The Rajaban tradition is a tradition of religious rituals as an expression of gratitude and moments to commemorate historical events, one of which is the change in the direction of Qibla from Baitul Maqdis to the Kaaba in Mecca. Based on these problems, in this article, it is shown by using the study of Graph Theory, namely the eccentric digraph to determine the center of the earth's region. Data processing is done by making the Kaaba and the seven continents on the earth's surface as a point on graph G and the side connecting the points is the distance (in km) with physical boundaries between them being considered non-existent. The results of the discussion show that the Kaaba in Mecca is the center of the earth's area with ec(v1) = 12,039 = rad(G).

Pembelajaran Flipped Classroom merupakan model pembelajaran berbasis teknologi yang relevan dengan perkembangan pembelajaran di era revolusi industri 4.0. Secara garis besar, pelaksanan model pembelajaran Flipped Classroom diawali dengan pembelajaran di rumah dengan melihat video secara online dibantu dengan LKPD. Hal ini menyebabkan siswa harus memiliki kemandirian belajar yang tinggi agar penerapan model pembelajaran Flipped Classroom dapat maksimal. Penelitian ini merupakan penelitian eksperimen murni (true experimental) dengan rancangan random atau disebut juga randomized pretest – postest control group design dengan pendekatan kuantitatif. Penelitian ini dilaksanakan di kelas VIII SMP Muhammadiyah 1 Gamping dan melibatkan 68 siswa. Data diperoleh melalui pretest dan postes kemudian dianalisis dan dihasilkan suatu kesimpulan. Hasil penelitian menunjukkan bahwa peningkatan self-regulated learning siswa yang belajar menggunakan model Flipped Classroom lebih baik daripada siswa yang belajar menggunakan model konvensional.

A flipped classroom is an innovative approach that focuses on student centered learning. It swaps the arrangement of knowledge different from traditional classroom. This study aims to describe the learning outcomes of SMP Negeri 1 Sewon students in which learned using Flipped Classroom Learning Model comparing to the Direct Learning Model, and to find out whether the flipped classroom learning model is effectively used in mathematics learning. This is quasi-experimental research. The research subjects were divided into 2 groups, namely the experimental group (using flipped classroom learning model) and control group (using direct learning model). The results showed that the flipped classroom learning model was more effective than direct learning model in terms of its self-regulated learning (SRL). It can seem from the results of statistic data analysis which shows a significant difference. So, it can be concluded that flipped classroom model can be used as an alternative learning in the classroom.

Abstract. The purpose of this study is to analyze problem-solving on HOTS problems in terms of early mathematical ability. This research method uses qualitative methods. The subjects in this study were students of class XI MIPA. The technique of determining the subject in this study began by grouping students into three groups of early mathematical abilities, namely high, medium and low. Then 3 students were taken as subjects, namely one subject for each group whose problem-solving steps met the problem-solving steps of Krulik & Rudnick. The data collection technique begins by grouping the categories of early mathematical abilities, giving math problem-solving tests and interviews on selected subjects to describe mathematical problem-solving and achievements on the HOTS indicator. Based on the results of math problem-solving tests and interviews on the subject, the results of this study showed that subjects with high early mathematical abilities were able to fulfill the read the problem step, explore step, select a strategy step, solve step and look back step so that the subject reached the indicator of analyzing, evaluating and create. Subjects with the medium category of initial mathematical ability were able to fulfill the read the problem step, the explore step, then select a strategy step, and the solve step, so the subject had not yet reached the creating indicator. Subjects with low mathematics initial ability category were only able to fulfill the read the problem step, the subject did not achieve all of the HOTS indicators.

Reasoning is a very important aspect of mathematical ability in learning mathematics. Mathematical reasoning ability is not optimal, one of which is learning that does not involve students enough. One of the learning models that encourages students to be active in the learning process is the PACE model. The aim of this research is to determine the effectiveness of PACE learning assisted by Google Classroom on students' mathematical reasoning abilities. This research uses a quantitative approach with a quasiexperimental research design and the form used is the nonequivalent pretest-posttest control group design. In this design there are two groups selected randomly (cluster random sampling).The data collection techniques used are test techniques and observation techniques. Based on research results, PACE learning assisted by Google Classroom is effective for mathematical reasoning abilities. This can be seen from the obtained which is greater than , so is rejected. This means that the results of the mathematical reasoning ability test of students using Pythagorean material who used PACE learning assisted by Google Classroom completed classical learning. Then we get so is rejected. This means that the proportion of students who complete learning with PACE learning assisted by Google Classroom is more than the proportion of students who complete learning with Problem Based Learning (PBL). Apart from that, we get then is rejected. This means that the average mathematical reasoning ability of students using PACE learning assisted by Google Classroom is more than the average mathematical reasoning ability using PBL. And obtained then is rejected. This means that the average mathematical reasoning ability after being subjected to PACE learning assisted by Google Classroom is better than the mathematical reasoning ability of students before being subjected to PACE learning assisted by Google Classroom.
