Abstract

Geometry is one of the fundamental topics in mathematics, playing a crucial role in understanding shapes, sizes, positions, and spatial relationships between objects. Mastery of this concept is essential; however, in practice, many students still struggle to grasp geometry material. This issue is also evident at SMA Negeri 1 Pujut, where several students demonstrate a low level of understanding of geometric concepts. In response to this problem, the aim of the research is a community service activity was carried out in the form of tutoring sessions focused on improving students' understanding of geometry. This activity employed a visualization approach through function graph sketches to help students better comprehend the interconnections between concepts in a more concrete way. Based on the evaluation results, data showed that 86.67% of students exhibited improved learning outcomes after participating in the activity. This achievement indicates that the instructional method used by the facilitators was quite effective and well-received by the majority of participants.

Abstract

This study uses Python to calculate and analyze three indices such as the first Zagreb, Wiener, and Gutman indices on the rank graph of the group modulo the power of a prime number. It relies on formulas that have been developed by previous research. By using Python libraries such as NetworkX, Matplotlib, and Tkinter, the calculation process becomes more efficient and allows visualization of index variations based on changes in the values of prime p and exponent k. The results show that the values of the three indices increase as the values of p and k increase, reflecting the increasing complexity of the graph structure. At large values of p and k, the graph visualization is too complex which causes the graph visualization to be less clear. This approach proves to be effective in supporting visual and quantitative exploration of algebraic structures.

Abstract

Rice is one of the crops that plays a significant role in maintaining food security and supporting Indonesia’s economy. As the staple food for the majority of the population, rice strongly influences the country’s social and economic conditions. Due to its crucial importance, accurate predictions of rice production are required to support more effective planning. This study aims to forecast rice production in West Lombok Regency using the least square method. The data utilized include harvested area and rice production from 2011 to 2022. The resulting prediction model is a second-degree polynomial function that represents the relationship between harvested area and total rice production. Based on the Mean Absolute Percentage Error (MAPE) analysis, an error rate of 2.2391% was obtained, indicating that the model has a very high level of accuracy, as the error is below 10%. The findings of this study are expected to serve as a reference for more precise planning to improve rice production in West Lombok Regency
