Main issues that occured in Sangkalami River is there was an active open pit coal mine nearby and currently using Sangkalami River as the main outlet of Acid Mine Drainage as a result of mining activities. The goal of this research is to be able provide information regarding potential contamination in Sangkalami River due to coal mine activities nearby. Sample water from the river will be taken to be tested in laboratory for extracting information regarding existing water quality. Government Regulation of Indonesia Number 22 of 2021 will be used as water quality standard to compare the level of pH, Mn, H2S, DO, COD, and BOD in Sangkalami River to the government implemented standard regarding water quality. Main goal of the study is to be able to provide information about contamination level that occured in Sangkalami River.

They can be also used by business entities to find out public opinion about their product or the performance of their business products. It will be very difficult to process the review data manually and it will take a long time. Therefore, sentiment analysis automation can be used to get polarity information from existing reviews. In this study, IndoBERT with Recurrent Convolutional Neural Network (RCNN) was used to automate sentiment analysis of Indonesian reviews. The data used was a sentiment analysis dataset obtained from IndoNLU with sentiment consisting of negative sentiment, neutral sentiment, and positive sentiment. The results of the test showed that IndoBERT with the Recurrent Convolutional Neural Network (RCNN) had better results than the IndoBERT base. IndoBERT with Recurrent Convolutional Neural...

Thus, detecting and correcting errors automatically in writing answers is necessary. The implementation of Levenshtein Distance and N-Gram can detect writing errors. However, this process needed a long time because of the distance method used. Therefore, this research aims to hybrid Jaro Winker and N-Gram methods to detect and correct writing errors automatically. This process required preprocessing and finding the best word recommendations by the Jaro Winkler method, which refers to Kamus Besar Bahasa Indonesia (KBBI). The N-Gram method refers to the corpus. The final scoring used the Vector Space Model (VSM) method based on the similarity of words between the answer keys and the respondent’s answers. Datasets used 115 answers from 23 respondents with some writing errors. The results of Jaro Winkler and N-Gram methods are good in detecting and correcting Indonesian words with the accuracy of detection averages of 83.64% (minimum of 57....

Which will help OTA Services to understand about customer satisfaction and customer loyalty so that they can develop their business in the future in order to get greater customer satisfaction and loyalty.Design/methodology/approach: Using the American Customer Satisfaction Index (ACSI) Model which explains the antecedents and consequences of customer satisfaction. In Antecedent there are variables of User Expectations, Perceived Quality, and Value benefits that have an impact on customer satisfaction variables then from causing customer complaints and customer loyalty. So that 9 research hypotheses are obtained based on the model used and tested using Structural Equation Modeling (SEM). Research requires data on respondents' answers distributed through digital media with a total need for 385 respondent data.Findings/result: After testing using SEM.The 9 hypotheses proposed show that 2 hypothese...

Clear, correct and precise information is indispensable to provide insight into this respiratory virus. Digital media is widely used by the public to find links about the covid19 virus. Health topics about covid 19 from several sites will be collected by scrapping method, and the data retrieval results will be processed to become an automatic summary using Latent Semantic Analysis (LSA), where this method, will help to find the hidden meaning of a collection of sentences. The formation of the summary is assisted by the cross method. The system also has an article search to allow users to find the right information. The results of this study showed that LSA method assisted by the cross method could be used in automatic summary shrinking well, test results in f-measure and recall values on average of 90....

Hal ini dikarenakan, dari segi jumlah bendera negara yang begitu banyak di dunia sesuai dengan banyaknya jumlah negara yang ada di dunia, apalagi dari segi warna, bendera negara memiliki kombinasi warna yang hampir mirip satu sama lain untuk tiap-tiap negara. Penelitian ini bertujuan untuk membuat rancang bangun sebuah aplikasi pengenalan bendera negara menggunakan histogram yang diharapkan sistem dapat membantu mempermudah user dalam mengenali bendera dari tiap negara di dunia tanpa harus menghafal atau mengingat, bahkan bagi user yang sama sekali belum mengetahuinya. Aplikasi yang dibangun ini mampu mengenali gambar bendera negara dalam bentuk format file image bitmap (*.bmp). Pengenalan pola bendera ini dilakukan dengan menggunakan nilai kesalahan atau nilai SSE (Sum Square Error) sebagai faktor penentu, sehingga menghasilkan nama negara yang sesuai den...

We hypothesize that managing synonyms with a good taxonomy and a good integration process are good approaches to organize and share knowledge. This paper can give a discourse to a group of people in different societies that want to share data using different concepts in the same domain. We will generate a common set of terms based on the terms of several different storage devices, used by different societies, in order to make data retrieval independent of the different perceptions and terminologies used by those societies. We use ontologies to represent the particular knowledge of each society and integration techniques to find relations between terms used in those ontologies. Keywords—Ontology; Knowledge; Synonyms; Taxonomy

These applications are used to fulfill a set of tasks such as semantic indexing, knowledge extraction from text, information retrieval, etc. Using these resources and combining them for the same application is a tedious task with different levels of complexity. This requires their representation in a common language, extracting the required knowledge and designing effective large scale storage structures offering operators for resources management. For instance, ontology repositories were created to address these issues by collecting heterogeneous ontologies. They generally offer a more effective indexing of these resources than general search engines by generating alignments and annotations to ensure their interoperability. However, these repositories treat a single category of resources and do not provide operations for reusing them. The aim of this research is building a large repository of...
