Abstract

This study discussed the design and implementation of load balancing of two WANs so that the traffic load and bandwidth provided by both WANs could be used equally. The methods used in this research were observation and identification, network topology design, implementation, and testing. This study found that load balancing could divide the network load to all available gateways so that there was no overload on the network used by visitors. After implementing load balancing, the network throughput parameter increased 1.51% compared to the Indihome 1 network and 7.5% compared to the Indihome 2 network. The packet loss parameter increased by 99% compared to the Indihome 1 network and increased 90% compared to the Indihome 2 network. Network delay decreased by 1.33% compared to the Indihome 1 network, and decreased by 1.5% compared to the Indihome 2 network. The Network jitter parameter decreased by 0.93% compared to the Indihome 1 network and decreased by 1.54% compared to the Indihome 2 network.

Abstract

Unequal bandwidth distribution between clients that are used for online tests will cause the quality connection among clients to differ. Especially when some client dominates the bandwidth. The other client will suffer to have a proper connection. Using Queue Tree bandwidth management with the type of Per Connection Queue (PCQ) the distribution of bandwidth can be done evenly among clients. The implementation of PCQ Queue Tree is able to reduce the length of ping time by 90% from 134 ms and 13 ms. Delay is decreased 47% from 17 ms to 9 ms with a very good category. Jitter decreased 41% from 17 ms to 7 ms with a very good category. Throughput increased 53% from 234.582 Kbps to 503.584 Kbps in the medium category. Meanwhile, in the packet loss parameter, there is no difference in conditions before and after the implementation of PCQ Queue Tree because there is no packet loss during the test, which means packet loss condition is in the very good category.

Abstract

The weather prediction tool is a microcontroller-based automatic weather monitoring tool that can monitor changes in temperature, humidity, air pressure through sensors that have been placed and programmed to detect weather conditions around the monitoring location. This tool is designed to be able to monitor and manage data from anywhere in the area where this tool is placed as long as there is an internet connection. To add flexibility, the sensor data processed on the ESP32 microcontroller will be connected to an access point on the 2.4 GHz wireless network, then the data will be sent to the web server and will be displayed on the website. The focus of making this weather prediction tool is that it is hoped that with this weather prediction tool, factory owners can be assisted in the process of drying the grain, so that the dried grain can be peeled off and can be processed using a grinding machine to be sold to consumers in the form of rice.

Abstract

Wedding Organizer itself is one of the special services that helps the bride, their families in planning and supervising the implementation of the entire events of the wedding plan according to a predetermined schedule from the wedding ceremony, traditional ceremonies, aisles, etc. Such as the Imagine Wedding Organizer which is one of the cases in this study. In Imagine Wedding Organizer, the system used is still manual. Therefore, in this final report the author provides suggestions in the form of ordering web-based computerized Wedding Event Services. Where the system design uses Unifeld Modeling Language (UML) with the Hypertext Preprocessor (PHP) programming language, MYSQL database, and uses the Waterfall system development method and uses a system testing method called the BlackBox Testing Method. The result of this research is the establishment of a WEB-based Wedding Event Service Ordering Information System on Imagine Organizer. With the establishment of this system is expected to make it easier for customers to place orders.

Abstract

Warung Mbak Sih is engaged in the culinary field that serves home cooking such as mixed rice, spicy chicken rice, soup rice, sour rice, fried chicken rice, rawon rice. Lots of customers who buy on the spot or order to be packaged. With the application of ordering food at online stalls, the number of visitors queuing can be limited so that they are not too many. The preparation of the application has been done well by using the HTML and PHP programming languages, as well as the Bootstrap framework. The database used with XAMPP software to manage sata is in the form of the SQL framework Bootstrap language so that it displays good display results both in desktop form and in the form of mobile phone pages. With the ordering application, the time used by buyers at the shop is faster, because orders have been prepared in advance. In addition to ordering the application also displays a variety of good information for stall sales.
