Social media has become a communication key to spark thinking, dialogue and action around social issues. Hoax is information that added or subtracted from the content of the actual news. The spread of unconfirmed Covid-19 news can cause public concern. The purpose of this research was to modify KNN with Jaccard Space in the classification of hoax news related to Covid-19. The data used from Jabar Saber Hoaks and Jala Hoaks. The classification results with KNN with Jaccard Space and stemming Nazief & Adriani get the highest accuracy than other models in this research. The accuracy of the KNN model on the Jaccard Space with stemming Nazief & Adriani and K = 5 was 75.89%, while for Naïve Bayes was 65.18%.
社交媒体已成为围绕社会问题引发思考、对话和行动的沟通关键。恶作剧是指在实际新闻内容中添加或减去的信息。未经证实的新冠肺炎消息的传播可能引起公众关注。本研究的目的是利用Jaccard Space对与新冠肺炎相关的恶作剧新闻进行分类,修改KNN。使用的数据来自Jabar Saber Hoaks和Jala Hoaks。与本研究中的其他模型相比,使用带有Jaccard Space的KNN和词干Nazief&Adriani的分类结果获得了最高的准确度。在Jaccard空间上,以Nazief和Adriani为词尾,K=5的KNN模型的准确率为75.89%,而对于Naïve Bayes,准确率为65.18%。

 Laptop is a desktop personal computer (PC) whose dimensions are reduced to increase flexibility in its use. However, the large number of products will make it difficult for consumers to choose a laptop that suits the needs of consumers who want to buy it.The purpose of this research is to help buyers who want to buy laptop products according to their needs by making a Decision Support System (DSS). There are 12 criteria considered in this research, price, processor, RAM capacity, hard disk capacity, SSD capacity, V-RAM capacity, maximum RAM upgrade capacity, laptop weight, screen size, screen type, screen refresh rate, and screen resolution. Choosing a laptop product there is a criterion value of a laptop product and a value of preference criteria from the buyer as a decision maker. Also the criteria values on laptop products have different contributions to the overall value of the laptop product. Thus, the methods used are Analytical Hierarchy Process (AHP), Profile Matching (PM) with linear interpolation, and Simple Addictive Weighting (SAW) to determine the recommended options. Lastly, SPK that has been made will be able to provide recommendations best alternative choices and best suit the needs of buyers for selecting laptop products.

Learning using video media such as watching videos on YouTube is an alternative method of learning that is often used. However, there are so many learning videos available that finding videos with the right content is difficult and time-consuming. Therefore, this study builds a recommendation system that can recommend videos based on courses and syllabus. The recommendation system works by looking for similarity between courses and syllabus with video annotations using the cosine similarity method. The video annotation is the title and description of the video captured in real-time from YouTube using the YouTube API. This recommendation system will produce recommendations in the form of five videos based on the selected courses and syllabus. The test results show that the average performance percentage is 81.13% in achieving the recommendation system goals, namely relevance, novelty, serendipity and increasing recommendation diversity.
使用视频媒体学习,比如在YouTube上看视频,是一种常用的学习方法。然而,有这么多的学习视频,找到合适的视频内容是困难和耗时的。因此,本研究构建了一个基于课程和教学大纲的视频推荐系统。推荐系统通过使用余弦相似度方法寻找课程和教学大纲与视频注释之间的相似性来工作。视频注释是使用YouTube API从YouTube实时捕获的视频的标题和描述。该推荐系统将根据所选课程和教学大纲以五个视频的形式提出推荐。测试结果表明,在实现推荐系统目标,即相关性、新颖性、偶然性和增加推荐多样性方面,平均性能百分比为81.13%。

