Abstract

The development of renewable energy in Indonesia has grown quite rapidly, one of which is PLTS. With this new power plant, it is hoped that the excessive use of fossil fuels will be reduced. in 2021 there a new PLTS operating in one of the universities, i.e at the Malang National Institute of Technology with a capacity of 0.5 MWp. The PLTS works on-grid into the Singosari distribution system through the Karangploso feeder so that the addition of a new generator of 0.5 MWp can cause changes in the voltage profile. the voltage profile itself is the voltage condition to be at the nominal voltage either when there is a change in load conditions or when power losses occur in the line with a standard allowable voltage profile of 0.95>V> 1.05 pu. The study used in this research is a power flow study with the Newton-Raphson method. This method is used to calculate the voltage profile on each bus of the power system either during the base case condition or when the system is integrated with PLTS 0.5 MWp. so that with the addition of a new power plant with a capacity of 0.5 MWp, it is necessary to evaluate the addition of a new generator with a capacity of 0.5 MWp to the voltage profile in the Singosari distribution system through the Karangploso feeder.

Abstract

Fires are very detrimental, ranging from loss of property to even loss of life. Fires can be detected when the fire has grown or smoke has billowed out of buildings. Urban areas have densely populated housing so that it has the potential to cause problems in the event of a fire. These fires can be caused by by factors of human negligence and natural factors. Such as the occurrence of short-circuited electricity, negligence in cooking, negligence in burning garbage, and others. Therefore, we need a tool that can detect the presence of an early source of fire so that it does not spread. The problem that often occurs is when a fire occurs, the fire department often arrives late, so there are many losses due to the fire. And the losses can be material and economic. Therefore we need a system that works to control the fire automatically and to extinguish the fire in every house. This study aims to design and build an efficient and affordable prototype. Which later can be applied to housing or warehouses. This prototype is designed using NodeMCU ESP8266 as the main controller, Flame sensor can respond to infrared light beams on the modulation spectrum from 5 to 30 cycles per second, Web Thinger.Io as a server, data storage on the internet of things , and notification of fire in the Blynk application. This system uses a flame sensor based on the Node MCU ESP8266 microcontroller and is equipped with a Buzzer for Alarm and a Mini Water Pump to automatically spray water if a fire is detected. This system utilizes the Blynk Application as an interface to provide notification information about a fire to find out notifications if a fire is detected. And if a fire is detected, it will automatically get a notification from the Blynk application on the "There is Fire" Smartphone and the buzzer will automatically sound and the mini water pump will automatically spray water. In this study, the tool can automatically send Safe and Fire notifications using the blynk application on a smartphone with a delay of < 3 seconds.

Abstract

Water spinach (Ipomoea aquatic) is a vegetable plant that is needed by the community to meet their daily needs. In addition to the cheap price, kale is also good for health, especially preventing diabetes, overcoming anemia, preventing dehydration as well as increasing the immune system. Therefore, water spinach requires automatic watering and fertilizer application to help hydroponic kale farmers in good and efficient care. It can use a control system tool that can run water irrigation and automatic liquid fertilizer application. The tools used are microcontroller, flow sensor, Wemos D1, Soil Moisture Sensor, Real Time Clock, Relay, LCD 1602, and Servo Motor. In addition, using telegram bots as a final notification to hydroponic kale farmers that watering and fertilizer application has been completed, this is synchronized with the control system tool which provides input on the performance of the tool being late. So with the problems above, the author gives the title "Implementation of Control System for Water Sprinkling and Automatic Fertilizer Provision for Hydroponic Water spinach (Ipomoea Aquatic) Plants").

Abstract

Changes in the load on the electric power system suddenly cause dynamic disturbances. The disturbance causes the stability of the generator to be disturbed, because the generator does not respond to the disturbance quickly. This causes oscillations in the generator in the form of oscillations of frequency and rotor angle. One of the additional control equipment that can increase the stability of a generator is the Power System Stabilizer (PSS). With the PSS installation, the optimal frequency response and rotor angle of the SMIB system are obtained, indicated by the minimum system overshot response. The controller is able to provide stability so that overshoot oscillations can be suppressed, as well as faster settling time performance for the system to reach steady state conditions. To test the stability of the SMIB system, a case study of adding and subtracting loads is used, with the proposed control method using PSS.

Abstract

Multiple-input multiple-output (MIMO) is a transmission technology that uses more than one antenna both on the transmitter side and on the receiver side. In the communication services, the system will involve more than one active user who uses one base station (BS) together so that it is called multi-user MIMO (MU-MIMO). This paper discusses the performances of MU-MIMO when it uses block diagonalization (BD) precoding and applies minimum mean squared error (MMSE) detector. As a comparison we also apply zero-forcing (ZF) detector. From the simulations that have been done, it is found that the MMSE had better performances than the ZF detector in terms of BER. We also consider the performance when users are moving. The simulation results show that BER performances are decrease slowly when users are moving.

Abstract

Lightning strikes can cause protection failure at substations such as equipment damage at substations due to insulation failure or what is known as flashover. Because of that, a lightning strike protection system is needed to minimize the occurrence of direct lightning strikes to equipment and buses at the substation. This study discusses the modeling of the protection of the substation from direct lightning strikes using the rolling sphere method at the Wonosari-pedan 150 kV substation using lightning rod poles. The calculation results show that with the configuration of a lightning rod as high as 21 m and the use of a ground wire of 17.8 m it meets the safe criteria for the height of the protected area in the case study of this research.
