<![CDATA[Taking photos while traveling is certainly familiar today. Sharing the photos taken is also one of the mandatory parts to do, whether traveling alone, as a family, or in a group. Taking and sharing these photos is used for memories and even life satisfaction. In general, the activity of sharing photos that are captured using social media such as WhatsApp, LINE, Instagram, or others. The process of sharing photos on social media has limitations, where the photos that are shared must download first because there is no preview of the photos. This download process will use storage on the user's device. This is certainly not efficient if the photos sent are not in accordance with user context. The development of this photo sharing application uses the SDLC method starting from the analysis process to testing. This application provides a system where users can view photos shared by other users without download. This application will also backup photos on Firebase Storage as well as Google Photos. Image Labeling technology from Google ML Kit also helps to extract the information contained in the image and the extraction results will be used as a hashtag on the photo and can be used to search images using hashtags. The test was carried out on 10 testers and the application can help in sharing photos and there is no need to download to be able to view the shared photos. In addition, the use of image labeling from the Google ML Kit library is also very helpful in performing image searches.]]>

<![CDATA[The implementation of a self-service system is already used by many libraries, mainly on self-loan books. Self-service generally only uses RFID as a medium for identifying members and borrowed books, but using RFID alone as the head of the identification process may lead to many crimes such as using someone else's member card to borrow books, scam, and so on. This study aims to propose a new business process for self loan books from the library by combining NFC or RFID technology and 2FA (two-factor authentication) to minimize the crimes such as fraudulence, scams, and so on. The results showed that the system or prototype could work and function properly. The process of reading NFC tags and the use of 2F also runs quickly and safely.]]>

<![CDATA[Satya Wacana Christian University (UKSW) is one of the private higher education institutions in Indonesia that utilizes the internet network, namely the web as a medium for conveying information, connecting the academic community and others. UKSW has many webs that are used, one of which is the SIASAT web. SIASAT is Satya Wacana Academic Information System. SIASAT contains important information about the community. Web SIASAT provides information in a private manner or only those with an account can view the information. However, not only people who have access can access the information, but other irresponsible parties can access it in the wrong way and misuse the existing information. So that it can cause harm to the person or organization. SIASAT often experiences security problems with SQL Injection, brute force, and so on but there has never been a hacker who can penetrate the SIASAT web, therefore the SIASAT web needs to be tested for security. Factors that need to be considered in determining security are confidentiality is maintaining the confidentiality of information from unauthorized people, integrity maintaining changes in information from unauthorized people, and availability keeping information accessible. Therefore, in overcoming this problem, one of the steps that can be taken is to analyze the UKSW web where the web to be analyzed is the SIASAT web with the Open Web Application Security Project (OWASP) method. The hope is that with the OWASP, the handling of an attack can be carried out earlier and prevent fatal consequences.]]>

<![CDATA[The Covid-19 outbreak that spread rapidly around the world including in Indonesia, has affected various fields, one of which is education. The government’s policy concerning PSBB forced the schools to change th learning process into online learning. However, there are factors to consider in its application, one of which is student acceptance of the learning method. This study was conducted with the participation of 437 Indonesian high school students in Indonesia. The analysis was conducted using the Structural Equation Modeling (SEM) method, with the Unified Theory of Acceptance and Use of Technology (UTAUT) acceptance model serving as the theoretical framework and being supplemented by three new exogenous variables. The findings suggest that the additional variable Perceived Enjoyment is the most influential factor on the acceptance of online learning systems among Indonesian high school students during the COVID-19 pandemic. In addition, of the four original exogenous variables in UTAUT, only Effort Expectancy and Facilitating Condition play a significant role in increasing students' intention to continue adopting online learning systems. The findings from this study can serve as a guide for secondary school online learning policies, even after the pandemic has ended.]]>

<![CDATA[Academic Information System is a very important system in assisting the academic process in Higher Education. Jenderal Sudirman University has long implemented an Academic Information System to serve the academic activities of the academic community. The Academic Information System must be evaluated or tested in order to ensure the quality of the system which will affect the performance of the system. Software quality testing is carried out using the ISO 9126 standard method to identify software quality attributes with reference to five quality measures, namely functionality, reliability, usability, efficiency, and portability, and also tested using the Mean Opinion Score (MOS) method which is a method for measuring the performance and quality of applications built from the user's perspective, as well as testing website performance using GTMetrix. The results of testing the ISO 9126 method show "very good" quality which is reinforced by the results of the Mean Opinion Score (MOS) method testing with an average score of 97.33% and the results of the GTMetrix test getting a score of C (pretty good) with a Performance value of 70% and Structure value of 87%.]]>

<![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[The Warcam store is a store that sells various frozen food products since 2019. The sales process at this Warcam store often experiences a shortage or excess stock of frozen food which causes losses for shop owners. This happens because Warcam Stores have not know how to calculate inventory. This study will discuss how the stages of making a forecasting system using the website-based trend moment method can help to predict frozen food stocks. The data used is data from 2019 to 2020 with in 360 transactions. The stages begin with business understanding, data understanding, and data preparation. Build a model using flowchart and perform a simulation of product forecasting calculations until an evaluation. This system was created using the PHP programming language and MySQL database with the CRISP-DM (Cross Industry Standard Process For Data Mining) approach. From the results of testing the system that has been made, this system can predict frozen food stocks with an error value of 14.52%. This error states that the forecast is still not correct, there are still excess and or lack of stock so that further research needs to be carried out using other methods.]]>
