Abstrak. Perkembangan internet yang cepat telah mengubah cara kehumasan berhub-ungan dengan masyarakat. Hal ini diikuti oleh fenomena dunia yang tanpa batas dimana tidak ada batasan bagi pengguna untuk memberikan respon terhadap suatu produk atau layanan yang berdampak pada kepercayaan yang telah dibangun selama bertahun-tahun oleh perusahaan dan publiknya. Petisi tentang IndiHome pada situs change.org mengindikasikan bahwa pelanggan me-rasa kecewa dan tidak lagi percaya pada Telkom. Penelitian ini menggunakan metode deskriptif kuantitatif dan kuesioner sebagai instrumen yang diberikan pada pelanggan dan pendukung petisi IndiHome pada situs change.org. Berdasarkan temuan dan analisis data, tingkat kepercayaan pelanggan pada Telkom jika dikaitkan dengan integritas dapat diketahui berada pada tingkat se-dang. Sekalipun demikian salah satu indikator integritas, yakni kejujuran memiliki penilaian negatif paling tinggi bila dibandingkan dengan indikator pemenuhan informasi maupun kehanda-lan. Data yang diperoleh dianalisis menggunakan tabel distribusi frekuensi dan kemudian dibagi ke dalam tiga kategori. Hasil penelitian menunjukkan bahwa dimensi integritas berada pada level moderat. Abtract. The rapid development of the internet changes the way of public relations get con-nected with their public. It also followed by “borderless” world which means limitless on users to argue about a product or service that may result in damage to the trust that has been established for many years by the company and their publics. Petition about IndiHome on Change.org means if customers feel disappointed and can’t longer believe Telkom. This study used quantitative de-scriptive research with questionnaire as a research instrument and distributed to consumers and supporter of petition about IndiHome on Change.org. Based on the findings and data analysis, the level of customers' trust on Telkom in relation to integrity is at a moderate level. Yet, one of the indicators of integrity, that is honesty, has the highest negative rating compared to information fulfillment and reliability indicators. The data was analyzed using table of distribution of frequen-cy and then recoded into three categories. The findings suggest that the dimension of integrity is at moderate level.

A number of social issues have been grown due to the increasing amount of “fake news”. With the inevitable exposure to this misinformation, it has become a real challenge for the public to process the correct truth and knowledge with accuracy. In this paper, we have applied machine learning to investigate the correlations between the information and the way people treat it. With enough data, we are able to safely and accurately predict which groups are most vulnerable to misinformation. In addition, we realized that the structure of the survey itself could help with future studies, and the method by which the news articles are presented, and the news articles itself also contributes to the result.

Background and Objective. To mitigate the spread of the virus responsible for COVID-19, known as SARS-CoV-2, there is an urgent need for massive population testing. Due to the constant shortage of PCR (polymerase chain reaction) test reagents, which are the tests for COVID-19 by excellence, several medical centers have opted for immunological tests to look for the presence of antibodies produced against this virus. However, these tests have a high rate of false positives (positive but actually negative test results) and false negatives (negative but actually positive test results) and are therefore not always reliable. In this paper, we proposed a solution based on Data Analysis and Machine Learning to detect COVID-19 infections. Methods. Our analysis and machine learning algorithm is based on most cited two clinical datasets from the literature: one from San Raffaele Hospital Milan Italia and the other from Hospital Israelita Albert Einstein São Paulo Brasilia. The datasets were processed to select the best features that most influence the target, and it turned out that almost all of them are blood parameters. EDA (Exploratory Data Analysis) methods were applied to the datasets, and a comparative study of supervised machine learning models was done, after which the support vector machine (SVM) was selected as the one with the best performance. Results. SVM being the best performant is used as our proposed supervised machine learning algorithm. An accuracy of 99.29%, sensitivity of 92.79%, and specificity of 100% were obtained with the dataset from Kaggle (https://www.kaggle.com/einsteindata4u/covid19) after applying optimization to SVM. The same procedure and work were performed with the dataset taken from San Raffaele Hospital (https://zenodo.org/record/3886927#.YIluB5AzbMV). Once more, the SVM presented the best performance among other machine learning algorithms, and 92.86%, 93.55%, and 90.91% for accuracy, sensitivity, and specificity, respectively, were obtained. Conclusion. The obtained results, when compared with others from the literature based on these same datasets, are superior, leading us to conclude that our proposed solution is reliable for the COVID-19 diagnosis.

With the progress of society and the rapid development of computer technology, rumors arise on social media, which seriously affects the social economy. How to detect rumors accurately and rapidly has become one hot research topic. In this paper, a new early rumor detection model is proposed. The aim of this model is to increase the efficiency and the accuracy of rumor detection simultaneously. Specifically, in this model, the input data is firstly refined through account filtering and data standardization, then the BiGRU is used to consider the context relationship, and a reinforcement learning algorithm is applied to detection. Experimental results show that compared with other early rumor detection models (e.g., checkpoints), the accuracy of the proposed model is improved by 0.5% with the same speed, which testifies the effectiveness of this model.

The periodical occurrence of emergency situations represents an important issue for mankind. Over the years, the world at large has experienced multiple misadventures both natural and man-made. A recent report showed that flood have affected more individuals than any other category of disaster in the 21st century with the highest percentage of 43% of all disaster events in 2019 and Africa been the second vulnerable continent after Asia. Handling flood risk with the intention of safety and comfort of the citizens as well as saving their environment is one of the major responsibilities of the leadership in each country especially in flood prone areas. Machine learning predictive analytic applications can improve the risk management. So, it is highly important to devise a scientific method for flood risk reduction since it cannot be eradicated. The paper proposes a pluvial flood detection and prediction system based on machine learning techniques. The proposed model will employ a fuzzy rule-based classification to appraise the performance of the machine learning algorithm on pluvial flood conditioning variables.
