AbstrakPenelitian ini bertujuan untuk menghasilkan instrumen asesmen matematika berupa soal tes HOTS yang valid dan reliabel, dan mendeskripsikan kualitas soal tes HOTS untuk mengukur keterampilan berpikir tingkat tinggi pada peserta didik SMP kelas VIII. Penelitian ini merupakan penelitian pengembangan yang diadaptasi dari model pengembangan Borg & Gall, yang meliputi langkah-langkah sebagai berikut: penelitian dan pengumpulan informasi, perencanaan, pengembangan produk awal, uji coba terbatas, revisi produk awal, uji coba lapangan, dan revisi produk akhir. Hasil penelitian menunjukkan bahwa instrumen asesmen HOTS berupa soal tes HOTS yang terdiri dari 24 butir soal pilihan ganda dan 19 butir soal uraian dari aspek materi, konstruksi, dan bahasa dinyatakan valid dan layak digunakan. Instrumen tersebut mempunyai koefisien reliabilitas sebesar 0,713 (soal pilihan ganda) dan sebesar 0,920 (soal uraian). Soal pilihan ganda memiliki rata-rata tingkat kesukaran 0,406 (sedang), rata-rata daya pembeda 0,330 (baik), dan semua pengecoh berfungsi baik. Soal uraian memiliki rata-rata tingkat kesukaran 0,373 (sedang) dengan rata-rata daya pembeda 0,508 (baik).

AbstrakThe study was to describe the implementation of Problem-Based Learning (PBL) toward the improvement of students ' Higher Order Thinking Skill (HOTS) ' characters; and (3) in overall the obstacles that had been encountered within the implementation of PBL process were related to the teachers' unpreparedness, the time allocation, the unequal students' input, the students' learning habits and the difficult assessment. The data gathering process was conducted through the test, the self-assessment and the open questionnaire. The quantitative data analysis was conducted inferentially using multivariate and univariate analysis, while the qualitative data analysis was conducted descriptively. The results of the study showed that: (1) the implementation of PBL had been more effective in comparison to the expository one in terms improving the students' HOTS; (2) the implementation of PBL had not been more effective in comparison to the expository one in terms of improving the students

This research is aimed to explore the cultural elements especially in Sasak architectures in Lombok Island such as a home living (Bale), worship building (masjid), lumbung (sambi) in ethnomathematics point of view. This research uses qualitative approach with cognitive (anthropology cognitive). The interviewees are the experienced custom leader and humanists who has conducted the research on Sasak society. Meanwhile, the data collection method used the participant, observation and documentation. Data analysis on this research is not only based on the researcher is interpretation but also the idea structure of the society.  This research shows the evidence of sensitivity on the use of numbers practiced by Sasak ancestor long time ago in doing the measurement using their anthropometric ability (Ethnomathematics). The architecture products of sasak society also describe that sasak society is more focus on the process than the final products itself which describes the consistency in conducting role and cultural device which control the desire of individual construction.

Marriage is an essential part of life for most people. In the Javanese tradition, great attention is paid to the weton of the couple through Javanese Primbon. It predicts the fate of the couple in the marriage. This prediction of the Javanese outcome after the wedding has some numerical values. Therefore, this study aims to uncover these numerical values using ethnomathematics. This research uses a qualitative method. Analyzing the Javanese Primbon documents is meant to explore the numerical value of Javanese people. Also, analyzing the data using the Javanese Primbon documents was not only based on the interpretation of the researcher but also the result of discussions with cultural and mathematical experts. This study proposes numerical values such as number bases, remainder theorem, modulo, and modulus of the congruence in formal mathematics, which is associated with matchmaking using Javanese Primbon.

Penelitian ini bertujuan menghasilkan produk media berupa komik pembelajaran matematika yang dapat meningkatkan motivasi dan prestasi belajar matematika siswa kelas V SD. Penelitian ini merupakan penelitian pengembangan, yang terdiri dari: (1) penelitian dan pengumpulan data, (2) perencanaan, (3) pengembangan draft produk, (4) uji coba lapangan awal,  (5) revisi hasil uji coba, (6) uji coba lapangan, (7) penyempurnaan produk hasil uji coba lapangan, (8) uji pelaksanaan lapangan, dan (9) penyempurnaan produk akhir. Subjek uji coba adalah siswa kelas V SDN Glagah Yogyakarta. Subjek uji coba satu-satu terdiri atas tiga orang siswa. Subjek uji coba kelompok kecil terdiri atas sembilan orang siswa yang belum terlibat dalam uji coba satu-satu, dan subjek uji lapangan terdiri atas 54 orang siswa dari kelas VB dan kelas VC yang tidak ikut dalam uji coba satu-satu dan uji coba kelompok kecil. Hasil penelitian menunjukkan bahwa media yang dikembangkan ini mendapatkan penilaian dari para ahli dengan kategori “baik”, penilaian guru dan siswa yang menggunakan media komik menyatakan praktis, sehingga media pembelajaran ini layak digunakan. Hasil uji lapangan menunjukkan media komik pembelajaran matematika yang digunakan dapat meningkatkan motivasi belajar siswa sebesar 0,65 tergolong dalam kategori sedang menurut skala gain, sedangkan prestasi belajar siswa sebesar 0,73 tergolong dalam kategori tinggi menurut skala gain. ____________________________________________________________________________________________________________________________________ DEVELOPING COMIC MEDIA FOR THE TEACHING OF MATHEMATICS TO ENCHANCE THE MOTIVATION AND MATHEMATICS LEARNING OUTCOMES GRADE V ABSTRACT This research aims to produce a product in the form of mathematics teaching comics which can improve motivation and learning achievement of students of grade V of SD. This research is research and development study consisting of nine stages, namely: (1) research and data collection, (2) planning, (3) developing the draft product, (4) the initial field trial, (5) revising the test results (6) field trials, (7) refinement of the results of field trials of the products, (8) implementation of the field test, and (9) improvement of the final product. The subjects were students of SDN Glagah Yogyakarta. The subjects of the trial consisted of three students. The trial subjects test consisted of nine students did not involve in the one-on-one trial, and the field test subjects consisted of 54 students from classes VB and VC which were not participate one on one trial test and small group trial. The developed media gained result from the experts who considered it good, the assesment of students and teachers showed that the comic media was practice and feasible. Based on the field test the comic media of mathematics learning could improve learning motivation of 0.65 as moderate  category, the learning performances was 0.73 as high category according to gain scale.
