Abstract

Transportation of green fillers for composites has serious densification implications due to particulate shape irregularities and size distributions. To date, few scientific studies are available on the tapped density measurements of orange peel particulate fillers. In this work, experiments were conducted on the tapped density of orange peel particulates in gentle and successive taps to the measuring cylinder containing the particulate matter. Taguchi's technique of "smaller-the-better" quality characteristics used in measuring the signal-to-noise (S/N) ratio was applied to determine the optimal setting of the tapped density process parameters. Within a range of taps from 1 to 48 points, all tapped points showed that 0.425mm OPP has a higher average apparent density of 3.22g/cm2 than 0.600mm (i.e. 3.189g/cm3) except for points at 8, 28 and 32 taps. Furthermore, for the 0.600mm OPP, its average tapped density improved by 6.97% compared to its average apparent density. Moreover, it was found that the Taguchi optimal setting for the tapped density of OPP given was A1B1C1, which reads as 8.727 number of taps, a tapped density of 4.433 and 4.395g/cm3, respectively, for the 0.425 and 0.600mm OPP samples sizes. This means that the required number of taps to obtain OPPs with light density and structural integrity to meet improved composite variety demands would be 8.727 taps, while a tapped density of 4.433 and 4.395g/cm3 is required for the 0.425 and 0.600mm OPP sizes. Hence, the number of taps was the tapped density parameter that had the greatest effect on the S/N ratios of the tapped filler materials. The results are of immense benefit to composite design engineers and equipment manufacturers for behavioural simulation and testing purposes.

Abstract

The current research consists of a machining process involving AISI steel where the input parameters are the cutting depth, feed rate and cutting speed while the responses include the cutting force, surface roughness and tool wear. Usually, heat is generated during the turning process and various machining processes, and to reduce it, coolants are considered. In this work, CuO and Al2O3 were used as nano lubricants (MQL). Data obtained from the machining process were inserted into Minitab 18 software where quadratic objective functions were formulated as related to each output concerning the input parameters. Objective functions were optimized with the aid of C++ programming code. The cuckoo search algorithm was used for the optimization process of the work. This work clearly shows a reduction of the output parameters that is, cutting force from 243N to 127.20N, surface roughness from 0.66µm to 0.368µm and tool wear from 0.069mm to 0.0046mm using CuO as the nano lubricant. While using Al2O3, cutting force was lowered from 363N to 197.63N, surface roughness from 1.98µm to 0.148µm and tool wear from 0.219mm to 0.063mm. This clearly shows that using CuO helps to obtain a better cutting force coupled with elongation of the tool life but Al2O3 best gives a better surface finish.

Abstract

The industrial sector is the backbone of the country in building the defense sector and economic stability that needs to maintain productivity and be competitive. One of the companies that manufacture automotive components, Mitsubishi, manufactures automotive components and must have zero defect requirements. However, in practice, it was found that 1 (one) unit of CJM had a brake caliper malfunction in the condition that the unit was ready to be sent to the carpool consumer of a company that produces automotive components. The damage is a discrepancy in the diameter of the piston seal, which closes the gap between the piston and the piston housing, allowing for brake fluid leakage, which affects the "zero defect" commitment. Through the application of the Root Cause Corrective Action (RCCA) method with the formation of a Root Cause Investigation (RCI) team, an investigation was carried out to find the root cause of the failure. However, the data processing results of the diameter of the seal thickness obtained have a Cp value of 0.98 and a Cpk of 0.81, which means the process has not been able to work optimally. Therefore, we decided to make some improvements, adding Standard Operating Procedures (SOP), Work Instructions (WI), and making Poka-Yokes as corrective actions in dealing with this problem. After almost 3 months since the investigation began, the data processing results on the piston seal were Cp = 1.86 and Cpk = 1.80.

