Abstract

The rationale for using medicinal plants or herbs makes their use seen as playing an important role in the prevention and treatment system at the present time. Utilization of medicinal plants in combination is considered more effective and has a higher antibacterial activity compared to a single extract. One of the herbal medicine products from the combination of kencur medicinal plants (Kaempferia galanga) and thatch (Imperata cylindrica) under the name Meddia Meddwa its antibacterial activity has been assessed. This study aims to analyze the effectiveness and antibacterial activity in vitro, and the best concentration from the combination of kencur and kalang in Jamu Meddia Meddwa against Gram positive bacteria ( S. aureus) and Gram negative (A. hydrophila). This study also analyzed the content of active compounds or phytochemicals contained in the combination of kencur and thatch in Meddia Meddwa Medicines. The research method used is a laboratory experimental method. This study uses a single complete randomized design (CRD) with a tukey test. The results showed that the combination of kencur and kalang in Meddia Meddwa herbal medicine had antibacterial activity in vitro. Inhibitory zone diameters for all extract concentrations tested on A. hydrophila and S. aureus significantly different results were obtained (P ≤ 0.05). Gram-positive bacteria (A. hydrophila) effectively inhibits bacterial growth compared to Gram negative bacteria (S. aureus). The content of active compounds contained in the combination of kencur and thatch in simplicia Meddia Meddwa is alkaloids, flavonoids, steroids and phenol hydroquinone. The best concentration of simplicia kencur and thatch in Meddia Meddwa herbal medicine in inhibiting bacterial growth A. hydrophila and S. aureus is 6 ppt.

Abstract

Squid (Loligo sp) is one of the most essential fishery commodities and ranks third after fish and shrimp in commercial fisheries. The freshness of the squid is a very important factor and is closely related to its economic value. One of the actors in the marine commodity storage business at Rebo Beach, Bangka Regency uses Cucumbers to maintain the quality of Squid. Until now there has been no scientific research that proves that Cucumber can be used as a preservative for Squid. For this reason, it is necessary to research to examine the effect of using cucumber at different concentrations and soaking times on the organoleptic assessment of squid quality. This research was conducted in February 2020. The handling process for the Squid was carried out at the Squid shelter in Baturusa, Merawang District, Bangka Regency. In contrast, the organoleptic tests were carried out at the Aquaculture Laboratory of the University of Bangka Belitung. The research was conducted by experimental method. The research variables were differences in the concentration of grated Cucumber and differences in the length of soaking Squid. This study used RAL (Completely Randomized Design) Factorial pattern with 2 factors and 3 replications. Treatment factor by giving grated Cucumber and control or using ice cubes at different times and doses. The soaking times in this study were 24 hours and 48 hours with grated cucumber measurements of 50, 100, and 150 grams per 5 liters of water. Data analysis in this study used the Kruskarwalis test. Squid treated with grated cucumber had the same brightness level as ice cubes after 24 hours of soaking. Giving grated Cucumber does not affect the taste and texture of Squid to the level of people's preferences. Giving grated Cucumber as much as 150 g with 24 hours of soaking time can be accepted by consumers and can compete with Squid which is given ice cube treatment.
