Buah Belimbing wuluh (Averrhoa bilimbi L.) biasanya digunakan oleh masyarakat sebagai obat jerawat secara tradisional sehingga pengobatannya kurang efektif dan efisien. Tujuan penelitian ini adalah untuk memformulasikan sediaan krim dari ekstrak etanol Buah Belimbing wuluh (Averrhoa bilimbi L.) dan untuk mengetahui mutu fisik dari sediaan krim yang dibuat dari ekstrak etanol buah belimbing wuluh (Averrhoa bilimbi L.). Desain penelitian ialah pre and post test design pada krim yang dibuat dengan 3 variasi pada emulgator Na. lauril sulfat 0,5%, 1% dan 2% yang diuji sebelum dan sesudah penyimpanan selama 12 hari. Hasil penelitian menunjukkan bahwa ekstrak etanol Buah Belimbing wuluh (Averrhoa bilimbi L.) dapat di formulasikan sebagai sediaan krim dan pada pengujian organoleptik, daya sebar, dan homogenitas terdapat 2 formula yang memenuhi syarat yaitu Na. lauril sulfat 0,5% dan 1%, dan pada pengujian pH tidak terdapat formula yang memenuhi syarat Kata kunci : Ekstrak Buah Belimbing wuluh, Mutu Fisik dan Na. lauril sulfat.
Fresh meat is one of the most perishable foodstuffs, hence, it is not stored for long. Therefore, preservation efforts to extend the shelf life are needed. Meanwhile, Wuluh Starfruit (Averrhoa bilimbi L.) is applicable as a natural preservative due to its anti-microbial activity to inhibit the growth and rate of meat's biochemical reactions. This research aims to determine the potential of Wuluh starfruit juice (Averrhoa bilimbi L.) as a natural preservative for fresh meat using the ALT method. The total plate number method was used in which the meat was soaked with Wuluh starfruit juice in a concentration of 50, 75, and 100%, meanwhile, water was used as a negative control. Furthermore, the meat was immersed for 12 hours, and then, the number of bacterial colonies that grew after incubation for 24 hours was counted. The results showed that at a concentration of 50, 75 and 100%, the number of plates obtained were 23x102, 14x102, and 88x101 colonies/g respectively. For negative water control, TBUD results were obtained, while the use of wuluh starfruit juice (Averrhoa bilimbi L.) suppressed the microbial growth in the meat hence, microbial activity in beef rot was inhibited. The higher the concentration of wuluh starfruit juice (Averrhoa bilimbi L.), the greater its potential as a natural preservative for fresh beef.
Gotu Kola (Centella asiatica (L.) Urb) is a plant widely grown and scientifically proven to be an antioxidant. This study makes a lotion formula containing dried Gotu kola herb with varying concentrations of emulgator span 60 and tween 60. It determines the concentration of span 60 and tween 60, producing lotions with the most stable physical quality and accelerated storage methods. The lotion was prepared using a concentration of Centellaasiatica (L.) Herbaceous Dry Herb extract of 1% and an Emulgator span 60 and tween 60 in a concentration variation of 5%, 7.5%, and 10%. The stability of the lotion was determined based on quality observations. The physical condition before and after the storage is accelerated for six cycles at a temperature of 5oC and 35oC in organoleptic, homogeneous, pH, viscosity, diffusion power, and emulsion type. The research results show the physical quality stability of formula I (5% emulgator) did not meet the requirements of the dispersion test before storage was accelerated. In contrast, the formula with a 7.5% emulgator met the physical quality requirements of the preparation before and after storage was accelerated. Additionally, the 10% emulgator did not meet the requirements of the dispersion test after accelerated storage. The type of emulsion in all three formulas is the M / A type. The most stable physical quality of the three preparations is a formula with a 7.5% emulgator.Keywords: Lotion, Gotu kola (Centella asiatica (L.) Urb), physical quality, span, and tween.Pegagan (Centella asiatica(L.)Urb) merupakan tanaman yang banyak tumbuh di Indonesia dan telah terbukti secara ilmiah memiliki kemampuan sebagai antioksidan. Penelitian ini bertujuan untuk membuat formula lotion yang mengandung sari kering herba pegagan (Centella asiatica(L.) Urban) dengan variasi konsentrasi emulgator span 60 dan tween 60, dan untuk mengetahui konsetrasi span 60 dan tween 60 yang menghasilkan lotion dengan mutu fisik yang paling stabil dengan metode penyimpanan dipercepat. Sediaan dibuat lotion dengan konsentrasi sari Kering Herba Pegagan (Centellaasiatica(L.) Urban ) sebesar 1% dan Emulgator span 60 serta tween 60 dengan variasi konsentrasi 5%, 7,5%, dan 10% kemudian stabilitas sedian lotion ditentukan berdasarkan pengamatan mutu fisik sebelum dans sesudah penyimpanan dipercepat selama 6 siklus pada suhu 5oCdan 35oC yang meliputi organeleptis, homogentias, pH, viskositas, daya sebar, dan tipe emulsi. Hasil penelitian pada pengujian kestabilan mutu fisik formula I (emulgator 5%) tidak memenuhi syarat pada uji daya sebar sebelum penyimpanan dipercepat, sedangkan Formula dengan emulgator 7,5% memenuhi persyaratan mutu fisik sediaan sebelum maupun sesudah penyimpanan dipercepat, dan formula dengan emulgator 10% tidak memenuhi syarat pada uji daya sebar setelah penyimpanan dipercepat, untuk tipe emulsi pada ketiga formula tersebut merupakan tipe emulsiM/A. Mutu fisik yang paling stabil dari ketiga sediaan tersebut adalah formula dengan emulgator 7,5%.Kata kunci : Lotion, herba pegagan (Centella asiatica (L.) Urb), mutu fisik, span dan tween.
