Abstract

Cow's milk is a popular food and beverage consumed by the public. The benefits generated from cow's milk are numerous, because they contain protein, vitamins, and minerals needed in the body. Sales of cow's milk are often found in rural, urban, tourist attractions, roadside, to restaurants. Because there are so many people who need cow's milk, there are often bad sellers or sellers selling impure cow's milk. Because by falsifying cow's milk, naughty sellers benefit very much. From the falsification of the purity of cow's milk, there are a lot of losses felt by consumers, including consumers being a loss, so that the worse is consumers can be hospitalized because falsified milk is included ingredients that are not suitable for food. Therefore, to help the public not to get caught buying cow's milk which has been mixed with water by an individual, tools are needed that are able to test the purity of cow's milk directly and quickly. Because of this problem, a research was carried out to build a tool that could detect cow's milk, mixed milk or pure milk. This research requires a TCS3200 color sensor which is used to detect color in cow's milk, and also a pH sensor to obtain the acidity value in cow's milk. For the classification results using the Naive Bayes method calculation. The choice of using the Naive Bayes classification is because the method can be used to process biased data and accurate calculation results. Based on the test results, obtained an accuracy of Naive Bayes calculation of 90% taken from 20 times the test, and the test there are 2 results that are not appropriate. While the speed of calculating the device starts from the taking of the value by the sensor until the tool can issue an average classification result of 6932 ms.

Abstract

People in this digital era take a picture before eating is one of lifestyle. Then the result of the picture will be uploaded to social media. Traditional food's pictures dissemination still less identified encourages this research about the classification of traditional food's image. Extraction of classification features food image is difficult because of food can vary dramatically in appearances such as shape, texture, color, and other visual properties. Convolution Neural Network (CNN) is a method that can learn its own features on a complex image. Hopefully, CNN evaluation results for the classification image of traditional food can provide a solution to identify the image of traditional food. Result of this research in building the architecture of the Convolutional Neural Network model for classification of the traditional food image required 4 conditional layers, 4 max-pooling layers, and 2 fully connected layers. That architecture obtained because it gets the smallest loss value with 0.000044 value on the 15 epoch during the learning process and gets a 73% precision, 69% recall, and 69% F-score.

Abstract

Forest fires is a disaster that often occurs in various countries in the world, especially those with many forest areas. In June 2017, Portugal hit by a forest fire with a loss of more than 565 million US Dollars. In this case, meteorological data can affect several fire indices and can be used area forecasting for extra protection to prevent excessive losses and preservation of natural resources. This paper uses the backpropagation method, which begins with the calculation of preprocessing data (min max normalization, and logarithmic normalization). The weight normalization calculation use Nguyen Widrow method, the calculation of the feed forward process to determine the output at each iteration index, the error value is calculated at the iteration index and the weight is corrected using the backpropagation process. Furthermore, the output value is normalized to return the data to the initial range. The test results are calculated using Mean Square Error (MSE) on each parameter test. Test parameters get the best learning rate value that is 0.1 with the results of MSE 6743,716, 3 hidden neurons with MSE 6745,456, 10 epoch with MSE results 6740,684, and the 10% ratio of test 90% ratio of training data which produces MSE 1881,604.

Abstract

The capital city relocation policy of the Republic of Indonesia that was announced by President Joko Widodo last August caused many pros and cons in the community, especially in the social media environment. In this study, sentiment analysis of the policy is done using data obtained from Twitter. The system development process includes data scraping, preprocessing, Raw Term Frequency calculation and classification using the Naive Bayes method. In preprocessing, the filtering process is done using the Term-Based Random Sampling algorithm to create a stoplist. The testing process is done by 2 methods, parameter testing and multiclass confusion matrix testing. Parameter testing is done by changing the percentage of term of the training data used as a stoplist, ranging from 0 percent to 60 percent, while the confusion matrix is ​​used to calculate the value of accuracy, precision, recall, and f-measure. Based on the confusion matrix test results, the system gets the best macroaverage value in the classification with a stoplist of 20 percent with an accuracy macroaverage value of 0,94, precision macroaverage value of 0,945, recall macroaverage value of 0,94, and f-measure macroaverage value of 0,938.

Abstract

MANET nodes are dynamic, which means that nodes can freely join and leave the network so that the formation of network topologies is dynamic. Each node can also behave abnormally like a black hole attack that can interfere with the routing process. Black hole attacks work by stating that they have the shortest route to the destination node to the source node. This will be very dangerous if the package sent is a package that contains important information so MANET needs a security mechanism to be able to detect and avoid black hole attacks. The detection system for black hole attacks consists of the process of searching for black holes and avoiding black hole routes. black hole search process is done by sending a RREQ message with a fake destination address. If there is a reply from the fake RREQ message, the RREP message sending node is marked as a black hole. The results of testing with a detection mechanism can find out the location of a black hole, it is proven by a mechanism that can overcome black holes in the scenario of the position of different black holes. In the test results can be seen when there is a black hole detection mechanism, the PDR value in the random walk movement of 94.164% can be greater than 0.00410408% without a detection mechanism. This happens because the data sent from the source node can reach more destination nodes than without the detection mechanism
