Abstract

Perencanaan merupakan bagian penting yang menentukan arah suatu proses pembelajaran. Akan tetapi, sebagian besar guru di sekolah mitra memiliki kendala dalam menyusun perencanaan pembelajaran secara mandiri. Oleh karena itu, kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan kompetensi guru dalam menyusun dokumen perencanaan pembelajaran inovatif untuk mendukung implementasi kurikulum merdeka di SMP. Unsur inovatif pada perencanaan pembelajaran ini difokuskan pada Higher Order Thinking Skills (HOTS), Information and Communication Technology (ICT), kolaborasi, dan Penguatan Pendidikan Karakter (PPK). Pelatihan ini melibatkan delapan guru di SMP Muhammadiyah 5 Tanon, Sragen, Jawa Tengah, Indonesia. Hasil PkM menunjukkan bahwa berdasarkan analisis dokumen, 50% guru dapat menyusun perencanaan pembelajaran sederhana dan memuat unsur inovatif. Selain itu, berdasarkan hasil survei pasca pelatihan, berturut-turut 87,5% dan 100% guru menyatakan memiliki keterampilan dan siap untuk menyusun dokumen perencanaan pembelajaran sederhana dan memuat unsur inovatif. Hal ini menunjukkan adanya peningkatan kompetensi guru dalam menyusun dokumen perencanaan pembelajaran inovatif untuk mendukung implementasi kurikulum merdeka. Meskipun demikian, perlu pendampingan lebih lanjut agar peningkatan kompetensi guru dapat lebih optimal.  Abstract. Planning is an important part that determines the direction of a learning process. However, most teachers in partner schools need help preparing learning plans independently. Therefore, this Community Service activity aims to improve the competence of teachers in compiling innovative learning planning documents to support the implementation of an independent curriculum in junior high schools. This innovative learning planning element focuses on Higher-Order Thinking Skills (HOTS), Information and Communication Technology (ICT), collaboration, and Strengthening Character Education. The training involved eight teachers at a private junior high school (SMP Muhammadiyah 5 Tanon) in Sragen Regency, Central Java, Indonesia. The results of this Community Service show that based on the document analysis, 50% of teachers can compile simple learning planning documents that contain innovative elements. In addition, based on the results of post-training surveys, 87.5% and 100% of teachers stated that they have skills and are ready to compile simple learning planning documents containing innovative elements. These results show an increase in teacher competence in collecting innovative learning planning documents to support the implementation of an independent curriculum. However, further assistance is needed so that the improvement of teacher competence can be optimized.

Abstract

This research investigates the mathematical concepts embedded within Batik Truntum motifs, including geometry, analysis, arithmetic, and algebra. Employing a qualitative methodology with an ethnographic approach, the study addresses four critical questions: "Where should I begin the search?", "How do I locate the concepts?", "How do I identify significant findings?", and "How do I comprehend these findings?". Through addressing these questions, the researcher successfully analyzed the mathematical concepts inherent in Batik Truntum. Of the four primary mathematical concepts, only geometry was substantiated by experts, encompassing sub-concepts such as geometric transformations, line relationships, and planar geometry. Specifically, transformation geometry includes translation and reflection, while the study of line relationships involves line alignment, and planar geometry covers the topic of circles. This research aims to ensure that the millennial generation remains connected to batik as a vital part of Indonesia's cultural heritage, preventing cultural erosion amidst technological advancements through the intricate and exploratory study of mathematics.

Abstract

Previous studies have tried to improve students' independence in online mathematics learning. However, the Flipped Learning model integrated with GeoGebra is scarce as none of the existing syntaxes accommodate the model. As the existing syntax is based on three phases: pre-class activity, in-class activity, and post-class activity. This research aims to develop GeoGebra-based Flipped Learning syntax to increase students' independence in learning mathematics. The main difference between the existing syntax and the developed one is the integration of GeoGebra in the pre-class activity. The integration is based on previous studies showing that using GeoGebra can improve student’s learning achievements. It research employed the Design-Based Research (DBR) model involving 125 second-year undergraduate students of a private university in Indonesia. The syntax results were obtained from the study, indicating an increase in the average value of student independence in learning mathematics based on learning independence, confidence, level of discipline, sense of responsibility, level of initiative, and self-control. This developed syntax is expected to help teachers streamline online mathematics learning.

