Abstract

The lifting process is needed, among other things, to move goods and maintain the position of the equipment. In this lifting process, spreader bars are needed because the size of the equipment being lifted is too large, but the sling must not hit the equipment. This spreader bar will work with high intensity due to repeated or cyclical load treatment, so fatigue in the structure is likely to occur. Thus, it is necessary to analyze the strength of the structure and estimate the life of the spreader bar. The design method used is the Ulrich method, which involves creating three design concepts from which the best design will be selected according to the selection criteria. Modeling is done with Fusion 360 software, and strength and fatigue life analysis is done using ANSYS Workbench 2023 R1 software with the aim of knowing the amount of stress from the loading received by the structure. The strength analysis of the spreader bar structure in the selected design concept obtained a maximum stress value of 154.71 MPa; this value is still at a safe limit because it is below the maximum allowable stress value of 166.667 MPa, and the safety factor obtained is 5.6026. This value is safe because it is greater than 1. The total estimated material cost required for this spreader bar is IDR 21,866,910.67.

Abstract

The dimensional accuracy of the workpiece might be impacted by geometric variations that machines frequently experience. The geometric shape of the workpiece as a result of the machining process can be used to quantify machine quality and can take the form of cylindricality, smoothness, roundness, and other geometric shapes. The results of the workpiece surface's cylindricality will depend on machining parameters such engine rotation, feed speed, and feed depth. For the design of the research experiment and the data analysis, this study employs the Box Behnken Design in Response Surface Method that is figuring out the trial variation using 3 stages. The specimen used was ST 42 steel, and a DNMG 150404 carbide insert tool was used on a Pinacho L-1/260 conventional lathe to perform a total of 15 experimental modifications on the specimen. Furthermore, the cylindricity test was carried out using a dial indicator. The research results on the effect of parameters on surface cylindricity, namely engine speed with a Pvalue of 0.068, depth of feed with a Pvalue of 0.784, and feed speed with aPvalue of 0.839, the three parameters were declared not to have a significant effect. The engine rotation parameter provides a contribution effect of 26.87%, the depth of feed is 0.52% and the feed speed is 0.28%.

Abstract

A large material removal rate and minimal surface rigidity are the desired objectives of this study with the right process parameters to obtain a large material response rate and a minimum surface hardness. The parameters used are spindle speed, feed rate and depth of cut. The experimental design is based on the response surface methodology of a box behnken design. The trials were randomized in three replications to produce a more optimal result. The results of the research showed that the influence of the parameter on the material removal rate is spindle speed with 0.442, feed rate with 0,000 and depth of cut with 0,000. parameter feed rate and deep of cut are stated to be significantly influenced. On the other hand, the influence of the parameter on the surface rigidity is that spindle speed with a of 0.017, feed rate with a of 0,000 and depth of cut has a of 0.074. Furthermore, the combination of the most optimal parameters for the material response variable removal rate and surface rigidity is the spindle speed of 2006 RPM, the feed rate of 252 mm/min and the depth of cut of 0.1965 mm.

Abstract

CNC TruLaser Tube 5000 TRUMPF machine is used to perform cutting process in PT. Dempo Laser Metalindo. The quality of the cut product produced is required to have minimum roughness value, but in every cut result especially on Square Pipe St 37 material there is cutting defect. Cutting defect in the product result is surface roughness. Surface roughness can affect the cutting rate on the material, the solution to get cutting quality with minimal roughness and maximum cutting rate is to analyze the parameters that affect the response by optimizing the parameters. The parameter variables to be optimized are focus point, cutting gas pressure, nozzle distance, and laser power. This study uses Square Pipe St 37 material and the experimental design uses Taguchi Method combined with Grey Relational Analysis using orthogonal matrix L9 (34). From the results of the research that has been conducted, it was obtained that the most optimal combination of parameters for cutting rate and surface roughness is the focal point at level 2 which is 2 mm, nozzle distance at level 3 which is 1,1 mm, and laser power at level 3 which is 2700 W. The focal point parameter provides a percentage contribution of 38.60%, while the nozzle distance parameter provides a percentage contribution of 6.42%, and the laser power parameter provides a percentage contribution of 35.92%.

Abstract

This paper proposes an improved Maximum Power Point Tracking (MPPT) algorithm for photovoltaic (PV) systems under partial shading conditions. The proposed method enhances the widely used Incremental Conductance (IC) algorithm by incorporating an incremental fuzzy control technique. The conventional IC algorithm suffers from limitations in adapting to rapidly changing irradiation conditions due to its fixed step size. The proposed Inc-Fuzzy algorithm dynamically adjusts the step size based on the change in power and voltage, enabling it to better track the Global Maximum Power Point (GMPP) under partial shading. Simulation results demonstrate that the Inc-Fuzzy algorithm achieves an average accuracy of 98.29% under constant irradiation and outperforms the conventional IC algorithm by 1.69% in terms of captured power during sudden irradiation changes. This improvement highlights the effectiveness of the Inc-Fuzzy approach in enhancing the performance of MPPT for PV systems under challenging operating conditions.

Abstract

Submerged Arc Welding(SAW),the molten weld metal is immersed in aflux that protects it from air contamination, forming welding slag which is strong enough to protect the weld metal until it solidifies. The used electrode was AWSA5.17EL12. The base metal being welded is ASTM A283 Grade A. In this study, the effect of angle distortion on the T joint was observed by changing the welding parameters. In order to obtain the optimal results, an attempt was made to link the welding parameters to the angle distortion through a mathematical model by using the Box Behnken statistic technique, the feasibility of which was then tested by using ANOVA analysis. What was obtained was analyzed with the help of the response surface methodology (RSM = Response Surface Methodology) then

This research explores innovative business models for the commercialization of Remotely Operated Vehicles (ROVs) in the Indonesian market. Through case study analysis and interviews with industry experts, this research identifies and evaluates the potential of business models such as ROV-as-a-Service, technology licensing, and joint ventures. The research results show that the ROV-as-a-Service model has the most promising potential, with higher adoption rates among MSMEs due to the flexibility and cost efficiency it offers. In addition, this research also found that the integration of digital technology such as IoT and data analysis can increase ROV operational efficiency and provide added value for customers. These findings provide important implications for companies wishing to enter the ROV market in Indonesia, as well as for policy makers in supporting the development of the marine industry. The ideal number of case studies and interviews in a research depends on several factors, including: Depth of analysis: The deeper you want to dig into a phenomenon, the more cases need to be researched. Case variety: If you want to see a variety of business models or challenges faced by different ROV companies, you need to choose a variety of cases. Availability of resources: Time, cost, and accessibility to data will limit the number of case studies and interviews that can be conducted.
