Abstract

The lack of a disaster information system nowadays has made it difficult to find out information in the disaster area. Making information systems in disaster areas is important to solve the problem of uneven distribution of aid provided at each barrack. Because the conditions of each barrack are different, a system is needed to determine the priority for selecting disaster. To be able to determine the recommendations for the selection of disaster barracks, this study uses the Fuzzy Simple Additive Weighting (Fuzzy SAW) method, uses fuzzy method to determine the input basis value to SAW [3]. With the implementation of the Fuzzy SAW method, the results of this study can provide recommendations for Badan Penangguangan Bencan Daerah (BPBD) of Malang to determine the priority of disaster barracks that can take precedence.Keywords: disasters, fuzzy, information systems, priorities, simple additive weighting.

Abstract

The separation bearing controller (SBC) and separation-separation controller (SSC) approaches can be used to maintain multi-robot formation, while the Computed Torque Control (CTC) method is used to solve the dynamic problems of the robot. However, the SBC and SSC approaches combined with CTC cannot maintain multi-robot formation, if the leader or follower is disturbed. In this paper, the virtual structure method and the linear algebra approach added to the CTC method are used to maintain the triangular robot formation to follow the given trajectory. The simulation results show that the proposed control system design of multi-robots capable of following the trajectory and can maintain multi-robot formation with/without disturbance and noise.Keywords: computed torque control,  formation control, linear algebra, trajectory tracking, virtual structure.

Abstract

Traditional counter based digital Pulse Width Modulator (PWM) has been a straightforward architecture. However, realization of multichannel PWM with such design requires considerable logic gates. A novel architecture of multichannel PWM based on the usage of RAM block and frequency word accumulator is proposed. This architecture is capable of producing numerous channels while maintaining its performance. The design was tested in Microsemi SmartFusion A2F200 Customizable System on Chip, giving the result of 7.73% FPGA usage to produce 48 channels of 380Hz 16 bits PWM. The output performance for test application is acceptable. Keywords: PWM; RAM; accumulator; multichannel; digital

Abstract

High electric field intensity in string isolators can trigger corona which results in premature aging of the insulator. One solution to overcome this problem is by installing the corona ring, the corona ring will uniform the electric field distribution of the insulator adjacent to the conductor. However, the dimensions and placement of the corona ring will affect the performance of the corona ring in distributing the electric field. therefore, this study will discuss the effect of dimensions and placement of the corona ring on the electric field distribution. Parameters observed were ring length, ring angle and height of corona ring. Simulation with the finite element method (FEM) is used to model the electric field distribution value for each parameter change. As a comparison, changes in corona ring parameters compared to the corona ring design are commonly used in 500 kv gantry substation in Indonesia. Keywords: Corona ring, Electric field distribution, Finite element method (FEM), Insulator string, Porcelain Insulator.

Abstract

The humanoid robot is a robot which has humanlikeshapes and/or functions. For instance, a humanoid robot hasa neck that connect the head to the body, two legs to supportthe body, and has two arms on the right- and left-side of itsbody. According to the RoboCup competition, the humanoid robotcan be classified into several types based on their sizes, i.e.,kid-size, teen-size, and adult-size. In this study, we developeda teen-size humanoid robot with the aim of approaching thesize of children’s bodies with autism to facilitate the interactionsbetween the robot and the children. In general, the autism personis difficult to communicate with a normal person because there isa virtual wall that limits the world of the autism with the normalperson. As long as the wall is standing upright, communicationwill be difficult, so that inconvenience occurred on both sides.Especially in children, the process learning will be hampered ifcommunication is blocked. In many cases, the autism childrenmore actively interact and/or communicate with objects such asbooks, toys, and so forth. This motivated us to use a humanoidrobot as a mediator of interactions and/or communication withthe autism to support their therapy. Of course the choice ofhumanoid robots must also be considered both financially andfunctionally. At present there are many commercial humanoidrobots such as: NAO, Darwin-OP, and so forth. However, theprice offered is relatively expensive and also inflexible capabilitiesbecause existing hardware and software can no longer be freelydeveloped. Flexibility in hardware and software is very importantfor the implementation of a system that can be used in supportingthe therapy for autism. These facts motivated us to develop theIchiro teen-size robot. In this study, we developed a therapy forautism in the form of movement by humanoid robots such asa gymnastic movement. The movement is expected to be ableto be followed by the autism and has a positive impact ontherapy. One of the advantages of this study is being able toadd robot movement flexibly, so that the movements suggestedby psychiatrists should be able to be implemented and help tosupport the autism.Keywords: humanoid robots, RoboCup, robot's movements, therapy for children autisms.

