Abstract

The purpose of this research is to create a practical guide alternative based environment for senior high school students and to determine validity, practicality and effective level of the practical guide it self. Type of this research is the Research and Development (R & D). The development model used in this research is Plomp models which consists of three phases: preliminary research, prototyping phase, and assessment phase. The research instrument questionnaire of validity, practicality and effective sheet. Practical guide alternative based environment validated by 4 validators and tested to 17 students of class XII IPA 3 SMAN 1 Rambatan and 29 students of class XI IPA 4 SMA N 1 Kec. Guguak of academic year 2017/2018. The momen kappa of validity was 0.79. The practicality level of teachers response questionnaire was 0.84. Based on questionnaire of student response, the value of momen kappa is 0,77 in SMAN 1 Rambatan and and 0,90 in SMAN 1 Kec.Guguak with high category practicality for small group test, and momen kappa value is 0,81 in SMAN 1 Rambatan and 0,84 in SMAN 1 Kec. guguak with highest category practicality on field test. The effective level of teachers response questionnaire was 0,89. Based on questionnaire of student response, the value of momen kappa is 0,76. The results of research it can be concluded that the practical guide alternative based environment for senior high school students has a high validity category, highest practicality category, high effectivity category from students and highest effectivity from teachers
