ion built is a website-based application that can be accessed using a web browser. To make application design in this research, UML modeling is used. The model that has been designed using UML will be implemented into PHP coding which can then be run via a web browser. The supporting tools used are XAMPP which provides apache and mysql services. From the test results, it is found that the application of apriori algorithm based on this website is able to perform calculations using the a priori algorithm accurately. These results are proven by comparing the results obtained from manual calculations with the results of calculations performed by this application using a sample of the same data.

Abstrak: Dalam jurnal ini dijelaskan bagaimana merancang hingga membangun sebuah aplikasi yang dapat melakukan perhitungan dengan menggunakan algoritma apriori. Adapun alur kerja yang diterapkan dalam penelitian ini adalah alur kerja yang berurutan (metode waterfall). Aplikasi yang dibangun adalah aplikasi yang berbasis website yang dapat dikases menggunakan web browser. Untuk membuat perancangan aplikasi dalam penelitian ini, digunakan pemodelan UML. Model yang telah dirancang dengan menggunkan UML akan diimplementasikan kedalam koding PHP yang nantinya dapat dijalankan melalui web browser. Adapun tools pendukung yang digunakan adalah XAMPP yang menyediakan service apache dan mysql. Dari hasil pengujian didapatkan bahwa aplikasi perhitungan algoritma apriori berbasis website ini mampu melakukan perhitungan dengan menggunakan algoritma apriori secara akurat. Hasil ini dibuktikan dengan cara membandingkan hasil yang didapat dari perhitungan manual dengan hasil perhitungan yang dilakukan oleh aplikasi ini dengan menggunakan sebuah sampel data yang sama.

Abstract:CV Kurnia MebeI Indah is a furniture industry engaged in the production and sale of household furniture. The existing sales system is still conventional, namely consumers must come directly to the showroom. This can hinder…
er sales for potential customers who are out of town. In addition, the input of customer data, product data, and transaction data is still not stored properly and neatly because it still uses manual paper records. In this study, the authors built a web-based sales application (e-commerce) using the codeigniter framework. The method used in software development is the waterfall method, which in this method, starts from analyzing needs, system and software design, coding, testing, and program implementation. The result of this research is the implementation of a web-based sales system (e-commerce) at CV. Kurnia Mebel, can be used as a means of sales that can be accessed online anywhere and anytime, the purchase process can be done directly without having to come to the showroom, and can facilitate the storage of customer data, products, and company transactions.
Abstract:The Sarto Sapi Company is one of the providers of cattle sales services which is located in Jebol Hamlet RT 001 RW 007, Donohudan, Regency Boyolali, with sales still done manually. Objective The research is the development…
nt of a website-based online sales information system for the Sarto Sapi Company to facilitate access for customers who want to shop online without having to come directly to the Sarto Sapi Company. The website developed is a means of selling cattle as well as a means of conveying information to the public. The method used in developing a website-based online sales information system at the Sarto Sapi Company is the Waterfall method. The Waterfall method is used to determine system requirements, the next step is the analysis, design, coding, testing and maintenance stages. Development of a Website-Based Online Sales Information System at the Sarto Sapi Company, researchers used notepad++ software, sublime text, the PHP programming language, and MySQLi database. Results of research on developing a website-based online sales information system at the Sarto Sapi company, online sales website. National Journal Research Output
Abstract:Penelitian ini bertujuan mengidentifikasi pola pengelompokan komponen perakitan komputer menggunakan metode K-Means Clustering. Dataset yang digunakan mencakup CPU, motherboard, RAM, GPU, PSU, dan casing. Proses penelitian…
an meliputi eksplorasi data, pembersihan data, imputasi nilai hilang, encoding kategorikal, normalisasi, serta rekayasa fitur seperti total TDP dan rasio daya PSU. Hasil clustering menunjukkan pembentukan empat kelompok utama, yaitu komponen low-end, mid-range, high-end, dan cluster RAM yang berdiri sendiri. Temuan ini membuktikan bahwa K-Means efektif dalam memetakan karakteristik hardware dan dapat digunakan sebagai dasar sistem rekomendasi perakitan PC.
Abstract:This study aims to identify the dominant error patterns of students in geometry learning based on Newman's Error Analysis (NEA) and to examine their implications for readiness to understand Non-Euclidean Geometry. The method…
thod employed is a Systematic Literature Review (SLR) of 10 empirical articles published between 2019 and 2026. Data were extracted based on the five stages of NEA — reading, comprehension, transformation, process skill, and encoding — and subsequently analyzed through narrative synthesis, percentage comparison, and descriptive effect size. The results indicate that comprehension errors and encoding errors are the most dominant categories, with the highest percentages of 56.92% and 50%, respectively, followed by transformation errors, which consistently fall within a moderate effect range (20–40%), while reading errors and process skill errors are classified as low. The primary causes of errors include weak understanding of geometric concepts, inability in spatial visualization, limited mathematical language, and lack of procedural precision. The findings contribute as a diagnostic foundation for designing more effective geometry learning, while simultaneously serving as a conceptual bridge toward higher-level geometry
Abstract:Keterampilan coding telah menjadi bagian penting dalam pengembangan kemampuan berpikir logis dan kreatif sejak usia dini. Namun, belum semua guru sekolah dasar memiliki pemahaman dan keterampilan yang cukup untuk mengajarkan…
rkan coding kepada siswanya. Pengabdian ini bertujuan untuk memberikan pelatihan pembelajaran Coding for Kids kepada para guru di SD Brainfor Islamic School. Kegiatan dilaksanakan pada bulan Mei 2025 dengan pendekatan pemaparan materi dan praktik langsung. Materi mencakup pengenalan konsep dasar coding, manfaatnya dalam pendidikan dasar, serta pengenalan berbagai tools yang sesuai untuk anak usia SD kelas 1 sampai 6. Salah satu tools yang diperkenalkan dan dilatihkan adalah Scratch, sebuah platform visual yang intuitif dan ramah anak. Hasil kegiatan menunjukkan bahwa lebih dari 85% peserta pelatihan mampu memahami konsep dasar coding dan mengimplementasikan Scratch dalam rencana pembelajaran mereka. Kegiatan ini diharapkan menjadi langkah awal dalam membekali guru-guru dengan kompetensi digital yang relevan untuk kebutuhan pembelajaran dimasa depan.
