Abstract

In general, every company has the goal of increasing the value of the company by maximizing profitability. Many factors can affect a company's profitability, namely per-round cash, receivables, and inventory. Therefore, it is necessary to build an application-based system that is able to analyze the effect of cash, receivables, and inventory turnover on profitability in the company automatically and in real time. In this study, it uses the DEA (Data Envelopment Analysis) method which can be viewed as an operator of multiple linear regression, in addition to the software system development method used, namely RAD (Rapid Application Development). This application system can determine the outcome of a negative or positive influence on profitability based on the variables between cash turnover, receivables, and inventory. This research was conducted on cement companies listed on the Indonesia Stock Exchange between 2018 and 2020. The data obtained from the measurement results can be used as an analysis of the next program situation by using test analysis using SPSS on the running system and turning it into an automation and realtime system. This Application System is built using the PHP programming language, and the CodeIgniter framework and uses a MySQL database server.

Abstract

Ud. Melati Jaya is a Small and Medium Enterprise (UKM) engaged in processing ja-gung into animal feed. So far, the method of estimating raw material inventory has been UD's choice. Melati Jaya in the procurement of supplies, with the finished goods system has been ordered in advance by consumers so that there is no accumulation of finished goods in warehouses or pre-order systems, but in the process of fulfilling raw material inventories there are often delays due to shortages of raw materials in the market. This hampers the production process and if it occurs continuously will increase the chances of UD losses. Jasmine Jaya. In previous studies, it can be explained that the results of calculations in reducing UD inventory costs. Melati Jaya, specifically with a January demand supply of 73,993 kg, can be minimized with an optimal purchase of 16,058 kg with a frequency of 5 purchases per month and a safe supply of 2,963 kg. and place an order again when the quantity reaches 8,650 kg. The inventory cost that can be saved is Rp.17,504,704 using the EOQ (Economic Order Quantity) method which is a technique for procuring raw material inventory at a company according to the number of orders. But in the bookkeeping records of UD. Melati Jaya from February to March 2020 is still not good so there are some transactions that are not recorded properly, so the calculation results in that month are inefficient [1]. The purpose of this study is to find out how to control inventory using the collaboration of the EOQ and RAD (Rapid Application Develop-ment) methods as a technology implementation that will make it easier to analyze inventory in real time. The data analysis method used is a quantitative descriptive method. The data obtained from the measurement results can be used as an analysis of the next program situation by using test analysis using SPSS on the running system and turning it into an automation and realtime system. This Application System is built using the PHP programming language, and the CodeIgniter framework and uses a MySQL database server.

Abstract

Employees are company assets because their role determines whether the company succeeds in achieving its goals. In acquiring employees who perform well the company must hold the implementation of training, which serves to improve the ability of employees to work. This research was conducted on employees of the Directorate of Human Resources and General Affairs of PT Pelindo 1 (Persero) Jl Krakatau Ujung, Medan. Referring to this, training data collection is also carried out manually using ms excel which is considered still ineffective because they have to look at the data to one source of training organizers, namely the Corporate University Division so that if there are employees who are in branches outside the city they will find it difficult to see what training they will get, there is a system that can make it easier for employees to see their own training data online. The system uses a MySQL Database with 11 tables and also uses the CodeIgniter Framework and php programming language. The training data displayed using Bootstrap to speed up and facilitate website development, to be able to see the existing training data users must enter the training data feature first and search according to the name, year or branch.

Abstract

The door security system using RFID is one of the many systems that can be used to increase the level of security on the doors of houses, classrooms, warehouses and so on. The door security system uses RFID as a medium to read or identify so that the door can open. It uses a relay as a link and breaker of electric current that is flowed to the load (Solenoid Door Lock). It uses LCD as a notification whether RFID successfully identifies what not. When RFID identifies the card and the condition of the card that the RFID reads successfully then the LCD will pop up the text "WELCOME LAB IOT" and the Solenoid will open. After a few seconds then the solenoid will lock again. Conversely, When RFID identifies the card and the condition of the card read RFID is not successfully detected then the LCD will pop up the text "PLEASE TRY AGAIN" and the Solenoid will remain locked. If during the RFID card reading process there is a failure 3 times, the Buzzer will sound and the LCD will display the text "YOU ARE NOT REGISTERED".

Abstract

The purpose of this study is to simplify the process of creating a weblog and provide solutions to compatibility problems in standalone applications. HTML5 is the latest web technology that continues to be developed and will soon be the successor of the previous generation of HTML. The web-based presentation creation service in question will utilize HTML5 and JavaScript features to present a user-friendly web-based application, with an emphasis on receiving input in the form of text and managing it into a web 2.0-based responsive blog. This web2.0 blog based on HTML 5 and CSS 3 provides a presentation creation interface with features such as automatic audio and video player without having to add additional plugins. In addition, this blog simplifies in the creation of coding.

Abstract

Heart rate / pulse is an important indication in the field of health which is useful as an effective and fast evaluation material and serves to determine the health condition of a person's body. The method of measuring the number of pulses has been used by doctors to determine stress, in this day and age there are still many pulses checked and analyzed manually with the help of a doctor or nurse to be able to find out the condition of the pulse when examined. It is very troublesome if only to check the pulse should require the help of a doctor or nurse. Therefore, the design of a portable heart rate device can replace the performance of a doctor or nurse manually, so that the pulse checker can be monitored by himself using a sensor attached to the finger to help analyze the pulse, so that the results can be known by the examiner by looking directly from the LCD. With the current conditions, the role of experts is so important, so the development of modern tools, especially in biomedical matters for various kinds of diagnoses with the help of tools, can make it easier for examiners to check the condition of their pulse with technology that is increasingly developing at this time. The final project this time aims to develop existing technology with the help of pulse sensors as an analysis medium by connecting them to a microcontroller as a voltage source, as a tool that can analyze the pulse, so from the design of this tool can later help the examiner analyze the condition himself by attaching the sensor to the surface of the finger. With the difference in age in each person, the condition before activity is obtained, which is in the range of 60-100 bpm, as for the difference in test results both before and after the activity depends on the seriousness of the person doing activities.
