Abstract
Indonesia is the second largest biodiversity country in the world. Indonesia has a variety of top agricultural and plantation commodities, whereas each commodity has premium products which are normally related to its specific character/flavour and are generally associated with the producing origins. Specific character/flavour is represented by composition of metabolites each origin. To find out the specific character/flavour found in various Indonesian plantation commodities, clustering is needed. In this paper, we perform clustering on one Indonesian plantation commodity based on their metabolites composition. Metabolite compositions of samples of several origins of the commodity are clustered using the Hard C-Means algorithm with the Xie-Beni index as the cluster validity. Our present results confirm that each origin has a unique characteristic and belongs to a separate cluster.

Abstract
An abstract is a brief summary of a research article, thesis, review, conference proceeding or any in-depth analysis of a particular subject or discipline, and is often used to help the reader quickly ascertain the papers purpose.[1] When used, an abstract always appears at the beginning of a manuscript or typescript, acting as the point-of-entry for any given academic paper or patent application. Abstracting and indexing services for various academic disciplines are aimed at compiling a body of literature for that particular subject. The terms precis or synopsis are used in some publications to refer to the same thing that other publications might call an "abstract". In management reports, an executive summary usually contains more information (and often more sensitive information) than the abstract does.

Abstract
The education distribution problem is a matter how the education system can give a broad opportunity toward all citizens to get the education so that education can be a tool to build the human resource to support the country development. To solve that problem, the government tries to do several ways both conservative and innovative ways. However, that is not absolutely solving the problem. One of them is how expensive the cost is for High School education both financial and social matter if there are so many programs of building school until the countryside. Along that matter there are so many students who have interest to continue their study and they have to find a boarding house which make them easily to reach the school they study because it is nearer to their school. The problem is how is the students- achievement who stay at the boarding house and who stay at with their parents on mathematics at SMUN 2 Tarogong Garut Academic year 2000/2001. Based on the formulated problem so the research is aimed 1) to know the students- achievement who stay at the boarding house 2) to know the students- achievement who stay at with their parents 3) to know the significant difference between them. The hypotheses of the research is 1) All students in the classroom receive the same mathematics lesson 2) The teachers at SMUN 2 Tarogong has done the mathematics learning and teaching according to the Senior High School curriculum 3) The mathematics teacher at SMUN 2 Tarogong has a competence and authority to teach at Senior High School. From the hypotheses above it is known that there is no difference between the students- achievement who stay at the boarding house and who stay with their parents. Based on the calculation using statistic test, the conclusion are 1) There is a difference between students- achievement who stay at the boarding house and who stay with their parents. 2) The students who stay at the boarding house is less than the students- achievement who stay with their parents. According to the result of the questionnaire given by the researcher to the students, it is considered that the students- achievement who stay at the boarding house is less than who stay with their parents and it is also caused by the lack of parents- attention. According to the result of the research, it is suggested to the students who stay at the boarding house to spend the leisure time to learn more in order to get a better achievement, and to the parents whose children stay with them to give more attention and chance to their children to learn, so that their achievements will be better and increase.

Abstract
This paper is a little practical reflection of the idea proposed by Freudenthal in his book titled ‘Revisiting Mathematics Education-. Theoretically, a fundamental study of more philosophical mathematical meanings was discussed by Freudenthal through the terms ‘wiskunde- and ‘wiskunst-. In essence, wiskunde means mathematics as an exact science, while wiskunst means an art in mathematics and science. Although there has been a lot of research that shows the success of RME in learning, the results of research that can contrast explicitly how the wiskunde and wiskunst phenomena work in the process of solving mathematical problems are still rarely found. This study aims to see the tendency of students towards the phenomenon of wiskunde or wiskunst in working on elementary math problems then describe the psychological factors and impacts that might be influential. This study used literature review and qualitative methods through the interview process for students who were given two elementary school math problems. Four out of forty students from fourth semester were chosen to be interview respondents to represent variations of the unique answers. Data analysis was carried out through a hermeneutic approach to student answers and interview transcripts. Research shows that the wiskunde phenomenon looks more dominant than wiskunst. This is thought to be related to the symptoms of psychological blockages of student-s college who are predominantly working on elementary math problems still using the very formal formulas, they should still be able to show a way of thinking like an elementary school kid. The impact of this wiskunde tendency indicates the ‘matherate- of students who have become blunt. The contrast of wiskunde and wiskunsts character and its reflection to the philosophy of education are discussed boldly in this paper.

Abstract
In general, teachers have a good knowledge and familiar with the stages of various learning models. This can be seen in the stages compiled in the learning implementation plan (RPP) they design. However, in the implementation the teacher has not implemented learning model according to the planned stages. This study aims to develop learning videos to be used as a reference for teachers in implementing a problem-based learning model (PBL). Video development is done by using a 4-D model with stages of Define, Design, Develop and Dissemination. The teacher as the model in this video is a mathematics teacher who has experience in teaching and being trained to implement the PBL model. The video shows the stages of learning with the PBL Model which is complemented by the text that appears as a guide at each stage carried out by the teacher. This video was shown to the teacher through the FGD, the teacher was given a questionnaire to provide responses to the videos they were watching. The teacher provides input from aspects of the format, content and language used. The average score from the results of the questionnaire is 3.8 in scale 4. All teachers stated that this video greatly helped them in preparing for the implementation of the problem-based learning model.

Based on the results of expert validation, the devices and media used in learning meet valid criteria with a percentage of 98%, as well as practicality in learning seen from the activities of lecturers and students where the first to last meetings continue increasing so that the devices and media used are practically practical. From the evaluation of effectiveness,it can be seen in the results of the preetest and posttest scores of students with a significant value of 10.81. From the results of the analysis, it can be said that the use of lectora and wingeom media in learning in geometry material is practical, valid and effective. The use of lectora media can make the study more interesting, and the use of wingeom applications makes it easier for students to abstract 3-dimensional construction on geometry material and makes it more real