The continuous growth of the internet has led to the use of social media for various purposes increase. For instance, some irresponsible parties take advantage of the comment feature on social media platforms to harm others by providing spam comments on the shared object. Furthermore, variation of comments creates many features to be processed, thereby negatively impacting the performance of a classification algorithm. Therefore, this study aims to solve the problem associated with spam comments by comparing filter and wrapper based feature selection using text classification techniques. Data collected from training and test data of 4944 and 100 comments showed that the best accuracy, precision, recall, and f-measure of MNB are 96%, 100%, 92%, and 95.8%. The best accuracy is achieved using feature selection by combining Chi-Square and Sequential Forward Selection methods with a subset of 500 features. Furthermore, the accuracy increase in the MNB and SVM classifications are 8% and 4%. This research concludes that the combination of feature selection improves the classification performance of Indonesian language spam comments.
互联网的持续增长导致社交媒体用于各种目的的使用增加。例如,一些不负责任的各方利用社交媒体平台上的评论功能,通过在共享对象上提供垃圾邮件评论来伤害他人。此外,评论的变化会产生许多待处理的特征,从而对分类算法的性能产生负面影响。因此,本研究旨在通过比较使用文本分类技术的基于过滤器和包装器的特征选择来解决与垃圾邮件评论相关的问题。从4944条和100条评论的训练和测试数据中收集的数据显示,MNB的最佳准确度、准确度、召回率和f-measure分别为96%、100%、92%和95.8%。通过将卡方和顺序正向选择方法与500个特征的子集相结合,使用特征选择来实现最佳准确度。此外,MNB和SVM分类的准确率分别提高了8%和4%。本研究得出结论,特征选择的结合提高了印尼语垃圾邮件评论的分类性能。

Someone's opinion on a product or service that is poured through a review is something that is quite important for the owner or potential customer. However, the large number of reviews makes it difficult for them to analyze the information contained in the reviews. Aspect-based sentiment analysis is the process of determining the sentiment polarity of a sentence based on predetermined aspects.This study aims to analyze an Indonesian restaurant review using a combination of Convolutional Neural Network and Contextualized Word Embedding models. Then it will be compared with a combination of Convolutional Neural Network and Traditional Word Embedding models. The result of aspect-classification on three models; BERT-CNN, ELMo-CNN, and Word2vec-CNN give the best results on the ELMo-CNN model with micro-average precision of 0.88, micro-average recall of 0.84, and micro-average f1-score of 0.86. Meanwhile, the sentiment-classification gives the best results on the BERT-CNN model with a precision value of 0.89, a recall of 0.89, and an f1-score of 0.91. Classification using data without stemming have almost similar results, even better than using data with stemming.
某人对产品或服务的意见通过评论倾泻而出,这对店主或潜在客户来说是相当重要的。然而,大量的评论使得他们很难分析评论中包含的信息。基于方面的情感分析是基于预先确定的方面来确定句子的情感极性的过程。本研究旨在使用卷积神经网络和情境化词嵌入模型的组合来分析印尼餐厅评论。然后将其与卷积神经网络和传统词嵌入模型的组合进行比较。三种模型的方面分类结果;BERT-CNN、ELMo-CNN和Word2vec-CNN在ELMo-CNN模型上的效果最好,微平均精度为0.88,微平均召回率为0.84,微平均f1-score为0.86。同时,情感分类在BERT-CNN模型上得到了最好的结果,精度值为0.89,召回率为0.89,f1得分为0.91。使用不带词干提取的数据进行分类的结果几乎相似,甚至比使用带词干提取的数据更好。

Nowadays, internet has become the most popular source of news. However, the validity of the online news articles is difficult to assess, whether it is a fact or a hoax. Hoaxes related to Covid-19 brought a problematic effect to human life. An accurate hoax detection system is important to filter abundant information on the internet.  In this research, a Covid-19 hoax detection system was proposed by transfer learning of pre-trained transformer models. Fine-tuned original pre-trained BERT, multilingual pre-trained mBERT, and monolingual pre-trained IndoBERT were used to solve the classification task in the hoax detection system. Based on the experimental results, fine-tuned IndoBERT models trained on monolingual Indonesian corpus outperform fine-tuned original and multilingual BERT with uncased versions. However, the fine-tuned mBERT cased model trained on a larger corpus achieved the best performance.
如今,互联网已经成为最受欢迎的新闻来源。然而,无论是事实还是骗局,网络新闻文章的有效性都很难评估。与新冠肺炎有关的骗局给人类生活带来了问题影响。一个准确的恶作剧检测系统对于过滤互联网上丰富的信息非常重要。在本研究中,通过预先训练的变压器模型的迁移学习,提出了一种新冠肺炎恶作剧检测系统。使用微调的原始预训练BERT、多语言预训练mBERT和单语预训练IndoBERT来解决恶作剧检测系统中的分类任务。基于实验结果,在单语印尼语语料库上训练的微调IndoBERT模型优于未封顶版本的微调原始和多语言BERT。然而,在更大的语料库上训练的微调mBERT案例模型获得了最佳性能。

