Abstract
Biji salak pondoh (Salacca zalacca (Gaertn.) Voss) memiliki
aktivitas antibakteri terhadap S. aureus karena mengandung senyawa
flavonoid dan tanin. Emulgel adalah gabungan dari emulsi dan gel dengan
komponen utama HPMC sebagai gelling agent. Tujuan penelitian ini
adalah untuk mengetahui pengaruh variasi HPMC terhadap mutu fisik dan
stabilitas sediaan emulgel ekstrak biji salak pondoh dan mengetahui
senyawa kimia yang terdapat pada ekstrak biji salak pondoh sediaan
emulgel yang memiliki aktivitas antibakteri.
Ekstrak biji pondoh dibuat menggunakan metode maserasi dengan
pelarut etanol 96%. Ekstrak yang diperoleh dibuat 4 formula sediaan
emulgel dengan variasi konsentrasi HPMC 2%, 2,5%, 3% dan kontrol
negatif pada sediaan emulgel. Sediaan emulgel dilakukan uji mutu fisik
meliputi uji organoleptik, uji homogenitas, uji tipe emulgel, uji pH, uji
daya sebar, uji daya lekat, uji viskositas, uji stabilitas emulgel dan uji
aktivitas antibakteri terhadap zona hambat menggunakan metode sumuran
dengan media MHA. Data yang diperoleh diolah dengan statistik Analysis
of Variance (ANOVA).
Hasil penelitian menunjukkan bahwa pada ekstrak biji salak
pondoh dapat diformulasikan menjadi emulgel. Variasi konsentrasi HPMC
berpengaruh terhadap mutu fisik dan stabilitas sediaan emulgel terutama
pada uji viskositas, daya sebar dan daya lekat. Semua formula
menghasilkan mutu fisik dan stabilitas yang baik serta memenuhi
persyaratan. Hasil diameter zona hambat sediaan emulgel terbukti
memiliki aktivitas antibakteri yang tergolong kuat dalam menghambat
pertumbuhan bakteri Staphylococcus aureus dimana diameter paling
tinggi didapat 20,22 mm yang terdapat pada formula 1 dengan variasi
HPMC 2% hasil pengujian SPSS menunjukkan bahwa formula 1 tidak
memiliki perbedaan yang signifikan dengan kontrol positif dengan nilai
sig > 0,05.
Salak pondoh seeds (Salacca zalacca (Gaertn.) Voss) exhibits
antibacterial activity against S aureus due to its content of flavonoid and
tanin compounds. Emulgel is a combination of an emulsion and a gel,
with HPMC as the main gelling agent. The aim of this study was to
determine the effect of varying HPMC concentrations on the physical
quality and stability of salak pondoh seed extract emulgel, as well as to
identify the chemical compounds present in the emulgel formulation of
salak pondoh seed extract that exhibit antibacterial activity.
Salak pondoh seed extract was prepared using the maceration
method with 96% ethanol as the solvent. The obtained extract was
formulated into 4 emulgel preparations with varying HPMC
concentrations of 2%, 2.5%, 3%, and a negative control in the emulgel
formulation. The emulgel preparations underwent physical quality tests,
including organoleptic evaluation, homogeneity test, emulgel type test,
pH test, spreadability test, adhesion test, viscosity test, emulgel stability
test, and antibacterial activity test against inhibition zones using the well
diffusion method with MHA media. The collected data were analyzed
using Analysis of Variance (ANOVA) statistics.
The results of the study showed that salak pondoh seed extract
can be formulated into an emulgel. Variations in HPMC concentration
affected the physical quality and stability of the emulgel preparation,
especially in viscosity, spreadability, and adhesion tests. All formulas
produced good physical quality and stability, meeting the required
standards. The inhibition zone diameter results demonstrated that the
emulgel preparations exhibited strong antibacterial activity against the
growth of Staphylococcus aureus, with the largest diameter of 20.22 mm
observed in formula 1 with 2% HPMC concentration. SPSS analysis
showed that formula 1 did not have a significant difference compared to
the positive control, with a significance value of > 0.05.
