Abstract

A  new  voltage  control  method  for  single-phase  full-bridge PWM inverters  that having an output LC filter  is proposed in this paper. The proposed voltage  controller has a capability to realize a zero steadystate output voltage error with fast response. The zero steady-state output voltage error is achieved by using a controller that is derived by using the virtual LC resonant circuit. Fast response is obtained by using a virtual resistance  that  is  connected  in  parallel  with  the  filter  capacitor.  The validity of the proposed method is verified by experimental results.

Abstract

Pada sistem pembebanan yang tidak seimbang dalam sistem tiga-fasa empat-kawat, susut daya pada saluran distribusi akan lebih besar dibandingkan pada kondisi beban tidak seimbang. Hasil analisis menunjukkan bahwa pada kondisi pembebanan yang ekstrim dimana beban hanya terpasang pada salah satu fasa saja susut daya pada saluran distribusi akan lebih besar enam kali dibandingkan pada kondisi beban seimbang.

Abstract

Kegiatan masyarakat di era sekarang yang serba digital menggunakan teknologi tanpa kabel (wireless). Teknologi tanpa kabel menjadi andalan komunikasi, namun seiring perkembangann zaman, ada sebuah teknologi tanpa kabel dengan memanfaatkan cahaya tampak. Teknologi ini dikenal dengan istilah visible light communication (VLC). Sistem VLC terdiri dari bagian transmitter dan receiver. Transmitter berupa komponen-komponen elektronika yang terintegrasi dengan cahaya tampak sebagai media transmisi. Pada penelitian ini membuat bagian transmitter dan receiver untuk komunikasi audio. Cahaya tampak sebagai media transmisi menggunakan laser led karena cahaya dari laser led ini lebih fokus dan pancaran cahayanya lebih jauh dibandingkan dengan yang lain. Sedangkan di sisi receiver menggunakan solar panel sebagai penerima sinyal informasi yang dikirimkan. Penelitian ini berhasil membuat sebuah sistem komunikasi audio berbasis visible light communication. Variasi jarak antara transmitter dan receiver mempengaruhi kualitas suara yang diterima. Pada jarak 500 cm kualitas suara yaitu 99,2 dB pada kondisi gelap dan 99,1 dB kondisi terang. Perubahan sudut pancar transmitter terhadap receiver juga mempengaruhi hasil kualitas suara. Kualitas suara terbaik pada sudut 900 di kondisi terang dengan jarak 50 cm sebesar 97,9 dB sedangkan di kondisi gelap dengan jarak 50 cm pada sudut 1000 sebesar 98,1 dB. Abstract The people activities in today's digital era use wireless technology. Wireless technology has become the mainstay of communication, but along with the times, there is a wireless technology that uses visible light. This technology is known as visible light communication (VLC). The VLC system consist of transmitter and receiver. Transmitters are electronic components that are integrated with visible light as a transmission medium. In this study, the transmitter and receiver are made for audio communication. Visible light as a transmission medium uses an LED laser because the light from this LED laser is more focused and the light beam is farther away than the others. While on the receiver side using a solar panel as a receiver of the information signal that is sent. This research succeeded in making an audio communication system based on visible light communication. Variations in the distance between the transmitter and receiver affect the quality of the received sound. At a distance of 500 cm in dark conditions, the sound quality is 99.2 dB in light conditions and 99.1 dB. Changes in the beam angle of tranmitter to receiver also affect the sound quality. The best sound quality at an angle of 900 in bright conditions with a distance of 50 cm is 97.9 dB while in dark conditions with a distance of 50 cm at an angle of 1000 is 98.1 dB.

Abstract

The electricity demand continues to increase every year in line with advancing technology and society's dependence on electricity supply. The society's reliance on electricity drives the improvement of power quality by PLN, one of which is the enhancement of voltage quality. At PT. PLN (Persero) Unit Layanan Pelanggan (ULP) Plered, there is a distribution feeder with an end voltage that is still below the standard. In this study, an analysis of the system related to the improvement of voltage drop on the GNAP distribution feeder was conducted with the assistance of ETAP simulation. The voltage drop improvement was carried out using the load splitting method, which involves redistributing a portion of the load to another feeder. The obtained results show that the voltage drop on the GNAP feeder decreased from the initial 1.19 kV to 0.84 kV during daytime load and from 1.24 kV to 0.90 kV during nighttime load. The voltage loss also experienced a decrease from the initial 5.95% to 4.18% during daytime load and from 6.20% to 4.51% during nighttime load.

Abstract

An earthquake is a vibration that occurs due to plates at the base of the earth rubbing against each other. An earthquake can have several impacts, namely material loss and loss of life and trauma for some people who feel it. This happens because people are not fast enough in getting information. Therefore we need an earthquake detection device that is relatively inexpensive. In this study designed a prototype for earthquake early detection using Frequency Modulation (FM) communication. The components of this system are Arduino Uno which functions as a microcontroller, SW-420 vibration sensor to detect vibrations, buzzer as the output of the SW-420 sensor in the form of sound and FM transmitter V2.0 which functions as a medium for transmitting radio frequency signals and sending sound from the buzzer . The level of vibration that indicates that an earthquake occurred namely 3-5 with a conversion of 5-10 SR. The system would have the ability to provide information in the form of sound received by a radio or FM receiver. The distance that can be emitted by the FM transmitter module V2.0 is 17.87 meter

Abstract

Universitas Jenderal Achmad Yani, whose major campus is in Cimahi City, is constructing a large-scale campus development, the size of which is directly proportionate to the quantity of energy consumed. This increase in electrical energy consumption can be minimized by utilizing environmentally friendly renewable energy sources to supply loads and reduce the use of existing energy from the grid (PT. PLN). This context supports a design proposal for the production of photovoltaic-based photovoltaic on the Universitas Jenderal Achmad Yani campus, particularly in two buildings with exceptional roof potential. In this paper, the modeling carried out aims to help supply renewable energy-based electrical energy. The design of PV on Grid Installation Engineering in Buildings at Universitas Jenderal Achmad Yani carried out in this paper includes PV placement layout, PV construction, and simulation using PVsyst. The rooftop-type grid-connected PV is modeled in the Faculty of Health Sciences and Technology (FHST) Building and the Rectorate Building, which are composed of PV panels, inverters, and other supporting components. Grid PV design and simulation modeling on the roofs of FITKES and Rectorate Buildings resulted in a total installable PV capacity of 420 kWp, an annual average Performance Ratio of 80.6%, and an average potential energy output of 702 MWh/year. This energy potential is undoubtedly proposed to fulfill future electricity needs.

Abstract

This study evaluated the kinetic characteristics of the ethyl acetate saponification reaction using two analytical approaches, namely conductometry and titrimetry, in a stirred batch reactor system at various temperature conditions. Both methods showed that the reaction followed an overall second-order pattern, in line with the theory of saponification reaction kinetics. However, significant differences were found in the conversion values and activation energy obtained. The titrimetric method showed higher reproducibility and accuracy, with an estimated activation energy of 37.40 kJ/mol. This study also confirmed that increasing the reactant concentration accelerated the reaction rate by increasing the frequency of effective intermolecular collisions. Overall, the titrimetric method is recommended as a more reliable approach in the study of saponification kinetics in this experimental system.
