Abstract

Nowadays the education sector has changed due to the covid-19 pandemic, but the government has tried to reduce this impact by providing WiFi in some areas. This article seeks to compare the quality of the internet network in an area that offers WiFi to the surrounding population, particularly students as a support for DL (Distance Learning), simulation, and the ideal scenario. In order to determine the quality of a network, one needs to consider the QoS (Quality of Service) metrics, which include packet loss, throughput, latency, and jitter. Using Wireshark (network analyzer software), this research collects data on the item to be investigated; the obtained data will be analyzed to determine the QoS of the WiFi service under investigation. In addition, this research will do network modeling and simulation using the opnet modeler (network simulation software), which will be utilized to compare the observed items. While video conferencing was used to analyze latency and jitter during a 60-minute sample length assessment, 500 MB of data was used to evaluate throughput and packet loss. Keywords: Quality of Service, packet loss, throughput, delay, jitter

Abstract

In the current industrial era, there are many uses for utilizing AC (Alternating Current) motors which have 2 types, namely synchronous and induction. Where induction motors are often relied on in the industry for now with 3-phase induction motors. With the above problems, this article discusses the solution for instigating Star-Delta motors using automatic and manual techniques that are widely used in industry with PLC media. As for the following component specifications, such as for pushbutton ON two, special specifications are needed where the pushbutton has one NO contact and one NC contact as shown below For the main contactor (KU) requires 1 NC contact with the notation 21-22 and 2 NO contacts with the notation 13-14 and 43-44. Meanwhile, the Delta (Triangle) contactor requires one NO contact (13-14) and one NC contact (21-22). This chapter focuses on explaining the automatic and manual star delta circuits in the cx programmer and cx designer. Manual star-delta in this series the star to delta transfer is manual or you could say the change is using the action of the user. PLC CP1E is a type of PLC that is prioritized by having a low price but is still efficient by having analog input/output and being able to measure temperature. Starting the motor requires a Star-Delta circuit on the Starting Motor current. This starting is useful for reducing surge currents and also torque when starting. The Star-Delta series is equipped with interlock protection designed to overcome the possibility of “Human Error” due to negligence. Keywords: Control manual, automatic, star-delta circuit

Abstract

Technological developments continue to increase, this can be seen by the increasing number of electronic equipment used in daily needs, one of which is in the science of converting electrical energy, namely the 5-level inverter. The 5-stage inverter is a voltage changer that can convert DC electricity into AC electricity. Many studies have been carried out in order to obtain a sinusoidal 5-level inverter voltage waveform output by means of harmonic elimination technique. Harmonic elimination technique is a 5-level inverter signal processing technique for maximum switching patterns in order to obtain a sinusoidal output waveform and a minimum THD value with a combination of the STM32F407 microcontroller control signal generator circuit and the Mosfet Driver circuit, this 5-level inverter is expected to have a high output waveform. sinusoidal. testing is done with software in the form of PSIM software and real implementation. Based on the results, the method used is able to produce inverter output current and voltage with a THD of 4.38%.

Abstract

Energi listrik merupakan energi utama yang digunakan hampir di seluruh aktivitas dan kehidupan manusia, baik pada sektor perumahan, perkantoran dan industri. Semakin banyaknya penggunaan energi listrik, tentu akan timbul berbagai permasalahan terhadap pasokan listrik. Permasalahan yang sering terjadi yaitu terkait kontinuitas pelayanan listrik dan buruknya kualitas daya yang disalurkan ke konsumen. Oleh karena itu, alat ini bertujuan untuk mengatasi apabila pasokan energi listrik mengalami gangguan atau padam dengan menggunakan DSE 4520 MKII. Dengan sistem Auto Transfer Switch (ATS) dapat melakukan backup daya apabila pasokan listrik mengalami gangguan. Dengan sumber listrik utama dari PLN dan Genset sebagai backup apabila PLN mengalami gangguan. Hasil dari pembuatan alat ini menujukkan bahwa sistem ATS dapat bekerja bengan baik dan dapat beroperasi secara otomatis maupun manual.

Abstract

Energi listrik dari pembangkit yang memanfaatkan pergerakan suatu benda. Seiring berjalannya waktu telah muncul inovasi pembangkit listrik yang ramah lingkungan. Salah satunya dengan memanfaatkan energi air dan energi cahaya matahari (surya). Energi air dapat dimanfaatkan untuk menggerakkan turbin pada mikrohidro, sedangkan energi surya dimanfaatkan untuk menyuplai solar cell. Mikrohidro dan solar cell dapat digabungkan menjadi satu sehingga menciptakan solusi yang lebih efektif bernama pembangkit hybrid. Namun rata-rata daya output yang keluar dari mikrohidro dan solar cell tidak dapat maksimal. Jadi untuk mengatasi hal tersebut kita perlu membuat sistem pengontrolan agar mendapatkan daya output yang maksimal, alat pengontrolan ini dinamakan Maximum Power Point Tracker (MPPT). Tegangan dan arus yang masuk maupun keluar dari MPPT dapat dimonitoring secara realtime menggunakan smartphone berbasis Internet of Things (IoT).
