Abstract

This study aims to describe the mathematical understanding ability of students regarding the concept of definite integral based on APOS Theory, and describe the achievement of each indikator of students' mathematical understanding ability regarding the concept of definite integral of algebraic functions based on APOS Theory. The research method used is descriptive qualitative. The data collection techniques used in this study were written tests and interviews. The results showed that the achievement in question number one on the K indikator 88.89%, L 83.33% and S 69.44%, most of the students who were able to solve the problem meant that they had been able to organise the actions, processes, and objects they had so that based on APOS theory, the student was at the level of understanding the scheme. Achievement in question number two on indikator K 80.55%, L 58.33% and S 50%. Most students are only able to identify properties and conditions, meaning that students only have the ability to understand at the action stage. Achievement in question number two on indikator K 86.11%, L 66.67% and S 63.88%. Most students are only able to identify properties and conditions and work on problems according to the steps.

Abstract

Abstrak−Penelitian ini bertujuan merancang dan mengimplementasikan sistem jaringan private menggunakan OpenVPN pada router MikroTik di Percetakan Gema Insani Press. Metode penelitian yang digunakan adalah deskriptif dan eksperimen dengan tahapan analisis kebutuhan, desain jaringan VPN, implementasi, pengujian, dan evaluasi. Penelitian ini juga membahas aspek keamanan, kestabilan koneksi, serta kemudahan manajemen jaringan. Hasil penelitian menunjukkan bahwa sistem VPN yang diterapkan berhasil menyediakan koneksi yang stabil, aman, dan mempermudah manajemen jaringan. Sistem ini meningkatkan efisiensi operasional dan keamanan komunikasi data antar workstation di lingkungan percetakan, serta dapat menjadi referensi implementasi jaringan private di usaha percetakan lainnya.

Abstract

The purpose of Community Service (PkM) is to provide counseling and training on the use of Gemini AI to improve teacher competence. One of the teacher competencies referred to in this PkM is pedagogical competence. This PkM was carried out at MI Arrahman. This activity was attended by the principal and teachers. This PkM activity was carried out for 3 days, including the introduction of artificial intelligence (AI), account creation, training in creating learning administration, learning tools, and learning evaluation. The implementation methods used include: 1) Observation stage, 2) Planning stage, 3) Preparation stage, 4) Implementation stage, 5) Discussion stage, and 6) Evaluation stage. The results of this PkM showed an increase from before the training in teacher understanding by 50% and after the training, teacher understanding increased by 100%.

Abstract

Applied graph is a compulsory course in the Pamulang Informatics Engineering study program. Applied graph is a course that teaches the concepts, algorithms, and practical applications of graph theory. Graph theory itself is a branch of discrete mathematics that studies network structures consisting of nodes (vertices) connected by edges (arcs). Although the applied graph course is an important course to study, some students still consider it difficult to understand.  The purpose of this study was to determine whether there was a difference in the mathematical disposition of students who were given treatment using the knowledge sharing strategy and students who were given treatment using the expository strategy. The research method used was a quantitative method with a quasi-experimental design. The sample used in this study consisted of 59 students. Data collection was carried out using a mathematical disposition questionnaire. The instrument was tested for validity on 136 students, with 29 valid statements, and for reliability using Cronbach's alpha coefficient 0.992. The analysis technique used an independent t-test with a p-value of 0.005. The results of this study indicate that there is a difference in the mathematical disposition of students who were given the knowledge sharing strategy and students who were given the expository strategy.
