The development of artificial intelligence can be used as a benchmark for technological developments. Many problems can be solved using this artificial intelligence concept. One of them is a water jug ​​logic game. The water jugs problem is a game requiring converting a situation into another desired situation using a certain set of operations. The objective of this game is for players to develop their deductive reasoning skills by figuring out how to move x litters of water from one teapot to another. To accomplish this, they will refer to the beginning value that has to be filled in each teapot and the end value that needs to be filled in each teapot. Using the A* algorithm and the Breadth-First Search (BFS) algorithm, which both fall under the umbrella of artificial intelligence, it is possible to find a solution to this issue. The A* algorithm is a Best First Search algorithm that combines Uniform Cost Search and Greedy Best-First Search, while the Breadth-First Search algorithm is a graph search algorithm that performs a wide search at each level. This study analyzed the effectiveness of the A* and BFS algorithms in solving the water jug ​​logic problem, both from the number of steps and the time required for completion. The results of the tests were carried out, and it is known that the BFS algorithm is more effective than the A* algorithm because the BFS algorithm can provide a number of alternative solutions to the water jug ​​logic problem with various conditions.</p> Bonifacius Indriyono Widyatmoko Copyright (c) 2022 Bonifacius Indriyono, Widyatmoko http://creativecommons.org/licenses/by-sa/4.0 2022-07-27 2022-07-27 7 2 88 95 10.25139/inform.v7i2.4484 Analysis and Design of User Interface and User Experience of Regional Tax Enterprise Resources Planning System with Design Thinking Method https://ejournal.unitomo.ac.id/index.php/inform/article/view/4729 <p>Regional Tax is one of the main sectors of independent income owned by each City or Regency to fund infrastructure development, education development, health services, and much more. The government agency that manages this regional tax is <em>Badan Pendapatan Daerah</em>, abbreviated as <em>Bapenda</em>. In particular, the West <em>Bandung Bapenda</em> has not implemented an online-based Regional Tax service system. This management system cannot be developed, and taxpayers have no independent account management. The appearance and user experience of the existing system has not matched the current design trends and the latest organizational structure. This greatly obstructs the services of <em>Bapenda</em> to taxpayers due to the lack of digital transparency. The system's flow is quite convoluted, thus affecting the quality and slow access to information. These limitations will be resolved through structured research using the Design Thinking and Usability Testing method for testing so that later it can be translated into an Enterprise Resources Planning system design with a good User Interface / User Experience. This method is structured following five phases: empathy, define, ideate, prototype, and test. The empathy phase aims to understand user problems, the define phase identifies and maps problems, the ideate phase aims to generate ideas, the prototype phase aims to implement the design based on the results of the previous steps, and the test phase aims to test the user. The final phase is the test phase and aims to test the user. The results obtained after applying this method follow user expectations.</p> Vicky Ardian Subarjah Ari Purno Wahyu Copyright (c) 2022 Vicky Ardian Subarjah http://creativecommons.org/licenses/by-sa/4.0 2022-07-29 2022-07-29 7 2 96 106 10.25139/inform.v7i2.4729 Digital Library Analysis and Design Using Iconix Process Method (Case Study: SMA Negeri 1 Ngimbang) https://ejournal.unitomo.ac.id/index.php/inform/article/view/4764 <p>The application of information technology in various companies will improve employees’ performance so that the business results obtained by the company are of higher quality. The school library has a relatively significant influence on the learning process and expands students’ knowledge. However, in reality, many libraries still have not utilized information technology to manage their management, so some parties sometimes encounter obstacles that can hinder performance and efficiency. This study built a web-based library information system using the Iconix process method with the case study <em>SMA Negeri 1 Ngimbang, Indonesia</em>. The findings of this study will be able to be implemented, promoting the efficiency of data and library information management and boosting.</p> <p>&nbsp;</p> Anindo Saka Fitri Eka Nanda Sulastri M.

