Abstract

Scheduling is an important issue in the implementation of activities, so that absence of such activities will not run smoothly. One example of scheduling is the scheduling of semester exam is performed on a STMIK Kadiri. Scheduling tests done still manually (conventional) so it may take longer computation. This is because the difficulty of putting slots schedule to avoid clashing occurs and there are lots of class but the test room which can be used a bit. So it needs optimization scheduling that is able to minimize conflicting schedules and activities the test can run well. Genetic algorithm is one of the most common optimization methods is used to solve the problems of scheduling. The data used in this study using the test schedule data will be represented in chromosomes, in the form of code exam schedule. Crossover method used is onecut point while mutase method using reciporal exchange mutation and elitism selection method and roulette wheel. The optimal parameter values ​​obtained based on the test result are population size 60, generation size as much as 850, with cr and mr value is 0,5 and 0,5. So the fitness value that is gained is 0.000574..

Abstract

The factor of fish quality can be affected by storage procedure and processing treatment is still done manually. Of course, it can make the fish quality will decrease and the sorting process will be wrong. From this problem, it is needed some research and system that can reduce errors to classify fish quality. On this research, we are using image processing and Bayesian method to classify fish quality. Fish will be placed on a styrofoam box that has been equipped with a webcam camera and lamp as lighting. Image processing is used to convert an image from RGB space to HSV space, and we crop the image to get the head section. And after that, we use the hue histogram colour information for the parameter to classify. so the value of bin1, bin 2, and bin 3 and also the standard deviation from histogram value are using as input for classification using Naive Bayes and will process in Raspberry Pi 3 and finally, we can get the fish quality. We are doing some testing. From testing how to implement image processing for this system we get some conclusion that the image which uses the lighting from 5 Watt lamp with white fabric clothes has a good image result, and the result for hue value information from images has to be added. And from testing Naive Bayes methods accuracy was 72.727% and the computation time was 468.864 ms.

Abstract

Wireless mesh network is a network consisting of several devices that are connected to each other to send and receive data, and act as a relay for sending data on a small network scope. Because video streaming process in a network requires connection between the server and the client that runs continuously and real time, so the codec used, the size of the video, and the location of the server and client affect the quality of video streaming results. Recommended standards for video streaming to run smoothly is that the jitter value is no more or equal to 10 ms to 50 ms, and packet loss is not more than 0.5%. In this study, testing of video streaming is carried out on a wireless mesh network based on Babel routing protocol with a limited number of devices using H.264 and MJPEG codecs. The quality of network service in each test scenario is determined in the form of delay, throughput, jitter, and packet loss, then the test results between H.264 and MJPEG codecs are compared. After testing, H.264 codec has packet loss value of 2.14% while the MJPEG codec has packet loss value of 5.03%. H.264 codec has a jitter value of 164154.38 ms while the MJPEG codec has a jitter value of 305.67 ms. H.264 codec has a throughput value of 0.016 MB/s while MJPEG codec has a throughput value of 0.047 MB/s. H.264 codec has a delay value of 0.036 ms while the MJPEG codec has a delay value of 0.0306 ms. Jitter and packet loss value from testing using the H.264 codec do not meet the recommended standard values for video streaming.
