Abstract

The number of open unemployment in Indonesia has increased and decreased every year. The factors that can make unemployment happens is the number of the labor force is not balanced to the available jobs. In addition, the weakening of labor absorption in some industrial sectors has also the cause of the increasing number of open unemployment in Indonesia. Predict the number of open unemployment, expected can help the government and related parties to take the appropriate policy to reduce the number of open unemployment in Indonesia. Genetic-based backpropagation is one of the methods that can be implemented to perform predictions. This method performs weight and biases optimization process as parameters in backpropagation training. In this research the result value of Average Forecast Error Rate (AFER) of backpropagation method is 4.715198444% and genetic-based backpropagation method is 3.877514478%. Based on the result value of AFER, genetic-based backpropagation method can be used to predict the number of open unemployment in Indonesia with a better accuracy.

Abstract

One of the major problems that Indonesia has is unemployment. It happens because of the low number of the job vacancy meets the high number of the graduate and job seeker. The unbalanced number of the job vacancy to the graduate and job seeker causes an increasing in the unemployment rate in Indonesia. The high rate of unemployment will inevitably give a direct or indirect impact to the poverty, crime, and other social issues. However, according to the survey conducted by BPS, Indonesia's unemployment rate was even increasing from the year of 2014 to 2015. It would really help the Indonesian government to make planning, program, or policy related to the job vacancy by being able to predict the number of unemployment. In addition, the data result from the prediction could be used as the measurement of the success of government's previous programs. Backpropagation is one of the methods that used to predict. This research works on the optimation of weights initialization in Backpropagation using Bayesian method that is a modification of the Kalman filter. According to the test result done in this research, the lowest value of Average Forecasting Error Rate (AFER) is 2,1003%. From that result, the combination method between Backpropagation and Bayesian has better accuracy rate than Backpropagation method with random initialization that has 2,5793% lowest value of AFER, but need a lot of iterasion. The sistem of this research can predict some future of years immediately but the most optimal result is the first year while in subsequent years the result of the prediction is more inaccurate.

Abstract

Autism is a neurological disorder that shows significant result as a lack of ability to form social relationships, normal communication, and behavior in children. This symptoms generally appear before children reach the age of 3 years. It is not classified as a psychiatric disease because autism is a disorder that occurs malfunction of children's brain and it is manifested on children's behaviour. Some research states that autism causes as the neurodevelopmental disorder that causes abnormalities in children's brain structure. Different experts mentioned that autism in children caused by the kind of food they consumed or they living environment that contain many harmful substances that shows in children's behaviour. Therefore, the system for the identification of autism disorders in children will be create to help identifies autism disorder by using the method of Modified K-Nearest Neighbor (MKNN). It is one of classification method based on the appearance of largest classes in data training. There are 14 symptoms from 4 aspects that are used as parameters in the development of the system. The output of the system is showing whether a child is autistic individuals or not. Based on the testing that has been done on the system that using Modified K-Nearest Neighbor (MKNN), maximum accuracy shows 100% accuracy while minimum accuracy is 92%. Based on those results, the uses of Modified K-Nearest Neighbor (MKNN) method can be implemented in our daily life.

Abstract

The rapid development of mobile application encourages the creation of many applications with a variety of uses to fulfill user needs. Each application allows users to post a review about the application. The aim of the review is to evaluate and improve the quality of future products. For that purpose, analysis sentiment can be used to classify the review into positive or negative sentiment. Application reviews usually have spelling errors which makes them difficult to understand. The word that have spelling error needs to be normalized so it can be transformed into standard word. Hence, words normalization is needed to solve spelling error problem. This research used word normalization based on Levenshtein distance. Based on testing, the highest accuracy is found in ratio of 70% training data and 30% testing data. The highest accuracy of this research using edit value <=2 is 100%, the second highest of edit value is obtained at edit value <=1 with accuracy of 96,4%, while edit value with the lowest accuracy is obtained at edit value <=4 and <=5 with accuracy of 66,6%. The result of using Naive Bayes-Levenshtein Distance has accuracy value of 96,9% compared to Naive Bayes without the Levenshtein Distance with accuracy value of 94,4%.

Abstract

Beef is a commodity whose demand level is always high because it is a livestock product that has nutritional value to obtain protein requirement for society. Increase in beef demand in Indonesia has not been matched by beef production, in terms of both quality and quantity. Beef demand is influenced by beef production, beef consumption, and income levels. In anticipation of the increasing demand for beef, it is necessary to forecast to estimate future demand for beef. To make the forecasting there are various methods used, one of them is the method of multifactors high order fuzzy time series model. The method is a method of forecasting that uses antecedent factor and more than one order, which is considered better than using only one antecedent factor (Lin & Yang, 2009). This research obtained the average forecasting error rate (AFER) of 6.648381805287571% which shows that the smaller error value means the level of accuracy.

Abstract

Stock is a proof of investing in a corporation and stock holders have the right to claim part of corporation's earning and assets. Stock holders can gain a lot ot of benefit such receiving dividens and selling their stocks with higher value (capital gain). Stock holders need to be careful to manage their assets because stock prices keep changing over time. Stock holders usually monitor stock prices change and analyze them by forecasting. Support Vector Regression (SVR) is one of forecasting methods that performs well in both linear and non linear data. SVR can obtained a fitted model that is neither overfit nor underfit. However SVR has one drawback. The performance of SVR is greatly affected by its parameter. So finding the right parameter value on SVR is needed to gain a good forecasting result. One of optimization algorithms is Genetic Algorithm. Genetic Algorithm is used in order to get the right value of SVR parameter. SVR that is optimized by Genetic Algorithm is capable of getting a good result in forecasting. The test shows error rate/MAPE of forecasting is 0.165% which is smaller than using SVR which is 1.612% with best parameters such as population size 50, generation 200, crossover rate 0.4, mutation rate 0.6, range of sigma 0.5-1, range of epsilon 10-7-10-3, range of C 0.001-5, and range of gamma 10-5-10-3.

Abstract

Milk has a complete nutrition that important for body so every people can consume milk with high quality. Determination of milk quality can by tools called Milkoscope Julie c2 or Lactoscan to test the chemical contents. That tools can identified the chemical content which includes 7 parameters. From 7 parameters, 3 parameters are provisions of SNI and 4 parameters are not listed in porvisions of SNI. If we determine milk quality only from 3 parameter in SNI, the result is not the best. Based on that problems, we need a system that can help us to determine quality of milk considering 7 parameters. Method that can be used for this problem is Learning Vector Quantization (LVQ) but LVQ need an optimazion method to produce the best weight vector and increase accuracy using Genethic Algorithm (GA). Best weight vector of GA will be used for LVQ training and the latest wight vector of training used for testing. The result of this research obtained the highest accuracy average is 88% with best parameters such as population size 30, crossover rate 0,5, mutation rate 0,5, generation 75, alpha 0,6, and alpha decrement 0,3.
