Research on fingerprints has been done a lot, this is because of so many uses of fingerprints as an access tool to enter a system. This method is used to ensure the authenticity of authorized users. Fingerprints are used as biometric identification because fingerprints have a unique pattern that is different from every human fingerprint. The many uses of fingerprint biometric systems also cause many threats to the system, fingerprint forgery occurs so that it can be used to access the system illegally. Therefore this study proposes a system to be able to recognize the authenticity of a fingerprint. CNN is generally designed for object recognition of an image, making it suitable for recognizing fingerprint images to determine if a fingerprint is genuine or fake. The results of the evaluation of several experiments conducted obtained the highest accuracy value of 95.32% for determining the authenticity of fingerprints.
关于指纹的研究已经做了很多,这是因为很多人使用指纹作为进入系统的访问工具。该方法用于保证授权用户的真实性。指纹被用作生物特征识别,因为指纹具有独特的模式,不同于每个人的指纹。指纹生物识别系统的众多应用也给系统带来了诸多威胁,指纹伪造的现象时有发生,从而可以被利用来非法进入系统。因此,本研究提出了一种能够识别指纹真伪的系统。CNN一般是为图像的物体识别而设计的,适合用于识别指纹图像来判断指纹的真假。通过对多次实验的评价,得出指纹真伪鉴定的最高准确率为95.32%。

The use of a Learning Management System (LMS) in e-learning makes it easier for teachers to track and record student learning behavior. The right analytics of e-learning students can help teachers understand the student context and what learning experiences are most suitable for e-learning students to improve learning outcomes. However, e-learning teachers often experience difficulties in analyzing student data due to a large number of students who must be analyzed and limited data. To support research in this area, we conducted a descriptive analysis of a dataset containing student data from the Open and Distance Learning (ODL) that organizes e-learning. The dataset contains data on student demographic profiles and student activity or behavior during e-learning which is recorded in the LMS system at the Open University of Indonesia. In this initial study, the dataset contained information from 120 classes in 18 subjects with 4,741 students from 33 study programs with many logs on LMS 1,641,234 entries. This article presents an analytical description of the characteristics of students participating in e-learning using Exploratory data analytics (EDA) and machine learning approaches as the basis for predictive and prescriptive analytics of student learning outcomes based on a combination of demographic profile data and learning behavior. This study helps education practitioners in the first step of analytics data as the basis for developing e-Learning instructional designs that support the success of fully online students.
在电子学习中使用学习管理系统(LMS)使教师更容易跟踪和记录学生的学习行为。对e-learning学生进行正确的分析,可以帮助教师了解学生的情境,了解哪些学习体验最适合e-learning学生,从而提高学习效果。然而,由于需要分析的学生数量众多,数据有限,使得e-learning教师在分析学生数据时往往遇到困难。为了支持这一领域的研究,我们对一个数据集进行了描述性分析,该数据集包含来自组织电子学习的开放和远程学习(ODL)的学生数据。该数据集包含印度尼西亚开放大学LMS系统中记录的学生人口统计概况和电子学习期间的学生活动或行为数据。在最初的研究中,数据集包含来自18个学科的120个班级的信息,来自33个学习项目的4,741名学生,LMS上有1,641,234个条目。本文使用探索性数据分析(EDA)和机器学习方法对参与电子学习的学生的特征进行分析描述,作为基于人口统计资料数据和学习行为相结合的学生学习结果预测和规范分析的基础。这项研究帮助教育从业者在分析数据的第一步,作为开发电子学习教学设计的基础,支持完全在线学生的成功。

YouTube is one of the most effective social media sites for promoting products, one of which is movies. The film industry usually publishes video trailers on YouTube to promote their upcoming film. The comments that appear on YouTube could help movie producers to estimate how the public will react to their movie once it is released. In this study, we conducted a sentiment analysis on the comments of Indonesian movie trailers on YouTube. We split movie comments into four popular movie genres: action, romance, comedy, and horror. Then, we use the Delta TF-IDF word weighting method and combine it with several classification methods to compare the model performance. Finally, we evaluated the model using Stratified K-Fold cross-validation with K = 10. Results showed that Logistic Regression and Naïve Bayes are better when classifying sentiment for a specific genre. Simultaneously, the SVM model gives good performance on sentiment analysis for a more general genre.
YouTube是推广产品最有效的社交媒体网站之一,其中之一就是电影。电影行业通常在YouTube上发布视频预告片来宣传他们即将上映的电影。出现在YouTube上的评论可以帮助电影制片人估计电影上映后公众的反应。在本研究中,我们对YouTube上印尼电影预告片的评论进行了情感分析。我们将电影评论分为四种流行的电影类型:动作片、爱情片、喜剧片和恐怖片。然后,我们使用Delta TF-IDF单词加权方法,并将其与几种分类方法相结合,比较模型的性能。最后,我们使用分层K- fold交叉验证(K = 10)对模型进行评估。结果表明,逻辑回归和Naïve贝叶斯在对特定类型的情感进行分类时效果更好。同时,支持向量机模型在更一般的体裁情感分析上也有很好的表现。