Abstract

In the last six months, one of the Bank Central Asia (BCA) in Central Jakarta received various kinds of complaints from customers every month. The complaint relates to the Customer Service Officer (CSO) who is not optimal in terms of service. This is of concern to research, because competition in the service industry, especially banking, is increasing every year. This research aims to analyze improving the quality of service to customers and provide appropriate solutions for the continued trust of BCA customers. This research method uses the Quality Function Deployment (QFD) method combined with customer complaint data through questionnaires and comparison data with competitor banks through benchmarking. This research found six causes of declining CSO service quality based on Voice of Customer (VOC). Meanwhile, from the 6 causes of problems, seven corrective actions were produced using a correlation matrix and technical actions to improve the quality of CSO services. After measuring aspects using the QFD method, the resulting importance level was 17%, meaning it was important to repair, the aspect difficulty level was 2%, meaning it was easy to repair, and the estimated cost aspect was 15%, meaning the cost was low in repairs. Corrective actions on the part of the CSO have been maximized in providing services to customers at BCA Branch Unit Offices (BUO). Gajah Mada, Central Jakarta.  So that in the coming years the quality of CSO services will continue to be evaluated to reduce complaints from BCA customers.

Abstract

At present, there is a continuous escalation of labour costs, material costs and other welding-related costs and stabilizing them is challenging. Therefore, optimization of the welding process is essential to stabilize the situation. In this article, an aspect ratio-based Taguchi method is proposed to control the operational performance of the laser welding process while welding the Al-Mg-Mn-Zr-Er alloy sheets. The direct parameters considered are the laser power (LP), welding speed (WS) and welding feed rate (WFR). The aspect ratios analyzed are LP/WS, LP/WFR, WS/LP, WS/WFR, WFR/LP and WFR/WS. The aspect ratios are introduced into the factor/level framework, and the results, transmitted as orthogonal arrays are changed to signal-to-noise ratios. The final results are the delta values, ranks and optimal parametric settings. The principal results indicate that for the LPWS and LP/WFR formulation, the optimal parametric setting is LP/WS1LP/WFR3, which is interpreted as 1.6 kWmin/m LP/WS and 0.35 kWmin/m of LP/WFR. The corresponding delta values are 3.875 and 2.6288 while the positions of 1st and 2nd were obtained by LP/WS and LP/WFR aspect ratios, respectively. It was established that the LP/WS, WS/WFR and WFR/LP are the most important aspect ratios for the laser welding of Al-Mg-Mn-Zr-Er alloy sheets. Therefore, prioritization in resource distribution should be given to these parameters according to their positions. This article serves as a source of information for welding decision-making.

Abstract

PT XYZ is one of the companies engaged in the precast concrete manufacturing industry which is specially designed to meet the needs of industrial markets such as high-quality building and building construction. The machine under study is the machine used for assembling the spun pile reinforcement frame in the rotary workshop. The purpose of this study is to analyze the application of Total Productive Maintenance (TPM) through the effectiveness and efficiency of heading machine performance and analyze the factors that affect the Overall Equipment Effectiveness (OEE) value and present a proposed heading machine maintenance strategy. The method used is OEE with Six Big Losses analysis. For the analysis of the six big losses on the OEE value, namely the value of Idle and minor stoppage (a decrease due to many machine stops) which is a factor that has the largest percentage of the six big losses with a resulting factor value of 7.0%. Then followed by reduced speed losses (decrease in engine speed) of 3.96% and then deffect losses of 3.48% and the three other factor values, namely breakdown losses, setup losses, and yield losses. Measurement of the level of effectiveness and efficiency of the heading machine at PT XYZ using the OEE method for the period 2022 in January - December obtained an average value of 78.28%. The resulting value is still far from the ideal OEE standard value of 85% which refers to the world class standard. The lowest OEE factor value is obtained from the calculation of Performance Efficiency of 86.29% where it is necessary to update the machine maintenance scheduling so as to increase the efficiency of the heading machine performance that supports the production speed of the company.
