Emerging technologies had marked the emergence of the Industry 4.0 era. Despite the problems experienced with COVID-19, many experts believe that Industry 4.0 is an inevitable reality that many businesses must face in the future. One of those technologies is the Internet of Things (IoT), which may generate so-called "big data" that will be useful for business insight. However, after performing a rigorous literature review, articles related to the impact of the IoT and big data implementations for business performance in the form of a model were rarely found. Among the available literature, some elements that may be considered are: (1) business process improvement;(2) marketing strategies; (3) business management innovation; and (4) business performance. Therefore, this paper proposes an implementation model of IoT and big data to pursue business performance. Thus, a survey was conducted with managerial respondents from the manufacturing industry. For analysis purposes, a partial least squares structural equation modeling (PLS-SEM) methodology was implemented to examine the fitness of the model. The analysis was conducted in Smart PLS 3.0, and the goodness of fit (GoF) calculated for this model was 0.63, larger than the required 0.38 for a robust and accurate result. This model was implemented in a sample manufacturing company to seek improvement. Regarding this effort, several improvements were added as input by the manufacturing players to enhance the model.

Paper pulper machines a capacity of 83 litres/process must have a low-cost material, robust and safe to operate. Paper pulper machine components analysed are tubes, frames, helical screw shaft and the shaft holder. The method uses a static structural analysis to obtain von mises stress and displacement. Static structural analysis uses finite element analysis with the help of CATIA® Software. The safe component size and lowest cost (safety factor more than 2.5) were selected in this study. Calculation of costs by multiplying the size of the material needs by material prices. Tube components use SUS 304 with thickness variations of 0.5, 0.6, 0.8, 1, 1.5, and 2mm. Frame and shaft holder using L shape ASTM A36 size 40x40mm and 50 x50 mm with thickness variations of 3, 4, and 5 mm respectively. Variations in material size are determined based on standard material sizes available on the market. The simulation result of each component shows the thicker the material, the lower the von mises stress, the lower the displacement and the higher safety factor. Tubes with a thickness of 0.5mm have a von mises stress of 4.43 MPa, a displacement of 4.7 x 104 mm with SF 56.4 is safe and were chosen because of the lowest material costs (IDR 360,009). The frame size was chosen 40x40x3 mm based on the SF frame value (26) with the lowest material cost (IDR 197,800). The shaft holder is also chosen for the size of 40x40x3mm where the SF value (3834) and the lowest material cost (IDR 14,400). Helical screw shaft size is chosen at 0.5mm thickness where SF is 304 and material costs IDR 100,968. The overall results of the static structural analysis on various sizes of the paper pulper machine components showed ovon under Oyield, small displacement, and SF is safe.

This paper presents rotor power optimization of the Horizontal Axis Wind Turbine of various parameters such as airfoil, angle of attack, and wind speed. Simulation of HAWT rotor power uses Blade Element Momentum (BEM). Furthermore, optimization using the Taguchi method with L16(43) orthogonal array. The parameters used in this study were: airfoil NACA (National Advisory Committee for Aeronautics) 4412, NACA 2412, NACA 4412-NACA 2412, NACA 4412mod-NACA 2412mod; angle of attack 3˚, 4˚, 5˚, 6˚; and wind speed of 5, 6, 7, 8 (m/s). The simulation uses the general parameter at 1 MW HAWT. Several types of NACA airfoil, angle of attack, and wind speed were simulated, then optimized to obtain optimal parameters for the HAWT output power. The results of this study found the most optimal rotor power, namely the condition of the NACA 4412mod-NACA 2412mod airfoil, 3˚ angle of attack, and 8m/s wind speed. Wind speed is the most significant influence factor based on ANOVA analysis ranked 1st based on S/N ratio analysis, 2nd rank is an airfoil, and 3rd rank is the angle of attack. The higher the wind speed, the greater the rotor power generated.

In Indonesia, not all of them get full electricity, in many regions there are not enough sources of electrical energy, but in Indonesia there are quite a lot of child air currents such as halal rivers because the benefits are as a source of electrical energy, PLTMH is very good to be used in hilly areas with manufacturing costs that are not quite expensive and not so difficult in its workmanship. This PLTMH uses a 2inch pipe size and a waterfall fall that is ideally used 0.2 m and turbine diameter 0.4 radius 0.2 specifier 18 Volt 15 Ampere generator uses 32 ampere / hour battery for storage of power generated by PLTMH and the inverter converts the dc current to ac power generated by PLMH. With the turbine rotation that is obtained by PLTMH 80 Rpm and produces 10.705 Watt turbine output power with generator output power and 7.996 Watt PLTMH output power

This paper presents a static structural analysis of the Sports Utility Vehicles (SUV) Patriot chassis uses a type of ladder frame with 440 G JIS STAM carbon steel tube and bracket material is AISI 1020. Static load on the patriot chassis is varied in a normal load and an extreme load. The element method simulation is carried out on the chassis until the horizontal chassis position is 0˚, 30˚ downhill and 30˚ uphill. Static structural analysis on the patriot chassis frame using the finite element method found that the overall design is safe under various load variations and support variations. Applied normal load with a total of 4 supports (4 wheels) on the patriot chassis design which is varied by its tilt, show that the 0˚ chassis position produces the highest von mises stress (86.1 MPa) and the highest displacement (0.38mm). The results of extreme loading on various supports of the 3 wheels alternately patriot chassis design show that the highest von mises stress (264 MPa) and the highest displacement (5.11 mm) occurs at 0˚ chassis position with rear right not support. The factor of safety from various variations in loaded, tilt position, and the number of supports of the Patriot chassis design is more than 1 so that the chassis design is declared safe.

Transportation is important for humans. Generally, the means of transportation use machines that can pollute the environment. The use of fuel oil which is used as a driving force for vehicles can be the main cause of the release of various pollutants. Emissions generated by internal combustion engines can cause many losses. Losses due to emissions include losses on health, the environment, and economic impacts. Besides, the amount of fuel oil resources is decreasing every year. For that to anticipate this need development electric bike. The campus environment, especially that of the more established universities, has entered the public consciousness as being a haven for electric bike use. The main advantages of electric bikes are economical and environmentally friendly. The objectives of this study were (1) to design an electric bike, (2) to analyze the strength of the sliding frame of an electric bike, (3) to test the distance traveled by an electric bike.
