Pelaksanaan pengabdian kepada masyarakat ini dilaksanakan dengan tujuan untuk meningkatkan pengetahuan, wawasan serta kompetensi bagi para santri, terutama Bahasa Inggris. Kegiatan ini berfokus pada pelatihan tata Bahasa Inggris dengan jenis materi yang disesuaikan dengan karakter dan kebutuhan para santri. Teknik pembelajaran tata bahasa yang digunakan pada pelatihan tata Bahasa Inggris ini adalah dengan menggunakan teknik Dictogloss (dikte). Dictogloss adalah aktivitas dikte kelas di mana peserta didik diharuskan merekonstruksi teks pendek dengan mendengarkan dan mencatat kata-kata kunci, yang kemudian digunakan sebagai basis untuk membuat sebuah kalimat lengkap. Pelatihan ini diikuti oleh 30 santri dengan kisaran usia 10 sampai dengan 13 tahun. Dikarenakan masih dalam keadaan pandemic Covid-19 maka pelatihan ini dilaksanakan secara daring yaitu dengan memanfaatkan aplikasi Zoom. Hasil yang diharapkan adalah para santri dapat membuat kalimat dalam Bahasa Inggris dengan tata Bahasa yang baik dan benar

Mifasol Learning House is a non-profit organization that works for the community with the goal of providing additional education for underprivileged children in Depok, West. The children are given a variety of training materials to help them improve their insight and knowledge so that they can compete. English language training is one of the learning materials available at this study center. This is due to the students' lack of fundamental English knowledge. Correct and accurate English vocabulary is one of the fundamentals and the main issue that students face. Based on this, lecturers in the English Language and Literature study program at Bina Sarana Informatika University participate in community service activities. This activity is packaged as training aimed at increasing English vocabulary acquisition using the Vocabulary Self-Collection Strategy (VSS). Two cycles are used in the training method. Each cycle is divided into four stages: planning, implementation, observation, and reflection. The findings of this training demonstrate that VSS can be used to improve English vocabulary acquisition. The increase in the amount of understanding understood by students in cycles I and II demonstrates the improvement in student learning outcomes. In cycle I, the average test score was 58.2. In cycle II, the average test score was 70.2. The conclusion of this activity is that the VSS strategy can be used to improve students' English vocabulary acquisition.

This research aims to improve the accuracy of predicting student permit results in the digital era by utilizing machine learning techniques. The main focus is the use of a Decision Tree (DT) model optimized with a Genetic Algorithm (GA) to overcome the limitations of accuracy and testing of conventional methods. This research began with collecting student academic data, followed by preprocessing to eliminate incompleteness and organize the data format. The DT model is then built and optimized with GA, which is inspired by biological evolutionary processes to improve feature selection and parameter tuning. The results show a significant increase in prediction accuracy, from 86.19% to 87.68%, and an increase in the Area Under Curve (AUC) value from 0.755% to 0.788%. This research not only proves the effectiveness of GA integration in improving DT models, but also paves the way for the application of evolutionary techniques in educational data analysis and other fields. The main contributions of this research include the development of more accurate prediction models and practical applications in educational contexts, with the hope of assisting educational institutions in making more informed decisions for their students.

In the world of education, multimedia is used as an effective, attractive, efficient, and easy-to-use learning media in terms of learning assessment. Currently, the method of learning English at YPK Karya High School is still face-to-face and textbooks, the difficulty of students cannot listen to the speech and vocabulary sentences conveyed by the teacher and cannot write the vocabulary sentences correctly, therefore researchers make alternative English learning with multimedia, as an easy and interactive learning solution. The model used is ADDIE, and there are 5 stages: analysis, design, development, implementation, and evaluation. The subjects in this study were 1 principal, 2 teachers, 3 students. The methods used to collect data were interviews and observations. After obtaining the results of the analysis, the researcher designs the device requirements and multimedia design with the aim of providing a complete picture of the application. The design was performed using the Flash Professional CS5 application, an application specifically designed to create animation, and Photoshop 7.0 for image creation. Finally, the application for failures, system errors, and application maintenance. The results of the research on interactive learning English with multimedia are very helpful for students of SMA YPK Karya Tangerang because it is simpler and easier to repeat.

Chronic Kidney Disease, which is often abbreviated as PGK, is a serious disease that is of major concern to society and the medical world. This disease can cause various serious complications if not treated properly and early. Therefore, accurate prediction of CKD is very important to support early intervention that can slow disease progression, prevent further complications, and increase the patient's chances of recovery. This research aims to increase the accuracy of PGK predictions by developing a hybrid model that combines the K-Nearest Neighbors (KNN) algorithm with optimization using the Genetic Algorithm (GA). In this approach, the KNN algorithm is used to build a prediction model, while GA acts as an optimization tool that improves model performance. The effectiveness of the optimized model is evaluated using key metrics such as accuracy, precision, recall, and area under the curve (AUC). The results show a significant increase in performance, with accuracy increasing by 17.75%, precision increasing by 23.84%, and recall increasing by 5.34%. This research makes an important contribution to the development of data mining technology for clinical applications and opens up opportunities for further improvements in the future in increasing the prediction accuracy of chronic diseases such as CKD

Mathematics is a basic science that humans always use to help solve all life problems, because to solve problems that require computation such as calculating finances, calculating time differences, most people think that learning mathematics seems difficult, complicated, and boring so mathematics lessons are included in the category of lessons that are less popular with many students. This study aims to analyze the effect of the Scratch application on interest in learning mathematics using the Unified Theory of Acceptance and Use of Technology (UTAUT) at SMPIT Islamic City. This study examines performance expectations (Performance Expectancy), effort expectations (Effort Expectancy), and facilitating conditions (Facilitating Conditions) on Scratch on students' Interest in Learning Mathematics. The research sample consisted of 51 7th-grade students of SMPIT Islamic City. Data were collected through questionnaires and analyzed using multiple linear regression. The results showed that performance expectations (Performance Expectancy) had a positive and significant effect on Interest in Learning Mathematics (t count = 3.827, p <0.05). Furthermore, effort expectancy does not have a positive and significant influence on Mathematics Learning Interest (t count = 1.140, p > 0.05). Finally, the condition of the facilities has a positive and considerable influence on Mathematics Learning Interest (t count = 2.841, p < 0.05). Simultaneously, the three independent variables significantly influence Mathematics Learning Interest, with an F count value of 26.386 and an R square of 0.627.
