Abstract

The increase in population and growth in the farming field was one of the reason of rising in consumption of animal protein. One of the source of animal protein that has been the most preferable for its affordable price and easy to get, is purebred chicken egg. However, the issue in purebred chicken egg sales that has been faced by the market is its fluctuate price. Therefore, the researcher build a forecasting system using Particle Swarm Optimization-Neural Network (PSO-NN). This method proved to be better than the NN training using Backpropagation. PSO training will be carried out to the maximum iteration and the results of the training in the form of optimal weight values will be used as initialization weights for NN training. The type of NN used is Feedforward Neural Network (FFNN). The NN training is done by using 4 lag time, 2 hidden units, and 1 output which represents the result of price forecasting. Based on the result of this research, PSO proved to be able to speed up NN on finding the optimal solution. The lowest MAPE found using PSO-NN in this research is 1.01552%.

Abstract

Malaria is a disease transmitted by female Anopheles mosquitoes infected by a parasite (protozoa) originating from the genus Plasmodium. There are four species of protozoa parasites that commonly attack humans, including: Plasmodium vivax which causes malaria tertiana, Plasmodium falciparum causes malaria tropica, Plasmodium malariae causes malaria quartana, and Plasmodium ovale causes malaria ovale. These four malaria cases almost have the same symptoms, so it is not easy to distinguish between one to another. Therefore, a system that can classify these types of malaria based on the symptoms is needed. Classification is the creation of a model that is used to classify an object into a predetermined class based on the same characteristics. One of the classification method is Support Vector Machine (SVM). Therefore the SVMs classification algorithm using the RBF kernel is being used in this study. The data used were 200 data taken from Dinas Kesehatan Kabupaten Nabire, Papua. In this test used K-fold Cross Validation with the K-fold values = 10. The best accuracy results generated by this system is 72.5% with the value of the parameter λ=0.1, σ=1, γ=0.001, C=0.1, ε=1.10-5, itermax=50 data on the ratio of 80% training data : 20% testing data.

Abstract

Generally, testing consist of 3 phase,specifically generate test case, execute test case, and evaluate the testing result. Software testing is a process that expend a lot in both time and resources. One way to reduce the time and resources is by automate the test case generation. Test case can be derived from use case scenario. This kind of test case is called black-box test case. Use case scenario has many different formats, this paper will use the Cockburn format. In order to transform the use case scenario. This research use natural language processing and EFSM (Extended Finite State Machine) model. Natural language processing will be used for generating activity table. The activity table will modeled with EFSM and tranversed to produce a test case. This research will develop the tool using java that allows the tools to run on platform that supports JRE (Java Runtime Environment). The tools is tested using unit testing, integration testing, and validation testing. Unit and integration will be conducted with whitebox method, while validation testing is done using black-box method. The tool can generate test case from 20 use case scenario in less than 120 seconds.
