Abstract

This research aims to develop PMR-based learning tools (Realistic Mathematical Approach) on sequences and series material to determine the level of validity, effectiveness and practicality of PMR-based learning tools, increase students' mathematical communication skills using the developed learning tools and process student answers. in solving questions on mathematical communication skills, and student responses to learning using PMR-based learning tools.This research is research using the research and development (RD) method using the ADDIE development research model: Analyze, Design, Development, Implementation, and Evaluation. The subjects of the research were 21 students in class VIII of SMP IT Khairul Imam for the 2022/2023 academic year. The types of data are qualitative data and quantitative data, data is analyzed qualitatively and quantitatively. The research instruments used were lesson plan assessment sheets from material and media expert lecturers, mathematics teachers, colleagues, tests of students' mathematical communication skills and student response questionnaires.The research results show that: (1) The PMR-based learning tools developed obtained interactive learning which was declared valid with an average of 4.31; (2) The PMR-based learning tools developed meet the criteria for learning practicality in terms of analysis of the results of observations of learning implementation. The value obtained in trial I was 3.03 (medium category). In trial II, the observation value for learning implementation increased to 3.88 (the "high" category); (3) The PMR-based learning tools developed meet the effectiveness criteria. (4) Based on the normalized gain index, it was found that in trial I there was an increase in students' mathematical communication skills with "low" criteria with a score of 0.30 (g ≤ 0.3) and in trial II there was an increase in scores with "medium" criteria. with a score of 0.42 (0.3 N-Gain ≤ 0.7).

Abstract

This study aims to examine the influence of raw material quality on the texture and taste of donuts produced by the Donut MSME in Naga Timbul Village. This MSME faces challenges in producing donuts with a soft texture and delicious taste due to inconsistencies in raw materials and limited production equipment. The lack of understanding regarding the relationship between raw material quality and the final product further exacerbates this issue. This study employs a qualitative method with data collection techniques including interviews with MSME owners and employees, observations of the production process, and analysis of the raw materials used. This approach was chosen due to the MSME’s limited laboratory equipment, making the analysis more descriptive and based on firsthand experiences of business actors. The results show that the quality of raw materials significantly affects the texture and taste of donuts. High-quality raw materials, such as fresh wheat flour and other premium ingredients, produce donuts with a softer texture and better taste. Conversely, lower-quality raw materials result in harder-textured donuts with a less appealing taste. This study provides recommendations for MSMEs to pay more attention to raw material selection to improve product quality without relying on advanced equipment.

Abstract

Empowering Micro, Small, and Medium Enterprises (MSMEs) based on local wisdom plays a crucial role in improving the local economy while preserving regional culture. This study aims to analyze the empowerment strategies of local wisdom-based food MSMEs in Ladang Bambu Village. The method used involves a participatory approach through training, mentoring, and market access strengthening. The results indicate that the preservation of traditional recipes, the use of local ingredients, and attractive packaging are key to success. Furthermore, collaboration with the government and private institutions is essential to provide support in terms of facilities, technology, and marketing. In conclusion, empowering MSMEs based on local wisdom not only improves community welfare but also preserves local cultural identity. The implementation of MSME empowerment strategies for food-based local wisdom in Ladang Bambu Village plays an important role in boosting the local economy while preserving culture through local food products. The research method employed in this study is a qualitative approach, with data collection techniques including interviews, observations, and literature studies. The findings show that the potential for local wisdom-based food in Ladang Bambu Village can be developed through business management training, product innovation, digital marketing, and increased access to capital. The main challenges faced are limited knowledge of technology, limited market access, and a lack of understanding of business management. Therefore, collaboration between the government, MSME actors, and the community is necessary to create an ecosystem that supports the sustainability of local wisdom-based enterprises.
