<![CDATA[Online news is a source of information for people; this impacts journalists as news writers who can find news information quickly and accurately every day. Journalists can plagiarise other journalists or take news material from other news media sites and use it to publish in the media without including the source. An algorithm is needed to measure the similarity of online news. This work proposed the Jaro Winkler algorithm, with the value obtained from the calculation normalised so that the value 0 means there is no resemblance, and one means it has the exact resemblance. The data used is 20 online news media sites in the Central Kalimantan area. The Scraping process utilised the Custome Search JSON API and used keywords to get the news on the same topic. The results of the calculation of news similarity with the Jaro Winkler algorithm obtained an average value of online news similarity of 74.49%, with 43 news data with severe plagiarism levels and 12 news data with moderate plagiarism levels. There are weaknesses in the Jaro Winkler algorithm in calculating the similarity value in the data obtained. Some undetected data should have a heavy plagiarism level but not severe and vice versa.]]>

<![CDATA[Cosmetics are products that are often used to beautify one's appearance. CV. Cahaya Sejati, which is one of the providers of cosmetics in Asahan Regency. The cosmetics that were targeted in this study were lipstick, solid powder, shampoo, liquid soap, perfume and handbody with different brands. The results of observations and interviews with the owner of the CV. Cahaya Sejati, cosmetic stock data collection in the warehouse still uses manual recording, so it takes a long time to see the cosmetic stock. In addition, the stock of cosmetics sold for sale so far has sometimes increased with different categories of cosmetics, some increasing and some decreasing. The instability of cosmetic sales makes the owner of CV. Cahaya Sejati has difficulty in determining the amount of cosmetic stock that will be sold in the future. The purpose of this study is to apply the Single Exponential Smoothing method to predict cosmetics in the future. The research method uses the Single Exponential Smoothing method. The stages of the method are cosmetic data collection, data analysis begins with determining the alpha value and calculating the single exponential smoothing method and performing the error accuracy process with MAD, MSE and MAPE. By using the Single Exponential Smoothing method, it will be carried out to predict the stock of cosmetics in the following month, namely March 2022 by using data from March to February 2022. So that the owner of CV. Cahaya Sejati will be able to make a decision in providing cosmetics in the following month. The results showed that in March 2022, Handbody: HBL Liora produced 18.02 with MAPE 22.45%, Lipstick: Dolby produced 22.57 with MAPE 19.36%, Liquid Soap: SPA. Gell yielded 23.10 with a MAPE of 19.27%, Shampoo : Doll yielded 17.26 with a MAPE of 29.25%, and Compact Powder : TWC Dolby yielded 24.74 with a MAPE of 19.91%. So it can be concluded that by applying the single exponential smoothing method, it can be used as a reference for making cosmetic stock decisions at CV. True Light.]]>

<![CDATA[Sistem Informasi Akademik (SIMAK) of Siliwangi University is one of the information systems developed by UPT TIK, Siliwangi University. SIMAK must be able to become a website that is easy to use, has informative value, and has a high level of usability. User experience in using and operating it can be a measure of acceptance of SIMAK. Based on previous research, it is stated that SIMAK still does not meet the expectations of users. Therefore, in this study usability evaluation was carried out based on the Heuristic Evaluation and Web Usability Evaluation (WEBUSE) approaches. This study discusses the results of usability analysis based on the results of data collection from questionnaires distributed to 100 respondents who are active students (S1), lecturers, and staff at Siliwangi University. The results of usability measurements based on the Heuristic Evaluation method obtained usability points of 70.74% and the results of usability measurements based on the WEBUSE method obtained usability points of 67.84%. The results of usability measurements based on the Heuristic Evaluation and WEBUSE methods have consistent results which state that the SIMAK UNSIL website has a usability level of "Good". However, in some variable indicators there are still indicators that have low values, therefore it is necessary to make improvements based on the recommendations given to improve SIMAK quality.]]>

<![CDATA[One of the government's efforts in equitable distribution of education is to launch the PAUD Regional Operational Assistance (BOSDA) program by providing financial assistance for each PAUD with underprivileged students. This Regional Operational Assistance (BOSDA) aims to reduce the cost of education for underprivileged children, so that they can obtain early childhood education services that can optimally foster, grow, and develop the full potential of early childhood. The problem that occurs is the Determination of Regional Operational Assistance Recipients (BOSDA) which is not optimal and not right on target. The purpose of this research is to facilitate the UPT employees of the Education Office in determining the recipients of the Regional Operational Assistance (BOSDA) program with the right decision results. Therefore, the UPT Department of Education requires the right technology to assist employees in determining the recipients of PAUD Regional Operational Assistance (BOSDA). In achieving the research objectives, the analysis used is data analysis with quantitative methods which is a data analysis used if the conclusions obtained can be proven by numbers and also in the calculation of formulas that have to do with research analysis. The calculation process uses the WP method, so that the results of the assessment that have been carried out go through many calculation processes, ranging from weighting the values of all criteria and determining the value to getting a candidate for PAUD Regional Operational Assistance (BOSDA) at the UPT of the Buntu Pane District Education Office.]]>

<![CDATA[Music has become an important part of human life, chorus is part of the musical structure that makes some impression on music, people are generally very familiar with the chorus in music because the chorus is often repeated on music. Automatic chorus detection is a part of Music Information Retrieval which is considered important for building music analysis system with human-like patterns. Refrain Detecting Method (RefraiD) select the chorus by grouping various repeating parts of the music, evaluating the intensity level of the melody from each group, then selecting the group with the highest melodic intensity as the chorus. This paper intends to implement RefraiD in Indonesian pop and dangdut music by downloading 20 pop music videos and 20 dangdut music videos from YouTube then process it with Information retrieval using Python. The results of this paper indicate that the RefraiD method can be used to detect the chorus on Indonesian music with F measure of 91.8% for dangdut music and 91.5% for pop music.]]>
