Abstract

This study aimed to obtain the best formulation in the manufacture of velva made from nipah fruit combined with rosella flower petals. This research was conducted experimentally using a completely randomized design (CRD) of four treatments and four replications. The treatments in this study were the ratio of nipa palm pulp (N) to rosella flower petal pulp (R), namely NR1 = 90:10 (w/w), NR2 = 80:20 (w/w), NR3 = 70:30 (w/w), and NR4 = 60:40 (w/w). The results were statistically analyzed using Analysis of Variance (ANOVA). The results showed that the ratio of nipa palm pulp: to rosella petal pulp significantly affected crude fiber content, acidity, and velva melting time. The results also showed that the treatment affected the velva sensory test parameters, including color, aroma, and taste. Meanwhile, the difference in the ratio of nipa palm pulp: to rosella petal pulp had no significant effect (P>0.05) on the softness of the velva. The hedonic sensory test showed that the ratio of nipah fruit and rosella had a significant effect (P<0.05) on overall velva acceptance. Based on chemical analysis and velva sensory test, the treatment selected in this study was the ratio of nipah fruit pulp to rosella flower pulp 70:30 (NR3) with a fiber content of 1.90%, overrun 30.32%, and acidity 4.70. The velva melting time was 9.10 m, and the sensory assessment had a red color (2.50), soft texture (3.80), slightly fragrant with nipah fruit (2.70), and slightly tasted like nipah fruit (2.60), and overall acceptance liked by panelists (4.40).

Abstract

Making fruit leather needs to be added hydrocolloids to improve plasticity that often occurs, especially in raw materials that contain low pectin, such as mango and rosella. One solution that can be done is to add ingredients that have good plasticizing properties, such as carrageenan. The study aimed to obtain the best concentration of carrageenan in the manufacture of fruit leather. This research was conducted experimentally using a completely randomized design (CRD) consisting of five treatments as follows: without the addition of carregeenan (K0); the addition of carrageenans for 0.3% (K1), 0.6% (K2), 0.9% (K3), and 1.2% (K4). The data obtained were analyzed statistically using analysis of variance (ANOVA), then analyzed with duncan’s multiple range test (DMRT) at 5% level. The results showed that addition of various concentrations of carrageenan significantly affected the moisture, ash, fiber content, total sugar, pH value, descriptive color, and descriptive and hedonic texture of the mango-rosella fruit leather but did not significantly influence the hedonic color, aroma, taste, overall assessment, and descriptive aroma and taste. The best treatment in this study was K1 (addition of 0.3% carrageenan) with moisture content 13.88%, ash 0.37%, fiber 5.16%, total sugar 49.72%, pH value 2.97. The K1 treatment had slightly red color description, has a mango and rosella aroma, a sweet, slightly sour taste, and slighlty chewy texture. The average panelist liked the K1 treatment in terms of color, aroma, taste, texture, and overall value.

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

The primary objective of this study was to evaluate the effect of varying ratios of pandan leaves (Pandanus amaryllifolius) and stevia leaves (Stevia rebaudiana) on the chemical and sensory characteristics of herbal tea, identifying the optimal formulation relative to SNI 3945:2016 standards. Unlike traditional tea derived from Camellia sinensis, herbal infusions utilize diverse plant materials valued for their therapeutic properties. Pandan leaves, in particular, contain essential bioactive compounds—including polyphenols, alkaloids, saponins, tannins, and flavonoids—that provide significant antimicrobial and antioxidant  benefits. The experiment was conducted using a completely randomized design with four treatments and  four replications. The treatments consisted of different ratios of pandan to stevia leaves: 60:40 (PS1), 65:35  (PS2), 70:30 (PS3), and 75:25 (PS4). The observed parameters included moisture content, ash content,  antioxidant activity, total polyphenols, and sensory evaluation (color, aroma, taste, and overall acceptance).  Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s multiple range test  (DMRT) at a 5% significance level. The results showed that the ratio of pandan and stevia leaves  significantly affected moisture content, ash content, antioxidant activity, total polyphenols, and sensory  attributes. The best treatment was PS1 (60:40), which exhibited 6.35% moisture content, 7.08% ash  content, antioxidant activity of 21.75 ppm, and total polyphenols of 84.34 mg GAE/g. Sensory evaluation  indicated that the product had a characteristic pandan aroma, slightly bitter taste, and slightly greenish  color, with acceptable overall preference by panelists.
