Abstract

Aquaculture faces serious threats, one of which is infectious disease caused by Vibrio parahaemolyticus bacteria. These bacteria have shown antibiotic resistance and cause significant economic losses. The need for safe and sustainable antibacterial alternatives is crucial given the negative impact of using synthetic antibiotics. This review explores the potential of Shorea beccariana, Uncaria gambir, and Swietenia macrophylla as natural antibacterial agents against Vibrio parahaemolyticus. A systematic descriptive study method was used to integrate primary literature. Results showed that V. parahaemolyticus is a pathogenic Gram-negative bacterium with a complex virulence mechanism. Various studies have confirmed the antibacterial activity of plant secondary metabolites, such as flavonoids, tannins, and terpenoids, against Vibrio spp. Although the specific effectiveness of these three plants against V. parahaemolyticus has not been widely studied, the bioactive compounds identified in their extracts show strong potential. These compounds work by damaging the integrity of bacterial cells and disrupting their metabolism, offering a promising natural solution for vibriosis control.

Abstract

Vibrio parahaemolyticus infection poses a significant challenge in intensive shrimp culture, leading to substantial economic losses. Its common treatments using synthetic antibiotics have been linked to increased risks of antibiotic resistance and residual effects. Therefore, finding environmentally safe and effective natural alternatives is deemed essential. Tengkawang Bukit (Shorea beccariana) stem extract contains antibacterial compounds, including asiatic acid, oleanolic acid, and lupanone, all classified as terpenoids. This study aims to evaluate the antibacterial potential of S. beccariana stem extract through phytochemical screening and a disc diffusion test against V. parahaemolyticus. The screening results confirmed the presence of bioactive compounds, including alkaloids, flavonoids, saponins, tannins, and steroids. The disc diffusion test showed an increase in the inhibition zone with increasing extract concentration, with inhibition diameters ranging from 9.04 ± 0.48 mm to 10.75 ± 0.26 mm. The 17% extract yield indicates a high availability of active compounds. These findings suggest that tengkawang bukit stem extract has potential as a natural antibacterial alternative for controlling V. parahaemolyticus in shrimp culture. This approach could help reduce reliance on synthetic antibiotics and promote sustainable fisheries. Infeksi Vibrio parahaemolyticus merupakan salah satu kendala utama dalam budidaya udang yang menyebabkan kerugian ekonomi signifikan. Penggunaan antibiotik sintetis sebagai pengobatan telah menimbulkan kekhawatiran terkait resistensi dan residu, sehingga diperlukan alternatif alami yang aman dan efektif. Batang tengkawang bukit (Shorea beccariana) diketahui mengandung senyawa antibakteri seperti asam asiatik, asam oleanolik, dan lupanon yang tergolong ke dalam senyawa terpenoid. Studi ini bertujuan untuk mengevaluasi potensi antibakteri ekstrak batang S. beccariana melalui skrining fitokimia dan uji difusi cakram terhadap V. parahaemolyticus. Hasil skrining menunjukkan adanya kandungan senyawa bioaktif berupa alkaloid, flavonoid, saponin, tanin, dan steroid. Uji difusi cakram memperlihatkan zona hambat yang meningkat seiring dengan peningkatan konsentrasi ekstrak, dengan diameter hambatan berkisar 9,04 ± 0,48 mm hingga 10,75 ± 0,26 mm. Rendemen ekstrak sebesar 17% menunjukkan ketersediaan senyawa aktif yang melimpah. Hasil riset ini mengindikasikan bahwa ekstrak batang tengkawang bukit berpotensi sebagai alternatif antibakteri alami dalam pengendalian V. parahaemolyticus pada budidaya udang, sehingga dapat mengurangi ketergantungan terhadap antibiotik sintetis dan mendukung keberlanjutan perikanan.
