This study aims to determine the effect of the comparison of black tea and red ginger to the characteristics of teabags and know the comparison of black tea and red ginger to get the best characteristics of tea bags. The experimental design used was Completely Randomized Design with comparison treatment of black tea and red ginger which consist by 6 levels : 100%:0%, 90%:10%, 80%:20%, 70%:30%, 60%:40% and 50%:50%. The treatment was repeated 3 times to obtain 18 units of experiment.. The data obtained were analyzed by variance and if the treatment had significant effect followed by Duncan test. The result showed that tea bags with comaparions of 80% black tea powder and 20% red ginger powder is the best treatments with a water content of 7,78%, extract content of 27,13%, total phenol 247,10 mgGAE/g extract, flavonoids 401,72 mgQE/g extract, antioxidant activity 74,68%, color was liked, distinctive aroma of ginger and rather liked, distinctive taste of ginger and rather liked, overall acceptance was rather like. Keywords : black tea, red ginger, teabag

The purposes of this research were to know the effect of rice flour and pumpkin ratio on the characteristics of sumping and to find the right ratio from rice flour and pumpkin to produce sumping with the best characteristics. The completely randomized design was used in the research with treatment that is the ratio rice flour with pumpkin which consist of 25% : 75%; 30% : 70%; 35% : 65%; 40% : 60%; 45% : 55%; 50% : 50%. The treatment was repeated 3 times to obtained 18 units. The data obtained were analyzed of variance and if the treatment had an effect on the variable then continued with Duncan test. The results showed that rice flour and pumpkin ratio had significant effect to water content, ash content, total caroten, skoring test (colour, aroma, texture, taste) and hedonic test (colour, aroma, texture, taste, and overall acceptance). The ratio of rice flour 25 % and pumpkin 75% produces with the best characteristic namely water content 57,55%, ash content 1,74%, total caroten content 10868,52 ?g/g, color yellow and like, flavor pumkin typical and rather like, texture chewy and like, taste typical pumkin and like and overall acceptance like. Keywords : Rice flour, pumpkin, pumpkin sumping

PENGARUH PERBANDINGAN TEPUNG BERAS MERAH PREGELATINISASI DENGAN TERIGU TERHADAP KARAKTERISTIK CRACKERS I Gusti Ayu Atyantha Danawati; Anak Agung Gede Ngurah Anom Jambe; I Gusti Ayu Ekawati

The purpose of this research to find the effect of the comparison of pregelatinization red rice flour with wheat flour on the characteristics of crackers and also to find the best ratio of red rice flour with wheat flour to the characteristics of crackers. This study used a Compeletely Randomized Design (CRD) with a comparison of red rice flour pregelatinization with wheat flour consisting of 6 treatment namely 0% : 100%;10% : 90%; 20% : 80%; 30% : 70%;40% : 60%; 50% : 50%. The treatment repeated 3 times, so that resulting in 18 experimental units. The resulting data is analyzed with variance and if the inter treatment effect on the observed variance, then continue with Duncan test. The result showed that pregelatinization red rice flour and wheat flour significantly affected to water content, protein content, total phenol, and antioxidant activity in crackers and had no significant effect on ash content. The comparison ratio of 50% pregelatinazation red rice flour with 50% wheat flour produces crackers with the best characteristics, namely: water content of 1.15%, ash content of 1.73%, 10.30% protein content, total phenol 158.83% and 45.17% antioxidant activity colour very like, texture crispy, overall liked, aroma,taste and overall acceptance like. Keywords : crackers, red rice, pregelatinized, wheat flour

PENGARUH SUHU DAN WAKTU EKSTRAKSI DENGAN GELOMBANG ULTRASONIK TERHADAP AKTIVITAS ANTIOKSIDAN EKSTRAK DAUN JAMBU BIJI (Psidium guajava L.) Sandra Sekarsari; I Wayan Rai Widarta; Anak Agung Gede Ngurah Anom Jambe

This research was conducted to determine temperature and time extraction with ultrasonic waves on the antioxidant activity of guajava leaf extract and obtain the temperature and extraction time with ultrasonic waves that are appropriate to produce the highest antioxidant activity. The experimental design used in this research was a Factorial Completely Randomized Design with time treatment consisting of 3 levels, namely 10 minutes, 20 minutes and 30 minutes and temperatures consisting of 3 levels, namely 40°C, 45°C and 50°C. The treatment was repeated two times, so that 18 experimental units were obtained. Data were conducted using analyzed of variance and if treatment had a significant effect, followed by Duncan's test. The results showed that the interaction between temperature and time of extraction of guajava leaves with ultrasonic waves had a very significant effect (P<0.01) on yield, total phenol, total flavonoids, total tannins and antioxidant activity of guajava leaves. The treatment of extraction temperature and extraction time of guajava leaves with ultrasonic waves had very significant effect (P<0.01) on yield, total phenol, total flavonoids, total tannins and antioxidant activity of guajava leaves. The best results showed that temperature of 45oC with time 20 minutes result antioxidant activity based on 89.03 %, free radical inhibition percentage with IC50 values 3.55 mg/L, yield 16.26 %, total phenol was 331.77 mgGAE/g extract, total flavonoids was 637.33 mgQE/g extract and total tannins were 583.75 mgTAE/g. Keywords : antioxidant, guajava leaves, temperature, time, ultrasonics
