The paper presents research into the analysis of queuing systems in the context of communication, with the goal of creating precise models and evaluating their efficacy. The importance of queueing systems cannot be overstated in fields as disparate as telecommunications, computer networks, and the service sector. Analyzing how these systems function allows us to better allocate resources, boost performance, and provide a better experience for end users. The main goals are to create mathematical models that precisely capture the queuing behavior and to assess the effectiveness of these models in terms of metrics like queue length, waiting time, and system utilization. To do so, it is necessary to perform an extensive analysis of the relevant literature and theoretical frameworks. The properties of communication-related systems are examined, and many queuing models, including the M/M/1, M/M/c, and M/G/1, are modified accordingly. In addition, simulation methods are used to verify the accuracy of the suggested models and assess how they would fare in practical applications. The research yields useful information on the dynamics of queuing systems used in the field of communication. They show how changes to the arrival rate, service rate, and number of servers affect the system's most important performance indicators. Different scheduling policies, routing tactics, and resource allocation methodologies are also investigated to determine their impact on system performance.

Smartphones are the latest technology from ordinary cellphones which are in great demand because with current technological advances many people need smartphones for their daily needs such as work, education and others. Many buyers are confused about which smartphone to buy because of the many brands and types of smartphones being marketed.

This research aims to produce recommendations as well as Smartphones to buyers. Decision Support System (SPK) uses the Simple Additive Weighting (SAW) method. This Smartphone Selection Decision Support System is implemented in the form of a web. In this system, users can input smartphone criteria that suit their needs with the Smartphone Recommendation Support System making it easier for buyers to buy smartphones according to their needs.

Design Of A Semi-Automatic Bread-Making Machine Including Medium Capacity With A Variety Of Baking Temperatures

Thu, 12 Oct 2023 05:21:00 SE Asia Daylight Time

The bread machine is also a leverage to increase production capacity and production quality. In contrast to manual bread production, which requires a lot of effort and time, a bread machine makes everything more efficient. The bread machine's output is better than manual production's. Besides that, the hygiene of the bread produced is guaranteed. The device is sterile and safe because all materials are protected with stainless plates, a mixer motor flame that can be adjusted according to needs, and an automatic oven according to requirements. The tray uses hygienic, not harmful to health, and environmentally friendly and pollution-free materials. The level of safety in use is higher because it has appropriate dimensions. The technique for operating a semi-automatic bread-making machine with a production capacity of 4 kg requires 45 minutes with an oven process temperature of 100 ºC to 150 ºC.

Rancang Bangun Vertical Axis Wind Turbine (VAWT) Dengan Pendekatan Metode Ergonomic Function Deployment (EFD)

Thu, 12 Oct 2023 05:21:44 SE Asia Daylight Time

VAWT adalah turbin angin sumbu vertikal yang gerakan poros dan rotornya sejajar dengan arah angin. Sehingga VAWT dapat bergerak tanpa bergantung pada arah angin. Selain itu VAWT juga dapat bergerak pada kecepatan angin rendah dan menghasilkan listrik karena VAWT memiliki torsi yang tinggi. Tujuan dari penelitian ini adalah VAWT dirancang dengan menggunakan Metode Ergonomic Function Deployment dengan menggunakan tabel House of Ergonomic. Hasil penelitian didapatkan sebuah rancangan VAWT yang ergonomis dengan menggunakan 6 sudu dengan skala pipa paralon 8 dim setelah melalui screening dan selecting concept pada table morphological chart.

Warehouse Management System Design at PT XYZ

Thu, 12 Oct 2023 00:00:00 SE Asia Daylight Time

The warehouse is one of the most important parts of a company. Ineffective warehousing processes can disrupt warehouse operations. Recording warehouse transactions that are done manually will require checking one by one on the hardcopy form that has been stored. Therefore, this internship program aims to improve the performance of warehousing operations at PT XYZ. The method used in the analysis is data collection and application system design using the prototype method. The data is taken based on the results of interviews and observations in the warehouse. This activity creates a web-based warehouse management system application to help control incoming and outgoing inventory. The system built makes it easy for administrators to see the number of items made for each event. The results of black box testing show that the application has 100% functionality. The test results illustrate that the application functions properly according to user needs and has been accepted by PT XYZ
