Abstract

Drilling process is one of the most common machning process in industrial sector. More than half of the metal-cutting processes are conducted by the drilling process. Drill bit has influenced the results of the drilling process. Therefore, selection of the suitable drill bit becomes a critical factor in the drilling process. This is because the use of the suitable drill bit could fulfill the determined specification value of the hole. Six Sigma and Failure Mode Effect Analysis (FMEA) methods are used to identify factors that have influenced the results of the drilling process. Then by using the Design of Experiment, selection of the best drill bit could be done. In this study, 2 factors that influenced the result are the drill bit type and the drill point angle. Significance test using nested design through MINITAB 14 application has shown that both factors have significant influence over the hole diameter size.. Then by using the plot from the MINITAB 14 application, HPMT 1 became the best drill bit because it could fulfill the specification value. As for the best point angle in this study is 139.72º. Process capability calculation of HPMT 1 has shown that the process is in control. The conclusion is that drill bit HPMT 1 with point angle 139.72º became the best option in this study.

Abstract

The investment in information system brings significant impacts on the banking industry because it plays a pivotal role in providing better services and competitive edges. This study evaluated satisfaction level and benefit of the usage of the banking system which is m-Banking using the IS Success Model approach developed by DeLone and McLane in 2003. The population in this study was customers of one of the largest banks in Indonesia, namely Bank Central Asia (BCA) with a sample size of 200 customers. The data were analyzed using Structural Equation Model (SEM) with AMOS. The results showed that the IS Success Model consisting of system quality, information quality and service quality has a significant impact on customer satisfaction in using BCA m-Banking. This study also validates the research conducted by DeLone and McLean (2003) in developing the IS Success Model as a measure of the quality and key to the success of an information system.

Abstract

This study aims to determine and analyze the influence of work discipline, leadership, and job satisfaction on organizational commitment and teacher performance at the Bangko District Junior High School. The number of samples in this study was the entire population of the study as many as 48 PNS teachers at the Bangko District State Junior High School. Data analysis using Structural Equation Modeling (SEM) using SmartPLS 3.0 application. The results of this study indicate that work discipline has no significant effect on organizational commitment, leadership has a significant positive effect on organizational commitment, job satisfaction has no significant effect on organizational commitment, work discipline has a significant positive effect on teacher performance, leadership has no significant effect on teacher performance, job satisfaction does not have a significant effect on teacher performance, and organizational commitment has no significant effect on teacher performance.
