Health facilities such as hospitals produce medical waste and non-medical waste. Improper management of medical waste can cause the spread of infectious nature, especially during the Covid-19 pandemic. Therefore, management at the source, such as minimization and containment, is important and must be evaluated. This study evaluates hospital medical waste management based on minimization and containment efforts. This research was conducted by direct observation and literature review. The findings on minimization efforts are following regulations such as reducing the use of materials containing hazardous and toxic materials if there is a choice, avoiding accumulation and expiration of the procurement of chemicals and pharmaceuticals, and separating non-medical and medical waste according to the waste category. The container also meets the standard where the container is equipped with a cover and is made of puncture-resistant material. The containers are also equipped with bags and symbols according to the characteristics of the waste with internal transportation at least once a day or when the container has been filled. Garbage officers prepare medical waste handover documents. Transportation from the production source to the temporary shelter (TPS) uses a yellow trolley with a biohazard symbol, tightly closed with a predetermined route, and cleaning and disinfection are carried out on the trolleys that are used every day.

Monitoring information on tuition payments at an educational institution is an important part to support the activities in that agency. Information can be obtained from reporting and search results. To facilitate the presentation of information, it is necessary to have a system that manages these financial activities, therefore a web-based SPP payment information system is built that will be easily accessed from anywhere. In addition to management, this information system is designed so that students' parents can obtain information about bills and arrears. Telegram bots are an alternative for parents to get information about billing and payment information that can be accessed through the Telegram Messenger application so that it is more practical and interactive. The method used in developing this system is RAD (Rapid Application Development) and the framework used to build this information system is Laravel. The result of this research is that with this information system, the process of managing SPP payment data becomes easier and more effective, as well as accessing the information more practically and flexibly.

model (COCO) model top 5 93,3% dibandingkan 90% , 50% Abstract Nowadays, chicken meat has become a good source of animal protein for consumption and easy to obtain. However, in the process of obtaining it, fraudulent practices are often found, such as tiren chicken meat that is still being sold, or chicken meat that has been mixed with meat that is not worth selling. Therefore, we need a tool or application that is able to detect the quality of raw chicken meat. The purpose of this study is to create a tool that is useful in detecting the quality of raw chicken meat by utilizing image processing using the InceptionV3 model and named Quameaty. This tool was developed using the Python programming language. The InceptionV3 model is an excellent convolutional neural network training model and has been pre-trained on the Common Objects in Context (COCO) dataset of 328,000 images with 81 different classes. This model has a very high level of accuracy as a pre-trained model with a top 5 accuracy value of 93.3% and a relatively fast computation time when compared to its predecessor model. The resulting training model is embedded in an Android application which can be easily and tends to be flexible to be used in detecting the quality of raw chicken meat. The results of the study were divided into two classes, namely fresh and rotten, and showed that the prediction of the quality of raw chicken meat went well with the test metric values that had reached more than 90% at two threshold values, namely 50% and 75%.
摘要如今,鸡肉已成为一种易于获取且易于食用的良好动物蛋白来源。然而,在获取过程中,往往会发现欺诈行为,例如仍在销售的tiren鸡肉,或者鸡肉中掺入了不值得销售的肉类。因此,我们需要一种能够检测生鸡肉质量的工具或应用程序。本研究的目的是创建一种工具,可以通过使用InceptionV3模型利用图像处理来检测生鸡肉的质量,并命名为Quameaty。该工具是使用Python编程语言开发的。InceptionV3模型是一个优秀的卷积神经网络训练模型,并在包含328,000张81个不同类别的图像的COCO数据集上进行了预训练。该模型作为预训练模型具有非常高的准确率,前5个准确率值为93.3%,与之前的模型相比,计算时间也相对较快。由此产生的训练模型被嵌入到一个Android应用程序中,该应用程序可以很容易地并且倾向于灵活地用于检测生鸡肉的质量。研究结果分为新鲜和腐烂两类,结果表明,在50%和75%两个阈值下,对生鸡肉质量的预测效果良好,测试度量值均达到90%以上。

