Abstract

The use of information technology these days are very high. From business through education activities tend to use this technology most of the time. Information technology uses computer networks for integration and management data. To avoid business problems, the number of network devices installed requires a manageable network configuration for easier maintenance. Traditionally, each of network devices has to be manually configured by network administrators. This process takes time and inefficient. Network automation methods exist to overcome the repetitive process. Design model uses a web-based application for maintenance and automates networking tasks. In this research, the network automation system implemented and built a controller application that used REST API (Representational State Transfer Application Programming Interface) architecture and built by Django framework with Python programming language. The design modeled namely As-RaD System. The network devices used in this research are Cisco CSR1000V because it supports REST API communication to manage its network configuration and could be placed on the server either. The As-RaD System provides 75% faster performance than Paramiko and 92% than NAPALM.

Abstract

Stocks are securities as legal proof of company ownership. Such ownership is traded in the stock exchange only for public companies. A capital market is an activity that accommodates the desire to invest. Traders look for profits by taking advantage of stock movements that always experience fluctuating changes using technical analysis. The problem is how traders decide to buy a stock at an uncertain price. Brown's Weighted Exponential Moving Average (B-WEMA) method has the advantage of a better accuracy level, which is considered able to help with stock price prediction problems. The Levenberg-Marquardt (LM) algorithm has the advantage of optimizing its accuracy; therefore, it is proposed to be used as an optimization method to predict stock prices. The B-WEMA method with LM optimization improves the accuracy of stock price predictions, thereby reducing risks and increasing trading success. Results show the minimum difference of actual prices, and its prediction was 4.03%. The smallest error from MSE and MAPE were 719.56 and 1.99%, respectively.

Abstract

Mycobacterium tuberculosis is a pathogenic bacterium that causes respiratory tract disease in the lungs, namely tuberculosis (TB). The problem is to find out the bacterial colonies when the observation is still done manually using a microscope with a magnification of 1000 times. It took a long time and was tiring for the observer's eye. Based on this background, an automatic detection system for Mycobacterium tuberculosis was designed. Mycobacterium tuberculosis image data were obtained from the Semarang City Health Center. The dataset used is 220 sputum images, which are divided into 180 training data and 40 testing data. The method used in this research is a combination of Convolutional Neural Network (CNN) and K-Nearest Neighbor (KNN). CNN is used for image feature extraction. Furthermore, the results of the CNN feature extraction are classified using the KNN. The results of the accuracy of the combination of CNN-KNN and CNN were also compared. The stages of the process are color transformation, feature extraction, and data training with CNN, then classification with KNN. The results of the classification test between CNN and the CNN-KNN combination show that the CNN-KNN combination is better. The result of CNN-KNN accuracy is 92.5%, while CNN's accuracy is 90%.

Abstract

The assessment of academic articles is based on the number of citations, but the number only is not enough. So now there is Altmetric which can measure the impact of academic articles from the number of citations and using social media, usually Twitter. Still, the number of mentions on Twitter is not enough because the expressions of the sentences vary. Mentions must be classified according to neutral, positive, and negative criteria. Sentiment analysis is performed on tweets to measure social media volume and attention related to research findings from academic articles. There are many sentiment analysis methods, so this study aims to compare sentiment analysis methods using Decision Tree, K-NN, Naïve Bayes, and Random Forest to get the most suitable methods. The evaluation method in this study uses the Confusion Matrix by searching for Accuracy, Precision, and Recall values. The results show that the most suitable sentiment analysis method is Naïve Bayes by obtaining the highest classification suitability value of the other methods, which has an actual positive sentiment value of neutral 2056, positive 1200, and negative 1292. In addition, Naïve Bayes gets the highest accuracy score of 95, 45%.

Abstract

ISO 21001 refers to the standardization of educational organization management and is an international standard, making it mandatory to be implemented in higher education institutions. Along with this, the rapid development of Information Systems and Information Technology (IS/IT) today has changed the paradigm of education and provided a new perspective that IS/IT support not only aids the learning process but also various other areas in higher education. Standardization focusing on this field includes IT Governance (ITG) COBIT 2019 and ISO 27001. Therefore, the researcher conducted a study to analyze which tools are most correlated with the implementation of ISO 21001, so that the findings of this research can provide recommendations that can serve as a basis for policy in selecting the appropriate standardization tools. The research method used is ex post facto. The analysis was conducted using SmartPLS. The researcher designed a questionnaire instrument to be distributed to the population of the Department of Computer Engineering and Informatics Engineering, UNDIP Semarang. The results of the questionnaire will then be tested for validity and reliability, followed by a correlation test while considering the T-Value. Based on the analysis results, it was concluded that both COBIT 2019 and ISO 27001 have an influence on ISO 21001. The influence of COBIT 2019 on ISO 21001 is significant, with a path coefficient and p-value of 0.000, while the influence of ISO 27001 shows a p-value of only 0.091.

Abstract

Indonesia is the world’s largest coconut producer. As a result, coconuts play an important role in sustaining millions of Indonesians' livelihoods. In 2021, a fear of cooking oil emerged, leading to a decline in production levels, reduced income for individuals, and an increase in commodity pricing both domestically and internationally. The scarcity of cooking oil, notwithstanding Indonesia's position as the leading global producer, indicates an imbalance between supply and demand. This research aims to investigate production problems as the root cause of coconut industry shortages, identify productivity-related issues through a literature review, and assess the urgency of the criteria presented in five Linkert scales. Listing problems is critical for determining the root of the problem, as well as the potential for increasing revenue and ensuring long-term sustainability through value-added initiatives in the green supply chain management (GSCM) scope. This study uses TOPSIS and MOORA analysis, a way of making decisions based on levels of importance and enabler barriers in the coconut industry, focusing on production and productivity.
