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.

Based on interviews with a partner, the following community partner issues were lack of medicinal plants gardens around the Al Mubarak Sudiang Islamic boarding school, lack of knowledge and introduction to the types of plants with medicinal properties, and lack of knowledge about the health benefits of medicinal plants. Using traditional medicinal plants is the community's active participation in solving health problems. The community service partner were students in Al Mubarak boarding school. The solution to overcome the partner's problems was empowerment with a participatory learning approach emphasizing learning through consultation, training, coaching, and demonstration/simulation of medicinal plant cultivation and utilization. Then, the authors evaluated program implementation and sustainability before and after activities. The evaluation showed increased achievement levels in all success indicators. Thus, this community service had significant benefits for all participants. In conclusion, the empowerment of students in Al Mubarak Sudiang Islamic Boarding School can increase their knowledge in medicinal plants cultivation and utilization, skills in medicinal plants cultivation, and medicinal plants utilization. The local government should support and participate in the sustainability of this community service through small industries producing healthy drinks from medicinal plants.
