<p class="Abstract">The aim of this research was to determine the analysis of science process skills in textbooks of chemistry grade XI in SMA N 1 Teras, Boyolali. This research used the descriptive method. The instruments were developed based on 10 indicators of science process skills (observing, classifying, finding a conclusion, predicting, raising the question, hypothesizing, planning an experiment, manipulating materials, and equipment, Applying, and communicating). We analyzed 3 different chemistry textbooks that often used by teachers in teaching. The material analyzed in the book was solubility and solubility product concept in terms of concept explanation and student activity. The results of this research showed different science process skill criteria in 3 different chemistry textbooks. Book A appeared 50% of all aspects of science process skills, in Book B appeared 80% of all aspects of science process skills, and in Book C there was 40% of all aspects of the science process skills. The most common indicator in all books was observing (33.3%), followed by prediction (19.05%), classifying (11.90%), Applying (11.90% ), planning experiments (9.52%), manipulating materials and equipment (7.14%), finding conclusion (4.76%), communicating (2.38%). Asking the question and hypothesizing did not appear in textbooks.</p>

The purpose of this research is to improve the science process skills and students' scientific attitude through the use of practicum-based learning. The method used is quasy experiment. The research design used is Nonequivalent Control-Group Design. Sampling technique of this research using purposive random sampling. Data collection techniques are: test, observation and questionnaire techniques. The research was conducted at one of Vocational High School in Cirebon City, SMK RISE Kedawung Cirebon. The implementation of this practicum-based learning can be fully (100%) implemented. Practicum-based learning is able to improve students' science process skills before the learning (pretest) the average student score is 38.13, while after learning is 85.27. N-Gain obtained in each indicator of science process skill are observation, prediction, and use a tool or material or source are 1 (one); apply the concept, communicate, interpretation are 0.90;� to plan an experiment is 0,74; The hypothesized is 0.62. The value of improvement students' science process skill indicator based on the highest observation is the indicator of using the tool or the material or the source 47, and the lowest is indicator 28. Improvement scientific attitudes of students based on the highest is prioritizes the proof indicator� 48, and the lowest is the indicator of a positive attitude to failure 28. Practicum-based learning is very good and appropriate to be implemented in the learning process because it can be provide experience and skills in working in laboratory environment carefully and according to the procedureKeywords: Practicum-based learning;� Science process skills; �Scientific attitude
