Abstract

The advancement of information technology in the era of globalization has opened up new business opportunities through electronic transactions. This is regulated in Law Number 7 of 2014 concerning Trade, which drives the rapid development of e-commerce. The internet and information technology, especially Android devices, have changed people's shopping patterns as well as the way manufacturers promote their products. An example is Rfour Clothing, a fashion business from Wonogiri that focuses on selling truck-themed t-shirts. To overcome the obstacles in offline sales methods and untidy transaction recording, researchers developed an Android-based application for Rfour Clothing with the Rapid Application Development (RAD) method that presents online ordering features, payment gateways, and web based admin dashboards used to manage goods and manage transaction results, so that they can support future business growth; further research is recommended to improve the quality of the interface, add notification features, and strengthen application security to provide a user experience

Abstract

Kesehatan merupakan salah satu dari parameter kesejahteraan manusia. Jika seseorang sakit, mereka akan mencoba memeriksakan diri ke dokter. Banyak penyakit memiliki gejala yang tidak spesifik, karena itu perlu pengetahuan untuk mendiagnose sebuah penyakit. Dokter merupakan faktor kunci dalam sistem pengobatan. Usia, gaya hidup dan polutan dapat menyebabkan penyakit degeneratif. Para degeneratif memerlukan perhatian seksama dengan pemantauan rutin. Sistem pengobatan konvensional masih membutuhkan interaksi dengan dokter secara langsung. Para dokter mendengarkan keluhan, bertanya, mendiagnosa, dan memberikan perawatan medis. Di sisi lain dengan terbatasnya jumlah dokter, distribusi yang tidak merata, dan jarak yang jauh menyebabkan praktek medis konvensional tidak efisien. Dokter dapat menerima hasil, mendiagnosa dan memberikan saran secara jarak jauh menggunakan teknologi informasi dan komunikasi. Layanan ini dapat mencakup pula kasus-kasus darurat dan layanan pendampingan.Berdasarkan masalah di atas, tujuan penelitian ini adalah terutama untuk merancang dan membangun aplikasi yang dapat digunakan untuk komunikasi antara dokter dan pasien berbasis pada jaringan TCP/IP. Penekanan aplikasi dalam berbagai data yang dikirim (teks, audio, video dan file).Sistem pemeriksaan secara jarak jauh dapat diwujudkan dengan menggunakan bahan dan alat yang telah dikenal dengan baik oleh pengguna umum. Kesulitan untuk mengakses alamat IP dalam sistem ini dapat ditangani oleh penambahan jalur khusus virtual semisal Hamachi. Kecepatan komunikasi melalui LAN memberikan hasil sangat baik, memenuhi persyaratan  hampir semua fasilitas yang ada, sedangkan kecepatan komunikasi melalui internet sudah cukup untuk beberapa persyaratan sistem terutama yang yang tidak memerlukan kemampuan real-time.

Abstract

Mount Kerinci is one of the highest mountains in Indonesia that attracts many climbers every year. Proper management of climbing quotas is needed to maintain a balance between the number of climbers and environmental sustainability. However, the manual system currently used often causes uncertainty in quota availability, overbooking, and errors in calculation. To overcome this problem, this study develops an Android-based mobile application that uses the Rapid Application Development (RAD) method for booking climbing e-tickets. This application is designed to provide transparency and efficiency in managing climbing route quotas, allowing climbers to book tickets in real-time and helping managers manage quotas more effectively. This innovation is expected to optimize climbing quota management and improve the climber experience

Abstract

Rapid technological developments have changed the process of searching for boarding houses, which has been done manually through brochures, pamphlets, or banners. These conventional methods are considered inefficient because of their limited reach and the time required, especially for prospective tenants from outside the area. This study designs and develops a mobile-based e-boarding house application with features such as searching, booking, and digital payments, using the Rapid Application Development (RAD) methodology. This application makes it easier for users to find boarding houses that suit their wishes while making it easier for boarding house owners to manage room availability, tenant data, and payment history in a structured manner. The test results show that the e-boarding house application runs optimally without technical constraints and is effective in meeting user needs. By providing digital solutions, this application can increase the efficiency of searching and managing boarding houses, so that the process becomes faster, more practical, and more modern. Implementing this system provides significant benefits for prospective tenants and boarding house owners, namely increasing accessibility and management in the boarding house industry.

Abstract

Subjectivity in manual quality control for traditional roof tiles poses a significant challenge, as the current process relies on manual, visual inspection and subjective judgment. This research proposes an automatic system to classify tile quality from images using a Convolutional Neural Network (CNN), specifically the EfficientNet-B0 model enhanced with transfer learning. The study utilized a primary dataset comprising 616 local roof tile images collected directly from producers in Berjo Kidul, Godean, Yogyakarta. These images were manually labeled based on producer criteria into three distinct classes: 'Finished' (203 images), 'Underbaked' (213 images), and 'Broken/Cracked' (200 images). The methodology involved resizing all images to 224x224 pixels and applying data augmentation, including random rotation, horizontal flipping, and color jitter, to mitigate overfitting. The EfficientNet-B0 model, pre-trained on ImageNet, was implemented in PyTorch and trained for 10 epochs using an 80/20 train/validation split with the Adam optimizer. The model demonstrated outstanding performance, reaching 99.70% accuracy in validation. Further evaluation confirmed this robustness; the model perfectly identified the 'Underbaked' class and recorded only a single misclassification error on the test set. Qualitative analysis via a Flutter mobile application showed the system is resilient to changes in background and viewing angles, although its accuracy is compromised by poor lighting and strong shadows. This study validates the proposed system as a highly efficient and objective tool for a more reliable quality control process.

Abstract

Kenzy Toys merupakan usaha ritel yang bergerak dalam penjualan mainan anak-anak. Proses pencatatan transaksi dan pengelolaan keuangan sebelumnya masih dilakukan secara manual, sehingga berpotensi menimbulkan kesalahan dalam pencatatan laba, perhitungan gaji, dan pengelolaan data karyawan. Untuk meningkatkan efektivitas dan akurasi pengelolaan data, dikembangkan sistem informasi keuangan berbasis web dan mobile yang terintegrasi dengan basis data cloud menggunakan Supabase sebagai media penyimpanan. Penelitian ini menggunakan metode pengembangan sistem model Waterfall, yang terdiri dari tahap analisis kebutuhan, perancangan, implementasi, dan pengujian. Aplikasi mobile dikembangkan dengan Flutter, sedangkan aplikasi web menggunakan Next.js dan TypeScript. Sistem yang dihasilkan dilengkapi dengan fitur pencatatan pembelian, penjualan, pengeluaran, dan pemasukan, serta penggajian otomatis yang terintegrasi dengan payment gateway Xendit. Hasil pengujian dengan metode black box menunjukkan seluruh fitur berjalan sesuai fungsi yang diharapkan. Berdasarkan hasil tersebut, sistem ini dinilai mampu membantu pemilik usaha dalam mengelola keuangan, memantau aktivitas karyawan, dan menyusun laporan keuangan secara lebih efisien dan terstruktur.
