Abstract

In Indonesia, many manufacturing industry companies large and small are trying to make products of good quality to the market. This is because only companies that have good product quality can compete and survive. PT. Fajar Makassar Grafika is a subsidiary of Fajar Group that specifically handles newspaper printing production, in carrying out the process of newspaper production there are still many problems with product defects that are not by the standards of the company.The method used in this study is the Six sigma method using DMAIC stages (define, measure, analyze, improve and control). Six Sigma is one of the tools commonly used in product quality control. This method has the concept of setting quality standards until it reaches 3.4 rejects per one million possibilities.Based on the results of analysis with the Six Sigma method it has been known that in the production process there are 5 types of defects, namely blurred mold defects, dirty prints, not registers, folded and torn newspapers with sigma levels obtained at 3.92 with an average damage rate of 7760 for one million productions (DPMO). From the analysis of fishbone diagrams can be known the causal factors of defective products derived from machine, material and human factors. The proposed improvement is done using Failure Mode and Effect Analysis (FMEA) analysis, so that the company can take precautions and improvements to reduce defective products and improve product quality

Abstract

This study aims to analyze factors influencing the usage of MyTelkomsel application based on Technology Acceptance Model (TAM) theory. Data are collected using offline questionnaires distributed to MyTelkomsel application users in Makassar region and its surrounding areas. Data analysis is performed using multiple linear regression after conducting tests for validity, reliability, and classical assumptions. The results of the F-test indicate that overall, all variables collectively influence the usage variable. The results of the partial t-test show that trust, habit, perceived usefulness, and attitude are proven to be influential factors in the usage of MyTelkomsel application, while perceived ease of use and subjective norm do not have a significant impact. This study obtains an adjusted R-Square of 0.577, indicating that the examined factors can explain approximately 57.7% of the variation in the usage of MyTelkomsel application.

Abstract

This study aims to examine the green practices that have been implemented in an eco-hotel and further design services to meet the customer expectation. The data was collected through a survey distributed via e-form to 250 hotel guests who personally experienced green services at the hotel. Through the integration of Green SERVQUAL (GSQual) and the KANO model, there are 11 attributes that need to be improved. Further, the improvement of green services is prioritized using the technical importance score from the QFD. The highest rating of technical importance is 376.62, indicating the need to install an automatic faucet sensor to reduce water consumption waste. By implementing the improvements, the hotel will be able to better manage its water consumption and thus satisfy their customers.