Abstract

The Covid-19 pandemic has forced an immediate transition from face-to-face learning in classrooms to online learning, including math learning. Mathematics with abstract working objects is not easy to learn online. So, an excellent self-regulated learning ability is required. So far, many efforts have been made to improve self-regulated learning in mathematics learning. However, there are still gaps in improving students' self-regulated learning ability in online mathematics learning, especially in relation to the integration of GeoGebra into the Flipped Learning approach. The purpose of this study is to examine the effectiveness of integrating GeoGebra into the Flipped Learning approach to improve students' self-regulated learning ability in learning mathematics online during the Covid-19 pandemic. This research is a quasi-experimental study with a pretest-posttest control group design to compare the effectiveness of a GeoGebra-integrated Flipped Learning approach. A conventional Flipped Learning approach and a conventional learning approach increase students' self-regulated learning level in constructing their understanding of mathematical concepts during online learning in the Covid-19 pandemic. The study involved 60 students randomly selected from one of Indonesia's private universities. They were divided into three groups representing each approach. Pretest and posttest results were quantitatively analyzed using Normalized Gain (N-Gain) Score, Cohen's d effect size, and statistical descriptive. The analysis results revealed that GeoGebra-integrated Flipped Learning is more effective in increasing students' self-regulated learning level in online mathematics learning than the other two approaches. It is expected that the results of this study can provide insights into alternative solutions for improving the quality of online mathematics learning by increasing the level of self-regulated learning of students.

Abstract

The growth of housing in Indonesia has been very significant in recent years.   The most found type of house is type 36. One of the areas with high purchasing power for housing is the Kendal Regency, which became the object of this study. Often housing projects experience delays caused by internal and external factors that can interfere with the duration of the initial planning. The effort that can be made to maintain the level of progress of the project is by acceleration. The optimal cost of the project due to the reduction in duration can be completed by acceleration techniques (Crashing) as linear programming models.   In this study, Crashing and Linear Programming methods were chosen to optimize the value of adding costs to accelerate three samples of housing. Housing A, Housing B, and Housing C. The data collected is in the form of RAB, scheduling, and other supporting documents. Linear programming in this study using LINDO software. The plan to accelerate the construction of type 36 housing is carried out using alternative overtime working hours, adding 1, 2 and 4 working hours on critical activities of each project. The optimum time is selected based on the smallest cost slope value from the program crashing calculation. The result is shown that in housing A the most optimal addition was 2 hours of overtime with a total extra cost of Rp.   54,643,600 and a total acceleration of 15 days. In housing B, the optimum value of time and cost is by adding 4 hours of overtime with a total additional cost of Rp.   21,644,140 with a 27-day acceleration. In housing C, the development optimizes by adding 4 hours of overtime at an additional cost of Rp.   74,587,900 with a 29-day acceleration.

Abstract

Yogyakarta's ox carts, though culturally significant and increasingly rare, have not yet been explored as sources of mathematical concepts. This study addresses the urgency of preserving and utilizing these traditional artefacts as contextual tools for mathematics education. This ethnographic research aims to identify and describe mathematical concepts—geometry, arithmetic, algebra, and statistics—embedded in various parts of the Yogyakarta ox cart. Data were collected through interviews and observations, with the subject being an ox cart craftsman and the object being the mathematical concepts found in the cart’s section. Data analysis followed the Miles and Huberman model. The findings reveal four major mathematical concepts: (1) Geometry, including rectangles, trapezoids, rhombuses, triangles, reflections, translations, rotations, parallel and intersecting lines, angles, and tessellations; (2) Arithmetic, involving arithmetic sequences and division operations; (3) Algebra, in the form of variable terms; and (4) Statistics, represented by the mode topic. These findings contribute to the field of ethnomathematics by introducing a new cultural context and supporting the development of mathematical materials based on local wisdom, making learning more realistic. Integrating local heritage into mathematics instruction can foster a deeper understanding, increased student engagement, and a greater appreciation for cultural diversity, offering meaningful and realistic learning experiences.
