Abstract: Abstract Liquid smoke is an alternative material to replace conventional smoking methods. This study aims to see the physical quality of liquid smoke from wood and leaves of Kusambi and liquid smoke from coconut shells after being given ultrasonic treatment at pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), Oxidation-Reduction Potentials (ORP), Specific Gravity (SG), Colors, and Salinity. This research is a laboratory experiment using Randomized Block Design (RBD) with two types of liquid smoke and five groups of various concentrations of liquid smoke and was carried out for three repetitions. Control treatment using pure aquadest without any mixture with ultrasonic treatment. There are two types of liquid smoke solutions, Kusambi liquid smoke and coconut shell liquid smoke, each of which is grouped into five groups, namely liquid smoke solutions with concentrations of 0%, 1%, 2%, 3%, and 5%. Each sample was treated with an ultrasonic bath at room temperature for 10 min. Data were analyzed using Analysis of Variance (ANOVA). If the data showed a significant difference, it is continued with Duncan Multiple Range Test (DMRT). The average value of pH is 3.91–4.37. Liquid Smoke has acidic compounds, such as acetic acid, propionic acid, butyric acid, and valeric acid, which can affect the pH level of each increase in concentration. The average value of EC is 60.27–237.47 S/cm, the average value of TDS is 30.73–115.73 ppm, the average value of lightness (L*) 23.35–23.50%, the average value of redness (*a) is −4.54%–−3.85%, the average value of yellowness (*b) is 3.34–4.01%, the average value of ORP is 298.07 – 317.73 mv. The SG value for all samples is 1.002, and the average salinity value is 25.73–119.80 ppm. The difference in the concentration of liquid smoke did not have a significant effect (P > 0,05) on the EC, TDS, Color, and SG tests. The difference in the concentration of liquid smoke had a very significant effect (P 0,05) on the Color L* and SG test. However, the different kinds of liquid smoke had a significant effect (P
