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

Universitas Teknologi Yogyakarta (UTY) operates several computer laboratory rooms used daily by students according to their scheduled times. Sometimes, these rooms experience sudden schedule changes, causing conflicts with other room bookings. This research aims to employ an Augmented Reality (AR)-based application for monitoring the dynamic schedule of lab room usage. The method utilizes a marker-based AR application, tested through black box implementation. The application successfully reads markers at distances of 10–90 cm, tilt angles of 10–80 degrees, and light intensities ranging from 40 to 250 lux. Under these conditions, the markers are readable, and the application responds by displaying virtual objects. Users of the lab rooms can utilize this AR application to identify changes in the scheduled usage plans at UTY as they occur.

Abstract

The tourism industry in Indonesia continues to grow with the increasing interest of tourists in destinations offering authentic experiences. One of the challenges in this industry is the need for a fast and efficient reservation system, particularly for homestays, which are becoming increasingly popular. This study aims to develop an Android-based reservation application for accommodation and vehicle rentals using the Rapid Application Development (RAD) method. The application is designed to provide convenience for tourists in booking accommodations and vehicles, as well as providing information on attractions around the accommodation. Additionally, a web-based admin dashboard was developed for administrators to manage reservation data more efficiently. The RAD method was chosen because it can accelerate the development process by going through the planning, design, construction, and cutover stages. The results from testing using the Black Box technique show that the application functions as expected. The application successfully implements features for reservations, vehicle rentals, and nearby attraction information, while integrating the Midtrans Payment Gateway to facilitate transaction processes.

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

Penentuan tingkat kematangan Tandan Buah Segar (TBS) kelapa sawit secara konvensional masih bergantung pada pengamatan visual manual yang bersifat subjektif dan rentan terhadap inkonsistensi, sehingga berpotensi menurunkan rendemen minyak. Penelitian ini bertujuan mengembangkan sistem klasifikasi kematangan buah sawit yang akurat, ringan, dan mampu beroperasi sepenuhnya secara offline pada perangkat mobile menggunakan implementasi MobileNetV2. Metode yang digunakan adalah transfer learning yang dioptimasi melalui teknik Post-Training Quantization ke dalam format TensorFlow Lite. Model dilatih menggunakan dataset citra lapangan dari Kalimantan Timur yang diperluas melalui augmentasi data dan diintegrasikan ke dalam aplikasi berbasis Flutter. Hasil pengujian menunjukkan model mampu mencapai akurasi 89,0%. Proses kuantisasi berhasil mereduksi ukuran model secara signifikan sebesar 84,6% (dari 13 MB menjadi 2 MB) dan menghasilkan latensi inferensi rata-rata 120 ms pada perangkat Android kelas menengah. Kesimpulan dari penelitian ini membuktikan bahwa integrasi model CNN ringan yang dikuantisasi merupakan solusi praktis dan efisien untuk mendukung penerapan pertanian cerdas di lingkungan dengan sumber daya terbatas.

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.
