Meningkatnya permintaan pembaharuan aplikasi berbasis open source karena seiring meningkatnya jumlah pengguna sistem operasi Linux, oleh karenanya ketika banyak pengguna linux yang melakukan permintaan pembaharuan aplikasi menyebabkan lambatnya kecepatan unduh dan membutuhkan waktu lama. Salah satu solusinya yaitu dengan membuat mirror repository linux agar memudahkan dan menawarkan koneksi pengguna yang lebih baik. Namun demikian, suatu saat ketika semakin bertambah jumlah pengguna mirror tersebut akan mengalami penurunan kualitas download hingga dapat mengalami down, sehingga tidak dapat melayani permintaan pembaharuan pengguna dengan baik. Penelitian ini bertujuan untuk merancang dan membangun Mirror Repository Linux dengan menggunakan Load-balanced Mirror Service System (LMSS) dengan mengintegrasikan beberapa MIrror Server yang dibangun secara generate melalui Manage Large Network (MLN), dengan pembagian beban menggunakan Linux Virtual Server (LVS) pada metode Network Address Translation (NAT). Sehingga beban permintaan dari client dapat ditangani Mirror Server secara bersama – sama. Dengan demikian, rata – rata waktu download dapat berkurang sebanyak 17,2 % daripada menggunakan Single Server.

IOT sebagai infrastruktur yang dirancang untuk memungkinkan benda-benda di sekitar kita dapat berkomunikasi satu sama lain, berfikir, bertindak, dan mengambil keputusan hanya dengan menggunakan perantara internet. Benda-benda tersebut tidak secara langsung dapat saling berkomunikasi dan dikendalikan, dibutuhkan suatu mekanisme yang dapat menangani jalur komunikasi serta dibangun khusus sebagai Gateway bagi lalu lintas komunikasi data. XMPP (Extensible Messaging and Presence Protocol) sebagai media komunikasi yang mendukung infrastruktur IOT dimana Protokol ini berbasis XML open-source dan mendukung banyak ekstensi yang telah di definisikan serta komunikasi real-time antar perangkat yang terdaftar pada jaringan protokol XMPP. Dalam penelitian ini dirancang sebuah gateway dengan memanfaatkan protokol XMPP agar perangkat IOT dapat saling berkomunikasi. Berdasarkan pengujian perangkat dapat berkomunikasi menggunakan gateway protokol XMPP dan melakukan proses request-response. Pada pengujian performansi saat transmisi diketahui bahwa pada kondisi transfer rate yang konstan dan ukuran data yang bervariasi memiliki rata-rata delay 9.322 ms, jitter 0.00178 ms, dan throughput 161.376 Kbps sedangkan pada kondisi transfer rate yang bervariasi dan ukuran data yang konstan memiliki rata-rata delay 25.432 ms, jitter 0.06885 ms, dan throughput 122.520 Kbps. Load server menunjukkan rata-rata penggunaan CPU 0.3% dan memory 8.0% saat perangkat dalam kondisi standby dan rata-rata penggunaan CPU 12.3% dan memory 8.0% saat transmisi data antar perangkat berlangsung. Kestabilan transmisi data dipengaruhi oleh kecepatan link antara perangkat menuju server sebagai gateway komunikasi pada protokol XMPP.

Wireless Sensor Network (WSN) adalah sebuah jaringan nirkabel yang terdiri dari satu atau lebih node bahkan berjumlah ribuan. Node dalam wireless sensor network (WSN) terdiri dari sensor node dan sink node. Penggunaan wireless sensor pada jaringan dapat membentuk sebuah node yang dapat saling berkomunikasi. Proses komunikasi pada umumnya menggunakan mekanisme pull yang didahului proses permintaan data dari sink node ke sensor  node yang menyediakan data hasil sensing. Pada beberapa arsitektur wireless sensor node, mekanisme pull ini dinilai kurang efektif karena sink node harus melakukan permintaan data terlebih dahulu ke sensor node. Sebagai alternatif, mekanisme push message dapat digunakan untuk mengirimkan data hasil sensing dalam interval waktu yang sudah pasti atau ditentukan. Dalam penelitian ini diimplementasikan mekanisme push message dengan menggunakan restful web service pada komunikasi wireless sensor. Hasil pengujian pada pengiriman data secara push didapatkan pengiriman data ke sink node secara bergantian sesuai dengan urutan alamat tujuan yang terdaftar atau tersimpan di memory sensor node. Serta dalam melakukan pengiriman data menjadi efisien tanpa adanya dilakukan permintaan data setiap saat.

