ERP stands for enterprise resource planning. It is an information system that is all rolled into one, is very flexible and adaptable, and optimizes business operations while also centralizing all of the company's data. This study aims to empirically investigate the elements that affect users' intention and usage of enterprise resource planning (ERP). This research incorporates self-efficacy into the unified theory of acceptance and use of technology (UTAUT2). A quantitative technique was taken, and as a result, 143 replies that might be used were effectively collected. After that, the information was put through a structural equation modelling partial least square (SEM-PLS) analysis. According to the findings of this research, self-efficacy appears to have a significant influence on all endogenous variables (EE, BI, and UB), as indicated by t-values of 3.951, 7.573, and 5.492, respectively. In addition, the analysis also indicated that PE (4.317), EE (2.397), and HM (3.084) are likewise statistically and substantively significant to BI. The result shows that the R2 for BI and UB indicate a moderate impact of 0.603 and 0.521, respectively. It is suggested that the model has valuable applications in academic and real-world contexts.

引用

IOP Conference Series: Materials science and engineering 2018年第1期407卷

作者： J Robecca D Sudrajat Study Program of Industrial Engineering Faculty of Engineering and Computer Science Universitas Komputer Indonesia Jl. Dipatiukur no. 112-116 Bandung Indonesia

The purpose of this study is to minimize the purchase cost for each food from the catering menu. Therefore, raw material inventory control method is needed to plan arrival schedule, order schedule, and the amount of ordering of each foodstuff. The technique of determining the amount of ordering (lotting technique) used there are three, namely the least unit cost technique, the lot for lot technique and the least total cost technique. The results of this study indicate that the company can minimize the cost of purchasing food based on lead time, storage time limit, and optimal lotting techniques. Lead time is the period between the order to the delivery time, the storage time limit is how long the best time required for the quality of foodstuffs are maintained, while the lotting technique is the optimal size of order quantity. The lotting technique chosen for each type of food material is different. The cost of purchasing the food consists of the price of the foodstuff, the ordering fee for the type of material and the storage cost for the type of foodstuff. There are 16 types of foodstuffs with the cost of purchasing the smallest raw material with the lot for lot techniques. There are 29 types of foodstuffs with the cost of purchasing the smallest raw materials using the least unit cost techniques. And 10 types of foodstuffs with the least total cost technique as a lotting technique with the purchase of the smallest raw material. Of the 55 types of food raw materials, the company was able to save the cost of purchasing groceries of 33,006,371.75 IDR per month. Of course, in order to apply this planning, the company must provide facilities in order to extend the life of the foodstuff in accordance with predetermined lead time and to ensure the quality of the foodstuff is guaranteed.

Nasution Informatics Engineering Master Program Faculty of Computer Science and Information Technology Universitas Sumatera Utara Medan Indonesia Data Science and Artificial Intelligence Faculty of Computer Science and Information Technology Universitas Sumatera Utara Medan Indonesia

The lowest time search in the dataset that E. Taillard utilized employs a heuristic approach based on tabu search techniques to get the predicted solution. Glover’s study gives a broad description of tabu search, which is commonly encountered in Taillard’s job shop scheduling difficulties and Widmer et al.’s flow shop sorting challenges. Although tabu search is relatively simple to use and typically yields excellent results, it takes a long time to complete. In this research a hybrid ACO and PSO was carried out to minimize makespan in the Job Shop Scheduling Problem which was used as sourced from benchmark data which is secondary data obtained from E. Taillard “Benchmarks for basic scheduling problems” which consists of job shop matrix data (job × machine) measuring 4 × 4, 5 × 5, 7 × 7, 10 × 10, 15 × 15, 20 × 20, 30 × 15, 30 × 20, 50 × 15 and 50 × 20. Hybrid is carried out by calculating the Pbest value, namely the process position of each job on the machine to get the best solution using the PSO algorithm. Next, calculate the Gbest (Global best) value for the position of each job on the best machine on the entire machine using the PSO algorithm and initialize the ACO parameters using the PBest and Gbest values. The results of research on datasets with sizes 10×10, 15×15, 20×20, 30×15, 30×20, 50×15 and 50×20 produce smaller makespan compared to the lower bound on the dataset with an average minimum makespan improvement value of 1.184.

Fuzzy logic can be used to represent obscurity based on terms such as high, old, hot, cold, and so on. Fuzzy logic can extend the range of truth values to all real numbers in intervals between 0 and 1. Numbers in this interval represent the possibility that the statement given is 'true' or 'wrong'. The use of fuzzy logic can be used in everyday life, such as in the fields of medicine, engineering, agriculture, transportation, environmental science and also in economic and business applications. As in this study, it was used to calculate the ideal amount of 'tips' for restaurant waiters based on the service provided by restaurant waiters. The method used in this study is to use Mamdani fuzzy logic with the process of defuzzyfication using the Centroid of area (COA). The results of this study are that it can be determined the value crisp of giving tips to restaurant waiters is 45 thousand rupiah provided that the service provided for service = 7 (Excellent) and food service = 8 (Delicious)..

