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%.","PeriodicalId":344916,"journal":{"name":"Jurnal Jartel","volume":"57 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127400230","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}

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%.","PeriodicalId":344916,"journal":{"name":"Jurnal Jartel","volume":"161 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":"123611837","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}

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%.

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.","PeriodicalId":344916,"journal":{"name":"Jurnal Jartel","volume":"33 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114112447","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}

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.","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}

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.
