<![CDATA[Based on a survey conducted by the Top Brand Award in the courier service category, the J&T Express company is in the highest position from 2018 to 2021 beating Pos Indonesia. Social media Twitter is a place often used by customers to submit complaints and opinions regarding the services of a company. The method used to determine the tendency of the views to contain positive or negative sentiments is sentiment analysis. Sentiment analysis will classify the polarity of the text in sentences or documents to determine whether the opinions expressed are positive or negative. This study uses the Support Vector Machine (SVM) algorithm. The results of the user tweet data used are as many as 1000 data with details of data 206 (20.6%) have positive sentiments and 794 (79.4%) have negative sentiments. In the Pos Indonesia tweet data, 110 positive sentiment data were obtained, while the positive sentiment data in the J&T Express tweet data was 96 data. This shows that the Pos Indonesia delivery service has better customer service than J&T Express. The highest level of accuracy using the SVM algorithm in classifying sentiment is 80.14% with a comparison of 70% training data and 30% test data with an average precision of 90%, an average recall of 51.74%, and an average f-measure of 47.80%.]]>

<![CDATA[Augmented Reality (AR), is a technology that uses the concept of combining real reality with virtual reality in real time. Augmented Reality is not the same as virtual reality capable of replacing real-world reality, but it is useful for adding or supplementing. With a 3-dimensional object inserted in the target object marker which is a special image or pattern which has been inserted by 3D image, it can be detected by the application and display a 3-dimensional image in real-time. Android smartphones can allow for AR development that can be accessed by many users and it is very easy to use. AR can be used to display products in 3 dimensions on websites of e-commerce. Augmented Reality can be used to make it easier for buyers to interact directly with products in a real way in the virtual world. The method used to design the CV.Sukses Group website was to use the MDLC (Multimedia Development Life Cycle) method which consisted of concept, design, material collecting, assembly, testing, and distribution. The results of this research were in the form of e-commerce websites, AR applications, and 3-dimensional objects. The purpose of this final project was to develop an Augmented Reality application aimed at buyers who wanted to interact directly with CV.Sukses Group products. This application was created with Unity and Vuforia Engine as AR application development tools. For websites built using a WordPress CMS. The application of Augmented Reality-based technology on the CV.Sukses Group e-commerce website could read markers on product images that would display 3-dimensional models on the screen of android devices in real-time.]]>

<![CDATA[The government implements learning with a new paradigm called the independent curriculum. The government gives flexibility to schools to choose three implementation paths, namely Independent Learning, Independent Change and Independent Sharing. However, schools have difficulties in determining the appropriate model. This study aims to help schools decide on the most ideal independent curriculum implementation model to be implemented in schools. The research method uses TOPSIS, which is a decision support method that can help solve multi-criteria problems by providing results that are closest to the ideal. The results of the study show that respondents chose the Independent Changing path for the implementation of an independent curriculum in educational units by considering the readiness of educational units, the availability of information technology and the teacher's desire to change]]>

<![CDATA[Lack of knowledge and information about diseases in pregnancy can delay pregnant women from knowing there are diseases in their pregnancy. Diseases that attack a woman's womb need to be examined by an expert, while experts for this disease are still rare and require a lot of money. In order for the initial diagnosis to be carried out by pregnant women, a solution is proposed in the form of an expert system for diagnosing pregnant women's diseases using the Certainty Factor (CF) method based on the symptoms felt by pregnant women. The research stages used in this study used 4 steps, namely data collection consisting of disease data and symptom data, disease data and symptoms, as well as patient data, symptoms and weights, data analysis using the certainty factor method, validation and evaluation. Diagnostic results that are not in accordance with the CF calculation of around 37.5%, while the results in accordance with the CF calculation were 11 patients or 62.5%.]]>

<![CDATA[Start-ups are important pillars in improving people's lives, and many start-ups will certainly increase employment. Still, it must understand that start-ups should be limited to the business. Many start-ups have closed down due to a need for integrated management, human resources, capital, and so on; these require proper guidance to reach the highest level. This article complements the previous article, namely the Development of Mentoring Management in Producing High-Quality Human Resources at the University Level in Facing the ASEAN Economic Community (MEA) Using the Kiyosaki Concept Blanchard ABCD Trust Methods-HSOVA. This guidance is essential to maintain, improve and develop existing start-ups. With the accuracy of guidance, it is necessary so start-ups to turn on profit and develop human resources in communication, psychology, and more targeted life goals. This article's result is a profiling mentoring framework; in this framework, there will be guiding people who want to work in the start-up field. Furthermore, the maturity level of mentoring profiling is one part of this framework. This framework will be flexible, applied, and adapted to existing conditions during a pandemic.]]>

<![CDATA[This article discusses strategies to achieve good data governance in Indonesia amidst data security challenges, including data security cases that have occurred in Indonesia. According to the IT Governance Institute (ITGI) in 2021, only 34% of companies in Indonesia have implemented good data governance standards. This indicates a gap in understanding between organizations, as they have not fully realized and understood the importance of data governance. This study used a narrative review as a methodology to evaluate relevant studies related to this topic. The findings show the importance of sustainable data governance and cybersecurity, but only a small portion of organizations in Indonesia have implemented data governance strategies or data intelligence solutions. This article highlights strategies to improve data security in data governance in Indonesia through a better understanding of information security practices. The Data Management Association (DAMA) International Guide to the Data Management Body of Knowledge (DMBOK) concept is used as a conceptual framework for this research. This article provides significant information on strategies to improve security practices in data governance and the safe use of data, which can improve economic well-being.]]>