IEEE 802.11b adalah standar teknologi komunikasi antar perangkat elektronik yang memanfaatkan gelombang radio frekuensi 2,4 Ghz sebagai media transmisi. Banyak jenis jaringan nirkabel yang juga memanfaatkan radio frekuensi 2,4 Ghz sebagai media transmisi, salah satunya adalah jaringan bluetooth. Jaringan bluetooth merupakan jaringan nirkabel dengan untuk komunikasi tanpa batas pada jarak yang pendek dan membutuhkan konsumsi daya yang rendah. Pertemuan 2 jaringan nirkabel yang memiliki spektrum pita frekuensi yang sama memungkinkan terjadinya penurunan performa pada jaringan nirkabel tersebut  Pada penelitian ini menguji pengaruh dari jumlah interferensi bluetooth 5.0 terhadap kinerja jaringan Wi-Fi dengan menggunakan parameter QoS Video streaming sebagai tolak ukur untuk melakukan analisis data hasil pengujian. Dari hasil analisis, dapat diketahui semakin banyak jumlah interferensi bluetooth maka nilai delay maupun nilai packet loss semakin meningkat dan nilai throughput semakin menurun. Hal tersebut menunjukkan jumlah interferensi bluetooth yang bertambah menyebabkan kinerja jaringan Wi-Fi menurun.

Teknologi yang semakin berkembang membuat kebutuhan kita akan sebuah teknologi semakin meningkat dan membuatnya menjadi efisien, akan tetapi dampak yang dihasilkan dari semua ini sangatlah besar bagi kebudayaan yang ada di Indonesia, karena menyebabkan kurangnya minat terhadap kebudayaan yang memiliki tradisi yang sangat tradisional, maupun begitu teknologi juga memiliki bagian positive yang mampu meningkatkan minat akan kebudayaan, seperti game kebudayaan, ataupun aplikasi dokumentasi kebudayaan, dan salah satunya adalah yang akan dibuat peneliti yaitu membuat AR tentang kebudayaan Lombok. AR (augmented reality) merupakan teknologi yang menggabungkan benda maya kedalam sebuah lingkungan nyata secara langsung. Aplikasi  ini akan dibangun menggunakan unity dan sedangkan untuk obyeknya akan dibangun menggunakan blender, tidak lupa membuat marker sebagai media untuk menampilkan obyek. Aplikasi ini akan digunakan pada smartphone agar mudah digunakan. Proses dalam pengujiannya akan terdiri dari dua tahap yaitu pengujian kamera dan pengujian lapangan apakah aplikasi ini diterima oleh masyarakat atau tidak.

Situs web merupakan sekumpulan dokumen Hypertext Markup Language (HTML) statis yang dibangun untuk memudahkan setiap orang berbagi informasi, selama terhubung ke dalam jaringan internet. Salah satu bagian dari sistem sebuah situs web adalah web template. Web template adalah komponen dasar dari sistem web template berguna untuk memudahkan pengembang web merancang ulang sebuah halaman web. Salah satu yang mempengaruhi kinerja halaman web yaitu loading time, dimana loading time adalah waktu yang dibutuhkan oleh browser agar dapat menampilkan halaman web secara menyeluruh oleh pengguna ketika pengguna melakukan request, selain itu loading time merupakan salah satu bagian penting dari optimasi situs web. Optimasi merupakan suatu proses dimana memodifikasi atau merubah sesuatu yang telah ada agar efektifitasnya meningkat. Dalam sebuah situs web, terdapat beberapa konsep dalam optimasi, yaitu First Paint, Time To Interactivity (TTI), First Meaningful Paint (FMP) dan Long Task. Berdasarkan penelitian-penelitian yang sudah ada, diketahui bahwa optimasi loading time web dapat dilakukan dari sisi front-end. Oleh karena itu pada penelitian ini melakukan teknik optimasi dengan menggunakan critical rendering path, above the fold, priority resource, bundle and minify, gzip, dan splitting code. Hasil dari peforma web berdasarkan metriks first meaningful paint (FMP), first contetful paint (FCP), dan time to interactivity (TTI) mengalami peningkatan rata-rata kecepatan (perosentase) yaitu FMP sebesar 73%, FCP sebesar 60%, TTI sebesar 50%, dan loading time sebesar 29%. Selanjutnya, pada resource file rata-rata ukuran file menurun sebesar 59% dan jumlah request file menurun sebesar 21%.
