Water, one of the most important elements of the body and one of the macro substances, has the similar role as carbohydrates, fats and proteins for us humans. Humans cannot survive in few days without drinking. Toxins in human body can be cleansed by consuming water regularly. Infused water alternately becomes the another option to encourage people to drink much water. Furthermore, infused water can help out many people who do not have time or do not like eating fruits. However, many people do not drink water because of their personal reason although infused water might become the second opinion after pure water, and can increase an appetite because of the fruit color. Based on the reason above, the research purposes were appointed to examine the effect of the added date palm and soaking time towards the levels of anti-oxidant in apple-cinnamon infused water. The study was conducted using a Completely Randomized Design (CRD) factorial with 2 factors. In the first factor, the research media was added with dates (0, 10, and 20 grams), and the second factor, the media was measured from its soaking time (4, 8, and 12 hours). The research was initiated by creating of apple-cinnamon infused water with the aadditional various dates. Then, conducting various analyses like chemical analysis, total sugar content analysis, vitamin C, DPPH and FRAP antioxidant activity, total phenol, total solids, and pH. The optimum result was emerged when the additional 10 gram of dates and 4 hours of immersion time were combined. The characteristics of infused water are total sugar 24.37%, vitamin C 11.39 mg / 100 ml, 34.82% RSA DPPH, FRAP value 5.15%, total phenol 18.51 mg gallic acid / 100 ml, total solids 4.75oBrix, and the degree of acidity (pH) 5.65.

Issues about environmental damage caused by the presence of plastic-based packaging materials require the development of eco-friendly packaging materials. Breadfruit starch contains amylose which has the potential to be developed into natural packaging materials, or edible films. Another function of packaging was to protect food ingredients from damage, one of which was microbiological damage. This study aimed to determine the level of breadfruit starch to produce edible films that meet the standards and to determine the ability of cinnamon extract to inhibit the activity of tested bacteria. The study was conducted using a factorial completely randomized design with 2 factors, namely the concentration of breadfruit starch and the concentration of cinnamon. The results showed that breadfruit starch can be used at a level of 6% which will produce edible film with a tensile strength of up to 6.37 MPa and a thickness of 0.23 mm. Cinnamon extract were able to inhibit the growth of Escherichia coli and Staphylococcus aureus bacteria. Both breadfruit starch and cinnamon extract have the potential to be developed as natural ingredients in the process of making edible films.

Anthocyanin was a bioactive compound which has an anti-infl ammatory effect, anticancer, antimutagen, antioxidant, anticholesterol, and also acts as therapheutic agent for artherioschlerosis. Initial step for anthocyanin metabolism was hydrolyzed to anthocyanidin (aglikon) by β-D-glucosidase. Pediococcus pentosaceus N11.16 is known to be one of bacteria which has a capability to hydrolyze black glutinous rice anthocyanin extract. The aims of this research were to study the fermentative characteristics of MRS containing black glutinous rice anthocyanin medium (MRSm+Anthocyanin) using lactic acid bacteria P. pentosaceus N11.16. The results showed that P. pentosaceus N11.16 could grew well in this medium. Total acid producing bacteria increased untill 2 log cycle with antioxidant activity (%RSA) 75% and the Fe 3+ ion reducing capacity 36.75%. Phenolic compound in the MRSm+ anthocyanin was 584.05 mg asam galat/100 mL after being fermented for 16 hours. Phenolic compound in MRSm+anthocyanin medium were higher than MRSm or control medium (MRS). Beta glucosidase activities of the bacterial cell tend to be higher in theMRS anthocyanin medium than MRS without sugar and control medium.Keywords: Anthocyanin, black glutinous rice, lactic acid bacteria, antioxidant ABSTRAKLangkah awal dalam metabolisme antosianin, komponen bioaktif utama yang terdapat dalam beras ketan hitam, adalah hidrolisis menjadi antosianidin (aglikon) dengan memanfaatkan enzim β,D-glukosidase. Pediococcus pentosaceus N11.16 merupakan salah satu bakteri yang telah diisolasi dan teruji kemampuannya untuk menghidrolisis antosianinberas ketan hitam. Penelitian ini bertujuan untuk mempelajari karakteristik fermentatif medium fermentasi yang mengandung antosianin beras ketan hitam menggunakan bakteri asam laktat P. pentosaceus N11.16. Penelitian dilakukan dengan cara menguji kemampuan tumbuh isolat dalam medium MRS yang dimodifi kasi (MRSm) dengan penambahan antosianin beras ketan hitam. Hasil menunjukkan bahwa bakteri P. pentosaceus N11.16 mampu tumbuhdengan baik dalam medium MRS yang mengandung antosianin beras ketan hitam. Kenaikan mencapai 2 log cycle dengan aktivitas antioksidan (%RSA) mencapai 75% dan kemampuan menangkap logam mencapai 36,75%. Total fenol medium MRSm+antosianin mencapai 584,05 mg asam galat/100 mL medium setelah 16 jam fermentasi. Totalfenol medium MRSm+antosianin cenderung lebih tinggi daripada MRSm atau kontrol (MRS). Aktivitas enzim β glukosidase sel bakteri cenderung lebih tinggi pada medium MRSm+antosianin daripada MRSm atau kontrol (MRS).Kata kunci: Antosianin, beras ketan hitam, bakteri asam laktat, antioksidan
