Abstract

Sistem operasi mengelola sumber daya perangkat keras dan menyediakan antarmuka pengguna. Windows 8 masih sangat relevan untuk dikaji karena mewakili transisi arsitektur yang krusial dari antarmuka desktop klasik (Windows 7) ke antarmuka modern berbasis tile (Windows 10/11). Karakteristik transisional grafis (Metro UI) ini menjadikannya objek uji beban yang ideal bagi hypervisor tipe 2 dalam menangani sistem operasi guest.Berbeda dengan penelitian terdahulu yang umumnya mengandalkan konfigurasi tunggal, penelitian deskriptif-kuantitatif ini mengevaluasi performa instalasi dan konsumsi sumber daya Windows 8 pada Oracle VM VirtualBox melalui skema multi-konfigurasi. Pengujian membandingkan alokasi RAM guest sebesar 2 GB dan 4 GB, di mana setiap skenario direplikasi tiga kali guna mendapatkan nilai rata-rata yang valid. Performa host dipantau secara simultan selama instalasi menggunakan Windows Task Manager dan Resource Monitor.Hasil pengujian menunjukkan perbedaan performa yang signifikan. Konfigurasi RAM 2 GB mencatatkan rata-rata durasi instalasi 20,5 menit dengan puncak utilitas CPU host 93,4%, serta ukuran aktual Virtual Disk Image (VDI) pasca-instalasi 12,5 GB. Sementara itu, konfigurasi RAM 4 GB lebih efisien dengan durasi 17,2 menit, puncak CPU 89,1%, dan ukuran VDI 12,8 GB. Data ini membuktikan bahwa penambahan RAM guest mampu mempercepat proses paging dan menekan beban kerja subsistem memori virtual, meskipun beban CPU tetap dominan pada fase dekompresi berkas biner.Penelitian ini memberikan kontribusi berupa data komparatif kuantitatif yang objektif. Temuan tersebut dapat diimplementasikan sebagai rujukan praktis bagi para pengajar dan mahasiswa untuk menentukan alokasi sumber daya minimum yang paling optimal saat menjalankan praktikum virtualisasi sistem operasi legacy pada infrastruktur laboratorium yang terbatas.

Abstract

Operating system installation skills are a crucial core competency in the field of information technology. However, the learning process often faces challenges related to limited technical documentation and the risk of damage to the host computer system. This study aims to comprehensively describe the procedural steps for installing the open-source Linux Mint operating system using the Oracle VirtualBox virtualization platform, while also analyzing the operational relationship between the two. The method used was a laboratory experiment testing the installation on a virtual machine configured with 3 GB of RAM, a 2-core CPU, and 30 GB of storage on mid-range hardware. The results showed that the installation process was successful, smooth, and stable, taking between 30 and 45 minutes. Post-installation testing confirmed that all desktop interface functionalities and navigation menus responded normally to user interactions without any errors. This study concludes that the combination of Linux Mint and VirtualBox has proven to be a secure, flexible, and effective “safe-sandbox” testing environment for teaching operating system basics to novice users.

Abstract

Mobil pembersih otomatis memerlukan sistem yang mampu memberikan informasi posisi terbaru selama alat beroperasi. Masalah utama penelitian ini adalah belum tersedianya mekanisme pemantauan sederhana dan mandiri untuk mengetahui posisi serta status kerja kendaraan tanpa bergantung pada server eksternal. Penelitian ini bertujuan mengembangkan prototipe pemantauan tertanam pada kendaraan otonom dengan menggunakan mikrokontroler, modul penentuan posisi satelit, dan tampilan lokal. Penelitian menggunakan metode Research and Development yang dipadukan dengan model analisis, perancangan, pengembangan, implementasi, dan evaluasi. Evaluasi meliputi pengujian fungsional, pengujian kestabilan selama tiga puluh menit, pengujian penentuan posisi satelit pada area terbuka, semi terbuka, dan tertutup, pengujian tampilan, pengoperasian kendaraan, serta simulasi interval pencatatan. Pengendali berhasil memproses data posisi dan menampilkan lintang, bujur, waktu pembacaan, serta status sinyal. Pada area terbuka, seluruh sepuluh percobaan menghasilkan data valid dalam waktu dua puluh sembilan sampai enam puluh lima detik. Area semi terbuka membutuhkan waktu enam puluh satu sampai seratus lima belas detik dan menghasilkan dua percobaan yang kurang stabil. Area tertutup menghasilkan data tidak stabil atau tidak valid dalam waktu seratus tiga puluh sampai dua ratus dua puluh detik. Interval lima detik menghasilkan 120 data simulasi selama sepuluh menit. Hasil tersebut menunjukkan bahwa hambatan lingkungan sangat memengaruhi kinerja penentuan posisi satelit, sedangkan daya stabil dan sambungan kuat mendukung pengoperasian berkelanjutan. Prototipe sesuai untuk pemantauan posisi umum, tetapi belum sesuai untuk navigasi berpresisi tinggi. Penelitian selanjutnya perlu menguji penyimpanan jangka panjang dan pemantauan berbasis peta.
