Abstract

Wind turbines are typically classified as Horizontal Axis Wind Turbines (HAWT) or Vertical Axis Wind Turbines (VAWT). VAWT has a superior ability to accelerate from rest to rotation than HAWT, allowing it to rotate the rotor even when the wind speed is low; additionally, the produced torque is relatively high. Using the Savonius helix VAWT is one of the numerous methods for enhancing VAWT performance. The effect of the number of blades and the blade twist of the rotor or the angle of rotation of the blades on the rotor from the bottom end to the top end on the speed cut generated by the VAWT Savonius helix was investigated experimentally. Variations in the number of blades used in the study included 2 and 3 blades, as well as 90°, 180°, 270°, and 360° for the rotor twist blades. In a wind tunnel, data was collected at wind speeds ranging from 0 to 5 m/s. The best performance research results were obtained With three blades, a twist angle of 180 degrees, and a cutting speed of 1.51 m/s. By modifying the Savonius Helix VAWT design in this study, it is possible to increase the efficiency and performance of turbines, mainly when used at low wind speeds, and the potential for using wind energy as a more efficient and sustainable alternative energy source.

Abstract

As fossil fuel resources decline, vortex water turbines offer a promising renewable energy alternative by utilizing river flow. This experimental research aims to analyze the effect of blade distance from the outlet and transmission ratio on the electrical power and efficiency produced by vortex water turbines as a renewable energy solution. Three variations of blade distance from the outlet (20 mm, 40 mm, and 60 mm) and three variations of transmission ratio (1:3, 1:4, and 1:5) were tested under seven water flow rate variations of 27.8 l/min, 33.68 l/min, 34.11 l/min, 34.54 l/min, 34.97 l/min, 35.4 l/min, and 35.83 l/min. Data were collected for 5 minutes, with a 10-second interval for each parameter. Test results show that the highest electrical power of 4.88 watts was achieved at a blade distance of 20 mm from the outlet, a transmission ratio of 1:5, and a water flow rate of 35.83 l/min. Meanwhile, the highest turbine efficiency of 11.25% was obtained at a blade distance of 20 mm from the outlet, a transmission ratio of 1:3, and a water flow rate of 35.83 l/min. Increasing blade–outlet distance reduced both power and efficiency, while higher transmission ratios increased power but decreased efficiency due to torque–speed trade-offs. These results confirm that the distance between the blade and the outlet, and the transmission ratio, are critical parameters for optimizing performance of vortex turbines. A blade distance closer to the outlet provides the best performance and a larger transmission ratio will also improve performance, although transmission loading must also be considered.

Abstract

Wooden tenons are crucial components in joinery used in furniture manufacturing. Unfortunately, their production still heavily relies on manual methods, leading to inefficiencies. This research focuses on developing and evaluating an integrated wooden tenon machine to enhance efficiency and productivity in furniture manufacturing. Through quantitative experimental methods, the study compares the speed and capacity of wooden tenon production between manual methods and the integrated machine. Techno-economic analysis is also conducted to assess production feasibility. Experiments take place at UD. Sunarso Mebel using Suren (Toona Sureni) wood with five different size specifications: 3 cm thick, 40 cm long, and varying widths of 6 cm, 9 cm, 12 cm, 14 cm, and 25 cm. Results indicate that the integrated machine boosts wooden tenon production speed by up to 10 times and capacity by up to 9 times compared to manual methods. Additionally, the quality of dowels produced by the machine is superior due to smoother and more precise surfaces. With low production and operational costs, the machine is economically recommended for profit enhancement. The investment in the integrated wooden tenon machine can be recouped within just one month.

Abstract

Speed and accuracy of workmanship are important supporting factors for business actors operating in the service sector. The availability of adequate supporting equipment can increase work productivity and can reduce the risk of work accidents that can endanger the surrounding environment. Technological developments in the automotive industry always provide innovations. Even though it is like that, it still doesn't escape the new problems that accompany it. In the process of replacing a car clutch lining, the application of knowledge about lifting aircraft is very necessary. Differences in the load capacity of car engines that exceed human strength capacity require the use of tools according to specifications. The addition of a hydraulic system to the machine support can provide lifting power that is greater than the power produced by mechanics in lifting or holding loads that exceed their capacity. Apart from that, implementing a culture of occupational health and safety is important to realize workforce welfare. What is not expected when repairing a car's clutch lining is a shift in the load support of the car's engine which can cause damage to other components and can even endanger mechanical safety. The property of magnets that can attract metal objects can be used to improve K3 in the automotive industry as an effort to prevent engine supports from shifting position when repairs are carried out on car clutch linings.
