Abstract

It has been realized that the measurement of the Thai type of cassava starch uses a semi-cylindrical capacitor has been done. This measurement is carried out by providing an input signal to the semi-cylindrical capacitor plate using the IC XR-2206 oscillator with a frequency of 100 kHz. The output signal from the capacitor is in the form of an AC voltage which is then forwarded to the full wave rectifier circuit. The output voltage of the rectifier is a DC voltage, and the results are displayed using a DSO oscilloscope. Cassava starch content was measured by the specific gravity method, and the stress was measured using a semi-cylindrical capacitor. In measuring the starch content, the starch content was 19.12 - 28.76% (range 9.64%) and gave an output voltage of 7.53 - 7.89 V (range 0.36 V). Using the linear regression method, the characteristic equation V = 0.035 KP + 6.871, and the correlation value was equals to 0.985.

Abstract

It has been done a variation of CaCO 3, which is 0.95; 1.00; 1.05; and 1,10, through phase formation of BSCCO-2212 superconductor using a wet-mixing method. Samples were dissolved with HNO 3 and distilled by water slowly until the color was clean blue, then gradually dried out at temperatures of 300, 400, and 600 °C. The samples were calcined for 10 hours at 800°C and sintered at 820°C for 20 hours. The XRD's characterization results show that the highest volume fraction was 76.65% in the Ca 1.05 sample. The lowest volume fraction was 49.85% in the Ca 1.10 sample. Meanwhile, the highest degree of orientation was 44.27% in the Ca 1.00 sample, and the lowest degree of orientation was 8.58% in the Ca 1.10 sample. SEM's characterization shows that all samples have been oriented and relatively little space between slabs (voids).

Abstract

The design of the kWh meter token activator using the SG90 Servo Motor based on the Arduino Uno microcontroller has been studied. The tools and materials used are the SG90 Servo Motor, PCA9685 Servo Motor Driver, Arduino Uno, 5V 1 A Adapter, pressure wire, and additional supporting tools. When pushing the kWh meter keypad, a servo motor at a 90° angle causes the wire to travel ideally perpendicularly. When the token value is entered into the interface, Arduino Uno executes the token value and tells the PCA9685 Servo Motor Driver to operate eleven SG90 Servo Motors to drive the push wire for the kWh meter keypad. The precision of the token number on the kWh meter and the display of the word "true" on the LCD kWh meter demonstrate the tool's effectiveness. The kWh meter Token Activator Tool successfully activated five new kWh meter Tokens with 100% correctness in terms of numbers, and each token took 44 seconds to activate. They are making an error and wasting time activating the kWh meter token.

Abstract

Styrofoam has many negative impacts because it harms health, pollutes the environment, and cannot decompose in nature. Efforts have been made to develop biofoam derived from natural kinds of stuff to reduce the harmful effects of styrofoam. So that they are safer and do not pollute the environment. Biofoam in this study was made from tapioca starch, corncob fiber, a binding polymer in the form of Polyvinyl Alcohol (PVA), and a superhydrophobic agent in the form of silica aerogel. This research was conducted to determine the effect of variations in the composition of corncob fiber on the physical properties of biofoam with the addition of silica aerogel. The production of corncob fiber was carried out in two stages, namely using 10% NaOH to remove lignin and bleaching using 10% H2O2 to bleach the fibers, which were then combined into the biofoam mixture. The production of biofoam used the thermopressing method with a temperature of 150° and pressed for 4 minutes with fiber variations of 13.75g, 16.25g, 18.75g, and 21.25g. Add conclusion of the research is 18.75 g of fiber with a water absorption value of (1.2 ± 0.2)%, a density of (0.5 ± 0.1)g/cm3, and a compressive strength of 3.60 MPa.

Abstract

The research of effect of immersion time on the corrosion rate of St37 carbon steel has been conducted in a 3% NaCl corrosive medium using a hibiscus leaves extract inhibitor. The samples of carbon steel St37 were immersed in a corrosive medium of NaCl 3% without being given and given the inhibitor of hibiscus leaf extract with a concentration of 15% for 3, 6, 9, and 12 days. Calculation of reduction in corrosion rate is carried out by the weight loss method. The results showed that adding the hibiscus leaves extract inhibitor effectively reduced the sample's corrosion rate with the most excellent efficiency at nine days immersion, which was equal to 78,48%. The results of XRD characterization show that the phase formed is pure Fe is a corrosion product. The results of SEM characterization showed that the surface microstructure of the sample after immersion was cracks, holes, and lumps, which indicated that the sample had been corroded. The results of EDS characterization show that in the soaked sample, there were corrosion products in the form of FeO compounds whose magnitude increased with every immersion.

Abstract

The aim of this study was to investigate the influence of varying concentrations of Terminalia catappa fruit peel extract on the corrosion rate during immersion periods of 2 days, 4 days, and 6 days for ASTM A36 steel. The ASTM A36 steel specimens were immersed in a corrosive medium containing 2% NaCl, with inhibitor compositions of 0%V, 1%V, 2%V, and 3%V being tested. Measurement results revealed that as the concentration of Terminalia catappa fruit peel extract increased, the corrosion rate proportionally decreased. The lowest corrosion rate was observed in samples with a 3%V inhibitor composition, subjected to a 4-day immersion, measuring at 0.02321 mmpy. Moreover, with the augmentation of fruit peel extract concentration, inhibition efficiency exhibited an augmented trend (83.02% for the 3%V composition, and the lowest at 41.84% for the 1%V composition).
