Abstract

Non-steroidal anti-inflammatory drugs (NSAIDs) commonly used have associated side effects, necessitating the search for safer alternatives based on natural ingredients. This study aims to evaluate the effectiveness of a 70% ethanol extract emulgel of mulberry leaves (Morus alba L.) as an anti-inflammatory agent. The methodology employed is an experimental study involving the formulation of emulgel, which was tested on Wistar rats. The extraction process utilized maceration of mulberry leaves with 70% ethanol, yielding a concentrated extract that was then formulated into an emulgel. Anti-inflammatory activity was assessed using carrageenan induction and measuring edema volume in the test animals. The results indicated that the mulberry leaf extract emulgel exhibited significant anti-inflammatory activity, with a p-value of <0.023, demonstrating a meaningful difference compared to the positive control. The formula with a concentration of 0.32% showed the best efficacy at 180 minutes. The conclusion of this study highlights the potential of the 70% ethanol extract emulgel of mulberry leaves as a safe and effective alternative for anti-inflammatory therapy, recommending further safety testing to ensure its safe use in the community.

Abstract

Chicken meat is a source of animal protein that can be processed into various food products, including jerky, offering a more economical alternative without compromising taste and quality, although it has the drawback of less appealing color. This study aims to determine the optimal concentration of angkak (Monascus purpureus) as a safe natural colorant to enhance the color of minced chicken jerky and evaluate the effects of angkak concentration and oven temperature on its physicochemical properties, total plate count (TPC), and organoleptic characteristics. The study used a Completely Randomized Design (CRD) with four treatments combining angkak concentrations (1% and 3%) and oven temperatures (80°C and 100°C), each replicated three times. The analyzed parameters included color (L, a, b), moisture content, protein content, TPC, and organoleptic properties (taste, color, aroma, texture). The results of the study showed that adding angkak significantly increased red color intensity and antibacterial activity, while oven temperature affected moisture and protein contents. The best treatment was found at 3% angkak concentration and 100°C oven temperature, yielding dark red color, protein content of 27.13–30.06%, TPC of 0.022 x 10⁵ CFU/g, and high organoleptic acceptance. Thus, angkak canibe usedtas asnatural colorant and preservativeKfor minced chicken jerky.

Abstract

Seed priming is a technique for treating seeds before germination to improve the quality of the plants produced. Seed priming can be done by soaking the seeds in various solutions, including hormone solutions. Groundnut (Arachis hypogaea L.) is the second most important commodity in Indonesia for both common and striated groundnut. This research aims to determine the effect of seed priming using the hormone gibberellic acid on the vegetative growth of peanuts and striated peanuts. This research used a completely randomized design with a factorial pattern; the first factor is variation in the type of peanut; The second factor is the variation in gibberellic acid concentration for seed priming, namely 0 ppm (only distilled water), 100 ppm, 200 ppm, 300 ppm and 400 ppm and without priming. Each treatment was carried out in 3 repetitions. The variables observed were plant wet weight, plant dry weight, chlorophyll content, number of leaves, shoot:root ratio. Quantitative data were analyzed using Analysis of Variance (ANOVA) and DMRT with a confidence level of 95%. The results of the research showed that seed priming treatment using the gibberellic acid hormone had a significant effect on the wet weight and dry weight of the plants; shoot:root ratio, and chlorophyll content of peanut and striated peanut leaves. Seed priming treatment using the hormone gibberellic acid had no significant effect on the number of leaves of ordinary peanuts and striated peanuts.

Abstract

Avocado juice is one of the most popular preparations in the community, but avocado fruit is seasonal so that when it is not in season it becomes difficult to obtain or even unavailable, so it is necessary to seek alternative juices with flavors similar to avocado juice. One alternative is juice made from a mixture of cassava tape and pakcoy leaves. This study aims to determine how the proportion of cassava tape and pakcoy affects the chemical and organoleptic quality of the resulting product, and to determine the most optimal proportion to produce the best juice product similar to avocado juice. This study used a quantitative experimental laboratory method with a research design using a Completely Randomized Design with four treatments and three repetitions. Chemical test parameters include reducing sugar reduction with luff-schrool test method, crude fiber with gravimetric test method, vitamin C with iodimetry test. The organoleptic test (taste, aroma, and color) using 25 panelists. Data analysis used Duncan test for lab test results and Kruskal Wallis for organoleptic test. The results showed that (1) the proportion of cassava and pakcoy tape had a significant effect on reducing sugar content, fiber content, and vitamin C content. (2) Reducing sugar content, fiber content, and vitamin C content in cassava and pakcoy tape juice were higher than avocado juice. (3) Organoleptic test showed the best value in treatment J3 in the aspects of taste and color, and treatment J0 in the aspect of aroma.
