Abstract

The traditional electrical outlet has evolved with the emergence of "smart plugs," which are WiFi-based devices controlled through communication networks. Many innovations and studies have explored the use of smart plugs for remote load control via the internet and some even utilize renewable energy sources like solar power. In this research, we present a smart plug equipped with a QR code control feature, allowing users to manage connected loads efficiently. Additionally, the smart plug includes sensors to measure power consumption, displaying real- time data on the connected devices. Our smart plug system incorporates an ESP32 microcontroller as the core unit and ACS712 and ZMPT101B sensors for electric current and voltage measurements, respectively. The parameters calculated are electric current and voltage, enabling users to monitor energy consumption accurately. Through rigorous testing, we evaluate the accuracy of the ACS712 and ZMPT101B sensors. The results indicate a 11,39% error for electric current measurements using the ACS712 sensor and a 0,022% error for voltage measurements with the ZMPT101B sensor. This research introduces an innovative smart plug that allows control via a QR code and provides real-time power and load information.

Abstract

Agriculture plays a crucial role in fulfilling global food needs and promoting societal well-being. Soybean cultivation, as a strategic food crop, offers essential protein sources for humans and livestock while enhancing soil fertility through nitrogen fixation. However, the increasing global demand for soybeans poses challenges for farmers, particularly in terms of cultivation efficiency. These challenges are further exacerbated by climate change, land use, disease threats, and commodity price fluctuations. The advancement of agricultural technology, such as IoT, remote sensing, artificial intelligence, and predictive modeling, holds significant promise in improving soybean cultivation's efficiency and productivity. Precision agriculture emerges as a pivotal approach to support agricultural efficiency, productivity, and profitability. Expert systems and image processing techniques like artificial neural networks and genetic algorithms play a vital role in implementing precision agriculture. Information technology's use in precision agriculture focuses on data collection, analysis, and application in farming. Despite considerable research proposing technology integration in soybean cultivation, comprehensive studies on its potential integration remain limited. Thus, this international research aims to analyze the prospects of integrating agricultural technology into plant monitoring systems. Its primary goal is to contribute to the development of sustainable and efficient agricultural practices, considering environmental conditions and natural resource potentials. The findings will serve as a strategic foundation for agricultural stakeholders and policymakers to enhance soybean cultivation's sustainability, productivity, and quality, while effectively addressing global food challenges in the future.

Abstract

Spring, which has the function to help the valve operate so that it can be fully closed and fully open, has a very vital role in the continuous operation of the chemical industry. When a problem occurs, muddy fluid is found in the spring actuator chamber which causes the valve not to operate and not be in full close condition. The purpose of this study is to find the causes of the Spring Actuator failure in the chemical industry. This research was specifically directed at a broken Spring Actuator to determine the cause of the failure/damage. The tests carried out were: fractography, metallography (microstructure), chemical composition analysis, hardness test, and scanning electron microscope (SEM) energy dispersive x-ray (EDX) analysis. The results of the macrographic examination showed that the spring fracture had 2 fracture surface patterns. Spring B has a brittle fracture where the shape of the fracture is more even and does not show residual fracture. While springs A, C, and D experienced ductile fracture. The results of metallography found corrosion products in the surface area of the spring. There are non-metallic inclusions in the form of sulfides and microvoids. The microstructure is tempered martensite. From the results of the chemical composition of the spring material, it still meets the JIS G 4801 grade SUP 12 standard with the addition of Silicon and Chrome. The hardness test results have a hardness value of 518.4 HV. The spring hardness value is above the maximum hardness limit of SUP 12 material. The SEM test results of the spring sample show the presence of non-metallic inclusions with elongated morphology and micro-sized voids. The results of the EDX test showed a Sulfur content of 4.71 wt% in non-metallic inclusions and the content of Fe and O elements in the defective holes which were corrosion products. From this study, it is known that the factors causing damage to the springs are manufacturing process errors, material defects, and corrosive environments.

Abstract

Material coating technology is a method that is often applied to improve the mechanical properties and characteristics of a material. The materials often used in the coating process are metal materials, including medium carbon steel such as AISI 1045, which is often used as machine parts, light pressure gears, pinion forming dies, hydraulic shafts, pump shafts, piston rods. Coating materials vary greatly, this is adjusted to suit needs, such as the SS420 and 95MXC materials used because they have quite high wear resistance and corrosion resistance properties. The composition of the coating material and the strong current in the coating process can affect the quality of the coating results formed on the material. In this research, we will determine the wire with the best results using the wire arc spray method as a coating method to increase the mechanical properties of the PLTU boiler using 95 MXC and SS 420 wire. The highest hardness results were obtained for 95MXC wire with a value of 45.98 HRC. Meanwhile, the hardness value for SS420 wire is 33.11 HRC and the results of microstructure observations also show an increase in thickness of the 95MXC layer with a value of 297.99 ?m in line with the increase in hardness of the coating layer, because in a thicker coating layer the coating material particles will spread evenly and denser, thereby increasing the hardness value
