Abstract

Poor indoor environmental conditions are often associated with reduced concentration, lower motivation, and decreased productivity in office settings. Addressing this issue requires a systematic assessment of Indoor Environmental Quality (IEQ) and its contribution to work performance. This study examines the effect of Indoor Environmental Quality (IEQ) on office worker performance, focusing on five components: Indoor Air Quality (IAQ), Thermal Comfort, Lighting Quality, Acoustic Quality, and Occupant Experience. The Best-Worst Method (BWM) was applied to determine the relative importance of these factors through a combination of subjective surveys and objective weighting using linear programming. Results indicate that Occupant Experience, particularly ergonomic improvements such as adjustable furniture and optimized layouts, has the strongest influence on productivity. Thermal Comfort ranks second, followed by Lighting Quality, Acoustic Quality, and IAQ. Sensitivity analysis confirms the robustness and consistency of the findings. This research contributes by offering a systematic weighting of IEQ factors, highlighting the central role of ergonomics in workplace design. The study emphasizes that integrating ergonomic and environmental considerations is essential to improve worker performance. The novelty of this study lies in integrating Occupant Experience into the BWM framework, providing a more comprehensive model of IEQ and offering new insights for designing healthier and more productive office environments.

Abstract

Greedy Perimeter Stateless Routing (GPSR) merupakan protokol routing yang memiliki performa baik di lingkungan VANET. Protokol GPSR memiliki kelemahan ketika node selanjutnya mengalami keadaan local maximum, yaitu ketika node selanjutnya tidak dapat mengirim paket ke node selanjutnya dikarenakan tidak ada node di sekitar yang memiliki posisi terdekat dengan node tujuan atau semua node terdekat sudah pernah menerima paket tersebut. Untuk mengatasi keadaan local maximum, protokol GPSR dimodifikasi dengan konsep overlay network. Overlay network diterapkan dengan menggunakan route discovery milik protokol dynamic source routing (DSR). Hasil dari proses route discovery akan menjadi acuan pencarian virtual anchor point (VAP). VAP merupakan representasi dari overlay network dan berguna untuk mengganti acuan posisi node tujuan dalam metode greedy forwarding. Selain VAP, pemilihan node selanjutnya menerapkan metode area optimum dalam pemilihan node selanjutnya untuk menghindari node yang berada pada luar batas transmisi node pengirim. Dalam makalah ini, evaluasi dilakukan terhadap kinerja routing protocol pada skenario real. Hasil simulasi diukur berdasarkan nilai rata-rata packet delivery rasio (PDR), end to end delay dan routing overhead (RO). Jumlah node yang digunakan dalam simulasi dimulai dari 50, 100, dan 150 node. Dari simulasi yang dilakukan didapatkan bahwa real performa GPSR modifikasi dibandingkan dengan GPSR tradisional mengalami peningkatan nilai PDR sebesar 72%, tetapi terjadi peningkatan pada nilai rata-rata end to end delay sebesar 1118% dan peningkatan nilai rata-rata RO sebesar 0.6%.

Abstract

VANETs (Vehicular ad hoc networks) merupakan teknologi yang digunakan untuk komunikasi antar kendaraan. Dalam VANETs, kendaraan bergerak dengan kecepatan tinggi dan arah yang berbeda-beda, sehingga menyebabkan jaringan komunikasi yang telah terbentuk berubah dengan cepat. Salah satu contoh protokol routing yang sering digunakan dalam komunikasi VANETs adalah GPSR. Greedy perimeter stateless routing (GPSR), routing protokol baru untuk jaringan nirkabel yang menggunakan informasi posisi node tujuan untuk membuat keputusan penerusan paket. Topologi jaringan VANETs yang sangat dinamis menyebabkan komunikasi antar node tidak stabil. Node next hop yang telah dipilih mungkin telah keluar dari jangkauan transmisi sebelum menerima paket. Penelitian ini bertujuan untuk memecahkan masalah dalam protokol routing GPSR terkait ketidakstabilan komunikasi karena posisi node yang berubah dalam mode greedy forwarding. Dalam penelitian ini penulis menambahkan set parameter yang digunakan untuk mengambil keputusan routing dengan memasukkan faktor kecepatan dan arah pergerakan kendaraan. Setiap node akan melakukan penghitungan rata-rata geometrik kecepatannya sebelum penyiaran beacon message. Informasi rata-rata geometrik tersebut akan ditambahkan pada beacon message. Setelah node menerima paket beacon message, node akan memperbarui informasi yang terdapat pada neighbor table. Pada penelitian ini, neighbor table juga menyimpan informasi posisi node pada waktu sebelumnya dan informasi rata-rata geometrik kecepatan. Informasi dalam neighbor table tersebut akan digunakan dalam pengambilan keputusan routing. Penelitian ini juga melakukan modifikasi pada metode penerusan paket greedy forwarding. Jika penerusan paket menggunakan metode greedy forwarding, tahapan pertama yang dilakukan adalah menemukan node-node yang berada dalam area komunikasi optimum. Selanjutnya dari node-node yang berada pada area komunikasi optimum, akan dilakukan seleksi pemilihan forwarding node. Node yang layak menjadi forwarding node adalah node yang paling minimal perbedaan rata-rata geometrik kecepatannya dan bergerak mendekati node tujuan. Diharapkan dengan penelitian ini dapat meningkatkan performa protokol routing GPSR

Abstract

State Drive (SSD) is an alternative to data storage that is popular today, widely used as a media cache to speed up data access to the hard disk (HDD). This paper proposes page replacement technique on SSD cache that used frequency and recency parameter, alternately. The algorithm is selected adaptively based on trace input. This method helps to overcome changes in access patterns while minimizing the number of write processes to SSD. The proposed algorithm can choose a replacement technique that suits the user access pattern so that it can bring a better hit rate. The proposed algorithm is also integrated with the ghost-cache mechanism so that the reduction in the number of writing processes to SSD is significant. The experiment runs using a real dataset, describing trace of data read, and data write taken from real usage. The trial shows that the proposed algorithm can give good results compared to other similar algorithms.

Abstract

Energy limitations are the problem that gets the most attention in the term of Wireless Sensor Networks (WSN). Sleep wakeup scheduling method is one of the most efficient techniques to increase sensor node operational time on WSN. However, in the target-based WSN environment with p-coverage and q-connectivity models, the use of wake-up scheduling has to consider the constraints on the number of connectivity on the sensor and coverage on the target. Genetic Algorithm is a solution to the problem of sleep-wake scheduling with multi-objective problems. This study proposes a new method of sleep wakeup scheduling based on Genetic Algorithm for energy efficiency in target-based WSN with p-coverage and q-connectivity models. This new method uses the sensor range, connectivity range and energy as an objective function of the fitness function in the Genetic Algorithm. With the presence of energy as a factor of the objective function can increase energy efficiency in target-based WSN with p-coverage and q-connectivity models.
