Abstract

Pegalongan village is located in the south of Purwokerto city and the majority of the population work as farmers. Rice farming in this area is an important part of local culture and tradition, as well as a major source of livelihood for the local community. The purpose of this study is to find the mathematical elements hidden in the operation of rice farming and the philosophical value contained in it. To understand how rice farming communities use mathematics in their cultural context, this study used a descriptive qualitative ethnographic approach. The research involved farmers and farm labourers. The focus of the research includes the planting land, and the process of planting rice, the cultivation of the farmers in the form of mimiti and mbawoni. Data was collected through direct observation of farmers, documentation, and in-depth interviews. Data were analysed thematically to find key themes related to ethnomathematics in rice cultivation. These themes included the use of mathematics in agricultural activities, the use of traditional tools and units of measurement, and agricultural processes rooted in local culture. The study also emphasised that ethnomathematics should be part of the education curriculum to improve students' understanding. The results showed that mathematical concepts such as arithmetic, and measurement can be applied in land cultivation. The results show that local knowledge is critical to agricultural practices, and how ethnomathematics can be incorporated into the education curriculum to improve students' understanding of mathematics in a cultural context.

Abstract

The use of phosphorus and zeolite can be an option to improve soil fertility and nutrients for pagoda mustard plants. This study aims to determine the effect of phosphorus and zeolite on the growth and yield of pagoda mustard. This study used a factorial completely randomised design with three replications. The first factor is phosphorus, consisting of three levels: F0 (control), F1 (60 g/polybag), and F2 (100 g/polybag). The second factor is zeolite fertiliser, consisting of three levels: L0 (control), L1 (50 g/polybag), and L2 (90 g/polybag). The two factors resulted in nine treatment combinations. The combination of the two factors totalled nine treatments, which were then repeated three times, resulting in 27 experimental units. The observation variables were plant height, number of leaves, plant fresh weight, root fresh weight and root length. The results showed that there was no interaction between phosphorus and zeolite application on the growth and yield of pagoda mustard plants. The addition of phosphorus fertiliser did not significantly affect all observation variables in this study. The addition of zeolite fertiliser showed a significant effect on the variable number of leaves, plant fresh weight, and root fresh weight where treatment L2 (90 g/polybag) showed the highest effect.

Abstract

This study aims to analyze students' mathematical problem-solving skills based on the level of math anxiety they experience. Math anxiety is a psychological factor that can affect students' academic performance in mathematics, especially in that require problem solving. The research method is qualitative with a descriptive approach. Data collection was carried out through tests, questionnaires, and interviews. The results of the math anxiety questionnaire categorized students into high, medium, and low categories. Respondents were collected by purposive sampling from each category of math anxiety. Data analysis consists of reduction, data presentation, and conclusion. The results showed that students with low math anxiety were able to solve problems more systematically and flexibly, while students with high math anxiety tended to have difficulty understanding problems and designing solution strategies. Students in the math anxiety category are having difficulty in implementing a completion plan and providing the right conclusions. These findings confirm that math anxiety has a significant impact on students' mathematical problem-solving skills. Abstrak: Penelitian ini bertujuan untuk menganalisis kemampuan pemecahan masalah matematika siswa berdasarkan tingkat kecemasan matematika yang dialaminya. Kecemasan matematika merupakan faktor psikologis yang dapat mempengaruhi prestasi akademik siswa dalam matematika, terutama dalam memecahkan masalah. Metode penelitiannya bersifat kualitatif dengan pendekatan deskriptif. Pengumpulan data dilakukan melalui tes, kuesioner, dan wawancara. Hasil kuesioner kecemasan matematika mengkategorikan siswa ke dalam kategori tinggi, sedang, dan rendah. Responden dikumpulkan dengan purposive sampling dari setiap kategori kecemasan matematika. Analisis data terdiri dari reduksi, penyajian data, dan kesimpulan. Hasil penelitian menunjukkan bahwa siswa dengan kecemasan matematika rendah mampu memecahkan masalah secara lebih sistematis dan fleksibel, sedangkan siswa dengan kecemasan matematika tinggi cenderung mengalami kesulitan memahami masalah dan merancang strategi solusi. Siswa dalam kategori kecemasan matematika mengalami kesulitan dalam menerapkan rencana penyelesaian dan memberikan kesimpulan yang tepat. Temuan ini menegaskan bahwa kecemasan matematika memiliki dampak yang signifikan pada keterampilan pemecahan masalah matematika siswa.

Abstract

This study explores the challenges faced by vocational students in solving contextual problems in statistics using the TEFA (Teaching Factory) approach, aimed at enhancing their analytical and problem-solving skills—competencies that are highly valued in the industrial world. The purpose of this research is to analyze the difficulties students encounter when solving TEFA-based contextual problems in statistical topics. The subjects of this study were 38 tenth-grade students from class X TO 9 at SMK Kesatrian Purwokerto, selected based on their even semester daily test scores. The students were categorized into three groups: high (HC), medium (MC), and low (LC), based on the class average and standard deviation. This research employed a qualitative descriptive method. The findings revealed that students in the high category were generally able to understand statistical concepts and accurately calculate the mean, median, and mode. However, some students in this group did not sort the data from smallest to largest when calculating the median. Students in the medium category had difficulty recalling how to compute the mean, often resulting in incorrect answers; although the mode was correct, the median was not. Meanwhile, students in the low category acknowledged that they lacked understanding of how to calculate the mean, median, and mode.

Abstract

The purpose of this study was to determine the mathematical creative thinking ability of Kesatrian Purwokerto High School students on the topic of trigonometry using the Discovery learning model and Probing-Prompting technique. The research design used true experimental design type post test only control design. The research sample was X TJKT 1 class of 37 students and X TJKT 2 class of 36 students and used cluster random sampling technique. Of the two classes taken TJKT 1 class as an experiment, TJKT 2 class as a control.The results showed: 1) There is an effect of Probing Prompting learning model on students' creative thinking skills, 2) There is an influence of the discovery learning model on students' thinking skills. The conclusion of this study shows that the ability to think creatively using the probing prompting technique is better than the class that uses the discovery learning model.
