Abstract

Coffee drinks are one of the most popular drinks for people of all ages, especially adults. But now with the addition of flavor, most people are enjoying coffee drinks.The purpose of the study was to see the effect of fermentation on the taste and aroma of brewed Arabica coffee with Lactobacillus casei and yeast Saccharomyces cerevisiae isolates with the addition of grape juice and sucrose and the level of toxicity of the fermentation of brewed Arabica coffee with the Brine Shrimp Lethality Test (BSLT).This research is experimental, namely the fermentation of brewed Arabica coffee with Lactobacillus casei and yeast Saccharomyces cerevisiae isolates with the addition of grape juice and sucrose. Fermentation was carried out for 3 days at open room temperature under anaerobic conditions. The results of the fermentation were tested for Brine Shrimp Lethality Test (BSLT), alcohol content test and organoleptic test by 15 panelists. Furthermore, the data were tested using the hedonic test of analysis of variance.The results of the variance showed that the fermentation of roasted Arabica coffee and green beans on taste obtained F count < F table 1% showed no significant difference, for aroma obtained F count > F table 1% showed there was a significant difference, to the color of the steeped fermented sample Roasted Arabica coffee obtained F count < F table 1% shows there is no real difference while in green beans obtained F count > F table 1% shows there is a significant difference.

Abstract

Kopi mengandung polyphenol sebagai senyawa antioksidan. Kandungan yang terdapat pada temu giring adalah senyawa alkaloida, flavonoida, triterpenoida, saponin dan tanin sebagai antioksidan. Jahe mengandung gingerol, beta-caroten, asam mengandung gingerol, beta-caroten, asamkafeat, curc kafeat, curcumin sebagai antioksidan. Tujuan dari p umin sebagai antioksidan. Tujuan dari penelitian enelitian ini adalah untuk mengetahui apakah minuman kopi yang dikombinasikan dengan ekstrak jahe ( Zingiber officinale) dan ekstrak temu giring (Curcuma heyneana) memiliki kapasitas antioksidan dan disukai oleh sukarelawan. Penelitian ini secara eksperimental dalam menyiapkan minuman kopi yang menggabungk menggabungkan ekstrak jahe ekstrak jahe dan ekstrak temu ekstrak temu giring dan giring dan mendemonstrasi mendemonstrasikan penemuan simplisia, penemuan simplisia, produksi produksi ekstrak ekstrak jahe dan temu giring, giring, serta optimasi optimasi formula formula menggunaka menggunakan SLD ( simplex simplex lattice lattice design) dan melakukan survey survey responden responden pada setiap formula. Rendemen simplisia jahe 500 g dan temu giring 750 g giring 750 g dengan berat ekstrak jahe sebanya dengan berat ekstrak jahe sebanyak 88,8 g k 88,8 g dan berat ekstrak temu giring sebanyak 98, dan berat ekstrak temu giring sebanyak 98,2 g. Penentuan optimasi formula menggunakan SLD didasarkan pada aktivitas antioksidan formula yang optimal, yaitu rasio jahe : temu giring (1/4 : optimal, yaitu rasio jahe : temu giring (1/4 : 3/4) formula II dan hasil formula II dan hasil hedonist masing-masing formula adalah formula IV dengan rasio jahe : temu giring (3/4 : 1/4)

Abstract

Background: Hydrogel mask is a type of preventive cosmetic, to prevent skin problems, protect and maintain the skin. Hydrogel eye mask is a type of eye mask with easy to stick and remove use, providing a cooling sensation around the skin around the eye area. Aloe vera  gel (Aloe vera  (L.) Burm.f.) can moisturize and brighten the skin, and contains secondary metabolite compounds that inhibit the tyrosinase enzyme. Objective: This study aims to formulate Aloe vera  gel (Aloe vera  (L.) Burm.f.) in the form of a hydrogel eye mask as a brightening using a skin analyzer. Method: This study used an experimental method with concentrations of 0% (blank), 0,5% (F1), 1% (F2), and, 1,5% (F3). Result: Phytochemical screening of Aloe vera  gel (Aloe vera  (L.) Burm.f), irritation test, physical evaluation of the preparation before the cycling test, namely homogeneity, elasticity, adhesiveness, and after the cycling test, namely organoleptic and pH, as well as effectiveness as a brightening using a skin analyzer. The results of 200 mL of Aloe vera  gel extract (Aloe vera  (L.) Burm.f.) contain alkaloids, flavonoids, saponins, tannins, glycosides, and steroids/triterpenoids. The preparation does not cause irritation, and is homogeneous. Blank elasticity:30,11%, F1:31,58%, F2:32,99%, and F3:33,67% with the condition 30-115%. Blank adhesion:6,13 seconds, F1:7,19 seconds, F2:9,18 seconds, and F3:12,11 seconds with the condition >4 seconds. After the cycling test there was no change in color, odor, and shape. pH Blank:6,43, F1:6,41, F2:6,14, and F3:6,10 with the requirement of 4,5-6,5 and the brightening effectiveness test on the skin analyzer experienced an increase in recovery of 32,59% in water content, elasticity of 36,81%, and a decrease in melanin of 29,87% for 4 weeks and the best formula is F3.  Conclusion: Aloe vera  gel extract (Aloe vera  (L.) Burm.f.) can be formulated into a hydrogel eye mask preparation with good physical quality and does not cause irritation.
