Elevating the quality of learning is central to ensuring academic programs align with national standards. One crucial aspect of this process is the semester-based learning planning. Traditionally, the Department of Computer Science orchestrates this planning by creating separate documents for various data points, including courses, CPL (Graduate Learning Outcomes), and CPMK (Course Learning Outcomes), which are then integrated into the RPS (Semester Learning Plan) document each term. This study seeks a solution to enhance the efficiency of such data management through the development of an admin module. The system, designed using the Rapid Test Development (RAD) approach and the Laravel framework, offers a more effective data management solution, subsequently elevating the pedagogical quality of the Department of Computer Science. In conclusion, an integrated approach to data management can make a significant contribution to educational quality. Through this research, the scholarly contribution provided is the introduction of a systematic model in educational data management to boost the efficiency and effectiveness of the learning process in higher education institutions
提高学习质量是确保教学计划符合国家标准的核心。这一过程的一个重要方面是基于学期的学习规划。传统上,计算机科学系通过为各种数据点(包括课程、CPL(毕业生学习成果)和 CPMK(课程学习成果))创建单独的文档来协调这种规划,然后将其整合到每学期的 RPS(学期学习计划)文档中。本研究寻求一种解决方案,通过开发一个管理模块来提高此类数据管理的效率。该系统采用快速测试开发(RAD)方法和 Laravel 框架设计,提供了一个更有效的数据管理解决方案,从而提升了计算机科学系的教学质量。总之,数据管理的综合方法可以为提高教学质量做出重大贡献。通过这项研究,我们的学术贡献是在教育数据管理中引入了一个系统模型,以提高高等教育机构学习过程的效率和效果。

The Consumer Price Index is one of the indicators used to confirm financial success in inflation management. This study aims to help determine the CPI prediction value in Indonesia for the next twelve periods in a month using the ARIMA (Autoregressive Integrated Moving Average) method using the data from January 2015 to March 2022. The results obtained show that the best model that can be used for forecasting is the ARIMA model (2,1,2) with drift with Akaike's Information Criterion (AIC) values of 2190.84. The results of Indonesia's accurate CPI forecasting can be used to assess inflation management for policymaking in the context of controlling inflation.It can be concluded that Based on the analysis, the optimal ARIMA model for forecasting Indonesia's CPI is ARIMA (2,1,2) with drift, aiding in evaluating inflation management for policymaking
消费者价格指数是用来确认通货膨胀管理财务成功的指标之一。本研究旨在利用2015年1月至2022年3月的数据,使用ARIMA(自回归综合移动平均)方法,帮助确定印度尼西亚未来12个月的CPI预测值。结果表明,具有漂移的ARIMA模型(2,1,2)是预测的最佳模型,赤池信息准则(Akaike’s Information Criterion, AIC)值为2190.84。印度尼西亚准确的CPI预测结果可用于评估通货膨胀管理,为控制通货膨胀的政策制定提供参考。通过分析可知,预测印尼CPI的最优ARIMA模型为带有漂移的ARIMA(2,1,2),有助于评估通胀管理,为政策制定提供依据

Proxmox has a feature that can build a private network in it. Each host on a private network on Proxmox generally shares physical resources, including network connections using a virtual network, one of which is a VLAN. The Proxmox server supports Open VSwitch as a virtual switch. Open virtual switch, an alternative virtual switch quite popular among cloud developers, can be a solution for managing traffic between Virtual Machins and external communications. The method used in this study is the Network Development Life Cycle (NDLC). After applying the automation engine using Ansible, it overcame the problem, namely speeding up configuration and reducing human error or errors in configuring virtual networks. The automation system can speed up the virtual network management process compared to the manual method based on 5 (five) experiments, namely when the manufacturing operation has an average time of 08 minutes and 42 seconds faster. Whereas when the addition operation has an average faster time of 08 minutes 17 seconds. On the other hand, when the deletion operation has an average time of 42 seconds faster.

