Scheduling in education has been a common issue faced, particularly concerning the mismatch between class hours and teacher availability. Addressing this necessitated careful precision and a significant amount of time for subject scheduling. Genetic algorithms emerged as a suitable choice for managing school subject scheduling due to their capability to address multi-criteria and multi-objective problems inspired by biological evolution. The concept of genetic algorithms could be effectively applied in the context of schedule arrangement within educational institutions. This study employed a quantitative methodology and implemented the Rapid Application Development (RAD) system development method. The utilization of genetic algorithms in subject scheduling, as demonstrated in this research, was deemed beneficial for correctional institutions previously engaged in manual scheduling processes. The outcomes indicated the success of the genetic algorithm approach in resolving school scheduling issues by seeking optimal scheduling combinations, as evidenced by achieving maximum fitness values and minimal errors (in this case, an error value of 0), indicating the absence of class schedule conflicts.

Abstract The Medan Class A Search and Rescue Office is a government agency whose main task is to carry out rescue, search and rescue operations. This agency is also a bridge for coordination with other agencies to improve the evacuation process in certain circumstances. An agency visit often occurs to this agency. Visitors or guests are often recorded in a special agenda or book which is recorded conventionally. This condition is certainly less effective because recording is still carried out using physical books which are easily damaged and often cause queues when guests register themselves. After knowing this problem, the author designed a guest book information system which was intended to fill in the features on the Medan Class A Search and Relief Office website. The goal is to fill in guest data more neatly and not cause data loss or damage. The method used in this research is the waterfall method, this method has its own specifications, so that a system can be developed according to what is desired. The way this method works is systematically and gradually so that all information and results will be recorded well and distributed accurately and quickly. The system was built using the PHP programming language with MySQL as the database.

Data mining merupakan teknik pengolaan data yang mampu menggali informasi dari kumpulan data menjadi sebuah informasi yang bermanfaat seperti halnya data penduduk miskin di Provinsi Sumatera Utara. Badan Pusat Statistik Provinsi Sumatera Utara merupakan tempat yang memiliki kumpulan banyak data penduduk miskin dari setiap wilayah yang jika diolah dengan data mining akan menghasilkan sebuah informasi baru yang berguna seperti informasi tingkat kemiskinan yang meningkat di suatu wilayah kelurahan atau desa. Kesulitan dalam proses pemfilteran kelurahan atau desa untuk mengetahui kelurahan atau desa mana yang kemungkinan berpotensi kemiskinannya meningkat. Berdasarkan permasalahan yang ada maka dibuatlah suatu sistem data mining untuk pengelompokkan kelurahan atau desa menggunakan algoritma K-Medoids. Algoritma K-Medoids merupakan proses pengelompokkan data yang mengambil titik pusat cluster dari data tersebut dan memliki karakteristik serupa satu sama lain. Sistem ini dibuat menggunakan bahasa pemrograman PHP berbasis web yang nantinya akan mengelompokkan kelurahan atau desa dengan kategori zona hijau, zona kuning dan zona merah. Tujuan dibuatnya sistem ini untuk mengetahui tingkat kemiskinan di suatu wilayah dan segera ditindaklanjuti agar meminimalisir tingkat kemiskinan di wilayah tersebut.

This study aims to design a decision support system to determine the best concrete quality using the Simple Additive Weighting (SAW) algorithm. Concrete is the primary material in construction, possessing various mechanical properties and characteristics that define its quality. At the Concrete Laboratory of Universitas Islam Sumatera Utara (UISU), the determination of concrete quality is still conducted manually, relying on subjective experience, which can lead to inconsistencies in assessment. Therefore, developing a system based on the SAW algorithm is necessary to enhance efficiency and objectivity in selecting the best concrete. The research process begins with data collection on concrete samples, covering parameters such as compressive strength, water volume, setting time, cement content, and aggregate quantity. Each criterion is assigned a weight based on its importance, followed by normalization to align scale values. The SAW algorithm is then applied to calculate the final preference values for each concrete sample, ultimately generating a recommendation for selecting the highest-quality concrete. The study results show that Concrete C achieves the highest final score (0.94706), followed by Concrete A (0.88328) and Concrete B (0.76292). The study concludes that the SAW algorithm effectively enhances objectivity and accuracy in determining the best concrete quality.
