Authors: Wu Xi
Published: April 2021

In recent years, with the rapid development of network technology and information technology, artificial intelligence has become the development trend of modern technology. Over the past 50 years, scientists from various countries around the world have continuously explored artificial intelligence technology. Up to now, artificial intelligence has achieved great results. Compared with traditional modern technology, artificial intelligence has broken through the shackles of traditional technology, and has been highly sought after in various fields for its advantages such as being more convenient, more effective, saving time, labor and cost. Modern vocational education is an effective part of China’s higher education, mainly providing professional technical talents for the society. At present, vocational education has not been developing in China for a long time, and the application of computer technology in vocational education is even later. In recent years, although the rapid development of computer technology in China has promoted the development of vocational education to a certain extent, the actual application of computer technology in modern vocational education has lagged far behind the development of computer science itself. While many disciplines of artificial intelligence based on “knowledge engineering” have achieved certain results, modern vocational education still evolves traditional computer technology. Obviously, modern vocational education is far from artificial intelligence technology in computer application. How to effectively apply artificial intelligence technology to the summary of modern vocational education, make full use of the potential of computer technology itself, and bring new development opportunities for the development of modern vocational education has become an important issue that modern vocational education workers need to solve urgently. From the perspective of artificial intelligence technology, this paper deeply analyzes the current status and problems of the application of artificial intelligence technology in modern vocational education in China. And on this basis, this paper puts forward the feasibility suggestions for introducing artificial intelligence into modern vocational education technology. The main purpose of the research in this article is to urge our modern vocational education colleges to pay enough attention to artificial intelligence technology and to stimulate the interest of modern vocational education scholars on artificial intelligence. Furthermore, the artificial intelligence technology can be fully and efficiently implemented into modern vocational education, and more high-quality professional and technical personnel can be cultivated for the society.

Published: April 2021

In recent years, prefabricated buildings have made good development. Compared with ordinary reinforced concrete construction projects, prefabricated buildings have higher requirements for seismic resistance. In this paper, the seismic performance of the assembled building structure in smart city is studied. In the study, we use open sees to establish the finite element model, and take the common seismic performance indexes as the evaluation indexes, and compare the prefabricated structure with the cast-in-place structure from the aspects of ductility, stiffness degradation and energy dissipation. The results show that when the displacement reaches 80 mm, the energy consumption of the two structures reaches the maximum value, and the energy consumption of prefabricated structure is 20000 KN / mm, and that of cast-in-place structure is 30000 KN / mm. In addition, the research results show that the ductility coefficient of prefabricated structure is slightly smaller than that of cast-in-place structure, but its stiffness degradation is better than that of cast-in-place structure. Generally speaking, the seismic performance of prefabricated building structure is better than that of cast-in-place structure. The research results of this paper will provide certain reference value for the development and construction of smart city.

Published: April 2021

An experimental study was carried out to investigate the effect of tensile reinforcement ratio on the flexural capacity of reinforced concrete beams strengthened with Carbon Fiber Reinforced Polymer (CFRP) plates. This study aims to observe the effect of reinforcement ratio on debonding failure load of reinforced concrete beams externally strengthened with CFRP plates. Six reinforced concrete beams consisting of three control beams and three beams strengthened with CFRP plates were tested. The beams were simply supported and loaded with four-point bending. The test variable was tensile reinforcement ratio (1%, 1.5%, and 2.5%). CFRP plates were glued on the bottom of the beams with the purpose to increase the flexural strength of the beams. Analytical prediction using fiber element method was also carried out to obtain a full flexural response of the beams due to bending load. The test results show that beams with CFRP plates have higher flexural capacity for about 10% to 50% than the control beams. However, at a specified load level, two of beams with CFRP plates suddenly collapse due to delamination of CFRP plates. In addition, analytical calculation predicts well the test results in excellent accuracy.

P3-TGAI is part of the PKT Program in Padang City and Padang Pariaman District, during the covid pandemic 19, including the covid protocol 19, which was carried out during the project work. This research uses a literature review method to describe the P3-TGAI and PKT program. Descriptive statistics are used to identify the benefits of the programs for the community and the covid 19 protocol performed during project work. The results of the study were that, although the covid 19 protocol was not fully implemented, the program is useful in recovering the community income during the covid 19 pandemics.

