Abstract

Basic Physics Laboratory is one of the supporting laboratories at Gunadarma University. Each practical activity in the laboratory is supervised by respective assistants. Therefore, a support system is needed as a basis for decision-making in determining assistant candidates. This decision-making process is processed using data mining techniques, specifically classification algorithms. The criteria or attributes used in the decision-making process include written test scores, practical test scores, presentation scores, equipment usage abilities, and interviews. The classification algorithms used in this research are ID3 and C4.5 algorithms. The tools used to implement these algorithms are RapidMiner Studio 9.10. These algorithms will generate decision trees that can be used as decision support. The aim of this research is to conduct an accuracy comparison analysis for the ID3 and C4.5 algorithms. The highest accuracy obtained will be used as a reference for determining whether assistant candidates are accepted or not. The accuracy results show that the C4.5 algorithm has the highest accuracy, precision, and recall compared to the ID3 algorithm. The determination of the highest value is done using the k-fold cross-validation model for values 2, 4, 6, 8, and 10. The C4.5 algorithm has the highest accuracy of 96.67% at k-fold value = 2.

Abstract

JerseyBolaku distro in Jatiasih, sells conventional and custom jersey. Marketing their products using conventional methods where customers come to see the product and make transactions. The owner wants product promotion, by word of mouth and through social media. The owner do manual bookkeeping by recording every incoming and outgoing product, so there is duplicate and inappropriate data. This makes owners changed the marketing strategy from conventional to digital. The purpose of this research is to distribution using digital marketing. The digital marketing strategy made by owners, used e-commerce website, where it can be accessed by customers anywhere using a smartphone. Customers need access the website if they want to view products and make transactions. Owners find it easy to view sales reports in each period. The method used in making the website is the SDLC method with a prototyping model. The steps taken in the prototyping model is to identifying needs and problems of user, hardware, software, determining the programming language, designing user interfaces for admins and users are using UML diagrams, the prototypes website need to be evaluated before launching and do evaluating and improving if any problems when tested and finally launched the system to be implemented. Website testing is done by using black box testing to test the functionality of the website. Website running successfully using Internet Explorer on PC and smartphone. Website successfully hosted, customers can view and order products more easier and faster. The owner can record sales transactions and record products in more detail.

Abstract

Transformasi digital di dunia pendidikan merupakan peluang sekaligus tantangan yang mengharuskan adaptasi terhadap kemajuan teknologi, termasuk dalam pengelolaan nilai akademik siswa. Sekolah Imam Nawawi Boarding School (INBS) Putra – Cibinong menghadapi kendala dalam pengolahan nilai dan pembuatan rapor yang masih dilakukan secara manual, sehingga berpotensi menimbulkan kesalahan dan memakan waktu signifikan. Untuk mengatasi hal tersebut, Tim Abdimas Universitas Gunadarma melaksanakan pelatihan penggunaan Google Sheets sebagai solusi digital. Pelatihan ini bertujuan membekali guru dengan keterampilan mengelola data akademik siswa secara lebih cepat, akurat, dan profesional melalui fitur otomatisasi seperti formula, filter, dan kolaborasi real-time. Evaluasi pelatihan menunjukkan bahwa 82% peserta menganggap program ini sangat bermanfaat dalam meningkatkan efisiensi kerja. Selain itu, kegiatan ini berhasil mendorong para guru untuk lebih aktif berkontribusi dalam transformasi digital di lingkungan pendidikan. Pelatihan ini juga memberikan dampak positif dalam menciptakan lingkungan belajar yang lebih efisien dan berbasis teknologi.
