Abstract

Aksara sunda sebagai aksara nusantara diperkirakan sudah ada sejak abad ke 5, dalam bidang komputer aksara sunda sudah resmi menjadi bagian standar unicode pada tahun 2008 sehingga karakter dari aksara sunda dapat digunakan sebagai font, ataupun pada proses komputerasasi lainya. Bahasa sunda sendiri merupakan bahasa yang sehari-hari digunakan khusunya oleh masyarakat jawa barat, serta merupakan aset penting bagian dari kebudayaan sunda. Namun seiring berjalanya zaman, budaya sunda perlahan terkikis. Dari itu diperlukan tindakan guna melestarikan budaya sunda salah satunya dengan mempelajari aksara sunda. Aksara sunda mempunya pola tulisan yang rumit, dengan itu pola aksara sunda dapat dipelajari oleh komputer untuk membantu masyarakat belajar bahasa sunda. Tahap pengenalan aksara sunda terdiri dari dua proses yaitu tahap ekstraksi ciri dan klasifikasi. Metode modified direction feature (MDF) adalah salah satu metode ekstraksi ciri, dimana metode ini akan mengekstraksi ciri citra aksara sunda menjadi sebuah vektor berdasarkan arah transisi dari piksel aksara sunda tersebut. Selanjutnya metode paling mudah di implementasikan untuk klasifikasi adalah K-Nearest Neighbor (K-NN). K-NN bekerja dengan cara membandingkan jarak/kemiripan antara data yang di uji dengan data latih. Hasil dari penelitian ini menjelaskan bahwa MDF dan K-NN mampu dengan baik mengenali aksara sunda, dimana akurasi tertinggi yang berhasil didapatka sebesar 87.5% dengan nilai K=5

Abstract

At one of the goods distribution organizations in Bandung, manual recording problems such as data mistakes, delayed information, and challenges with inventory analysis must be addressed, and here is where the inventory information system comes in. An inventory system must be implemented to improve accuracy and efficiency in inventory management. With the correct technology, the business can reduce data errors, speed up information access, do practical inventory analysis, and increase productivity when taking and maintaining inventory. This study develops a web-based inventory information system using the MySQL database from the XAMPP application, the Laravel framework, and the PHP programming language. Representative data modeling and the creation of user-friendly interfaces are critical components of the design focus, which also considers proper technology selection. In order to better understand user needs and provide answers, system design will use the Object-Oriented Software Engineering (OOSE) model. In order to help with more precise decision-making in inventory management, the Last-In-First-Out (LIFO) method is used in inventory data analysis. Inventory may be easily monitored by using LIFO to offer information on nearly depleted stock and out-of-stock items. One of the Bandung-based goods delivery companies has seen notable gains due to the adoption of the new inventory system. With this new technology, the business may get past problems with manual recording, like data inaccuracies, delayed information, and challenges with inventory analysis. By streamlining the recording process and facilitating more efficient inventory management, this system facilitates better access to inventory information and increases the efficiency of inventory management. In summary, using an inventory system is an excellent way to get around problems with manual goods recording. This solution increases inventory management efficiency and speeds up the recording process for one of the Bandung-based commodities delivery enterprises. Its deployment offers significant advantages, improving the company's overall operating performance and facilitating more effective inventory management.

Abstract

Teachers play a central role in determining the success of the educational process, especially in mathematics learning, which requires a deep understanding of the subject matter. A professional mathematics teacher is expected to possess adequate Mathematical Content Knowledge (MCK) to deliver the material effectively. Therefore, prospective teachers need to be equipped not only with pedagogical skills but also with strong content mastery. This level of knowledge can be analyzed through the dimensions of the Revised Bloom’s Taxonomy, which includes factual, conceptual, procedural, and metacognitive knowledge. This study aims to identify the Mathematical Content Knowledge abilities of prospective mathematics teachers based on the Revised Bloom’s Taxonomy. The research used a quantitative method. The population consisted of seventh-semester students in the Mathematics Education (Tadris Matematika) Program at the Faculty of Tarbiyah and Teacher Training, IAIN Syekh Nurjati Cirebon. A total of 44 students were selected using cluster random sampling. Data collection techniques included non-test (questionnaire/self-report) and test (written questions). Data analysis involved data presentation, normality testing, and difference testing.The results showed that the Mathematical Content Knowledge of prospective mathematics teachers based on the knowledge dimensions of the Revised Bloom’s Taxonomy was consistent between test results and questionnaires. The highest level of MCK was found in the procedural knowledge dimension with a percentage of 27.12% based on the test results. There were no significant differences between male and female participants. Keywords: Mathematical Content Knowledge, Prospective Teachers, Revised Bloom’s Taxonomy
