Abstract

Communication, discussion, and file sharing between divisions in a company is something every employee often does. The problem in this research is that not all users are connected smoothly so that it hinders communication and file transfers and in communication between divisions they have to install various applications on cellphones and PC users. This reduces the duration of time and efficiency in work. To solve this problem, a web-based chat application was designed. Because the development of these applications must use a good and structured design. Web-based chat application was created to solve this problem. This web-based application can be accessed via a web browser without having to install the application on a cellphone or laptop user. Based on the design of a web-based chat application that has been created, it is expected to be a solution for discussing, communicating and sharing files between employees in a company. In addition, it is useful to keep in touch and share files without having to install applications on cellphone or laptop users. The result of this research is that this web-based chat application can be a solution to keep communicating between employees who have difficulty accessing the internet.

Abstract

Service activities carried out by the Academic and Student Administration Bureau (BAAK) STMIK Widuri for students who will carry out field placement program (KKP) are currently still carried out conventionally, this makes the process of making KKP cover letters and also assignments for supervisors takes time, which is quite long and less efficient. To overcome these problems, it is necessary to create a web-based application system that can simplify and speed up the activities of student KKP administration services. In this study, observations were made on the current system modeled using Business Process Modeling Notation (BPMN) and Data Flow Diagrams (DFD). The problem analysis process uses the Root Cause Analysis (RCA) method. The system design runs with UML diagrams, namely Use Case, Activity and Deployment Diagrams. Making a prototype with a high fidelity concept using the PHP programming language, HTML 5, CSS, jQuery, Bootstrap and DataTables frameworks and the Chart.js library. This research resulted in a prototype that describes the overall functionality of the Online MPA system, interactive and has an attractive interface.

Abstract

Entering the digital era and the rapid development of technology, the existence of technology is now increasingly advanced and affordable to make it easier for humans to carry out various activities. Now humans can be helped well in carrying out various activities such as selecting the Chairperson of the Student Executive Board (BEM) using e-voting. The problem in this research is that the election of the head of the BEM still uses a simple information delivery medium, namely in the form of sheets of paper for sending the vision and mission and also for selecting candidates. This of course becomes less than optimal and less efficient, especially in the Covid-19 pandemic situation which requires 98 percent of universities to implement distance learning. The purpose of this research is to create an E-Voting-Based BEM Chair Election system using the PHP programming language and MySql database. The method used is Create, Read, Update, Delete (CRUD). As a result, this system will help universities to realize organizational digitization, especially at BRI Institute as a technology and business-based university.

Abstract

The clotheslines used by the community are still in manual form so people still have to lift the clothesline directly. People who have a lot of interests or who work will not have time to lift the clothesline directly so they have to leave their more important work. People are still confused about how to lift clotheslines with the uncertain weather when there are other jobs or traveling. Based on these problems, a prototype model of an automatic clothesline was built using an Android-based Arduino Uno, this is to lighten and shorten the time in lifting clotheslines or drying clothes when the weather is changing. The purpose of this research is to make a tool that can help reduce household chores, especially drying clothes automatically using LDR sensors and rain sensors and can be controlled by cellphones. An automatic clothesline tool has been designed using an Android-based Arduino. In making the prototype using the LDR sensor as a light detector, using a water/rain sensor as a rainwater detector and using a servo motor to open and close the clothesline roof, and use the HC-05 Bluetooth module to move the clothesline roof with a cellphone using bluetooth which is controlled with an Arduino microcontroller. UNO which functions as a data processing center. After testing this tool works well, the sensor will check the weather outside whether it is sunny or rainy. When the weather is sunny or hot outside, the roof of the clothesline will automatically open and if it is raining outside, the roof of the clothesline will automatically close. When the water sensor and LDR sensor do not work or experience problems, the automatic clothesline can be controlled with a smartphone that is connected to the HC-05 Bluetooth module. The result of this research is that the automatic clothes drying device using Arduino Uno can ease household chores when drying clothes and based on the test results with the blackbox table the tool runs 100% as desired.

Abstract

Currently, the monitoring system for leftover feed, feeding scheduling and water replacement at betta fish shelters is still human-oriented or can be said to be manual by going to fish shelters, then taking fish feed shelters and then sprinkling the fish feed using the hand of the fish owner himself into the fish shelter, at the same time seeing the last condition of the rest of the fish feed, besides replacing the water in the fish shelter, it is still done by manually moving the fish first to the reserve reservoir after that replacing the existing water in the fish tank. shelter used. Because the betta fish owners who have a lot of activities make the betta fish owners become disturbed in terms of feeding and water replacement in fish shelters that become irregular with a predetermined schedule, as well as monitoring the remaining fish feed in fish feed shelters. This can be an obstacle in the maintenance of betta fish which makes the development process of betta fish disturbed so that it can be one of the factors that cause betta fish to stress, get sick or even die. The prototype tool for monitoring feed, scheduling feed distribution and changing water in betta fish reservoirs using several tools, namely the Arduino Uno microcontroller, Servo motor actuator SG-90, mini submersible water pump, ultrasonic sensor HC-SR04, Blynk application which is used as a tool that can be controlled via a smartphone for automation of feeding, water replacement, in addition to monitoring the remaining fish feed in betta fish shelters.

Abstract

CV Digital Dimensi is a company engaged in the printing sector, which is a subsidiary of the XG Group located in Jakarta. In order to be able to compete with other companies, the company does not only focus on products and services but also efforts to build personal relationships with customers. Existing payment transaction data so far have not been utilized as much as possible in determining the company's business strategy, therefore the implementation of data mining is necessary to analyze and explore the available data to find new information that is more valuable and useful for the company. The K-Means Clustering method is a data mining technique to obtain data groups by maximizing the similarity of characteristics within the cluster and maximizing the differences between clusters. The purpose of this study is to apply the K-Means Clustering method to group sales transaction data on CV Digital Dimensi and display the results in the form of visual graphics using the Python programming language and Scikit-Learn library. The results of this study succeeded in classifying sales transaction data into five clusters and can be used as a reference in determining the company's business strategy.