The performance appraisal process in Religious High Court Bandar Lampung has not been carried out objectively, but rather a subjectivity element (relationship closeness). Some employees occupy structural positions but do not fulfil competence and promotion principles, so that it has an impact on providing promotion to a position in the judiciary. Multiple Linear Regression method can provide a predictive model for employee recommendations entitled to occupy positions in the agency. The method implementation using SPSS produces an equation Y = 74.177 + 0.035X1 + 0.020X2 - 0.026X3 + 0.045X4 + 0.001X5. This equation is applied to the employee performance values, and it is obtained from 40 employees 26 employees deserve to be given recommendations promotion. Regression performance testing results using 10-cross validation get the correlation coefficient value is 80.66% with MAE value of 2.24% and RMSE 3.88%, which mean has good performance.
班达尔·楠榜宗教高等法院的绩效评估过程并不是客观地进行的,而是一个主观因素(关系亲密度)。一些雇员担任结构性职位,但不符合能力和晋升原则,因此对司法部门职位的晋升产生了影响。多元线性回归方法可以为有权在机构中任职的员工推荐提供预测模型。利用SPSS软件实现方法,得到方程Y=74.177+0.035X1+0.020X2-0.026X3+0.045X4+0.001X5。该方程应用于员工绩效值,从40名员工中得出26名员工值得推荐晋升。使用10交叉验证的回归性能测试结果得到的相关系数为80.66%,MAE值为2.24%,RMSE值为3.88%,平均值具有良好的性能。

Hiragana and katakana handwritten characters are often used when writing words in Japanese. Japanese itself is often used by native Japanese as well as people learning Japanese around the world. Hiragana and katakana characters themselves are difficult to learn because many characters are similar to one another. In this study, hiragana and basic katakana, dakuten, handakuten, and youon were used, which were taken from the respondents using a questionnaire. This study used the CNN method which will be compared with a combination of the CNN and SVM methods which have been designed to identify each character that has been prepared. Preprocessing of character images uses the methods of image resizing, grayscaling, binarization, dilation, and erosion. The preprocessed results will be input for CNN as a feature extraction tool and SVM as a tool for character recognition. The results of this study obtained accuracy with the following parameters: 69×69 image size, 3 patience values, val_loss monitor callbacks, Nadam optimization function, 0.001 learning rate value, 30 epochs value, and SVM RBF kernel. If using a system that only uses the CNN network, the accuracy is 87.82%. The results obtained when using a combination of CNN and SVM were 88.21%.
在日语中书写单词时经常使用平假名和片假名手写字符。日本人和世界各地学习日语的人经常使用日语。平假名和片假名字符本身很难学习,因为许多字符彼此相似。在这项研究中,使用了平假名和基本片假名、dakuten、handakuten和youon,这些都是使用问卷从受访者中获取的。本研究使用了CNN方法,该方法将与CNN和SVM方法的组合进行比较,后者被设计用于识别已准备的每个字符。字符图像的预处理采用图像大小调整、灰度缩放、二值化、膨胀和侵蚀等方法。预处理后的结果将被输入CNN作为特征提取工具,SVM作为字符识别工具。本研究的结果在以下参数下获得了准确性:69×69图像大小、3个耐心值、val_loss监视器回调、Nadam优化函数、0.001学习率值、30个历元值和SVM RBF核。如果使用仅使用CNN网络的系统,准确率为87.82%。使用CNN和SVM组合时获得的结果为88.21%。

