Abstract

Business world, there are quite a lot of problems other than profitable income. Often there are errors in recording data that are the source of information from the business world. Likewise in the business world of a motorcycle repair shop, there are often errors in recording data both from the service or repair process and the sale of motorcycle spare parts and accessories. In the motorcycle repair shop business, errors often occur in recording spare part and accessory inventory because of the many types of spare parts and accessories. In addition, there are also several errors in calculating the total amount that must be paid by customers because they still use manual calculations as well as in refunds. Seeing these problems, an information system is needed that can overcome this problem, so an information system will be built by utilizing information technology both in terms of hardware and software that carries ease of use / user friendly. This Motorcycle Repair Shop Information System Application will be implemented with MySQL as a database and Java Netbeans as software and using the SDLC method in designing the information system. MySQL database and Java Netbeans are software that can be implemented in several operating systems such as Microsoft Windows, MacOS and Linux so they are not limited to just one operating system. Conclusions that can be obtained from the result of tcreating a Motorcycle Information System Application has provided convenience to employees in entering data in the form of spare part data, customer data or transactions so that errors in calculating the total amount to be paid by customers can be overcome because with this Motorcycle Workshop Information System Application all calculations are done automatically so that employees no longer experience difficulties or make errors in calculating the total amount. This application provides convenience and reduces errors that are commonly made by employees

Abstract

Pulmonary tuberculosis (TB) is an infectious disease that attacks the lungs and is caused by the bacterium Mycobacterium tuberculosis. The GeneXpert RT-PCR examination (Xpert MTB / RIF) is a development of a diagnostic tool that can automatically detect the presence of Mycobacterium tuberculosis (MTB) by molecular examination and can be used to detect MTB resistance to rifampicin. Erythrocyte sedimentation rate (ESR) is a test used to determine the rate at which erythrocytes settle in the blood. The purpose of this study was to determine the relationship between GeneXpert RT-PCR results and ESR in suspected tuberculosis patients. This research uses a cross-sectional study. The sample used in this study were 56 new suspected TB patients who had never been treated for ATD and underwent GeneXpert RT-PCR examination. Sampling was carried out by purposive sampling with the TCM Rif Sen group and negative results. A total of 27 patients (96.4%) with Rif Sen's GeneXpert RT-PCR results had high ESR values. 15 patients (53.6%) with negative GeneXpert RT-PCR results had normal ESR values. The results of the Chi Square test (X2) show that p-value = 0.000 OR = 0.032. There is a significant relationship between GeneXpert and ESR values ​​in suspected tuberculosis

Abstract

A battery is a device that stores power in an Uninterruptible Power Supply (UPS) system. The most common type of UPS battery found today is Valve Regulated Lead Acid (VRLA). So that the UPS can work optimally according to its capacity and backup time, it is necessary to determine the battery capacity. In this research, the capacity of the VRLA battery on a particular UPS was determined based on direct testing and based on calculations. VRLA battery capacity calculations refer to the UPS and battery datasheet. The calculation stage starts from calculating the current and battery power used according to the load power absorbed by the UPS and referring to the table of constant current discharge and constant power discharge characteristics. Determining battery capacity based on testing is done by measuring the backup time of the UPS. The calculation results and test results directly show that there is a difference in backup time because the battery used is an old stock battery. The research results also prove that determining battery capacity by calculation can ensure that the battery capacity is more appropriate or not too large so it is more economical.

Abstract

Jatuh tegangan pada jaringan tegangan menengah merupakan suatu kondisi jumlah tegangan yang disalurkan tidak sama dengan tegangan yang diterima. Jatuh tegangan juga dipengaruhi oleh arus yang mengalir dan nilai resistansi dan reaktansi penghantar. Penyulang Subaru merupakan salah satu penyulang pada Gardu Induk Kenten yang mempunyai beban besar sehingga saat beban puncak, jatuh tegangannya cukup besar. Tujuan dari penelitian ini adalah untuk menganalisa jatuh tegangan pada Penyulang Subaru, ditinjau dari sebelum pemecahan beban dan setelah pemecahan beban pada saat beban puncak. Metode yang digunakan dalam penelitian ini adalah metode topologi jaringan. Hasil penelitian adalah sebelum pemecahan beban, jatuh tegangan 3 fasa pada Penyulang Subaru adalah 287,3229 V atau 1,4154%. Setelah pemecahan beban, jatuh tegangan 3 fasa pada Penyulang Subaru menjadi 109,1823 V atau 0,5300%, dan jatuh tegangan 3 fasa pada Penyulang Chevrolet menjadi 109,2697 V atau 0,5308%.

Abstract

Technological developments make it possible to monitor electricity consumption in real-time via the internet. The system developed uses a power meter to collect data, Python to process data and IoT connectivity via NodeMCU ESP8266 to send data to the internet. Python is used so that measurement data can be processed and presented in an easy-to-understand format. The test results show that electrical data measurements can be displayed with an error ranging from 0.04% -11.56%. This is because there is a delay from the time the power meter is measured until the data is displayed on ThingSpeak.

Abstract

The Electrical Engineering study program of the Faculty of Engineering, Atma Jaya Catholic University of Indonesia has been collaborating with Harapan Bagi Bangsa Christian Middle School, Cilincing, North Jakarta for several years in an extracurricular program for junior high school students, as a form of community service from Electrical Engineering lecturers. The extracurricular activity program implemented is in the form of basic electronics training. The theme of the activity varies, according to the requests and needs of the partner schools. The first activity is to provide basic electronics skills training to students. This program received a very positive response from teachers and students. From the evaluation results of previous activities, all students wanted training activities with advanced materials. The training provided is an introduction to basic Arduino Uno microcontrollers using Tinkercad simulation software. The purpose of this activity is to conduct training on the introduction and how to program the Arduino Uno microcontroller to turn on Light Emitting Diodes (LEDs). The training was carried out at Harapan Bagi Bangsa Christian Middle School. The training began by assembling the resistor and LED components on the project board. After all the components were installed, an Arduino Uno microcontroller program was created to turn on the LEDs alternately according to the order of the program created. The training used Tinkercad simulation software and the Arduino Uno microcontroller board. From the results of the student evaluation, 92.2% of students gave good and excellent ratings, while 7.8% gave neutral ratings for this training.
