Abstract

This study applies data mining in determining recommendations for mustahik. The application is carried out using a classification method with an artificial neural network algorithm where the attributes used are age and type of work of the head of the family, the condition and ownership of the residence, the place of sewage, family monthly income, number of dependents, and diet. Tests are carried out using a combination of values ​​between learning rate, epoch, k-fold, and hidden layer neurons. Based on the test results from the classification process, it is found that the artificial neural network algorithm has the highest accuracy when the number of hidden layer neurons is six, the learning rate is one, the fold is seven, and the number of epochs is 200, which is 92.09%. The test results are then displayed on the Mustahik information system page.

Abstract

The conventional question and answer method has limited time, space and level of understanding from each student so that it becomes an obstacle to the ineffective teaching and learning process. Global pandemic events that have a negative impact on the education sector. So that the teaching and learning process is temporarily stopped at school and diverted online. This study aims to produce a chatbot application as a media for distance learning that helps the teaching and learning process of teachers and students . In practice, This research uses telegram as a chatbot media. The method used for data collection is by interview, literature study, and observation. Testing will be carried out with a black box, calculation of accuracy, and a user acceptance test in the form of distributing questionnaires. The results of this study produce a Chatbot Application as an E-Learning Media for Students that can help teachers in providing distance learning to students efficiently and easily.

Abstract

QR stands for Quick Response, which is in accordance with its purpose is to convey information quickly and get a fast response as well. In contrast to barcodes which are only able to store information horizontally, QR codes are able to store information both horizontally and vertically. So that automatically QR codes have the ability to store more data than barcodes. QR codes can be used in the inventory system at the State Polytechnic of Ujung Padang to make it easier to read inventory data.In this study, the author will create an inventory system using a QR Code. The inventory system will be made online so that it can make it easier for admins and staff to process data and present information. This system is made in PHP and uses  MySQL database for data storage, while the QR code is created using the Ciqrcode library. While in reading the QR code on the android application using the Zxing library. The inventory system built can make it easier to process inventory data and present information to the Accounting Unit at State Polytechnic of Ujung Padang.

Abstract

The Minasa Upa Village Office is a community service facility fulfilling population administration and licensing. Currently, the service applied is still carried out in a conventional way, which requires residents to come and queue at the village office to receive services. It is necessary to come to the village office to obtain information on the requirements for making a letter, to find out whether the submitted letter has been completed. Based on these problems, a system is needed to help services at the Minasa Upa Village Office be more practical and efficient. This study implemented an E-Government system that utilizes information technology in service. The e-Government implemented is in the form of an Android-based application designed using the Java programming language and firebase as a database service. The application design method used is the System Development Life Cycle (SDLC) with a waterfall approach. The system testing technique used is black box testing which consists of two stages, namely alpha and beta testing. The results indicate that the application is built according to the expected needs. This is proven through the tests that have been carried out. In addition, based on the questionnaire results, users stated that the interface of the application was easy to understand, with an average score of 86%.

Abstract

This study aims to destroy an automatic egg incubator, where the performance parameters to be monitored are the temperature and humidity of the incubator. The monitoring system uses the Internet of Things (IoT) application. The egg incubator utilizes the lamp's heat to maintain the room temperature's stability. Utilizing the DHT11 sensor, the temperature data will be processed on the Wemos d1 microcontroller, which is then sent to the internet wirelessly. The temperature and humidity data results will be read in real-time using IoT with the Blynk platform, which can also be accessed using a smartphone. The results of this study apply IoT technology to the monitoring system for measuring conditions of the incubator temperature and humidity parameter values. All device modules will be packaged into embedded systems integrated with environmentally friendly IoT innovation rules and support the technological era of the industrial revolution 4.0. The results of measurements at the incubator's location and the monitoring using the Blynk application are relatively the same, and the success rate of hatching eggs reaches 74% of the total eggs put into the incubator
