Abstract

This paper describes the three-phase induction motor protection system used in PT South Pacific Viscose. The induction motor studied is a motor with a power of 90 kW. The nominal current obtained from the calculation is 151.934 A. Protection system in the form of MCCB and TOR. From the results of the calculation of the MCCB rating that must be used 379.835 A and the TOR rating of 189.917 A, while the installed MCCB is 400 A and TOR 200 A. By comparing the results of calculation observations with the field, it can be concluded that the use of the protection system is appropriate.

Abstract

Abstract  The development of technology in modern times is growing very fast. Very increasingly sophisticated technology, the human need for data rates is very high to balance this technology. So that PT. TELKOM INDONESIA made a network design in the form of Fiber To The Home using fiber optic cable as the transmission system. The design of Fiber To The Home is a network from the center to the customer with mapping int the form of distance, device placement, device specifications, and how many devices will be used. The design result show that the design for the BTR Blok O Bekasi area uses 1 ODC, 23 ODP, and 72 customers. The average total attenuation analysis using the link budget calculation shows 20,3064159 dB for distribution 1 and 20,52062 dB for distribution 2. This attenuation is in accordance with the standarization that has been implemented by PT. TELKOM INDONESIA 28 dB.

Abstract

Abstrak - Gangguan yang umum terjadi pada saluran distribusi tenaga listrik ialah ketidakseimbangan beban yang disebabkan karena beban satu fasa jaringan tegangan rendah pelanggan. Ketidakseimbangan yang terjadi pada transformator dapat mengakibatkan kualitas dari tenaga listrik rendah sehingga berpengaruh terhadap kualitas sistem penyaluran tenaga listrik, dengan demikian perlunya pemerataan beban antar fasa transformator distribusi. Tujuan dari penulisan ini adalah untuk mengetahui persentase pembebanan   dan ketidakseimbangan beban transformator distribusi, sehingga gangguan yang terjadi pada saluran distribusi dapat diatasi. Selain itu, tujuan lainnya adalah untuk mengidentifikasi beban lebih pada transformator distribusi. Berdasarkan hasil perhitungan dan simulasi, didapatkan hasil persentase rata-rata ketidakseimbangan tertinggi adalah trafo 1 pada malam hari yaitu sebesar 21,6%, persentase nilai tersebut melebihi standar yang telah diatur oleh IEEE sebesar 20%.  Adapun dasil yang didapat pada pengukuran tidak menunjukan adanya beban lebih pada semua transformator gardu E308, karena nilai arus fasa kurang dari arus nominal yaitu tidak melebihi 80% dari standar batas beban lebih.

Abstract

Voltage Detector is a tool that can read the output voltage value of a generator. Voltage detector on the controller serves as a voltage detector input controller derived from the generator. The output of the Voltage detector is an analog signal processed by the microcontroller to then activate the relay and then forward the input voltage when the input voltage is in accordance with the provisions to the rectifier circuit. The output of this Voltage detector is an analog signal so it needs to be connected with a microcontroller ADC for processing. Voltage detector is prepared using the concept of voltage divider between 2 pieces of resistance.  At resistance 1, it is the result of a series and parallel circuit relationship between the 9 receipts used. When the maximum rectifier output voltage is 200V and the maximum output voltage of the designed detector is no more than 5V, then the value of the components used is set according to the needs. Resistor resistance values 1 to resistors 9 are determined at 56KΩ and capacitors are used as large as 1μF.

Abstract

Abstract  The interconnectedness of the times includes all aspects, one of which is the temperature of the earth which is getting warmer, the annual prediction of increasing by 1 ° to 1.5 ° Celsius. In addition, there are technological updates with ideas that are a daily necessity. Evaporative Cooler is a conventional air conditioner throughout the world with various types and types, DEC (Direct evaporative Cooler), for example works by converting sensible heat into latent heat, whose main circuit consists of an electric motor, swing cooler motor and 24V DC water pump, a actuator module used in the implementation of this system. The idea that came up was that not many people paid attention to the system its use. This research will apply one of the wireless communication, namely the Bluetooth HC-05 Module in the control model design using ECOSYSTEM (Evaporative Cooler System) where the input is integrated with an artificial application installed on a smartphone with Bluetooth devices in it with the android operating system so that it can communicate between systems. Focusing on the communication performance applied by the HC-05 with a 2.4GHz frequency as a receiver or sender of commands with a range of signal distances that can be given, equipped with an Arduino UNO ATMega328 microcontroller for core system controllers. Over-the-air communication model that does not require other media devices in the process of working. Measurement of the performance of the signal coverage is proven horizontally and vertically, intended because there is a difference in the capture power of the transceiver and receiver signals as well as the conditions when bluetooth is controlled, it is connected and not yet connected. In the test, bluetooth only captures two conditions when it is working, when it is still affordable, bluetooth will connect and remain connected with a delay of not more than 0.02 seconds or not connected at all when the range is getting farther.
