The number of platforms currently makes it easier for users to provide reviews, one of which is the Bukalapak application on the Google Play Store. While both negative and positive reviews can influence the value of the app, users can also be affected by the app's sentiment reviews. Therefore it is necessary to carry out sentiment analysis to classify negative and positive reviews. This research uses review data of 1000 reviews and then classifies them using the RapidMiner application using three methods, namely KNN, Naive Bayes, and also the Decision Tree. The results of the KNN method obtained accuracy values of 85.03%, precision of 84.98%, and recall of 100.00%, then for the Naive Bayes method obtained accuracy values of 73.95%, precision of 100.00%, and recall of 69.26%, and for the Decision Tree method obtained 89.12% accuracy value, 88.62% precision, and 100.00% recall. this can prove that the Decision Tree method is superior to the KNN method and also the Naive Bayes method.
目前平台的数量使用户更容易提供评论,其中之一是谷歌Play商店上的Bukalapak应用程序。虽然负面和正面评价都会影响应用程序的价值,但用户也会受到应用程序情绪评价的影响。因此,有必要进行情绪分析,对负面评价和正面评价进行分类。本研究使用了1000条评论的评论数据,然后使用RapidMiner应用程序,使用三种方法对其进行分类,即KNN、Naive Bayes和决策树。KNN方法的结果获得了85.03%的准确度值、84.98%的准确度和100.00%的召回率,Naive Bayes方法获得了73.95%的准确度、100.00%的准确度,和69.26%的召回率;决策树方法获得了89.12%的准确率值、88.62%的准确度以及100.00%的回收率。这可以证明决策树方法优于KNN方法和Naive Bayes方法。

In Indonesia, the theft rate is still quite high. According to Bappeda data, cases of theft still tend to be high. In 2019, there were 362,000 cases of theft. CCTV use is still ineffective because at the time of the theft of goods, we only know the goods taken and the perpetrators. In order to catch the perpetrators and return the goods, it is necessary to process them first and find the location of the perpetrators themselves. Therefore, we propose an idea entitled "Activation Control System in Motorized Vehicles Using GPS". Where this tool will detect the position of a vehicle so that this vehicle remains in a restricted area. When this vehicle leaves the restricted area, the GPS system will send a signal explaining that the vehicle is leaving the area. So, if there is a theft, when the vehicle has moved away from about 50 meters from the area that has been locked, a notification will appear which will be displayed on the web application. The research stages that we will work on are first identifying the equipment and systems that will be used and conducting a study of the technology literature that will be developed, then identifying the theoretical and empirical system design and knowing the basic elements. Then master and understand the characterization of components and analyze the main functions so that they can work properly. Then do modelling and simulation and ensure that the components to be developed can work properly. And the final stage is to ensure that the system equipment is valid and reliable. Based on the results of the study, it shows that the system is active when the actual position away from the locked position/area as far as 100 meters has successfully functioned. Where the information changes to "Out of reach" from the previous "Within Reach" and there are notifications in the form of sound and vibration to increase security from theft.
在印度尼西亚,盗窃率仍然很高。根据巴佩达的数据,盗窃案件仍然居高不下。2019年,共有36.2万起盗窃案件。闭路电视的使用仍然无效,因为在货物被盗时,我们只知道被拿走的货物和肇事者。为了抓住肇事者并归还货物,有必要首先对其进行处理,并亲自找到肇事者的位置。因此,我们提出了一个题为“使用GPS的机动车辆激活控制系统”的想法。该工具将检测车辆的位置,从而使该车辆保持在禁区内。当车辆离开禁区时,GPS系统将发送一个信号,说明车辆正在离开禁区。因此,如果发生盗窃,当车辆离开被锁定区域约50米时,会出现一个通知,并显示在网络应用程序上。我们将进行的研究阶段首先是确定将要使用的设备和系统,并对将要开发的技术文献进行研究,然后确定理论和经验系统设计,并了解基本要素。然后掌握和理解组件的特性,分析主要功能,使其能够正常工作。然后进行建模和仿真,确保要开发的组件能够正常工作。最后一个阶段是确保系统设备的有效性和可靠性。根据研究结果,表明当距离锁定位置/区域100米的实际位置成功运行时,该系统是活动的。如果信息从以前的“触手可及”更改为“遥不可及”,并且有声音和振动形式的通知,以提高防盗性。

Transaction Data Security Using AES and RC4 使用AES和RC4的事务数据安全
Pub Date : 2023-01-04 DOI: 10.24114/cess.v8i1.41212
Puji Sari Ramadhan, Muhammad Syahril, Rini Kustini, H. Winata, Robin Darwis Gea
This study discusses the effectiveness of using AES (Advanced Encryption Standard) and RC4 (Rivest Chipper 4) as digital data security algorithms to prevent and protect transaction data from irresponsible parties. This needs to be done because the development of sales transactions or other services has used digital technology a lot. This situation causes the need to secure digital data from existing transactions, so that transaction data can be stored safely. Transaction data security is carried out by changing data into ciphers or codes that are difficult to read using the AES (Advanced Encryption Standard) and RC4 (Rivest Cipher 4) algorithms. This research begins by collecting existing transaction data and then transforming it into ASCII code. The results of the transformation will be used to perform calculations using the AES algorithm. After completing the calculation process using the AES algorithm, then do the calculations using RC4. These results will be stored in the database so that the transaction data that has turned into these codes cannot be known by other parties. The combination of the AES and RC4 algorithms is carried out to strengthen data encryption because there are more and more rotation systems and double security is carried out so that digital data is not easily read and misused. With the presence of this research, it can be shown that the AES and RC4 algorithms are capable of encrypting existing transaction data with multiple levels of security. 
本研究讨论了使用AES(高级加密标准)和RC4(Rivest Chipper 4)作为数字数据安全算法来防止和保护交易数据免受不负责任方的攻击的有效性。之所以需要这样做,是因为销售交易或其他服务的发展已经大量使用了数字技术。这种情况导致需要保护现有交易中的数字数据,以便安全地存储交易数据。交易数据安全是通过使用AES(高级加密标准)和RC4(Rivest密码4)算法将数据更改为难以读取的密码或代码来实现的。这项研究首先收集现有的交易数据,然后将其转换为ASCII代码。转换的结果将用于使用AES算法进行计算。使用AES算法完成计算过程后,使用RC4进行计算。这些结果将存储在数据库中,以便其他方无法知道已转换为这些代码的交易数据。AES和RC4算法的结合是为了加强数据加密,因为有越来越多的轮换系统,并且执行双重安全,使得数字数据不容易被读取和滥用。通过这项研究,可以表明AES和RC4算法能够以多个安全级别加密现有的交易数据。

