Abstract

The emergence of Vehicular Ad-hoc Networks (VANETs) as part of the Intelligent Transportation Systems (ITS) technology development was expected to become an advanced method to solve the transportation system problem. The implementation of VANETs is expected to provide a new solution for traffic management strategy. Its main targets is to continue prioritizing traffic safety and to prevent the accidents on the roads. One of the VANETs problems before being implemented in the real world is the degree of freedom of the vehicle's mobility that limited by the road topologies. Various modellings and simulations have been performed to produce the most realistic mobility model. However, those models had become new paradigms due to various factors that limited them. The presence of the federated mobility model as an approach for traffic mobility modeling is considered to be able to provide more realistic and accurate VANETs simulation. Therefore, this article presents some brief reviews and contrast a number of the simulation and mobility models that have been used widely as compared to the federated mobility models that have developed until the present. The article's objective is to facilitate a better understanding of the traffic mobility modeling for the VANETs simulation that started from the interaction process until the integration between simulators. The understanding of the traffic mobility models will complement the knowledge that enable to perform the simulation of the VANETs implementation approaching the real conditions.

Abstract

This study discusses the design of arm robot model with 5 degree of freedom that is designed to be a small-scale model of the articulated robot industry to simulate the movement of the robots industry. The objective of this research is to build a real arm robot based on kinematic aspects with the movement of waist, shoulder, elbow, wrist pitch, wrist roll and gripper, and to analyze the robot movement. The design includes building the real arm robot based on Arduino Uno board controller and the movement of the robot using servo motor DC. The robot  can be controlled automatically from the computer with the RS-232 or USB port interface and it learns about the kinematic of the robot’s arm when an experiment on the forward kinematic is accomplished. The robot was running well, with the maximum distance that can be reached by the robot on the coordinate axis  x = 425 mm, y = 425 mm and  z = 480 mm.

Abstract

Harmonics are known as one of the causes of decline in the quality of the electrical power system, which can cause a negative impact on electronic equipment. Harmonics reduction that has been achieved with the passive filters is not quite satisfactory, thus development of active filters is required. This research proposes the use of parallel active filter design using a three-level inverter with the scheme of Fuzzy Logic Controller (FLC) that is used to reduce harmonics. The use of three stages Multilevel Inverter (MLI) on parallel active filter has several advantages that are lowering harmonic distortion and reducing stress switching. From the simulation results, it was obtained that three parallel active filters were capable of reducing the level of harmonic currents and voltages at the source; THDi before installation of the filter was equal to 26,16% and can be lowered to 2,42%. While THDv was reduced from 0,45% to 0,17%. Fifth-order harmonics is the most disturbing harmonic component, in which the value of IHDi beforeinstalling the filter is equal to 21,44% and reduce to 1,2% after the installation of the active filter.

Abstract

Radio Siaran FM merupakan salah satu teknologi telekomunikasi yang digunakan untuk memberikan layanan informasi dan hiburan bagi masyarakat. Untuk menjangkau masyarakat pendengar sebagai konsumen yang ditargetkan, kualitas penerimaan siaran menjadi hal yang sangat krusial. Daya pancar dan propagasi dari pemancar dapat mempengaruhi teknis kualitas layanan pada penerima. Masalah kualitas ini menjadi obyek yang dikaji dan pendekatan yang dilakukan untuk mendapatkan hasil, dilakukan pengukuran lapangan dengan menggunakan instrumen spectrum analyzer dan ditambah GPS sebagai penentu keakuratan lokasi pengukuran. Lima radio pemcancar swasta di kota Banda Aceh yang beroperasi pada frekuensi kerja 98,5 MHz hingga 103,6 MHz menjadi obyek penelitian dan akan dievaluasi. Hasil pengukuran lapangan didapati bahwa semua stasiun radio FM yang dievaluasi memenuhi standar kuat medan minimum yang diperbolehkan (Eμ) sesuai standar untuk kategori daerah rural, 54 dBμV/m  dan daerah urban, 66 dBμV/m. Hasil lain juga tidak ditemukan interferensi frekuensi dan semua stasiun masih dalam batas toleransi deviasi frekuensi kerja yang diizinkan. Dengan demikian, lima pemcancar radio FM yang dievaluasi mempunyai kualitas yang baik dan layanan yang diberikan dapat dinikmati dengan baik oleh pendengar.

Abstract

The utilization of micro hydropower plant is intended for providing electricity at Alue Dua village in North Aceh. A problem associated with the implementation of the micro-hydropower plant in the village is that the water flowrate of the run-of-river is varied at 117 litres per second during the wet season and at 36 litres per second during the dry season. This variation affects the speed of the water turbine and the capacity of power generated by its generator. Therefore to stabilize the output power and voltage of the generator during the course of the year, this paper aims to regulate the intake water flowing into the water turbine by controlling the opening vent valve from 0% up to 100% and controlling the electrical load connected to the generator. The speed of the water turbine was measured using the tachometer. It was found that the generator can produce electricity at its rated power 40 kVA during the wet season by opening the valve at 100% and at 12 kVA with the opening valve at 30% during the dry season. Opening the vent valve at 100% during the dry season can drain the water within 12 minutes
