The human face has various functions, especially in expressing something. The expression shown has a unique shape so that it can recognize the atmosphere of the feeling that is being felt. The appearance of a feeling is usually caused by emotion. Research on the classification of emotions has been carried out using various methods. For this study, a Convolutional Neural Network (CNN) method was used which serves as a classifier for sad and depressive emotions. The CNN method has the advantage of preprocessing convolution so that it can extract a hidden feature in an image. The dataset used in this study came from the Facial expression dataset image folders (fer2013) where the dataset used for classification was taken with a ratio of 60% training and 40% validation with the results of the trained model of 60% total loss and 68% test accuracy.
人脸有多种功能,尤其是在表达某些东西时。所显示的表情具有独特的形状,因此它可以识别所感受到的感觉的氛围。一种感觉的出现通常是由情绪引起的。关于情绪分类的研究已经用各种方法进行了。在本研究中,使用卷积神经网络(CNN)方法作为悲伤和抑郁情绪的分类器。CNN方法具有预处理卷积的优点,可以提取图像中的隐藏特征。本研究使用的数据集来自面部表情数据集图像文件夹(fer2013),其中用于分类的数据集以60%的训练和40%的验证比例进行,训练后的模型总损失为60%,测试准确率为68%。

Various kinds of activities in the fields of communication, information, transportation, banking, education, and those that require high mobility, require a supporting technology to do so. The supporting technology is a smartphone, where this smartphone is almost owned by every level of society. Smartphones are widely used in education to support learning between lecturers and students. At the University of Singaperbangsa Karawang Faculty of Computer Science, there is one aspect of student assessment that is measured based on the number of students pre-sent. The attendance system that runs at the Singaperbangsa University of Karawang, Faculty of Computer Science, has not yet implemented smartphone technology in its implementation. The problems that arise with the attendance system at this time is the presence data that has no backup if lost and absenteeism records that are easily damaged. Therefore the design and manufacture of the NFC Presence application is carried out to overcome this problem. The NFC Pres-ence application was built using the Mobile Application Development Life Cycle (MADLC) method. NFC (Near Field Communication) on smartphones and NFC Card is a tool to support student attendance data, which will then be stored properly in the database to prevent student attendance data loss. The attendance pro-cess in the NFC Presence application is done by mentoring an NFC card containing data in accordance with the data-base to the lecturer smartphone. Furthermore, the lecturer smartphone will send attendance data to the database, so that this data can be accessed anytime, anywhere.
通信、信息、交通、银行、教育等领域的各种活动,以及那些需要高流动性的活动,都需要一种支持技术来实现。支持技术是智能手机,智能手机几乎被社会各个阶层所拥有。智能手机在教育中被广泛使用,以支持教师和学生之间的学习。在新加坡大学(University of singapore)卡拉旺大学(bangsa Karawang)计算机科学学院,学生评估的一个方面是根据出席的学生人数来衡量的。在新加坡卡拉旺邦沙大学计算机科学学院运行的考勤系统尚未在其实施中使用智能手机技术。此时考勤系统出现的问题是考勤数据一旦丢失就没有备份,考勤记录容易损坏。因此,为了克服这一问题,进行了NFC临在应用程序的设计和制造。NFC存在应用程序是使用移动应用程序开发生命周期(MADLC)方法构建的。智能手机和NFC卡上的NFC(近场通信)是一种支持学生出勤数据的工具,然后将这些数据正确存储在数据库中,以防止学生出勤数据丢失。NFC Presence应用程序中的出勤过程是通过根据数据库将包含数据的NFC卡指导到讲师智能手机来完成的。此外,讲师智能手机将考勤数据发送到数据库,以便随时随地访问这些数据。

