Lulur merupakan salah satu sediaan kosmetik tradisional yang digunakan untuk
mengangkat sel kulit mati sekaligus menjaga kesehatan kulit. Beras ketan hitam
(Oryza sativa L. var. glutinous) diketahui kaya antosianin dan amilopektin yang
berfungsi sebagai eksfolian alami, sedangkan wortel (Daucus carota L.)
mengandung -karoten dan vitamin E yang berperan sebagai antioksidan dan
pelembap kulit. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi
scrub beras ketan hitam dan sari wortel dalam formulasi krim lulur terhadap
stabilitas mutu fisik sediaan. Metode penelitian dilakukan secara eksperimental
dengan merancang 13 formula, yaitu basis krim (F0), variasi konsentrasi scrub
beras ketan hitam (F1F3), variasi konsentrasi sari wortel (F4F6), serta kombinasi
keduanya (F7F12). Evaluasi mutu fisik dilakukan melalui uji organoleptik,
homogenitas, pH, viskositas, tipe krim, daya tercuci, stabilitas sentrifugasi, serta uji
penyimpanan suhu ruang dan metode freeze and thaw. Hasil penelitian
menunjukkan bahwa seluruh formula memenuhi kriteria stabilitas fisik dasar tanpa
terjadi pemisahan fase. Penambahan scrub beras ketan hitam memengaruhi warna
menjadi abu kehitaman serta menyebabkan pengendapan partikel pada uji
sentrifugasi, terutama pada konsentrasi tinggi. Sementara itu, sari wortel
memberikan warna jingga alami dan meningkatkan viskositas krim, sehingga
memperbaiki kestabilan krim. Kombinasi keduanya menghasilkan variasi
organoleptik yang menarik dengan stabilitas fisik yang masih dapat diterima.
Kombinasi scrub beras ketan hitam dan sari wortel dapat diformulasikan menjadi
krim lulur dengan mutu fisik stabil, sediaan krim lulur yang memiliki stabilitas
paling baik adalah F9 (kombinasi scrub beras ketan hitam 10% dan sari wortel 10%)
selama masa pengujian cenderung stabil, meskipun diperlukan penambahan agen
suspensi untuk memperbaiki homogenitas distribusi butiran scrub.

Body scrub is a traditional cosmetic preparation used to remove dead skin cells
while maintaining skin health. Black glutinous rice ( Oryza sativa L. var. glutinous)
is known to be rich in anthocyanins and amylopectin which function as natural
exfoliants, while carrots ( Daucus carota L.) contain -carotene and vitamin E
which act as antioxidants and skin moisturizers. This study aims to determine the
effect of the combination of black glutinous rice scrub and carrot juice in a body
scrub cream formulation on the physical quality stability of the preparation. The
research method was carried out experimentally by designing 13 formulas, namely
cream base (F0), variations in black glutinous rice scrub concentration (F1F3),
variations in carrot juice concentration (F4F6), and a combination of both (F7
F12). Evaluation of physical quality was carried out through organoleptic tests,
homogeneity, pH, viscosity, cream type, washability, centrifugation stability, and
room temperature storage tests and freeze and thaw methods . The results showed
that all formulas met the basic physical stability criteria without phase separation.
The addition of black glutinous rice scrub affected the color to blackish gray and
caused particle sedimentation in the centrifugation test, especially at high
concentrations. Meanwhile, carrot juice provided a natural orange color and
increased the viscosity of the cream, thereby improving the stability of the cream.
The combination of the two produced interesting organoleptic variations with
acceptable physical stability. The combination of black glutinous rice scrub and
carrot juice can be formulated into a scrub cream with stable physical quality, the
scrub cream preparation that had the best stability was F9 (a combination of 10%
black glutinous rice scrub and 10% carrot juice) during the test period tended to
be stable, although the addition of a suspending agent was needed to improve the
homogeneity of the scrub granule distribution.
