Abstract

AbstractDuring the distribution process there will be a loss of some of the energy that is channeled. This phenomenon is known as losses. This is caused by technical and non-technical factors. In the  State Electricity Service (PLN) system, distribution losses or energy losses is calculated by measuring the difference between kWh produced and kWh sell. This kWh difference is the electrical energy lost during the starting process from the generation or secondary side of the Substation to customers’ APP. Cumulatively, the amount of kWh at all base sources is 73,769.524 kWh while the distribution loss that occurs in JTM is 5,835.008 or 7.91%. One way to overcome and minimize distribution losses in the 20 kV Procurement Service Unit (ULP) of Lima Puluh distribution system is to analyze the distribution network system, add new feeders and break the load on the electrical system. The simple branch exchange method is used to separate the network load, which is done by adding a switch by turning the on or off channel and searching for the configuration that produces the smallest power loss and calculating the power loss based on the network load. Based on the simulation results using the ETAP 12.6 software, the results of the energy loss of Procurement Service Unit (ULP) of Lima Puluh is 5,864,112 kWh then decreased after load separation of 4,341,348 kWh. The value of power loss before load separation is 1,955 kW and a decrease in power loss after load separation is 1,484.5 kW. The investment cost incurred for the construction of a new feeder is RP. 22,000,000,000,- with a payback of 9.9 years.  Keywords: Feeder, Power Loss, Energy Loss, ETAP 12.6.

Abstract

An egg incubator is a tool that helps the process of hatching eggs using an electric heater and is equipped with an egg rack that functions to evenly distribute the heat in the incubator. Good temperature control in the hatching process is something that greatly affects the hatching results. In this study, an egg incubator temperature control system was designed using the PID method with the Ziegler Nichols Open Loop Step Response tuning method. The control system is specifically for free-range chicken eggs which require a normal temperature of 37 °C-39 °C. The main control components are the microcontroller, the incandescent lamp heater, and the DHT22 temperature sensor. The open loop test shows a time delay of 20 seconds and a time constant of 385 seconds, so with the Ziegler Nichols open loop tuning method, the values of Kp = 23.1, Ki = 40, and Kd = 10. The test results show that the PID controller can control the temperature properly. In testing the hatching process within 21 days, the temperature control worked well, and the effect of changes in day and night temperature did not significantly affect the performance of the PID controller.

Abstract

AbstrakEnergy measurement using a kWh meter must have good accuracy. The increasing use of non-linear electrical equipment causes harmonics in the network. This study aims to measure and analyze voltage, current, power, power factor and the percentage of Total Harmonic Distortion (THD). The research was carried out by designing and making a device in the form of an electrical circuit connected to a semi-digital kWh meter with a fixed load of 10 incandescent lamps with a power of 100 watts each and 1 single-phase induction motor. The test results show that the incandescent lamp load test produces a THD-I percentage of 3.5% and a THD-V percentage of 3.7% with a measurement error value of 0.675%. In the motor load test, the percentage of current harmonics becomes high at 16.6% and the THD-V percentage is 3.4% and the measurement error value is 3.48%. In testing the variation of the load combination of an induction motor and incandescent lamps, the percentage of THD-I is 5.8% and the percentage of THD-V is 3.2% with an error value of 3.57%. The greater the THD percentage value, the greater the reading error on the semi-digital kWh meter and the worse the resulting power factor value. Kata kunci: Non-linear load, kWh Meter, THD

Abstract

In the preparation of the thesis, students need a supervisor as a place of consultation in completing the thesis. The supervisor should be a person who mastered the field in accordance with the topic of student thesis, so that the guidance process can run optimally. Thesis is one of the graduation requirements to obtain a bachelor's degree. Generally, the selection of thesis supervisors is decided by the study program through a meeting of lecturers to determine which lecturers are in accordance with the title and description of the students who took the thesis course. To solve this problem, a solution is needed that can take into account the specifications of lecturer expertise that suits the needs of students. The Entropy method is an alternative to solve this problem. This method was chosen because it is able to select the best alternatives from a number of alternatives, in this case the intended alternative is to be a supervisor and examiner based on the specified criteria. Research is carried out by looking for the weight value for each attribute, then a casting process is carried out that will determine the optimal alternative, namely the four lecturers whose specification values are highest.Keyword: Decision Support System, Entropy, Thesis
