Abstract: Due to difficulties in learning geometry, the teacher plays an important and active role in creating students who have good problem solving skills. The teacher also has to test the level of geometrical thinking of students based on Van Hiele's theory to find out the students understanding about geometry material, so the teacher can overcome the difficulties of students in learning geometry. This research is designed to explore and describe the process of geometry problem solving based on Van Hiele's theory. Therefore this research used descriptive exploratory. It used qualitative approach. The subject of this research is limited to University of Muhammadiyah Sorong students which obtained the level of visualization, analysis, informal deductive and will be analyzed based on the gender. Data of this research is 1) Geometry Van Hiele Test; 2) Problem Solving Test; 3) Interview. The conclusion of this research is: 1) At the level of male visualization thinking is to identify problem and determine goal using language problem. While at the level of women visualization, it reached on determining goal, ; 2) the level of male analysis thinking is able to pass five steps in problem solving by using own language but are less systematic. While level of female analysis thinking is able to pass five steps in problem solving systematically; 3) level of male deductive formal thinking is to pass five steps problem solving systematically and using own language. While level of female deductive formal thinking is able to pass five steps problem solving systematically and explaining by using own language.

This study aims to explore and describe the process of problem solving geometry reach the level of visualization, analysis and informal deduction based on the Van Hiele theory. This type of research is descriptive explorative and qualitative approach. Subject of the study was obtained from the high school students who were tested on the level of Van Hiele geometry. Each level of visualization, analysis and informal deduction taken two learners who can communicate well. The results of this study indicate that solving problems in geometry learners who attained think visualization is to identify problems and set goals using the language question. Troubleshooting on the geometry of learners who attained think theanalysis is through fifth troubleshooting step IDEAL using their own language, but less systematic.

The purpose of this study was to analyze the problem solving abilities of SMP Kartika I-6 grade VIII students, who learn with problem solving strategies based on Polya steps in solving story problems. This research is descriptive with a qualitative approach. The subject of this study was class VIII1 student. After  problem solving learning strategy are  applied, given test problem solving ability in participants and the results are analyzed based on the steps of pattern.Test results raising students in three levels of problem solving skills, namely a high level of 25 %, medium 50 %, lower 25%. Based on the indicator of problem solving, it is known that the ability of students in understanding problems and arranging settlement plans is in the high category, while in implementing the completion plan it is categorized as being moderate and checking the answers back at a low level.

<p><em>This study aims to describe the thinking process of students in solving geometry problems in terms of gender. This research is qualitative-descriptive. The subject of this research is the Semester V student of Bukittinggi IAIN Mathematics Education. The instruments used are tests and interviews. the thinking process of Bukittinggi IAIN PMTK students in geometry problem solving tends to be different in the stages of processing information on men and women. In planning and resolving problems in female subjects more analytical in completing compared to male subjects. But the subject of men is </em><em>more</em><em> able to describe the problem. Male subjects can see with a different perspective. But this depends on the questions given and the understanding of concepts and experiences that have existed in the previous subject related to the questions given</em><em></em></p><p>Penelitian ini bertujuan untuk mendeskripsikan proses berpikir mahasiswa laki laki dan perempuan dalam memecahkan masalah geometri. Penelitian ini bersifat kualitatif-deskriptif. Subjek pada penilitian ini adalah satu mahasiswa laki laki dan satu mahasiswa perempuan Pendidikan Matematika IAIN Bukittinggi yang memiliki kemampuan matematika yang setara dan komunikatif. Adapun instrumen yang digunakan adalah tes pemecahan masalah geometri dan wawancara. Proses berpikir mahasiswa dalam  memecahan masalah geometri cenderung  berbeda pada tahapan mengolah informasi pada laki laki dan perempuan. Dalam merencanakan dan menyelesaikan masalah pada subjek perempuan lebih analitis dalam menyelesaikan dibandingkan dengan subjek laki laki. Namun subjek laki laki lebih bisa menggambarkan dan mengabstrakkan permasalahan. Subjek laki laki bisa melihat dengan sudut pandang yang berbeda. Namun hal ini tergantung pada soal yang diberikan serta pemahaman konsep dan pengalaman yang telah ada pada subjek sebelumnya terkait soal yang diberikan.</p>

The purpose of this study was to analyze the scope related to the subject of problem-solving skills based on multiple representation in 2016 – 2020 with 20 documents through bibliometric analysis. The research method used was a literature study through all the articles analyzed in this study. The articles were taken from the Scopus database with sampling in 2003 – 2020, resulting in 29 scientific work data exported in *.ris (RIS) and *CVS formats. Then, those data were processed using VOSviewer and Microsoft Excel. The results of publications in the last five years have increased. Indonesia is the dominant country in publicizing papers about this topic. Institutions from Germany managed to publish most of the documents about multi representation. Meanwhile, Poland is the origin country of the authors with most publications. The visualization of research trends on multi representation resulted in four main clusters: (1) multi representation related to students, representation, and learning processes (2) multi representation as a class (3) multi representation related to the problem (4) multi representation as a model and process. Meanwhile, Indonesian researchers are very active in contributing to this topic, in line with the number of publications by country, namely Indonesia.

The Subject

The intoxication of the occupants is hardly considered in the fire safety design, due to the lack of data on the subject. Recent research experiments into the influence of alcohol on evacuation have shown evidence that there might be a correlation between the development of drunk behaviour and the surroundings or context in which the occupants are situated. That is why the experiment in this report investigated the development of drunk behaviour in a group of people within a party environment, independently of alcohol, with the use of non-alcoholic beer as a placebo. The participants were put through 3 identical exercises, which were aimed at testing their balance, reaction times, concentration, hand to eye coordination, problem solving skills, cognitive skills and cooperation. In addition to that they performed 2 evacuations that were used to interrupt their ’drunk behaviour’ and test their reaction, decision and overall evacuation times. They were also analysed for signs of drunk behaviour with video and sound recordings. The results showed clear reduction of performance in the tests for concentration, hand to eye coordination, problem solving skills, cognitive skills and cooperation after the consumption of the beer, but little change in the balance tests. Apart from that, some of the participants showed signs of drunk behaviour, such as playfulness and increase in noise after the alcohol was consumed and these were reduced after the environment changed. Based on this it was concluded that even with non-alcoholic beer some of the participants developed drunk behaviour, like that observed in previous experiments with the use of alcohol.
