<![CDATA[The success or failure of a company depends on the human resources in the company. The quality of every human resource is needed to improve performance productivity. The process of appointing permanent employees is something that is often done by companies, one of the reasons is the company's appreciation of employee performance. For this reason, the process of appointing employees is more professional, so a decision support system is needed to assist in selecting employees who deserve to be appointed as permanent employees. The method will be applied in this research is simple additive weighting (SAW). SAW method is selected because it is very simple, can determine the value of weight then determine the ranking of the results of normalization. There are ten criteria and weights for each of the criteria used in this research. The purpose of this research is to design and create a web based information system as a tool for decision making in the process of appointment employees. It is hoped that this information system will benefit for the company so hat the employee appointment process do optimally and the time is more efficient.]]>

<![CDATA[Abstract - The quality of airline services can be seen from any opinions or reviews on passengers before. This reviewer classification grouped into positive opinion and a negative opinion. Data mining classification algorithm used is Naive Bayes are widely used in research because it serves well as a text classifier method however has the disadvantage that is very sensitive in the selection of features. Genetic Algorithm (GA) is one of the optimization algorithms, which is invented to mimic some of the processes observed in natural evolution. After testing the two models, namely models Naive Bayes algorithm and Naive Bayes algorithm based on the results obtained GA is Naive Bayes algorithm produces an accuracy of 60.00% while for Naive Bayes algorithm based on GA value amounted to 89.50% accuracy. Difference in value by 29.5% accuracy and included into the category of excellent classification. Keywords: Sentiment Analysis, Review, Naive Bayes, Text Classification Abstrak - Kualitas layanan maskapai dapat dilihat dari pendapat atau review penumpang sebelumnya. Klasifikasi resensi ini dikelompokkan menjadi opini positif dan pendapat negatif. algoritma klasifikasi data mining yang digunakan adalah Naive Bayes secara luas digunakan dalam penelitian karena berfungsi juga sebagai metode classifier teks namun memiliki kelemahan yang sangat sensitif dalam pemilihan fitur. Algoritma genetik (GA) merupakan salah satu algoritma optimasi, yang diciptakan untuk meniru beberapa proses yang diamati dalam evolusi alam. Setelah menguji dua model, yaitu model algoritma Naive Bayes dan algoritma Naive Bayes berdasarkan hasil yang diperoleh GA adalah algoritma Naive Bayes menghasilkan akurasi 60,00% sedangkan untuk algoritma Naive Bayes berdasarkan nilai GA sebesar akurasi 89,50%. Selisih nilai dengan akurasi 29,5% dan termasuk ke dalam kategori klasifikasi sangat baik.Kata Kunci: Analisis Sentimen, Ulasan, Naif Bayes, Klasifikasi Teks]]>

<![CDATA[The development of Information Technology makes increasing use of the internet. This raises the vulnerability of data security. Cyber attacks in Indonesia caused many tweets on social media Twitter. Some are positive, and some are negative. The problem of this study is to determine the public sentiment towards data security in Indonesia, while the purpose of this study is how the response or evaluation of the government of Indonesia to the many perceptions of people who lack confidence in data security in Indonesia. Data obtained from twitter with as much as 706 data was processed using python with a percentage of 10% test data and 90% training data. Weighting is done using TF-IDF, and then the Data is processed using the Support Vector Machine algorithm using the SVC (Support Vector Classification) library. Support Vector Classification with RBF kernel classifies Text well to obtain AUC value with good classification category. Utilizing one of the hyperparameter techniques, which is a grid search technique that can compare the accuracy of test results. The test results using SVC with RBF kernel obtained an accuracy value of 0.87, Precision of 0.82, recall of 0.94, and F1_Score of 0.87. This study is expected to be used by decision-makers related to public confidence in data security in Indonesia]]>

<![CDATA[The Ministry of Religious Affairs proposes to increase the cost of Hajj Travel (Bipih) in 1444 H/2023 M to Rp.69.19 million. There is a fairly high increase in costs compared to 2022. This raises sentiment in the community, there are public opinions for and against the issue of rising Bipih on social media twitter. The purpose of this study was to analyze the sentiment on the issue of increasing the cost of Hajj Travel and to prove whether Naive Bayes is a good classifier of text on the issue of incremental sentiment. Naive Baye is one of the best text classifier algorithms. Data taken from social media twitter. The Data are grouped into pro and Contra opinions and then processed using python programming language and jupyter as text editor. Data used as much as 850 data. The Data is divided into training data and testing data with a ratio of 80:20. With the number of training data of 679 data and the number of testing data of 170 data. Then implement Multinominal Naive Bayes algorithm (MNB) as text classifier and word weighting using TF-IDF. The test results obtained accuracy value of 89% and ROC value of 0.91. It is proven that Multinominal Naive Bayes algorithm (MNB) is a good classifier of text for sentiment analysis of opinion on the issue of increasing the cost of Hajj travel because it is included in the Excellent Classification.]]>
