Abstract

The mangrove apple (Sonneratia caseolarisi) has potential as an alternative food source due to its high nutritional and antioxidant content. This study aims to analyze the effect of storage duration on mangrove apple-based fruit slices' microbiological and chemical quality by adding rosella extract, focusing on Total Plate Count (TPC) value, antioxidant activity, and proximate analysis. The slices were made by adding 50% rosella extract based on the weight of the fruit pulp and were tested during storage at 0, 7, 14, 21, and 28 days. The research methods included TPC testing to count microorganisms, antioxidant activity testing using the DPPH method, and proximate analysis to determine moisture, fat, protein, ash, and carbohydrate content. The results showed that TPC values increased significantly with longer storage time, with the highest increase in the fourth week. Antioxidant activity also decreased over time, indicating the degradation of antioxidant compounds due to oxidation. Proximate testing revealed increased moisture and fat content, while protein, ash, and carbohydrate levels decreased as storage duration increased.

Abstract

The smoked fish industry produces more than 175,522 tons of fish per year, but the technology used is generally simple and relies on hot smoking techniques. The Berkah Abadi Joint Business Group (KUB) is located in Munjungan, Trenggalek Regency, an area bordering the sea and mountains. Initial studies indicate that KUB Berkah Abadi's smoked fish processors face obstacles related to production methods, product sanitation and hygiene, and marketing. The goal of this community service program is to transfer processing technology, improve sanitation and hygiene, and implement vacuum packaging technology to enhance marketing efforts. Twenty participants successfully completed the community service activity. The program began with a survey on liquid smoke and its applications. Then, participants received counseling and practiced smoking fish with liquid smoke technology. Finally, they implemented what they learned by packing smoked fish with a vacuum sealer. The results of the program showed that 90% of the participants increased their knowledge of liquid smoke technology and mastered the vacuum sealer packaging method. They also understood the importance of sanitation and hygiene implementation. Further community service is needed to determine the development of product marketing results after technology implementation.

Abstract

The Pedada fruit (Sonneratia caseolaris) is highly nutritious, containing vitamins A, B, B2, and C and phytochemicals such as flavonoids, steroids, and alkaloids. This study aims to develop Pedada fruit slice jam to enhance the practicality of conventional jam. However, the final product's unattractive color necessitates using natural colorants and bioactive compounds to enhance antioxidant activity. Roselle flower extract (Hibiscus sabdariffa L.), rich in anthocyanins with antioxidant properties, was used as a natural colorant. This research examines the effect of roselle extract on the antioxidant activity and acceptability of Pedada fruit sheet jam using a Completely Randomized Design (CRD) with four treatments: control (without roselle extract), and additions of 30% (P1), 40% (P2), and 50% (P3) roselle extract, each with five replications. Antioxidant activity, hedonic testing, and proximate analysis (carbohydrates, fats, moisture, ash, and protein) were measured. Data analysis was performed using SPSS with one-way ANOVA and Duncan's Multiple Range Test (DMRT) at a 95% significance level. The results show that adding roselle extract significantly enhances antioxidant activity, with the highest IC50 value observed at the 50% treatment (P3) at 25.380 ppm, compared to the control (P0) at 55.429 ppm. Furthermore, the addition of roselle extract improves product acceptability.