Cold-formed steel has been used widely on buildings, especially for the roof truss-structures. This material and its typical section are beneficial in weight and strength. Despite the minimum total weight, the structure can fulfil the strength requirement. For the truss installations, screws are commonly used to join the truss members due to time consideration and convenience process. However, there is a potential failure using the screw because it does not have a nut to prevent it from detaching. In this research, experimental tests of the screw connection of the cold-formed steel were conducted. The specimens consist of two groups: 8 specimens using screws were applied in the same direction and the other 8 specimens in the opposite direction. A different application of screws was aimed to observe the effect of the screw’s head, which may play a role as a nut to prevent detaching. Typical conditions of tilted screw and indented hole on the joined channel section were found during the test. The experimental results showed that the ultimate load for two different directions of screw were slightly different within the range of 0.4 – 10.0 %. The effect of the screw’s head position was minor to the resistance of the connection.

Increase in population and urbanisation alongside demands from agricultural sector towards meeting fresh produce needs of the growing population has put severe pressure on the available natural water sources all over the world. Thus, water is undoubtedly the most contemporary crucial resources in the world. Aquatic weed plants are generally seen as a global threat to humans and aquatic ecosystem as they cannot be wholly eliminated easily. Still, various researchers and investigations have shown that they are instrumental in the field of wastewater phytoremediation, either in constructed wetlands, open ponds or hydroponic systems in an eco-friendly and economical manner with little or no sludge waste. In view of the increasing search for an alternative source of a sustainable method for wastewater reclamation, this study presents a concise review of relevant literatures on the roles of constructed wetlands and hydroponic systems in phytoremediation of wastewater. Also in the course of this study, the authors discovered that constructed wetlands and hydroponic systems have proven to be productive in remediating an array of water quality problems, with merits over the regular wetlands and conventional methods. Nonetheless, these methods are endowed with drawbacks such as inconsistency in the absorption of contaminants, large area space requirement, over dependency on environmental conditions and energy requirement. However, we suggest the use of engineered hybrid to improve its efficiency in wastewater treatment and bioenergy generation. In the case of hydroponic systems, an alternative sustainable solar energy or devices can be used to power the systems to obtain effective results at a low cost. Additionally, further studies can be employed in the use of phytoremediation technique for synchronous remediation of wastewater and production of biomass on industrial scale.

Resilience is more capable of dealing with hydro-meteorological disasters compared to the risk. Resilience is a positive concept that puts forward adaptation efforts so that more in line with sustainable development goals. This study aims to introduce the resilience concept in dealing with hydro-meteorological disasters and apply it at the provincial level in Indonesia. The methods used are: 1) measuring the climate risk index (CRI), 2) measuring the adaptation capacity index (ACI), and 3) classifying the provinces based on CRI and ACI. Grouping CRI and ACI are used to define provinces which have the potential to bounce back better (low CRI - high ACI), bounce back (high CRI – high ACI), recover but worse than before (low CRI -low ACI), and collapse (high CRI – low ACI). The study results indicate that throughout 2017 there are 10 provinces that South Sumatra, Central Java, and West Nusa Tenggara. In contrast, 3 provinces with the most have the potential to bounce back better, 7 provinces bounce back, 7 provinces recover but worse than before, and 10 provinces collapse. In general, 3 provinces with the lowest resilience are resilient levels are Riau, Bangka Belitung, and Riau Islands.

The implementation of the Contract Quality Plan (RMK) is an important thing because from the RMK we can guarantee the quality of work to meet standards so as to meet consumer needs. RMK must be made by the goods / services provider for any work to be carried out in the field. This research was conducted in the Batang Kuranji Sediment Control Building Project which was carried out by the contractor PT. PP (persero) tbk .. This study aims to determine the constraints factors in implementing the RMK. The constraints are limited to only material constraints. The data taken is secondary data, namely data from the RMK from the contractor PT. PP (persero) tbk while the primary data was taken by questionnaire to workers and interviews with employees. The method used is descriptive quantitative then descriptive statistical analysis and t test are carried out to obtain the dominant factors in the RMK in the project. Based on the results of the research, it was found that the main factor as a constraint in the Contract Quality Plan in this project was the Delay in Delivery of Materials which had an average value of 2,700 and the smallest was the material standard required to no longer be in the market with an average value of 2,133.
