Lean Concept Implementation: Waste Reduction on Road Transport in Apparel Industry
1-18Views:29Logistics costs have become a concern for the Indonesian government, and in 2024, they accounted for 14% of the Gross Domestic Product (GDP). Transportation costs are one of the elements of logistics costs. This condition has compelled leaders and teams in the apparel industry to allocate resources efficiently, effectively, and productively, with minimal waste. Based on this reason, the organization sought to identify the root causes of waste and implement improvements in transportation. These wastes of road transportation were identified and reduced by DMAIC (Define, Measure, Analyze, Improve, Control) method and lean tools, including Value Stream Map (VSM), Lean Metrics, Five Whys (5Ws), Transportation Overall Vehicle Effectiveness (TOVE) – Overall Equipment Effectiveness (OEE), transport software, and SmartSheet. Data collection and observations were conducted in 2024 and 2025, resulting in improvements across various aspects, including a 75.75% reduction in parking time, a 4.67% decrease in distance traveled, an 82.66% decrease in vehicle utilization, and a 16.66% reduction in transportation costs. The Lean concept remains an effective tool for reducing waste.

Creativity and Innovation to Improve Processes in a Textile Industry
80-96Views:330In this scientific work, the My Creative Idea (MIC) program was created and developed in the Coteminas S.A. textile industry, distributed among the organization's units in the country with emphasis on the São Gonçalo do Amarante unit in the state of Rio Grande do Norte. The aim was to critically analyze the improvements of industrial-scale processes resulting from the creativity and innovation intrinsically incorporated and experienced daily in the program. Thus, the general objective of the work was to evaluate the improvements in the productive processes coming from an innovation program in a textile industry, considering as specific propositions with respect to calculating the gains with reduction of losses, cost of implementation of ideas and measure financial returns and evaluate employee satisfaction according to the program. Moreover, there was free access in the company to be able to collect valuable information that could formalize a robust database for later structuring of the document, as well as the application of action research in the form of questionnaires. Therefore, the results verified clarified and emphasized the program's aggregating character to the organization in a general way under aspects that approach the financial spheres, the quality, and the satisfaction and motivation of the employees involved in this whole scenario. I suggest continuing to work on a continuous improvement methodology to further enhance My Creative Idea over the years, as well as insert this method of work to units that have not incorporated this program into their business strategies.

Study of Rotating and Jet Plasma Treatments on Surface Wettability of Glass
67-79Views:127This work investigates the wettability properties of a glass surfaces by using atmospheric pressure cold plasma systems. Treatments were performed by using a rotating-head unit and a jet-type torch during the plazma treatments. The nozzle-to-surface distance (8–15 mm) and the feed rate (50–400 mm/s) were modifying. The untreated glass showed limited wetting, with average water and ethylene glycol contact angles (WCA and EGCA) of 64.7° ± 1.8° and 45.2° ± 1.5°, respectively. After plasma treatment, both systems showed clear improvements, although their efficiency profiles were different. Using the rotating plasma head at 8 mm and 100 mm/s speeds, the WCA decreased to 9.3° ± 0.8°, indicating almost complete wetting. Jet plasma achieved similar results (WCA = 14.1° ± 1.2°), but slightly less uniformly. Changes in wettability were closely related to the exposure time determined by the feed rate: slower movement increased activation, while overexposure occasionally resulted in small thermally induced surface marks that were visible under an optical microscope. As the results showed the rotating plasma reached more homogeneous activation, while the jet system provided stronger local effects at a lower energy input. Based on these results the atmospheric plasma is effective in increasing the surface energy. Rotating systems appear to be advantageous for large, flat areas, while jet plasma is better suited for localized surface modification aimed at improving adhesion or coating performance.