In a university the role of the chancellor is very important. Currently, the Telkom Purwokerto Institute of Technology (ITTP) is in the election stage for potential chancellor candidates because the previous chancellor’s term of office has ended, namely the 2017 to 2021 period. In electing the chancellor at ITTP, there are several obstacles faced, such as: data security aspects that are still not maintained, updates data or documents required for chancellor candidates and limited access to information during the offline pandemic period. In order to protect data from outside parties and to document the files of the prospective chancellor candidates in real time, a system is needed to facilitate the process of electing the chancellor. This study aims to develop an online rector election system. System development is carried out using the Scrum method. Every job is completed in a short period of time. Each sprint is a work from a backlog according to the required needs. The application of the Scrum approach is very effective in developing this chancellor election application. The results obtained from the application of Scrum are an online chancellor election system that can be developed according to the product backlog determined by the product owner.
在一所大学里,校长的角色是非常重要的。目前,Telkom purokerto理工学院(ITTP)正处于潜在校长候选人的选举阶段,因为上一任校长的任期已经结束,即2017年至2021年期间。在ITTP的校长选举中,面临着一些障碍,例如:数据安全方面仍然没有得到维护,校长候选人所需的更新数据或文件,以及在离线大流行期间对信息的访问有限。为了保护外界的数据,并实时记录未来校长候选人的档案,需要一个促进校长选举过程的系统。本研究旨在开发一套网上选举系统。系统开发使用Scrum方法进行。每一项工作都是在短时间内完成的。每个sprint都是根据所需需求从积压工作中提取的一项工作。在开发这个校长选举应用程序时,Scrum方法的应用非常有效。从Scrum应用中获得的结果是一个在线校长选举系统,可以根据产品所有者确定的产品待办事项来开发。

Routing Border Gateway Protocol (BGP) which functions as the backbone of the internet network by default does not have a strong security mechanism. There are often cases where BGP routing running on the internet experiences hijacking of its network route or misconfiguration either intentionally or unintentionally on BGP route information which causes the internet network to fail or be inaccessible. The implementation of BGP with Resource Public Key Infrastructure (RPKI) will allow a network to filter existing routes so that its existence can make internet networks that use BGP directed to only valid routes and avoid piracy of invalid route information. This study seeks to measure the performance of the BGP RPKI at PT Time Excelindo. Implementation of BGP RPKI to increase CPU and device memory usage by 3.6% and 0.75% and reduce router input power in receiving incoming prefix information by 1.15%. In addition, in terms of network quality, after implementing BGP RPKI, the download and upload values decreased by 0.11 Mbps and 0.02 Mbps plus an increase in the latency value of 0.13 ms.
BGP (Routing Border Gateway Protocol,路由边界网关协议)作为internet网络的骨干网,在缺省情况下没有很强的安全机制。在internet上运行的BGP路由经常会遇到网络路由被劫持或有意无意地对BGP路由信息配置错误,从而导致internet网络故障或不可访问的情况。通过资源公钥基础设施(Resource Public Key Infrastructure, RPKI)实现BGP,可以对现有的路由进行过滤,从而使使用BGP的internet网络只定向到有效的路由,避免无效路由信息被盗版。本研究旨在衡量BGP RPKI在PT时间Excelindo的性能。实现BGP RPKI,使CPU和设备内存利用率分别提高3.6%和0.75%,使路由器接收传入前缀信息的输入功率降低1.15%。此外,在网络质量方面,实现BGP RPKI后,下载和上传值分别下降了0.11 Mbps和0.02 Mbps,延迟值增加了0.13 ms。