IOP Conference Series: Materials science and engineering 2021年第4期1098卷

作者： I Sulistiyowati F A Hanif M Nasar M P T Sulistyanto M Ahsan Faculty of Science and Technology University of Muhammadiyah Sidoarjo Sidoarjo Indonesia Electrical Engineering University of Muhammadiyah Malang Malang Indonesia Informatics Study Program Faculty of Science and Technology Universitas Kanjuruhan Malang Malang Indonesia

Communication is important in human life because communication can bridge all forms of ideas to be conveyed by someone. And the communication media commonly used today are via mobile phones, which can be via SMS messages, WhatsApp, or telephone. The problem is, in some areas the absence of signals or blank spots is a problem for those who rely on communication via mobile phones. For this reason, it is necessary to optimize the short message media in the Arduino and Bluetooth-based blank spot areas. Here the main goal is to make it easier for humans to communicate via mobile phones even in difficult conditions and without a data packet or WIFI signal. The tools used are android, the Lo-Ra module as a long-distance wireless transmission technology platform that can reach distances of 10km, and then also use the Arduino Pro Mini as a microcontroller board and Bluetooth terminal that functions to transmit data from android to Arduino and then forward it to Lo Ra. From the test results, it was found that this tool works well in the blank spot area or difficult to signal, without the need for data packages or WIFI we can still communicate well through the short message media on the cell phone. From the test results, it was found that this tool works well in the blank spot area or difficult to signal, without the need for data packages or WIFI we can still communicate well through the short message media on the cell phone. So, with the invention of this tool, we can still communicate through the medium of short messages even though we are in the blank spot area, and even when we do not have a data package or WIFI.

There has been a growing interest in Health informatics applications, research, and education within the Middle East and North African Region over the past twenty years. People of this region share similar cultural and religious values, primarily speak the Arabic language, and have similar health care related issues, which are in dire need of being addressed. Health informatics efforts, organizations, and initiatives within the region have been largely under-represented within, but not ignored by, the International Medical informatics Association (IMIA). Attempts to create bonds and collaboration between the different organizations of the region have remained scattered, and often, resulted in failure despite the fact that the need for a united health informatics collaborative within the region has never been more crucial than today. During the 2017 MEDINFO, held in Hangzhou, China, a new organization, the Middle East and North African Health informatics Association (MENAHIA) was conceived as a regional non-governmental organization to promote and facilitate health informatics uptake within the region endorsing health informatics research and educational initiatives of the 22 countries represented within the region. This paper provides an overview of the collaboration and efforts to date in forming MENAHIA and displays the variety of initiatives that are already occurring within the MENAHIA region, which MENAHIA will help, endorse, support, share, and improve within the international forum of health informatics.

A comprehensive approach utilizing quantum machine learning in the study of corrosion inhibition on quinoxaline compounds

Artificial Intelligence Chemistry

引用

Artificial Intelligence Chemistry 2024年第2期2卷

作者： Muhamad Akrom Supriadi Rustad Hermawan Kresno Dipojono Ryo Maezono Study Program in Informatics Engineering Faculty of Computer Science Universitas Dian Nuswantoro Semarang 50131 Indonesia Research Center for Materials Informatics Faculty of Computer Science Universitas Dian Nuswantoro Semarang 50131 Indonesia Quantum and Nano Technologies Research Group Faculty of Industrial Technology Institut Teknologi Bandung Bandung 40132 Indonesia School of Information Science Japan Advanced Institute of Science and Technology Ishikawa 923-1292 Japan

In this investigation, a quantitative structure-property relationship (QSPR) model coupled with a quantum neural network (QNN) was used to explore the corrosion inhibition efficiency (CIE) of quinoxaline compounds. Integrating quantum chemical properties (QCP) features reduced computational burden by strategically reducing the features from 11 to 4 while maintaining prediction accuracy. QNN models outperform traditional methods like artificial neural networks (ANN) and multilayer perceptron neural networks (MLPNN), with a coefficient of determination (R 2 ) value of 0.987, coupled with diminished root mean square error (RMSE), mean absolute error (MAE), and mean absolute deviation (MAD) values of 0.97, 0.92, and 1.10, respectively. Predictions for six newly synthesized quinoxaline derivatives: quinoxaline-6-carboxylic acid (Q1) , methyl quinoxaline-6-carboxylate (Q2) , (2 E ,3 E )-2,3-dihydrazono-1,2,3,4-tetrahydroquinoxaline (Q3) , (2 E ,3 E ) 2,3-dihydrazono-6-methyl-1,2,3,4-tetrahydroquinoxaline (Q4) , ( E )-3-(4-methoxyethyl)-7-methylquinoxalin-2(1 H)-one (Q5) , and 2-(4-methoxyphenyl)-7-methylthieno[3,2- b ] quinoxaline (Q6) , show remarkable CIE values of 95.12, 96.72, 91.02, 92.43, 89.58, and 93.63 %, respectively. This breakthrough technique simplifies testing and production procedures for new anti-corrosion materials.

Bisindo or Bahasa Isyarat Indonesia is one of sign language methods in Indonesia, besides SIBI or Sistem Isyarat Bahasa Indonesia. Generally, Bisindo is used by deaf people in their daily communication. Deaf people tend to have barriers to communicate with others. Yet, in the educational realm, some of them still have high spirit to continue their education until university. So, they must improve their abilities or competences in communicating with others and try to get information from around the world, for example using sophisticated technology with sign language. Information system of sign language learning is important to help deaf and heard people who want to understand the deaf conversation meaning. Bisindo information system is in website form that is built by PHP, MySQL, and sublime text 3. Based on the black box method, the Bisindo information system can run well. The results of the trial to the user describe that the maximum percentage for each level of testing is above 50% except for testing of conformity with the needs of deaf only at maximum of 42%. The Bisindo information system still has weakness, but it already gives benefits especially for deaf people in Indonesia.
