Abstract

Corrosion is the degradation of metal quality caused by a reaction between the environment and the material. Generally, corrosion problems are caused by water. However, there are several factors other than water that influence the corrosion rate, such as temperature. An increase in temperature in a corrosive system will increase the rate of corrosion. This is caused by an increase in the active energy of the particles involved in the corrosion reaction. The aim of this research was to determine the effect of temperature and firing time on the corrosion rate of ASTM A 572 steel material. The research method used was experimental, using ASTM A 572 steel plates measuring 5 cm wide and 7 cm long with a thickness of 5 mm with the heating process used being 3 hours, 5 hours and 7 hours at temperatures of 600oC, 650oC and 700oC. The results of the research on the effect of temperature and firing time on the corrosion rate of ASTM A 572 steel material showed that the lowest average corrosion value was 0,3947 mm/year with a testing time of 3 hours at a temperature of 600oC. Then the highest average corrosion value was obtained, namely 8,0937 mm/year with a testing time of 7 hours at a temperature of 700oC

Abstract

An incinerator is a machine designed to process solid waste through high-temperature combustion technology. Continuous combustion may lead to corrosion, which is often considered an inevitable problem. The purpose of this study is to investigate how combustion duration and corrosive media affect the corrosion rate. The research method employed was an experimental design involving the heating of material. Tests were conducted to analyze the effect of combustion time and corrosive media in the incinerator chamber on the corrosion rate. The material used was ASTM A36 steel with dimensions of 70 mm × 50 mm × 5 mm. The corrosive media employed were rainwater, H₂SO₄, and HCl. The material was heated at 700 °C for 3, 5, and 7 hours. The immersion time in corrosive media was 30 minutes, followed by a cooling period of 7 days. The results indicated that the highest corrosion rate occurred at a combustion time of 7 hours. Thus, the longer the combustion time, the greater the reaction, resulting in an increased corrosion rate. The use of different corrosive media also influenced the corrosion rate. It was found that the highest corrosion rate was 0.00534 mm/year after 7 hours of heating in HCl solution, while the lowest corrosion rate was approximately 0.00077 mm/year in rainwater after 3 hours of heating. Therefore, prolonged heating not only enhances the reaction but also significantly increases the corrosion rate.

Abstract

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used as an electron donor to TiO2 nanoparticles and uses an electrolyte as an electron transport medium. One of the dye extracts of purple spinach and moringa leaves used as a photosensitizer is chlorophyll extract or anthocyanin. The nature of chlorophyll which is able to absorb light is a function of the dye in DSSC. Making Moringa leaf and red spinach leaf dye after being blended, dried and ground into powder. Then the Moringa leaf powder was mixed with 70% ethanol with the ratio of Moringa leaves and ethanol, namely 1:2, 1:3, and 1:4. Meanwhile, red spinach leaf powder was mixed with ethanol solution in a ratio of 1:3. DSSC fabrication shows that the voltage, current, and power produced increases with the increasing amount of ethanol used, namely 1.879 mW, 1.573 mW, and 1.98 mW. Meanwhile, red spinach leaves mixed with ethanol in a ratio of 1:3 showed that the results were higher than Moringa leaves. So from the results of DSSC Solar Cell fabrication using Moringa leaves and red spinach leaves, it shows that there is light absorption from these materials and an increase in the conductive properties of Moringa and red spinach DSSCs.

Abstract

Fabrication prototype of DSSC (Dye-Sensitized Solar Cell) using mulberry powder from mulberry leaf extract (Morus Alba L.) and dragon fruit (Hylocereus Polyrhizus) as photosensitizers has been carried out. The test was carried out by testing the I-V characteristics at a light distance of 10, 20 and 30 cm from the material sample. The test results show that the chlorophyll of mulberry and dragon fruit is capable of producing an electric current which is a characteristic of the resistance of organic materials. In DSSC with mulberry powder dye, the greatest power was found at a halogen lamp distance of 10 cm with a power of 257.77 mW. Whereas in DSSC with red dragon fruit flesh dye, the greatest power was obtained at 162.35 mW with the halogen lamp distance from the DSSC device being 10 cm. DSSC testing using mulberry powder and dragon fruit showed that the power produced on mulberry powder leaves was higher than dragon fruit. The results of the I-V characteristic test on the DSSC device show a linear graph.

Abstract

Leaf spring is a flat plate component that is clamped together to obtain product efficiency using metal materials, sometimes requiring high hardness and wear resistance. The steel working process is highly dependent on the heat treatment process and the cooling media used to obtain good product quality. The purpose of this study was to determine the effect of variations in temperature and holding time in the process of annealing used leaf springs and trucks on hardness values. This test has been carried out with each variation, namely, temperature 450oC, 550oC, 650oC and held for 30, 60, and 90 minutes as well as the cooling process using air in the heating furnace room. Based on the data obtained, the influence of temperature media and holding time in the Annealing process of used leaf spring dumb trucks has a low hardness value at a temperature of 650°C with a holding time of 30 minutes, 60 minutes and 90 minutes, the lowest hardness value is at 90 minutes, namely 7.7 While the HRC temperature of 550°C and holding time of 90 minutes reaches 26.9HRC, the hardness value is higher and the same as 450°C with holding time of 90 minutes which reaches 30.8HRC. The influence of temperature and holding time on the annealing process of used leaf spring dumb trucks has the lowest hardness value at a temperature of 650°C with a holding time of 90 minutes, namely 7.7 HRC.
