Abstract

One of the problems related to population that still has to be faced by Simalungun is the problem of the imbalance in the distribution of the population. Incomplete division of the population brings problems to population density and population pressure in an area. This study uses data sources from the Central Statistics Agency (BPS) Simalungun. The data used in this study is data from 2015-2019 which consists of 32 Districts. Therefore, the researchers used the K-Means algorithm in clustering 32 sub-districts in Simalungun Regency. The data will be processed by clustering in 3 clusters, namely clusters with high population levels, clusters with moderate population levels and clusters with low population levels. The iteration process takes 5 times so that the results obtained are 4 sub-districts with high population level clusters (C1), 11 cluster sub-districts with moderate population level (C2) and 17 cluster sub-districts with low population level (C3)

Abstract

Algoritma adalah kunci utama dalam pemrograman komputer yang berisi urutan dari langkah-langkah logis penyelesaian masalah yang disusun secara sistematis. Kata logis merupakan kata kunci dari sebuah algoritma yang harus dibuat secara runut agar komputer mengerti dan mampu mengeksekusinya. Analisis kasus sangat dibutuhkan dalam membuat sebuah algoritma, misalnya proses apa saja yang sekiranya dibutuhkan untuk menyiapkan sebuah persoalan yang harus diselesaikan. Tahap pemecahan masalah adalah proses dari masalah hingga terbentuk suatu algoritma. Tahap implementasi adalah proses penerapan algoritma hingga menghasilkan solusi. Solusi yang dimaksud adalah suatu program yang merupakan implementasi dari algoritma yang disusun. Dalam dunia pemrograman komputer, algoritma berguna untuk merancang berbagai jenis program mulai dari program sederhana hingga program yang sangat kompleks. Algoritma berperan sebagai logika untuk menentukan program yang akan dibuat. Algoritma juga sangat penting diterapkan pada komputer dan kehidupan sehari-hari karena dengan algoritma komputer dapat digunakan untuk memproses data, melakukan perhitungan, membuat inferensi otomatis dan memecahkan masalah di komputer. Dalam matematika algoritma adalah sebuah prosedur atau langkah-langkah untuk proses penghitungan yang digunakan untuk memecahkan sebuah masalah dalam matematika, pemrosesan data dan penalaran otomatis sehingga bisa dilakukan dengan baik dan benar secara berurutan. Algoritma dalam matematika dan komputer saling berkaitan, mempengaruhi dan berhubungan karena memiliki tujuan yang sama

Abstract

Technology in this era is growing rapidly, especially in the field of computers and technology. Where we can see that these developments can facilitate the work of humans or employees and employees. In the education sector, computer science is needed so that teachers can easily provide up-to-date material and are not left behind in today's very rapid technological developments. For this reason, training on programming-based computer science is needed. Many teachers or employees in their understanding of knowing computers are only limited to Ms. Because of that, Office is often used in daily activities. In computer science, there are actually many applications/programs that can make work easier. For this reason, this training was created to introduce one of the application programs in computer science, namely the Visual Studio Net application and the PHPMyAdmin Database. In the training activities carried out at the UISU Siantar Project Islamic Private Vocational School to build a desktop-based information system development process or an application embedded in a computer. Application designed with offline software that has been prepared by the school

Abstract

The rapid development of digital technology, especially in the field of education, requires all students to be more creative. Students can utilize technology-based learning media, one of which is the Canva application. Canva is an online-based application that provides attractive designs in the form of templates, features, and categories provided in it. This community service aims to increase students' creativity. The form of community service activities is in the form of socialization with material presentation using lecture methods, QA and direct practice. The students who participated in this training were very enthusiastic and were able to apply the material and practice directly. This activity also involved the participation of lecturers and students of STKOM Tunas Bangsa, as well as the principal and teachers. It is hoped that this community service activity can have a positive impact on students and encourage the development of students' creativity in a sustainable manner.ABSTRAKPerkembangan teknologi digital yang sangat pesat, khususnya dibidang pendidikan menuntut semua siswa-siswi harus lebih kreatif.  Siswa-siswi dapat memanfaatkan media pembelajaran berbasis teknologi salah satunya adalah aplikasi Canva.

Abstract

This study examines strategic approaches to strengthening human resource management in addressing the challenges faced by agricultural entrepreneurs to support sustainable food security. The research focuses on identifying competency gaps, organizational learning patterns, performance systems, motivation mechanisms, and digital adoption within agricultural enterprises. A mixed method approach was employed, combining structured questionnaires and semi-structured interviews with agricultural entrepreneurs, extension agents, and institutional stakeholders. Quantitative data were analyzed using descriptive and inferential techniques, while qualitative data were examined through thematic analysis to identify recurring patterns and contextual insights. The findings reveal that core competencies, particularly managerial and digital skills, remain limited and unevenly distributed. Organizational learning processes are largely informal, leading to inconsistent knowledge transfer and weak innovation capacity. Performance management is underdeveloped, with minimal use of structured indicators or incentive based motivation systems. Digital adoption is hindered by limited infrastructure, low literacy, and financial constraints, resulting in slow technological transformation. The study concludes that strengthening human resource management through structured training, integrated learning systems, performance frameworks, and digital capacity building is essential for enhancing entrepreneurial resilience and supporting sustainable food systems. These findings provide a strategic foundation for policymakers, training institutions, and agricultural organizations to design targeted interventions that strengthen agricultural entrepreneurship and contribute to long term food security.
