Abstract

Lime is a natural ingredient that contains bioactive compounds such as antioxidants (vitamin C, palmitate, polyphenols), essential oils, and high antibacterial properties. The bioactive compounds are obtained by extraction using the maceration method. This study aims to determine the effect of the type of solvent and the time of maceration on the characteristics and stability of the extract of lime (Citrus amblycarpa) as a natural antioxidant in food, and to determine the type of solvent and the most effective maceration time. Extraction of lime using 3 types of solvents (ethanol, methanol, and acetone) and 3 periods of maceration, namely (2 hours, 4 hours, and 6 hours). The variables observed in the first stage were: yield, vitamin C, total phenol, antioxidant capacity), effectiveness index test. The second stage of research was carried out by storing lime extract in a temperature variation treatment consisting of 6 levels (S1 = 0oC, S2 = 20oC S3 = 40oC, S4 = 60oC, S5 = 80oC and S6 = 100oC) then observed the trend rate of vitamin C content. The effectiveness index test showed that the methanol solvent treatment and 6 hours maceration time were able to produce the best lime extract characteristics with yields of 35.08%, vitamin C of 7,580.90 mg AAE / 100g, total phenol of 6,484.54 mg GAE / 100g , and the antioxidant capacity of 4,928.79 mg GAEAC / 100g. The higher the storage temperature, the lower the vitamin C content of the lime extract. Changes in vitamin C content to the effect of temperature are shown by regression y = -11.433x + 7518.6, with a correlation coefficient (r) -0.9251. The highest vitamin C content at 0oC was 7338.47 mg AAE / 100g and the lowest at 100oC was 6163.59 mg AAE / 100g. The results of the study concluded that the type of solvent treatment and maceration time affected the characteristics of the lime extract.

Abstract

Pokak plant, also known as takokak or prickly nightshade (Solanum torvum Sw.), belongs to the Solanaceae family. The part of the plant commonly utilized was its leaves. Takokak leaves contained numerous bioactive components that can be developed into one of the functional foods, such as herbal tea. One crucial aspect in the herbal tea-making process is the drying temperature. The aimed of this research was to investigate the effect of drying temperature variations on the characteristics of takokak leaves herbal tea and to determined the optimal temperature that can yield the best characteristics of takokak leaf herbal tea. Parameters observed in this study included total phenols, total flavonoids, total tannins, vitamin C, antioxidant activity, and sensory properties comprising hedonic tests on color, taste, aroma, and overall acceptances. Data obtained were analyzed using analysis of variance (ANOVA), and if there was a significant effect of treatment on the results (P<0.05), it would be followed by the Tukey test. The results showed that variations in drying temperature significantly affected the values of total phenols, tannins, flavonoids, vitamin C, antioxidant activity, and sensory properties regarding color, aroma, taste, and overall acceptances of takokak leaf herbal tea. The best treatment was obtained at a drying temperature of 40°C with total phenol content of 31.58 mg GAE/g, total tannin content of 0.79 mg TAE/g, total flavonoid content of 14.23 mg QE/g, total vitamin C content of 7.92 mg AAE/g, antioxidant activity of 84.26%, and sensory properties for color, aroma, taste, and overall acceptances respectively were 5.73 (like), 5.27 (slightly like), 3.77 (neutral), and 3.91 (neutral).

Abstract

The teter plant is an herbal plant cultivated in Taro Village, rich in bioactive components with various health benefits, especially in its leaves. Taro villagers process teter leaves into a product called ‘loloh’ don teter. However, this product has the disadvantage of a short shelf life and is less desirable to the general public. As a solution, teter leaves can be processed into herbal tea. One important aspect in making herbal tea is the drying time. This study aimed to determine the effect of drying time on the Teter Leaf Herbal Tea characteristics and to obtained the appropriate drying time in making Teter Leaf Herbal Tea and its potential as a functional beverage. A Completely Randomized Design (CRD) was used with the treatment of drying time at 4 levels (12; 18; 24; and 30 hours at 50oC). The results showed that the drying time had a significant effect on the characteristics of Teter Leaf Herbal Tea. A drying time of 24 hours was the right time to produced herbal tea with a yield of 20.74%, moisture content of 7.21%, total phenols 40.71 mg GAE/g, total flavonoids 28.76 mg QE/g, total tannins 0.80 mg TAE/g, vitamin C 8.13 mg AAE/g, and antioxidant activity of 85.55%. Teter leaf has the potential to be developed into functional beverage.

Abstract

Sago, one of Indonesia’s staple foods, holds significant potential for food diversification due to its high carbohydrate content. However, despite its nutritional benefits, sago consumption remains less popular than corn and potatoes. Sago porridge, a traditional food product, can be developed into a healthy alternative, but its translucent brown color is visually unappealing, affecting consumer acceptance. This study aims to evaluate the optimal concentration of red dragon fruit extract as a natural colorant to enhance the visual appeal of sago porridge. The research method involved testing varying concentrations of red dragon fruit extract (0%, 2%, 4%, 6%) through sensory evaluation and physical analysis. Results showed that a 6% concentration yielded the highest acceptability, with the following physical properties: strawberry red color (L*:48.4; a*:70.8; b*:21.5), viscosity of 56,000 mPažs, texture force of 8.7980 N, and pH of 7.21. This study contributes through the innovative use of red dragon fruit extract as a natural colorant, improving both the visual appeal and nutritional value of sago porridge. The optimal 6% concentration provides a practical reference for local food industries to produce value-added products, supporting food diversification based on local resources and aligning with global trends in healthy, natural foods.

Abstract

This community service program with the Sari Mina Segara Group in Sangsit Village aimed to improve the competitiveness of Sudang Lepet and other fish-based products facing issues of short shelf life, simple packaging, and also limited marketing. The program introduced vacuum packaging, standardized labeling, and digital marketing strategies. Implementation involved training, mentoring, and equipment assistance. The results showed vacuum packaging extended shelf life, enhanced product safety, and reduced contamination risks. Informative labeling combined with Balinese cultural elements strengthened brand identity and consumer appeal. Digital marketing aspect has expanded product reach beyond local markets, improving sales, and visibility. Initial resistance to make a new technology was overcome through step-by-step guidance, leading to full participation and independent management of packaging and promotion. Overall, the program helps to strengthened product quality, broadened market access, and supported business sustainability in line with SDGs 8 and 12. Replication for other fisheries-based MSMEs is recommended to enhance competitiveness and eco-friendly packaging innovation.

Abstract

Used cooking oil, commonly produced from household cooking activities, poses serious risks to health and the environment if used repeatedly or disposed of carelessly. Repeated heating causes the formation of harmful compounds such as free fatty acids, aldehydes, and acrolein, while disposal into waterways can cause significant pollution. This community service program aims to enhance the knowledge and skills of housewives in Banjar Adat Taman Sari, Mengwitani Village, in processing used cooking oil into useful products, particularly solid soap. The activity conducted on July 24, 2025, employs a participatory learning-by-doing approach through interactive presentations and hands-on practice. Participants were introduced to the hazards of used cooking oil, purification techniques using activated carbon, and soap-making methods. Out of 37 participants, 4–6 was directly involved in the practical session, while the others followed via a live stream. The soap produced met the standards for cold-process soap in terms of color, scent, and texture. The program successfully raised environmental awareness, empowered women with practical skills, and opened up opportunities for household-scale businesses based on environmentally friendly practices.
