<![CDATA[Informatics is intricately intertwined with the mastery of problem-solving. Within this discipline, one of the fundamental areas of study revolves around the concepts of branching and looping. During field studies, several student problems were identified, such as difficulty solving programming problems presented in the form of stories. This resulted in a lack of problem-solving skills among students when it comes to story problems. Additionally, there were issues with instructional media and less interactive teaching methods. The aim of this research is to design multimedia that implements a problem-based learning model to enhance students' problem-solving abilities. The research method used is Research and Development (R&D) with the ADDIE development model. The study involved 36 students from class X-B RPL at SMKN 1 Cimahi. The data obtained are as follows: 1) The development of interactive multimedia achieved an average score of 88. 2) There is an increase in students' problem-solving indicators, with an average pretest score of 40.13 rising to 68.38 in the posttest. Additionally, an N-Gain of 0.47 was obtained, with details as follows: understanding the problem at 0.60, devising a plan at 0.41, carrying out the plan at 0.35, and looking back at 0.34.

<![CDATA[Berita palsu dalam politik menjadi ancaman serius terhadap stabilitas demokrasi dan kepercayaan publik terhadap informasi. Fenomena ini tidak hanya meresahkan, tetapi juga memiliki dampak yang dapat mengganggu proses demokrasi serta kepercayaan masyarakat terhadap media dan pemerintah. Penelitian ini bertujuan untuk menyelidiki dan membandingkan kinerja dua algoritma yang berbeda, yaitu Naïve Bayes (NB) dan Convolutional Neural Network (CNN), yang telah dioptimalkan menggunakan Particle Swarm Optimization (PSO), dalam mendeteksi berita palsu di ranah politik Indonesia. Untuk mencapai tujuan ini, penelitian menggunakan dataset berita politik yang telah melalui proses text preprocessing, termasuk pembersihan data dan normalisasi teks. Hasil penelitian menunjukkan bahwa model Naïve Bayes secara konsisten mampu mengungguli kinerja CNN, baik dengan atau tanpa penerapan PSO. Akurasi model Naïve Bayes mencapai 90.71%, sementara CNN mencapai 80.86% tanpa PSO, 79.68% dengan PSO, dan Naïve Bayes dengan PSO mencapai 90.25%. Temuan ini menegaskan bahwa pendekatan menggunakan algoritma Naïve Bayes memiliki potensi lebih besar dalam mengidentifikasi berita palsu dalam konteks politik Indonesia. Kontribusi signifikan dari penelitian ini terletak pada pemahaman yang lebih mendalam mengenai metode deteksi berita palsu, serta memberikan wawasan yang penting bagi pengembangan strategi yang efektif dalam menanggulangi permasalahan berita palsu di era digital. Oleh karena itu, diharapkan bahwa penelitian ini akan memberikan nilai tambah dalam upaya mempertahankan keaslian informasi politik dan meningkatkan kualitas demokrasi di Indonesia.]]>

<![CDATA[Information system audits have an important role in an organization, namely they can help identify security risks that may be faced by the company's information system and ensure that the company complies with applicable information security standards and regulations. The problem faced is that there is no framework for knowing the extent to which the system is working properly. In conducting an information system audit, instruments are needed in the form of frameworks, principles or standards that have been determined by competent organizations in their field. COBIT 5 is a framework in the form of a collection of best practices related to IT governance that can be applied in information audit activities. Implementing an information system audit using COBIT 5 is carried out by collecting control documents and aligning them with COBIT 5 basic practices, then conducting an assessment on each selected domain based on existing control documents. In this study, the domains chosen were DSS and MEA with subdomains consisting of DSS1, DSS2, DSS3, DSS4, DSS5, DSS6, MEA1, MEA2. The research results show that the inventory transaction information system is at level 1 (performed process), meaning that the process in each selected domain has been implemented and is in accordance with its objectives. These results can be a reference for improving the governance of inventory transaction applications in particular and IT governance in general so that they are in line with the company's business objectives.]]>