Most of the campus area introduction media use brochures to provide information to prospective students. This media among teenagers is no longer attractive. Most prospective students prefer information through multimedia such as short videos. Due to the limited time of video media, very little content is provided so that delivery will be very less. The use of Virtual Tour 360 multimedia technology will help to provide clear information in the form of text and the application of Point tracking technology will make it easier for users to feel like they are in a campus environment. The methodology used in making this application is the Luther-Sutopo version of the Multimedia Development Life Cycle (MDLC). The 360 Degree Panorama Virtual Tour Application Introduction to the Siliwangi University Campus is expected to make it easier to convey information that can be easily accepted by users. This application can see a real environment simulation on the Siliwangi University campus by representing information in the form of 360° panoramic images making it easy to display information visually. The test results obtained from the alpha test of the application of Point tracking can make it easier for users to run the application and the beta test results that the application functions very well get a score of 83.75%. 
大多数校园介绍媒体都使用小册子向未来的学生提供信息。这种媒体在青少年中不再有吸引力。大多数准学生更喜欢通过短视频等多媒体获取信息。由于视频媒体的时间有限,提供的内容很少,因此交付量会非常少。Virtual Tour 360多媒体技术的使用将有助于以文本的形式提供清晰的信息,而点跟踪技术的应用将使用户更容易感觉自己身处校园环境中。制作该应用程序所使用的方法是Luther Sutopo版本的多媒体开发生命周期(MDLC)。Siliwangi大学校园的360度全景虚拟旅游应用介绍有望使用户更容易传达易于接受的信息。该应用程序通过以360°全景图像的形式表示信息,可以在Siliwangi大学校园内看到真实的环境模拟,从而易于直观地显示信息。点跟踪应用程序的阿尔法测试结果可以让用户更容易地运行应用程序,应用程序功能良好的贝塔测试结果获得83.75%的分数。

Posyandu adalah sebuah kegiatan dari contoh upaya kesehatan bersumberdaya masyarakat yang memberikan layanan kesehatan dasar untuk masyarakat yang dilaksanakan oleh masyarakat itu sendiri dalam memberdayakan dan memberikan keringanan kepada masyarakat dalam bidang kesehatan. Untuk menciptakan posyandu yang cerdas dan sehat, serta memajukan citra posyandu, Dinas Kesehatan, Kabupaten Banyuasin mengadakan lomba posyandu. Tujuan diadakannya lomba posyandu ini adalah untuk memaksimalkan kemampuan posyandu sebagai pionir melayani kesehatan bagi ibu dan anak. Namun penentuan posyandu terbaik masih belum efektif dan optimal, karena pihak Dinas Kesehatan mengalami kesulitan dalam menentukan posyandu terbaik, dikarenakan terdapat banyak posyandu yang harus dilakukan penilaian dan kerap kali terjadi kesalahan saat melakukan penilaian yang menyebabkan penentuan posyandu terbaik tidak tepat dan akurat. Penelitian ini memberikan solusi dengan mengimplementasikan sebuah sistem yang biasa dikenal dengan Sistem Pendukung Keputusan (SPK) sebagai teknologi informasi untuk meningkatkan kualitas keputusan bersumber pada pemakaian sistem serta untuk mempermudah pihak Dinas Kesehatan, Kabupaten Banyuasin dalam mengambil keputusan untuk penentuan posyandu terbaik di Kabupaten Banyuasin. Penelitian ini memberikan hasil suatu SPK Penentuan Posyandu Terbaik dengan menerapkan metode Simple Additive Weighting (SAW). Kata Kunci: Sistem Pendukung Keputusan, Posyandu, Simple Additive Weighting, Waterfall
Posyandu是一个社区健康努力的例子,它为社区提供基本卫生服务,为社区本身提供权力和自由。为了创建聪明健康的posyandu,以及促进posyandu的形象,卫生服务,banyutan区域组织了posyandu竞赛。posyandu竞赛的目的是最大限度地提高posyandu作为母亲和孩子健康服务的先锋的能力。但是,健康服务部门在确定最佳的位置方面遇到了困难,因为有很多posyandu需要评估,而做最好的posyandu往往是错误的,导致最好的posyandu的判断是不准确和准确的。本研究通过实施一种通常被称为决策支持系统(SPK)的信息技术来提高系统分配的决策质量,并让banyutan学区更容易做出决定,从而确定banyutan选区中最好的posyandu。这项研究通过采用简单的上瘾方法来确定Posyandu最好的结果。关键词:支持决策系统,Posyandu,简单的adpositive weighing, Waterfall