This tool has a very important role because it provides accessible information to the operator about the safe working load (SWL) that the crane can lift. Mobile cranes have a high accident potential when compared to tower cranes, and this is because mobile cranes have high mobility. In this paper, a prototype LMI has been made on a mobile crane based on a microcontroller that can provide value. The method used is an algorithm to find the closest value from the lifting load chart of a crane car. The programming algorithm is still manual, namely by equating and comparing boom crane conditions such as boom length, boom angle, and radius contained in the lifting load chart with the results of measuring boom crane conditions by sensors. The nearest value search algorithm follows the rules of how to read the mobile crane lifting load chart. The test results show that the sensors used to measure boom length, boom angle, and actual load each have a maximum relative error of 0.92%, 8%, and 4%, respectively. Meanwhile, to find the SWL value, the comparison scanning method can provide the SWL value according to the lifting load chart of the mobile crane. It can provide accurate information on whether the lifting load process is safe or overloaded.</p> Akhmad Fahruzi Marselinus Amalia Lamanele Trisna wati Copyright (c) 2022 Akhmad Fahruzi, Marselinus Amalia Lamanele, Trisna wati http://creativecommons.org/licenses/by-sa/4.0 2022-07-30 2022-07-30 7 2 113 119 10.25139/inform.v7i2.4746 E-Greengrocers: A Mobile Information System for Supporting Business in The Traditional Market https://ejournal.unitomo.ac.id/index.php/inform/article/view/4674 <p>The covid-19 pandemic has affected many sides of human life. World Health Organization (WHO) and health sectors worldwide have suggested physical distancing to battle the pandemic. The physical distancing is causing many adjustments in the business implementations. For rural developing countries, grocery shopping at itinerant greengrocers may increase the risks of infection because there are direct interactions between the seller and the buyer and the habit of shopping in a crowd without concerning the physical distancing protocol. E-Greengrocers application is proposed as the innovative approach to help the traditional market support their activities with fewer contact interactions. The application is projected to facilitate a safe transaction between greengrocers and their buyers. This research was developed using the waterfall methodology and descriptive case study. Observations and the distribution of questionnaires among the itinerant greengrocers and buyers are used as a tool to obtain the necessary data. The questionnaire result shows that all users were satisfied with the features provided. More than 61% of users perceived it helpful, and 30% found it very helpful.&nbsp; The features facilitated minimum contact on transactions and maintained sustainable income from the itinerant's greengrocers’ point of view.</p> Dhiani Tresna Absari Liliana Bambang Prijambodo Copyright (c) 2022 Dhiani Tresna Absari, Liliana http://creativecommons.org/licenses/by-sa/4.0 2022-07-30 2022-07-30 7 2 120 124 10.25139/inform.v7i2.4674 Development of Historical Learning Media Based on Virtual Reality of The National Awakening Museum https://ejournal.unitomo.ac.id/index.php/inform/article/view/4709 <p class="IEEEAbtract"><span lang="EN-GB" style="font-weight: normal;">In history learning, visits to locations such as museums or other historical places in the pandemic Covid-19 situation are minimal. However, learning activities must be continued, and the existing conventional learning media in the pandemic scenario are deemed less to provide the experience. Based on previous learning experiences, an obligation to transfer knowledge from museum managers, and technological developments related to virtual reality, supports an idea to develop a museum national awakening virtual reality. This VR application is expected to become an alternative historical learning medium. This study aims to create a museum national awakening VR based on 360-degree images of the museum location. The multimedia development life cycle (MDLC) is chosen as the method used in developing the proposed VR application. The procedure consists of six steps: defining the concept based on on-site observation and interviews with the manager, creating the design, collecting the material, assembling materials and interactions with code, testing the proposed application, and distributing the system. The proposed virtual tour application has been successfully developed following the methodological principles chosen. It is also supported by a series of observations in the field using a cognitive walkthrough approach. The application was then reviewed by five experts: historians, multimedia, and learning experts. The location detailing is perfectly captured, including all the objects shown in each museum room. The quiz feature also strengthens the VR application as the learning medium, but it needs to be developed further in the evaluation section.