Abstract

High coffee production is followed by a significant amount of coffee husk waste. However, the processing of coffee husk waste has not been fully optimized due to the lack of information regarding the unique characteristics of cascara from West Nusa Tenggara (NTB), Indonesia. The volatile components present in cascara can be measured and used as sensory threshold indicators. Therefore, this study aimed to identify the volatile and sensory components and determine the distinctive aroma and taste characteristics of cascara from arabica and robusta coffee. The research used a completely randomized design with GC-MS analysis and rate all that apply (RATA) sensory evaluation. The results showed that arabica var. Rinjani cascara contains the most dominant compounds, including caffeine (22.37% retention area) and 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (13.32% retention area). Robusta var. Rinjani cascara is dominated by caffeine (14.71% retention area) and quinic acid (13.92% retention area). Arabica var. Tambora cascara contains caffeine (40.82% retention area) and quinic acid (11.67% retention area), while robusta var. Tambora cascara has quinic acid (29.74% retention area) and mome inostol (22.98% retention area) as the most dominant compounds. Based on sensory profiles, arabica var. Rinjani cascara has a fruity, earthly, and green aroma with sour, sweet, and bitter flavors. Arabica var. Tambora cascara has a similar aroma with a sour, sweet, and bitter taste. Robusta var. Rinjani cascara features a floral, fruity, earthly, and green aroma with a similar taste. Meanwhile, robusta var. Tambora cascara has an earthly and green aroma with a bitter, sour taste. The RATA taste intensity test showed that robusta var. Rinjani cascara was sweeter than robusta var. Tambora. The sweet taste of cascara enhances its hedonic value, making it more preferred by panelists. This study provides the valuable sensory profile insights of cascara from NTB and references for developing value-added food products.Keywords: cascara, GC-MS, hedonic, RATA

Abstract

The suboptimal management of coffee waste affected a significant challenge because the coffee waste is often discarded without being utilized optimally. As a long-term impact, this can cause environmental pollution and loss of economic opportunities from coffee waste. A similar case occurred in the Cikamiri Sub Watershed, Garut, West Java. So it needed to be carried out by applying coffee waste to potential products such as cascara tea, liquid organic fertilizer, and bio-briquettes, but the product priority is not yet known. So that, this study aims to determine the priority for processing coffee waste into high-value products, such as cascara tea, liquid organic fertilizer (POC), and bio-briquettes using the Analytic Hierarchy Process (AHP) method in the Sub DAS Cikamiri, Garut, West Java. AHP was chosen for its ability to handle multi-criteria decision-making in a structured manner. The criteria used in this study include labor availability, investment cost, high market value, and material availability. The result showed that cascara tea (prevalence value of 68.6%) was the highest-priority product, followed by liquid organic fertilizer (prevalence value of 20.7%) and bio-briquettes (prevalence value of 10.6%). This study indicated that cascara tea had high market potential, while liquid organic fertilizer and bio-briquettes can be developed by considering environmental impact and sustainability. This research provides strategic recommendations to optimize coffee waste utilization, focusing primarily on cascara tea production to enhance economic value and positive environmental impacts. Keywords: analytical hierarchy process, bio-briquettes, cascara, coffee waste, liquid organic fertilizer

Abstract

Pluchea (Pluchea indica Less) leaf powder about 2 grams that was brewed in hot water at 95oC for 5 minutes resulted in herbal infusion with the highest panelist acceptance but low antioxidant activity compared to the other proportions in previous research. So that, it is necessary to add other herbs to increase antioxidant activity, i.e. moringa (Moringa oleifera Lam). This research aimed to determine the effect of moringa (Moringa oleifera Lam) leaves powder proportion to physicochemical, antioxidant, and sensory properties on pluchea (Pluchea indica Less) leaf powder infusion. The design of the research was a randomized block design (RBD) with a single factor, i.e. the proportions of pluchea and moringa leaves powder consisting of 7 treatment levels [100:0, 90:10, 80:20, 70:30, 60:40, 50:50, and 40:60 (%w/w) respectively]. The result showed that the proportion of moringa leaves powder significantly influenced the physicochemical and sensory properties of infusion. The higher proportion of pluchea leaf powder caused the increasing of moisture content, pH, lightness (L*), redness (a*), yellowness (b*), hue (oh), and chroma (C), but the decreasing of total acid and turbidity of pluchea leaf powder infusion. The improvement of pluchea leaf powder proportion significantly reacted on the bioactive compounds and antioxidant activities. The highest of the bioactive compounds and antioxidant activities were had of pluchea leaves powder infusion at 100:0 (%w/w) proportion of moringa leaves. Based on sensory analysis, the best treatment of pluchea leaf powder infusion was obtained at pluchea and moringa leaves proportion at 90:10 (%w/w) with 1.04 score. In the future, this formulation can be used as an alternative of herbal drink.  Keywords: infusion, leaf powder, physicochemical, pluchea indica less, sensory

Abstract

Free radical compounds in the body are very reactive to cells, so they can cause various diseases, one of which is diabetes mellitus. Compounds that are able to ward off free radicals are called antioxidants. Black garlic are known to contain bioactive compounds including SAC (S-allyl cysteine), polyphenols, and flavonoids which can treat diabetes or hyperglycemia. This research on black garlic as a hypoglycemic aims to determine the potential of black garlic from various types of garlic and types of black garlic which have the most potential as hypeglycemic in hyperglycemic rats. In vivo testing was carried out by inserting groups of rats in each cage (20–25°C) after being fed and drinking ad libitum. Each group of hyperglycemic rats was treated with black garlic from honan garlic, green spices, and lanang garlic at a dose of 250 mg / 200 g BW per day. Examination of tested animals includes body weight, hypoglycemic effect testing, blood glucose response testing, and malondialdehyde (MDA) levels. The results showed that black garlic can reduce blood sugar levels by 54.7%, blood glucose response by 1.25%, and reduce MDA levels by 72.98%. Honan black garlic can reduce blood sugar levels by 52.6%, blood glucose response by 12.29%, and reduce MDA levels by 68.87%, while green spiced black garlic can reduce blood sugar levels by 43.33%, blood glucose response was 37.67%, and decreased MDA levels by 59.76%. The type of black garlic that has a higher potential to reduce blood glucose levels in hyperglycemic rats is lanang black garlic.
