Abstract

The car continues to develop the technology for the sake of convenience for the user to get a car. Currently the cars already provide many services, including : features - features, the fuelefficient, environmentally friendly, and safety while driving. But comfort when driving on the road is still not perceived as bottlenecks that often occur. Cars are often stuck in traffic will experience a diecasting machine, because the machine lights up constantly - constantly in a state of standstill. Researchers of this problem offers solutions in the field of transport. Researchers create “Design of Aero Anti-Gravity Car Microcontroller-based dsPIC30F”. It was inspired from a means of transportation that can resist the force of gravity, among others : airplanes, helicopters, jets and rockets. So that the principle of work on the Anti-Gravity Car’s is the aerodynamic system of microcontroller-based dsPIC30F. Keywords : Aero Anti-grvitasi Car, DSPIC30F.Aerodynamic

Abstract

 The right use of rain can provide many benefits. For this reason, mapping of rainfall areas is needed. This is intended to determine the level of disaster preparedness for each region. In mapping, a tool is needed to calculate the rainfall that falls. In the market there are only manual measuring devices, while rainfall gauges are not available which can measure automatically and directly but additional equipment is needed separately. In addition, the measurement results cannot be seen by the public. Therefore we need a tool that works automatically that can display measurement results directly and can be seen directly by the public. Thus the community can see and measure rainfall that falls. In this plan Automatic Rain Recording is used by using a proximity sensor placed on top of a measuring cup and the sensor is connected to the AVR128 Development Board as the control center to convert sensor data into ADC (Analog to Digital Converter) data. This tool is connected with a microSD with a capacity of 8Gbyte to store rainfall level data. AVR128 will store every 2 minutes with a total of 275,368 data and 382 days of storage capability.Keywords : rainfall, ARR, ADC, AVR128, mikroSD

Abstract

Induction motors are widely used in the industrial world because they have many advantages, including construction that is very simple and strong, cheap, has high efficiency, quite good power factor, and maintenance is easier. Besides the advantages of induction motors also have weaknesses, one of the disadvantages of an induction motor is not being able to maintain its speed constantly if there is a change in load. If there is a change in load, the speed of the induction motor will decrease. One method of regulating the speed of an induction motor developed in addition to vector control is the Direct Torque Control (DTC) method. The DTC control technique allows direct and separate flux and torque settings and can be done without using a speed sensor. The estimated rotor rotation, torque and flux is carried out by the DTC which is inputted with stator voltage and current. To achieve the desired flux and torque estimation is used as feedback on the control system. In this final assignment, the speed regulation of the induction motor will be simulated using the DTC method using Matlab. The results obtained through the simulation show the length of time to reach the reference speed for speeds of 500rpm and 1000 rpm is around 0.5 seconds. Keywords : Induction motor, Direct Torque Control, Matlab.

Abstract

 MCE Building Sultan Agung Islamic Hospital Semarang is a public facility that requires an electrical installation system that is in accordance with PUIL 2000. The purpose of evaluating electrical installations at the Multi Center of Excellent (MCE) building in Sultan Agung Semarang Islamic Hospital is to find out electrical installations in accordance with PUIL 2000 Evaluation of electrical installations includes calculation of MCB security and calculation of cable size. Calculation using manual calculation method and calculation using Ecodial Calculation 4.7 software. The calculation results are then compared to the installed units. From the results of the comparison it can be seen whether the electrical installation is in accordance with PUIL 2000. The results of the analysis can be concluded that the electrical installation system in the MCE building of Sultan Agung Semarang Islamic Hospital is in good condition and safe. In MCB installed units, they are in accordance with the PUIL 2000 standard. In the cable sizes installed several are in a condition not in accordance with the PUIL 2000 standard so cable replacement is required. For example, on the 1st floor divider panel SDP cable where the installed cable is 4x35 mm2, it is replaced by 4x95 mm2.Keywords: Evaluation of Electrical Installation, PUIL 2000, Ecodial Advance Calculation 4
