Tujuan penelitian untuk mengetahui kemampuan siswa ketika memecahkan masalah aritmetika sosial berdasarkan teori APOS. Penelitian menggunakan jenis kualitatif deskriptif. Teknik pengumpulan data menggunakan 2 soal tes tulis, dokumentasi, dan pedoman wawancara. Subjek dalam penelitian ini sebanyak 18 siswa kelas VIII A. Peneliti menganalisis hasil tes dan memilih 6 subjek untuk diwawancarai dengan masing-masing 2 siswa berkemampuan rendah, sedang, dan tinggi. Hasil penelitian menunjukkan siswa berkemampuan: a) Tinggi mampu memecahkan masalah disetiap nomor di tahap APOS. 2) Sedang mampu mencapai tahap aksi dan proses akan tetapi pada proses gambaran strategi yang diberikan masih salah dan subjek belum mampu mencapai tahap O dan S. 3) Rendah mampu mencapai tahap A dan P, hanya 1 subjek yang memberikan gambaran strategi, namun gambaran strategi yang diberikan masih salah, subjek tidak mampu mencapai indikator pada tahap O dan S. Mayoritas siswa berkemampuan sedang mengalami kesalahan di tahap proses dimana siswa tidak dapat menggambarkan penyelesaian soal.

Ethnomathematics is important because of the need to integrate real cultural values in learning mathematics. West Java is one of the provinces in Indonesia which has a variety of ethnomathematics, one of which is Indramayu. Some of the people of Indramayu still use the traditional rice measurement tool so that it can become an ethnomathematics study. Therefore, the aim of this study is to describe the results of an ethnomathematics study on the use of rice measuring instruments in the communities of several Indramayu regions. This research method is ethnography with five female and one male participants. Data collection was carried out by triangulation, namely documentation, interviews, field notes, and observations. The result of this research is that there is ethnomathematics in the use of traditional rice measurement tools in the Indramayu community. So that further research is needed to apply ethnomathematics to learning mathematics on the topic of introducing volume units, mass units, and fractional numbers in the area.

Reversible thinking is a type of mental activity that has an important role in a person's success in solving problems. Problem solving is the heart of learning mathematics. Reversible thinking must be developed so that students have good problem solving skills. The purpose of this research is to describe the back-and-forth thinking of junior high school students in solving statistical problems. This type of research is descriptive qualitative with instrument tests. The research subjects were class VII students of SMPN 1 Gudo Jombang. Data collection by giving a test in one class VII SMPN 1 Gudo as many as 33 students. Next, one student who has the highest score is selected to be analyzed more deeply regarding his reversible thinking. The results of the study were that 78.9% of students were able to complete the first question, which was a question where the answer could be directly determined (data was known, the average was asked), but only 45.5% and 30.3% of students were able to complete the next two questions respectively. , which in solving it requires reversible thinking. The next two problems are problems that are the opposite of the first problem. Based on the test results, one student was selected with the highest test score, namely AAN. AAN is able to solve all problems correctly, both from the aspect of the settlement procedure and the final result. AAN has involved aspects of reversible thinking well in solving statistical problems. Among these aspects are forward, backward, and reverse aspects.

Farmer welfare is a condition of a farmer in a prosperous, healthy and peaceful condition without social jealousy in the community. However, this is difficult to materialize for farmers because of a number of factors, namely the ineffective and inefficient fertilizer subsidy policy with farm needs and the different characteristics of farmers in conducting farming.The purpose of this study was to analyze the level of welfare of tobacco farmers in Jombang Regency measured by the large farmer exchange rate (NTP) with several variables including the fertilizer subsidy policy variable, and the farmer characteristics variable.From statistical testing using ordinal logistic regression. The research data was obtained with 123 questionnaires distributed in Sawahan Hamlet Sumbergondang Village, Kabuh District, Jombang Regency.From the partial test, it was explained that the variables which were made into research did not significantly influence the farmer exchange rate (NTP). The results of the coefficient of determination show the results of the coefficient of determination Nagelkerke of 0.900 or 90.0%. It means that the independent variable (fertilizer subsidy policy, and the characteristics of farmers) affects the farmer exchange rate (NTP) of 90.0% while 10.0% is influenced by other factors not included in this research variable.

The data from the Mamba'ul Ma'arif Islamic Boarding School website page is that it houses 16 dormitories with male and female classifications. Some of the important factors include sowan, mineral water delivery, and garbage collection with several different access points. Therefore, of course, it is necessary to consider the shortest route, so that it can save time and minimize the distance to get to the dormitories. Graph theory, which is a branch of mathematics that can be implemented to find the shortest route. Researchers conducted research to determine the shortest route using the nearest neighbor method. The result of the shortest total distance from the implementation of the nearest neighbor method, the shortest route between the Mamba'ul Ma'arif Foundation dormitories Denanyar Jombang, is 1,920 meters. The aim of the results of this study can be used as a reference for the parties concerned to get the shortest route at the Mamba'ul Ma'arif Foundation, Denanyar Jombang.

SMP Negeri 10 Tanjungpinang has varied mathematical literacy because learning at school still sees students' abilities due to the impact of Covid-19. Students are facilitated with questions in the form of AKM but students tend to understand the questions less because of the long narrative. This study describes students' mathematical literacy in solving Minimum Competency Assessment (AKM) model questions on geometry content. The approach used in this is qualitative with descriptive method. The research subjects were 3 students consisting of high, medium, and low categories. Data collection techniques in the form of tests and interviews. Data analysis techniques used data reduction, data presentation, and conclusion drawing. Researchers ensured the validity of the data, using triangulation techniques by equalizing the results of tests and interviews. The result of this study is the classification of students' mathematical literacy based on categories. Students in the high category have good literacy where they are able to fulfill all three indicators, namely formulating problems, applying concepts, and interpreting solution results. While students in the medium category are able to fulfill both indicators, namely formulating problems and applying concepts and have not fulfilled the indicator of interpreting the results of the solution. Low category students were only able to fulfill the indicator of formulating problems and did not fulfill the indicators of applying concepts and interpreting the results of the solution.
