Abstract

Waste from patin fish (Pangasius pangasius) consumption is skin and fish bone. Its waste generally used as a raw material for food and industrial products because of fat, gelatin, collagen, and calcium compounds. Based on its calcium compound, another food application is the fortification of patin fish bone on wet spring roll wrapper. It is important to increase the consumption rate of calcium nutrition. Therefore, this research aimed to improve the proximate composition (especially calcium) of wet spring roll wrapper with 6% catfish bone flour fortification. The method used in this research was experimental with two treatments, i.e. the addition of 6% patin fish bone flour (A1) and 0% patin fish bone flour (A0) as a control. The parameters observed were moisture, ash, fat, protein, carbohydrate, and calcium content. The test procedure for each parameter observed is based on SNI 01-2354:2006. Sample testing was carried out in duplicate. The proximate composition of wet spring roll wrapper fortified with 6% patin fish bone flour consists of moisture, ash, fat, protein, carbohydrate, and calcium content respectively 60.21%, 2.61%, 0,71%, 3.96%, 32.51%, and 19.90 mg/100 g. Wet spring roll wrapper that was fortified with 6% patin fish bone flour (A1) had higher calcium content (19.90 mg/100 g) compared to wet spring roll wrapper with no fortification (control/A0) of the patin fish bone flour (8.22 mg/100 g). The moisture content of this calcium-rich wet spring roll wrapper is included in the Indonesian National Quality Standard (SNI) number 2987-2015 for wet noodles. This wet spring roll wrapper is one of diversified product using fishbone fortification to increase its calcium content. Keywords: fish bone, calsium, consumption, protein, waste

Abstract

Jember Regency has great potential in the agricultural sector, with cassava being one of its key commodities. Cassava can be developed into MOCAF (Modified Cassava Flour), produced through a fermentation process that modifies cassava cells using lactic acid bacteria. The development of the MOCAF agroindustry in Jember Regency has promising prospects due to the abundant availability of raw materials and increasing market demand. However, supply chain management optimization is necessary to ensure the effectiveness and efficiency of MOCAF agroindustry development. This study aims to generate effective and efficient strategy recommendations for developing the MOCAF agroindustry. The study uses the Interpretative Structural Modeling (ISM) method to determine the most dominant supply chain actors and the Analytical Hierarchy Process (AHP) method to determine the priority strategies for MOCAF agroindustry development. Based on the identification results, the MOCAF supply chain structure consists of four members: cassava farmers, collectors, MOCAF producers, and consumers. Farmers and cassava collectors act as suppliers of raw materials to producers, who then process them into MOCAF and sell them to consumers. The main actor in the supply chain is the consumer the party who determines the sustainability of the MOCAF agro-industry. Meanwhile, the most appropriate and prioritized supply chain development strategy is partnering with farmers to strengthen institutions within the supply chain. This strategy aims to improve the effectiveness and efficiency of relationships among supply chain actors, especially between the MOCAF agroindustry, farmers, and cassava collectors. This partnership is expected to ensure product quality, increase efficiency, stabilize, and even reduce the price of raw materials, which can increase the demand for MOCAF. Other strategies resulting from the AHP analysis are complementary to encourage the increase in MOCAF demand. Keywords: agroindustry, cassava, Jember Regency, MOCAF, supply chain

Abstract

The demand for xylose as a xylitol raw material is increasing. The resource for this material can be explored from agricultural waste such as lignocellulosic material which is widely available in nature, cheap, and renewable. The bioconversion of lignocellulose waste into xylose can use microbes, either single culture or microbial consortia. The purpose of this research is to find out the ability of Bacillus subtilis, Aureobasidium pullulans, and Penicillium janczewskii to convert xylan of cassava waste to produce xylose, under both single individual culture and its consortia. The xylose release from the cultures were measured using DNS tests followed by HPLC determination. The results showed that the single microbial culture of B. subtilis, A. pullulans, and P. janczewskii was able to produce xylose released into the culture broth which was 75.06, 81.72, and 82.00 ppm respectively, indicating the xylanolytic enzymes activities from this microorganism which have the ability to convert xylan into xylose. Unexpectedly, all the mix culture of these microbial consortia were unable to produce higher xylose, the amount of xylose released were even lower became 63.11 ppm only when B. subtilis, A. pullulans, and P. janczewskii worked together in a simultaneous culture. This finding indicated that these three microorganisms might not be able to hydrolysed the xylan synergistically. Keywords: bioconversion, lignocellulosic material, microbial consortia, xylanolytic enzyme

Abstract

Tomato fruit (Lycopersicum esculentum Mill.) is a food material with a high water content so it is easy to decompose. This shows that efforts to prevent reduction in food quality can be developed in the form of edible coating from aloe vera gel with concentration of 0%, 30%, 40%, and 50%, and carrageenan with concentration of 1%, 2%, and 3%. The aims of this research were to determine the concentration of aloe vera gel and carrageenan based on the characteristics of edible film and to determine the effect of edible coating and storage time on the quality of tomato. The first stage of this research is making edible film based on analysis parameters such as water vapor transmission rate (WVTR), tensile strength, elongation, and thickness. The selected concentration used in the second stage of this research for making edible coating was 40% of aloe vera gel and 3% of carrageenan. The selected concentration has a WVTR value of 1.758±0.20 g.mm/m2.hour, tensile strength value of 0.248±0.00 N/cm2, elongation value of 25.164±0.10%, and thickness value of 0.074±0.00 mm. Tomato samples coated with edible coating and control tomatoes is stored for 9 days at room temperature (24-25oC and 65–70% relative humidity aproximately) and samples are analyzed every 3 days based on analysis parameters such as vitamin C content, weight loss, hardness level, pH, ohue, lycopene content, and total dissolved solids value. The application of edible coating and storage time can inhibit the decrease of vitamin C levels, lycopene levels, weight loss, hardness, also can inhibit the increase in pH value and total dissolved solids value. Meanwhile, the change in color (hue) of tomato is not affect by the use of edible coating. Keywords: aloe vera, carrageenan, edible coating, storage time, tomato

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