</span></p> Mira Suryani Rispansah Sakti Rusidiawan Rudi Rosadi Copyright (c) 2022 Mira Suryani, Rispansah Sakti Rusidiawan, Rudi Rosadi http://creativecommons.org/licenses/by-sa/4.0 2022-07-30 2022-07-30 7 2 125 131 10.25139/inform.v7i2.4709 Analysis and Design of Employee Attendance Application System Using RFID E-KTP Technology with ICONIX Process Method https://ejournal.unitomo.ac.id/index.php/inform/article/view/4738 <p>Attendance is an essential reference for the quality of human resources, including those who will carry out an activity, such as employees and supervisors. In carrying out these attendance activities, some still use it manually, such as recording in a detailed book, and its storage is still classified as conventional. Therefore, an employee attendance system that can record and manage data easily can be done quickly, efficiently, and accurately. This paper aims to analyze and design an employee RFID attendance information system using the ICONIX Process method. This RFID system is made using an RFID E-KTP supported by a database, where the RFID E-KTP is very easy to use. The results of this study are the analysis and design of an information system for implementing an employee attendance system based on RFID technology. The scope of information includes records of arrival times and return times. The results of the analysis and research design can be implemented properly in accordance with the proposed business process and can be a recommendation for various business actors to record employee attendance activities using RFID on the E-KTP.</p> Mohammad Farizd Brillyan Putra Pradana Dwi Shahita Seftin Fitri Ana Wati Copyright (c) 2022 Mohammad Farizd, Brillyan Putra Pradana, Dwi Shahita, Seftin Fitri Ana Wati http://creativecommons.org/licenses/by-sa/4.0 2022-07-31 2022-07-31 7 2 132 142 10.25139/inform.v7i2.4738 Design Of Interactive Smart Mirror System for Digital Information Display Based on Multitasking Approach Using Raspberry Pi https://ejournal.unitomo.ac.id/index.php/inform/article/view/4757 <p>The average time humans look in the mirror is in the early morning when they will get ready for work. A person can rarely focus on other activities such as watching television for the latest news, checking the clock for the correct time, or even checking the weather forecast. Therefore, the purpose of this research is to design an interactive smart mirror that functions as a personal digital assistant to provide a schedule of daily activities, including recognizing the owner's face for access to the smart mirror, displaying weather forecasts, displaying the date and time, as well as the latest news. Unlike most smart mirrors in previous studies, this smart mirror design is connected to a facial recognition system. This will work for such security systems that the user will be granted access to the system only when the system detects that it is the owner. The method used in the research is the agile methodology for the project's flexibility and structured work organization. Experiments will be carried out on all test data starting from the accuracy of turning the smart mirror on and off, loading the weather on average 5 seconds after internet connection, making sure the Pi-camera component is active, and checking for face profiles. The system will test the data on each unit individually and as a whole to ensure efficiency and reliability. The experimental results in this study provide an accurate value of 100%.</p> Sandra Nwokoye Azubuike Aniedu Chukwunenye Okafor Austine Nzemalu Copyright (c) 2022 SANDRA NWOKOYE, Azubuike Aniedu, Chukwunenye Okafor, Austine Nzemalu http://creativecommons.org/licenses/by-sa/4.0 2022-07-31 2022-07-31 7 2 143 147 10.25139/inform.v7i2.4757 Quadcopter Main Board Design with PID Algorithm as Controller https://ejournal.unitomo.ac.id/index.php/inform/article/view/4687 <p><em>Kontes Robot Terbang Indonesia (KRTI)</em> Flight controller division has a mission to independently make an unmanned aerial vehicle (UAV) controller. UAV controllers are usually made by non-local manufacturers, who have a package between the controller and the aircraft. Due to limited pins and specific functions, most controllers cannot adapt to user requirements. For this reason, in this study, we made a UAV controller with a more significant number of pins that can be programmed independently. Main Controller is a master board device used to control the stability of the UAV when flying. The main controller has been designed specifically for certain products so that the UAV cannot be modified. In this study, it is proposed to make the main controller that is specifically designed to fly a Quadcopter UAV. Movement control for quadcopter stability when flying using the Proportional Integral Derivative (PID) method. The main controller has a function that is to regulate the entire course of flight on unmanned vehicles. PID control can adapt to changes so that the system becomes stable. The PID control on the Main Controller is intended to balance the quadcopter concerning its orientation angle. The Main Controller is also tasked with recording data from sensors such as the Inertial Measurement Unit (IMU) and reading data from the remote. The controller successfully flew the quadcopter with a P value of 0.245, an I value of 0.0139, and a D value of 0.0085.