Abstract

Until now student mastery of the material geometry is still relatively low. Many difficulties experienced by students in understanding the geometry of the material, one of which is the difficulty in proving. In addition, the study is not yet available devices that can specifically serve the needs of teachers in the teaching of mathematical proof. Therefore, it is necessary to develop learning tools of proof that can help teachers and train students in the proof of the geometry in school. In this study the evidence used strategy is the strategy of abductive-Deductive. This study aims to develop and produce learning device geometry proof. This type of research is the development of research refers to the model of Plomp through four stages, namely a preliminary investigation stage, the design stage, the stage of realization / construction, and stage of the test, evaluation and revision. This research trials in SMA Laboratorium Unsyiah Banda Aceh. The research showed the average score validator for RPP 4.52, 4.58 LKPD, teaching materials and test 4.54 4.30 learning outcomes, adherence to the 91%, the average score of 3.73 practicality test, 86% students with a positive response, and 80.7% of students complete. This shows that the learning device valid criteria, practical and effective way to improve the geometry of high school students.

Abstract

This study aims to observe customer's responses toward car fragrance products, examine the volatility and properness of the essential oil-based product. Essential oil is a group of vegetable oil in form of liquid that easily evaporated at room temperature. Hence it gives unique scents. This research is carried out with a descriptive method using a qualitative approach. The data analysis technique of this research is using SWOT analysis (Strength, Weakness, Opportunity, and Threat) and calculation of Cost of Goods Sold to compare the two samples of car freshener. The result of this research showed that product A which is based on patchouli essential oil, citronella, coffee, and gadenza essential was more preferable by the customer with the range of selling price in IDR 19.000 – IDR 22.000 than product B. SWOT analysis explained that the product's strength is the multifunction of the product as aromatherapy and the opportunity of the product to compete in a wider market; while the weakness of the product is the high labour of production process. The total calculation of the Cost of Goods Sold for product A is IDR 15.440 and product B is IDR 15.960.
