Utilization of the animal 4D application as an approach to increasing English vocabulary for elementary school children. However, problems also often arise, namely that a teacher's efforts to collaborate with students are very minimal, and managing responsibilities is difficult to implement because students have different points of view regarding the use of the Animal 4D application. Then there are other problems that also have an impact on students' academic knowledge, so that students' thinking becomes complicated to understand. Apart from that, raising student enthusiasm requires a supportive environment, but high academic demands are a challenge for students to face new concepts. This research aims to examine the influence of using the Animal 4D application to improve the English vocabulary of elementary school children. Apart from that, researchers also admit that in the educational environment, especially elementary schools, it is very necessary to apply English vocabulary which becomes a reference for these schools to increase the use of the animal 4D application. This research method uses a quantitative method, namely this method is an indication for respondents that this research is in the form of numbers. This was obtained through observations in the classroom and outside the classroom to find out how collaboration and cooperation between teachers and students went well during learning based on the Animal 4D application. Next, the researchers conducted interviews with teachers and students regarding the use of the animal 4D application to improve elementary school children's English vocabulary, as well as collecting quantitative data by distributing online-based questionnaires in the form of Google forms. The results of this research explain that the use of the animal 4D application has an impact on the motivation of elementary school students. When students are able to collaborate with other students, these students are able to develop innovative thinking skills and foster a sense of caring for each other. The conclusion of this research shows that a combination of good collaboration in learning based on the use of the Animal 4D application has great potential to increase students' creativity in mastering English vocabulary.

A/B checking is a regular measure in many marketing procedures for e-Commerce companies. Through well-designed A/B research, advertisers can gain insight about when and how marketing efforts can be maximized and active promotions driven. Whilst many algorithms for the problem are theoretically well developed, empirical confirmation is typically restricted. In practical terms, standard A/B experimentation makes less money relative to more advanced machine learning methods. This paper presents a thorough empirical study of the most popular multi-strategy algorithms. Three important observations can be made from our results. First, simple heuristics such as Epsilon Greedy and Thompson Sampling outperform theoretically sound algorithms in most settings by a significant margin. In this report, the state of A/B testing is addressed, some typical A/B learning algorithms (Multi-Arms Bandits) used to optimize A/B testing are described and comparable. We found that Epsilon Greedy, be an exceptional winner to optimize payouts in this situation.

The development of education in today's era has improved quite well, although there are still many who have not been able to keep up with the course of education that is being developed now. Technological development is also progressing rapidly. WebGIS is an important thing that is really needed in this digitalization era, it functions as information, especially in this discussion in the field of education. On current school information, the barrier is trying to eliminate the social gap in the form of a favorite school. This research was developed to make it easier for new students to graduate from junior high school to high school education and also make all schools equal without such a thing as a favorite school. with their address. This research uses the Web and Map which will be able to find out the distribution of schools according to the zoning area. The way this WebGIS works is that the user inputs the appropriate name and address into the web, then the system will provide information in the form of zoning for the closest school to the user's distance, which is expected that students will not choose the wrong school on the zoning path which allows low chances of entering the school.

The use of masks is still very strict in public places, especially in hospitals, this is solely done to prevent the spread of the corona virus again. The purpose of this research is to assist examination workers or health protocol workers in supervising the use of masks in public places. Mask detection is a solution to this problem, by utilizing computer vision technology and applying supervised learning algorithms. For this mask detection classification method, this system uses the Naive Bayes method. The output of this mask detection system is planned to distinguish people wearing masks and not wearing masks, by giving red labels to people who are not wearing masks and green labeling to people wearing masks. The distance aspect is used in testing this mask detection system, the system is able to work well by getting an error rate presentation below 2% and getting the highest accuracy of 100% with an average percentage value of 98%. On the other hand, there are still weaknesses in this system, the use of brown masks that are in harmony with skin color can worsen the results of the classification system

Classifying date fruit varieties is a challenging task due to their high visual similarity in terms of texture and color. This study aims to address this issue by developing an automated classification model that combines handcrafted Gray Level Co-occurrence Matrix (GLCM) texture features and average RGB color channels with Convolutional Neural Network (CNN) classifiers. The dataset comprises 1,658 images from nine varieties of date fruits, divided into 70% training and 30% testing subsets. The proposed workflow includes image preprocessing (resizing, normalization, grayscale conversion), extraction of GLCM features (contrast, energy, homogeneity, correlation), computation of average RGB channels, feature fusion, and CNN training using VGG16 and VGG19 architectures with Adam and Adadelta optimizers. The model performance is evaluated using accuracy, precision, recall, F1-score, and confusion matrix. Experimental results demonstrate that VGG19 with the Adam optimizer achieved the highest validation accuracy of 91%, slightly outperforming VGG16 (90%) but remaining below the 96% accuracy reported in prior studies using MobileNetV2. The integration of handcrafted features enhanced sensitivity to subtle color and texture variations, although it introduced potential feature redundancy. In conclusion, the hybrid GLCM–RGB–CNN with VGG19 and Adam achieved 91% accuracy, proving the benefit of combining handcrafted and deep features while highlighting opportunities for further enhancement through data augmentation and architectural optimization.

Fires are very detrimental, ranging from loss of property to even loss of life. Fires can be detected when the fire has grown or smoke has billowed out of buildings. Urban areas have densely populated housing so that it has the potential to cause problems in the event of a fire. These fires can be caused by by factors of human negligence and natural factors. Such as the occurrence of short-circuited electricity, negligence in cooking, negligence in burning garbage, and others. Therefore, we need a tool that can detect the presence of an early source of fire so that it does not spread. The problem that often occurs is when a fire occurs, the fire department often arrives late, so there are many losses due to the fire. And the losses can be material and economic. Therefore we need a system that works to control the fire automatically and to extinguish the fire in every house. This study aims to design and build an efficient and affordable prototype. Which later can be applied to housing or warehouses. This prototype is designed using NodeMCU ESP8266 as the main controller, Flame sensor can respond to infrared light beams on the modulation spectrum from 5 to 30 cycles per second, Web Thinger.Io as a server, data storage on the internet of things , and notification of fire in the Blynk application. This system uses a flame sensor based on the Node MCU ESP8266 microcontroller and is equipped with a Buzzer for Alarm and a Mini Water Pump to automatically spray water if a fire is detected. This system utilizes the Blynk Application as an interface to provide notification information about a fire to find out notifications if a fire is detected. And if a fire is detected, it will automatically get a notification from the Blynk application on the "There is Fire" Smartphone and the buzzer will automatically sound and the mini water pump will automatically spray water. In this study, the tool can automatically send Safe and Fire notifications using the blynk application on a smartphone with a delay of < 3 seconds.