Social media has become more critical for people to communicate about the pandemic of COVID-19. In social media, hashtags are social annotations which often used to denote message content. It serves as an intuitive and flexible tool for making huge collections of posts searchable on Twitter. Through practices of hashtagging, user representations of a given post also become connected. This study aimed to analyze the hashtag of Indonesian COVID-19 Tweets using Social Network Analysis (SNA). We used SNA techniques to visualize network models and measure some centrality to find the most influential hashtag in the network. We collected and analyzed 500.000 public tweets from Twitter based on COVID-19 keywords. Based on the centrality measurement result, the hashtag #corona is a hashtag with the most connection with other hashtags. The hashtag #COVID19 is the hashtag that is most closely related to all other hashtags. The hashtag #corona is the hashtag that most acts as a bridge that can control the flow of information related to COVID-19. The hashtag #coronavirus is the most important of hashtags based on their link. Our study also found that the hashtag #covid19 and #wabah have a substantial relationship with religious-related hashtags based on network visualization.
社交媒体对人们交流新冠肺炎疫情变得更加重要。在社交媒体中,标签是社交注释,通常用于表示消息内容。它是一个直观而灵活的工具,可以在Twitter上搜索大量帖子。通过标签的实践,给定帖子的用户表示也变得相连。本研究旨在使用社交网络分析(SNA)分析印尼新冠肺炎推文的标签。我们使用SNA技术来可视化网络模型,并测量一些中心性,以找到网络中最具影响力的标签。我们收集并分析了50万条基于新冠肺炎关键词的推特公共推文。根据中心性测量结果,#corona标签是与其他标签联系最多的标签。#COVID19标签是与所有其他标签关系最密切的标签。#corona标签是最能起到桥梁作用的标签,可以控制与新冠肺炎相关的信息流。#coronavirus标签是基于其链接的最重要的标签。我们的研究还发现,基于网络可视化,#covid19和#wabah标签与宗教相关标签有着实质性的关系。

Exploring MSMEs Cybersecurity Awareness and Risk Management : Information Security Awareness 中小微企业网络安全意识与风险管理探索:信息安全意识
Pub Date : 2021-07-31 DOI: 10.22146/IJCCS.67010

The use of information technology in the management of Micro, Small, and Medium Enterprises (MSMEs) is not limited to business performance and productivity but also aspects of data security and transactions using various mobile, website, and desktop-based applications. This article offers an idea to explore cybersecurity awareness and risk management of MSME actors who adopt information technology. The research method used is qualitative with a case study approach in the Coffeeshop X business and the Y Souvenir business in Salatiga City, Central Java, Indonesia. The data collection technique used in-depth interviews, observation, and document studies. These findings indicate that Cybersecurity Awareness, especially information security awareness, can be reviewed based on knowledge, attitudes, and behavior. Risk management can be review based on supply risk, operational risk, and customer risk. Cybersecurity Awareness and Risk Management in MSMEs is holistic and cannot be generalized, so it needs to be discussed contextually based on case studies. In the context of Coffeeshop X and Souvenir Y, the level of Cybersecurity Awareness (knowledge, attitude, behavior) is not always linear. In addition, risk management is more dominant in the customer risk dimension, compared to supply risk and operational risk. 
在微型、小型和中型企业(MSME)的管理中使用信息技术不仅限于业务绩效和生产力,还包括使用各种移动、网站和桌面应用程序的数据安全和交易方面。本文提供了一个探索采用信息技术的中小微企业参与者的网络安全意识和风险管理的想法。在印度尼西亚中爪哇省萨拉蒂加市的Coffeeshop X企业和Y纪念品企业中,所使用的研究方法是定性的,并采用了案例研究方法。数据收集技术采用了深入访谈、观察和文献研究。这些发现表明,网络安全意识,特别是信息安全意识,可以根据知识、态度和行为进行审查。风险管理可以根据供应风险、运营风险和客户风险进行审查。中小微企业的网络安全意识和风险管理是全面的,不能一概而论,因此需要在个案研究的基础上结合具体情况进行讨论。在Coffeeshop X和Souvenir Y的背景下,网络安全意识(知识、态度、行为)的水平并不总是线性的。此外,与供应风险和运营风险相比,风险管理在客户风险维度上更占主导地位。