Food Industry 4.0 Readiness in Hungary
1-12Views:484In terms of production value, the food industry is the third-largest in Hungary, the first in Hungary in terms of the number of employees, and the first in Europe in the processing industry, as well as a significant user of resources. The research examined the state of art of digitalization readiness, focusing on I4.0 technologies, which supports the management to operate more efficiently the enterprise and to make better decisions. So the focus was on integrated enterprise information systems, management support systems, business intelligence systems, industry 4.0 technologies, and issues related to their application. The analysis based on an online questionnaire survey the request sent to 4.600 enterprises, the response rate was 5% which was representative of the branches of production, covered the Hungarian food and beverage manufacturing sectors in 2019. The companies were asked the most critical technologies in development, going towards Industry 4.0. The research tools were LimeSurvey, Mailing List Server, Excel, Power BI (Desktop, Publishing Server to distribute the results). The used analysing methods were making calculations, pivot tables, models, dasboards. We found that a significant portion of businesses, 78 %, use mobile devices in the manufacturing process. The three most relevant digital technologies are geolocating (GPS, GNSS), cloud computing, and sensor technology. The current level of digitalization and integration cannot be said to be high, but respondents are very optimistic about expectations. Improvements are expected in all areas in the next 2-3 years in terms of digitalisation and integration. Vertical integration involves, first and foremost, cooperation with partners in the supply chain. Horizontal integration means close, real-time connectivity and collaboration within the company. Unfortunately, between 6% and 15% of SMEs (approximately 9% on average) and large enterprises, 36% have a digital strategy. According to the survey, the sector needs significant improvement and creating a digitalization strategy.

Analysis of the Policy Background of Transport Related Use of Renewable Energy
124-129Views:239The EU energy policy prioritizes the following principles: sustainability, competitiveness and security of supply and addresses the reduction of greenhouse gas emissions as a priority. The related EU policy (including the White Paper on Transport) outlines these principles, identifies goals and opportunities for action. At company level methodological guidelines and standard procedures can be used to assess the carbon footprint of the organization, to generate efficiency goals and to prepare action plans. In the Hungarian policy framework, a comprehensive National Sustainable Development Framework Strategy defines the basic principles for the analysis of the sectorspecific or regional strategies. Sustainable Energy Action and Climate Plans (SECAPs) integrate energy and climate issues and include interventions and improvements for the better use of renewable energy sources in transport at municipal level. As a summary it can be stated that exploration of the policy background would needed to influence the use of renewable energy sources for transport and definition of the development goals can help economic organizations to transform their mobility patterns and reduce related carbon footprint.

Sustainability Goals - Can we Reduce Malnutrition?
268-276Views:435Nowadays, some parts of the world hunger still exists. One of the milestones of the Millennium Development Goals (MDGs) is eradicating hunger. These goals include a road map for progress and documenting specific steps to combat hunger. Another type of hunger that has been very common in these days is hidden hunger. Eradicating extreme poverty and hunger is still an illusion. The number of people living in extreme poverty and malnutrition has fallen slightly in recent years. Measuring hunger is a very complex issue. The Global Hunger Index is a tool to comprehensively measure and monitor hunger at global, regional and national levels. Despite noticeable improvements, the question remains: will the world achieve its Sustainable Development Goals (SDGs), including the eradication of hunger, by 2030? Despite these efforts, even in economically developed countries, hunger or food insecurity still exist.

A Domestic Investigation of Online Banking
22-32Views:523Nowadays, the spread of digitalization is constantly increasing. The current rising generation is already a “digital native”. As part of digitalisation, mention should be made of the Internet, which has been given a prominent role in our daily lives. We search for information on the Internet, we communicate, we buy. Due to these factors and the pandemic in 2020, internet administration has become a priority. Banks need to constantly adapt to meet their needs, promoting convenient, home banking. In the course of our research, we focused on this continuous adaptation and the resulting improvements. The research focused on the Internet and mobile banks of large Hungarian banks. Sampling took place over 2 periods. Among the primary research tools, we chose document analysis, and netnography. In the research, we compared the functions available on the platforms, the consumer perception of mobile banks and other variables. Based on the results obtained during the research, it can be stated that domestic banks are constantly developing their application along different trends and trying to adapt to changing needs. Serious changes had to be made in the mobile banks of most large banks, even with the permanent elimination of their former mobile banks. Changes can have a strong impact on consumers, who are often more likely to have a negative view of them. Digitalisation is also particularly important in this sector. The study contains the details of the course work prepared for the Scientific Students’ Associations Conference.
