Abstract

Call center staff is a staff who works in providing repair services or service by telephone. This staff is in charge of explaining the solutions that will be carried out by the company in getting answers. Call center staff must have good manners and be smart. In getting good staff, companies can use a decision support system with the VIKOR method in determining and selecting these staff. Five criteria will be tested in determining the staff. The results of the VIKOR method can help companies in getting call center staff according to company expectations. The ranking results can determine the level of results from the VIKOR method test on call center staff who are used as candidates or alternatives. By applying this method, the search for call center staff will be better.

Abstract

The performance of a synchronous reluctance motor (SynRM) depends on the direct axis inductance (Ld) and the square axis inductance (Ld) of the machine. To achieve a high torque density and power factor, increasing the saliency ratio Ld/Lq and making this inductance difference (Ld-Lq) large enough is a well-known method. Otherwise, the performance of the motor will remain below that of a similar induction engine using a similar stator. This study attempts to place the right amount of permanent magnet in the rotor in the right position, it will be possible to achieve a significant increase in the performance of permanent magnet-assisted SynRM (PMa-SynRM) which will be comparable to an induction machine with the same stator. The PMa-SynRM will benefit from the reduction in price due to the use of a conventional induction machine stator.

Abstract

In Perwakilan BPKP Provinsi Riau, before official work travel, the officer needs to prepare some documents such as Assignment Letter and Cost Sheet, while the Administrator should make Official Work Travel Letter and Treasurer Accountability Report. To make all the documents the officer has to use other work unit application, and it needs some prodecures to be done that makes the process ineffective and inefficient. Other than that there is no application to monitor the budget yet. So we create a web based application that called Aplikasi Sistem Informasi Keuangan (ASIK) which use waterfall method. Result of the research is documents that needed in official travel can be made faster with ASIK so performance of every officer can be more effective and efficient. Also, with ASIK, leader and administrator can monitor the budget easily.

Abstract

The development of motorcycle use in Indonesia is increasing every year. This increasing trend is also accompanied by the increasing number of theft crimes of motorcycles. This is due to the physical nature of the motorcycle which is relatively small and easy to steal. In this study the author will discuss the motorcycle theft prevention system by installing various sensors built using fuzzy logic and utilizing the concept of the Internet of Things (IOT). This fuzzy logic consists of values and domains that are classified into several variables to conclude the degree and status of the motorcycle as an alarm trigger. Then by utilizing IOT the alarm is converted into a notification that will be sent via the motorcycle user's Telegram application if the motorcycle is stationary, Bergerak or moved. This system has 2 (two) components, namely hardware in the form of several sensors including infrared sensors along with a microcontroller and software connected to the Telegram application which functions as a motorcycle status notification receiver.

Abstract

The number of beauty and care products is widespread outside, the more skin problems people experience . Various problems of this disease are also caused by allergies due to the use of various beauty products and taking care of the skin from products on the market . Therefore, we need a system that can help choose good skincare according to skin type using the Analytical Hierarchy Process (AHP) method. The application that will be made for the selection of facial foam, moisturizer, and mask with criteria, namely oily skin, normal skin, dry skin, sensitive skin and combination skin, this application is expected to solve the problem of choosing skincare more effectively and precisely. The application of this application uses a waterfall system development, built using the PHP programming language, and bootstrap as a tool interface design to make it look attractive k.

Abstract

This paper describes the main advantages of this DAS module which is that it can be manufactured at a very affordable price and provides good performance is commonly used in industrial control systems. Alternative data acquisition system (DAS) modules can use the LabVIEW interface in motor control systems. The DAS module is controlled by the ATmega64 AVR microcontroller which will communicate in both directions with LabVIEW using the serial communication method. Which is used to obtain 8-bit digital input, 8-bit digital output, 8 analog input channels, and also 2 analog output channels. Digital inputs can be used for 0-5V and 0-24V voltages. The digital output is made open collector with a "low" voltage of 0.276V. For analog input and analog output, this system has an average error of 14.47 in the input range of 1-5V; 72.34 for the 0-10V input range; 0.037 MA for 4-20mA input range, and 16.2 for the 0-10V output range. This system is not designed for use in applications that require real-time accuracy and fast accuracy

Abstract

The drive system is described in detail in this research, since it is the primary component in all circumstances and necessitates cooling machines in industry or at home to have a protection / safety system placed on the motor to prevent losses caused by probable disruptions. Cooling machines are becoming more common nowadays, and each cooling system must have an effective protective mechanism to ensure that the cooling machine's electric motor operates efficiently. Its purpose is to underline the important role of the electric motor protection system in order to guarantee that the engine coolant may be utilized safely and cost effectively for an extended length of time. In terms of electric motor management, safety is grouped into three categories: overload protection, short circuit protection, and short circuit protection and overload protection. Thus, to get the desired outcome, the safety of the electric motor functioning as a controller must be adjusted and thoroughly investigated.

Abstract

In this era of information households, electrical energy consumption is divided into two, namely the low economy class which consumes the most electricity, around 20.00%, and the upper-middle economic class which consumes the most electricity. about 20.00 to 32.00% ac. Vertical living is widespread in the middle economy class, with occupancy increasing by 9.52% in 2017. In this situation, an analysis of energy consumption and savings is required. The problem of the simple rental apartment case in Medan Asia Mega Mas Indonesia is a clear example of the need for an energy monitoring system. this is due to the use of electricity that is not by the function of the apartment, such as air conditioning and washing machines. Energy meter systems measure the voltage and current of electrical equipment connected to the system. the voltage sensor used is zmpt101b5 and the current sensor used is acs712. The design of this energy meter system can measure the voltage and current of electrical equipment with an error rate of 4.40%. according to the measurement results, the air conditioning system is the most power-consuming resource in the 800kwh range.
