The design method applied was the Technology Acceptance Model (TAM) which referred to the individual acceptance behavior of information technology systems. The analysis was carried out using the Structural Equation Modeling method with the Partial Least Square (SEM-PLS) model. The results achieved from this study prove that the interface convenience of the marketplace mobile application had a significant and positive effect on online buying interest in both male and female consumers. Based on the results of this study, it can be concluded that the convenience felt by consumers both male and female consumers when viewing the user interface of marketplace mobile applications will have an impact on online buying interest.</em></p> Layla Nurul Af’idati, Richard Richard, Indry A Pradipta, Endang Retnoningsih ##submission.copyrightStatement## https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5625 Tue, 27 Sep 2022 00:00:00 +0000 Tracking System on Solar Panels Using Microcontroller https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5602 <p><em>Solar energy is a renewable energy that has not been widely implemented in a mass manner. To optimize the use of a solar panel, usually a control system that can adjust the position of the solar panel automatically is employed to get the optimal power value. This prototype tracking system of solar panels is dynamically following the direction of sunlight. The supporting devices used in this prototype are LDR sensor, Servo, Arduino Uno, Ina219, Bread Boot Power Supply and solar cell which must be activated first to work. The servo will drive a 3D printing device that is connected to an LDR sensor that is sensitive to sunlight. The Ina219 component serves to absorb the intensity of the sun and convert it in terms of voltage (volts) and electric current (amperes). The energy absorbed by the solar panels in the form of voltage and electric current will be stored in the battery so that it can turn on the lights. The solar panel prototype will be placed in an open area to get optimal solar energy compared to static solar panels.</em></p> Bagaskara Sembada, Rafika Sari, Sugiyatno Sugiyatno ##submission.copyrightStatement## https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5602 Tue, 27 Sep 2022 00:00:00 +0000 Nutritional Status Classification of Toddlers Using K-Nearest Neighbor Algorithm https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5604 <p><em>Nutrition is important for the balance of the human body. Knowing the nutritional status is very important to realize the good and the quality human resources. Posyandu Parkit is one of the many Integrated Healthcare Center (posyandu) in Indonesia that provides health services for the community, one of which is monitoring and nutritional development of toddlers. However, the Posyandu Parkit in determining the nutritional status of toddlers is done manually; this method uses measurement parameters based on body weight (BB/U) which are less specific in showing the nutritional status of the toddler by matching manually with a reference standard table available in a healthy card (KMS). The purpose of this research is to produce a website that can determine the nutritional status of toddlers quickly and accurately. The system is designed using the K-Nearest Neighbor method which is a classification method. The K-Nearest Neighbor process is carried out by calculating the distance between the test data and the training data using the Euclidean distance formula, before sorting from the closest distance to the k-th order, then nutritional status is determined. The results of this study are a website that can determine the nutritional status of toddlers by applying the K-Nearest Neighbor algorithm with BB/U, TB/U, and BB/TB accuracies were 93.75%, 87.5%, and 93.75 %, respectively. </em></p> Nur Amanda Pratiwi, Prima Dina Atika, Herlawati Herlawati ##submission.copyrightStatement## https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5604 Tue, 27 Sep 2022 00:00:00 +0000 Online Booking Application for Long-Distance Train Ticket Adapted to the Covid-19 Protocol https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/4629 <p><em>Train is favorite transportation in Indonesia. The increase in the number of passengers from year to year is proof that rail transportation supports community mobility. Therefore, services are needed to accommodate the needs of the community in ordering train tickets. Currently, the train ticket booking system can be done offline or online. Especially for the online train ticket booking system, there are still some obstacles i.e., during the Covid-19 pandemic, a train ticket booking information system is also needed which must be adjusted to health protocols to minimize the spread of Covid-19 during travel by train, starting from the ticket booking process. The system development methodology used is Scrum, this methodology is a framework that applies the stages of planning, analysis, design and implementation to build or develop software where work is divided into time frames called sprints. The long-distance train ticket booking application has been able to minimize the accumulation of passengers in exchanging tickets at the train station platform.</em></p> Diah Asih Relawanti, Yopi Mahangga Ujung, Rossy Yanuar Pradania, Andi Nugroho, Achmad Kodar ##submission.copyrightStatement## https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/4629 Tue, 27 Sep 2022 00:00:00 +0000 Web-Based Mail Search Using the Levenshtein Distance Algorithm https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5606 <p><em>The use of information technology in filing letters has been widely applied, especially in government institutions. In the Administrative Affairs of the Police Information Technology Bureau, the archiving of incoming and outgoing letters is still done manually, by utilizing records in a large agenda book and stored in a large folder. The absence of a system capable of assisting mail processing causes work to be inefficient, especially in terms of searching for letters. The purpose of this research is to produce a website that can help search letters by applying the Levenshtein Distance Algorithm. The design begins with needs analysis, design, implementation, verification (system testing), operation and maintenance. A website that can search letters by applying the Levenshtein Distance Algorithm was generated. This website is very helpful in the process of searching for letters to the Administrative Affairs of the Police Information Technology Bureau.</em></p> Mayora Lolly Ishimora, Herlawati Herlawati, Sri Rejeki ##submission.copyrightStatement## https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5606 Tue, 27 Sep 2022 00:00:00 +0000 Export Management Information System: Evidence from Willbes Global Purwadadi Inc. https://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/5623 <p><em>The case study in this research is the export goods data report at Willbess Global Inc.
