Abstract

Herbal tea is a functional drink made from a mixture of dried plants that are beneficial to the body. Corn silk has the potential to be used as herbal tea because it contains cholesterol-lowering β-sitosterol and phenol compounds as antioxidants. However, the taste is astringent and the aroma is weak, so it is necessary to add lemongrass which has a distinctive aroma and refreshing taste from essential oils. The aimed of this research was to obtain the selected ratio of corn hair and citronella to the quality characteristics of herbal tea according to SNI 3836: 2013 dry tea in packaging. This research was conducted experimentally using a completely randomized design with four treatments, namely the ratio of corn hair and citronella RS0 (100:0), RS1 (85:15), RS2 (70:30), and RS3 (55:45). The parameters observed in this research were moisture, ash, crude-fiber, polyphenol, and antioxidant activity. The antioxidant activity was measured using the DPPH method. The results showed that the RS2 treatment herbal tea with the ratio of corn hair and citronella (70:30) was the selected treatment which had a moisture of 6.25%, ash of 4.36%, crude fiber of 9.34%, polyphenol of 58.28 mg GAE/g or 5.82%, and antioxidant activity of 131.38 ppm.

Abstract

Crackers are snacks made from starch-containing ingredients. The raw material for making crackers is basically tapioca. Efforts to diversify sago crackers need to be made to increase protein content, one of which is by adding moringa flour. This study aimed to determine the effect of the ratio of sago starch and moringa flour on the physicochemical and organoleptic properties of sago crackers. The treatment in this study was the ratio of sago starch and moringa flour namely: SK1 (100:0), SK2 (95:5), SK3 (90:10), and SK4 (85:15). The data obtained were statistically analysed using analysis of variance and continued with duncan’s multiple range test (DMRT) at a 5% level. The results of variance analysis showed that the ratio of sago starch and moringa flour used significantly affected moisture, ash, protein, and fat contents, expandability, breakability, descriptive and hedonic sensory assessment, and overall assessment of crackers. The best treatment in this study was the SK2 (95:5) with characteristics of moisture content of 3.36%, ash content of 0.02%, protein content of 2.86%, fat content of 12.71%, expandability of 38.89%, breakability of 2.75 N/s with descriptive sensory assessment of greenish beige color, moringa leaf aroma, moringa leaf flavor, crispy, and overall rating was liked by the panellists.

Abstract

Oil palm trunks and coconut shells are biomass waste that can be used to make charcoal briquettes as an alternative energy source since they contain lignin and cellulose. The goal of this study was to find the optimum briquette character from a combination of oil palm trunk charcoal and coconut shell charcoal. This study employed a completely randomized design (CRD) with five treatments and three replications. In this investigation, the ratios of oil palm trunk to coconut shell charcoal were 90:10, 80:20, 70:30, 60:40, and 50:50. The data was statistically examined using analysis of variance (ANOVA) and Duncan’s New Multiple Range Test (DNMRT) at the 5% level. The study revealed that the ratio of oil palm trunk and coconut shell charcoal had an effect on specific gravity, moisture content, fixed carbon content, ash content, and calorific value. Briquettes (50:50) with a density of 0.77 g/cm3, a water content of 4.07%, a volatile content of 14.52%, an ash content of 6.25%, a carbon content of 75.14%, and a calorific value of 7,998.07 cal/g were the best treatment.

Abstract

Pineapple (Ananas comosus) is a nutrient-rich tropical plant often processed into various products. At the same time, its peel waste contains valuable compounds such as bromelain enzyme and ascorbic acid, which are beneficial for skin care. Based on observations by students from the KKN MBKM program at the Faculty of Agriculture UNRI, it was found that the society is very interested in programs that discuss the processing of organic waste using simple methods, in line with the potential for utilizing agricultural product waste in Ujung Batu Timur village. This activity involves utilizing pineapple peel waste as a natural additive in the production of liquid soap through a community service program in Ujung Batu Timur, Rokan Hulu, Riau Province. This community service initiative aims to raise awareness among the community about organic waste management and enhance skills in creating economically valuable products. The methods used include socialization and practical training on making liquid soap from pineapple peel extract. The community service activities are carried out in three stages: preparation, implementation, and evaluation held at the Ujung Batu Timur Village Office and involving 23 participants. Post-training survey results show that most participants felt satisfied and benefited from this activity, with a satisfaction level of 80.45%. This program is expected to contribute to the development of micro-enterprises and improve the welfare of the local community.

Abstract

This community service activity began with the implementation of a Focus Group Discussion (FGD) with partners, which served as an initial exploration to design service programs that were relevant to the needs of the community. Partners in this activity are the manager of the school business unit and the parents of students. The results of the FGD resulted in an agreement on the focus of activities with stages, namely: (1) Education to improve food quality and nutrition in the prevention of stunting from an early age, and (2) Processing of local fish products (snakehead fish) as a zero waste-based food diversification. Through this FGD, an overview of needs, challenges, and opportunities that can be the basis for the implementation of counseling programs is obtained. It is hoped that the results of this activity can increase partners' knowledge about the processing of local fish food products in an effort to prevent stunting.
