Abstract

Fuzzy clustering is a clustering method whcih allows an object to belong to two or more cluster by combining hard-clustering and fuzzy membership matrix. Two popular algorithms used in fuzzy clustering are Fuzzy C-Means (FCM) and Gustafson Kessel (GK). The FCM use Euclideans distance for determining cluster membership, while GK use Fuzzy Covariance Matrix that considering covariance between variables. Although GK perform better, it has some drawbacks on handling linearly correlated data, and as FCM the algorithm produce unstable result due to random initialization. These drawbacks can be overcame by using improved covariance estimation and cluster ensemble, respectively. This research presents the implementation of improved covariance estimation and cluster ensemble on GK method and compare it with FCM-Ensemble.

Abstract

TransJakarta is one of the most common public transportation modes used by the public in Jakarta. Every day there are more than 300.000 people who use TransJakarta . The number of TransJakarta buses is still limited, so to optimize services, we should know when the number of users in peak time and when the number of users in low time. In addition to providing comfort to customers, maintenance for TransJakarta buses can also be optimized, thereby reducing incident and unwanted events. This study investigates the pattern of the number of TransJakarta passengers differs on weekends, weekdays, and holidays. Also, this study predict how many TransJakarta passengers in the future, by using SARIMAX method, which is SARIMA method with X - factor. In the implementation, the study is conducted using R application with the addition of x-factor in the form of dummy variable for tap-in data in holiday period.The predicted result being produced is not too far away with the actual figure with the best model is SARIMA(0,0,0)(2,1,0)[7] with x-factor and the error analys is MSE = 162402173, MAPE = 2.6122 and MASE = 0.211698.

Abstract

The large number of people who refuse to get vaccines is one of the biggest challenges for the Indonesian government in dealing with the COVID-19 pandemic. Widespread misinformation and hoaxes about COVID-19 vaccines has made the level of public trust decreases. This paper was written to see how the public's opinion on the side effects of the three COVID-19 vaccines that have been spreading in Indonesia, among them are Sinovac, Astra Zeneca and Moderna. There will be a sentiment analysis and grouping of public conversations on Twitter with LDA regarding the side effects of the three vaccines. From the results obtained, it is expected to be a reference for the government or related parties in order to validate the issues that circulated among the society regarding the side effects of the COVID-19 vaccine. From the results of the analysis, it was found that in the Sinovac vaccine type, people tend to state that the side effects felt are quite mild, dominated by the words sleepy, achy & hungry. While for the Astra Zeneca & Moderna vaccine, people tend to state that the side effects are quite severe, such as fever, pain, and dizziness. The results of the analysis also found that the Astra Zeneca vaccine was the type of vaccine that received the most negative opinions from the public.
