Abstract

Dengan tren yang mengkhawatirkan dalam beberapa tahun terakhir, penyakit jantung masih menjadi penyebab kematian paling umum di Indonesia dan di seluruh dunia. Tujuan dari penelitian ini adalah untuk meningkatkan pemahaman dan prediksi penyakit jantung koroner dengan menggunakan metode pohon keputusan dengan algoritma C4.5. Algoritma ini unggul karena mudah digunakan dan dapat digambarkan sebagai pohon keputusan berdasarkan faktor risiko pasien. Usia, jenis kelamin, nyeri dada, tekanan darah sistolik, kadar kolesterol total, denyut jantung maksimal, dan potensi adalah beberapa faktor risiko penting dalam studi ini. Algoritma C4.5 bertujuan untuk membuat model prediktif yang membantu dalam diagnosis dan intervensi dini penyakit jantung koroner dengan memanfaatkan elemen-elemen ini. Hasil model pohon keputusan dapat dikomunikasikan dengan mudah kepada profesional karena sederhana dan dapat dipahami.

Abstract

In the digital era, the field of computer technology, especially Microsoft Office applications, is a basic skill that students must master to meet the demands of the business world. Microsoft Office, including Word, Excel, and PowerPoint, not only increases productivity but also helps students adapt to a professional work environment. This Community Service (PKM) aims to determine the use of Microsoft Office applications to support the work practice activities of students at Taruna Bhakti Junior High School (SMP) Bogor Regency. The PKM method used is Presentation, discussion, and direct practice carried out at the SMP School. The results of the skills show that students are able to understand the basic concepts of using Microsoft Word for information, Excel for data processing, and Power Point for visual presentations. However, limited training time is a major obstacle in achieving optimal results. This study highlights the importance of mastering Microsoft Office as part of a comprehensive professional learning plan to improve students' abilities both in academics and in the workplace in the future. The results of this PKM are expected to be a guideline for Taruna Bhakti Junior High School, especially students, to be more active in learning computers, especially Microsoft Office.
