Soursop fruit (Annona montana Macf.) is one of the plants can be used as as traditional medicine. This plant contains terpenoid and acetogenin which can cause toxicity. The fruit has a flavor that is tasteless so the innovation becomes probiotic drinks. This drink has been proven as an antioxidant, antibacterial, antihyperuricemia and antidiarrheal. The aim of this study was to know about acute toxicity of probiotic drink of soursop juice using brine shrimp lethality test method which will be indicated by LC50 value. This study used experimental methods conducted in the Laboratory of Farmakoknosi. There are several variations in concentration in this study, namely 10000 ppm, 20000 ppm, 30000 ppm, 40000 ppm, 50000 ppm, 60000 ppm, 70000 ppm, 80000 ppm and replication was done 3 times with total number of test animals used was 270. The results showed that probiotic drink of soursop juice can provide acute toxic effects on test animals with LC50 value of 29717,23 ppm. LC50 values ​​indicate that the mountain soursop probiotic drink is not potentially toxic because it has a value of >1000 ppm.

Silver is an important and efficient bactericide. Nanoscale silver has a large specific surface area, high target adhesion, strong permeability and high bactericidal activity. At present, the control of plant bacterial diseases is difficult, and the resistance of plant bacterial pathogens develops rapidly. Silver nanoparticles are expected to become a new generation of agrochemical to control plant bacterial diseases. In this study, a simple and green natural sunlight-induced method was used to prepare carboxymethylcellulose sodium-stabilized silver nanoparticles (CMC-SNs) with a particle size of around 13.53 ± 4.72 nm. CMC-SNs were characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), energy-dispersive spectrometry (EDS), X-ray diffraction (XRD) and UV-vis spectroscopy and found to be spherical and evenly dispersed. The bacteriostatic activity of the CMC-SNs toward Xanthomonas oryzae pv. oryzae (Xoo) was tested. The minimum inhibitory concentration (MIC) of CMC-SNs to Xoo was 1 mg/L, and the minimum bactericidal concentration (MBC) was 2 mg/L. In addition, the antibacterial mechanism was studied by scanning electron microscope (SEM) and confocal laser scanning microscope (CLSM), which confirmed that the CMC-SNs had high antibacterial activity. In order to verify its impact on the environment, we conducted an acute toxicity test on zebrafish and found that Half lethal concentration (LC50) > 100 mg/L in zebrafish, or no acute toxicity. The ability of CMC-SNs to control rice bacterial blight was verified by a pot experiment.

AbstrakToksisitas akut merupakan kemampuan suatu bahan kimia (obat/bahan obat) dalam menimbulkan kerusakan  pada suatu organisme dalam waktu yang relatif singkat. Tujuan penelitian ini adalah untuk mengetahui potensi ketoksikan akut dari ekstrak metanol, fraksi etil asetat dan fraksi air kulit batang ketapang laut (Terminalia catappa L.). Pengujian toksisitas akut dilakukan dengan menggunakan metode BSLT (Brine Shrimp Lethality Test) dan menggunakan analisis program untuk mengetahui nilai LC50 dari ekstrak dan fraksi. Hasil uji toksisitas akut menunjukan nilai LC50  dari ekstrak metanol, fraksi etil asetat dan fraksi air kulit batang ketapang laut (Terminalia catappa L. )  berturut-turut 247,997 ppm; 400,666 ppm dan 618,046 ppm. Hal ini menunjukan bahwa ekstrak metanol batang ketapang laut (Terminalia catappa L.) bersifat paling toksik dibandingkan fraksi etil asetat dan fraksi air.Kata kunci: Ekstrak, Fraksi, Terminalia catappa L., BSLT, Artemia salina LeachAbstractAcute toxicity is the ability of chemical (drug/drug ingredient) to cause damage to organisms in a relatively short time. The purpose of this study was to determine the potential for acute toxicity of methanol extract, ethyl acetate and water fractions of sea ketapang stem skin (Terminalia catappa L.). Acute toxicity testing was performed using the BSLT (Brine Shrimp Lethality Test) method and program analysis to determine the LC50 values of extracts and fractions. The results of the acute toxicity test showed the LC50 values of methanol extract, ethyl acetate and water fractions of the plant stem skin consecutively were 247,997 ppm; 400,666 ppm and 618,046 ppm. This shows that the methanol extract of sea ketapang stems (Terminalia catappa L.) is the most toxic compared to the ethyl acetate and the water fraction.Keywords: Extract, Fraction, Terminalia catappa L., BSLT, Artemia salina Leach
