Abstract

VSAT (Very Small Aparture Terminal) or micro earth station is the telecommunications used data communications network between computer through satellite constructively by controller station with antenna; diameter of 1,8 m and also the form small and easyly installation at every user location. This research evaluate usage of network VSAT so that inferential in the end how far usage ofd data communications network evaluated from transmission media VSAT used and from this research can give the picture situation of the network use VSAT so that can give the data support for pengatran system performance and planning of network capacities in future. This research use the reference - the reference that relevance with VSAT and collect data of companies/ related/relevant institution as reference in analysing the data (throughput and delay) so that yield the information sistimatis concerning the network performance handal. This research result throughput VSAT canal is 0,32 or 32% and delay is 0,318 second for successful package ( free collision) and also to once remanding have delay 1,838 second.

Abstract

Compensation is an activity carried out by students outside class hours as a sanction for the student's absence from attending scheduled lectures. In this era, information is really needed, especially information on compensation in lectures. Initially compensation on digital telecommunications networks was still done manually or by coming directly to the admin to ask about compensation. But after this system is created, it will improve the compensation system on digital telecommunications networks. Students only need to access the website and no longer need to come to campus to find out information about compensation. The website has been designed in such a way to make things easier for students. This system is very useful for students because all compensation matters can be done via the website so it will be more effective for students. The problem with the Digital Telecommunication Network Study Program is that 84% of students have not compensated and only 16% of students have compensated. Based on these problems, development was carried out in the form of designing a web-based compensation information and registration system using biometric fingerprints for sending compensation agreements using a telegram bot. The information system used is a series of biometric systems with fingerprint sensor devices with FPM10A module, Telegram Bot, Arduino and ESP32 features and produces a system prototype that can provide information about compensation and compensation registration to polynema students so that it can make things easier for students of the Digital Telecommunication Network Study Program Malang State Polytechnic in paying compensation

Abstract

Single phase induction motors are one of the most frequently used types of motors because of their economical, sturdy, simple and easy maintenance advantages. One application is for electric vehicles. When single phase induction motors are applied to electric vehicles there are problems related to torque regulation based on vehicle operating conditions where when operating on light road conditions the torque produced by the motor remains high. In this research, a single-phase induction motor was made to have the same proportion of torque produced by the main coil and auxiliary coil or a 1kW 1000 rpm symmetrical two-phase induction motor. The type of winding applied to the stator is divided screws with the main and auxiliary coils each occupying 18 stator slots, 45 conductors per slots,, with a conductor diameter of 1.2 mm. As a phase shifter at start and operation so that they differ by 90°, a capacitance of 505.51 µF is used. As a result of the winding modification, the induction motor parameter values ​​for each stator winding are the same. So the starting torque of the main and auxiliary coils is 3.89 Nm and 3.88 Nm respectively and the nominal torque produced by the main and auxiliary coils is 4.28 Nm and 4.29 Nm respectively.

Abstract

Media pembelajaran merupakan salah satu aspek yang menetukan kualitas pendidikan. Bagi daerah perkotaan, media pembelajaran digital mudah dijangkau dan beragam. Namun, bagi daerah yang masih terbelakang, hal ini cukup sulit untuk diakses. Metode pembelajaran hibrid dapat menjadi salah satu pilihan bagi sekolah saat ini dikarenakan dapat memberikan pengaruh positif yaitu siswa dapat terlatih belajar secara mandiri namun juga tetap mendapat pelajaran secara luring. Namun, untuk daerah yang belum terjangkau internet, pembelajaran hibrid masih terbilang sulit untuk diterapkan, maka dari itu diperlukan jaringan intranet yang dapat diakses siswa maupun guru tanpa adanya jaringan internet. Tujuan dari penelitian ini yaitu membuat server pembelajaran dengan memanfaatkan sistem Voice over Internet Protocol (VoIP) berbasis Web Server. Konten yang disajikan dalam website ini dikemas dalam bentuk video dan latihan soal, serta antar siswa dengan guru dapat berkomunikasi menggunakan fitur komentar yang disediakan. Perancangan sistem menggunakan metode penelitian pengembangan dan pembuatan. Pengujian performa layanan dilaksanakan dengan menguji Quality of Service (QoS) meliputi Delay, Jitter, Throughput, dan Packet Loss. Analisa performa jaringan ini bertujuan untuk mengetahui kemampuan website dalam mengirim dan menerima data kepada pengguna saat diakses. ABSTRACT Learning media is one aspect that determines the quality of education. For urban areas, digital learning media is easy to reach and diverse. However, for underdeveloped areas, this is quite difficult to access. The hybrid learning method can be an option for schools at this time because it can have a positive influence, namely that students can be trained to learn independently but also still receive lessons offline. However, for areas that do not have internet access, hybrid learning is still difficult to implement, therefore an intranet network is needed that can be accessed by students and teachers without an internet network. The aim of this research is to create a learning server by utilizing a Web Server-based Voice over Internet Protocol (VoIP) system. The content presented on this website is packaged in the form of videos and practice questions, and students and teachers can communicate using the comments feature provided. System design uses development and manufacturing research methods. Service performance testing is carried out by testing Quality of Service (QoS) including Delay, Jitter, Throughput and Packet Loss. This network performance analysis aims to determine the website's ability to send and receive data to users when accessed.

Abstract

Rural development has undergone significant changes since the digitization of Information and Communication Technology (ICT). Hybrid media technology has proven to make it easier for innovative villages to build networks and empower their communities to narrow the ICT gap, one of which is through community service. This community service is an effort of Gorontalo State University so that the Tridarma of Higher Education is implemented to contribute science and technology to the community. This Community Service was carried out in Tamboo Village, Bone Pantai District, Bone Bolango Regency. The purpose of this Community Service was to provide counseling on how to condition the beginning of a village so that it becomes a digital village. The expected output targets from this activity are: 1) The officials and community in Tamboo Village have knowledge of the importance of the village internet and how to manage infrastructure related to the village internet. 2) Village officials or village internet managers can have the ability to use internet facilities, which can then be developed to create village websites for digitization: village profile data, population data, village resource and potential data and other activities that can be digitized for work effectiveness and efficiency.

Abstract

Desa Kemantren Jabung, yang mayoritas penduduknya merupakan peternak sapi perah, saat ini menghadapi tantangan dalam pemrosesan susu sapi. Sebagian besar warga masih menggunakan metode manual untuk memerah susu sapi, dan hasilnya disetorkan ke pengepul susu sapi di CV Amanah. Di pengepul ini, mesin penyimpanan susu memerlukan sumber daya listrik sebesar 5000 watt dari PLN. Keadaan ini mengakibatkan fluktuasi kualitas susu dan menuntut daya listrik yang cukup besar. Untuk mengatasi masalah ini, penggunaan Solar PV system sebagai pasokan daya untuk mengisi beterai mesin portable perah sapi dapat menjadi solusi yang efektif. Pendekatan ini tidak hanya dapat meningkatkan konsistensi kualitas susu, tetapi juga dapat mengurangi beban biaya listrik yang harus ditanggung oleh para peternak. Dengan demikian, penerapan sistem energi terbarukan ini diharapkan dapat mempermudah proses panen susu ternak dan meningkatkan efisiensi secara keseluruhan.
