Abstract

Cyberbullying is one of the actions that violate the ITE Law where the crime is committed on social media applications such as Twitter. This action is difficult to detect if no one is reporting the tweet. Cyberbullying tweet identification aims to classify tweets that contain bullying. Classification is done using Support Vector Machine method where this method aims to find the dividing hyperplane between negative and positive class. This study is a text classification where more data is used, the more features are produced, therefore this research also uses Information Gain as feature selection to select features that are not relevant to the classification. The process of the system starts from text preprocessing with tokenizing, filtering, stemming and term weighting. Then perform the information gain feature selection by calculating the entropy value of each term. After that perform the classification process based on the terms that have been selected, and the output of the system is identification whether the tweet is bullying or not. The result of using SVM method is accuracy 75%, precision 70.27%, recall 86.66% and f-measure 77.61% on experiment iterMax value = 20, λ = 0.5, γ = 0.001, ε = 0.000001, and C = 1.

Abstract

Fire is a disaster that often occurs in the community but there are still many lay people who do not know how to use and the types of fire extinguishers or APAR. According to interviews with the head of the Technical Implementation Unit of Fire Brigade, in the training and the introduction of the Fire Fighter Department and Regional Disaster Management Agency (BPBD) there are shortcomings such as the number of APAR that amounts to a little, so employees can not try. APAR training also has an accident risk. Therefore, case studies in this study are the general public who do not understand about the type of APAR and its usefulness. Based on the problems described, this research will design and build a simulation and game using Virtual Reality technology. By utilizing this technology the user is not required to deal with real fire. This simulation can minimize accidents during APAR training and save the use of APAR. This simulation can visualize events so that the user can still feel how to extinguish the fire and the use of light extinguishers or APAR. With this simulation users will be better prepared when the fire occurred in the environment. Then for testing the usability of the implementation in building the Simulation and Fire Extinguisher game is obtained satisfactory results with an average above the standard that is 80.

Abstract

Obesity occurs due to buildup of fat in the body is very high. Thus causing weight gain be not ideal. Obesity can also cause disease complications, some of which can endanger lives. To get the ideal body weight and the minimum cost incurred, the patient needs to control the amount of food intake is by regulating the composition of food that enters the body. The research was done by optimizing food composition for obese people in adults using Particle Swarm Optimization Algorithm (PSO). In this study, the initial particle formation of the particle random based on the amount of food so there is no need to convert that into food index. The results displayed by the program is actual body weight, ideal weight, nutritional status, energy needs, the needs of protein, fat and carbohydrate needs needs. While the test results obtained the optimal parameters such as the number of particles = 80, the number of iterations based on testing convergence of 703, = 0,4, = 0,7 c1i = 1,5 and c1f = 0,3, c2i = 0,3 and c2f = 1,5. The results of the program with the first patient parameters produce an average difference between the actual data with the data from the program registration -2,08% and it can reduce the cost of expenditure up to 6,85%. While the second patient the average of the actual data difference with data from the program amounted to -1,06% and it can reduce the cost of expenditure up to 5,93%.
