Abstract

Sentiment analysis is a field that is currently in great demand by various groups. Sentiment analysis can be done using documents and opinions from social media. One social media that is usually used as a means of opinion is Facebook social media. Before a text is classified, it is necessary to do POS Tagging which is the word labeling stage where the purpose is to determine the words which include opinions and non opinions. For labeling words can use the Hidden Markov Model or Rule Based. The method commonly used in sentiment analysis is the Naïve Bayes Classifier method. This method simply classifies probabilities. Naïve Bayes Classifier can be used to classify opinions into positive and negative opinions. In addition, this method uses training data in the classification process. The classification produced from the Naïve Bayes Classifier method is quite good. To test the accuracy of the system in classifying opinions, the classification results are tested. From the test results obtained an average accuracy of 87.1%. The more training data that is similar to testing data, the better the classification results.

Abstract

In fulfilling current electrical energy needs, a power plant unit is operated using various fuels. The biggest cost of the total operating costs of the plant is the cost of using the generator unit fuel which is around 60%, therefore a solution is needed to be able to minimize the costs of using generator fuel in operating the generating unit. Economic Dispatch is a way to overcome the economic operating problem of a power plant by dividing the load on each operating unit so that the minimum generation cost is obtained. The solution to the Economic Dispatch problem can be done using the Fuzzy Logic Controller (FLC) method because the FLC method can make very complex decisions and in its application does not require mathematical models that are too difficult to solve, so the FLC method is expected to minimize the cost of generating electricity. The results of calculating the Economic Dispatch using the FLC method result in a lower total production cost compared to the total total production costs of the System and the Lamda Iteration method for 24 hours on September 30, 2017.

Abstract

Indonesia has a lot of energy potential, both conventional (Non Renewable) and Renewable Energy. Energy potential that is mostly used for the Indonesian region still uses conventional energy (Non Renewable) in the form of fossil fuels (coal, natural gas and petroleum). At present, fossil energy use reaches 75% and will continue to increase. To avoid the use of fossil energy, studies are carried out on renewable energy (Non Renewable) for example Micro Hydro. The working principle of the Micro Hydro Power Plant use the potential energy of water which is converted into electrical energy. In this final project research has been made modeling of micro hydro power plants using screw turbines (Archimedean Screw) with tubrine blade angle variations ranging from 240, 260,280,300 and 320. The measurements made in this study include measurement of turbine rotation, generator rotation, voltage, current and torque generated in the modeling that has been made. From the measurements that have been made using a lamp load of 25 Watts the highest measurement results are obtained at an angle of 280. At an angle of 280 produces a power of 10.8 Watts, torque of 0.33 Nm and efficiency of 11.6%.
