Abstract

Perkembangan teknologi telah menyentuh di berbagai sektor, salah satunya adalah di bidang pendidikan bagi para siswa. Para siswa dituntut untuk bisa paham dan mengikuti perkembangan jaman dengan memanfaatkan teknologi informasi. Namun, pemanfaatan teknologi belum sepenuhnya diterapkan untuk peningkatan kualitas para siswa. Para siswa-siswi sekolah menengah pertama (SMP) dituntut untuk memiliki keterampilan lebih untuk menghadapi tantangan perkembangan teknologi pada umumnya. Karena pada kurikulum SMP sudah diselenggarakan kurikulum merdeka belajar yang artinya menerapkan program pembelajaran tatap muka dan pembelajaran sistem projek. SMP Negeri 02 Margoyoso adalah salah satu sekolah menengah pertama yang menerapkan program kurikulum merdeka belajar. Pada sekolah tersebut belum ada mata pelajaran yang secara khusus melakukan pembahasan lebih mengenai penggunaan aplikasi Microsoft Office di Windows seperti Excel, Word dan Power Point. Meskipun aplikasi ini sangat berguna bagi siswa apalagi dengan kejuruan perkantoran. Aplikasi tersebut berguna baik dalam mengerjakan tugas sekolah ataupun kegiatan dilingkungan sekitar mereka. Untuk itu diadakanlah pelatihan Microsoft Office ini agar bisa meningkatkan pembelajaran siswa baik dalam mengerjakan tugas sehari-hari disekolah dan sebagai bekal dasar mereka setelah keluar sekolah nanti, agar bisa diterapkan di sekolah menengah atas ataupun saat mereka kuliah dan lingkungan kerja. Pada pelatihan kali ini membahas mengenai Microsoft Office Excel. Microsoft Office Excel ini umumnya mencakup berbagai topik, termasuk dasar-dasar spreadsheet, manipulasi data, rumus, fungsi, analisis data dan visualisasi. Pelatihan ini melibatkan latihan langsung untuk meningkatkan keterampilan menggunakan fitur  seperti rumus, fungsi, grafik, dan validasi data. Tujuan dari program kemitraan masyarakat ini adalah untuk meningkatkan keterampilan komputer siswa khususnya Microsoft Office Excel. Setidaknya semudah Microsoft Office Excel dengan alat khusus yang mereka gunakan untuk membuat laporan keuangan seperti misalnya menggunakan margin, memasukkan teks ke dalam tabel, membuat format tanggal dan waktu, dan menggunakan formula penjumlahan, pengurangan, pembagian dan perkalian serta penyusunan bentuk logika matematika yang tepat dan benar yang dapat diterapkan untuk menyelesaikan tugas dan kewajiban di SMP Negeri 02 Margoyoso.

Abstract

SMK YP Mulia Jakarta is a vocational high school that has adopted technology in its educational process, including the implementation of daily assessments, which were previously managed through Google Forms. Despite its use, this platform has several shortcomings, such as rigid scheduling options, the absence of automatic question randomization, limited participant authentication capabilities, and a lack of automated result analysis. Moreover, since Google Forms is a third-party tool, the school lacks full authority over the system and its data. To overcome these challenges, the author developed a custom web-based online testing system specifically designed to meet the requirements of SMK YP Mulia Jakarta. The system offers features such as configurable test timing, randomized questions, token-based access management, secure user authentication, and real-time, integrated result reporting.

Abstract

Advances in science and technology (IPTEK), especially information technology, make it easier to support community activities, but at the same time make various devices vulnerable to exploitation by cybercriminals [1]. One such activity is stealing data from Internet users through fake sites (also known as phishing sites) designed to look like the real thing. Phishing websites pose a serious threat to online information security and require an effective approach to detect and prevent them. To combat the proliferation of phishing websites in cyberspace, a classification is needed to predict which websites will be classified as phishing websites using the Decision Tree Classification Algorithm (CART) [2]. To improve the performance of the Decision Tree Classification (CART) algorithm and achieve better optimal accuracy, optimization using the bagging method is needed. A bagging technique that combines the results of several decision tree models is applied to improve the performance and reliability of the CART algorithm in detecting phishing websites [3]. In this research, we collected a dataset containing various characteristics related to the characteristics of phishing websites. The data is then processed and divided into subsets for model training and testing. The aim of this research is to optimize the decision tree classification algorithm (CART) by applying bagging techniques in the context of phishing website detection. Based on test results, applying the Decision Tree Classification Algorithm (CART) to classify phishing websites produces an accuracy of 96.61%, and when combined with bagging techniques, the accuracy increases by 1.13% to 97.74%. This experiment shows that optimization can improve the prediction accuracy of phishing websites by combining the Decision Tree Algorithm (CART) with bagging techniques. Keywords: Phishing Websites, Classification, Prediction, Algorithms, Decision Trees.

Abstract

Higher education in the digital era requires learning approaches that are able to adapt to individual student characteristics, including differences in learning styles. This study aims to develop a model for assessing students’ learning patterns and to provide more personalized learning recommendations using the Weighted Aggregated Sum Product Assessment (WASPAS) method. The data used are secondary data obtained from 1,000 students with seven learning criteria, namely academic score, course participation, attendance rate, physical activity, emotional engagement, device usage, and feedback score. The WASPAS method is applied through two main stages, namely the calculation of the Weighted Sum Model (WSM) and the Weighted Product Model (WPM), which are then aggregated to produce a composite WASPAS score for each student. Manual calculations are demonstrated using five student samples, while computations for the entire dataset are performed using Python in the Jupyter Notebook environment. The results show that students’ WASPAS scores range from 0.2815 to 0.9914 with a distribution that tends to be normal. Most students fall into the “fair” to “very good” learning pattern categories, while a small proportion are classified as “very high” and “requiring special attention.” Analysis based on visual, auditory, and kinesthetic learning styles indicates differences in average WASPAS scores across groups, supporting the effectiveness of the WASPAS method in integrating multiple learning criteria simultaneously. These findings demonstrate that WASPAS can be used as a decision support tool to map student learning profiles and assist in designing more adaptive, targeted, and personalized learning strategies in higher education

Abstract

This Community Service (PkM) activity was carried out at Rainbow Kids Kindergarten as an effort to improve teacher competency in implementing interactive learning based on digital technology. The problem faced by partners was the limited use of interactive digital learning media, so the learning process was not optimal in increasing student engagement and motivation. The purpose of this activity was to provide training on the use of the Quizizz application to teachers as a fun interactive learning innovation that is appropriate to the characteristics of early childhood. The implementation method included socialization, material delivery, demonstration of application use, hands-on practice in creating interactive quizzes, and activity evaluation. The implementation results showed an increase in teacher understanding and skills in designing and implementing game-based learning. In addition, teachers became more creative and innovative in compiling interesting and participatory learning materials. This activity is expected to contribute to improving the quality of learning and supporting digital transformation in early childhood education environments.