Lecturers are one of the main actors in universities. Lecturer performance can affect the quality of a college. Because the quality of higher education is strongly influenced by the lecturers, the performance of the lecturers needs to be assessed. Lecturer performance can be assessed by evaluating the lecturer's performance in teaching. Lecturer performance can be evaluated by classifying student assessments of lecturers. Lecturers are assessed based on how the lecturer mastered the material, the lecturer's discipline in teaching, and the presentation of the material. The process of grouping lecturer scores can be done using the K-Means algorithm. K-Means is a popular clustering algorithm that performs well. K-Means requires a parameter that is K or the number of clusters. The importance of the number of clusters so that there is a need for optimization in determining the number of K. In this study, optimization was carried out using the Elbow method so as to produce the ideal number of groups of 4 groups. The results of the clustering evaluation calculated using the SSE were 54.4% which showed that the results were not optimal. The results of the cluster evaluation are not optimal due to the lack of data for the K-Means application.
讲师是大学的主要角色之一。讲师的表现会影响一所大学的教学质量。由于讲师对高等教育质量的影响很大,因此需要对讲师的绩效进行评估。可以通过评价讲师在教学中的表现来评价讲师的绩效。讲师的表现可以通过学生对讲师的评价进行分类来评估。对讲师的评估是基于讲师对材料的掌握程度、讲师的教学纪律以及材料的呈现。分组讲师分数的过程可以使用K-Means算法来完成。K-Means是一种性能良好的流行聚类算法。K- means要求参数为K或簇数。由于簇数的重要性,使得在确定k的个数时需要进行优化。本研究采用肘部法进行优化,从而产生4个组的理想组数。使用SSE计算的聚类评价结果为54.4%,表明结果并不理想。由于缺乏K-Means应用的数据,聚类评估的结果不是最优的。

Human needs are the reason technology is developing rapidly. One of the benefits of technological development is making information very easy to obtain. Everyone can get various kinds of information, such as searching for a list of houses, rented houses to boarding houses. Many people get that information easily, but not a few people have difficulty getting the same information. One example that often occurs is overseas students who find it difficult to get boarding information. Indraprasta University students complain that it is difficult to get information on boarding houses that are close to campus. From this problem, it prompted the author to create an Android-based Boarding House Search Application. In making this application the author uses Android Studio as a code editor, and exchanges data on the web service using JSON. Searching for boarding houses in this application uses two ways, first a boarding search based on a list and second a boarding house search based on the user's closest location. The menu on the main page makes this application easy to use by anyone.
人类的需求是技术迅速发展的原因。技术发展的好处之一是使信息很容易获得。每个人都可以得到各种各样的信息,比如搜索房屋列表,出租房屋到寄宿房屋。许多人很容易获得这些信息,但也有不少人很难获得同样的信息。经常发生的一个例子是海外学生发现很难获得住宿信息。因德拉普拉斯塔大学的学生抱怨说,很难获得离校园近的寄宿公寓的信息。从这个问题出发,促使作者开发了一个基于android的寄宿公寓搜索应用程序。在制作此应用程序时,作者使用Android Studio作为代码编辑器,并使用JSON在web服务上交换数据。在此应用程序中搜索寄宿公寓使用两种方式,第一种是基于列表的寄宿搜索,第二种是基于用户最近位置的寄宿公寓搜索。主页上的菜单使这个应用程序易于任何人使用。

Reading is a basic skill that children must have, because reading all knowledge will quickly enter and be understood by humans. To improve children's reading skills, it is necessary to have learning methods and media that are in accordance with the needs and development of children. Technological developments have made cellphones that were previously only used for calling and sending messages now become smartphones that have more features such as being able to do office work, video calls, games and much more. One of the most widely used smartphones and the most widely used by Indonesians is the Android-based smartphone. The ABACA application is an android-based reading learning application or knowing the alphabet. The application has been tested using the black box method with the results that all menu or application content is functioning properly. The hope of developing this application is that it can attract children's interest, especially preschool or kindergarten children, to get to know the alphabet with the application display in the form of an interesting animated image. The ABACA app is equipped with a game menu to train your child to connect words and spell letters of the alphabet. The test results with the black box method on the ABACA application show that the menu is appropriate and functions properly as expected in the design document.
