In every educational institution, especially universities, there are lots of scholarships offered to students. Likewise with the Prabumulih College of Engineering (STIT Prabumulih) which has a scholarship program for its students by applying predetermined rules or criteria, for example, parents' income, parents' dependents, student achievement index scores, etc. Due to this, not all scholarship recipients who apply for scholarships will receive a scholarship. The problem faced by the campus today is in the process of winning scholarships. therefore a decision support system is needed that can assist in providing scholarship recipient recommendations. In this study the authors used the AHP method and the Expert Choice application. From the calculation results obtained by the specified criteria, the GPA of 0.389 is the highest priority weight compared to other criteria. Then, from the results of calculating student data or all alternatives, the total value of each student is obtained. It can be concluded that the one who can be recommended to get a UKT scholarship is Student A because it has the highest score, namely 16.6% of the total calculated.
在每一个教育机构,尤其是大学,有很多奖学金提供给学生。同样,Prabumulih工程学院(STIT Prabumulih)也为学生提供奖学金计划,该计划采用预定的规则或标准,例如父母的收入、父母的家属、学生的成就指数分数等。因此,并非所有申请奖学金的奖学金获得者都能获得奖学金。今天校园面临的问题是在争取奖学金的过程中。因此,需要一个决策支持系统,可以帮助提供奖学金获得者推荐。在本研究中,作者采用了层次分析法和专家选择法。从指定标准得到的计算结果来看,GPA 0.389是相对于其他标准的最高优先级权重。然后,从计算学生数据或所有选项的结果中,得到每个学生的总价值。可以得出结论,可以推荐获得UKT奖学金的是学生a,因为他的分数最高,占总分的16.6%。

The use of credit cards is increasing in today's digital era. This increase has resulted in many cases of fraud which have had a negative impact on credit card owners. To overcome this, many financial institutions have developed credit card fraud detection systems that can identify suspicious transactions. This study uses a classification method, namely random forest and decision tree to identify illegal transactions using a credit card, which then compares the results and attempts to create a model that can be useful for detecting fraud using a credit card that is more accurate and effective. The result of this study is that the accuracy provided by the Decision Tree Classifier is 0.98, while the accuracy provided by the Random Forest Classification is also 0.975. The conclusion obtained that the decision tree has a higher level of accuracy compared to the Random Forest Classification Algorithm, which is 98%. On the other hand, the Random Forest classification algorithm has a slightly lower level of accuracy compared to the Decision Tree classification algorithm, with an accuracy rate of 97.5%

Cardiomegaly is a disease in which sufferers show no symptoms and have symptoms such as shortness of breath, abnormal heartbeat and edema. Cardiomegaly will cause the sufferer's heart to pump harder than usual. Early diagnosis of cardiomegaly can help make decisions about whether the heart is abnormal or normal. In addition, due to the problem that manual examination takes time and requires human interpretation and experience, tools are needed to automatically develop and identify normal and abnormal hearts. Therefore, this study proposes cardiac chamber segmentation using 2D (two-dimensional) ultrasound convolutional neural networks for rapid cardiomegaly screening in clinical applications based on heart ultrasound examination. The proposed approach uses a CNN with a U-Net architecture model with abnormal and normal heart data. The research results obtained used the pixel matrix evaluation Avg_accuracy of 99.50%, Val_accuracy of 97.98% and Mean_IoU of 90.01%.
心脏肥大症是一种没有症状的疾病,患者会出现呼吸短促、心跳异常、水肿等症状。心脏肿大会导致患者的心脏跳动比平时更剧烈。心脏肿大的早期诊断有助于判断心脏是异常还是正常。此外,由于人工检查费时,需要人工解释和经验,因此需要工具来自动开发和识别正常和异常的心脏。因此,本研究提出在心脏超声检查的基础上,利用二维(二维)超声卷积神经网络进行心室分割,在临床应用中快速筛查心脏肿大。该方法使用具有U-Net结构的CNN模型来处理异常和正常的心脏数据。采用像素矩阵评价得到的研究结果Avg_accuracy为99.50%,Val_accuracy为97.98%,Mean_IoU为90.01%。

