Kegunaan filter digital adalah untuk menyaring frekuensi serta memodifikasi spektrum frekuensi pada suatu sinyal sehingga diperoleh tujuan yang diinginkan. Tujuan dari filter adalah sebagai rangkaian yang melewatkan suatu pita frekuensi tertentu yang diinginkan dan meredam pita frekuensi lainnya. Adapun metode yang digunakan dalam merancang filter FIR adalah menggunakan metode windowing. Ada beberapa teknik yang terdapat dalam metode windowing, yaitu rectangular, hamming, hanning, dan kaiser. Untuk sistem kerja windowing sangat bergantung pada jenis window yang digunakan, maka dari itu terdapat perbandingan diantara keempatnya. Pada penelitian ini akan dikembangkan dengan merancang filter digital FIR yang diimplementasikan pada perangkat raspberry pi yang diharapkan dapat terintegrasi dengan baik menggunakan matlab simulink. Maka dibuat penelitian yang mengangkat masalah pada bagaimana cara pengolahan sinyal digital untuk mengaplikasikan filter FIR menggunakan metode windowing yang disimulasi menggunakan program matlab dan diimplementasikan pada raspberry pi. Dari hasil pengujian dapat diketahui bahwa Raspberry pi dapat terintegrasi dengan baik menggunakan matlab Simulink. Semakin besar ripple, atenuasi stopband, dan lebar bandwidth pada hasil respon frekuensi output sinyal mempengaruhi orde yang dihasilkan, yaitu semakin kecil.","PeriodicalId":367075,"journal":{"name":"Jurnal Jartel: Jurnal Jaringan Telekomunikasi","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129512997","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}

For tenants, you can make payments only when meeting with the boarding house owner/manager. In practice, boarding house owners are not always in the boarding house so there is a difficulty in monitoring the boarding payments for each room. The purpose of this final project is to make a tool to be able to monitor and manage boarding through the android smartphone media. In this system, boarding house owners can find out the payment status of each room and tenants can also find out the remaining rental time. This system is also installed with a doorlock solenoid which can be controlled by the boarding house owner via the Android application to open and close the boarding house door if the tenant has/has not made a payment. The process of sending data from the device installed in the room to the Android smartphone using an intermediary NodeMcu and sending data to Firebase so that the status can be monitored in realtime. In each room there is also a notification system in the form of an LED light. The LED light will give a warning about the remaining time of the boarding house rental. The conclusion in this final project, the application can perform monitoring realtime and tenants can control the solenoid with an average delay of 1m 68s.

Attendance is a data collection activity to determine the number of employee attendance. The employee attendance system at the ngajum sub-district office uses fingerprint technology (Fingerprint). This system is indeed very easy and efficient, but in the sub-district office there are several employees who have difficulty carrying out the fingerprint attendance process because the fingerprints are peeled off or have certain diseases make fingerprints smooth. So that the fingerprint attendance (Fingerprint) at the sub-district office is not used and returns to the manual system. The purpose of this research is to design an employee attendance information system to enter and leave by utilizing the National Identity Card or KTP. For checking IDKTP uses the NFC Reader PN532 which is connected to Arduino Uno as a microcontroller, Raspberry pi as a web server, webcam, LCD display, and buzzer as a sign of success in making attendance. Based on the test results it can be concluded, the NFC reader used can read ID KTP in position vertical and horizontal with a distance of less than 16 mm. When there is a mica barrier and a glass barrier the maximum reading distance is less than 14 mm while the plate and aluminum foil barrier cannot be read. The existence of a barrier makes the distance to read the KTP will be reduced.","PeriodicalId":367075,"journal":{"name":"Jurnal Jartel: Jurnal Jaringan Telekomunikasi","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124546426","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}

Charging using a cable certainly limits the use of the smartphone when it is charging. Smartphone users can not be far from the electric socket which of course is troublesome if this happens in the middle of a room that has a few electrical sockets. To solve this problem, now many wireless charging smartphones or smartphones have been developed wireless charger. Behind the benefits obtained from a wireless charger, it also has disadvantages, namely the transmission distance is short, even there is no distance and the transmitted power is unstable. Wireless chargers are based on the principle of magnetic induction in which electricity is transferred between two objects through a coil. Wireless charger consists of the primary coil as a charger (usually in the form of a thin board or cylinder), and the secondary coil is located on the back of the cellphone. Based on the results, the output power is obtained. The largest wireless charger is 0.027W with a coil diameter of 8cm in all the number of primary coils, namely 40 turns, 50 turns, and 60 turns at a primary and secondary coil distance of 0cm to 1cm.

This process is supported by telecommunications devices, such as telephones. The use of telephones in agency generally uses PBX system because it has advantages in cost, flexibility, and communication security. With the development of the era, the technology of PBX devices must be updated, but there is a solution besides updating the device, which is to add modules or devices while still using the existing PBX. This research discuss the analysis regarding the comparison of service quality of the Internet Telephony Gateway with the FXS module. The system uses the network as a medium for exchanging communication data, so all communication devices used must be connected to the local network. Communication between devices can occur when each communication device is registered on the PBX server. Testing the quality service is influenced by amount of jitter, packet loss, and throughput. From the test results, it can be concluded that the number of active users simultaneously affects the value of jitter, packet loss, and throughput. When 8 ports of the FXS module are used simultaneously, the average jitter value reaches 27,625 ms, the packet loss value is 156,875%, and the throughput is 66,625 kb/s. Meanwhile, the TA1600 was able to serve 16 users with an average jitter value of 57,875 ms, packet loss reaching 227.31%, and a throughput of 26.31 kb/s. These results were obtained through the Zoiper application statistical data.","PeriodicalId":367075,"journal":{"name":"Jurnal Jartel: Jurnal Jaringan Telekomunikasi","volume":"281 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114172308","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}
