ANALISIS DAN STANDARISASI BUKU KIMIA SMA KELAS XII SEMESTER I BERDASARKAN STANDAR ISI KTSP

The analysis and standarization of Senior High School (SHS) chemistry text books for class XII semester I based on the contents standard of KTSP curriculum was described in this study. The aim of research are: (1) to analyse chemistry text book that commonly used in SHS at North Sumatera, (2) to compose a list of suitable and systematic chemistry materials for teaching SHS students class XII semester I based on the KTSP, (3) to determine suitable and proper chemistry materials for teaching SHS students class XII Semester I, (4) to develop a standard chemistry text book for learning and teaching process of SHS students class XII semester I, and (5) to explore the opinion of chemistry teachers about the developed chemistry text books. The study was a descriptive study. The population were: (a) all text books of SHS class XII semester I, and (b) certified SHS chemistry teachers who taught in class XII. The samples were five text books under criteria as follows: the text book should be based on KTSP curriculum, pass the assessment of Pusat Perbukuan Depdiknas, and commonly used in SHS Schools in North Sumatera. The instrument used was questionnaire with category sheet with indicators included, which then identified by percentage of appearance for each book and the categories. The results showed that the percentage of book A, B, C, and D were 78%, 86%, 93%, 94%, and 97% respectively. Listed chemistry materials suitable for teaching SHS students at class XII semester were Colligative properties of solutions: concentration of solutions, vapor pressure lowering, boiling point elevation, freezing point depression, diagram PT, osmotic pressure, and colligative properties of electrolytes; Redox reactions and electrochemistry: redox reactions, Voltaic cells, Voltaic cells applications, corrosion, electrolytic cells, Faradays law, and electrolytic cells applications, Chemical periodicity: chemical periodicity of main groups and transitions of elements, chemical elements properties, applications and effects of the element utilization; and Nuclear chemistry: radioisotope properties, nuclear reactions, applications and effects of radioisotope. Teachers opinion revealed that they agree (average 3.49) with the listed chemistry materials. The standard chemistry text book for SHS developed were consisted of Chapter 1. Colligative Properties of Solutions, Chapter 2. Redox Reactions and Electrochemistry, Chapter 3. Chemical Periodicity, and Chapter 4. Nuclear Chemistry. All chapters were supported by illustration, problem-solving, and evaluation. The developed SHS chemistry text book was evaluated by the chemistry teachers to validate the contents of the book as reference materials. The results showed that the respondents were agree (average 3.6) with contents of the text book. It was concluded that SHS chemistry teachers in North Sumatera respond positively to the content, design, illustration and evaluation provided in the textbook developed in this study and it is suitable to be used in teaching and learning chemistry.