Emotions are a person's response to an event. Emotions can be expressed verbally or nonverbally. Over time people can express their emotions through social media. Considering that emotion is a reflection of society's response, it is important to classify emotions in society to find out the community's response as information for consideration in decision-making. This study is aimed to identify and analyze the datasets, methods, and evaluation metrics that are being used in the classification of emotional texts in textual data from research data from 2013 to 2022. Based on the inclusion and exclusion design in selecting literature, a total of 50 kinds of literature were used in extracting and synthesizing data. Analysis of the data shows that out of 50 pieces of literature, there are 36 works of literature that use public datasets while 14 kinds of literature use private datasets. In the method of developing models for classifying, the SVM and Naive Bayes models are the most popular among the other models. In evaluating the model, the F-measure or F1-score metric is the most widely used metric compared to other metrics. There are three main contributions identified in this study, namely methods, models, and evaluation

Data analysis and processing is very important to support business development. One example is The Javanese Café which requires analysis and processing to determine promotional menu package recommendations. To carry out data analysis and processing, of course you need technology to make these activities easier. The technology that can be used to overcome this problem is data mining. Data mining has an association rule method which functions to form association patterns. Researchers also use the FP-Growth algorithm to speed up the data processing process. The sales transaction data processing resulted in 14 association patterns with the highest confidence values and 9 menu items with the lowest support values. Then the results were analyzed again and produced 4 recommendations for promotional menu packages that could be used to support product marketing strategies.

In the current digital era, information availability is abundant, and news serves as a primary source of up-to-date and reliable information for the public. However, with the increasing volume of information, a robust evaluation method is necessary to ensure accurate and dependable news labeling. This research employs a machine learning approach, utilizing three common classification algorithms: Naive Bayes, SVM, and Random Forest, to evaluate news labels based on their titles. The dataset utilized in this study is obtained from Jakarta AI Research and consists of 10,000 samples covering various news topics. Evaluation is conducted using accuracy, precision, recall, and F1-Score metrics to gain a comprehensive understanding of the classification algorithm's performance. The results of this research demonstrate that the SVM algorithm exhibits the best performance, achieving an accuracy rate of 92.92%. Random Forest follows with an accuracy rate of 91.21%, and Naive Bayes with an accuracy rate of 89.61%. These findings provide deep insights into the effectiveness of the machine learning approach in evaluating news labels based on their titles. Furthermore, the study highlights the importance of considering other evaluation metrics such as precision, recall, and F1-Score to obtain a more holistic understanding of the algorithm's performance. Further research is encouraged to involve additional classification algorithms and more diverse and extensive datasets to enhance the comprehension of news label evaluation comprehensively. Such endeavors can significantly contribute to the development of automated systems for classifying news with higher accuracy and reliability in the future

