Abstract

Microservice architecture as a solution to the monolithic architectural system is growing more and more in use today. As a fairly successful solution, the microservice system is not devoid of new problems and other challenges that arise. Microservice as a self-developed system and a service that communicates between networks are often fault. Any fault that occurs can be caused by high latency or because of the internal problem that causes the slowing down process. This may cause microservice to be inaccessible to the user or other microservice in need. The research provides a solution to the implementation of a microservice system that can withstand fault by applying the stability pattern with a circuit breaker and bulkhead pattern. Tests are made on the implementation of microservice systems using the PRS case study used by the Christian university of Petra. Fault executives are implemented to test the comparative performance of a DFTM method of circuit breaker with a circuit breaker, a bulkhead with no bulkhead, and to measure the fault levels microservice by MRMM. Based on the results of the tests, DFTM circuit breaker performance was at 46% faster than normal. The results of the testing also have the subtractable use of bulkhead could prevent resource use more than the capacity of microservice servers had if the latency was higher. Testing result also mentioned that the fault tolerance of the microservice measured by MRMM violating resilience of the benchmark. This can be proven from declining success rates, increased average response time, and decreased transactions per second.

Abstract

Apologetika Indonesia  are religious organizations that support the defense of Christian faith that supports the truth related to Christianity. The method used in the discussion of apologetic content is by holding seminars and lectures in churches throughout Indonesia. Supposedly, with the existing technology, the spread of content can be done easily through the internet, namely through the apps. The media used must also be resilient to bad internet conditions because the spread of content wants to reach places that might have poor internet conditions. But the Apologetika Indoesia also does not have a website to run the online course.The author makes a website and conducts research on performance measurement between standard websites and websites that have a Progressive Web App. The results show that websites with progressive web applications have a worse performance than ordinary sites. However, in testing Progressive Web App , websites that use Progressive Web App can respond better, especially at points that can respond offline. In situations of poor internet connection, it cannot be denied that websites that use Progressive Web Applications can respond much better than ordinary websites.

Abstract

The computer center at Petra Christian University has not been able to measure the utilization of laptop space, so it cannot know the number of users who are using laptop space facilities. Despite the existence of a registration system in using these facilities, the number of student registration lists with the number of users who use the laptop room is not appropriate because there are students who do not register first. For this reason, the system for calculating the number of users uses background subtraction using the MOG2 and GMG methods so that it can help find out the number of people who use laptop room facilities.In this study will create a program to count the number of users by detecting people, and create a website program system to display data on the number of users. This system was created using C ++, and a website was created using PHP and MySQL databasesThe results of this study indicate that the lighting factor and frame resolution are very influential on the accuracy of the user's detection. The effect of detection lighting can be seen from the results of the confusion matrix which shows that what is detected mostly exceeds the number of users in the room. While the effect of resolution on detection can be seen from the results of F1 scores on one of the lighting videos that showed using a resolution of 1280x720 the results of the MOG2 method reached 68% and the GMG method reached 40%. After reducing the frame to 640x360, the average value of MOG2 reaches 86% and the GMG method reaches 67%.
