Abstract

The high dependence of Indonesian border communities in Batam and Pontianak on imported products is influenced by the perception that foreign products are of better quality, and supported by easy geographical access. This study aims to analyze the relationship between demographic factors and consumer preferences for instant chocolate powdered drinks, in the context of changing border policies directed at becoming the gateway to the national economy. The research was conducted with a quantitative approach through a survey of 200 respondents who were selected purposively with the distribution of quotas per region. The variables analyzed included demographic factors (gender, age, marital status, education level, and type of occupation) as well as product attributes (color, aroma, taste, and texture), using the chi-square test to look at the relationships between variables. The results of the study show a significant relationship between demographic characteristics and consumer preferences. Preference patterns also show differences between regions: consumers in Pontianak tend to choose local products for price and quality reasons, while in Batam, preferences are more influenced by brand information and product image. The organoleptic test revealed that in the blind test, consumers objectively judge the product based on sensory attributes, while in the unblind test, preferences are influenced by the brand as well as demographic factors such as education and employment. These findings confirm the complexity of factors affecting the competitiveness of local products in border areas, as well as the importance of marketing strategies based on demographic segmentation and sensory quality improvement to reduce dependence on imported products.

Abstract

Cellulose is widely used in industries such as paper, textiles, and pharmaceuticals. A method to obtain pure cellulose is nata de soya production using Acetobacter xylinum, which converts glucose into cellulose through fermentation. Tofu wastewater serves as a suitable medium due to its rich organic content. Besides cellulose production, this process also helps reduce environmental pollution. This study aims to determine the effect of fermentation duration on biomass, yield, and microscopic characteristics of bacterial cellulose nata de soya. Fermentation process was carried out with time variations of 6, 12, 18, 24 and 30 days with three replicates each. The nata de soya product then measured for wet weight, washed, and pressed to reduce the moisture content before dried at 50°C until get a constant weight. Cellulose characterization was carried out using a dino-Lite microscope and a Scanning Electron Microscope (SEM) instrument to observe the structure of bacterial cellulose fibres. The results showed that the duration of medium fermentation affected the thickness of nata de soya and the amount of cellulose yield. Based on the nata biomass, the best fermentation duration is 24 days, which demonstrate the highest average wet weight of 494 grams/L medium. However, for the dry weight and the percentage of yield, the best result was obtained at the fermentation duration on the 30th day, which was 26.23 grams/L medium; 5,28%, respectively. It is concluded as the longer fermentation duration, the more fibre tendrils and bacterial cellulose content the nata de soya is produced.

Abstract

Purple sweet potato and corn flours are considered promising composite alternatives to rice flour in traditional bakery products due to their higher nutritional value and potential to enhance product appearance. This study aimed to evaluate the effects of a purple sweet potato–corn flour composite on β-carotene content and color characteristics of apem cake, a traditional Indonesian steamed cake. A quantitative experimental design was employed using a Completely Randomized Design (CRD) comprising four treatment formulations with two replications. The analyzed variables included β-carotene concentration and instrumental color values (L*, a*, b*). Data were analyzed using one-way ANOVA followed by Duncan’s Multiple Range Test (DMRT) for post hoc comparisons. The results indicated that formulation B exhibited the highest lightness value (L* = 40.18; p = 0.020), demonstrating a significant improvement in brightness. The a* value (red-green axis) did not differ significantly across treatments (p = 0.090). In contrast, b* values (yellow-blue axis) decreased significantly (p = 0.002), with formulation D showing the lowest value, indicating a shift toward a bluish hue. Notably, formulation D also recorded the highest β-carotene content. The best formulation is D with the b* value of 14,3 and betacaroten at 91.71%.
Sintesis dan aplikasi nanoemulsi betalain kulit buah naga merah (Hylocereus polyrhizus) sebagai pewarna alami pada produk es krim: Synthesis and application of betalain nanoemulsion from red dragon fruit peel (Hylocereus polyrhizus) as natural colorant in ice cream products Utami, Cahyaning Rini; Ifadah, Qodhrul Izza Irdianis

Abstract

Betalains are promising natural colorants, yet their stability often poses challenges. This study employed Deep Eutectic Solvent (DES)–based extraction coupled with nanoemulsion formulation to enhance the stability and performance of betalains from red dragon fruit (Hylocereus polyrhizus) peel for application in ice cream. A completely randomized design with one factor and three replicates was used. Responses measured included betalain content, pH, droplet size, color coordinates (L*, a*, b*), antioxidant activity, and sensory attributes (aroma, color, texture, taste). Increasing extract concentration significantly affected most responses, generally intensifying redness and antioxidant capacity while maintaining desirable physicochemical characteristics. Based on the effectiveness index, formulation F5 (12 mL extract) showed the most favorable overall performance, delivering the highest antioxidant activity, superior physicochemical properties (stable nano-scale droplets, appropriate pH, vivid color), and the greatest sensory acceptance. These results demonstrate that DES-based betalain nanoemulsions are effective natural colorants for ice cream, with F5 recommended as the optimal formulation.

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.
