“…Characterization of liquids using ultrasonic techniques has attracted attention because they are non-destructive, fast, minimally invasive, and technically well-established worldwide for a long time [31] , [50] , [51] , [52] . The biodiesel produced was characterized by a study of ultrasonic velocity behavior with the temperature increasing in a range of 20 °C to 50 °C.…”

“…Untuk mengetahui karakteristik suatu bahan bakar diperlukan suatu metode nondestructive yang kuat dan akurat, sensor ultrasonik menjadi pilihan untuk melakukan penelitian ini [8]. Metode menggunakan sensor ultrasonik memiliki tingkat penetrasi yang kuat yang kemudian membuat sampel uji tidak akan rusak sehingga akan menghasilkan nilai keluaran yang baik dan dapat memproses hasilnya dengan cepat.…”

The need for fuel oil has increased along with the increase of population, the number of vehicles and industries. An increase in demand for fuel oil is used by some people to make a profit by selling mixed fuel oil at the same price as the price set by the government. The purpose of this study is to create a prototype device that can characterize the type of fuel oil and create a classification system to determine the level of fuel purity with 40 kHz ultrasonic waves based on the parameters of wave velocity using the K-Nearest Neighbor (KNN) algorithm.This device works by using a 40 kHz ultrasonic wave that is connected to an ultrasonic transmitter. The propagated wave will be received by the ultrasonic receiver. The wave received by the receiver will be amplified and connected to the comparator circuit so that it can be processed by a microcontroller. Data obtained using this tool are wave travel time, wave velocity, density, and attenuation. The data used for classification systems using the KNN algorithm is wave velocity.Classification using the KNN algorithm can identify the level of fuel purity based on the parameters of the wave velocity obtained from ultrasonic wave gauges with an accuracy of 72.50%. Wave velocity which is measured using ultrasonic waves is directly proportional to the actual speed with the largest percentage of deviations that is 0.34%.

Ultrasound has been widely used as a technological alternative way to analyse noninvasively an assortment of materials. It includes liquids with dissimilar physical characteristics, including mono-and multi-phasic mixtures, suspension formation and dissolution, in-line processing, among other practical applications. Regardless the huge spread of uses, so far ultrasound has not been proved to be able to quantify transesterification kinetics with a metrological approach. The aim of this chapter is to demonstrate that a properly designed ultrasonic experiment can be developed to identify remarkable stages of a transesterification reaction to produce biodiesel. The method was compared both with gas chromatography and hydrogen nuclear magnetic resonance ( 1 H NMR). For an in-line application, ultrasound has been proved to work properly as a monitoring tool for chemical reaction kinetics.
