Abstract

PT. PLN (Persero) ULP Batu, The Selecta feeder is one of the 7 feeders in the distribution system that supplies several areas in PT. PLN (Persero) ULP Batu. In the Selecta feeder themselves, the number of error that occurred from January to November 2020 was fourteen times, with details of one time temporary error and thirteen times permanent errors. Delegating a portion of the load from feeders which got error can have an impact on feeders which are working normally. This can cause a voltage drop on the feeder for maneuvering purposes so that the distribution of electric power becomes less than optimal and requires some other loads to be temporarily transferred to other feeders. Based on the problems that occur, it is necessary to analyze the maneuver to reduce the impact of disruption on The Selecta feeder and maintain the reliability value of the distribution system at PT. PLN (Persero) ULP Batu.

Abstract

Mojosari is a customer area consisting of industrial customers and high power customers. Currently, the demand for electrical energy in the area is supported by the Mojoanyar Feeder, which is supplied by the Transformer I Pulling Substation I with a capacity of 30 MVA. The reconfiguration of the feeder was carried out for several reasons, one of which was the addition of power from an industrial customer in the Mojoanyar Feeder area of PT PLN (Persero) ULP Mojosari, namely PT Sinar Karya Duta Abadi (Arwana). If there is additional power, the additional load capacity also increases in a feeder. If the load capacity increases, the current flowing in the conductor also increases. It can be seen from the loading data in February 2021 that the maximum current flowing in the Mojoanyar Feeder during the day is 210 A, the maximum current flowing in the Mojoanyar Feeder at night is 215 A. And if there is a disturbance near the area, the Mojoanyar Feeder will not maneuver because the load is close to the maximum. Therefore, PT PLN (Persero) ULP Mojosari plans a reconfiguration of the feeder by transferring the burden of the Mojoanyar feeder.The analysis was carried out using the simulation program ETAP Power Station 12.6.0. and manual calculations according to standards. After being reconfigured, the Mojoanyar Feeder experienced a decrease in the value of the voltage drop from 8.78% to 7.86%. Mojoanyar feeders experienced a decrease in losses of 5.84% compared to before the reconfiguration of 10.4%

Abstract

In an increasingly advanced era, electrical energy has become a basic resource for humans, the wider and more equitable distribution has greatly influenced the progress of all sectors of electricity users. However, on the other hand, this hydroponic business requires precision and special attention by the actors to support the maximum success of the hydroponic business. Several previous tools have been able to overcome the problem of irrigation for hydroponic plants. However, there is no tool that can regulate the addition of nutrients based on the internet of things and monitor the hydroponics. So, a tool for adding nutrients to hydroponic plants based on the internet of things was designed that is equipped with supervision on plant nutrition. It is hoped that after the manufacture and analysis of tools on hydroponic plants can overcome the problems that are often experienced by hydroponic entrepreneurs.The research was conducted from May to July 2022 in Margoutomo Dalam, Dau, Malang. This nutrient addition tool is designed using an Arduino Uno microcontroller where as a regulator and NodeMCU is added as an online access on the user's cellphone. After the tool has been designed, a regression analysis is carried out to determine the effect of nutrient levels on the fertility of hydroponic plants. The results of this study showed that the nutritional value of a good plant was 350 ppm, with the response rate of this nutrition enhancer at 1.62% per second at a distance of 338 km for testing the user.

Abstract

Technology allows the process of managing catfish remotely, namely catfish managers do not need to manage feeding. In addition, the automated system makes it possible to preserve the quality of catfish as well as savings in feed costs. Today's automated tools mostly use a microcontroller as a controller. Microcontrollers can be programmed to execute commands as needed and at the same time become a form of automation system application in catfish management. In this study, the author designed a microcontroller-based automatic catfish feeding system. The microcontroller used is the ATMega 28 microcontroller which is connected to the RTC DS3231 module. This microcontroller is also equipped with a servo motor that works to move the fish feed valve automatically. The servo motor used is the MG996R servo which has a working voltage of 6V which is sourced from the power supply which is lowered in voltage using step down. The RTC DS3231 module is connected with the arduino uno R3 module, which is the control center of the automatic feed device. The microcontroller turns on following the fish feeding time, which is 8 am and 3 pm. The servo motor will work to open the valve twice in one day automatically with an angle or percentage of the feed valve opening by 35% - 45% for approximately 5 - 10 seconds and the feed that comes out is about 40-70 grams per 10 seconds.

Abstract

In aquaculture production, the number of fish cultivated in freshwater ponds contributes up to 1.1 million tonnes. Catfish(Clarias sp.) is a type of freshwater fish that is quite popular in the cultivation process. The feeding system still has many shortcomings, suchas the amount of feed that is not regular and the timing of feeding which is prone to being irregular. The automatic feeding system requiresa continuous power supply without being interrupted by blackouts from the PLN electricity network. One of the power supply alternatives isto create a power generation system (PLTS). Based on the research results, the solar module capacity is 500 Wp for 1 polycrystalline typemodule, the solar charge controller rating is 20 A, the VRLA battery capacity is 200Ah 12 V KIJO, and the inverter capacity is 850 VA. Theresults of calculations and planning of PLTS can supply electricity with a load power of 1867 watts/hour.

Abstract

At PT. PLN (Persero) ULP Batu, Pujon feeder is one of the 9 feeders in the distribution system that supplies several areas in PT. PLN (Persero) ULP Batu. At the Pujon feeder, the number of disturbances that occurred from January to November 2021 occurred twenty-two times, with details of eighteen temporary disturbances and four permanent disturbances. The number of disturbances that often occur can affect the feeder who is working normally. This can cause voltage drops and power losses, causing the flow of electric power to be less than optimal and detrimental to customers or consumers. Because it requires maneuvering so that the disturbance does not spread to all feeders and cause one feeder to experience a blackout. Based on the problems that occur, maneuver analysis is needed to reduce the impact of disturbances on the Pujon feeder and to maintain the reliability value of the distribution system at PT. PLN (Persero) ULP BATU.

Abstract

There are still monitoring system in Solar Power Plant that do it manually. From here the idea emerged to develop a monitoring system using the IoT concept so that monitoring on Solar Power Plant that can be monitored just by looking at the website page, so current and voltage data can be easily monitored. This monitoring system is used to monitor the current and voltage of a solar power plant with solar cell capacities of 50WP, 80WP, and 100WP. In the application of using Solar Power Plant that, there is a current and voltage starting from the solar cell output, accumulator output, AC load input, and DC load input. The monitoring results that have been carried out will then be automatically sent to the Thingspeak application using the SIM800L Module. The thingspeak application will send data in the form of numbers and graphics in real time. By comparing the value of the measurement results on the Arduino and the Thingspeak application, the value of the percentage of reading errors on the measuring instrument is obtained. 3. In accordance with the tests that have been carried out, the percentage of read errors / errors can occur because of the reading accuracy of the current sensor measurements and AC-DC voltage sensors with different thingspeak applications. Each sensor has a percentage value of 0.16% AC & DC voltage sensor measurement error, 1.2% AC & DC current sensor, and 2.8% data transmission observation.