People who live in rural areas still often face problems or obstacles in accessing information via the internet. The common problem they face is poor Internet Service Provider (ISP) service provider connectivity, such as network drops and slowness. The purpose of this study is to build a prototype internet access network for people living in rural areas using two microwave radio links based on Ethernet over Plesiochronous Digital Hierarchy (PDH) technology as a backhaul connected to an ISP. The method used to integrate the two radio links is to use the load balancing method which is a feature found on the Mikrotik router that functions to combine internet traffic from both ISPs simultaneously and channel it to a local network provided for public internet access. Apart from that, the load balancing router also functions as a protection system where if one of the traffic drops which may be caused by an outage (dead) radio link or a service from an ISP that dies, it is hoped that the traffic will still be there so that users can still get internet service. Based on the results of testing and measurements with a traffic data rate of 1.3 Mbps, it can be concluded that this research was successful in building a prototype of a reliable and stable internet access network for the public to obtain information.
生活在农村地区的人们在通过互联网获取信息方面仍然经常面临问题或障碍。他们面临的常见问题是互联网服务提供商(ISP)服务提供商的连接性差,例如网络掉线和网速慢。本研究的目的是为居住在农村地区的人们建立一个互联网接入网的原型,使用基于以太网的两个微波无线电链路,通过PDH技术作为回程连接到ISP。用于集成两个无线电链路的方法是使用负载平衡方法,这是microrotik路由器上的一个功能,它可以同时将来自两个isp的互联网流量组合在一起,并将其引导到提供公共互联网访问的本地网络。除此之外,负载平衡路由器还可以作为一个保护系统,如果其中一个流量下降,可能是由于中断(死)的无线电链路或来自ISP的服务死亡,希望流量仍然存在,以便用户仍然可以获得互联网服务。基于流量数据速率为1.3 Mbps的测试和测量结果,可以得出结论,本研究成功构建了一个可靠、稳定的互联网接入网原型,供公众获取信息。

The development of telecommunication technology in the field of cellular networks has now entered the 5th generation or 5G. This 5G application has more capable performance than the previous generation so that antenna specifications with wide bandwidth and large gain are needed. The antenna that can be used is microstrip antenna. Microstrip antennas have the advantages of having a light mass, practical, and easy to fabricate. However, there are disadvantages in the parameters obtained, such as narrow bandwidth and small gain. To overcome these disadvantages, you can use the air gap method, where the method can be used to widen bandwidth and increase gain. In this study, optimization has been successfully carried out on the microstrip array antenna using the airgap method at a frequency of 3.5 GHz. The results of the optimization during simulation obtained an increase in bandwidth of 54.28% and an increase in gain of 32.86%. For the realization results, a bandwidth of 280 MHz, and a gain of 9.3 dB were obtained. The substrate used in this antenna is FR4 which has a dielectric constant of 4.4, thickness of 1.6 mm, and loss tangent of 0.019.
在蜂窝网络领域,电信技术的发展已经进入了第5代,即5G。这种5G应用比上一代具有更强大的性能,因此需要具有宽带宽和大增益的天线规格。可以使用的天线是微带天线。微带天线具有质量轻、实用、易于制作等优点。但是,所获得的参数存在带宽窄、增益小等缺点。为了克服这些缺点,可以使用气隙方法,这种方法可以用来扩大带宽和增加增益。在本研究中,利用气隙法在3.5 GHz频率下成功地对微带阵列天线进行了优化。仿真结果表明,优化后的带宽提高54.28%,增益提高32.86%。实现结果表明,该系统的带宽为280mhz,增益为9.3 dB。该天线采用的衬底为FR4,其介电常数为4.4,厚度为1.6 mm,损耗正切为0.019。

A Field Programmable Gate Array (FPGA) is a semiconductor component based on a matrix of user-configurable logic blocks connected through programmable interconnects. FPGA can be programmed according to the application or function required by the user. To support science in the field of electronic engineering, it is necessary to have learning media regarding the basic use and application of FPGA. Therefore, in this study, an ON-OFF control simulator module was made using an FPGA. There are two approaches used in building ON-OFF control, namely pure ON-OFF and ON-OFF using delay time, where this delay time is defined using counter logic. All control algorithm designs use the VHSIC Hardware Description Language (VHDL) description. The implementation results show that the response can be in accordance with the desired conditions. For the ON-OFF condition with counter logic, the DC motor can be ON for 5 seconds then OFF automatically according to the desired behaviour.
现场可编程门阵列(FPGA)是基于通过可编程互连连接的用户可配置逻辑块矩阵的半导体组件。FPGA可以根据用户需要的应用或功能进行编程。为了支持电子工程领域的科学研究,需要有关于FPGA的基本使用和应用的学习媒体。因此,在本研究中,使用FPGA制作了一个开关控制模拟器模块。有两种方法用于构建ON-OFF控制,即纯ON-OFF和使用延迟时间的ON-OFF,其中延迟时间使用计数器逻辑定义。所有控制算法设计都使用VHSIC硬件描述语言(VHDL)描述。实现结果表明,响应符合预期条件。对于具有计数器逻辑的开关条件,直流电机可以根据所需的行为自动打开5秒然后关闭。
