Administration is the activity of systematically managing and recording data information to provide various information and also make it easier to retrieve it either partially or completely. The administration of mailing at SMK Negeri 1 Glagah is still conventional by recording incoming and outgoing mail using a book and storing the mail in an uncertain places. Some of the problems that can be solved with information technology, one of which is the storage of incoming and outgoing mail at SMK Negeri 1 Glagah. With a mail administration application that uses the CodeIgniter Framework and MySQL database, teachers who being admins or operators can directly enter incoming and outgoing mail data in the application, and they can directly distribute the mail to the receiver person through the application. Teacher who receive the mail will get a notification on the application if there is a new mail coming in. With the Mail Administration Application, staff and school principals can find out the existing mail data easily and computerized with accurate and archived data. The results of the questionnaire recapitulation can be concluded that the overall application quality level is in Good criteria, with a percentage of 84.33%.
管理是系统地管理和记录数据信息，以提供各种信息，并使其更容易部分或全部检索的活动。SMK Negeri 1 Glagah的邮寄管理仍然是传统的，用一本书记录进出的邮件，并将邮件存放在不确定的地方。有些问题可以用信息技术来解决，其中之一就是在SMK Negeri 1 Glagah存储收发邮件。通过使用CodeIgniter框架和MySQL数据库的邮件管理应用程序，作为管理员或操作人员的教师可以直接在应用程序中输入收发邮件的数据，并通过应用程序直接将邮件分发给收件人。如果收到新邮件，收到邮件的教师将收到申请通知。透过“邮件管理应用程式”，教职员及校长可轻松查阅现有的邮件资料，并以准确及存档的资料电脑化。问卷重述结果显示，整体应用质量水平为良好，占84.33%。

In this technology age, people's need for communication systems is growing. In various places and conditions, communication must be maintained to meet various needs. One of the solutions required in these circumstances is an optical fiber communication system. Fiber optic cable is a light-based data transmission technique. The advantages of optical transmission include the fact that the light spectrum does not spread like radio frequencies, making it impossible to intercept, the fact that it propagates at a very high speed, allowing it to go very large distances, and the ease with which it may be installed. To tackle this problem, we proposed to innovate by realizing and developing a two-way voice and text communication system using fiber optic cable media. The voice and text communication system created and deployed in this study is based on an Android application. This communication system does not require a server and internet network. Only Android smartphones, access points, fiber media converters, and fiber optic cables are required. The greatest throughput value measured by the system is 2708 bytes/second, while the lowest is 1020 bytes/second. The longest delay is 2.314 seconds, while the shortest is 1.99 seconds. In terms of packet loss, the value is 0%.

IP Phone merupakan salah perangkat pada Voice over Internet Protocol (VoIP) yang dapat menyalurkan suara menggunakan IP. Berbagai tipe IP Phone bermunculan dengan harga dan fitur yang bervariasi, sehingga menimbulkan pertanyaan terkait bagaimana perbandingan kualitas suara pada IP Phone yang dihadirkan oleh berbagai tipe tersebut, mengingat kualitas suara dalam telekomunikasi sangat penting agar tidak menimbulkan kesalahfahaman saat telekomunikasi berlangsung. Terdapat dua tipe IP Phone pada sistem yang sudah diregistrasikan dengan server sehingga dapat melakukan panggilan dengan range frekuensi 300Hz s/d 3400Hz, kemudian dari komunikasi antar IP Phone terdapat bentuk gelombang sinyal informasi input dan output, respon amplitudo suara terhadap perubahan frekuensi suara serta nilai delay dari pergeseran fasa menggunakan alat ukur Tranmission Test Set dan Oscilloscope yang digunakan untuk mengetahui karakter kualitas suara dalam komunikasi antar IP Phone sesuai hasil uji parameter. Hasil pengujian sitem dapat disimpulkan bahwa bentuk gelombang sinyal informasi input dan output pada frekuensi suara memiliki bentuk gelombang sinus, namun gelombang output pada IP Phone tipe A frekuensi 300Hz s/d 1100Hz dan IP Phone tipe B frekuensi 300Hz s/d 1300Hz mengalami distorsi, selanjutnya dari hasil nilai Peak to Peak gelombang diketahui adanya penguatan tegangan yaitu semakin besar nilai frekuensi pada input maka akan semakin kecil nilai penguatan tegangan yang dihasilkan. Nilai respon amplitudo terhadap perubahan frekuensi suara dengan nilai amplitudo input -23.5 dBm pada kedua IP Phone memiliki penguatan daya yang semakin kecil ketika nilai frekuensi suara semakin tinggi. Nilai delay yang didapatkan dari pergeseran gelombang input dan output antar IP Phone yaitu kurang dari 150 ms.
IP电话是互联网协议中一个可以通过IP传输声音的设备。各种类型的IP电话的价格和功能各不相同，这引发了一个相关的问题，即如何比较这些类型的IP电话的音质，因为在电信中，声音的质量是至关重要的，这样就不会在电信期间造成错误。在一个系统中有两种类型的IP电话，它可以在服务器上重建，使其能够进行一个范围为300Hz s/d 3400Hz的通话，然后从IP单元之间的通信中包含输入和输出信息的波，声音振幅对声音频率的变化和延迟值的反应使用传测器和Oscilloscope，用于根据参数的测试结果确定IP之间通信中的声音质量特征。系统测试结果可以得出结论,波形信号信息输入和输出声音频率的正弦波成型,但美国波浪型IP电话的输出频率300Hz - d 1100Hz和IP电话的B型300Hz频率s - d 1300Hz失真,接下来的峰的峰知道的深化波电压值就是输入频率值就越大价值越小电压产生的强化。声音频率变化的振幅响应值与输入振幅-23.5 dBm的两个IP手机都有一个更小的增量，当声音频率值增加时，它的功率更小。IP之间输入和输出波的延迟值小于150 ms。

