The erratic power supply has been a growing cause for concern in developing countries. It becomes more challenging to supply adequate energy in countries with a high population due to the increased demand and this has led to load shedding and spreading in Nigeria. Also, emissions from power plants, impacts of hydroelectric development, and risks associated with nuclear energy use have been targets for political action due to the recent pursuit of sustainability development. Also, evidence of depletion of the protective ozone layer and its impact on the environment have urged the need for rapid development of alternative power generation method void of causing adverse environmental impact. This paper, therefore, discusses the design and evaluation of a self-starting fuel less power generator using DC motor as the prime mover to generate electrical energy from an alternator. The alternator armature shaft was coupled directly with DC motor powered by a rechargeable battery. The DC motor rotates the armature of the alternator in the field coil at high speed when activated from the starting switch, which results in alternating current output voltages of 220V.

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.

Prosthetic Finger

Current designs of powered prosthetic limbs are limited by the nearly exclusive use of DC motor technology. Soft actuators promise new design freedom to create prosthetic limbs which more closely mimic intact neuromuscular systems and improve the capabilities of prosthetic users. This work evaluates the performance of a hydraulically amplified self-healing electrostatic (HASEL) soft actuator for use in a prosthetic hand. We compare a linearly-contracting HASEL actuator, termed a Peano-HASEL, to an existing actuator (DC motor) when driving a prosthetic finger like those utilized in multi-functional prosthetic hands. A kinematic model of the prosthetic finger is developed and validated, and is used to customize a prosthetic finger that is tuned to complement the force-strain characteristics of the Peano-HASEL actuators. An analytical model is used to inform the design of an improved Peano-HASEL actuator with the goal of increasing the fingertip pinch force of the prosthetic finger. When compared to a weight-matched DC motor actuator, the Peano-HASEL and custom finger is 10.6 times faster, has 11.1 times higher bandwidth, and consumes 8.7 times less electrical energy to grasp. It reaches 91% of the maximum range of motion of the original finger. However, the DC motor actuator produces 10 times the fingertip force at a relevant grip position. In this body of work, we present ways to further increase the force output of the Peano-HASEL driven prosthetic finger system, and discuss the significance of the unique properties of Peano-HASELs when applied to the field of upper-limb prosthetic design. This approach toward clinically-relevant actuator performance paired with a substantially different form-factor compared to DC motors presents new opportunities to advance the field of prosthetic limb design.

The rapid development of electric vehicles stimulates the development of structures related to their operation. Including the use of the range extending engine for electric vehicles. The use of gas turbine engines for vehicles has always been of interest. The microturbine in the range extending engine is relevant today. However, the possibility of using a microturbine as part of a range extending engine is possible under several conditions. Microturbine should be successfully mated with a high-speed generator, and the whole structure should have a high efficiency and be economically advantageous. To create such a design, it is necessary to develop a simple microturbine with a design, equipped with a highly efficient heat exchanger, which allows to obtain high fuel and operational efficiency. Microturbine should have low temperatures on the turbine wheel to maintain high environmental parameters. The use of composite materials is necessary. The results of the development and technical characteristics of a single shaft microturbine of this class for use with a high-boring generator are presented, and its applicability as a range extending engine is justified. The main problems solved in the design of microturbines are shown: issues of thermal conditions, optimization of blade machines, flow in gas-air pipes. Power plants, based on the microturbine and high-speed generator, can be widely adopted on the basis of their simple and high operating characteristics, including the range extending engine as a range extending engine.

The Waves

The need for electrical energy has increased every year. On the other hand, the largest power plants in Indonesia still use non-renewable energy sources such as coal and petroleum, while these non-renewable energy sources will eventually run out. To anticipate running out of this energy, a renewable energy source is needed. This existence will not run out even though it is consumed every day. Renewable energy that can be used for conversion into electrical energy in coastal areas is wave power.  The waves that always crash on the shoreline can be used to drive turbines. The turbine rotates due to the crashing waves connected to a DC generator. It will convert mechanical energy into electrical energy. The electrical energy generated by the DC generator is used to charge the battery. The purpose of this research is the know-how to design a wave power generator and to determine the performance. The experimental method is used in this study. In the results, the generator works optimally during the day with the resulting voltage of 10.6 V to 10.7 V with rotation speed of 623 Rpm to With 710 Rpm.

Inherent Feature

The modeling system is a process to define the real physical system mathematically, and the input/output data are responsible for configuring the relation between them as a mathematical model. Most of the actual systems have nonlinear performance, and this nonlinear behavior is the inherent feature for those systems; Mechatronic systems are not an exception. Transforming the electrical energy to mechanical one or vice versa has not been done entirely. There are usually losses as heat, or due to reverse mechanical, electrical, or magnetic energy, takes irregular shapes, and they are concerned as the significant resource of that nonlinear behavior. The article introduces a nonlinear online Identification of a high-speed bidirectional DC motor with dead zone and Coulomb friction effect, which represent a primary nonlinear source, as well as viscosity forces. The Wiener block-oriented nonlinear system with neural networks are implemented to identify the nonlinear dynamic, mechatronic system. Online identification is adopted using the recursive weighted least squares(RWLS) method, which depends on the current and (to some extent) previous data. The identification fitness is found for various configurations with different polynomial orders, and the best model fitness is obtained about 98% according to normalized root mean square criterion for a third order polynomial.

The renewable energy has a very important role in meeting energy needs. This is because the use of fuel for conventional power plants in the long term will deplete the dwindling resources of oil, gas and coal and can also cause environmental pollution. Solar panels based on 2N3055 transistors and Thermoelectric Cooler (TEC) are the basic materials for designing alternative power plants. In the manufacturing process, this solar panel utilizes electronic components that are capable of generating electrical energy (emf), so that it can be used as an appropriate technology to produce a solar panel that utilizes solar energy in the form of heat and solar radiation. The use of transistors 2N3055 and TEC proved to be more efficient in generating electrical energy, there was no significant decrease in voltage and current even though the weather was suddenly cloudy. The average voltage and current generated in this solar panel are 24.58 VDC and 2.72 Ampere DC.
