In the process of charging laptop's battery, there is no automatic settings are disconnected and connecting the laptop charger voltage according to the needs and desires of the user. In addition, the apathetic nature of the laptop users often also lead to battery charging voltage overload on the laptop battery. These conditions will have an impact on the voltage of the battery leakage which will eventually be more easily damaged. In addition, the electrical energy will continue to flow from adaptor to the laptop and the resulting dissipation of electrical energy within a certain period. From some of these problems, the authors had the idea to make the tool as a form of solution that charging automatic controller. The tool is designed to regulate battery-charging time through additional software on the laptop. The method used was an experimental method. Results of this research have shown that these tools not only cut off the voltage from the adapter to the laptop, but also classes decide the flow voltage of 220V AC power adapter to the charger. Therefore, this tool provides two benefits at once, ie maintain the lifetime of the battery and also save electrical energy use.

The stages include: (1) needs analysis, (2) design, (3) manufacturing, and (4) testing. The design consists of designing a control chain with an Arduino microcontroller, designing a power circuit with Boost-Converter, and box design. The test was conducted at the Department of Electrical Engineering Education Faculty of Engineering UNY. The results of this study in the form of a battery charging device on an electric bicycle automatically with a boost-converter. After testing and comparison with a charging system that uses a 48V inverter and battery charger, the advantages and disadvantages can be known. The disadvantage lies in the reading of sensors that are less stable, relatively lower efficiency, which is an average of 72.15% compared to systems that use Inverters and 48V battery chargers at 84.57%. The advantage is that discharging using a boost converter is relatively longer at 43 minutes, has a control circuit that works automatically, so the energy received by a 12V battery will be effectively channeled to a 48V battery without having to be controlled by the operator. Also available is an external charging port to anticipate if the electrical energy from solar panels is less than optimal.Keywords: boost-converter, microcontroller, electric bicycle AbstrakTujuan penelitian ini adalah untuk menghasilkan alat pengisian baterai pada sepeda listrik secara otomatis menggunakan boost-converter.

Main Disadvantage

Everything that rolls along the ground uses energy to overcome both rolling resistance and air resistance. Air resistance is more significant at higher speeds. Repeated accelerations dominate energy use in stop–start city driving. Not surprisingly, heavy, large SUVs use more energy to go a given distance than lighter, more streamlined cars. Due to the mismatch between the torque required and the rotation rate of the drive wheels, internal combustion engines in cars or trucks do not operate at their peak efficiency. Trains are the most efficient form of ground transportation due to both the lower rolling resistance of steel wheels on railroad tracks and the lower air resistance of its long and thin structure. A further advantage is that rail with fixed tracks can take advantage of the efficient generation of electrical energy. This is also obviously the main disadvantage; trains can only go where tracks have been laid.

Building Information

Buildings contribute more than 40% of world energy consumption, so it is feared that it will cause energy problems in thefuture, especially in the construction sector. One solution to reducing this problem is by analyzing energy use at the initialdesign stage and utilizing solar energy as one of the solar power plants (PLTS) in office buildings. To analyze the use ofenergy in buildings, Building Information Modeling (BIM) was used. The purpose of this research is to analyze the annualenergy level of office buildings in Palembang using BIM software, namely Autodesk Revit. The number of solar panels aswell as the amount of energy were also identified using web-based software (HelioScope) resulting the economic feasibilityas indicated by the installation of solar panels as a component of PV mini-grid. The results showed that the use of BIMtechnology in analyzing building energy can provide a detailed description of the building model at the design stage. Revitanalysis indicates that the building consumed electrical energy per year for about 3,647,713 kWh with a roof area of 1,657m2. In addition, based on the HelioScope analysis, the use of renewable energy from the installation of PLTS was 152,900kWh/year. Meanwhile, for economic feasibility analysis, the installation of PLTS in office buildings can provide a positive NetPresent Value (NPV), indicating a feasible project.

Subsidizing electricity and non-electrical energy products has affected manufacturing output in Egypt, especially given the structure of Egypt’s manufacturing sector which leaning heavily towards capital- and energy-intensive products. This effect is captured in a production function estimated for the twenty industries making up Egypt’s manufacturing sector over the period 2002-2016. With homogeneous parameters, the estimated output elasticity of energy is 0.28. With panel member parameter heterogeneity, the output elasticity of energy is positive and statistically significant in ten manufacturing industries. Negative and statistically significant elasticity is however found in refined petroleum products, fabricated metal products, and electrical machinery and equipment. This indicates suboptimal energy use. Elasticity is also negative, though statistically insignificant, in: textiles, basic metals, and “other manufacturing”. Except for “other manufacturing”, industries of negative elasticity are all energy-intensive.  Moreover, refined petroleum, fabricated metals and basic metals are pollution-intensive. A priority policy measure is to remove subsidies from energy inefficient and polluting industries as opposed to mere ‘across-the-board’ removal.

Control And Monitoring System

The increasing demand for electrical energy and the decreasing supply of fossil fuels in recent years have increased the cost of electrical energy. So that the culture of saving electrical energy is a habit that must be cultivated in the community. On the other hand, energy-saving behavior cannot be realized massively without a support system that can control energy use. With these concerns, it is necessary to develop a method that encourages a culture of saving electrical energy. This paper proposes a system that supports active energy efficiency methods that can support an energy-efficient culture. This system is an electric power monitoring system that is integrated with a smart electrical panel that continuously monitors the use of electrical energy and can control electrical loads automatically, record electricity usage, provide comprehensive reports and analyze energy usage. The method used to carry out this research is research and development. This research has produced a prototype of electrical power control and monitoring system that has a smart panel based on a raspberry PI 3 and PZEM-004t power energy meter. The monitoring system performs and executes automatic control of electrical loads. The system can also provide reports in the form of data monitoring in daily, weekly, monthly or annual period. From the test results, it can be concluded that the system can work well. This research is expected to contribute to providing a system that can support government efforts in saving energy.

The need for electrical energy continues to increase every time. Concerns about the depletion of fossil energy reserves encourage the acceleration of the development of renewable energy use. One of renewable energy is the solar energy. Due to the irreversible irradiation conditions, it takes controls to keep the solar panel's maximum power. The most widely in Maximum Power Point Tracking (MMPT) is Perturb Algorithm and Observe (P&O) but P&O Algorithm has deficiency of oscillations when steady state and MPP trace errors when irradiation changes rapidly. In this paper proposed P & O-Fuzzy algorithm is a modification of conventional P & O to improve the efficiency of solar panels. This research uses Matlab for simulation and hardware implementation using microcontroller Arduino Uno and buck converter topology. The result of simulation and hardware implementation, conventional P & O has an average efficiency of 85.03% while MPPT modification with P & O-Fuzzy algorithm can improve MPP tracking efficiency with 89.67%.
