Abstract

Elementary school is the starting place for a child to start education and get various kinds of experiences. Elementary school is the highest level of education compared to Junior High School and Senior High School. The large number of elementary schools makes parents/guardians not know for sure where the elementary school is located. This makes parents/guardians not have many references to send their children to school in the future. Based on the existing problems, the author proposes a web-based geographic information system that uses the A-Star Algorithm (A*) to be used as a means of information and also to add references to parents/guardians. The A-Star Algorithm (A*) is a method to search for information about the distance to reach the destination by selecting the closest route. The result of this research is a web-based geographic information system that can provide information about 6 samples of elementary schools along with the location and the closest route that can be passed in the Mustikajaya District area.

Abstract

The increase in data is very large, one of the sources comes from social media, especially Twitter which talks a lot about Covid-19 . The news through Twitter media regarding the impact of the Covid-19 virus is widely discussed because it causes unrest for the public which has led to the issuance of various government policies with the aim of preventing the spread of Covid-19 . Related to this, it is necessary to conduct a sentiment analysis of the text contained in the Twitter media. In this study, a sentiment analysis process was carried out related to public sentiment towards government policies during the Covid-19 pandemic in Indonesia on Twitter social media using the Naive Bayes Classifier method where the data used was classified into 2 sentiment values, namely positive and negative sentiment. The data used are 300 positive tweets data and 300 negative tweets data, where 80% of the total data is used as training data and 20% data is used as test data. Based on the test results, the data with a total of 120 tweets obtained the results of measuring the recall value of 93.33%, precision 93.33%, F-Score 93.33% and an average accuracy of 93.33%.

Abstract

Currently the rapid development of technology provides innovation, one of which is the technique of obtaining information from portal websites, termed web scrapers. This application provides data needs in the form of information where the process of retrieving information from sites will later be taken to observe behavior and perceptions to get the right segmentation. Most data collection is currently still done manually, as a result, this method has several system limitations, namely the length of the data collection process so that it slows down the performance of market segment analysis. The risk is not getting the right market segmentation. To solve this problem, a web scraping news site is needed. In this study, web scraping news sites were created using the python programming language and the flask library to display web scraping. In addition, the Selenium library is used to simplify application creation, facilitate interaction with the web and provide facilities to control a web browser. This program can retrieve data based on keywords, where the results are in the form of the title, posting date, summary, then collect the data that has been taken into a csv file extension automatically.

Abstract

UD. Rifar Jaya is a shop engaged in the sale of various kinds of drinks. In the sales process, UD. Rifar Jaya still uses a manual and simple system where the cashier still uses paper which will cause the evidence to be lost or damaged. During the process of checking the inventory items, they are still looking for one by one whose stock is out or only a little so that it will take a long time. The purpose of designing information systems for the purchase and sales of various beverages is to simplify the process of purchase and sales transactions in processing the data. The research method used is to collect some data including the method of observation, interviews, and literature studies to find out what problems are happening at UD. Rifar Jaya. The method of system development used is the waterfall method. With the creation of this desktop-based program, UD. Rifar Jaya is expected to be assisted in processing data on items, suppliers, customers, managing purchase and sales transactions, and making reports on items, purchases, and sales to be more effective and efficient.

Abstract

TB. Barokah Jaya Group is a business engaged in trading with its operational activities selling building goods. Inventory of goods plays a very important role in managing the inventory of goods in the warehouse, has problems in managing inventory because it is still using a manual system. Often occurs when checking goods and errors in recording incoming and outgoing goods reports. We need a web-based application as a solution to existing problems using the PHP programming language and codeigniter as a framework. To run the web server the author uses XAMPP. As a result, store owners can check the availability of goods without having to go to the warehouse and manage incoming and outgoing goods by inputting goods data into the application that the author made, so that the results obtained are faster and more accurate

Abstract

The library is a place where information can be obtained easily. Because in the library there are lots of books, journals, and research results that can be used. As is the case in the library of SMAN 1 Babelan. But in fact the library of SMAN 1 Babelan still has not implemented a digital technology information system. So that in the recording process, they still use a manual system or recording in a ledger. Therefore, a system is needed to overcome this problem by implementing the Knuth-Morris-Pratt algorithm which is a string search algorithm, and the Waterfall search development method.

Abstract

SMKIT Nurul Qolbi uses the internet as a means of promotion, marketing, learning and practical communication to teachers, students, and school employees. But the SMKIT Nurul Qolbi network has not implemented hotspot network security in sharing and managing internet connections to teachers, students, and school staff computers. Without hotspot network security, many computers use the internet irregularly, causing other computers to not get a fair share of internet access. Due to the uneven internet connection, this causes disruption of school operations, so that it has an impact on the school's losses, both material and managerial. The absence of hotspot network security at SMKIT Nurul Qolbi is exacerbated by the large number of teachers, students, and school employees who do not use the internet to access needs related to work and learning. There are still many teachers, students, and school employees who use the internet to access social media sites such as Facebook, Twitter, and other sites that have nothing to do with work and learning, making the hotspot internet ineffective at Nurul Qolbi's SMKIT. Therefore, to maximize internet access found at SMKIT Nurul Qolbi, hotspot network security is needed. With hotspot network security, it is hoped that all computers can use the internet smoothly and stably even though all computer units use the internet at the same time and with hotspot network security it is hoped that it can increase the productivity of teachers, students and school employees.

Abstract

Pharmacy is a means of pharmacy practice services carried out by pharmatics. Pharmatices provide various kinds of medicines that can be thought and sold with prescription and non-prescription. The purpose of this research is to ease the work of managing incoming and outgoing data from drug sales The medicines provided by pharmacies are certainly not small and will take a lot of time if the sales process and recording information still uses simple methods such as writing on a book. As is the case with the Diana pharmacy, in recording information still uses simple methods such as writing on a book. As is the case with the Diana Pharmacy, in recording drug information, they still use this method. This is course of outdated because it has now entered an era of increasingly sophisticated technology. Therefore, Diana Pharmacy requires an information system to overcome these problems and the application of the Horspool algorithm, namely string search and with the waterfall development method in the development of information systems.
