XYZ MENGGUNAKAN ALGORITMA APRIORI https://ejournal.upbatam.ac.id/index.php/jif/article/view/7354 <p><em>There was an error in the staff's recording of goods and calculations, making it difficult to locate the necessary data. A collection of data that has been recorded and calculated ultimately renders the data useless. The purpose of the study was to determine whether the RapidMiner application's use of data mining can aid in stock prediction and data analysis. For stock predictions, the researcher employs the a priori algorithm approach in this instance. The findings indicate that employees will request the most support in 2022—a printer—if they request a laptop by as much as 7.9%. The laptop category will dominate in 2021, and the PC category will dominate in 2022. Therefore, the highest level of confidence for 2022 is that employees will request a printer if they request a PC and an external hard disk of 100%. The conclusion states that employees can use the RapidMiner application to perform data mining by applying the a priori algorithm, which aids in data analysis and predicts employee supply requirements.</em></p> Nur Ikhsan, Fahmi Arzalega, Nur Nawaningtyas Pusparini Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7354 Tue, 05 Sep 2023 00:00:00 +0000 PERANCANGAN AUTOMATIC TEMPAT SAMPAH PADA SISTEM ARDUINO UNO R3 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7377 <p><em>Automatic Design of Trash Cans in the Arduino Uno R3 System is designed for waste management which is often a problem in many cities. Waste management is currently one of the factors that always influences the creation of a clean and healthy environment. Garbage that is always left alone over time will accumulate and pile up so that no one takes care of it, irregular waste is a problem that often occurs. In the waste collection process, which will be carried out by checking the garbage collection sites one by one, the work will be ineffective and inefficient, because it will take a lot of wasted time, even time and money. Furthermore, to simplify the waste disposal process, this can be done at any time, because the process is very easy and can be done or done by anyone. The result is that the ultrasonic sensor is used to capture objects or objects in front of it, then there is a servo motor that can move when someone throws trash, after that there is an LCD display that will display an inscription, after that there is also a mini speaker that makes a sound if someone has finished taking out the trash. So the conclusions that can be studied in this study are how to design an Automatic Trash Can on the Arduino Uno R3 System which can open the lid of the trash can by itself.</em></p> Tanto wijaya Tanto, Agus Salim , Nur Nawaningtyas Pusparini Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7377 Tue, 05 Sep 2023 00:00:00 +0000 RANCANG BANGUN APLIKASI TRACKING BERBASIS WEBSITE PADA PT ABCDE https://ejournal.upbatam.ac.id/index.php/jif/article/view/7386 <p>PT. ABCDE is a service company operating in the field of goods delivery and online purchases. Currently, PT. ABCDE aims to improve its services and quality standards in various aspects within the company, including the utilization of information technology. Currently, the existing services do not utilize a tracking application to obtain real-time information about the current location of the goods, causing a lack of transparency and inconsistencies in data across different departments. Additionally, the current process of generating delivery notes is manual, time-consuming, and leads to delays for drivers in delivering goods. Therefore, there is a need for a tracking application that records and displays real-time information about the current location of the goods, inputted by the drivers. Additionally, the application should automate the generation of delivery notes to reduce delays. This system will be designed using the PHP programming language and the Laravel framework, utilizing a MySQL server database that allows access from anywhere and anytime. The benefits obtained from this system include facilitating each department, especially the administrative team and owner, in checking the current location of the goods, and ensuring transparency of data across different departments to avoid any misinformation.</p> Akbar Bintang Izzulhaq, Ananda Azizul Akbar, Rizky Firman Setya Putra, Alif Firdiansyah; Endra Rahmawati Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7386 Tue, 05 Sep 2023 00:00:00 +0000 PEMETAAN PROSES BISNIS AS-IS DALAM MANAJEMEN LAYANAN TOEIC INSTITUSI VOKASI https://ejournal.upbatam.ac.id/index.php/jif/article/view/7405 <p>The Ministry of Communication and Informatics has established a Business Process Map for Ministry Level on Level zero (0) up to level 3 and this applies to organizations up to the work unit level.

