Abstract

High-Performance Computer (HPC) is computer systems that are built to be able to solve computational loads. HPC can provide a high-performance technology and short the computing processes timing. This technology was often used in large-scale industries and several activities that require high-level computing, such as rendering virtual reality technology. In this research, we provide Tawaf’s Virtual Reality with 1000 of Pilgrims and realistic surroundings of Masjidil-Haram as the interactive and immersive simulation technology by imitating them with 3D models. Thus, the main purpose of this study is to calculate and to understand the processing time of its Virtual Reality with the implementation of tawaf activities using various platforms; such as computer and Android smartphone. The results showed that the outer-line or outer rotation of Kaa’bah mostly consumes minimum times although he must pass the longer distance than the closer one.  It happened because the agent with the closer area to Kaabah is facing the crowded peoples. It means an obstacle has the more impact than the distances in this case.

Abstract

Pada era digital sekarang, pemanfaatan teknologi multimedia digunakan pada berbagai bidang, terutama pariwisata. Virtual tour yang merupakan bagian dari virtual reality hadir untuk memberi manfaat ke masyarakat untuk mendapatkan pengalaman baru dengan melakukan tur secara dunia maya ke tempat wisata tertentu. Kegiatan ini menyajikan proses dan hasil dari kegiatan pengabdian masyarakat yang bekerja sama dengan Pemerintah Kota Surabaya untuk mengembangkan aplikasi virtual tour Taman Harmoni berbasis website. Dengan lima tahapan pelaksanaan, dari observasi lapangan hingga dokumentasi, kami dapat mempublikasikan aplikasi tersebut dengan laman web yang bisa diakses oleh masyarakat dimanapun dan kapanpun. Sebanyak 71,4% pengunjung aplikasi yang telah mengeksplorasi fitur-fitur yang disediakan memberikan umpan balik yang baik terhadap keberadaan aplikasi ini.

Abstract

Weather classification is crucial in various sectors, including agriculture, transportation, and disaster management. Accurate weather prediction can help mitigate risks and improve decision-making in these fields. However, classifying weather conditions remains challenging due to the complex and dynamic nature of meteorological data. This study aims to compare different machine learning classification methods to determine the most effective model for weather classification. The research employs a structured methodology consisting of seven key steps: literature study, data understanding, exploratory data analysis, data preparation, modeling, evaluation, and hyperparameter tuning. The study used Decision Tree, Random Forest, Support Vector Machine, K-Nearest Neighbors, Gradient Boosting, AdaBoost, and Extra Trees to identify the best-performing classifier. Model evaluation was conducted using accuracy, precision, recall, and F1-score. The results indicate that Gradient Boosting achieved the highest performance, surpassing other models with an accuracy of 90.15%. To optimize the model further, hyperparameter tuning was conducted using GridSearchCV, and feature selection was done using SelectKBest. This process resulted in an improved accuracy of 90.22%, demonstrating the effectiveness of model optimization.
