Abstract

This study aims to determine the best method in the forecasting system by creating a mathematical model of time series data in the form of Indonesia's Human Development Index (HDI) in 2010-2017. The methods tested are Moving Average (SMA, WMA and EMA), Exponential Smoothing Method (SES and DES), Naive Method, and Artificial Neural Network (Back Propagation). Then to see the level of accuracy based on MAD, MSE, and MAPE of each method. Determination of the best method in the forecasting system is very helpful in the process of forecasting data in the field which has implications for the government's decision system in making policies or decisions especially in the population, education, and people's economies. The best simulation method for predictions is the Exponential Smooting Holt Method with the predicted results of 2018 of 71.42 with the smallest MAD, MSE, and MAPE of 0.037; 0.001; and 0.053.

Abstract

The problem underlying this study is the suboptimal use of instructional duration in enhancing student engagement and participation, particularly in the context of game-based learning. Moreover, there is a lack of research that specifically examines the impact of short-duration differences on student engagement patterns, both individually and in groups. Therefore, this study aims to compare the levels of student engagement and participation in mathematics learning based on differences in duration and intensity of MathQuest game usage. This study employed a quantitative approach with an experimental design. The research subjects were 49 sixth-grade elementary school students divided into two groups, namely Class A and Class B. Data were collected using observation sheets and pre-test and post-test instruments developed based on validated indicators of student engagement (X1) and participation (X2). The collected data were analyzed using descriptive statistics and the Independent Sample t-test to determine the significance of differences between the two groups. The analysis results showed significance values for individual engagement (0.977), group engagement (0.084), individual participation (0.834), group participation (0.834), and participation within the group (0.145), all of which were greater than 0.05, indicating no significant differences in the average levels of engagement and participation between students in Class A and Class B, both individually and in groups. Although there were slight variations in mean scores and standard deviations, these differences were not substantial enough to influence the conclusions of the study.

Abstract

The low logical thinking skills and learning interest in mathematics have become a major issue in the students’ learning process. This study aims to analyze the effect of open-ended approaches and supportive learning environments on students’ logical thinking skills and learning interest in mathematics. This research employs an experimental design with a quasi-experimental approach. The subjects consisted of students divided into experimental and control groups. Data were collected using logical thinking tests, learning interest questionnaires, and learning environment observations as research instruments. Data analysis was performed using multiple linear regression, t-tests, and N-Gain analysis. The results indicate that simultaneously, open-ended approaches and supportive learning environments have a significant effect on logical thinking skills (R² = 66.6%; p = 0.000) and learning interest in mathematics (R² = 37.5%; p = 0.009). Individually, the open-ended approach positively affects logical thinking skills (B = 0.789) but negatively influences learning interest (B = -0.482), while the learning environment positively contributes to both. The t-test revealed a significant improvement in logical thinking skills in the experimental group compared to the control group (p = 0.001), and N-Gain analysis reinforced these findings by showing higher and more consistent learning outcomes in the experimental class. The study concludes that a combination of open-ended approaches and supportive learning environments is effective in enhancing students’ cognitive and affective aspects. The study’s implications emphasize the importance of teachers considering student readiness and creating a supportive learning environment to optimize and enrich mathematics learning experiences.

Abstract

Nowadays, there are often accidents such as the sinking of ships in water areas that are caused by weather factors, one of which is the extreme wind speed. Wind speed and strong waves in the sea are interrelated because the factor that affects the strength of the wave blow is wind speed. This study aims to provide information about the angina speed regression model to find out the wave height at the sea crossing port. This research is a quantitative research. The data used is in the form of wind speed data taken at the coordinates of Lembar Port and Labuan Bajo Port from the NASA sub-agroclimatology website from January 1, 2012, to December 31, 2021 (for 10 years). This case study uses linear regression analysis and is operated using SPSS software. The data shows that in Lembar Port has the most extreme wind speed fluctuations in the 6th and 7th years. While the wind speed fluctuations in Labuan Bajo are consistent, but slightly extreme in the 7th year surpassing the 1st year. The results showed that the R-Square of Lembar port was 15.4% while the R-Square of Labuan Bajo port was 16.2%. The results of this study can be used in formulating marine transportation safety policies in both regions.

Abstract

There have been many applications of card-based learning methods in education, one of which is in mathematics lessons. However, no one has discussed more specifically the impact of card-based learning methods with many variations, such as making math, card sorting, index cards, flashcards and other cards in mathematics lessons. This research aims to analysed how card-based learning methods significantly impact mathematics learning. The methods used in this research are quantitative and meta-analysis. Data sources are research results relevant to the research topic and meet the inclusion and exclusion criteria. Data were analysed using JASP software by inputting Effect Size (ES) and Standard Error (SE) values. The data collection method uses a literature study. The cumulative data analysis of the card-based learning method showed many variations in mathematics learning, totalling 68%. The analysis results based on the type of card that has the highest influence on mathematics learning is card sort, with a percentage of 73% in the medium category. These results show that the card-based method significantly impacts mathematics learning. So, the results of this research can be used as a reference for applying card-based methods in mathematics lessons.
