Abstract

Isotonic drinks are carbonated or non-carbonated soft drinks that contain sugar, nitric acid, and minerals to improve fitness. Isotonic drinks can be made from young coconut water by adding fruit juice to complement the nutritional content of isotonic drinks. One of the fruits that can be added is kelubi fruit. Kelubi is a fruit of the Araceae family that has complete nutritional content and is rich in organic acids. The purpose of this study was to determine the selected treatment of isotonic drink from coconut water added with kelubi fruit juice with different concentrations. The research was conducted experimentally using a complete randomized design with four treatments and four replications. The treatments in this study were K1 (3%), K2 (8%), K3 (13%), and K4 (18%). Data were analyzed statistically using analysis of variance, and differences between treatments were analyzed using Duncan’s New Multiple Range Test (DNMRT) at the 5% level. The result showed that the concentration of kelubi fruit juice significantly affected sodium content, potassium content, acidity, total acid, total sugar, and sensory assessment of isotonic drinks. The best treatment in this study was K2 (8%) with a sodium content of 412.40 mg/kg, potassium content of 315.40 mg/kg, pH 3.90, total acid 0.58%, total sugar 12.29%, and descriptive sensory assessment of orange color, kelubi scent, and sweet taste and hedonic assessment including color, aroma, and taste, and overall was preferred by the panelists.

Abstract

The COVID-19 pandemic, which initially began in Wuhan, China, quickly spread to more than 206 countries, including Indonesia. The use of vaccines is a preventive measure that is quite effective in preventing transmission of COVID-19. COVID-19 is caused by SARS CoV-2 which is the result of mutations from SARS-CoV which have higher virulence properties and spread faster. As of April 7, 2020, the number of infected people has reached more than 1,350,045 people including 76,328 people have died. Although there is no specific drug to treat COVID-19, administration of drugs such as remdesivir, fapilavir and chloroquin phosphate could cure 293,665 patients. In addition to therapeutic measures, preventive measures such as increased immunity are important steps to prevent transmission of various types of diseases. The results showed that probiotics could increase immunity through crosstalk between probiotics and intestinal mucosa. Interaction between probiotics and intestinal mucosa could increase the formation of lymphocytes (B and T cells), interleukin mainly IL-10 and IL-1β, immunoglobulins especially IgA, NK and Th-17 cells. The formation of this component will directly increase the body’s immune system against transmission of various diseases including COVID-19

Abstract

Frozen combination of fruit puree, sugar, and stabilizers is commonly used to produce velva, a frozen food product with a smooth texture similar to ice cream. Papaya fruit has a distinctive aroma, so if it is processed into processed velva products it will produce an aroma that is less favorable. The aroma of velva papaya can be improved by combining other fruits such as ambon banana which has a distinctive aroma. This research aimed to obtain the best ratio of papaya puree and ambon banana puree based on the quality characteristics of velva. This research used a completely randomized design (CRD) to produce 15 experimental units, with five treatments and three replications. The treatment in this study was PP1 (70:30), PP2 (60:40), PP3 (50:50), PP4 (40:60), and PP5 (30:70). Parameters observed include total solids, overrun, melting time, crude fiber content, vitamin C, and sensory evaluation. The variance results showed that overrun, melting time, crude fiber content, total solids, and sensory evaluation were significantly influenced by variations in the amount of papaya puree and ambon banana puree.

Abstract

Pagaruyung Village, Kampar, Riau, has great potential in the agricultural sector, particularly in the abundant production of pineapples. However, these agricultural products have not been fully utilized to improve the welfare of the community. One effort to optimize this potential is by developing Micro, Small, and Medium Enterprises (MSMEs) based on pineapple processing. The objective of this community service activity is to improve the capacity of MSME actors in business management to support the welfare of the community in Pagaruyung Village, Kampar, Riau. The activity involved 16 MSME members and village officials through pre-tests, material delivery, practice, interactive discussions, and post-tests. The results of the activity showed an increase in participants' knowledge and skills in business management, financial recording, product innovation, packaging techniques, and digital marketing strategies. A comparison of the pre-test and post-test results showed an increase in the average score of the participants, which was an indicator of the success of the training. In addition, a community of MSME actors in Pagaruyung Village was formed as a forum for collaboration and sustainable business development with the support of village officials. This activity had a positive impact not only on improving individual capacity but also on strengthening village MSME institutions, which is expected to contribute to improving the community's welfare in a sustainable manner.

Abstract

Yogurt is a beverage product processed through milk fermentation using Lactobacillus bulgaricus and Streptoccocus thermophilus. To add flavor, color, and aroma so as to improve the oraganoleptic properties of yogurt, it is necessary to add fruit in the manufacturing process such as dragon fruit. The use of red dragon fruit puree in yogurt is expected to increase the shelf life of yogurt, improve organoleptic, and increase the nutritional value of yogurt, as well the antioxidants content that function to prevent or delay several types of cell damage due to the oxidation. This study aimed to determine the quality characteristics of red dragon fruit yogurt during storage. The research was carried out using a completely randomized design with four treatments. The treatments in the study included storage times of 0, 7, 14, and 21 days at cold temperatures (4°C) which were repeated four times to obtain 16 experimental units. The data obtained were analyzed statistically using the ANOVA test. If the calculated F value is greater than or equal to the F table, then it is continued with Duncan's New Multiple Range Test (DNMRT) at the 5% level. The results of the analysis of variance showed that the storage times of red dragon fruit yogurt had a significant  effect on the degree of  the total lastic acid bacteria, total titratable acid, pH and viscosity. The results showed that the strorage period of red dragon fruit yoghurt had no significant effect on antioxidant activity as well as descriptive sensory assessment. The selected treatment was, P3 (14 days) red dragon fruit yogurt with, total LAB of 8.91 log CFU/ml, pH of 4.76, total titrated acid of 0.369%, viscosity of 726.82cP, and antioxidant of 10.52 ppm. The yogurt in P3 (14 days) treatment tasted sour, was red, smelled like dragon fruit, was a little thick.

Abstract

This study aimed to determine the optimal ratio of heat moisture treatment (HMT)–modified purple sweet potato flour and mung bean flour for flakes production. Flakes are instant foods typically made from cereal-based ingredients through baking. Purple sweet potato flour is a promising local raw material but has limited physical properties, which can be improved through HMT modification. Mung bean flour was added to enhance protein content. A completely randomized design with four treatments and four replications was applied. The treatments were ratios of HMT-modified purple sweet potato flour to mung bean flour: UK1 (80:20), UK2 (70:30), UK3 (60:40), and UK4 (50:50). Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Results showed that the flour ratio significantly affected moisture, ash, protein, fat, and carbohydrate contents, as well as crispness retention and sensory attributes (color, aroma, taste, and texture). The best formulation was UK4 (50:50), with moisture content of 3.18%, ash 2.11%, protein 13.81%, fat 2.82%, carbohydrate 78.08%, and crispness retention of 8.33 minutes. Sensory evaluation indicated a brownish-purple color, slight mung bean aroma, characteristic mung bean taste, and crispy texture, with overall acceptance rated as “liked.”
