Abstract

This research aims to produce a medium of learning in the form of game CD Interactive discussion on part of the subject hydrocarbon reactions to senior high schools that can be used as a medium of learning and to find out its feasibility. Interactive CD media in the form of the game was created using Macromedia Flash 8 program. This type of research is done is research Research and Development (R&D), the research methods used to produce a particular product, and test the effectiveness of the product. Interactive CD in a game that made ​​30 people tested for class XI science students SMA Negeri 1Batang Ana it he terms of form, motivation, and practicality. Terms of the content by theUNP chemistry lecturer, chemistry teachers SMA Negeri 1Batang Anai, chemistry teachers from other schools that are all a total of 11students majoring in chemistry and a total of 30 people. The instrument used was questionnaire in the form of Likert scale. Feasibility of the media are made of the analytical results obtained by questionnaire lecturer and teacher at 3.45, from 3.46 for the student questionnaires, and questionnaires from students majoring in chemistry at 3.40. The results showed that the Interactive CD media in the form of this game is worthy of discussion part of the subject used in hydrocarbon reactions both in terms of shape/appearance, content, motivation and practicality.

Abstract

 ABSTRACT Inulin-RBB is a compound that used for screening of inulinase bacteria. Formation of inulin-RBB compounds in the mass variation of inulin and the reaction temperature and the determination of RBB concentation in inulin-RBB has been carried out. Determination of RBB concentration in inulin-RBB on the HPLC using an ODS C18 column, l 592 nm, mobile phase ethanol-water (60:40) and flow rate 1 mL/min. RBB concentration of  inulin-RBB in the mass variation of inulin (2 g, 4 g and 6 g) which was reacted with 0.5 g of RBB at 50°C is 4.74%, 23.14%, and 38.54%, respectively. RBB concentration of inulin-RBB in the reaction with 0.5 g of inulin 4 g of RBB at the reaction temperature variations (40, 50 and 60 ° C) is 18.86%, 23.14%, 9.40%, respectively. Key words: RBB, inulin-RBB, inulin, HPLC
