Power-electronics based Compact Fluorescent Lamps (CFLs) have been proven to reduce electrical energy consumption for lighting purpose. As in common power-electronics-based electrical devices, CFLs can be categorized as non-linear loads. Therefore, the input current has a non-sinusoidal waveform and contains harmonics. This paper discusses the advantages and disadvantages of CFL application and proposes the attachment of THD value to the product package in order to improve the marketing policy. Total Harmonic Distortion (THD) is a method used to find the percentage value between the total harmonic components and their fundamental components. The percentage of THD causes the greater risk of damage to equipment due to harmonics that occur in current and voltage. Laboratory testing shows that a CFL sample has THD of the input current as high as 67.7%. This THD is relatively high and may degrade the electrical power quality. Moreover, it could lead to the misreading of electrical power and energy meter. Several experiment results are shown and analyzed to confirm the validity of the discussed matter.

Currently, people are increasingly using energy saving lamp (LHE) and LED because of their energy saving and low power consumption. But the use of LHE and LED in large quantities can reduce the quality of electric power. This is because LHE and LED are classified as non-linear loads which are a source of harmonic distortion for low-voltage power lines. Harmonic distortion occurs due to non-linear load currents that experience distortion or defects. Based on this, this study aims to investigate the effect of the collective use of LHE and LEDs on the quality of electrical power, such as: harmonic levels, power factor, and the resulting harmonic current and voltage waveforms. The results of this study indicate that the simultaneous use of LHE and LED with a total of 60 pieces causes distortion of the current waveform with THDi of 63.97% exceeding the standard value of IEEE Std 519-2014, with dominant harmonic currents in the 3rd order with a THDi of 74% and order 5 with a THDi of 37.6% and a THDv value of 2.44%, still below the 5.0% standard of IEEE Std 519-2014. This high THDi value has a negative impact on the low PF value of 0.722, which does not meet the power factor requirements of â‰¥ 0.85 according to PLN standards. And if the true power factor (TPF) value is calculated, the TPF value is 0.608 which is lower than the PF value of 0.722. The results obtained from the Matlab simulation show conformity to the results obtained from experimental measurements in the laboratory, namely: the simulated harmonic waveform approximates the measured harmonic waveform.

Based on the location of Indonesian astronomy which is located on the equator, it is very appropriate or feasible if Indonesia develops PLTS as a technology to offset human demands for dependence on electricity. Indonesia also has a tropical climate (consisting of 2 seasons, hot and rainy), so that solar radiation in the territory of Indonesia (± 12 hours) is sufficient to make PLTS a solution for the demands of electricity needs. One of the technologies used in PLTS is solar panels. Solar panels are able to convert sunlight into electricity directly. The performance of solar panels is influenced by several factors, namely solar radiation, temperature and wind speed. Calculations and analysis of the measurement results show that the performance quality of solar cells is not very good, namely 0.143 for solar cells without reflectors, 0.156 for solar cells with galvalume roof reflectors and 0.157 for solar cells with aluminum foil reflectors. And the efficiency of solar cells without reflectors is 7.48%, for solar cells with galvalume roofs is 8.75%, and for solar cells with aluminum foil is 9.72%

Harmonics are multiples of the base frequency (50 Hz) in electrical energy systems, resulting from increased use of nonlinear loads in industry, offices, education and households, resulting in increased harmonic distortion in distribution networks. Computers and laptops are nonlinear loads that are a source of harmonic currents in electrical systems and are widely used by the public. High harmonics can damage electrical equipment. This study discusses harmonic problems caused by computers and laptops of different brands, in order to know the values of THDv, THDi, dominant order THDi, current harmonic wave equations and current waveforms. To conduct this study, PQA Kyoritsu KEW 6315 measurement data was analyzed using the Fourier series method and then a simulation of FFT Matlab Simulink was carried out. The results of this study show that the THDv values on computers and laptops of different brands, as a whole meet the IEEE 519-2014 standard, while the THDi values range from 80% to 86.96% which do not meet the IEEE 519-2014 standard. The dominant harmonic current order generated by computers and laptops of different brands has the same trend pattern in the dominant harmonic current order that occurs in the 3rd, 5th, 7th and 9th order, where the 3rd order has the highest dominant THDi value with a range of values between 40% to 52.17%. Also obtained is the wave equation of harmonic currents generated by computers and laptops using the Fourier series based on the same order of dominant harmonic currents from the measurement results, namely in the 1st, 3rd, 5th, 7th, and 9th order.

The PLTS designed in the LPPM UKI-Jakarta building is an on-grid PLTS with the aim of lowering electricity bills. In analyzing this design, both from a technical and economic perspective, the PVSyst application tool was used. The intensity of solar radiation at the study site is 1654.1 kWh/m2 per year and the electrical energy that can be generated is 17,726 kWh/year using solar modules, a capacity of 10,675 Wp. Savings in the cost of paying for electricity using PLTS amounted to IDR 15,953,400 and the break even point of PLTS is 9.64 years, calculated after construction has been carried out. The construction of this PLTS also reduces CO2 emissions in Jakarta, due to the use of electricity from fossil fuels by 158.1 tons for 25 years. Based on the simulation results and engineering economic calculations from the PLTS being built, a reduction in the cost of using electricity was found to be 50% of the total cost of paying for electricity each year.

This research was conducted on BTS in the Mechanical Engineering Study Program Building, Faculty of Engineering, UKI, Jakarta with the aim of knowing the harmonics on the neutral wire of BTS which includes the level of voltage and current distortion due to the use of non-linear electrical components in BTS. In this study, the standard used as a reference is the IEEE 519-2014 standard. Based on the results of the research conducted, it was found that the Total Harmonic Distortion Current (THDi) at BTS was 224.72% and did not meet the standards. The dominant harmonic currents are 3rd order with 219.02% THDi and 9th order with 47.56% THDi which exceed the IEEE 519-2014 standard limits. And Total Harmonic Distortion Voltage (THDv) is 1.59% and meets the standard. The simulation results of a single tuned LC passive filter can reduce the THDi level of the current flowing in the BTS by 217.66% using Matlab/Simulink software. The current flowing in the neutral wire is based on a measurement of 1.1 amperes with a THDi value of 224.72%, and after being filtered, the THDi drops to 7.06%, but still does not meet the standard. The dominant harmonic currents flowing in the neutral wire are 3rd order with 219.02% THDi and 9th order with 47.56% THDi, which exceed the standard limit and 1.59% overall THDv.

This study analyzed the harmonics of single-phase transformers loaded with Direct Current Motor (MAS) and rectifier using quantitative method approach. The purpose of this study was to identify the Total Harmonic Distortion (THDi) value in transformers and design passive filters to reduce harmonic levels if they do not meet the standards. The results showed that the measurement results, obtained THDi 31.01% in zero-load transformers, in transformers with MAS load with half-wave rectifiers, THDi by 79.35%, and in MAS load transformers with full-wave rectifiers, THDi by 46.40%, which exceeded IEEE 519-2014 standards. The results of the single tuned LC passive filter simulation showed that the MAS loaded transformer with a half-wave rectifier decreased harmonic level from the THDi value of 79.35% before using the filter, to 1.04% after using the filter and met IEEE 519-2014 standards. The harmonic level of MAS loaded transformer with full wave rectifier, before filtering, THDi 46.40%, but after filtering, THDi 37.98%, still exceeds IEEE 519-2014 standard.
