Abstract

Understanding the basic concepts of mathematics is the key to learning and applying mathematics in other disciplines. Many students today only rely on memorizing formulas without understanding mathematics concepts. One way to be introduced so that students do not just memorize and think math is boring is educational games. Community service conducted by lecturers of the Mathematics Study Program FMIPA Tanjungpura University to students of SMA Negeri 1 Singkawang West Kalimantan amis to increase motivation to learn matematis through educational games. The method used was in the form of educational seminars on educational games in the field of mathematics and exhibitions of mathematical teaching aids. Students are given some basic math problems that can be solved through games. Some concepts of algebra, geometry, and statistics were given as examples in applying educational games. In addition, some props to facilitate math solutions were also given, such as trigonometry, geometry, and algebraic calculation props. One of the results obtained is that students feel that activities like this need to be done so that student's interest in mathematics increases. Furthermore, this activity also gives a better understanding of the basic concepts of mathematics to other disciplines

Abstract

Forest fires are a persistent environmental issue in West Kalimantan, Indonesia, driven by both natural and human factors. Fire Radiative Power (FRP) serves as a vital indicator for assessing wildfire intensity and energy release. This study aims to model and predict the spatial temporal dynamics of FRP using the Generalized Space Time Autoregressive [GSTAR(1;1)] model combined with Ordinary Kriging interpolation. The dataset covers West Kalimantan from July 2024 to September 2025, comprising four attributes: observation date, longitude, latitude, and FRP value. Data filtering was applied from the national to provincial level, focusing on three regencies Sanggau, Sekadau, and Ketapang across 14 sub-districts represented by a 1.25×1.25 grid. The data consisted of 65 weekly observations, with 61 used for training and 4 for testing. The GSTAR(1;1) model with a spatial area-based framework achieved an optimal MAPE of 12.63% and satisfied the white noise assumption, indicating reliable performance. Predictions for October 2025 indicated relatively stable fire intensity, with a slight FRP decrease in Nanga Tayap and Sandai during the final week. Overall, the integrated GSTAR–Kriging framework effectively captured both temporal and spatial variations, supporting improved fire risk assessment and regional decision making for wildfire management in West Kalimantan.
