facilities, infrastructure, and public utilities through the principle of mutual cooperation. BSPS recipients must meet several criteria, such as income, house ownership status, house size, floor type, wall type, roof type, and water source. To address issues based on these criteria, Data Mining techniques using the Naive Bayes method were employed. This study utilized a dataset of BSPS recipients in Air Genting Village, Air Batu Sub-district, comprising 88 samples. The classification results from applying Naive Bayes yielded a precision value of 84%, a recall value of 81%, an F1-score of 82%, and an accuracy of 81%. The objective of this research is to facilitate the classification of eligible and rightful recipients of government assistance in the form of BSPS. The results of this study are expected to provide an alternative solution in determining BSPS recipients in Air Genting Village, Air Batu Sub-district
Abstract:The use of smartphones in Indonesia has been steadily increasing each year. In the era of the Fourth Industrial Revolution, smartphones have become a lucrative business sector, leading to intense market competition. Consequently,…
equently, smartphone companies must pay closer attention to the market segmentation desired by consumers. Data mining is the process of discovering significant relationships and patterns by analyzing large datasets using statistical and mathematical techniques. This study aims to identify and analyze the market segments of Android smartphone users among students at STMIK Royal. The data used in this research were collected from 122 student respondents. The study employs clustering using the K-means algorithm. The resulting data modeling will categorize market segments into several clusters. This segmentation yields three clusters: Cluster 1 (features), consisting of 36 respondents who prioritize price, battery, camera, and warranty; Cluster 2 (product), with 49 respondents who value all attributes except warranty; and Cluster 3 (superiority), comprising 37 respondents who prioritize camera, brand, and RAM.
Abstract:Efficient queue management is a major challenge in public services, including in Cibeunying District. Traditional manual systems often lead to unorganized queues, long waiting times, and public dissatisfaction. This study…
y aims to design and implement a more modern and structured technology-based queue numbering system. The system is designed as a web-based application that allows users to take queue numbers directly on-site or via mobile devices. Additionally, the system is equipped with an automatic call feature, where if a number is not present after two calls, the next number is automatically called. The implementation results show that this system can improve service efficiency, reduce waiting times, and provide a more convenient experience for the community. With this system, the Cibeunying District can significantly optimize the quality of its public services.

nd its stability will be seen. The article discusses the stability of fixed points using the Jacobian matrix and the Routh-Hurwitz criterion as well as the Castilo-Chaves and Song Theorems, reproduction numbers, and their numerical analysis. The results of the analysis show that the stability of fixed points is related to the basic reproduction number determined by the next-generation matrix, stability analysis in accordance with the theorem and the distribution of the population is shown in a numerical graph.
Abstract:The purpose of this research is to determine the effect of using the Group Investigation model on the ability to write book reviews at XIth Class of SMK Taman Siswa Suka Damai. The population in this study are all XIth class…
lass students, totaling 127 students. The sample in this research is XIth class Accounting which are taken using a simple random sampling technique totaling 22 students. The data collection technique uses a performance test in writing a book review. Based on the research results, at the pretest the average score obtained was 66.1 and at the posttest 90.31. The significant value obtained is greater than ttable, namely tcount > ttable, namely 80.7>1.68 and 80.7>2.41. This proves that Ho is rejected and Ha is accepted, namely that there is a significant influence from the use of the Group Investigation model on the ability to write book reviews in class.
Abstract:The aim of this study is to assess whether the application of the three-step interview method affects the ability to write observation report texts among 10th-grade students at Madrasah Aliyah Swasta Al-Washliyah Binjai…
Serbangan. This research is an experimental study using a posttest-only design. The population consists of three 10th-grade classes, with two classes selected as samples: X IPA 1 and X Agama, chosen randomly using simple random sampling. The X Agama class was taught using the three-step interview method, while the X IPA 1 class served as the control group with conventional teaching methods. After the completion of the instruction, the post-test results showed an average score of 87.5 for the experimental class and 61.29 for the control class. The t-test results revealed a Thitung value of 79.15, exceeding the Ttabel value of 2.00, which means the null hypothesis (H0) can be rejected and the alternative hypothesis (Ha) accepted. This indicates that the three-step interview method has a significant effect on the ability to write observation report texts among 10th-grade students at Madrasah Aliyah Swasta Al-Washliyah Binjai Serbangan.
Abstract:This study aims to analyze the impact of using the mind mapping method on the ability to write procedural texts by utilizing Canva media among 11th-grade students at Air Joman Private High School during the 2023/2024 academic…
demic year. This research employs a true experimental design with a posttest-only control group design, involving 124 students randomly selected to be placed in two classes: the control class and the experimental class. The results indicate that the experimental class, which implemented the mind mapping method with Canva media, had an average score of 81.84, higher than the control class, which only used Canva media without the mind mapping method, with an average score of 74.39. Statistical tests revealed that the mind mapping method had a significant impact on improving procedural text writing skills, with a to value of 106.42, far exceeding the critical t-value at the 5% significance level (2.01) and the 1% significance level (2.68). Therefore, the alternative hypothesis is accepted, demonstrating that the use of the mind mapping method along with Canva media is proven to be effective in enhancing students' ability to write procedural texts.