Abstract

Induction motor is one type of electric machine that is widely used both in household consumers and industrial players. However, induction motors have drawbacks, namely starting currents that can reach 5-7 times the nominal current, of course this can lead to reduced life time of other electrical equipment and the possibility of shutdown or trip is very large. This research proposes a new modeling to create a soft starting system to reduce the 3 phase induction motor start current. This system was built with the help of a Phase Delay Control power electronics circuit with the main component, Triac, which functions to regulate the input voltage of a 3 phase induction motor and a contactor whose function is to move the 3 phase induction motor power supply from the soft starting system to the PLN source directly if, The input voltage is the same as the nominal voltage. The output of these processes is the Triac ignition angle, so during the starting process, the induction motor will receive an input voltage in stages from the smallest to reach its nominal voltage. Thus the results of testing the soft starting system that is designed to have a maximum current value at the start of 2.45 A or 77.58% lower than the start current using the DOL method with a value of 10.93 A at no-load conditions and 7.41 A or 34.19% lower than the motor starting current with the DOL method with a value of 11.31 A when the motor is loaded.Keywords: phase delay control, soft starting, three phase induction motor.

Abstract

DC motor speed regulation is an important role in the industrial process so it can run easily and efficiently. A good DC motor speed control system must have a fast and accurate response. However, it is rare to find a DC motor that has controlled to get a constant speed. This research presents an analytical comparison of PI controller and Fuzzy Logic Controller for Speed Control of DC Shunt Motor. The disadvantages of PI controller like it do not operate properly when the system has a high degree of load disturbances [1]. FLC is a good for load disturbances and can be easily implemented. The simulation of both speed controller have been made by Matlab Simulink software.Keywords: DC shunt motor, fuzzy logic control, matlab, PI control, simulink.

Abstract

Vehicle Routing Problem is an issue in item delivery from depot to its customers using several vehicles which have limited capacity with a purpose to minimize transportation cost. The packing constraints exist because the vehicles which are usually used in item delivery have rectangular-box shaped container. Also, the items are commonly in shape of rectangular-box. Therefore, packing or loading method is needed so that containers could load all of the items without causing damage and could ease unloading process. The purpose of this final project is to develop a model and algorithm using metaheuristics method, especially genetics algorithm in order to minimize total delivery distance. A hybrid genetics algorithm and bottom-left fill algorithm also take place to solve the packing process. This algorithm delivered average solution 0.08% worse than ant colony optimization, but had 2.93% better solution than tabu search. Keywords: Routing, Optimization, Genetics Algorithm, Packing, Bottom-Left Fill

Abstract

In rural and isolated island, electric power on the island as an off-grid system is typically supplied by diesel generators (DGs) and Solar Power Plant. The paper proposes options to maximize PV penetration in the hybrid system with minimum modification to the existing system. Modified HOMER simulation modeling is used to mimic the behavior of hybrid PV-Diesel controller. Existing DGs configuration and current load profile shall be taken into account in these options. Maximized PV penetration will decrease fossil fuel dependency, lower LCOE, reduce carbon emission and further support the government's National Energy Policy (NEP) program in renewable energy. Keywords: Microgrid, Smartgrid, HOMER, Photovoltaic, Diesel, Hybrid, Solar Power Plant, Renewable Energy
