Abstract

The purpose of this study is to determine the prediction of rice farming yields in Padangsidimpuan City through SVM (Support Vector Machine) Algorithms. This type of research used quantitative methods of SVM (Support Vector Machine) with a Data-Driven development (DDD) method. This approach utilized patterns and trends in data to build accurate prediction models where the DDD method can be used when researchers have access to relevant and meaningful data to guide the development of software or prediction models.The SVM algorithm has proven to be effective in predicting rice yield trends, both in determining the direction of change (up or down) and in estimating the value of the next harvest. The implemented SVM model is able to identify patterns of change in historical data and provide relevant predictions for agricultural yields. Historical data covering a fairly long period of time provides sufficient information for models to identify trends and patterns. This model can provide better predictions with more complete and high-quality data.

Abstract

Demonstrating attentive behavior when users decide to share information on social media is vital. Such attentiveness helps users more effectively identify misinformation, allowing them to avoid being misled by hidden deceptive content. The rapid increase of information in online media today means that the dissemination of misinformation can have serious negative consequences, such as threatening political stability and democracy, which can lead to societal divisions. While many studies have investigated the traceability and prediction of misinformation spread, additional research is necessary to understand and prevent the disruptions in human attention that contribute to this issue. This leads to questions about how technological interventions can enhance user awareness during the decision-making process of sharing information, especially to promote honest and constructive communication in a democratic context. The objective of this research is to examine and intervene in the factors of user attention when sharing information online, particularly regarding communication and democratic participation in Indonesia. This study employs a mixed-methods design, combining both quantitative and qualitative approaches. It is structured into two phases: Study 1 involves an investigation into the importance of attention factors in social media sharing through a self-report survey with adult participants from Palembang. Additionally, in Study 2, we designed and tested a Visual Selective Attention System (VSAS) using a Sociotechnical Design approach to influence decision-making by implementing an attention-focused design. We hope that the future development of interactions within a VSAS-based social media application will yield sustainable insights that encourage a non-coercive approach to managing the sharing of misinformation, thereby supporting transparent and fair communication and democratic participation (LUBER and JURDIL) in Indonesia.

Abstract

This research aims to design a web-based online thesis guidance application for the Computer Science program to facilitate the processing of student thesis data and enhance the thesis guidance process for better completion of final thesis tasks. In the thesis guidance process of the Computer Science program, several obstacles hinder students' progress in completing their theses. These obstacles include the need for students to bring their thesis materials in physical form during conventional guidance processes. This can lead to additional issues, such as the cost of printing thesis materials for corrections by supervising professors. This research utilizes the PHP programming language with the assistance of the CodeIgniter framework and MySQL as the database. The System Development Life Cycle (SDLC) Waterfall method was employed for the software development phase of this research. This method was chosen because it is a simple and linear classic model, where the output of each stage becomes the input for the next stage. Data collection techniques in this research included observation, interviews, and literature studies. This research results in a web-based online thesis guidance application that provides convenience for both students and supervising professors in conducting thesis guidance. This application also assists the Computer Science program and its students taking thesis courses. The application is more efficient when conducted online, minimizing wasted paper printouts and saving time during the guidance period, ensuring that the thesis report can be completed promptly.
