Assessing Cause of Defect Using Failure Mode and Effect Analysis

Berty Dwi Rahmawati — 2023-05-22

A company should implement good quality management to maintain consumer confidence in producing quality products. FMEA serves to identify product failures in a process and the causes of defects or losses that occur during the production process of a product, component, or system. The research aims to analyze quality control and identify production defects that cause a decrease in quality. The samples studied were rejected goods in production activities. Forty damaged parts were used as the samples in this study. This study used both qualitative and quantitative analysis. Quantitative analysis was conducted to determine the type of rejection and then to rank the risk, while qualitative analysis was performed with Ishikawa diagram to evaluate risk priorities. This research not only helps identify and assess the root cause of rejected goods but also affects the following year's planning by proposing measures to reduce risk. Check sheets and histograms are used to present further research. The analysis results show two classifications of defects in production: size error and painting error, with the most dominant defect, size error, and equal to 73.17%. Based on the analysis of the causes of defects, several factors were found that caused product defects; man, material, method, machine. The man factor has the highest value in contributing to defect, with an RPN score of 192.

Parameter Optimization of Printcake Machine Using Full Factorial

Ahmad Amirudin Assidiq — 2023-05-22

This research analyzes pancake batter and discovers the ideal printing parameters on the HALTech Printcake machine, the machine was newly developed and hasn’t been optimize yet where the prior research on 3D Printing pancake batter never been done. This research aim to optimize the printing parameter in order to get pancake close to proposed design. 3 Level full factorial were carried out to understand the response of all the available combination of parameter. There are 2 parameters proposed on this research velocity: 50 mm/s, 60 mm/s, 70 mm/s, and micropump voltage: 3.5 volts, 4 volts, and 4.5 volts. Balance between two parameter needed in order to get the best printing result, Velocity refer to the movement speed of the axis and the micropump voltage refer to how many material will be extrude or flow rate. Design specimen of a straight line 8 cm long and 0.35 cm wide proposed. The results showed that the length error was not significantly affected either by the velocity of the axis movement or the micropump voltage, whereas for the printed area error, it was significantly affected by the velocity, and for the micropump voltage, it did not have a significant effect. Optimized combination of parameter obtain in this research was velocity of 70 mm/s, and a micropump voltage of 4 volts and overall was able to print better specimen then the average experiment in term of printed area error

Barrier Factors Model of Innovation Process in The Furniture Industry Supply Chain (Case Study at PT. Duwa Atmimuda)

Wiwik Pratiwi — 2023-05-22

PT DUWA ATMIMUDA is a company engaged in manufacturing in producing stainless metal products and furniture frames. PT DUWA ATMIMUDA is experiencing problems with the lack of application of technology in terms of marketing, seen from the absence of social media utilization, causing the company to find it difficult to expand market share. This study aims to identify the factors that hinder the company's innovation process using the Interpretive Structural Modeling (ISM) method and classify the model using MICMAC Analysis. The results showed that the ISM model of the barrier factor for the innovation process in the furniture industry supply chain has 6 levels. After the ISM model is obtained, the next process is to classify each variable indicator on the barrier factors of the innovation process with the help of MICMAC analysis. There are 4 classification clusters, the first cluster (autonomous indicators) has one indicator. While in the second cluster (dependent indicators) there is one indicator. In the third cluster (linkage indicators) there are 9 indicators. In the fourth cluster (independent indicators) there is one indicator. The third cluster (linkage indicators) is the highest cluster of indicator spreads where this indicator has high control and dependence. The output of the ISM analysis is expected to be used as a strategy for developing the innovation process in the furniture industry supply chain of PT DUWA ATMIMUDA in achieving business success.

Green Marketing and Intention To Buy Green Product: Systematic Literature Review

Sri Lestari — 2023-05-22

Society in the current period is facing various kinds of challenges and obstacles related to the acceleration of urbanization and industrialization. As for the problems at the moment, namely the health crisis and pollution that can threaten the present or future generations so that action is needed to ensure optimal living conditions, it is becoming increasingly important to understand green marketing and various other forms of support. Therefore, the aim of this research is to carry out a systematic review of the literature to identify several factors that influence green marketing. For this study, the method used was a Systematic Literature Review (SLR) which was carried out by following the procedure and followed by a meta-analysis to see the relevance of the published articles. This study uses VOSViewer as auxiliary software and uses Publish or Perish to help group data. From the search results, a total of 865 related articles were found for 2017-2022 and sorting was carried out to find relevant articles. The literature review was carried out using qualitative analysis, which resulted in four keywords; green marketing mix, attitude, purchase decision, and green marketing. In the end, we propose a framework that is developed based on some of the findings obtained. It is hoped that this framework can be used for a better understanding of green marketing factors that influence consumer purchase intentions

The Mental Workload Analysis On Female Educators During Covid-19 Pandemic Using Nasa-TLX Method

Marulan Andivas — 2023-05-22

The fate of women workers during the pandemic is quite worrying. The role of women's triple burden in these times is getting heavier. Mental workload is a multidimensional construct that demands attention, performance, and skills of workers according to their work environment. This study aims to find out the mental burden felt by female workers during the pandemic. The subjects of this study were female educators at the University of Balikpapan. 5 subjects feel a Very high mental burden on work activities during a pandemic, namely subjects 06, 14, 19, 23, and 25. There are 18 subjects who feel a high mental burden including subjects 3, 4, 5, 7, 8, 10, 12, 13, 16, 17, 18, 20, 21, 26, 28, 29, 30, and 31. Then, 3 subjects felt a moderate mental load, and 2 subjects felt a low mental load. If average, then the mental workload of female educators at the University of Balikpapan is 56,623 categorized as high. This study also seeks to investigate the correlation between the perceived workload of the subjects and several factors including age, marital status, education level, address, family size, income, COVID-19 survivor status, and family members who are COVID-19 survivors. The result showed that the number of family members is the only significant factor that influences the mental workload.

Mirga Maulana Rachmadhani — 2023-05-22

In every large, medium, and small industrial enterprise, risks must occur in the business process. The study conducted at one of the SMEs in the Bantul, Yogyakarta, namely Rajut Bamboo SME. Further, the obstacles that often occur are delays in delivery, product damage, and also other obstacles. The risk management framework has an important role in this study. Therefore, the approach used ISO 31000 method and the SCOR Model in making a proposed framework to improve risk management performance. Based on the proposed framework that has been made, the risk identification process in Rajut Bamboo SME has 32 risks in its business processes. The risk mitigation proposal is carried out on seven risks in the high-risk category. The risk mitigation results are obtained in the risk codes D3, M2, P5, and A1 down to the medium risk category, then the risk codes D9, D2, and M6 down to the low-risk category.
