Abstract

At this time the development of science leads to the development of technology whose aim is to facilitate all activities and human work. In the medical field even the technology used is increasingly developing more practical, effective and efficient. In the medical world a physical examination or clinical examination is a process carried out by a medical expert to examine a patient's body so that it can find clinical signs of the disease. The use of technology in the medical field today requires a technology that can automatically record the condition of one's blood pressure and body temperature. With the technology that can automatically show the value of clinical examination results are expected to make it easier in the examination. By using NodeMCU which converts the voltage to a digital value and displays it on Android and the MPX5050DP sensor to measure blood pressure and the DS18B20 sensor to measure body temperature, the value sent by the sensor will be processed and displayed on Android. The measurement results are in the form of quantities corresponding to the measured unit such as mmHg (Millimeter of Mercury (Hydrargyrum)) for blood pressure and ˚C for temperature. Results are displayed on the android display. Tests on the device resulted in an error rate from the MPX5050DP sensor of 1.13% for systolic blood pressure, 0.95% for diastolic blood pressure, and at a temperature sensor of 0.5%.

Abstract

Resulting output voltage is not constant due to light intensity and surface temperature of the solar panels. To overcome the output voltage of solar panels that tends to fluctuate, is to add a DC-DC converter to the output side of the DC-DC Converter used in this study is the Quadratic Boost Converter type which has a role to increase the output voltage of the monocrystalline type solar panel so that it remains constant at 24V DC. using Mamdani Fuzzy Logic Control as a method of controlling PWM switching. The results obtained from this study are that the quadratic boost converter can keep the output voltage of the solar panel constant at 24V, with low ripple voltage and overshoot. The Mamdani fuzzy logic method used can produce a constant output voltage value with a rise time of ± 5 seconds. The efficiency obtained from this converter hardware is quite good, ranging from 76% - 88%.

Abstract

In office buildings, electrical energy is needed to meet the needs of lighting to electronic equipment used in the building. To support all of that, a reliable electrical installation system is needed so that all office activities can run well without causing significant problems. Therefore the planning of the electrical installation system in a building must refer to the applicable rules and regulations in accordance with PUIL and SNI. The design carried out refers to PUIL 2011, SNI 03-6575-2001 (Lighting System Design Procedures). The entire electrical installation system gets a 3 Phase supply from PLN. The total power in this building is 80000 watts, so the power needed from PLN to connect is 160 KVA. Conductors used in this installation, use cables with NYM and NYY types with varying sizes in accordance with the calculation of the conveying CRC that has been done.

Abstract

The application of the 3 phase induction motor is increasingly developing, this has led to research on speed regulation of 3 phase induction motors is also growing, because the use in industry and especially in hybrid vehicles is increasingly being developed. However, there are several disadvantages of an induction motor, one of which is the non-linear parameter characteristics, especially the rotor resistance, which varies in value for different operating conditions, so that it cannot maintain its speed constantly when a load changes. Therefore, to get constant speed and better system performance against load changes, a controller is needed. This study aims to implement the vector control method in the 3 phase induction motor speed control application in following the reference speed. In vector modeling, the 3 phase parameters (ia, ib and ic) will be transformed into direct quadrature (dq) parameters where in this parameter the setting of the field size and torque can be adjusted separately. In the implementation results, it can be seen that the use of vector control can be used as an approach in regulating the speed of an induction motor.

Abstract

Electricity has become a basic need for various human activities, because electricity has functions and benefits that are vital in daily life which has become a basic need in encouraging national development in all fields. One part of the world electricity is the installation of lighting that is also me njadi one of the main points in a building, it is very necessary that human activity has remained secure and running smoothly. In this study, the writer will design an electrical installation for a building, namely the office building of the Population and Family Planning Control Office (P2KB) of Central Sulawesi Province, JL. RA Kartini NO. 100 Palu City. This study aims to make an electrical installation design in accordance with the Indonesian National Standard (SNI) and the General Electrical Installation regulations (PUIL), so that the installation is designed to be more effective and efficient. In the design of this installation also made design drawings for installation in buildings. Based on the design planning of the electrical installation that has been done, the results are obtained, the total electrical power from the electrical installation of this building is 60246 watts or 75307 VA and for electricity supply is taken from PLN, namely 3-phase electricity with a capacity of 82,500 VA. The conductor used in this installation uses NYY and NYM cable types. The security used in this installation consists of 2 types, namely NFB and MCB , in addition to this building installation system is also given a PHB box to facilitate maintenance and repair in case of damage. Taking into account the economic and safety factors of the installation, the total Budget Plan (RAB) for the installation of the building of the Population and Family Planning Control Office (P2KB) is Rp. 223,600,000

Abstract

Power of energy generated from station is the some all the phase. The use of electricity as well as efforts to satisfy customers or consumers of electricity by optimizing the distribution network. By evaluating the distribution network of PT. PLN with the ODK (Open Data Kit) collect method will make it easier to take field samples, find out the long distance of the transformer point by making an arcgis simulation distribution map. After all the data is obtained then to find the voltage drop can be done by analyzing the length of the stretch, the power of the transformer so that it will be known what percentage of voltage drop in the location farthest from the power center.