In this present paper, we consider some features of the states of one-dimensional photonic crystals. Form the numerical results performed by transfer matrix method in periodic multilayer structure made of titanium dioxide and tellurium material, it is found that the structure possesses a photonic band gap it was determined that the structure has a photonic band gap in the borderline visible and infrared spectral region. Our predictions were in good agreement with the photonic bandgap tuning. Our simple model can also predict and explain the effect of incidence angle and wavelength and number of layers on the photonic bandgap. We expect such structures to play an important role in micromechanical tunable optical sensors and filters.

The current state of the COVID-19 pandemic makes the University of Lampung conduct learning activities by network (online).The area and number of buildings' public facilities will be an issue for new students and visitors since it takes longer to find information, explore, and understand the layout of the building environment. To address these issues, there is a need for technology that fulfills the requirements of information, efficiency, and new methods in introducing a building to visitors. These problems are expected to be resolved by developing a virtual 3D map application for Building A, the Dean of the Faculty of Engineering, and Building B the architectural engineering. The Multimedia Development Life Cycle (MDLC) method was used to develop this application. The application testing in this research uses two types of testing namely Alpha and Beta testing with a black box scheme. Alpha testing results show that the app is compatible with Android OS 8.1 to 11.1 and smartphones with 5.45 to 6.4-inch displays. It requires at least 4GB to 8GB RAM According to the Beta Testing the application resulted in an outstanding 90.2% satisfaction rate. It can be concluded that the virtual 3D map application for Dean's Office Building A and Architecture Engineering Building B of the Faculty of Engineering at Lampung University functions effectively and is rated as "Very Good" based on the established criteria and index.
南榜大学每新学年都会为学生,特别是工程学院的新生举办例行活动,为新生介绍校园生活(PKKMB), PKKMB的主要议程之一是介绍土木工程的每栋建筑和公共设施,以及每栋建筑和里面的房间。新冠肺炎疫情的现状使得楠榜大学通过网络(在线)开展学习活动。建筑公共设施的面积和数量将成为新生和游客的一个问题,因为他们需要更长的时间来查找信息,探索和理解建筑环境的布局。为了解决这些问题,需要一种技术来满足信息、效率和向游客介绍建筑的新方法的要求。这些问题预计将通过为a楼(工程学院院长)和B楼(建筑工程)开发虚拟3D地图应用程序来解决。采用多媒体开发生命周期(MDLC)方法开发该应用程序。本研究的应用程序测试采用黑盒方案的Alpha测试和Beta测试两种类型的测试。Alpha测试结果显示,这款应用兼容安卓系统8.1到11.1,以及5.45到6.4英寸的智能手机。它至少需要4GB到8GB的内存,根据Beta测试,应用程序的满意度达到了90.2%。综上所述,楠榜大学工程学院院长办公大楼A和建筑工程大楼B的虚拟三维地图应用程序运行有效,根据既定的标准和指标,被评为“非常好”。

