Abstract

This paper presents the effect of volume fraction of rice husks on the mechanical properties of bamboo fiber/unsaturated polyester composites. The composite specimens were made from bamboo fiber with fixed volume fraction of 40% and rice husk particle as filler with volume fractions varied 0%, 10%, 20% and 30%. Matrix used was unsaturated polyester resin. Bamboo fibers and rice husk were surface treated using alkali solution 4% (by weight) for 2 hours. The manufacturing process of composite was using hand layup method. The specimens were tested in tension, bending and in impact loading. The results show that the addition of rice husk particles up to volume fraction of 20% does not result in a decrease of tensile strength, but after a volume fraction of 20%, the tensile strength tends to decrease. In bending test, the rice husk volume fraction up to 20% increase the bending strength, but after that then it tends to decrease. However the bending modulus seems unaffected by the volume fraction of rice husk. Similar to the bending modulus, the impact strength is not significantly affected by the volume fraction of rice husk.

Abstract

Penelitian tindakan ini dilakukan dalam dua siklus. Masing-masing siklus terdiri dari empat kegiatan, yaitu perencanaan (planning), tindakan (acting), observasi (observing) dan refleksi (reflecting). Pada siklus pertama, teknik supervisi individual  diberikan dalam bentuk pemberian informasi teoritis tentang pengembangan rencana pelaksanaan pembelajaran. Hasil dari kegiatan siklus pertama masih belum dapat dikatakan berhasil, hal ini disebabkan peroleh rata-rata sekor para guru masih di bawah 56 atau sedang. Pada siklus kedua, teknik supervisi individual ditindaklanjuti dengan memberikan bantuan praktis, di mana peneliti dan peserta secara kolaboratif mengembangkan rencana pelaksanaan pembelajaran. Pada siklus kedua, hasil pengembangan silabus mata pelajaran yang disusun oleh guru meningkat, hal ini dibuktikan dengan peroleh rata-rata sekor para guru sebesar 100 atau amat baik. Dari hasil penelitian dapat disimpulkan bahwa terjadi peningkatan kompetensi pedagogik guru dalam mengembangkan silabus. Pada siklus pertama penguasaan kompetensi guru adalah 50% atau sedang, kemudian meningkat menjadi 100% atau baik. Artinya teknik supervisi individual memberikan dampak positif terhadap peningkatan kompetensi pedagogik guru dalam mengembangkan rencana pelaksanaan pembelajaran

Abstract

Kemampuan berpikir kreatif merupakan kemampuan yang diperlukan di abad 21 sehingga kemampuan tersebut merupakan hal yang perlu diperhatikan. Penelitian ini akan membahas tentang kesalahan siswa dalam menjawab soal tes kemampuan berpikir kreatif matematis pada materi pecahan berdasarkan prosedur Newman. Tujuan penelitian ini adalah untuk mengetahui kesalahan-kesalahan yang mungkin dilakukan siswa terkait soal-soal tes kemampuan berpikir kreatif materi pecahan. Subjek dalam penelitian ini adalah 13 siswa SMP di Pagaralam yang berada di kelas VII. Metode yang digunakan dalam penelitian ini adalah descriptive-qualitative. Dalam hal ini, instrumen yang digunakan adalah soal-soal esai tes kemampuan berpikir kreatif dengan indikator-indikator yaitu kelancaran, fleksibilitas dan kebaruan. Hasil penelitian menunjukkan bahwa siswa melakukan kesalahan dalam Reading, Comprehension, Transformation, Process Skill, dan Encoding berdasarkan prosedur Newman. Penelitian ini menyatakan bahwa kesalahan dalam reading menyebabkan siswa tidak mencapai indikator kelancaran dengan maksimal. Kesalahan pada comprehension menyebabkan siswa tidak dapat mencapai indikator fleksibelitas dengan maksimal. Selain itu, pencapaian pada indikator kebaruan perlu didukung oleh kemampuan siswa untuk menjawab soal tanpa melakukan.kesalahan.

