Abstract

The increase in electrical energy demand occurs due to high population growth, but this is not balanced with the increase in the supply of electrical energy, the installed power capacity remains the same, while community needs continue to increase. PLTMH (Microhydro Power Plant) and PLTB (Wind Power Plant) are power plants with renewable energy sources. This is seen from an economic and security perspective. Because currently fossil energy reserves are decreasing while the need for fuel consumption continues to increase, this has an impact on the energy crisis. PLTB has the main advantage because of its renewable nature. This means that exploitation of this energy source will not reduce wind resources like the use of fossil fuels. Based on considerations for the fulfillment of electrical energy, an economical, safe and reliable generator was built.

Abstract

Thin plates are a common material used in the automotive industry for vehicle panels. Galvanized metal materials are typically selected for use in vehicle panel construction due to their ductile nature, malleability, and resistance to corrosion. The function of vehicle panels is of great consequence with regard to the safety and comfort of the vehicle. The level of comfort experienced by vehicle occupants is influenced by noise, which is a consequence of vibrations generated by the engine and the road surface. The detrimental effects of excessive vibration can be mitigated by enhancing the rigidity of the panel. One method of achieving this is through the formation of a groove profile on the panel's surface, utilizing a bead roll process. The objective of this study is to ascertain the impact of variations in the width and depth of the groove, with a trapezoidal shape, on the stiffness of 0.6 mm thick galvanized plates for natural frequency response. The research method entailed the creation of an experimental design, the formation of a groove profile through the bead roll process, and the subsequent natural frequency testing of the plates using a Vibroport 80. The results of this testing were then subjected to analysis. The findings indicated that the variation in groove width and depth had no discernible impact on the plate stiffness with respect to the natural frequency response.

Abstract

The cold forming process for thin plates is widely used and essential in the manufacturing industry, particularly in the automotive sector. One such cold-forming method is the bead roll process, commonly referred to as "Bead Roll." This process is popular due to its low cost and its ability to improve vibration resistance effectively. The "Bead Roller" machine is used to create grooves or profiles on sheet metal plates. Based on experimental analysis of the collected data, the plate with the best damping capability was found to be the one processed using a roll width of 10 mm and a rolling depth of 3 mm. This research is expected to expand knowledge about plates as an innovative new form and serve as a reference for future research and development

Abstract

Turmeric is one of the spices that has many health benefits so that it is widely consumed by humans, both for cooking spices, health therapy, and traditional cosmetics. Therefore, drying turmeric is one way to preserve turmeric so that it can be used for a long time. The purpose of this study was to analyze the properties or characteristics of turmeric drying using an automatic rotary drying machine. The Artificial Neural Network-Fuzzy Logic (ANN-FL) method was developed to model the relationship between drying parameters such as turmeric silage slice thickness, drying temperature, air flow rate, and drying time to the remaining water content and air humidity ratio. The first experiment showed a remaining water content of 10% from the initial water content of 75% with a final humidity of 40%. The second and third experiments showed water content to be 8% and 5% respectively from the initial water content of 80 and 85% with humidity of 30% and 15%. Artificial Neural Network (ANN) and Fuzzy Logic (FL) were modeled to learn patterns from experimental data obtained through experiments. The histogram of the model error shows that the distribution of errors between predictions and targets. Most of the errors are close to zero, indicating that the ANN-FL model has an accurate prediction rate. In addition, the training performance shows a decrease in Mean Squared Error (MSE) as the number of epochs increases, which means that the ANN-FL model learns well and reduces the prediction error as the number of epochs increases. The results of the study indicate that the ANN-FL method can be used to predict the water content of turmeric with a high level of accuracy. In addition, the ANN-FL method can also be used to control the temperature and humidity of turmeric drying so that more uniform and high-quality drying results are obtained.

Abstract

Steel is one of the most widely used types of metal in the engineering field. There are many types of steel materials with different properties and characteristics, and steel materials can be used depending on their purpose. Steel contains various alloying elements. Although carbon is the element that has the greatest influence on the properties of steel, other elements cannot be ignored. The carbon content affects the mechanical properties of steel, such as hardness, ductility, formability, and other mechanical properties. This study aims to evaluate whether VCN 150 alloy steel can be used as an alternative material for cutting blades in plastic shredding machines based on its hardness value. The heat treatment process is conducted using varying temperatures of 800°C, 840°C, and 880°C, as well as using different cooling media, namely oil, seawater, and saltwater (25% salt content), then followed by a tempering process at temperatures of 100°C and 150°C. The research results indicate that the cooling medium significantly affects the hardness value of the material. A combination of a temperature of 800 °C and seawater cooling produces the maximum hardness value. The increase in hardness value becomes an alternative potential for plastic cutting blades.

Abstract

The manufacturing industry, particularly in the automotive sector, galvanized steel sheets are commonly used due to their strong durability and high rigidity, making them suitable as structural components for vehicle bodies. However, the rigidity of galvanized steel sheets can be affected when formed under cold conditions. Therefore, this study aims to investigate the impact of cold forming on the natural frequency of 0.8 mm thick galvanized steel sheets. Using the Vibroport 80 device, the sheets were formed into cross grooves and then clamped onto a test fixture as part of the testing procedure. Taguchi's method was employed to analyze the data. Based on the research results using Taguchi, the Signal-to-Noise (S/N) ratio for stiffness with the "Smaller Is Better" criterion revealed that the optimal groove profile, for maximum frequency response, had a width of 12 mm, depth of 3 mm, and a frequency value of 52.45 Hz. No significant process variables or parameters were found to have a substantial impact on the stiffness or natural frequency response of the formed sheet.

Abstract

The Indonesian government recognizes the importance of transitioning away from dependence on fossil fuels. Briquettes are becoming the most popular option for overcoming fossil fuel dependence. This study examines the effect of the drying process and variation of anthracite mixture with wood sawdust on ash content and volatile matter in briquettes. The study used a factorial method with three process variables: water and molasses fractions, temperature, and holding time. The results showed that the highest ash content was obtained in briquettes with a water and molasses fraction of 1:1, while the lowest ash content was at a fraction of 2:1. The temperature and drying time also affected the ash content, where lower temperature and longer drying time resulted in lower ash content. Regarding volatile matter, briquettes with a drying temperature of 120°C and a drying time of 60 minutes produced the lowest volatile matter content. This study concludes that combining the drying process and the right mix of ingredients can improve the quality of briquettes, although the results obtained have not met the established SNI standards.
