Abstract

This study is motivated by the lack of previous researchers examining the level of visual thinking in students' mathematical communication. This research aims to describe the level of visual thinking in students' mathematical communication. The research method is literature research or literature review (literature review, literature research). Research activities were carried out in a structured way through the stages of data collection, data reduction, data display, discussion to conclusion. Technically, the research steps were carried out as follows: 1) the preparation stage, determining the fixed and dependent variables, determining the data to be analysed and selecting articles that are in accordance with the variables in the title, 2) the implementation stage, searching and collecting articles, taking the results of the articles obtained, and 3) the data analysis stage, this stage is used to determine the level of visual thinking and indicators of students' mathematical communication which will be useful to determine the level of visual thinking of students' mathematical communication. The results showed that there is a relationship between the level of visual thinking and students' mathematical communication, so that the levels of visual thinking in mathematical communication are: Non Visual Level, Local Visual Level, and Global Visual Level.

Abstract

Siswa harus belajar untuk berpikir secara aljabar karena berpikir aljabar menjadi bagian dari beberapa cara berpikir dalam pembelajaran matematika. Berpikir aljabar erat juga kaitannya dengan membuat pola generalisasi. Berpikir aljabar merupakan berpikir yang menyatakan keterkaitannya ke dalam hubungan umum, lalu membandingkan dan memanipulasinya. Oleh karena itu, penting bagi peserta didik untuk mengasah kemampuan berpikir aljabar. Namun faktanya kemampuan berpikir alajabar peserta didik masih rendah. Tujuan penelitian ini untuk melakukan investigasi terhadap kemampuan berpikir alajar peserta didik dalam menyelesaikan masalah matematika. Pendekatan yang digunakan adalah penelitian deskriptif kualitatif. Instrumen dalam penelitian ini yaitu satu soal cerita materi aljabar dan pedoman wawancara. Uji keabsahan data menggunakan validitas internal (credibility) dalam bentuk triangulasi teknik. Hasil penelitian ini menunjukkan bahwa peserta didik dengan kemampuan matematika yang baik juga memiliki kemampuan berpikir aljabar yang baik karena peserta didik mampu memenuhi semua indikator yaitu genarsional, transformasi, dan level meta global dengan tepat. Peserta didik dengan kemampuan matematika sedang hanya mampu memenuhi indikator transformasi, dan level meta global, namun dengan jawaban tidak tepat. Peserta didik dengan kemampuan matematika rendah memenuhi indikator transformasi, dan level meta global, namun dengan jawaban tidak tepat. Students must learn to think algebraically because algebraic thinking is part of several ways of thinking in learning mathematics. Algebraic thinking is also closely related to making generalization patterns. Algebraic thinking is thinking that expresses connections into general relationships, then compares and manipulates them. Therefore, it is important for students to hone algebraic thinking skills. However, the fact is that students' algebraic thinking abilities are still low. The aim of this research is to investigate students' natural thinking abilities in solving mathematical problems. The approach used is qualitative descriptive research. The instruments in this research were one algebra story question and an interview guide. Data validity testing uses internal validity (credibility) in the form of technical triangulation. The results of this research show that students with good mathematical skills also have good algebraic thinking skills because students are able to fulfill all indicators, namely genarsional, transformational, and global meta levels correctly. Students with moderate mathematical abilities are only able to fulfill the transformation indicators and global meta level, but with incorrect answers. Students with low mathematical abilities meet the transformation indicators and global meta level, but with incorrect answers.

Abstract

Concerns over the adverse effects of using synthetic dyes in food products—such as the risk of allergies and long-term health issues—have prompted the need for safer and more nutritious natural dye alternatives. This research aims to explore the innovation in adding Moringa Leaf Puree (Moringa Oleifera) in the making of Roti Jala as an effort to present traditional foods that are healthier and more functional. The research employed an experimental approach with three treatments, namely the addition of Moringa leaf puree at levels of 25%, 50%, and 75% of the total wheat flour. The results showed that the 25% Moringa leaf treatment was the most preferred formulation among the panelists, achieving an overall preference rate of 81%, especially in terms of color, texture, and taste. The ANOVA test indicated significant differences in color, aroma, and taste, but not in texture. Macronutrient content analysis revealed an increase in energy, protein, and fat corresponding with the higher addition of Moringa leaf puree, where the 75% sample yielded 872.2 kcal of energy, 210.7 g of protein, and 179.2 g of fat per 200 grams serving. This study demonstrates that Moringa leaf puree can serve as a natural coloring agent while enhancing nutritional value without diminishing the typical characteristics of Roti Jala. These findings are expected to contribute to the development of traditional culinary innovations that are healthy, economically valuable, and supportive of sustainable food product advancement.

Abstract

Mathematical concepts can be found in the culture of the community, such as in daily activities and handicrafts. One type of handicraft is the pencar, a cast net (throw net) fishermen use to catch fish. This research aims to explore the arithmetic sequences involved in making a pencar. This research uses qualitative research with ethnography. The research was conducted in Marong Village, West Nusa Tenggara, Indonesia. Data were obtained by direct observation of the pencar and the process of making it, interviews with cast-net handycrafters, and literature studies on arithmetic sequences. The results of this study show that there are three arithmetic sequences in the pencar. The first sequence, the number of anak (meshes) between each anakan (widener) in the n-th widener row, is 3, 4, 5, and so on, formulated by Un = 3 + (n - 1). The second sequence, the number of anakan (widener) in the n-th widener row is 44, 45, 46, and so on, formulated by Un = 44 + (n - 1). The third sequence, the number of lubang (meshes) in the n-th anakan is 44, 90, 138, 188, and so on, formulated by Un = n^2 + 43n. The arithmetic sequences in pencar can be used as a problem context for culture-based learning in the arithmetic sequence topic.

Abstract

Tegalweru Village is one of the citrus producing centers in Malang Regency, but has no innovation in processing crops that have an impact on community economic empowerment. This study aims to assess the effectiveness of orange roll jelly processing training as a form of business opportunity based on local potential. The research method used is descriptive qualitative, with data collection techniques through observation, interviews, documentation, and community empowerment. The training, which was held on January 19, 2023, was attended by 30 PKK mothers. The results showed an increase in participants' understanding of the manufacturing process and the business potential of the product. Orange roll jelly products are considered attractive, healthy because they are without preservatives, and have economic value. This training opens up opportunities for the formation of new MSMEs based on local potential and strengthens the empowerment of village women.
