Abstract

Waste of energy in a building causes increase in operating costs for electricity bills. To solve this problem, a building requires energy management planning. Energy Consumption Intensity (IKE) is used to know the energy requirements usage in buildings. Redesign the lighting and cooling system used a simulation model of room lighting and heat loads using the Dialux simulation software for lighting and DACCS for cooling. The results of energy simulation calculations using the Dialux and DACCS software,lighting that uses energy-efficient lamps and utilizes daylight, with inverter cooling with high coefficient of performance is proven to save energy operating costs of 6,904.32 kWh / month and 82,851.84 kWh / year. The results of the Life Cycle Cost that have been carried out show that the use of the existing system for 5 years costs Rp. 3,014,021,105. By using the redesign system costs Rp. 2,937,693,255. The redesign system can save as much as Rp. 76,327,850.

Abstract

Devices that can convert sunlight energy to electrical energy with photovoltaic effect process made of semiconductors are better known as solar cells. Photovoltaic (PV) or better known as solar power plant (PLTS) is also concerned with several factors to maximize solar energy into electrical energy such as the influence of weather, humidity, temperature of solar cell position and wind direction contained on the surface of solar cells. In this study, this solar cell (photovoltaic) was diagnosed as poly-crystalline during sunny and cloudy weather conditions. The results obtained by the test showed the influence of temperature from the surface of solar cells on the value of output power. Maximum power (Pout) at 11.40 WIB with a slope angle of 35° and a temperature of 47.6°C with an output power value of 100.562 Watt. So it can be said that the temperature is influenced by the intensity of solar radiation that will make the power (Pout) increase, the condition of the poly-crystalline solar module will work optimally at a temperature of about 35 °C - 50 ° C measured on the surface of solar cells.

Abstract

Depo Lokomotif is a work unit that is responsible for locomotive reliability in running the railroad transportation operational business. According to internal monthly report data from February 2019 to February 2020, there were 6 cases of weak locomotive power disruptions that caused operational delays. Analysis was carried out on the CC203 locomotive propulsion system in order to obtain the value of the power reduction in one case of disturbance by comparing the output value against the set standard value. Using mathematical calculation methods from the applicable equations and processing the data on MS.Excell. From the results of the study, the cause of the decrease in locomotive power is due to a decrease in the excitation value so that it affects the output value of the Main Generator at each Notch and has an impact on the motor traction power supply also decreases. The Main Generator can only issue a maximum Horse Power at Notch 8 of 1389.96 HP from 1985.31 HP with a decrease of 595 HP. The electric motion of the generator exciter has the largest decrease at Notch 7 of 6.02 volts from 30.48 volts to 24.46 volts. Motor traction can only output a maximum terminal power of 985.067 Watt from 1407 KWatt. The maximum electromagnetic torque of the Notch 8 motor traction is 2855.48 N.m in the series transition and 3070.21 N.m in the parallel transition. Losses on a series transition of 36886 Watts and a parallel transition of 9122 Watts.

Abstract

In the operation of the electric power system, good quality service is needed. One of them is thevoltage value received by the customer does not get a voltage drop. Based on SPLN No.1: 1978, theservice voltage is a maximum of 5% and a minimum of 10% of the nominal voltage of the LowVoltage Network that is 220 Volt. One of the locations experiencing voltage drop problems is on theCentral Pakandangan Village, Sumenep. Based on an analysis do by the PT PLN UP3 PamekasanNetwork division, it turns out that the voltage drop that occurred on Central Pakandangan Villagecaused by the location. The location is to far from the KH 007 distribution substation, which is 643meters. Then, the area around the location also has a high burden due to the many standingresidential settlements. Therefore, it is necessary to break the load on the network. This method isdone by moving or transferring part of the load from the old network to the new network. Which isthe last 5 poles in this line. so the load supported by one line does not have voltage drop. The resultobtained after performing the load break is that the voltage on the receiving side rises to phase R200 Volt, phase S 212 Volt, and phase T 202 Volt. Where previously the value of the voltage on thereceiving side is phase R 189 Volt, phase S 206 Volt, and phase T 194 Volt.

Abstract

Simulator kereta api sendiri merupakan perangkat latihan masinis sebelum terjun mengendarai lokomotif yang sebenarnya. Simulator kereta api digerakkan oleh empat PMSM yang digunakan untuk menggerakkan simulator pada gerak pitch, roll, transedental, dan longitudinal. Adapun metode pengendali yang digunakan adalah Sliding Mode Control (SMC). SMC terdiri atas dua tahap, tahap pertama berfungsi memperbaiki sinyal kesalahan dengan mengarahkan sinyal tersebut pada sliding surface dan tahap kedua berfungsi untuk mempertahankan sinyal pada sliding surface tersebut. Dari hasil uji simulasi, didapatkan bahwa SMC dapat menjadi solusi sebagai kendali pada sistem simulator masinis kereta api. Pada simulasi gerak pitch, terdapat error steady state pada setiap bentuk SMC. Hal ini, disebabkan oleh faktor non linieritas yang didapatkan motor. Untuk selanjutnya penelitian ini perlu diujii pada perangkat keras simulator kereta api, sehingga dapat bagaimana implementasi SMC pada sistem
