The purpose of this research is to identify the difficulties encountered by students in solving higher-order thinking Skill (HOTS) questions, considering their mathematical communication abilities. This research employs a descriptive method with a qualitative approach and a case study research design. The subjects of this study are 25 eighth-grade students from SMP Negeri 3 Palu. Three students were selected to represent the high, medium, and low categories of mathematical communication abilities, allowing for an analysis of their difficulties in solving HOTS questions. The research instruments include a mathematical communication ability test, a HOTS question test, and interview guidelines. Data analysis consists of data collection, data reduction, and conclusion. The study results indicate that students with high mathematical communication abilities experience difficulties in question C6, particularly in applying mathematical principles. Meanwhile, students with medium mathematical communication abilities need help in question C5, which involves the application of mathematical principles, as well as in question C6, where they struggle with applying concepts and solving verbal problems. On the other hand, students with low mathematical communication abilities encounter difficulties in questions C4 and C6, which require the application of mathematical concepts and principles and solving verbal problems. Developing students' critical thinking skills and mathematical literacy can mitigate these difficulties. Students can better grasp mathematical concepts by applying analysis and evaluation in critical thinking. Additionally, engaging in interpretation within mathematical literacy can enhance their ability to solve verbal problems more effectively.

Abstract

PT. Sinar Gunung Sawit Raya (SGSR) is a company operating in the palm oil plantation sector, producing palm oil and palm kernels. The company faces the challenge of palm oil production variability related to seasonal fluctuations, particularly in the number of fresh fruit bunches (FFB) from oil palm plantations and the FFB delivered to the mill. Palm oil production is significantly affected by seasons, with production increasing during certain months, such as the rainy season when oil palm fruits are larger and heavier, resulting in higher oil yields. Conversely, during the dry season, the fruits tend to be smaller and lighter, leading to a decline in palm oil production. This research aims to forecast palm oil production for the following two periods using the Holt-Winters Exponential Smoothing method with both additive and multiplicative models. Forecasts are conducted manually and with the assistance of Microsoft Excel software. The forecast accuracy is assessed using the Mean Absolute Percentage Error. The manual forecasts for the additive and multiplicative models yielded error rates of 2.11% and 11.56%, respectively. While these forecasts provide valuable insights, it should be noted that other factors may also influence palm oil production outcomes. Therefore, these forecasting results can assist the company in formulating policies to enhance palm oil production.

Abstract

The Generalized Space-Time Autoregressive Integrated Moving Average (GSTARIMA) is a model used to model time series data that exhibits spatial dependencies among its locations as well as temporal dependencies. GSTARIMA is applied in various economic contexts, including analyzing exports and imports, exchange rates, production, inflation, and rainfall. This research aims to develop the best GSTARIMA model and utilize it to forecast rainfall in the Medan Belawan District. The GSTARIMA model combines temporal and geographical aspects by adjusting parameters for each observed location. The data used in this study consists of monthly rainfall data for the Medan Belawan District, obtained from the Maritime Class II Meteorological Station in Belawan, spanning from January 2020 to December 2022. The identification of Autoregressive (AR) and Moving Average (MA) orders was performed through the analysis of the Autocorrelation Matrix (MACF) and Partial Autocorrelation Matrix (MPACF). This study employed a spatial order of 1, along with an inverse distance weighting matrix and cross-correlation normalization. Parameter estimation used the generalized least squares (GLS) method. The research results indicate that the GSTARIMA model (2,0,0) with the inverse distance weighting matrix achieved the lowest Mean Absolute Percentage Error (MAPE) rate, specifically at 1.0170. Thus, this model is considered the best for forecasting rainfall in the Medan Belawan District.
