This research is an experimental study that aims to make a cookies formulation of tempeh flour substituted with red bit flour. The experimental design used was a completely randomized design with subtitution of red bit flour to tempeh flour cookies with different concentrations. The process of making cookies includes mixing flour, mixing margarine, egg, refined sugar then process to mixer, molding, and baking using the oven. The organoleptic test (preference) involved 30 semi-trained panelists. Tempe flour cookies with substitution of red bit flour with 4 formulations, formulation 1 with 0% concentration (control), formulation 2 with 12% substitution of red bit flour, formulation 3 with 15% red bit flour substitution, and formulation 4 with 18% red bit flour substitution. %. The results of the organoleptic assessment scores by panelists were analyzed using Excel 2010 and SPSS with descriptive tests. Based on the results of the analysis, it was found that cookies formulation 2 was the most preferred by panelists in terms of taste, color, smell, and texture. Based on the test of antioxidant activity of cookies formulation 2 30690 µg/mL, its means that it still potential as an antioxidant substance weak as classified. ABSTRAK Penelitian ini merupakan penelitian eksperimen yang bertujuan untuk membuat formulasi cookies tepung tempe yang disubstitusi dengan tepung bit merah. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan perlakuan penambahan tepung bit merah pada cookies tepung tempe dengan konsentrasi yang berbeda. Proses pembuatan cookies meliputi pencampuran tepung, pengocokan margarin, telur, gula halus dengan mixer, pencetakan, dan pemanggangan menggunakan oven. Uji organoleptik (kesukaan) melibatkan 30 panelis semi terlatih. Cookies tepung tempe dengan substitusi tepung bit merah dengan 4 formulasi yaitu formulasi 1 konsentrasi 0% (kontrol), formulasi 2 dengan 12% substitusi tepung bit merah, formulasi 3 dengan substitusi tepung bit merah 15%, dan formulasi 4 dengan susbtitusi tepung bit merah 18%. Hasil skor penilaian organoleptik oleh panelis dianalisis menggunakan Excel 2010 dan SPSS dengan uji deskriptif. Berdasarkan hasil analisis didapatkan cookies formulasi 2 adalah yang paling disukai oleh panelis dari segi rasa, warna, aroma, dan tekstur. Berdasarkan hasil uji aktivitas antioksidan cookies formulasi 2 yaitu 30690 µg/mL yang artinya masih berpotensi sebagai zat antioksidan namun tergolong sangat lemah.

Black garlic is a garlic that experiences warming at a certain temperature and time to find higher antioxidant activity. This research aimed to know effect of antioxidant content’s stability of extract BG to pH and temperature. The experimental design used in this research was a completely randomized design with replication, which consisted of two factors. The first factor was pH (4, 6 and 8). The second factor was temperature (30, 50 and 70ºC). Data were analyzed with analysis of variance, followed by Duncan test. The results showed that pH and processing temperature very influential to antioxidant activity, total phenolic and total flavonoid. The results showed that the best treatment was pH 4 and temperature 30ºC which the best resulted antioxidant activity, total phenolic and total flavonoid that stablest. The resulted of antioxidant activity, stability of total phenolic and total flavonoid that were 75,13%, 42,47% and 77,71%. The treatment of pH and processing temperature change compounds of extract black garlic. Myricetin and quercetin appeared on treatment pH 4 with temperature 30ºC and pH 8 with temperature 70 ºC. The treatment of pH and processing temperature of black garlic extract reduced antioxidant activity, total phenol and total flavonoid. pH and temperature form new compounds.

Jelly candy is a favorite snack of various ages from children to adults because it has an attractive color, delicious aroma and taste, and a chewy texture. In this study, papaya juice (Carica papaya L.) was used as a base ingredient for making jelly candy because papaya is a fruit that is very easy to find and has a relatively cheap price. In order to improve the quality of the papaya jelly candy, roselle calyx extract (Hibiscus sabdariffa L.) was also added. Roselle calyx has been known to have high antioxidants because they contain anthocyanin pigments. The purpose of this study was to determine the effect of variations in the addition of roselle calyx extract to the papaya jelly candy. The experimental design in this study was a completely randomized design with variations in the addition of roselle calyx extract by 0% (control), 15%, 30%, and 45%. The parameters tested in this study include chemical, physical, microbiological, and organoleptic qualities. The results of the research that have been carried out show the addition of 45% roselle calyx extract can produce the best papaya jelly candy based on water content, total titrated acid, antioxidant activity, total anthocyanin, texture, color, and microbiological tests which include total plate count and numbers of yeast molds.

Soursop leaf tea is a health drink that contains steroid compounds, terpenoids, flavonoids, kumari, tannins, and alkaloids. The flavonoids and tannins in soursop leaves act as antioxidants. Since it has an unpleasant aroma, cinnamon is added to add scent and flavor. This study aimed to determine the effect of cinnamon powder on the soursop leaf tea's antioxidant activity. This study employed the completely randomized design method (CRD) with two factors: the soursop leaves and cinnamon powder concentrations. This study consisted of four treatments, namely SP0 (100% soursop leaves), SP1 (90% soursop leaves and 10% cinnamon powder), SP2 (80% soursop leaves and 20% cinnamon powder), and SP3 (70% soursop leaves and 30% cinnamon powder) within three repetitions. The proximate test was focused on antioxidant activity analyzed by ANOVA at α = 5%. The organoleptic test covered the color, taste, aroma, and other overall preferences by qualitative descriptive tests. The results showed that the highest antioxidant (29.19%) could be found in the SP3 sample (70% soursop leaves and 30% cinnamon powder), while the preferred organoleptic test was the SP2 sample.
