PT XYZ Tbk is the largest transportation rental service company in Indonesia. However, the process of submitting a lease from a customer still takes a long time and a lot of resources because it is done manually. It's very important for an organization to facilitate the business process with digitalization and to change physical files and documents to digital files (paperless) in the form of e-documents accompanied by e-digital signatures so that the process becomes faster, more effective and efficient. Therefore, this research purpose is to propose an E-Rent vehicle rental system to digitalize the current business processes. To determine the proposed design, research was conducted by analyzing user requirements, system requirements and conducting design modeling using the Object Oriented Analysis and Design method. Based on the result of the research conducted, it is expected the proposed system can meet the needs of the users in the vehicle rental process., both the users in the company and the customers.

The planning for the development of Information Systems and Technology is carried out with the main goal of realizing the Vision and Mission of Higher Education. The Information System design framework used is TOGAF (The Open Group Architecture Framework) - ADM (Architecture Development Methode), in that framework consists of several steps of implementing a representative architectural design to be used in architectural design at the Toyota Indonesia Community Academy which focuses on Business, Data, Applications and Technology. For the information system security management system, TOGAF-ADM can collaborate with ISO 27001:2013, where when we plan the development of the enterprise information system architecture for universities, we must also focus on information system security in accordance with the information system security system contained in the ISO 27001 :2013. By using a combination framework between TOGAF-ADM and ISO 27001, it is very appropriate to be used as a method for planning Enterprise Architecture in Higher Education that prioritizes business, applications and technology and adopts an information security management system from ISO 27001.

In higher education, the completion of a thesis within a 1-year timeframe is a prerequisite for graduation. The selection of a thesis topic is influenced by personal interest, the expertise of the thesis supervisor, and data availability. This research is designed to analyze the thesis topics of Economics Faculty students at Garut University using the Latent Dirichlet Allocation (LDA) Modeling method. Utilizing quantitative and qualitative approaches, this research applies the concept of big data with techniques such as Data Crawling, Data Preprocessing, and Text Mining. The research successfully conducted topic modeling using the LDA method. The analysis showed that topic modeling with the LDA algorithm resulted in seven common thesis topics used in the students' thesis titles. With this, the research contributes to the understanding and efficacy in the determination of students' thesis topics. It is hoped that the results of this research can be utilized to assist in the efficient completion of theses.Â Keywords: Topic Analysis; Topic Modeling; Thesis Title; Latent Dirichlet Allocation; LDA

Hospitality is one area that has the potentia l to implement information systems because hospitality is a business that prioritizes satisfaction, in this case, namely service. A good business stra tegy is needed to support the business. Ta lking about business stra tegy will not be separated from the so-called strategy of information systems and information technology. Therefore, a mature information system strategic planning can be used as a reference to ga in a competitive advantage for Villa Buleud Garut. The purpose of this study is to ana lyze environmental factors to determine the strengths, weaknesses, opportunities and threats that are owned and to identify the critical success factors so that a proposed information system strategy plan can be developed in the form of an application development portfolio at the future Villa Buleud. In this study the authors made direct observations at Villa Buleud, conducted interviews, and gave questionnaires to related parties and read literature. In compiling the framework in this study the authors used the Wa rd and Peppa rd approach. Which of these approaches is to carry out an analysis of the Internal Business Environment, Externa l Business Environment, Interna l IS/IT Environment, and Externa l IS/IT Environment using severa l ana lytica l methods, namely Va lue Chain ana lysis, PEST Analysis, Five Force Porter, McFarlan Strategic Grid, SWOT Ana lysis, Critical Success Factor, and Ba lanced Scoreca rd. The fina l result of this resea rch is the proposed formulation of the future IS/IT stra tegy for Villa Buleud Ga rut which includes changes to the vision and mission of Villa Buleud, changes to organizationa l structure, information system application requirements, network architecture, future business processes, and future Villa Buleud application portfolio.

SatuSehat is a contact tracing application that replaces the PeduliLindungi application initiated by the Government of Indonesia with the aim of tracking the Covid -19 Virus. The success of the application can be known by analyzing sentiment reviews. In addition to the high number of reviews, there are also other things that need to be highlighted, namely the pattern of reviews that are not in accordance with refined spelling and diverse topics, so that identifying a topic from a collection of reviews is very difficult and takes a lot of time if done manually by humans. This research describes sentiment analysis and topic modeling on SatuSehat app user reviews. By applying Support Vector Machine (SVM) method for sentiment analysis and Latent Dirichlet Allocation (LDA) for topic modeling, this study reveals the views and trends expressed by users. The analyzed review data from Google Play Store includes 171,428 positive reviews and 131,246 negative reviews. The sentiment analysis results indicated the dominance of positive responses. LDA modeling resulted in 8 identified topics, from health concerns to app appreciation. However, negative topics included vaccination challenges, access issues, and app functionality. This research provides insight into users' perceptions of the SatuSehat app, providing a basis for further development and improvement of the app.

In the current era, technological advancements in Indonesia have created extensive resources for information and communication for the community also equal with basic human needs such as clothing and food. SMKN 2 GARUT is a favorite school in Garut city, with a focus on academic and non-academic achievements. Despite the school utilizing technology such as a website, the alumni data management system, including tracer studies, is still conducted manually. This research for develop a website-based tracer study information system for SMKN 2 GARUT. Currently, alumni data is collected through the filling of biodata forms, which are then submitted to the Counseling guidance for consolidation and management. After verification, the data is sent to Headmaster. However, the system still relies on manual processes with the use of poorly managed gform links. This leads to delays in information delivery, ease of data duplication, and human error risks. In this research, the researcher employs the prototype development method, which includes requirement analysis, prototype design, system implementation, program coding, and testing. The tracer study system is developed using PHP 7.0 programming language with CodeIgniter framework and MySQL database. Based on the conducted development analysis, this application improves the average time efficiency compared to the previous system. Additionally, the use of this application reduces costs in generating alumni data reports and facilitates alumni data management at SMKN 2 GARUT. This tracer study information system effectively manages alumni data, provides appropriate control, and can be accessed through internet technology.
