Therefore we need a system that makes it easy for users to meet the information needs needed by building a digital dictionary application related to computer terms and informatics by utilizing the search engine features in it. Search activities are carried out daily to meet information needs. However, an error that is often unavoidable in performing a search is a typing error in the query. As a result, the information sought is not as expected. Based on this, we need a system that can identify typographical errors in the search text. So in this research, a website-based dictionary of computer and informatics terms will be developed by applying Peter Norvig's spelling corrector using the Python language with the flask framework. The implementation results show that Peter Norvig's spelling corrector method can be applied to computer and informatics term dictionary applications. This can be seen at the level of accuracy reaching 89% in correcting 180 word variations that contain typographical errors based on the highest probability of each possible word in the corpus. However, there is a lack of this spelling corrector method, it is still difficult to overcome typos in spelling abbreviations and typographical errors that exceed 1 letter</p> 2023-01-30T00:00:00+00:00 Copyright (c) 2023 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika PERBANDINGAN KINERJA KLASIFIKASI SENTIMEN ULASAN PRODUK PEMBELIAN BERAS DI MARKETPLACE SHOPEE 2022-11-17T03:50:33+00:00 Dedy Sugiarto Syandra Sari Anung Barlianto Ariwibowo Fitria Nabilah Putri Dimmas Mulya Tasya Aulia Arviandri Naufal Zaki <p>This study aims to compare the performance of product purchase sentiment classification in market place shopee using four classification algorithms, namely support vector machine (SVM), naïve bayes (NB), logistic regression (LR), k-nearest neighbor (KNN) and associated with the feature extraction model used, namely term frequency - inverse document. frequency (TF-IDF) and bag of word (BOW). Data collection was carried out by extracting rice product review data through the Shopee website using a web scraping technique which was then saved in the form of a file with CSV format. The number of product reviews obtained is 3531 reviews and after pre-processing through the elimination of duplicate reviews, there are 464 reviews with details 16.17% having a negative label (rating 1 or 2), 15.52% having a neutral label (rating 3), and 68.32% have a positive label (rating 4 or 5). The composition of the rankings shows that the data is not balanced. The experimental results show that the combination of LR with TF-IDF shows the best performance with an accuracy of 80%.</p> 2023-01-30T00:00:00+00:00 Copyright (c) 2023 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika PERANCANGAN APLIKASI AKADEMIS BERBASIS ANDROID PADA SMP KARTIKA XI DI JAKARTA TIMUR 2023-01-12T01:04:20+00:00 Taufiq Septryana Yuli Haryanto Andi Prastomo <p>SMP Kartika XI is one of the educational entities that is obliged to carry out academic activities.

One of the products born of block chain technology is cryptocurrency. Cryptocurrency is a digital currency that has the main characteristic of being transparent because it is a public ledger, all transactions are recorded online so that anyone can see where and where the coins are flowing from and where. To assist in the process of trading, an application is needed that can automatically carry out trading activities. The application that was built as a solution to this is a crypto marketplace website using the waterfall method in system design, starting from analyzing software needs, design, implementation, and testing. The results show that this system has successfully implemented the Indodax API which is used to see prices and other information about the bitcoin market and can buy and sell bitcoin ups and downs in crypto prices in the market, and can see information in the form of market activities, BTC / IDR market charts, and can even see transaction history.&nbsp;&nbsp;</p> 2023-01-30T00:00:00+00:00 Copyright (c) 2023 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika RANCANG BANGUN PERMAINAN TRADISIONAL KALIMANTAN TENGAH BAGAPIT MENGGUNAKAN ALGORITMA ALPHA BETA DAN MTD(F) 2023-01-26T05:26:14+00:00 Ressa Priskila Putu Bagus Adidyana Anugrah Putra <p>Bagapit is a traditional game from Central Kalimantan. This game is usually done in free time or after doing daily tasks. This traditional game has begun to be forgotten, because of the rapid development of technology. In this day and age, people prefer to play games with gadgets. Therefore, to preserve and introduce this game to the wider community who are already familiar with technology, it is necessary to create a mobile-based bagapit game application. This game was made using the Multimedia Development Life Cycle (MDLC) method. This method consists of 6 stages, namely concept, design, collecting material, assembly, and testing. In this research, the system design is made by making use case diagrams, activity diagrams, storyboards, and User Interface designs. The material collected at the material collecting stage consists of background, object images, and audio. To determine the steps in the game, the Alpha Beta pruning algorithm and the MTD(f) algorithm are used. The making of this bagapit game uses the Godot Engine which uses the GDScript programming language. Testing is carried out using the black box testing method to ensure all functions in the game can function properly. This game consists of 3 levels that players can choose from. It is hoped that this game can introduce, provide insight, and preserve the bagapit game which is a traditional game typical of Central Kalimantan to the general public.</p> 2023-01-30T00:00:00+00:00 Copyright (c) 2023 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika SISTEM INFORMASI POINT OF SALE BERBASIS WEB PADA DISTRIBUTOR ALAT KESEHATAN 2023-01-26T05:21:50+00:00 Efrans Christian Widiatry Widiatry <table> <tbody> <tr> <td> <p>PT.

To be able to manage payment transactions for Education Development Contributions (SPP) better, it is necessary to build an Information System that can help manage data and transactions to be optimal. Therefore we need a payment information system that can facilitate SMA Negeri 1 Palangka Raya in dealing with the payment of tuition fees that are not yet optimal. In this study, a tuition payment information system was created that could be used for recording tuition data, cash, and non-cash payments, as well as informing parents/guardians of students about tuition payments and invoices. This study uses the Waterfall software development method which has stages of analysis, design, program code generation, testing, and maintenance. Non-cash payments and Whatsapp message delivery on applications use features on Midtrans and Whatsapp API. Unit testing is carried out using the Blackbox method. Based on the results of the research, it was found that this tuition payment information system could facilitate the school and students. The SPP Payment Information System is used as a means of managing SPP payment data for schools, non-cash SPP payments for parents, and information on SPP payments for both.</p> 2023-01-30T00:00:00+00:00 Copyright (c) 2023 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika
