Spices have always been a part of Indonesia's culinary culture. One of the spices that has high economic value and efficacy is galangal. Therefore, testing of bioactive compounds and the effect of making shredded spice fish with the addition of various concentrations of galangal needs to be further investigated in terms of sensory quality and financial feasibility. This study aims to determine the bioactive components in galangal spice, determine the best concentration of galangal addition in shredded spiced fish products, and determine the financial feasibility. The research was conducted by making galangal spice and shredded spiced fish at IDAEZ Group MSMEs. Subsequently, the galangal spice was tested for bioactive compound (GC-MS) and then, sensory tests were carried out on shredded fish spices mixed with galangal spices (1%, 2%, 3%). After that, the financial feasibility analysis was calculated. The results obtained showed that there were four main components in galangal spice, such as 5-Eicosenen, (E)-, n-Hexadecanoic acid, oleic acid, and 9-Octadecenoic acid (Z)-, oxiranylmethyl ester. Meanwhile, the best concentration of shredded spice fish was found in treatment P3 (addition of 3% galangal). Lastly, the shredded spice fish was found to be viable with an income of IDR 427,547 per production. Keywords: Financial feasibility, GC-MS, Galangal, Sensory.

This study was aimed to determine the effect of tapioca flour and Bogor taro flour formulation on the chemical, physical, and sensory characteristics of catfish sausage and to determine the best formulation. This study was arranged in a Randomized Complete Group Design (RCGD) with a single factor of tapioca flour and Bogor taro flour formulation with 6 treatments P1 (100%:0%), P2 (80%:20%), P3 (60%:40%), P4 (40%:60%), P5 (20%:80%), and P6 (0%:100%) with 4 replications. Data were tested for equality of variance with Barlett's test and data saturation with Tuckey's test. The data were analyzed for variance to determine the effect between treatments, then further analyzed using the HSD test at the 5% level. The results showed that the formulation of tapioca flour and Bogor taro flour had a very significant on water content, ash content, hardness, springiness, cohesiveness, appearance, and overall acceptance but no effect on the taste and aroma of catfish sausage. P5 was the best treatment with a water content of 52.08%, ash content of 1.55%, hardness of 270.75 gf, springiness of 10.03 mm, cohesiveness of 0.83, appearance of 2.93 (slightly dull), taste of 3.87 (typical of fish), aroma of 3.87 (typical of fish), overall acceptance of 3.88 (like), protein content of 15.61%, and fat content of 4.29%.

Gotu cola leaf chips produced by the Women Farmers Group in the city of Pagar Alam, South Sumatra are packaged using polypropylene plastic packaging and the shelf life is not yet known, so a test is needed to estimate the shelf life of the gotu kola leaf chips produced by KWT. This research aims to determine the shelf life of gotu kola leaf chips in polypropylene packaging using the Arrhenius model ASLT (Accelerated Shelf Life Test). The study was structured descriptively with two replications. The chips made from gotu kola leaves were stored at temperatures of 30 C, 35 C, and 40 °C in polypropylene (PP) packaging.with a thickness of 0.08 mm for one month (28 days). Observations were made on the parameters of water content, free fatty acid levels, and sensory (color, aroma, and texture of gotu kola leaf chips) once a week, namely on days 0, 7, 14, 21, and 28. Determined the shelf life of gotu kola leaf chips using the ASLT model with Microsoft Excel 2010 software. The results showed that gotu kola leaf chips in polypropylene packaging at 30 °C had a shelf life of 76.67 days (2.57 months) on the zero order of the Arrhenius model ASLT method.

Rizal S, Suharyono AS, Astuti S, Dewanti AS, Nugroho YB. 2024. The effect of kweni mango and randu honey addition on the characteristics of synbiotic etawa goat milk. Biodiversitas 25: 1580-1587. The addition of kweni mango and randu honey as ingredients for producing synbiotic etawa goat milk is widely known to have a significant effect on the characteristics of the product. Therefore, this study aimed to identify the best formulation of kweni mango and randu honey in producing synbiotic etawa goat milk. The experiment was conducted using a completely randomized block design with 4 replications. A single factor with six levels of formulations of kweni mango extract and randu honey was used in producing synbiotic etawa goat milk. These formulations included F1 (0%:25%), F2 (5%:20%), F3 (10%:15%), F4 (15%:10%), F5 (20%:5%), and F6 (25%:0%). Subsequently, the microbiological, chemical, and sensory properties, as well as antimicrobial activity of the product were evaluated. The data obtained were statistically analyzed using ANOVA and the Least Significant Difference (LSD) test at a 5% significance level. The results showed that formulation (F4) containing 15% kweni mango extract and 10% randu honey produced the best synbiotic Etawa goat milk beverage. In addition, F4 formulation showed higher antibacterial activity against Staphylococcus aureus than Escherichia coli. The optimal beverage met the standards for lactic fermentation products from a chemical perspective and was favored by the panelists.

Pumpkin flour is a processed product high in carotenoids and a good source of nutrients. This nutritional content of pumpkin flour was considered to be influenced by the fruit maturity stage. Therefore, this research aimed to evaluate pumpkin flour's chemical properties, bioactive components, and antioxidant activity at different maturity stages. This also used honey pumpkins with a maturity stage of 15, 20,25, and 30 days after fruit set( DAFS). The results showed that the maturity stage of butternut pumpkin affects the moisture content and bioactive components such as phenols, flavonoids, and carotenoids of flour produced. Furthermore, the highest antioxidant activity was found in pumpkin flour with a maturity stage of 25 DAFS with IC50 values of 85.31 µg/mL (DPPH) and 64.39 g/mL (ABTS). Therefore, butternut pumpkins with a maturity stage of 25 DAFS can be processed into flour with antioxidant properties.