Facial Expression Recognition (FER) is currently widely explored by researchers in the field of Computer Vision. The application of Machine Learning and Deep Learning methods is useful in developing an intelligent system that is accurate in recognizing facial expressions such as emotions. This is inseparable from the type of dataset and classification method used which certainly affects the desired results. To choose the right method, it is necessary to compare the performance of these methods. This study focuses on comparing the performance results of four classification methods namely, Convolutional Neural Network (CNN), Support Vector Machine (SVM), K-Nearest Neighbor (KNN), Naïve Bayes Classifier (NBC) on a multiclass dataset for seven classes of facial emotion labels based on Eigenface feature selection uses the Personal Component Analysis (PCA) algorithm. The test parameters used to perform method comparisons are accuracy, recall, precision, f1-score, as well as the Receiving Operating Characteristic (ROC) and Area Under Curve (AUC) curves. The results of the analysis state that the SVM method has the highest accuracy value, while other methods show varying performance based on recall, precision, f1-score, and ROC and AUC analysis. This research was conducted on the FER 2013 dataset which showed that the classification method tested had quite good performance according to the test parameters.
面部表情识别(FER)是目前计算机视觉领域研究人员广泛探索的领域。机器学习(Machine Learning)和深度学习(Deep Learning)方法的应用有助于开发能够准确识别情绪等面部表情的智能系统。这与使用的数据集类型和分类方法是分不开的,这当然会影响期望的结果。为了选择正确的方法,有必要对这些方法的性能进行比较。本研究重点比较了卷积神经网络(CNN)、支持向量机(SVM)、k -近邻(KNN)、Naïve贝叶斯分类器(NBC)四种分类方法在多类数据集上对基于特征脸特征选择的七种面部情绪标签的性能结果,并使用个人成分分析(PCA)算法。用于进行方法比较的测试参数是准确性,召回率,精密度,f1分数,以及接收工作特征(ROC)和曲线下面积(AUC)曲线。分析结果表明,SVM方法具有最高的准确率值,而其他方法在召回率、精度、f1-score、ROC和AUC分析等方面表现各异。本研究在fer2013数据集上进行,结果表明,根据测试参数,所测试的分类方法具有相当好的性能。

The Sumba region, Indonesia, is known for its extraordinary natural beauty and unique cultural richness. There are 19 interesting tourist attractions spread throughout the area, but tourists often face difficulties in planning efficient visiting routes. From this case, it can be solved by applying graph theory in terms of searching for the shortest distance which is completed using the shortest path search algorithm. Then these 19 tourist objects are used to build a weighted graph, where the nodes represent the tourist objects and the edges of the graph describe the distance or travel time between these objects. Therefore, this research aims to compare the shortest path search algorithm with parameters to compare the shortest distance results, algorithm complexity and execution time for tourism in the Sumba area. The results of this research involve a comparison of several shortest path search algorithms, with the aim of finding the shortest distance results, algorithm complexity, and execution time for tourism in the Sumba area. Based on the test results of the five algorithms with the parameters that have been prepared, and the findings show that each algorithm has its own characteristics, the results are as follows: Dijkstra's algorithm can be used to calculate the shortest route for single-source and single-destination types. This resembles the Bellman-Ford algorithm, only the Bellman-Ford algorithm can be used simultaneously on graphs that have negative weight values. Meanwhile, the Floyd-Warshall algorithm is suitable for use on the all-pairs type. Then, the Johnson Algorithm can be used to determine the shortest path from all pairs of paths where the destination node is located in the graph. Finally, the Ant Colony algorithm to compute from a node to each pair of destination nodes.
印度尼西亚的松巴地区以其非凡的自然美景和独特的文化底蕴而闻名。该地区共有19个有趣的旅游景点,但游客在规划有效的旅游路线时往往面临困难。在这种情况下,可以用图论来求解搜索最短距离的问题,用最短路径搜索算法来完成。然后用这19个旅游对象构建一个加权图,其中节点表示旅游对象,图的边描述这些对象之间的距离或旅行时间。因此,本研究旨在将最短路径搜索算法与参数进行比较,比较Sumba地区旅游的最短距离结果、算法复杂度和执行时间。本研究的结果包括几种最短路径搜索算法的比较,目的是找出Sumba地区旅游的最短距离结果、算法复杂度和执行时间。根据所准备的参数对五种算法的测试结果,发现每种算法都有自己的特点,结果表明:Dijkstra算法可用于计算单源单目的类型下的最短路由。这类似于Bellman-Ford算法,只有Bellman-Ford算法可以同时用于具有负权重值的图。同时,Floyd-Warshall算法适用于全对类型。然后,使用Johnson算法从图中目标节点所在的所有路径对中确定最短路径。最后,用蚁群算法从一个节点计算到每对目标节点。
