Abstract

Sweet potato has the potential to be developed as a source of raw material for making flour to substitute the use of wheat flour. The sweet potatoes used in this study as flour were sweet potatoes with purple flesh. Processing of purple sweet potato into flour can be done through the drying process. The purpose of this study was to evaluate the effect of the temperature used in the cabinet dryer on the rate of degradation of the nutritional components and bioactive components of purple sweet potato during the flouring process. Purple sweet potato is cleaned and made into chips with a size of ± 2 mm and then dried in a cabinet dryer. The variables in this study were temperature (50 ºC, 55 ºC, 60 ºC) and drying time (1, 2, 3, 4, 5, 6, 7, 8 hours). Each treatment was repeated 3 times and observed for water content, total sugar, reducing sugar, beta-carotene, anthocyanins, polyphenols, and antioxidant activity. Data were analyzed using a Completely Randomized Factorial Design followed by Duncan's Test. The results showed that temperature and drying time had a significant effect on the nutritional and bioactive components of purple sweet potato during the drying process. A temperature of 60 ºC can be recommended as one of the temperatures used to dry purple sweet potatoes with a drying time of 5 hours. At this temperature and drying time, the anthocyanin content and antioxidant activity still have their biological properties. The characteristics of purple sweet potato slices in this treatment were 9.62% water content, 0.84% total sugar, 0.52% reducing sugar, 0.74% beta-carotene, 25.25% anthocyanins, 4.93% polyphenols, and 2.29% antioxidant activity.

Abstract

This research is an experimental study that aims to determine the effect of the concentration of red dragon fruit extract on the quality and antioxidant activity of probiotic soyghurt products or fermented soy milk. This study used an experimental method with a RAL experimental design consisting of 4 treatments and 3 replications. The treatment variable in this study was the addition of red dragon fruit extract with concentrations of K(0%), A(5%), B(10%), and C(`15%), while the observation variable in this study was the total calculation of LAB, protein content, fat content, vitamin C content, pH, total acid, antioxidant activity analysis, and organoleptic testing (color, aroma, texture, and taste). The data obtained from the results of this study were tested for normality and homogeneity using SPSS version 20 software. Then, the analysis was carried out using analysis of variance (ANOVA) and continued with Duncan's further test. Based on the results of normality and homogeneity tests, all data were normally distributed and homogeneous. Based on the analysis of variance ANOVA obtained Fcount>Ftable 5% level. This shows that all treatments have a significant effect on the observed variables in the study. The results showed that treatment C was the best treatment because it was preferred by the panelists with a total BAL value of 11.23 Log Cfu/ml, 6.1% protein content, 5.32% fat content, 0.09% vitamin C, pH 4.65. , total acid 1.74%, and antioxidant activity 62.95%.

Abstract

The aim of this research was to determine the effect of giving Bacillus subtilis concentrations on caffeine levels and the physicochemistry of Arabica coffee beans. This study used a Complete Randomized Design (RAL) where the concentration of B. subtilis was 0%, 1%, 2%, 3%, 4%, 5%. Variables observed in this study included total plate numbers (ALT), total titrated acid (TAT) and pH, as well as arabica coffee bean tests (water and caffeine content). The results of this study show that B. subtilis affects ALT, TAT, pH, water content and caffeine content of fermented liquid in arabica coffee beans. The lowest caffeine content of arabica coffee beans is made from arabica coffee beans added 5% B. subtilis during fermentation with a caffeine content of 1.34%.

Abstract

Tofu is a processed food product whose raw material uses soybeans. The purpose of the research conducted was to determine the effectiveness of the addition of natural coagulants in the form of lime and starfruit in the manufacture of tofu with substitution of koro pedang. The research method used is a quantitative method using a two-factor factorial design and three replications. The concentration of natural coagulants in this study were 5% and 7% lime and 20% and 40% starfruit wuluh. This study produced water content values ranging from 70.53-82.31%, cyanide acid levels ranged from 5.77-8.95 mg/kg, protein levels ranged from 9.53- 16.30% and hedonic divided into two, namely hedonic quality in raw tofu includes color ranging from 3.25-3.56%, texture ranging from 3.21-3.68% and aroma ranging from 3.19-3.67% while hedonic quality in fried tofu includes color ranging from 3.20-3.57%, texture ranging from 3.08 - 3.59%, aroma ranging from 3.39-3.73% and taste ranging from 3.43-3.77%. Furthermore, the resulting normality test shows that the data is normally distributed with the Shapiro-Wilk value obtained which is> 0.05 and the homogeneity test shows a significant value which is> 0.05.

The form of research used is research and development (R&D), which aims to develop or modify an existing product. The data analysis technique used in this research is quantitative data analysis technique. The research results concluded that the capacity and percentage level of success of the tool had a capacity of 7 kg in 11.5 minutes or 0.61 kg in 1 minute, with a percentage of peeled pepper seeds of 98.22 percent and pepper seeds not peeled of 1.78 percent.