Abstract

A Community Service activity entitled “Diffusion of Innovations of Indonesian Realistic Mathematics Education to Mathematics Teachers of Junior High School (SMP) in Sleman Regency through Lesson Study” aims at diffusing Innovations of Indonesian Realistic Mathematics Education (Pendidikan Matematika Realistik Indonesia: PMRI) to Mathematics Teachers of SMP in Sleman Regency who are actively participating in SubjectBased Teachers Group (Musyawarah Guru Mata Pelajaran: MGMP) of Mathematics. The diffusion is conducted through Lesson Study. Specifically, this PPM activity aims at improving understanding of mathematics teachers as participants on excellences of PMRI and Lesson Study and increasing teachers’ willingness to implement PMRI in the Lesson Study format. Objects of the study were 25 mathematics teachers of SMP in Sleman Regency actively participating in MGMP. The first activity was socialization on PMRI and Lesson Study. It was conducted on July 12, 2012 in the Mathematics Education Laboratory and was joined by 25 participants. The second activity was in a workshop on Development of Learning Tools and the implementation of the plan phase which was conducted on July 26, 2012 in the Mathematics Education Laboratory with 25 participants. Meanwhile, the third activity was the implementation of the do and see phase conducted on August 9, 2012 at SMP Muhammadiyah III Depok Sleman with 25 participants. In the beginning and the end of the activity, all participants were given written questions to reveal their understanding on PMRI and Lesson Study. In the end of the activity, questions were added about advantages of PMRI and Lesson Study. All participants of the activity stated that PMRI and Lesson Study are very advantageous for students and teachers. All of them also committed to implement PMRI in the Lesson Study format. Considering the results above, it can be concluded that this PPM activity is successful to improve the understanding of mathematics teachers as participants on excellences of PMRI and Lesson Study and also works to increase their willingness to implement PMRI in the Lesson study format. In addition, all participants also hope on the follow-up of this activity. Therefore, Department of Education, Youth and Sport of Sleman Regency and UNY (Yogyakarta State University) need to establish cooperation to facilitate the implementation of PMRI in the Lesson Study format for mathematics teachers of SMP in Sleman Regency.Keywords: realistic mathematics education, and mathematics lesson study

Abstract

Pandangan matematika sebagai aktivitas insani rupanya merupakan pilihan yang tepat dalam kerangka menjadikan warga negara Indonesia menjadi literasi dalam matematika. Kemampuan literasi matematika harus dikuasai oleh setiap warga Indonesia dalam menuju  “mathematics for all”. Fungsi dari mathematics for all tentu saja harus (1) mendasari matematika lebih lanjut serta (2) dapat diaplikasikan dalam kehidupan keseharian umumnya bagi mereka yang tidak akan melanjutkan studinya (Soedjadi, 1999).   Kata kunci : Matematiks sebagai aktivitas insani, mathematich for all

Abstract

The ability of mathematical representation in learning is very necessary, especially in learning mathematics. The purpose of this study was to examine the ability of students' mathematical representation in learning mathematics. Data is collected through related journals for review. The research method chosen in this study was to find the SRL (Systematic Literature Review) method. Data collection was carried out by documenting and reviewing all articles on mathematical representation abilities published in the period 2016-2021. The articles used in this study were 29 international journal articles indexed by Scopus and 31 nationally accredited which were obtained from the undergraduate google database using the publish or perish application. The ability of mathematical representation is very closely related to students, especially in learning mathematics, which is a form of interpretation of students' thoughts on problems that are used as tools to find solutions to mathematical problems.The results showed that the ability of mathematical representation in learning mathematics can be improved by providing innovations in learning and providing opportunities for students to develop mathematical representation skills by fulfilling the indicators of the mathematical representation itself. Thus the students' mathematical representation ability is no longer in the low category in solving mathematical problems.
