Abstract

Forecasting systems with fuzzy time series capturing the pattern of past data and then use it to project future data. The process also does not require a complex learning system as it exists on genetic algorithms and neural networks, so that make the system is easy to develop. In the prediction using fuzzy time series, the length of the interval has been determined at the beginning of the calculation process. While determining the interval length is very influential in the formation of fuzzy relationships also will have an impact on the prediction of the outcome differences. Therefore, the formation of the fuzzy relationship must be precise and it requires the determination of an appropriate interval length. One method that can be used to determine the effective length of the interval is an average based method.

Abstract

Lake is an important land feature for human life. Changes in a lake's condition would affect the environment and the people living nearby. One of the method being used to detect changes in lake's condition is by using an edge detection of the lake based on satellite image for further analysis such as measuring the change in lake's total area. Appropriate implementation and optimization of such algorithm can lead to a better analysis of the lake's condition. In this research, the system implemented Canny Edge Detection algorithm to detect the edge of a lake on a satellite image. A segmentation algorithm based on color thresholding is used to improve the edge detection algorithm. The test result shows that Canny Edge Detection algorithm has 57% error detection rate, while segmentation process using color thresholding improves the detection performance by 67%.

Abstract

The number of culinary attractions in Malang that can be reached makes it difficult for culinary lovers to find the optimum route, in terms of distance, time, and cost to travel from one place to another. One of the factor that influence people's when they did culinary tour is the transportation fees. A thing that is very relate with transportation is the distance. Many culinary lovers feel like they have wasting their time to get to the place they want because they choose the wrong routes. Since Malang has so many culinary attractions, it takes optimization in searching the optimum route from starting point to the destination point. The bee colony algorithm was chosen because the algorithm is considered to have the ability to exit local minimum and can be efficiently used for optimization. Bee colony algorithm also can solve the problem of Traveling Salesman Problem better than other algorithm which is also based on group intelligence. At the experiment we can conclude that bee colony algorithm has converged in the search for the best solution that can be seen from the fitness resulted. One of the best have been convergence in bee colony at 20 of 50 bee colony amounts. In addition the convergence can also be seen on the number of iterations at 20 of the maximum number of iterations 50.

Abstract

Climate change that happens because of global warming also cause change in rainfall patterns. Knowing rainfall patterns is really important for some activity and works. So, rainfall forecasting is needed to understand the rainfall patterns in the future. One of the method used in forecasting is Support Vector Regression. But, SVR still has weakness in determining the right values for the parameters. So, an optimization algortithm is needed to help determining the values of the parameters in SVR. The purpose of this research is to do rainfall forecasting in Pujon area, Malang using Support Vector Regression that's been optimized by Improved-Particle Swarm Optimization. Optimization of SVR is done for getting the optimal values of SVR's parameters. The optimized SVR's parameters are (learning rate constants), (complexity), (Hessian's coefficient), (error rate) dan (kernel's coefficient). The rainfall forecasting for the first ten days of January from 2007 until 2015 by using IPSO-SVR resulted value of 0.213389 in RMSE compared to using only SVR which resulted value of 25.839085 in RMSE. This proved that optimization of SVR using IPSO is better compared to using the unoptimized SVR.

Abstract

Schizophrenia is a severe mental disorder that contains thoughts, language, perceptions, and self-awareness. There are several types of schizophrenia. The relationship between the type of schizophrenia and its symptoms has uncertainty, where a symptom A is not necessarily only result in schizophrenia type X, but can lead to schizophrenia type Y. In rural areas, mental health facilities are still inadequate, so that the people there treat patients with schizophrenia with unnatural as at the brackets even in stocks. Actually, people with schizophrenia can be handled with the provision of drugs and psychological therapy with regular. Based on these problems, the authors create expert systems that are able to find solutions as do an expert in diagnosing and providing treatment solutions in patients with schizophrenia. Thus, general practitioners in small community clinics or hospitals in small areas can diagnose patients suffering from the schizophrenia. This expert system uses Bayesian Network method, PHP programming language and MySQL database. Experimental functional test results show all functional requirements can run well. In addition, the highest accuracy test results in testing the variation of training data is 92.86%. With the results of such accuracy, this expert system has a good performance to make the diagnosis of schizophrenia disease

Abstract

Soil is a crusial component for plant growth. There are many parameters that used for soil examination, and one of its parameter is soil's dampness. Soil Laboratory Balai Pengkajian Teknologi Pertanian Jawa Timur is one of the work units that has a duty to examine the soil for plant nursery purpose. However, due to the conventional tools that they used sometimes the examination result is not as accurate as they expected. Because of that problem the author did some research to make a smart computing system that can be implemented on a tool that can maintain the soil's dampness automatically. Fuzzy Inference System Mamdani is used to calculate how long does it take to water the plants by using two variable inputs; initial dampness and water volume. Genetic algorithm is used to get an optimal membership function by optimizing the boundaries of each membership function. The output of this research will display the optimal time to water the plants. From the examination result we got an error value for about 2,516651, but after optimization the number is reduced to 0,000121. With that result we can conclude that using Fuzzy Inference System Mamdani and optimized with genetic algorithm is able to calculate how much time that it takes to water the plants and still able to get a good outcome. Keywords: Plants, fuzzy inference system, Mamdani, genetic algorithm, optimization