</p> Mochamad Bachtiar Iwan Kurnianto Wibowo Nur Cahyo Ihsan Prastyawan Maretha Ruswiansari Hendy Briantoro Nofria Hanafi Niam Tamami Hendhi Hermawan Eko Budi Utomo Copyright (c) 2022 Mochamad Bachtiar http://creativecommons.org/licenses/by-sa/4.0 2022-07-31 2022-07-31 7 2 148 155 10.25139/inform.v7i2.4687 DSM-V Modelling as an Expert System Pilot in Classification of Insomnia Tendency Based on Time Range https://ejournal.unitomo.ac.id/index.php/inform/article/view/4472 <p class="IEEEAbtract"><a name="_Hlk89736348"></a><span lang="EN-GB" style="font-weight: normal;">Insomnia is a form of sleep disorder. This study develops an expert system model that can help determine the tendency of insomnia based on the Diagnostic and Statistical Manual for Mental Disorders (DSM-V) guidelines. The forward chaining design method was used in this study because it is bottom-up by collecting facts from patients and concluded based on the DSM-V guidelines. The forward chaining method was chosen to test the hypothesis of the classification of insomnia tendencies. The factual information then acts as a knowledge base fed into computer programs that can generate system rules. In addition, tacit knowledge is used, as evidenced by O'Leary validation, to strengthen the validation of psychologist practitioners. There are three validation criteria: the accuracy of the knowledge base, completeness of the knowledge base, and condition-decision matches. </span><span lang="EN-GB" style="font-weight: normal;">The parameters used are based on complaints, dysfunction, time range, and other factors. The results of modeling and analysis of the rule system using the forward chaining method classify insomnia tendencies into three types based on time range: episodic, persistent, and recurring. The validation results carried out by practicing psychologists based on the analysis showed that the three rule systems were following the DSM-V guidelines and practical experience.</span></p> Talitha Syahla Janiar Arifin Wahyuningdiah Trisari Harsanti Putri Tia Rahmania Copyright (c) 2022 Talitha Syahla Janiar Arifin, Wahyuningdiah Trisari Harsanti Putri, Tia Rahmania http://creativecommons.org/licenses/by-sa/4.0 2022-07-31 2022-07-31 7 2 156 161 10.25139/inform.v7i2.4472 Clickbait Detection of Indonesian News Headlines using Fine-Tune Bidirectional Encoder Representations from Transformers (BERT) https://ejournal.unitomo.ac.id/index.php/inform/article/view/4686 <p class="IEEEAbtract"><span lang="EN-GB" style="font-weight: normal;">The problem of the existence of news article that does not match with content, called clickbait, has seriously interfered readers from getting the information they expect. The number of clickbait news continues significantly increased in recent years. According to this problem, a clickbait detector is required to automatically identify news article headlines that include clickbait and non-clickbait. Additionally, many currently existing solutions use handcrafted features and traditional machine learning methods, which limit the generalization. Therefore, this study fine-tunes the Bidirectional Encoder Representations from Transformers (BERT) and uses the Indonesian news headlines dataset CLICK-ID to predict clickbait (BERT). In this research, we use IndoBERT as the pre-trained model, a state-of-the-art BERT-based language model for Indonesian. Then, the usefulness of BERT-based classifiers is then assessed by comparing the performance of IndoBERT classifiers with different pre-trained models with that of two word-vectors-based approaches (i.e., bag-of-words and TF-IDF) and five machine learning classifiers (i.e., NB, KNN, SVM, DT, and RF). The evaluation results indicate that all fine-tuned IndoBERT classifiers outperform all word-vectors-based machine learning classifiers in classifying clickbait and non-clickbait Indonesian news headlines. The IndoBERT<sub>BASE</sub> using the two training phases model gets the highest accuracy of 0.8247, which is 0.064 (6%), outperforming the SVM classifier's accuracy with the bag-of-words model 0.7607.</span></p> Diyah Utami Kusumaning Putri Dinar Nugroho Pratomo Copyright (c) 2022 Diyah Utami Kusumaning Putri, Dinar Nugroho Pratomo http://creativecommons.org/licenses/by-sa/4.0 2022-07-30 2022-07-30 7 2 162 168 10.25139/inform.v7i2.4686