User feedback is one of the most important sources of information for improving the quality of software products. Our current research focuses on a software product that is often used in many universities, the E- Learning system. To reduce the effort of manually reading all submitted user feedback, building an automatic text classification using various machine learning approaches is a popular solution. However, there is often a challenge of imbalanced data that could jeopardize the ability of the machine to find the pattern and classify feedback correctly. Several techniques ranging from random resampling of data to artificially creating more data (e.g. SMOTE) have already been proposed for handling imbalanced data and show promising results in terms of performance. This paper aims to implement several numerical representations and implementing resampling techniques (to handling imbalanced data), which then are followed by evaluating some popular supervised machine learning classification algorithms, which are the Logistic Regression, Random Forest, Support Vector Machine, Naive Bayes, and Decision Tree. Finally, evaluating performance with and without using resampling techniques by macro-average F1 Scores. The results show generally the implementation of oversampling techniques leads to better performance, except in a few cases where under-sampling techniques perform better.
用户反馈是提高软件产品质量最重要的信息来源之一。我们目前的研究重点是一个经常在许多大学使用的软件产品,电子学习系统。为了减少手动阅读所有提交的用户反馈的工作量,使用各种机器学习方法构建自动文本分类是一种流行的解决方案。然而,经常存在数据不平衡的挑战,这可能会危及机器找到模式并正确分类反馈的能力。从随机重新采样数据到人为创建更多数据(例如SMOTE),已经提出了几种技术来处理不平衡数据,并在性能方面显示出有希望的结果。本文旨在实现几种数值表示和实现重采样技术(以处理不平衡数据),然后评估一些流行的监督机器学习分类算法,这些算法是逻辑回归,随机森林,支持向量机,朴素贝叶斯和决策树。最后,通过宏观平均F1分数评估使用和不使用重采样技术的性能。结果表明,一般来说,过采样技术的实现会带来更好的性能,除了在少数情况下,欠采样技术表现得更好。

These days, human-computer interactions develop in an alarmingly fast rate. To keep up with this development, one of many things to be advanced is machine's capability of recognizing human emotions through speech, or simply put, Speech Emotion Recognition (SER). Various studies regarding SER have been carried out using varying data modalities, such as TV shows, movies, and actor voice recordings. While the result may be proven satisfying, to collect these data of TV and actor recordings can be quite difficult and may require some costs. On the other hand, YouTube is an open and free platform for data gathering, and retrieving data from YouTube is effortless as well. Despite that, almost none of SER studies have tried this method of data collecting. This paper presents SER in Indonesian language, using Indonesian YouTube Web Series dataset with 4 labels of emotions. In the beginning, several experiments were carried out to determine which deep learning approach trained with which specific combination of features would yield out the most favorable result. The initial stage of the experiments showed that the Convolutional Neural Network (CNN) using a feature combination of MFCC, Contrast, and Tonnetz, gives better performance than other deep learning approach that we use. After tuning parameter process, we obtain that CNN with the combination of MFCC, Contrast, and Tonnetz gives 62.30% of F1 - Score.
如今,人机交互正以惊人的速度发展。为了跟上这一发展,机器通过语音识别人类情感的能力,或者简单地说,语音情感识别(SER)是许多需要改进的东西之一。关于SER的各种研究使用了不同的数据模式,例如电视节目、电影和演员的录音。虽然结果可能令人满意,但收集电视和演员录音的这些数据可能相当困难,可能需要一些成本。另一方面,YouTube是一个开放和免费的数据收集平台,从YouTube上检索数据也毫不费力。尽管如此,几乎没有SER研究尝试过这种数据收集方法。本文使用带有4个情感标签的印度尼西亚YouTube Web Series数据集来呈现印度尼西亚语的SER。一开始,我们进行了几个实验,以确定哪种深度学习方法使用哪种特定的特征组合进行训练会产生最有利的结果。实验的初始阶段表明,使用MFCC、Contrast和Tonnetz的特征组合的卷积神经网络(CNN)比我们使用的其他深度学习方法提供了更好的性能。经过参数调整处理,我们得到MFCC、Contrast和Tonnetz组合的CNN给出了62.30%的F1 - Score。

