Published: November 2022

Прогнозирование напряженно-деформированного состояния трубопровода в зоне сварных соединений имеет важнейшее значение для решения задач по обеспечению его надежной и безопасной эксплуатации. С целью создания систем прогнозирования качества сварных соединений и оптимизации управления сварочным производством в настоящее время широко используется компьютерное моделирование сварочных процессов. При этом по причине существенной сложности указанных процессов их описание математическими зависимостями крайне затруднительно, и распространенной практикой является применение упрощенных моделей, что часто приводит к значительным расхождениям результатов расчетов с экспериментальными данными, полученными на реальных трубопроводах. Авторами поставлена цель по созданию простой и точной модели распределения тепловых полей и напряжений в сварном соединении, которая может быть применена для каждой марки стали и любой геометрии сварного шва. Для моделирования использовался программный продукт ANSYS Workbench. По результатам был разработан подход, позволяющий создавать достаточно точные цифровые модели распределения тепловых полей и напряжений в зоне сварного соединения без проведения моделирования микроструктурных преобразований, возникающих вследствие фазовых переходов. Верификация цифровой модели показала ее хорошую сходимость с экспериментальными данными - расхождение значений составило не более 2 %.
Predicting the stress-strain state of the pipeline in the area of welded joints is of crucial importance for solving the tasks of ensuring its reliable and safe operation. In order to create systems for predicting the quality of welded joints and optimizing the management of welding production, computer modeling of welding processes is currently widely used. At the same time, due to the significant complexity of these processes, their description by mathematical dependencies is extremely difficult, and it is common practice to use simplified models, which, in turn, often leads to significant discrepancies in the calculation results with experimental data obtained on real pipelines. The authors of this article set a goal to create a simple and accurate model of the distribution of thermal fields and stresses in a welded joint, which can be applied to each steel grade and any geometry of the weld. The software product ANSYS Workbench was used for modeling. Based on the results, an approach was developed that allows creating sufficiently accurate digital models of the distribution of thermal fields and stresses in the weld zone without modeling microstructural transformations resulting from phase transitions. Verification of the digital model showed its good convergence with experimental data - the discrepancy in values was no more than 2 %.

Published: November 2022

In the era of the rapid development of information technology, knowledge and creativity play a key role in development. The creative industry, a very high-growth sector in Indonesia, has shown success in providing employment and economic growth. The innovation system, the heart of the creative industry, is increasingly complex because it implies a trend-shifting perspective from a supply economy to a consumer demand-driven economy. Communication systems play an important role in the social process of development. Communication not only conveys the idea of sustainable development but also creates opportunities where sustainability values can be realized. The communication system for the development of the creative industry in Jepara Regency, especially related to the woodcarving industry is currently in a crisis, very weak, and not adaptive to the environmental situation that surrounds it. The purpose of this study is to explore how strong and adaptive development communication responds to the complexity of the creative industry ecosystem in Jepara as a carving city, through the approach of Pentahelix stakeholder theory and Luhmann's social system theory. The method applied in this study is exploratory qualitative. It focuses on a theoretical approach that can explain the shifting economic perspective on the system of innovation, production and reproduction of knowledge through the Stakeholder Pentahelix model and the theory of communication systems. As a carving center in Indonesia, Jepara is an interesting case study to analyze from this theoretical approach. The results of this study have shown that Jepara's development communication system is not strong and adaptive in capturing what its people need. The development system in dealing with the complexity of the creative industry environment is still not optimal. The system is not effective in reducing and selecting feedback from the community. So, the production and reproduction of information do not solve the complexity of the environment. In addition, The convergence of theories shows the overlapping relationships between all Pentahelix Stakeholders, the interpenetration of systems, and the designation of prominent media, through science journalism, as an interpretive framework of the convergence of the theory described. For further research, it is hoped that we will further explore the complexity of the environment through the Participatory Action Research method so that the results are more representative of the construction of reality that exists in society.

Published: November 2022

Parking Management is the continual process of selecting and implementing parking policies to make the strategies take effect. The paradigm regarding parking management needs to be reviewed further from several aspects, such as planning, evaluation, and strategies including the relationships and interactions between users – communities, and the environment, as well as aspects of management, including the sustainability of parking management in the future. Through a systematic literature review of Scopus indexed articles, this study could identify concepts and theories that can formulate a new paradigm of parking management. From the sustainability theme, exploring parking management should be carried out with a special research approach taking into account the different characteristics or behaviours of drivers, as well as destination profiles and the affected communities.

The morphological structure of turfs and the activity of the main enzymes of antioxidant protection: peroxidase, superoxide dismutase (SOD) and catalase of the dominant species of mosses Barbula unguiculata Hedw,, Bryum caespiticium Hedw., Bryum argenteum Hedw. and Brachythecium salebrosum (Hoffm. eх F.Weber & D. Mohr) Schimp. from different transects of the northern exposure of sulfur mining dump No. 1 in the summer and autumn seasons were studied. It is shown that the morphological structure of the turfs of the mosses Bryum argenteum and Brachythecium salebrosum in the post-technological areas of sulfur mining is important for moisture conservation and depends on the microclimatic conditions of local growth and the life form of the species. It was found that the activity of enzymes depends on the species characteristics of mosses. The dependence of the activity of antioxidant enzymes in the investigated mosses on the intensity of light and temperature on the transects of dump No. 1 was defined. In the summer period, the highest indicators of the activity of antioxidant enzymes were noted in moss samples from the northern top of the dump, where the influence of high temperatures and light intensity, as well as lack of moisture, are particularly noticeable. Under the experimental conditions, in Barbula unguiculata and Bryum caespiticium from the northern top of the dump, under the influence of 24-hour exposure to a temperature of 42 °C, the most significant increase in peroxidase activity by 1.2–1.4 and SOD by 1.6–1.9 times was found. Increasing in peroxidase activity and SOD caused by hyperthermia were reversed by pretreatment with the protein biosynthesis inhibitor cyclohexamide, that may indicate about involvement of the protein synthesizing system in this process. It is likely that the increasing of the activity of antioxidant enzymes is caused primarily by the change in gene expression of stress proteins that control the synthesis of specific adaptogens and protectors, indicating that the extreme conditions of an anthropogenically transformed environment contribute to the development of forms of organisms with the highest potential opportunities.

Abstract: Petungsewu Village is administratively located in Dau District, Malang Regency with a population of 3,336 people. In addition to having good natural resource potential, the village also has promising tourism potential. However, the information has not been distributed properly and widely among public. Therefore, they need information system to distribute information about the village potential. The community service team from Ma Chung University carried out activities to design and create a mobile-based information system for villages with profile content and data on the potential of natural resources and tourism. The methods used are: performance data analysis and collection activities for the system and assistance in the form of installation to training after the end of system work. The results obtained from this activity are in accordance with the objectives, namely the existence of a mobile-based information system for villages, but on the other hand the mentoring process is constrained by the PPKM, so that online implementation is still not optimal and must be continued in the next period offline. But overall this activity has been able to achieve the goals expected by the implementing team and partners.Abstrak: Desa Petungsewu secara administratif terletak di wilayah Kecamatan Dau Kabupaten Malang dengan jumlah penduduk 3.336 jiwa.
