Abstract

The circulation of Energy Saving Lamps or Self-Based Lamps in Indonesia, which promises the shape of lamps, variations in lamp power, lamp life, comparison of offered lamp brightness, low power absorption with brighter light, has caused many people to switch from using tube lamps and incandescent lamps to other types of lamps. this lamp. Indonesian Government regulation that requires LHE lamp manufacturers to include the Indonesian National Standard label as proof that the lamp is within the specified Efficacy limit. General Regulation of Electrical Installation and PT. PLN urges its consumers that electricity users can maintain the load power factor of not less than 0.8. This study aims to determine the amount of current consumption and electrical power required by LHE lamps labeled with SNI from the Panasonic, Shinyoku and ACR brands which were obtained randomly in the market. 10 lamps 18 watts, 220 volts as a sample, given a variation of the supply voltage between 110 volts to 240 volts with 10 volt steps. The results showed that the average real power at a voltage of 220 volts was in accordance with the labels on all brands. All three lamp brands have a power factor below 0.5. Characteristics of voltage to real power for Panasonic LHE obtained y = -0.0226x2 + 8.889x - 673.88, LHE Shinyoku y = -0.0002x2 + 0.3184x + 109.22, and LHE ACR y = -0.0003x2 + 0.2852x + 120.91

Abstract

Pengoperasian PLTG (Pembangkit Listrik Tenaga Gas) blok 2 di Grati masih kurang efisien, dikarenakan sering berubahnya pembebanan pada generator. Berdasarkan laporan efisiensi pembangkit UPJP Grati tahun 2018 untuk unit 1 sebesar ±27%, unit 2 sebesar ±27% dan unit 3 sebesar ±26%. Efisiensi blok 2 harus dijaga semaksimal mungkin, yaitu dengan cara menentukan beban yang optimal pada masing-masing unit generator di blok 2. Metode siklus brayton digunakan untuk menentukan beban yang optimal dengan menghitung efisiensi thermal dari PLTG. Parameter yang dibutuhkan yaitu tekanan dan temperatur sisi inlet dan outlet dari kompressor dan turbin. Hasil dari metode ini diketahui bahwa beban yang optimal pada masing-masing unit di blok 2 yaitu dibeban maksimum (100 MW). Pada metode ini juga diketahui unit yang paling tinggi efisiensinya yaitu unit 1 sebesar 33 % sedangkan unit 2 sebesar 31.3 % dan unit 3 sebesar 31.7 %. Jika blok 2 dioperasiakan dengan pembebanan 100 MW maka efisiensinya akan maksimal dibandingkan dengan pembebanan yang berubah-ubah seperti sekarang.

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.