Viruses spread through email are often sent by irresponsible parties that aim to infect email users' servers. This background encouraged the author to analyze the application of DKIM, SPF, anti-spam, and anti-virus to avoid spam, viruses, and spoofing activities. The goal is for the server to prevent spam, spoofing, and viruses to ensure the security and convenience of email users and prevent the impact of losses caused by them. The design and analysis of DKIM, SPF, anti-spam, and anti-virus applications use the NDLC methodology. The process includes designing spam, spoofing, and virus filtering systems and performing installation and configuration simulations. The next stage is implementation, during which the previously developed system is tested on the spam filtering system, spoofing, and viruses. The last stage is the monitoring stage, where supervision is conducted on the approach to determine its success level. This study concludes that applying the DKIM protocol can prevent spoofing through private and public key-matching methods for authentication. Meanwhile, the application of the SPF protocol can prevent spoofing by authorizing the IP address of the sending server. Additionally, SpamAssassin, ClamAV and Amavisd-New can prevent spam and viruses from entering by checking email headers, bodies, and attachments.
通过电子邮件传播的病毒通常是由不负责任的人发送的,目的是感染电子邮件用户的服务器。在这种背景下,作者分析了DKIM、SPF、反垃圾邮件和反病毒的应用,以避免垃圾邮件、病毒和欺骗活动。目的是防止垃圾邮件、欺骗和病毒,确保电子邮件用户的安全性和便利性,防止由此造成的损失的影响。DKIM、SPF、反垃圾邮件和反病毒应用程序的设计和分析使用NDLC方法。该过程包括设计垃圾邮件、欺骗和病毒过滤系统,并执行安装和配置模拟。下一个阶段是实现,在此期间,前面开发的系统在垃圾邮件过滤系统,欺骗和病毒上进行测试。最后一个阶段是监测阶段,对方法进行监督,以确定其成功程度。本研究的结论是,应用DKIM协议可以防止通过私钥和公钥匹配方法进行身份验证的欺骗。同时,SPF协议的应用可以通过对发送服务器的IP地址进行授权来防止欺骗。此外,SpamAssassin、ClamAV和Amavisd-New可以通过检查邮件头、正文和附件来防止垃圾邮件和病毒进入。

This paper aims to describe the performance of the palm tree Coplanar Vivaldi Antenna Array (CVA) that was simulated from 0.25-6.25 GHz in terms of return loss and radiation pattern. Palm Tree Coplanar Vivaldi Antenna is available in four different configurations: single-element, two-element array, four-element array, and an eight-element array. We create a feeding network and radiator patch for two, four, and eight-array antennas. The simulation results demonstrate that the single-element antenna has the best return loss performance and can cover all frequency work from 0.25-6.25 GHz. In contrast, the antenna array can only cover multiband frequency. At 3 GHz, a single-element antenna has a directivity of 8.77 dBi, a sidelobe level of -2.2 dB, and a beamwidth of 63.70. In contrast, an antenna array of 8 elements has a directivity of 15.5 dBi, a sidelobe level of -12.6 dB, and a beamwidth of 80. Using the same substrate size, by configuring the Vivaldi Coplanar antenna to be an array at a frequency of 3 GHz, the 1×8 array antenna has a 6.73dBi improvement in directivity, a 10.4 dB boost in side lobe level, and a 55.70 enhanced in beamwidth performance compared to a single element. According to the simulation findings, the radiation pattern performance of the. Palm Tree CVA is greater than a single element in the same substrate size. Good directivity, SLL, and beamwidth performance make the proposed Palm Tree CVA array suitable for integration in telecommunication, radar, or cognitive radio applications.
本文旨在描述棕榈树共面维瓦尔第天线阵列(CVA)在0.25-6.25 GHz范围内的回波损耗和辐射方向图的模拟性能。棕榈树共面维瓦尔第天线有四种不同的配置:单元素、双元素阵列、四元素阵列和八元素阵列。我们为二阵,四阵和八阵天线创建一个馈电网络和散热器贴片。仿真结果表明,单单元天线具有最佳的回波损耗性能,可以覆盖0.25 ~ 6.25 GHz的所有频率工作。相比之下,天线阵列只能覆盖多频段频率。在3ghz时,单元件天线的指向性为8.77 dBi,旁瓣电平为-2.2 dB,波束宽度为63.70。相比之下,8元天线阵列的指向性为15.5 dBi,旁瓣电平为-12.6 dB,波束宽度为80。使用相同的衬底尺寸,通过将Vivaldi共面天线配置为频率为3 GHz的阵列,1×8阵列天线的指向性提高了6.73dBi,旁瓣电平提高了10.4 dB,波束宽度性能比单个元件提高了55.70。根据仿真结果,该天线的辐射方向图性能。棕榈树的CVA大于相同基质尺寸下的单个元素。良好的指向性、SLL和波束宽度性能使所提出的棕榈树CVA阵列适合集成在电信、雷达或认知无线电应用中。

