Abstract

Analisis bangunan bersejarah Panggung Krapyak memiliki tujuan untuk mengetahui sejarah Panggung Krapyak dan mengetahui pendekatan terhadap bangun geometri Panggung Krapyak. Jenis penelitian berupa penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian ini merupakan bangunan bersejarah Panggung Krapyak. Teknik pengumpulan data yang digunakan pada penelitian ini yaitu wawancara dan dokumentasi (observasi) secara langsung. Wawancara dilakukan dengan warga setempat yang berada di sekitar bangunan dan dokumentasi dilakukan secara langsung. Teknik analisis data dilakukan dengan menganalisis bangunan yang terkait dengan geometri seperti bentuk bangunan pada Panggung Krapyak. Hasil dari penelitian ini diperoleh yaitu Panggung Krapyak pada awalnya dimaksudkan sebagai tempat panggung tempat sultan dan keluarganya beristirahat dan mengawasi anggota keluarganya berburu rusa, merupakan bangunan yang terdiri dari dua lantai, terbagi dalam 9 segmen dan mempunyai pintu ke 4 arah mata angin. Bentuk Panggung Krapyak tersebut menyerupai bentuk-bentuk geometri yaitu kubus.

Abstract

The existence of a Student Worksheet (LKPD) is able to improve the ability to understand students' concepts. This research aims to develop LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the ability to understand concepts based on validity, practicality, and effectiveness in geometric transformation materials. The type of research used is research and development (R&D) with a 4D model, namely the defining stage, the design stage, the development stage, and the deployment stage. This study was conducted at SMP Negeri 1 Tegalrejo with a sample of 31 students in class IX B. The results showed that an LKPD based on ethnomathematics of batik motifs typical of Magelang was produced to increase understanding of the concept of geometric transformation that is valid or feasible in terms of the validity value of LKPD by material expert validators and teaching material expert validators, which is 86.31% with a very valid category. Judging from the practicality value of LKPD by the response of students, which is 89.61% with a very practical category. The results of the standard gain increased concept understanding ability were obtained by 5 low classification learners, 10 medium classification students, and 16 high classification students. Increasing understanding of the concept of geometric transformation using LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the effectiveness value of the pretest and posttest results calculated using the standard gain formula <g> , which is 0.62 with a moderate category, so that LKPD is said to be effective.
