Abstract

Pembangkit tenaga listrik thermal merupakan suatu pembangkit yang menghasilkan energi listrik yang berasal dari energi thermal. Energi thermal bisa dihasilkan melalui pembakaran bahan bakar berupa gas ataupun batubara. Berdasarkan hal tersebut, pada pembangkit tenaga listrik thermal konsumsi bahan bakar sangatlah mempengaruhi biaya produksi energi listrik, sehingga diperlukan suatu teknik pengoperasian pembangkit yang optimum. Salah satunya pada PT Indonesia Power UPJP Perak Grati yang merupakan perusahaan pembangkitan tenaga listrik yang dalam pengopeasiannya memerlukan cara dalam penghematan bahan bakar gas berdasarkan nilai heat rate (Kcal/kWh) khususnya dalam penghematan biaya pokok produksi. Pada penelitian ini Particle Swarm Optimization (PSO) digunakan sebagai metode untuk penentuan daya optimal pada generator Pembangkit Listrik Tenaga Gas (PLTG) Perak Grati. Berdasarkan hasil penelitian, dihasilkan adanya penghematan konsumsi gas antara metode PSO dengan kondisi aktual, dimana saat permintaan daya 310 MW, terjadi penghematan konsumsi gas sebesar 0.5968 BBTU/h atau setara dengan Rp 57.168,00/h.

Abstract

The use of electrical energy is very important for household needs. The greater the use of electrical loads, the greater the need for electrical energy. Every electrical load has a power factor. A low power factor value <0.8 causes power and current usage to be less than optimal. This can be caused by the large use of inductive loads such as electric pumps, electric heaters, TL lamps, and so on. To overcome this, it is necessary to improve the power factor by using capacitors. In this paper, power factor improvement is designed using the Fuzzy Logic method as a data processor embedded in the microcontroller to determine the capacitor variable supported by a sensor to read the values of current, voltage, power, cosphi, and frequency in the electric current as input to the microcontroller and a combination of relays as output to determine the best capacitor value so that the power factor is improved to > 0.8.The use of electrical energy is very important for household needs.

Abstract

Currently, the construction sector is increasingly developing among the community and business actors. There are various types or types of products on the market provided by concrete mixer manufacturers, such as double shaft mixers which are more efficient for mixing concrete mix so that homogeneity is well maintained. In concrete mixer products currently circulating on the market, there is no monitoring and controlling system for synchronization in the second gear-box rotation, which can prevent fatality damage from occurring. This research aims to create a synchronization monitoring and controlling tool for a double-axis concrete mixer to minimize damage due to use. In the second round, the gear box is corrected to maintain synchronization with the proximity sensor by sending information to the microcontroller which will be displayed on the LCD in the equipment operator's work area and can be accessed outside the operator's work area via a smartphone based on local WiFi network in the company area. If there is a difference in synchronization between the two gear-boxes, the microcontroller will automatically give a command to the relay to turn off the motor driving the two gear-boxes and it can be turned off directly via smartphone.
