Abstract

Mathematics is one of the important subjects. Mathematics is also a subject that is difficult to understand. Understanding concepts is the most important part of learning mathematics, meaning that in studying mathematics students must first understand mathematical concepts in order to be able to solve problems and be able to apply this learning in the real world. Based on direct observations and interviews with grade 6 teachers at SD Negeri 02 Getas, teachers have difficulties in the theme of lesson 3 about "Building Space" with basic competencies; 1) identify & compare geometric shapes; 2) calculating the surface area of the geometric shape; 3) calculate the volume of the geometric shape. This is what drives the need to develop game-based mathematics learning media. This game was created using Construct2 software as a 2D video game engine. The method used in this study is the MDLC (Multimedia Development Life Cycle) method. Mathematics is one of the important subjects. Mathematics is also a subject that is difficult to understand.

Abstract

This research develops an indoor air quality monitoring notification system for production rooms based on the Internet of Things (IoT) using the ESP8266. The system is designed to detect and provide early warnings of air pollution in production rooms. The Sharp GP2Y1010AU0F sensor is used to measure the concentration of dust particles in the air. Data from the sensor is sent to the ESP8266 module connected to the internet. This information is then forwarded to the Blynk application, enabling real-time monitoring through mobile devices. If the dust concentration exceeds the predetermined threshold, the system will activate the buzzer as an alarm. Test results show that this system can provide accurate and responsive notifications, thus helping to improve safety and health in the production environment.

Abstract

Fingerprint recognition is a popular biometric technology due to its unique properties and high accuracy rate. Fingerprint recognition systems generally use fingerprint image representations, such as grayscale images, phase images, skeleton images, and minutiae. In this research, fingerprint image pre-processing is performed using Gaussian Blur, Median Blur, Thresholding, Otsu Thresholding, Thinning with Guo-Hall algorithm, and Minutiae Detection. Minutiae detection produces 426 termination points and 459 bifurcation points. The results of the pre-processing and minutiae detection were then used for minutiae matching on 5 different images. Minutiae matching produces varying degrees of similarity with a high level of accuracy, reaching an average accuracy of 88.80%.

Abstract

This research aims to predict customer churn in a telecommunications company using Logistic Regression (LR) and Gradient Boosting Classifier (GBC) algorithms. Customer churn poses a significant challenge as acquiring new customers is costlier than retaining existing ones. The dataset from Kaggle comprises 7043 records and 21 attributes. The process includes data pre-processing, cleaning, transformation, and normalization using a Min-Max Scaler. The data is split into features (X) and target (y), then divided into training and testing sets with an 80:20 ratio. Both models were trained and evaluated using a confusion matrix. Results show that the GBC model outperforms the LR model, with an accuracy of 83% compared to LR's 81%. This study demonstrates the effectiveness of GBC in predicting customer churn.

Abstract

The advancement of e-commerce has changed the way people shop. However, there is a mismatch between the actual quality of a product and the seller’s description. Product reviews are an important source of information for making purchasing decisions. However, processing large numbers of reviews manually is difficult. This research aims to detect emotions in Indonesian language product review texts using contextual embeddings. The public dataset used was PRDECT-ID, which comprises five emotion labels. The methods used include data preprocessing, feature extraction using contextual embeddings such as Bidirectional Encoder Representations from Transformers (BERT), and classification using Decision Tree, Naïve Bayes, and k-Nearest Neighbors (KNN). Among the compared models, the KNN model demonstrated the highest improvement, achieving a 15.09% enhancement over the decision tree results. This research provides insights into the effectiveness of contextual embeddings in detecting emotions in Indonesian language product review texts.

Abstract

Android is an operating system whose capabilities continue to increase from year to year. The capabilities of Android currently match the capabilities of a computer. Not only limited to ordinary computers, what a server computer can do can now be done on Android, including making Android a web server. So it is possible for people who have Android to have their own web server. The problem that arises is that the web server on Android cannot be accessed directly via the internet. Cellular operators do not provide Public IP to their customers, so a way is needed so that the Android web server can be accessed on the internet, one of which is by using Virtual Private Network (VPN) technology. The aim of this research is to make the web server on Android accessible on the internet. The method used is to combine a Virtual Private Server (VPS) and Android using VPN. The research results showed that VPN can be a bridge so that the web server on Android can be accessed from the internet.

Abstract

The research examined interactive text as a possible interactive form of pictorial communication for generation z meaningfully engaging on online platforms. By adopting a three-phase methodology towards design, realización and evaluation, the research examines how much movement, responsiveness and user interactivity influences the interpretation of the the communicative message and the emotional. The research uses an interweaving of methodologies. Methodology usability testing, engagement analytics and qualitative indicators, which indicate kinetic text, format variations, and animation responsive were more interesting, easier to understand, and shareable than static texts. Findings suggest participants read as a participant and active, as opposed to passive, which wasn't related to their use of interactions. At last the results deliver positioning for interactive text read as a new thinking strategies for the needs of generation z for authenticity and enable discourse regarding potential opportunities for augmented reality and artificial intelligence-enabled personalization
