Abstract

Developing technology has had an impact in many ways such as watching a movie, in the past watching a movie had to be through television or cinema media. This resulted in difficulties due to inefficient broadcast schedules, as well as the inability to replay. But unlike the current era, watching movies can be done anywhere and anytime by utilizing a streaming application. One of the existing applications is Netflix, in this application there are many types of movies from all walks of life, not only that the monthly subscription system in this application is relatively cheap. The existing streaming applications are not only Netflix but there are still many other applications, therefore Netflix needs to pay attention to the reviews given by users so that this application continues to grow and is not defeated by other applications. Reviews given by users can be used as evaluation material, to see reviews cannot be seen at a glance but must be detailed. Because there are quite a lot of reviews that manual processes cannot be applied, it is necessary to use a sentiment analysis process and utilize existing algorithms such as data mining. This study aims to conduct sentiment analysis based on user reviews of the Netflix application on the google playstore. The review data of 1,000 was taken by the author and then obtained the results of the research that the reviews given by users tended to be negative and the naïve bayes algorithm got an accuracy level of 82%.

Abstract

At Universitas Amikom Purwokerto, the Institute for Research and Community Service (LPPM) faces significant challenges in financial data processing. Currently, financial data is managed using Microsoft Excel, and there is no system in place to properly manage and store this data. This lack of an efficient system hinders effective financial management and data handling. To address these issues, the proposed solution is to develop a website for financial management that supports the tri dharma of higher education. Effective web application development necessitates adherence to standard front-end framework models. Therefore, this study focuses on creating a front-end for the LPPM financial website using Bootstrap, following the waterfall method due to its sequential, structured, and reliable properties. The result of this study is a website-based LPPM financial application front-end. Based on test results, the front-end of this website achieved an SUS (System Usability Scale) score of 80.5, which falls into grade B. This indicates that the application is expected to facilitate the process of managing financial data and enhance user interaction with the system, effectively resolving the identified issues. This research was successful because it had created a front-end system in accordance with the needs that had been complained about by the university.

Abstract

Since the advent of modern communication and information technologies, the field of education and learning has seen profound transformations. Websites that can access different kinds of data online are one example of this. Some schools still haven't figured out how to make the most of the internet, despite the fact that it has revolutionized many parts of life, including education. Colleges and universities must adapt to the changing times by implementing new methods of learning that raise the bar for student achievement. Unfortunately, many teachers still rely on the ineffective lecture format, which results for dull and unengaging classroom discussions. Hence, new approaches to education are required. Learning using the TGT (Team Games Tournament) concept is something to think about. By combining aspects of teamwork and competition, this approach creates engaging and motivating games that promote the application of learning principles. Technology, particularly websites, plays an important role in implementing the TGT paradigm in learning. Applications that facilitate the use of the TGT learning paradigm are the focus of this study. We used the waterfall approach for this study. This allows for the implementation of innovative learning strategies, which in turn boost student engagement and the quality of their learning. By using information technology, this TGT model-based application aims to improve the learning process and address the drawbacks of conventional learning approaches.

Abstract

Stunting remains a critical public health challenge in Indonesia, primarily due to inadequate nutrition and recurrent infections in early childhood. This study aimed to identify patterns of stunting risk by integrating anthropometric and dietary data, specifically sugar consumption, using an unsupervised machine learning approach. A total of 20 toddlers aged 12-59 months from Purwokerto Selatan participated. Anthropometric data (age, weight, height) and dietary intake (sugar consumption, snack frequency) were collected via a caregiver questionnaire. K-Means clustering was applied, with the optimal number of clusters determined using the Elbow Method (K=2). Two clusters were identified: Cluster 0, with a lower risk of stunting, and Cluster 1, with a higher proportion of toddlers at risk. Cross-tabulation with stunting status validated this, showing that Cluster 1 contained more children with "Potential" stunting. Internal validation using the Silhouette score (0.252) and PCA visualization confirmed the clustering's robustness. This study demonstrates the potential of combining anthropometric and dietary data for stunting risk profiling, suggesting a complementary approach for growth monitoring programs and targeted interventions.