The pandemic period caused by the coronavirus disease causes restrictions on the number of users in a room to minimize the spread, for example, libraries. The library is a room area that can cause virus transmission when crowds of visitors. A system is needed to provide information regarding the number of library visitors. Utilizing a network (wifi transmitter) available in the library can provide information on the number of visitors based on the number of network users in a room. Utilization of the network (wifi transmitter) can be in the form of a positioning system by utilizing the wifi signal beam received by the user in RSSI (Received Signal Strength Indicator). To calculate the estimated user position, a trilateration method is used based on the placement of three wifi transmitters. The library visitor positioning system consists of users as wifi transmitter users and admins. At the X-coordinate, the measuring point with a low deviation of the measurement value is indicated by points C and E with a value of 0.1. The large deviation of the measurement value is indicated by the P point of 4.5. At the Y coordinate, point O has a low deviation value of 1.25, and the largest deviation value is at point M of 5.6. The accuracy of the X coordinate shows a value of 97.647% and at the Y coordinate of 96.57%. Both coordinates have good accuracy for the points used as position measurements.
在新冠肺炎大流行期间，为了最大限度地减少传播，图书馆等单位对房间内的人数进行了限制。图书馆是一个房间区域，当游客拥挤时可能导致病毒传播。需要一个系统来提供有关图书馆访客人数的信息。利用图书馆内可用的网络(wifi发射机)，可以根据房间内网络用户的数量提供访客数量信息。利用网络(wifi发射机)，利用用户在RSSI (received signal Strength Indicator，接收信号强度指标)中接收到的wifi信号波束，形成定位系统。为了计算估计的用户位置，使用了基于三个wifi发射器位置的三边测量方法。图书馆访客定位系统由wifi发射机用户和管理员用户组成。在x坐标处，测量值偏差较小的测点用C点和E点表示，其值为0.1。测量值偏差较大，以P点为4.5表示。在Y坐标处，O点偏差值较小，为1.25,M点偏差值最大，为5.6。X坐标的精度为97.647%，Y坐标的精度为96.57%。这两个坐标对于用于位置测量的点都有很好的精度。

Generally, height and weight measurements are carried out separately as well as to determine the Body Mass Index must be calculated manually using specific formulas that not everyone understands, so it is difficult to know whether the body has reached a normal number or not. This study will provide suggested solutions to support the body to be healthy in measuring devices and android applications, for height measurement using ultrasonic sensors, weight using loadcell sensors and NodeMCU ESP8266 as data processors. The results of measuring height and weight appear on an LCD, the results of Body Mass Index (BMI) and the recommended solutions to meet standard body numbers in calculating BMI appear on the android application. Based on the results of the tests carried out, it is known that designing a measuring instrument with NodeMCU ESP8266 based on Android has been successfully carried out. The measuring instrument by implementing the Ultrasonic Sensor HC-SR04 as a height measurement can perform a success percentage of 96.95% and Loadcell Sensor as a weight measurement can perform the percentage of success is 98.97%, while in measuring Body Mass Index (BMI) can do a success percentage of 90.84%, the measuring instrument can also emit sound in the form of body condition in accordance with the measurement results obtained by the microcontroller with a success percentage of the sound output of 100% but has an average percentage of voice output delay variations of 2.1 seconds.

