Abstract

Compound of 3,3'-(4-(2-amino-4,5-dimethoxyphenyl)pyridine-2,6-diyl)dianiline (CHP) has been synthesized via three-step synthetic procedure from veratraldehyde as starting material and 4-(4,5-dimethoxy-2-nitrophenyl)-2,6-bis(3-nitrophenyl)pyridine (CHP-1) as an intermediate compound. The CHP-1 was reduced using hydrazine hydrate catalyzed by 10% Pd/C to the final target of CHP. The spectroscopic study revealed that CHP in acetonitrile could detect formaldehyde through fluorescence enhancement and showed color change from yellow to blue under the 365 nm portable ultraviolet lamp as a response. Based on the fluorescence spectra, the emission wavelength of CHP in acetonitrile was shifted from 526 to 480 nm after addition of formaldehyde. Limit detection (LOD), selectivity, sensitivity, and computational study geometry of CHP as a chemosensor for formaldehyde has also been investigated. CHP could also be applied as a test paper for the detection of formaldehyde qualitatively.

Abstract

Formaldehyde in solution, commonly known as formalin, is often utilized. In Indonesia, there is widespread misuse of formalin as a food preservative. Formaldehyde has been identified as a carcinogenic substance by the International Agency for Research on Cancer (IARC) and the Environmental Protection Agency (EPA). Based on this background, the present study developed a sensor compound capable of detecting formaldehyde obviously. The compound 3'-(4-(3,4-dimethoxyphenyl)pyridine-2,6-diyl)dianiline (ChP-2A) has been successfully synthesized through the reduction reaction of the compound 4-(3,4-dimethoxyphenyl)-2,6-bis(3-nitrophenyl)pyridine (ChP-0A) using 80% hydrazine hydrate and 10% Pd/C as a catalyst. The ChP-2A compound in acetonitrile exhibits a significant decrease in fluorescence intensity (turn-off) after the addition of formaldehyde, and it has been successfully applied in the form of a test paper for the detection of formaldehyde qualitatively

Abstract

Innovative use of waste into herbal beverage products the waste treatment process starts from the stage of roasting cocoa beans, breaking the beans and peeling the skin, sorting, drying, preparation of packaging and materials, filling and mixing, giving silica gel and labelling the expiration date. The raw materials needed are cocoa bean husk, dried cardamom, and cinnamon powder. While the packaging material uses PET plastic bottle packaging. Before the product is marketed, it is necessary to conduct a feasibility analysis of the selling price. The analysis shows that the selling price of chocolate product of Rp. 15,000 is feasible because profit taking is 48% with the selling price per unit more than the cost per unit. The net profit margin of chocolate product of 32.6% means that the company is considered efficient in determining the selling price of its products and successfully controlling costs in it because the NPM figure is > 5%. Hedonic tests were also conducted to determine consumer acceptance of the product through a hedonic test of 20 panelists based on the parameters of color, aroma, taste, and packaging. The hedonic test scale 1 shows that consumers do not like it very much, a scale 2 does not like it, a scale 3 likes it, and a scale 4 likes it very much. The average level of preference for color parameters is 3.58, aroma is 3.31, taste is 3.47, and packaging is 3.84 which indicates that the panelists like these 4 parameters.

Abstract

Lactose-intolerant people are unable to ingest cheese since it includes lactose. Lactose-free cheese can be made using coconut milk as an alternative. Coconut milk can substitute milk as a raw material for cheese production because it is rich in proteins such as albumin, globulin, prolamin, and glutelin. This research aims to determine how different proportions of coconut milk and soy extract affect the nutritional value of coconut milk cheese. Cheeses with 80:20, 70:30, and 60:40 ratios of coconut milk to soy extract are made by directly acidifying soy extract with lemon juice. Protein, lipid, and moisture content were all evaluated. At compositions 80:20, 70:30, and 60:40, the protein content of coconut milk cheese was 3.85%; 4.80%; and 5.73%, respectively. Coconut milk cheese had lipid contents of 28%, 27%, and 25.74%, respectively; the moisture contents were 64.93%; 61.92%; and 60.49%. This research contributes to utilizing coconut milk as a milk substitute.

Abstract

The empowerment of the community in Tunggularum, Wonokerto, aims to optimize lemongrass (Cymbopogon citratus) cultivation into essential oil products through community-based training and practical skills development. Lemongrass is widely cultivated in the area but is underutilized due to limited knowledge of its potential economic value, particularly in essential oil production. This community service project focused on addressing this gap through two primary activities: a socialization session on the essential oil distillation process and hands-on training in the operation of distillation equipment. The project involved 20–25 local participants, predominantly women, who attended both the theoretical and practical sessions. The results showed significant improvements in the participants' knowledge and skills. Over 70% of participants reported feeling more capable of managing the local lemongrass resources and demonstrated an enhanced understanding of the distillation process. The training also fostered new skills in operating distillation equipment, which further encouraged the participants to explore the business potential of lemongrass essential oil production.

Abstract

Herbal tea imparts health benefits largely due to its polyphenol-based antioxidant activity. Soursop leaves contain compounds including flavonoids, tannins, alkaloids, acetogenins, and saponins. Red galangal contains compounds such as saponins, tannins, flavonoids, and essential oils. The addition of red galangal to soursop leaf tea not only enhances the antioxidant activity of the tea but also improves its flavor. This study investigated the influence of adding red galangal simplicia to soursop leaf tea on its chemical and organoleptic properties, and also its antioxidant activity. The research method was based on varying ratios of the two ingredients (soursop leaves: red galangal simplicia), specifically F1 (100%: 0%), F2 (85%: 15%), F3 (80%: 20%), F4 (75%: 25%), F5 (70%: 30%), with three repetitions. The chemical properties tested included water content, ash content, antioxidant activity, flavonoid content, polyphenol content, and tannin content. The organoleptic tests included assessments of color, aroma, taste, aftertaste, and overall preference. The results demonstrated that soursop leaf tea with the addition of red galangal simplicia had a significant effect on its chemical properties, organoleptic properties, and antioxidant activity. The analysis results showed the lowest water content at 8.51% (F5), the lowest ash content at 7.03% (F5), the highest antioxidant activity at 33.37 ppm (F5), the highest flavonoid content at 95.46 mgQE/g (F5), the highest total phenolic content at 46.10 mgGAE/g (F5), and the highest tannin content at 42.63 mgCE/g (F5). Organoleptic assessment based on color preference scored 3.83 (F1), with the highest aroma score at 3.70 (F5), the highest taste score at 3.51 (F5), the highest aftertaste score at 3.30 (F5), and the highest overall preference score at 3.58 (F5). Based on these results, it can be concluded that the most preferred treatment, with the highest phytochemical contents and antioxidant activity, was treatment F5 with a concentration of 70% soursop leaves and 30% red galangal simplicia.
