Abstract

Enhancing mathematical creativity requires more learning activities that foster creative thinking. However, teachers need more resources and activities to nurture students' creativity in mathematics effectively. Therefore, this study aimed to design STEAM-based geometry activities using the Engineering Design Process (EDP) to explore how such projects can enhance students' mathematical creativity. In this study, creativity focuses on how students use geometric principles to design Wingko Babat as an Indonesian cuisine, making culturally meaningful connections and solving design challenges. The study involved research and development using the analysis, design, development, implementation, and evaluation (ADDIE) model, continuing with a descriptive qualitative approach. The activities designed for the STEAM-Geometry projects allow students to think creatively and elaborate on the engineering design process. Through expert reviews that involved multiple educators, the design activities on the STEAM-Geometry project are reliable and valid. The findings show that the EDP on Geometry project enables students to think creatively. The findings imply that teaching geometry can develop the students' mathematical creativity through the engineering design process in STEAM activities. Furthermore, it indicates that the design activities encompass more than just understanding geometry; they also nurture creativity by applying STEAM principles in the engineering design process. Integrating STEAM principles within culturally meaningful, geometry-based tasks enhances students' critical thinking, creativity, collaboration, and real-world problem-solving skills, preparing them to tackle complex challenges beyond the scope of mathematics.

Abstract

Sistem perpipaan (plumbing) adalah sistem saluran air pada sebuah gedung atau rumah yang terdiri dari air bersih, air limbah, dan air hujan. Mengingat pentingnya hal ini, pengetahuan tentang sistem plambing perlu dimiliki oleh setiap stakeholder. Tujuan dari penelitian ini adalah untuk mengetahui persepsi konsumen, pengawas, dan pengetahuan perencana terhadap sistem plambing pada perumahan rakyat dan juga untuk mengetahui kondisi sistem plambing yang terpasang pada perumahan tersebut. Metode penelitian yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan data primer berdasarkan hasil survei terhadap pengembang perumahan rakyat di Solo, dan Semarang. Hasil penelitian menunjukkan bahwa pengetahuan konsumen tentang sistem plambing pada bangunan rumah kurang baik. Sementara itu, pengetahuan perencana dan pengawas rumah tentang sistem perpipaan sudah baik. Perencana dan pengawas bangunan tahu bahwa ada peraturan dan standar mengenai sistem dan peralatan plambing. Namun, standar nasional SNI 8153:2015 tentang sistem plambing belum sepenuhnya diterapkan diperumahan. Penyediaan rumah dengan harga terjangkau berdampak pada penggunaan peralatan dan sistem plambing. Karena pertimbangan biaya produksi pembangunan dan harga jual rumah, Spesifikasi Peralatan yang digunakan belum dapat secara optimal memenuhi standar yang ada.

Abstract

Various activities especially in fulfillment daily needs, generate a lot of waste. One of the negative effects of waste generation is the contribution of greenhouse gas emissions to the atmosphere which causes global warming. Every location has waste, both organic and non-organic, or other types. The open space in Bendan Dhuwur campus area is dominated by organic waste due to leaf fall from many trees around. This is a concern because there is no proper waste management and it is immediately burned. This study focuses on analyzing the composition of waste and calculating the contribution of CO2 emissions from domestic waste generation at Bendan dhuwur campus of UPGRIS Semarang. The method used is random sampling accompanied by quantitative descriptive measurements and analysis. The result of the research shows that the calculation of waste composition for leaf waste is 3.58 x 10-3 Gg/year; twig waste 3.6 x 10-4 Gg/year; paper waste 3.57 x 10-4 Gg/year; plastic waste 2.02 x 10-4 Gg/year and CO2 emissions = 2.12 x 10-3 Gg/year; CH4= 2.57 x 10-5 Gg/year (leaves), CO2 = 2.18 x 10-4 Gg/year; CH4=2.58 x 10-6 Gg/year (twig), CO2 = 1.53 x 10-4 Gg/year; CH4= 2.56 x 10-6 Gg/year (paper), CO2 = 0.02 Gg/year; CH4= 1.45 x 10-6 Gg/year (plastic) Keywords: waste, CO2, CH4
