Purpose: This study aimed to design and develop a math monopoly board game as a learning tool to boost students’ mathematical communication skills. The motivation for this research comes from the need to improve both written and oral communication abilities in mathematics among middle school students. Method: The research followed a research and development (R&D) approach using the ADDIE model, which includes the phases of Analysis, Design, Development, Implementation, and Evaluation. The math monopoly game was created and validated by experts in the field, and then tested with eight eighth-grade students from SMP Muhammadiyah 09 Gondanglegi, selected using purposive sampling. Data were collected using validation sheets, questionnaires, and interview guides. The effectiveness of the game was assessed using descriptive statistics and paired sample t-tests to measure students’ mathematical communication before and after the intervention. Findings: The findings showed that the developed monopoly game was highly valid and practical as a learning medium according to both experts and students. Playing the game led to a significant improvement in students’ written mathematical communication, as seen in their increased test scores after using the game. However, there was little change in students’ oral mathematical communication, suggesting that simply playing the game is not enough to foster verbal interaction, and that additional support from teachers during play is important. Significance: This research highlights the potential of game-based learning to make mathematics lessons more engaging and to improve students’ ability to express mathematical ideas in writing. It also points out the need for teacher involvement and further strategies to help students improve their oral communication in mathematics.

Purpose – This study investigates the implementation of Integrated Financial Digital Services and e-Money (IFDS-e M) as an innovation strategy to pioneer a circular school model at SD Aisyiyah Gemolong. It addresses Indonesia’s ecological crisis and unsustainable consumption patterns by combining digital transformation with circular economy principles in basic education. Design/methods/approach – Using a descriptive qualitative case study, the research was conducted at SD Aisyiyah Gemolong, a high-performing elementary school with 1,030 students in Central Java. Data were collected through participatory observation, in-depth interviews, documentation, and questionnaires. Data analysis employed the Miles and Huberman model to interpret emerging patterns and evaluate program impact. Findings – The IFDS-e M system successfully digitized school transactions, reduced the use of cash, and shaped environmentally conscious behaviors among students. The ban on pocket money led to a measurable reduction in food packaging waste, while school-owned enterprises (BUMS) enhanced service efficiency and internal resource circulation. Over 95% of school financial transactions were processed digitally, improving transparency and minimizing paper use. Challenges such as intermittent internet connectivity emerged during peak access times but did not hinder overall program outcomes. Research implications – The IFDS-e M model offers a replicable strategy for schools to advance sustainable behavior and reduce environmental impact. It informs educational policy and practice on integrating digital tools with ecological values to cultivate responsible consumption from an early age.

Mathematics is a supporting science for other branches of science as a medium for communicating mathematical problem solving. One of the abilities that must be possessed by students is the ability to communicate in trigonometry material. In this research, only 36.7% of students correctly identified the transformation of trigonometric function graphs in question number 9. However, there were some students whose explanations were not precise because their understanding of the material was not correct. The purpose of this study is to analyze the mathematical communication skills of grade X MA students in the material of trigonometric function graphs. In this research, a qualitative research type with a descriptive approach is used. The test of mathematical communication ability in writing is in the form of a test that is done independently and tested on 6 students with a group of 2 high ability students, 2 medium ability students, and 2 ability students with the need for further guidance. While the test of mathematical communication skills orally answered together through the interview method. The significance of this research is the students become more focused in learning because students are instructed to do activities by shifting the slider so that the intended graph is formed according to the instructions of the given problem. The conclusion drawn from the results of the research conducted is that mathematical communication in the material of trigonometric function graphs is relatively low, both in writing and orally. This is based on the percentage in the analysis test of mathematical communication skills in writing where students answered 10 out of 18 items had below 50% incorrect written response rates, compared to 8 other items that students could answer correctly with a score above 50%, while in the oral mathematical communication ability analysis test there are still misconceptions in every question asked. This is based on this research data that some students still answer the items incorrectly.

This study aims to analyze the written mathematical communication of eighth-grade junior high school students regarding the topic of triangle construction congruence. Data collection was conducted through two methods: a written test to measure mathematical communication and observation to assess students' socio-emotional aspects using a problem-based learning model. This study employed a descriptive method with a qualitative approach. Data analysis techniques were carried out through data reduction, data presentation, and drawing conclusions, with classification based on high, medium, and low categories in mathematical communication indicators. Based on the analysis results, students with high socio-emotional levels demonstrated strong mathematical communication, enabling them to express and interpret mathematical ideas in writing and use mathematical symbols in problem-solving. Conversely, students with low socio-emotional levels showed difficulty in expressing mathematical ideas in writing. The conclusions of this study indicate a relationship between socio-emotional levels and students' mathematical communication abilities. Consequently, teachers need to consider integrating socio-emotional approaches into learning to optimally and equitably improve students' mathematical communication.

The ability to communicate mathematical ideas orally is crucial for studying mathematics. One way to measure oral communication skills is by presenting an open-ended problem to students. This study aims to illustrate how students solve open-ended issues using oral mathematical communication skills. The methodology is a qualitative descriptive study; the subject of the research is grade VIII junior high school students with low, medium, and high levels of mathematical ability to communicate when working on open-ended problems. From this study, students who have a low level of communication ability have not met all the indicators optimally, because the understanding of symbols and their use is still weak. Students in the medium level that satisfy the markers of mathematical communication, because the notation used is appropriate and consistent and students can provide concise, clear, and thorough explanations. Students with high categories meet all indicators very well, because they are able to use complete and accurate mathematical symbol and students can provide concise, clear, and reflective explanations. Students in lower categories' have not fully satisfied all of the requirements for mathematical communication. The medium-level pupils satisfy the requirements for mathematical communication. Students with high categories meet all mathematical communication indicators very well.

Waste management issues in Serang Regency, particularly in Desa Cerukcuk, have become a major concern due to the increasing volume of waste that polluting rivers, roadsides, and residential areas. To date, Serang Regency does not have land or facilities for a permanently operating Final Waste Disposal Site (TPSA). This situation has significant environmental impacts and indicates a gap between infrastructure needs and policy implementation practical reality. This study aims to evaluate the commitment of the Serang Regency This community service program focuses on optimizing independent fish feed production through the implementation of a Recirculating Aquaculture System (RAS) combined with a mini Solar Power Plant (PLTS) in Parangargo Village, Wagir District, Malang Regency. The program was designed to address the challenges of high commercial feed costs and dependence on grid electricity that have burdened local fish‐farming groups. The activities included socialization, training in independent fish feed production, installation of the RAS and mini PLTS technologies, business management mentoring, and outcome evaluation. The results show that energy efficiency increased by 20–30% after the installation of the mini PLTS, while feed costs decreased by 10–15% due to the availability of self-produced fish feed. The RAS technology also improved water quality and reduced fish mortality, leading to approximately a 10% increase in production per cycle. Moreover, the managerial and digital marketing skills of the partner groups—“Minaargo” Fish Farming Group and “Matoon” Youth Organization—significantly improved. This program strengthens the village’s food and energy independence and supports the achievement of the university’s Key Performance Indicators.