The Digital Based Community Economy Program has been created to expand market access and improve the quality of farmers. The program is called the “Online Farming Program”, in collaboration with the Ministry of Communication and Information Technology, as well as several digital business startups who have created mobile-based applications that aim to increase productivity in agriculture and advance farmers. Standard of living. However, the socialization of the Go-Online Farmers program, which is still not optimal for farmers who are not familiar with computer programs and are not familiar with technology is one of the obstacles they face. So in the era of the industrial revolution 4.0, the Participatory Rural Appraisal (PRA) and Media Production Concept (MPC) methods were used so that the output generated from this study could educate and add to the information obtained by farmers and help farmers buy and sell online so they could use the Go-Online program maximally. It can be concluded that from this research a strategy is needed to disseminate the Go-Online Farmer Program to farmers so that researchers implement a video motion graphic to facilitate this research which is uploaded to the YouTube channel so that information can be disseminated, readily accepted, and distributed to 88.813 villages in Indonesia.
建立了基于数字的社区经济计划,以扩大市场准入并提高农民的素质。该计划被称为“在线农业计划”,是与通信和信息技术部以及几家数字创业公司合作开展的,这些初创公司开发了基于移动的应用程序,旨在提高农业生产力并帮助农民。生活水平。然而,对于不熟悉计算机程序和不熟悉技术的农民来说,上网农民计划的社会化仍然不是最理想的,这是他们面临的障碍之一。因此,在工业革命4.0时代,我们使用了参与式农村评估(PRA)和媒体生产概念(MPC)方法,使本研究产生的产出能够教育和增加农民获得的信息,并帮助农民在线购买和销售,从而最大限度地利用Go-Online计划。从这项研究中可以得出结论,需要一种策略来向农民传播Go-Online Farmer Program,以便研究人员使用视频动态图形来促进这项研究,并将其上传到YouTube频道,以便信息可以传播,易于接受,并分发到印度尼西亚的88.813个村庄。

Dew computing is one of the distributed computing paradigms which is considered as an extension of the cloud computing paradigm. In dew computing, users can perform full system functionality without depending on internet availability. All data will be stored on the local storage of the user's device, and when an internet connection is available, synchronization will be carried out to synchronize the information on cloud-based applications. There have been many implementations of dew computing in existing applications, but research done in the field of dew computing is not as much as in other distributed computing fields. This study intends to discuss the dew computing concept and its implementation, what constraints might exist on implementation, and what strategies need to be considered in designing dew computing implementations. The results is a proposed framework for consideration on determining the specifications of applications running on dew computing, both for desktop, mobile and cloud environments, which covered four aspects, which are: data storage, synchronization, authorization and collaboration.
露水计算是分布式计算范式之一,被认为是云计算范式的扩展。在露水计算中,用户可以执行完整的系统功能,而不依赖于互联网的可用性。所有数据都将存储在用户设备的本地存储中,当互联网连接可用时,将进行同步,以同步基于云的应用程序上的信息。在现有的应用中已经有很多露珠计算的实现,但是在露珠计算领域的研究并不像在其他分布式计算领域那样多。本研究旨在讨论露水计算的概念及其实现,在实现中可能存在哪些约束,以及在设计露水计算实现时需要考虑哪些策略。研究结果提出了一个框架,用于确定运行在露水计算上的应用程序的规范,包括桌面、移动和云环境,它涵盖了四个方面,即:数据存储、同步、授权和协作。

Indonesian populace demands animal protein high enough to fulfill nutrition, one of the most sought-after sources of protein comes from beef. Due to high market needs, some traders are defrauding to get higher profits. This has caused discomfort for most beef consumers because people generally rely on the ability of vision to find out the quality of meat. In order to make it easier for the public to recognize the quality of meat to be consumed, this study classifies the quality of meat marbling based on the size of marbling. The classification in this study used the SVM algorithm, LDA, and Decision Tree. Furthermore, the result came out with the best algorithm in this case was the Decision Tree.