A kiosk / traditional minimarket is a small shop that generally sells goods like a modern minimarket. During this pandemic, it is recommended to pay for an item without contact (online) to break the chain of the Covid-19 virus. Therefore, an Android-based smartphone is very useful for making payments for an item online. Most people desire to have an item they want even though the price offered is sometimes quite expensive. However, some buyers want to get the goods as soon as possible and for payment to wait for a certain period according to their ability. This is detrimental to the kiosk owners because they do not get income from selling their goods. This reminder makes it easier for sellers to collect bills automatically without waiting for buyers to shop again at the same kiosk. Besides that, there is a limit for each buyer, which is useful for kiosk owners, so they do not lose money. This research needs to have a communication system that can make it easier for kiosk owners to collect bills from their customers without waiting for the customer to come again to shop at the same kiosk. In other words, the kiosk owner has certainty from the customer according to the agreed payment due date.

In other words, the kiosk owner has certainty from the customer according to the agreed payment due date.","PeriodicalId":344916,"journal":{"name":"Jurnal Jartel","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129133690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berenang merupakan kegiatan yang digemari masyarakat. Namun tanpa disadari, beberapa kolam renang memiki kualitas air yang tidak cukup bagus sehingga menjadi media penularan berbagai penyakit dalam air. Pengawasan kualitas air kolam renang merupakan upaya sanitasi yaitu dengan memberikan cairan kaporit untuk mereduksi zat organik dan sebagai desinfeksi terhadap mikroorganisme. Dengan adanya hal tersebut penulis melakukan penelitian mengenai sistem telemonitoring kekeruhan dan pH air terhadap pengurasan serta pemberian kaporit otomatis dalam kolam renang berbasis smartphone. Sistem diaplikasikan pada miniature kolam renang yang terdiri dari empat sensor yaitu sensor pH, sensor turbidity, sensor ultrasonik, sensor waterflow, keempat sensor akan mengirimkan data ke ESP32 untuk diproses sesuai sistem yang dibuat. Setelah ESP32 selesai melakukan pemrosesan kemudian dikirimkan pada firebase dan aplikasi pada smartphone untuk mempermudah monitoring dan kontroling air. Hasil pengujian dapat disimpulkan bahwa sistem dirancang menggunakan ESP32 sebagai mikrokontroler akan memproses hasil data dari sensor pH, sensor turbidity, sensor waterflow dan sensor ultrasonik. Kemudian hasil data pH memiliki nilai pH paling tinggi yaitu 7,9 dan terendah 6,9. Selanjutnya hasil data sensor turbidity memilki nilai 0 NTU dengan ADC tertinggi 3827. Pengurasan secara otomatis dibagi menjadi 2, yaitu sebagai monitoring dan kontroling. Selanjutnya untuk kualitas jaringan WiFi yang diuji menggunakan Wireshark ketika melakukan proses pengiriman data dari segi delay memiliki nilai rata-rata 0.188389435, packet loss 1.178 dan throughput 7428 Kb/s.
游泳是一种受欢迎的活动。然而，不知不觉中，一些游泳池的水质不够好，不足以成为水中疾病的传播媒介。对游泳池水质的监督是一项卫生工作，即为有机溶剂和对微生物进行消毒。考虑到这一点，作者正在对智能手机泳池自动排泄和水pH值系统进行研究。系统应用于四种由pH传感器、turbidity传感器、超声波传感器、水流传感器组成的微型池传感器，四种传感器将向ESP32发送数据，根据创建的系统进行处理。一旦ESP32完成处理，然后将其发送到firebase和智能手机上的应用程序，使水监测和控制更容易。测试结果可以得出结论，该系统的设计目的是使用ESP32作为一个微控制器来处理来自pH传感器、turbidity传感器、waterflow传感器和超声波传感器的数据结果。pH值最高的是7.9和6.9。此外，turbidity传感器的数据显示，ADC最高3827的值为0 NTU。消解被自动分为2，即监督和控制。此外，使用Wireshark进行数据传输测试的WiFi网络质量均为0.188389435,packet loss 1178和throuput 7428 Kb/s。

This paper introduces a millimetre-wave antenna design for 5G application using an alternative substrate called Kevlar-Alumina Composite. Kevlar-Alumina Composite had been researched and measured comprehensively by Indonesian Institute of Science (LIPI) Bandung showing dielectric value of 9.2. The application of the antenna geometry is based on Vivaldi Coplanar antenna with L shaped feeding on the ground plane. Vivaldi Antenna is chosen as it has a relatively small size with various structures. An antenna of 3.75 GHz for 5G application using Kevlar-Alumina Composite is proposed. The simulated results of single-element 5G antenna have return loss value of -21.949 dB, 1.173 VSWR, directive radiation pattern at E-Plane and H-plane, and surface current. The use of the Kevlar-Alumina Composite performed good results.
