Abstract

Long Term Evolution (LTE) refers to state of the art of technology in mobile telecommunication. It has an uplink capacity up to 50 megabits per second (Mbps), and 100 Mbps of the downlink. The purpose of this study is to provide information on the development of LTE in Makassar, and provide information on the LTE network optimization capacity for data access fulfillment in Makassar. This research was conducted from October 2015 until January 2016. The location of the research was conducted in one of telecommunication provider service provider company in Makassar, Telkomsel Tbk, which inaugurated LTE service in Makassar Commercial. As for technical aspect which is needed to determine area coverage is the width of the predetermined area. Makassar city has awidth of 175,77 km2 and comprises of 14 districts. Each cell coverage of the LTE design is 2,33

Abstract

this final duty have been done [by] system development of Pengontrolan speed of Motor Induce Three Phase use pengontrolan conduct resistor base on PLC. System the controlled [is] speed of Motor Induce Three Phase [pass/through] resistor kontroler by using kontaktor kordinasi with resistor. Arrangement of torque [at] Motor Induction will be more easy to and way of this have been developed [by] [in] some weakness literature,namun of Motor Induce [is] unable to maintain its speed constantly if/when happened change of and also speed of torsi burden. Hence to get constant speed and also improve;repair Motor Induction performance made [by] method of kordinasi kontaktor with resistor that is a[n method arrangement of torsi [at] Motor of Induksi.Penelitian this aim to to  Design system of Pengontrolan MI3F With Three Speed. Object Research in the form of appliance for the scheme of system pengentrolan of Motor Induce Three Phase by 3 speed being based on PLC. Scheme of system pengontrolan of MI3F base on this PLC give method three kcepaatan with aim to for the efektifitas of usage of motor with model three speed. Induction motor can be arranged [by] its speed with three phase that is 500 , 1000, and 1500 rpm.

Abstract

 Short duration under voltage or what is known as voltage sag or dip voltage is a decrease in the amount of supply followed by a recovery after a short period of time of failure. Referring to the IEEE 1159-1995 standard, the voltage dip is defined as the rms voltage drop of 10% - 90% for the amplitude value for 0.5 cycles to less than one minute. This study aims to determine an overview of the switching effect of the smelter in the 150 kV high voltage overhead line system (SUTT) in the South Sulawesi electrical system. The results of the analysis with the help of ATP software show that the sulsel system is still in a safe condition because the voltage drop and magnitude that occur are still within tolerance limits.

Abstract

This study aims to: (1) To Set the DC motor rotation with input DAC using Matlab, (2) To produce a data acquisition system with a portable hardware. The tools are designed in the form of a regulator and a DC motor drive with DAC input that can slow down and brought forward in accordance with the input value by utilizing PPI matlab program as a means of sending control signals to the DAC as a digital signal converter to analog signals. The software has been created in order pendekode decoding process runs efficiently when multiple application programs to access the system simultaneously. To allow users to access the system, the script code application program interface has been made in matlab language. The results of this study indicate that PPI and DAC capable of acquiring the data input mode minimum 60 bits (00.1111 million and 1.5625 volts) with a speed of 1066.41 rpm and a maximum input of 255 bits (11111111 and 4.9 Volt) with a speed of 922.852 rpm