Human resources can help create a positive work culture, increase productivity, increase employee satisfaction, and support company growth and innovation. The J&amp;T company is an 8-year-old shipping and logistics service company in Indonesia. Of course, employees have a lot of hope, especially in terms of welfare and transparency in the staffing system. Because this system is not yet computerized, it results in data recording errors, such as typing wrong numbers, ignoring data entry, or changing the position of numbers. Errors like this can cause inaccuracies in recorded data such as attendance, recording of overtime and others which result in recording errors in calculating employee salaries that are not appropriate. Therefore it is necessary to design a user interface and user experience to develop the application. The method used by researchers is the Human Centered Design method, which is an approach in which the system focuses on all forms of activities carried out by users and can identify what the user's needs are. This research is expected to create a solution by developing the needs of system users and creating a more modern and user friendly appearance when used by users.</p> Puspa Mayangsari, Mohammad Badrul Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7406 Tue, 05 Sep 2023 00:00:00 +0000 PERANCANGAN SISTEM INFORMASI ABSENSI FINGERPRINT BERBASIS WEBSITE PT.

To predict the election results, sentiment analysis methods can be used to evaluate public opinions through social media. One of the popular social media platforms nowadays is Twitter. As the Republic of Indonesia's Presidential Election approaches, there is an increasing number of tweets discussing the event. This situation creates a favorable opportunity to conduct sentiment analysis on the election campaign topic. There are various opinions from Twitter users with positive, neutral, and negative sentiments. The collected tweet data undergoes preprocessing, involving two main processes: cleaning and stemming. Therefore, sentiment analysis is necessary to understand the public's tendencies towards the election. The objective of this research is to obtain sentiment analysis of the text documents to determine positive or negative sentiments. Two methods, namely Random Forest and Lexion Based, are used to predict the presidential candidates' sentiments. Random Forest is employed to analyze sentiments in text data collected from various sources, including social media, news websites, and online forums. This method involves an ensemble of decision trees working collectively to classify sentiments as positive, negative, or neutral towards the Presidential Election candidates. On the other hand, Lexion Based is used to associate words in the text with specific sentiments.</p> Oktaviami Manullang, Cahyo Prianto, Nisa Hanum Harani Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7987 Tue, 05 Sep 2023 00:00:00 +0000 ANALISA DAN PERANCANGAN START-UP PEMESANAN JASA DESAIN GRAFIS BERBASIS APLIKASI MOBILE https://ejournal.upbatam.ac.id/index.php/jif/article/view/8016 <p>Graphic design is a visual form that uses images to convey information or messages as quickly as possible.

UIIAdmisi system is a web-based admission information system that is used to digitize the implementation of the student admissions program at the Islamic University of Indonesia. This system has been used by the organizers of the Indonesian Islamic University student admissions program from 2016. During its use period, new developers experienced difficulties in developing the back-end side of the UIIAdmisi system because the code in the system was difficult to understand. One of the reasons why the UIIAdmission system is difficult for new developers to understand is because UIIAdmisi solves complex business processes, but the system is built on a monolithic architecture which makes it the code to be bloated. For this reason, the UIIAdmisi system architecture migration process was carried out from monolithic to microservices by separating the existing components of the system into small independent components. These small components will communicate via the HTTP protocol with the implementation of the REST interface. The system will also be designed using the Domain Driven Design approach to make it easier for new developers to understand.</p> Muhammad Fachri Ramadhan, Zainudin Zukhri Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/8017 Tue, 05 Sep 2023 00:00:00 +0000 PERANCANGAN SISTEM INFORMASI COMPANY PROFILE DAN PEMESANAN LAYANAN JASA BERBASIS WEB PT GEOTERRA https://ejournal.upbatam.ac.id/index.php/jif/article/view/8028 <p>The company profile information system is a method used by companies to introduce themselves to the general public and convey information about the type of business they are engaged in.
