Abstract

During the Covid-19 pandemic, people began to maintain their health, by using herbal medicine as an alternative treatment. One type of herbal medicine used is jamu beras kencur because it has properties to increase stamina, increase appetite, and relieve aches and cough disorders. In the Regulation of the Minister of Health of the Republic of Indonesia No. 007 of 2012 carrying herbs such as jamu beras kencur does not require marketing authorization. The quality of the herbal medicine produced has not been confirmed as feasible from microbial contamination, especially in molds, the number of yeast molds in the jamu beras kencur must comply with BPOM standards Number 32 of 2019 namely AKK <103 colonies/mL. This study aimed to determine the effect of the storage time of jamu beras kencur on mold growth with storage treatments of 0 hours, 4 hours, 8 hours, 12 hours, and 24 hours at room temperature. This type of research is a Quasi Experiment with a research design of One Group Pretest-Postest Design. The results of this study showed that the average AKK value was 0 hours 0.2x100 colonies/mL, 4 hours 0.4x100 colonies/mL, 8 hours 0.4x100 colonies/mL. 12 hours 0.8x100 colonies/mL and 24 hours 2.2x100 colonies/mL. These results stated that the jamu beras kencur met the BPOM standard requirements Number 32 of 2019 which was AKK <103 Colonies/mL. The results of the Kruskal Wallis test obtained a sig value of 0.286, it was concluded that there was no effect of storage time for the jamu beras kencur on the growth of molds. The identification results on the jamu beras kencur obtained fungal species, namely Aspergillus flavus, Aspergillus niger, and Penicillium sp. Suggestions for further researchers can examine the effect of storage time on mold growth in other types of herbal medicine.

Abstract

Cardiovascular disease is a leading cause of death worldwide, with thrombosis playing a key role in the pathological process. Conventional antithrombotic therapy often causes side effects, necessitating alternatives based on biological resources. Marine microorganisms are known to produce fibrinolytic protease enzymes that can degrade fibrin and prevent blood clot formation. This study aimed to evaluate the differences in antithrombotic activity and hemolysis patterns of fibrinolytic protease-producing bacterial isolates obtained from the coast of Tanjung Dewa Beach, South Kalimantan. A total of 15 isolates were obtained from seawater, beach sand, mollusks, crabs, and barnacles, and then subjected to colony morphology identification, Gram staining, and spore observation. Proteolytic activity testing using Skim Milk Agar media showed that all isolates had proteolytic activity with varying indices, with PSR1 showing the highest index (3.4). Furthermore, fibrinolytic testing using the fibrin plate assay method showed that 10 isolates were capable of degrading fibrin, with AL8 and SP2 showing the highest fibrinolytic indices (3.12 and 3.11, respectively). Antithrombotic testing using the clot lysis method revealed that AL7 and SP1 exhibited the highest lysis percentages (82.05% and 88.88%, respectively). Anticoagulant activity, as determined by the Lee-White method, showed that SP2 significantly prolonged the coagulation time (142 seconds, 49.65%). Hemolysis pattern testing revealed variations in activity, with AL8 and PSR1 classified as gamma-hemolytic and therefore potentially safer. Statistical analysis showed no significant differences between isolates in terms of antithrombotic activity, anticoagulant activity, or hemolysis pattern (p > 0.05). These findings suggest that coastal bacterial isolates from Tanjung Dewa Beach, particularly AL8 and SP2, have the potential to serve as safe, natural antithrombotic agents, supporting the development of biomedical therapies for cardiovascular disease.
