
Emulgel is a practical preparation. One component that can influence
the physical properties and stability of emulgel is gelling agent. The
gelling agent that is widely used is carbopol 940. This study aims to
determine the antibacterial activity of the emulgel from the ethanol
extract of bidara arab leaves against Propionibacterium acnes and the
effect of variations in the concentration of the gelling agent carbopol
940 on the physical quality and stability of the emulgel.
The ethanol extract of arabic bidara leaves is made by the
maceration method using 96% ethanol. Emulgel was made using the
gelling agent carbopol 940 with varying concentrations of 1; 1.25; and
1.5%. Emulgel was evaluated for physical quality including
organoleptic, homogeneity, pH, adhesive power, spreadability,
viscosity, and type of emulgel. The antibacterial activity of the emulgel
preparation was tested using the well diffusion method. The results of
all data obtained were analyzed using the One-way ANOVA, Post Hoc,
and Paired-Samples T Test methods.
The results of the research showed that the emulgel of ethanol
extract of Arabic bidara leaves with varying concentrations of the
gelling agent carbopol 940 1; 1.25; and 1.5% produces good and stable
physical quality and has antibacterial activity against
Propionibacterium acnes with results respectively, namely 16.08;
15.08; and 13.58 mm. Formula I with a carbopol concentration of 1%
has the best physical quality, stability and antibacterial activity.