Convolutional Neural Network (CNN) is very good at classifying images. To measure the best CNN architecture, a study must be done against real-case scenarios. Aglaonema, one of the plants with high similarity, is chosen as a test case to compare CNN architecture. In this study, a classification process was carried out on five classes of Aglaonema imagery by comparing five architectures from the Convolutional Neural Network (CNN) method: LeNet, AlexNet, VGG16, Inception V3, and ResNet50. The total dataset used is 500 image data, with the distribution of training data by 80% and test data by 20%. The segmentation process is performed using the Grabcut algorithm by separating the foreground and background. To build a model for CNN architecture using Google Colab and Google Drive storage. The results of the tests carried out on five classes of Aglaonema images obtained the best accuracy, precision, and recall results on the Inception V3 architecture with values of 92.8%, 93%, and 92.8%. The CNN architecture has the highest level of accuracy in classifying aglaonema plant types based on images. This study seeks to close research gaps, contribute to the field of research, and serve as a platform for primary prevention research.

The purpose of an educational website is to efficiently provide up-to-date services and resources to students, faculty, and staff. However, the needs of university students are not always prioritized throughout the design phase of websites; instead, technological considerations, organizational concerns, and commercial goals may all drive the process. When it comes to meeting the demands of the target audience, website designers often fall short. At the same time, visitors may encounter a wide variety of usability issues while visiting the sites. Thus, the purpose of this study is to examine the efficacy of different approaches to evaluating the usability of university websites from the viewpoint of their target audiences via user-based testing and questionnaire methods involving actual users. The outcomes, which are based on data from tests conducted in real time, outline the difficulties and advantages associated with each strategy. Both a user-based test and a questionnaire, which are both trustworthy evaluation methodologies, were used in the process of analyzing and evaluating the websites.
教育网站的目的是有效地为学生、教师和工作人员提供最新的服务和资源。然而,在整个网站设计阶段,大学生的需求并不总是优先考虑的;相反,技术考虑、组织关注和商业目标都可能驱动这个过程。当涉及到满足目标受众的需求时,网站设计师往往做不到。同时,访问者在访问网站时可能会遇到各种各样的可用性问题。因此,本研究的目的是通过基于用户的测试和涉及实际用户的问卷调查方法,从目标受众的角度来评估大学网站可用性的不同方法的有效性。结果基于实时测试的数据,概述了与每种策略相关的困难和优势。在分析和评价网站的过程中,使用了基于用户的测试和问卷调查这两种值得信赖的评价方法。

The exponential growth of deep learning networks has enabled us to handle difficult tasks, even in the complex field of medicine with small datasets. In the sphere of treatment, they are particularly significant. To identify brain tumors, this research examines how three deep learning networks are affected by conventional data augmentation methods, including MobileNetV2, VGG19, and DenseNet201. The findings showed that before and after utilizing approaches, picture augmentation schemes significantly affected the networks. The accuracy of MobileNetV2, which was originally 85.33%, was then enhanced to 96.88%. The accuracy of VGG19, which was 77.33%, was then enhanced to 95.31%, and DenseNet201, which was originally 82.66%, was then enhanced to 93.75%. The models' accuracy percentage engagement change is 13.53%, 23.25%, and 23.25%, respectively. Finally, the conclusion showed that applying data augmentation approaches improves performance, producing models far better than those trained from scratch.
深度学习网络的指数级增长使我们能够处理困难的任务,即使是在具有小数据集的复杂医学领域。在治疗领域,它们特别重要。为了识别脑肿瘤,本研究考察了三种深度学习网络如何受到传统数据增强方法的影响,包括MobileNetV2、VGG19和DenseNet201。结果表明,在使用方法之前和之后,图像增强方案对网络有显著影响。MobileNetV2的准确率由原来的85.33%提高到96.88%。VGG19的准确率由77.33%提高到95.31%,DenseNet201的准确率由82.66%提高到93.75%。模型的准确率变化百分比分别为13.53%、23.25%和23.25%。最后,结论表明,应用数据增强方法可以提高性能,生成的模型远远好于从头开始训练的模型。
